Find out about order processing systems, workflows, and improvement strategies to become an order processing expert and grow your bottom line.

Published July 2, 202621 min read Share

Every business that sells products relies on order processing—the end-to-end system that ensures customers get what they ordered when they need it.

Whether you run a small e-commerce store, a B2B wholesaler, or a global retailer, getting orders from placement to delivery efficiently is crucial.

Order processing sits at the heart of your supply chain management. It’s what turns a customer’s purchase into a fulfilled commitment.

For Canadian businesses, this matters even more as digital ordering continues to grow. Statistics Canada reported that retail spending in Canada reached $865.2 billion in 2024, including $73.7 billion in e-commerce revenue. Payments Canada also reported that e-commerce payments in Canada accounted for 546 million transactions worth $71.6 billion in 2023.

But order processing is not always smooth sailing.

Order processing involves multiple steps, such as checking stock, picking and packing items, and arranging shipping. If something goes wrong, delays, errors, and frustrated customers follow.

Bottlenecks in the process can cost businesses time and money, making it critical to have a system that works seamlessly.

Avoiding these issues starts with understanding the order processing cycle, common challenges, key metrics, and best practices to help you streamline operations and keep customers happy.

Key Takeaways

• Order processing is the end-to-end workflow that takes a customer order from placement to delivery, covering payment verification, inventory checks, picking, packing, and shipping.
• Order processing and order fulfilment are not the same. Fulfilment covers the physical picking, packing, and shipping stage, while order processing covers the full order lifecycle.
• The four main methods are manual, automated, just-in-time, and real-time processing. Most businesses use a mix depending on order volume and fulfilment speed needs.
• A strong order processing system reduces errors, speeds up fulfilment, improves customer satisfaction, and enables growth without proportionally increasing headcount.
• The six steps in the order processing cycle are order placement, confirmation, inventory sourcing, picking and packing, shipping, and delivery and customer support.
• Automation is one of the biggest levers for improvement because it can reduce repetitive work, cut errors, and help businesses absorb volume spikes.

Here’s what we’ll cover

What is order processing?

Order processing is the step-by-step workflow that ensures a customer order is prepared and delivered quickly and accurately, from the moment a purchase is made through to inventory checks, picking and packing, shipping, and tracking.

Whether handled manually, semi-automatically, or fully automatically, the goal is always the same: to get the right product to the right customer on time.

Without an efficient order processing system, businesses risk lost inventory, shipping errors, and slow fulfilment, all of which can affect revenue, customer satisfaction, and long-term trust.

That’s why having a structured, scalable approach to your order processing system is essential for sustainable growth.

What is the difference between order processing and order fulfilment?

Order processing is the full end-to-end workflow that takes a customer order from placement through to delivery. Order fulfilment refers specifically to the physical stage within that workflow—the picking, packing, shipping, and delivery of the product to the customer.

Order processing and order fulfilment are closely related concepts, with fulfilment sitting inside the broader order processing workflow.

Order processing covers the entire journey: from the moment a customer places an order—including the administrative steps like verifying payment, updating inventory, and confirming that order details are correct—through to the physical execution of getting the product to their door.

Order fulfilment refers to the physical execution stage of preparing and delivering the product, including picking, packing, and shipping.

In practice, these stages are tightly connected and often overlap. Many businesses treat fulfilment as part of the overall order processing workflow, especially when managing the full lifecycle from purchase through to delivery.

Order processing examples

To see order processing in action, let’s look at how real businesses have optimised their workflows to improve efficiency and customer satisfaction.

Salient Medical Solutions: Eliminating manual order processing at scale

Salient Medical Solutions, a medical device distributor in the United States, was struggling with manual order processing that led to errors, customer dissatisfaction, and limited scalability.

By using Sage 300 to automate orders, optimise inventory, and streamline financials, the company transformed its operations.

According to the Sage customer story, Salient improved business efficiency by 200%, grew revenue by 250%, and eliminated 38 hours a week of manual order processing.

As CFO Lydia Potter notes: “We can grow the business at unlimited scale without adding a lot of staff because we’re not doing anything manually other than pick and pack in the warehouse.”

Decathlon UK: Scaling up for demand

Decathlon, a major sporting goods retailer, needed a faster way to fulfil thousands of online orders each day.

To streamline its order processing, Decathlon installed a three-storey mezzanine with nearly 2,000 shelving units at its logistics centre.

This upgrade allowed the company to process around 3,000 online orders daily, improving order accuracy and reducing shipping delays.

Motocard: Speeding up fulfilment

Motocard, a Spanish motorcycle gear retailer, faced challenges keeping up with a growing number of online orders.

By integrating a warehouse management system (WMS) and reorganising its storage with picking shelves, Motocard improved order processing efficiency.

The result was 900 orders processed per day, with 90% of orders placed before noon dispatched the same day.

SAM Outillage: Automating for efficiency

SAM Outillage, a French tool manufacturer, struggled with slow order fulfilment due to outdated logistics processes.

To fix this, the company automated its order processing system, introducing a mini-load system and WMS. The impact was a 25% boost in productivity and 24-hour order fulfilment for orders placed before 4 p.m.

Each of these businesses tackled order processing challenges in different ways, whether through automation, better storage solutions, or smarter logistics.

How does sales order processing differ between B2B and B2C businesses?

B2C order processing is typically straightforward, with a single customer placing a single order. B2B sales order processing, on the other hand, often involves wholesale or enterprise contexts where orders are more complex, including purchase orders, credit terms, multi-location fulfilment, and contracts.

Let’s take a closer look at these factors:

• Purchase orders (POs): the buyer issues a formal PO before the seller processes the order, adding an approval and verification step.
• Credit terms: orders may be fulfilled before payment is received, requiring credit checks and accounts receivable management.
• Multi-location fulfilment: a single sales order may need to be split across multiple warehouses or distribution centres.
• Custom pricing and contracts: enterprise customers often have negotiated pricing, requiring the system to reference contract terms before confirming the order.

For businesses operating in both B2B and B2C channels, managing these two types of order processing within a unified order management system is a key operational challenge—and a core reason why scalable order processing software matters.

What are the main methods of order processing?

The main methods of order processing are manual, automated, just-in-time, and real-time order processing.

The right method for a particular business depends on its order volume, system maturity, and fulfilment speed needs.

Fully manual workflows may work for low-volume operations, while automated, real-time systems are designed for scale.

Manual order processing

Manual order processing is a traditional approach where staff record orders, update inventory, and arrange shipments by hand.

Manual processing can work for small businesses with low order volumes, but it is prone to errors and delays as orders increase.

Automated order processing

Automated order processing reduces manual effort by handling tasks such as order entry, inventory updates, and shipping logistics.

With tools such as WMS platforms, barcode scanners, and AI-driven software, businesses can process orders faster and more accurately.

Just-in-time order processing

Just-in-time (JIT) order processing focuses on minimising excess stock by processing orders only when needed.

While this approach reduces storage costs, any supply chain disruption—such as delayed supplier shipments, transportation issues, or sudden demand changes—can cause order delays.

Real-time order processing

Real-time order processing provides instant updates on order statuses, inventory levels, and shipping progress.

Industries like e-commerce, food delivery, and subscription services rely on real-time processing for speed and accuracy.

Every business needs a solid order processing system, and many use a mix of these methods to get the best results.

Why is a good order processing system important?

A well-designed order processing system reduces errors, speeds up fulfilment, improves customer satisfaction, and gives businesses real-time visibility into inventory and order status.

For growing businesses, a good order processing system can also make it easier to scale operations without proportionally increasing headcount.

A strong order processing system keeps your business running smoothly by delivering:

• Happier customers: orders that arrive on time and without mistakes build trust and encourage repeat business.
• Lower costs: streamlining order processing reduces manual work, errors, and unnecessary expenses.
• Better inventory control: real-time tracking helps prevent stockouts and overordering.
• Smarter decision-making: insights from order data allow for better forecasting and planning.
• A competitive edge: businesses that fulfil orders quickly and accurately are better placed to meet customer expectations.

In Canada, delivery expectations are also rising. Canada Post notes that Canadian e-commerce customers have higher expectations for service performance, delivery speed, and flexible delivery options, including weekend, same-day, and next-day delivery.

Advantages and disadvantages of order processing systems

Investing in a dedicated order processing system offers significant operational benefits, but it is important to weigh these against the challenges, particularly for smaller businesses.

The key advantages are:

• Accuracy: automated systems reduce the risk of human error in picking, packing, and shipping, minimising costly returns and customer complaints.
• Speed: automated order routing and real-time inventory updates can reduce order cycle times.
• Scalability: a well-configured system can handle significant volume increases, such as seasonal peaks, without requiring proportional increases in staff.
• Visibility: real-time dashboards give operations, sales, and finance teams a shared view of order status, inventory levels, and fulfilment performance.
• Cost reduction: over time, automation can reduce labour costs associated with manual order entry, error correction, and returns handling.

Potential disadvantages to keep in mind are:

• Implementation cost: enterprise-grade order processing systems require an up-front investment in software, integration, and staff training.
• Complexity for smaller teams: feature-rich systems can be overwhelming for micro-businesses or sole proprietors who do not need advanced functionality.
• Integration risk: connecting an order processing system to existing Enterprise Resource Planning (ERP), accounting, and logistics platforms introduces technical complexity and potential points of failure.
• Over-automation risk: fully automated systems can struggle with exceptions that require human judgment, like unusual orders or custom requests.

For most growing businesses, the benefits outweigh the drawbacks, but matching the system’s complexity to your actual operational needs is essential.

What are the steps in the order processing cycle?

There are six key steps in the order processing cycle: order placement, order confirmation, inventory sourcing, picking and packing, shipping, and delivery and customer support.

In many businesses, this cycle includes fulfilment activities like shipping and delivery as part of the end-to-end order processing workflow.

1. Order placement

Order processing starts when a customer places an order, whether online, over the phone, or in-store.

Your order processing system captures the details, including what the customer bought, how much they ordered, and where the order needs to go.

2. Order confirmation

Once an order comes in, you need to confirm the product is in stock, process payment, and verify customer details.

At this stage, customers usually get an email with their order number and an estimated delivery date.

3. Inventory sourcing

Your order processing system then locates the products in a warehouse or fulfilment centre.

If something is out of stock, you might source the item from another location or put the order on backorder.

4. Picking and packing

Picking and packing is the stage where the right items are selected from storage and prepared for shipping.

Whether your team handles picking and packing manually or uses automation, efficiency at this stage reduces errors and helps orders arrive in good condition.

5. Shipping

Once packed, the order is handed off to a carrier.

The order processing system generates a shipping label, and tracking details are sent to the customer so they can follow their package’s journey.

6. Delivery and customer support

The order arrives at the customer’s door.

If there’s a problem like a damaged item or a return request, your customer support team steps in to help. A smooth post-purchase experience builds trust and keeps customers coming back.

How does order processing fit into supply chain management?

Within the supply chain, order processing sits between demand generation, such as sales and marketing, and fulfilment logistics, such as warehousing, shipping, and last-mile delivery. Order processing acts as the operational bridge that converts customer demand into physical action.

Effective order processing in supply chain management depends on tight integration across several functions:

• Inventory management: real-time stock visibility ensures orders can be confirmed and fulfilled without delay.
• Procurement: for make-to-order businesses, a confirmed customer order may trigger a purchase order to suppliers, meaning order processing directly influences upstream supply chain activity.
• Warehouse management: picking strategies, storage layouts, and staffing levels in the warehouse are all shaped by order processing volumes and patterns.
• ERP integration: ERP systems consolidate order processing data with finance, inventory, and logistics, giving leadership a unified view of supply chain performance.

Together, these integrations position order processing as a central coordination point within supply chain management.

What factors can impact the order processing cycle?

The most common factors affecting order processing speed and accuracy include product complexity, order volume fluctuations, inventory accuracy, workforce efficiency, and shipping and logistics reliability.

Understanding these factors helps businesses identify where bottlenecks are most likely to occur so they can keep orders moving.

Type of products

Some products are easier to process than others.

Perishable goods, fragile items, or oversized shipments often need special handling, which can slow things down.

Digital products and small, durable items tend to move through the system faster.

Order volume and seasonality

Processing a handful of orders a day is very different from handling a seasonal rush.

Sales spikes, whether from holidays, promotions, or sudden demand, can overwhelm your system if you’re not prepared.

Without the right processes in place, businesses can struggle to keep up, leading to missed deadlines and frustrated customers.

Inventory management

Orders cannot be processed if the stock is not there. Poor inventory tracking leads to stockouts, delays, and even cancellations.

On the other hand, holding too much inventory ties up cash and warehouse space, and can increase the risk of an inventory write-down if products become obsolete, damaged, or harder to sell.

A real-time inventory management system helps you keep the right balance and ensures products are available when needed.

Workforce efficiency

Even with the best systems in place, order processing relies on people.

A well-trained team can keep things running smoothly, while understaffing, slow workflows, or a lack of automation can cause delays.

Investing in training, technology, and efficient processes helps businesses stay on top of orders.

Shipping and logistics

Getting an order out the door is one thing. Getting the order to the customer on time is another.

Delays with couriers or carriers, supply chain disruptions, or inefficient shipping processes can all slow down fulfilment.

Working with reliable carriers and optimising shipping methods can help minimise these issues.

What are the costs of order processing?

Labour, storage space, software, and shipping costs all contribute to the total cost of order processing.

Understanding these costs helps businesses identify where to invest in improvements and where inefficiencies are eroding margins.

• Labour: picking, packing, quality checking, and handling returns all require staff time. Labour is typically one of the largest variable costs in order processing, particularly for businesses with high order volumes.
• Shipping and handling: carrier fees, packaging materials, and dimensional weight charges can add up quickly, and errors that cause reshipments compound these costs.
• Inventory storage: holding stock in a warehouse or fulfilment centre carries fixed costs, such as rent, utilities, and security, and variable costs, such as handling and insurance. Overstocking increases these costs, while understocking leads to missed orders.
• Technology: order management software, WMS platforms, and ERP integration all involve licensing fees, implementation costs, and ongoing maintenance.
• Returns handling: processing returned items, including inspecting, restocking, or disposing of them, adds a cost layer that is often underestimated. In the US, the National Retail Federation estimated that 19.3% of online sales would be returned in 2025, which shows how returns can become a major operational consideration for online retailers.

Tracking these costs individually, rather than treating order processing as a single overhead line, gives businesses the data they need to prioritise improvements effectively.

What are the most important order processing metrics?

The most important order processing metrics are order accuracy rate, order cycle time, perfect order rate, order fill rate, and return rate.

Tracking these key performance indicators (KPIs) consistently gives businesses the data needed to identify bottlenecks and benchmark performance over time.

Order accuracy rate

Order accuracy rate measures the percentage of orders fulfilled without errors.

High accuracy means customers receive exactly what they ordered, leading to increased satisfaction.

Errors can result in returns, additional shipping costs, and potential loss of customer trust.

How to calculate order accuracy rate

The formula for order accuracy rate is:

A low order accuracy rate can signal a systemic issue in picking, packing, or order entry that is worth investigating.

Order cycle time

Order cycle time, also known as average order processing time, tracks the average time it takes to process an order from placement to delivery.

Shorter cycle times indicate a more efficient process, which can enhance customer satisfaction and reduce operational costs.

How to calculate order cycle time

The formula for order cycle time is:

Monitoring order cycle time over time helps identify whether process changes, such as new software, warehouse reorganisation, or additional staff, are having a measurable impact on speed.

Perfect order rate

Perfect order rate combines several factors, including accurate orders, on-time delivery, and undamaged goods, to assess the overall efficiency of your order processing.

A high perfect order rate reflects well on your entire supply chain.

How to calculate perfect order rate

The formula for perfect order rate is:

A low perfect order rate can suggest multiple issues across the fulfilment chain, such as inaccurate inventory, picking errors, late shipments, or damaged goods.

Order fill rate

Order fill rate measures the percentage of customer orders that are fulfilled completely from available stock without backorders or delays.

A high fill rate indicates effective inventory management and the ability to meet customer demand promptly.

How to calculate order fill rate

The formula for order fill rate is:

A consistently low fill rate points to inventory planning problems rather than order processing failures, which is useful for identifying where the real bottleneck sits.

Inventory turnover

Inventory turnover measures how often a business sells and replaces its stock over a set period.

Tracking inventory turnover alongside order fill rate can help you understand whether products are moving efficiently or whether excess stock is tying up cash and warehouse space.

How to calculate inventory turnover

The formula for inventory turnover is:

A low inventory turnover rate can point to overstocking, slow-moving products, or demand forecasting issues, while a high rate may suggest strong sales or potential stockout risk.

Return rate

Return rate tracks the percentage of orders that customers return.

Monitoring return rates can help identify issues with product quality, product descriptions, or fulfilment accuracy.

How to calculate return rate

The formula for return rate is:

There is no single benchmark that applies to every product category, channel, or country. For Canadian businesses, it is usually more useful to compare return rate by product category, sales channel, season, and fulfilment method.

How can you improve order processing?

The most effective ways to improve order processing are automating repetitive tasks, maintaining accurate inventory levels, optimising warehouse organisation, improving demand forecasting, and tracking performance metrics consistently.

These improvements work best when they are part of broader order management strategies that connect sales, inventory, fulfilment, finance, and customer service around the same order data.

Even incremental improvements in each area can compound into meaningful gains in speed, accuracy, and cost efficiency.

BDC recommends that entrepreneurs invest in retail management systems, inventory management tools, and point-of-sale systems, as well as supply chain technology to automate supplier orders, improve logistics, and optimise delivery routes.

Here are some effective strategies to consider.

Automate where possible

Manual processes slow things down and increase the risk of errors.

Automating tasks like order entry, inventory tracking, picking, and shipping can support faster fulfilment and fewer mistakes.

Integrated systems can also sync real-time data across departments, reducing miscommunication.

Keep inventory levels accurate

You cannot process orders efficiently if stock levels are wrong.

A real-time inventory management system prevents stockouts and overstocking, helping you balance supply with demand.

Barcode scanning and automated tracking can make inventory updates easier and more reliable.

Optimise warehouse organisation

A well-structured warehouse makes picking and packing much faster.

Grouping high-demand items together, clearly labelling sections, and using efficient storage layouts help reduce retrieval time.

Investing in a WMS can also optimise inventory placement and movement.

Improve demand forecasting

Knowing what customers will need before they order helps you avoid supply issues.

Using sales data, seasonal trends, and predictive analytics allows you to maintain optimal stock levels and plan for busy periods.

Streamline internal communication

Breakdowns in communication lead to delays and errors.

Ensure that all teams—sales, fulfilment, inventory, and customer support—have real-time access to order status updates.

Internal dashboards, automated alerts, and regular check-ins help keep everyone aligned.

Train and upskill staff

Even the best systems will not work well if employees are not trained to use them properly.

Invest in ongoing training so your team understands workflows, uses automation effectively, and can troubleshoot issues as they arise.

Offer partial order fulfilment

Sometimes, sending part of an order right away is better than waiting for all items to be available.

If stock is limited, consider shipping what is ready first and sending the rest later to keep customers satisfied.

Improve customer communication

Keeping customers informed reduces frustration and builds trust.

Automated email or SMS updates for order confirmations, shipping status, and delays help manage expectations and improve the buying experience.

Use mobile picking and barcode scanning

Equip warehouse teams with mobile devices for barcode scanning to speed up picking and reduce mistakes.

Scanning helps ensure the right items are packed, minimising returns and fulfilment errors.

Regularly review performance metrics

Tracking key metrics like order accuracy, fulfilment time, and return rates helps pinpoint inefficiencies.

Reviewing this data regularly allows businesses to adjust processes, eliminate bottlenecks, and continuously improve order processing.
