Invoicing software FAQs

Invoicing software is an online or desktop tool that helps businesses create, send, and manage invoices more efficiently. With features like customisable templates and automated reminders, it streamlines your billing process and simplifies payment collection.

E-invoicing, or electronic invoicing, is the process of creating, sending, and receiving invoices in a digital format. Unlike traditional paper or PDF invoices, e-invoices are structured for seamless integration between systems, allowing businesses to automate billing and payment processes.

Traditional invoicing typically relies on a slow, manual process, which includes filling in billing details, printing paper copies, and physically sending them to customers. With e-invoicing, businesses can reduce admin tasks, improve accuracy, and track payments more efficiently. Customers receive invoices electronically, making it easier for them to pay on time. Our e-invoicing software integrates with partner tools within the Sage Network and trusted payment providers, simplifying the entire process.

Sole traders often rely on Excel due to availability and budget constraints. Excel might be useful if you only occasionally need to generate and send invoices. As your business grows, maintaining invoices in Excel formats can be daunting. Modern small businesses, medium companies and sole traders typically switch over to invoicing software to automate invoicing processes and manage payments easily.

If you have been using Excel templates or spreadsheets to create and keep track of your invoices, you can easily import your data to Sage. With a variety of customisable, professional yet simple templates, you'll never have to rely on Excel again.

Manually creating invoices with tools like Word or Excel can be time-consuming and makes it hard to manage your cash flow. Business invoicing software streamlines the process, saving you time and helping you stay on top of your billing. By implementing a solution with e-invoicing features, you can:

  • Automate your invoicing: streamline tasks like creating, sending, and tracking invoices.
  • Track payments effortlessly: monitor outstanding and upcoming invoices in one centralised system.
  • Manage late payments easily: set up automated reminders to encourage customers to pay on time.
  • Save time and reduce errors: digitise your invoicing process for better efficiency and accuracy.
  • Present a professional image: create polished, branded invoices that reflect your business.

Online invoicing systems help you focus on what matters most—running your business—while keeping your payments organised and efficient.

To be legally valid, an invoice must include an offer made by one party and accepted by another. While requirements vary by region, invoices typically need:

  • Invoice number: a unique identifier for tracking.
  • Seller and buyer information: names, addresses, and contact details for both parties.
  • Description of goods/services: quantities, unit prices, taxes, and discounts.
  • Total amount due: the full amount owed, including taxes or discounts.
  • Payment terms: due date, accepted payment methods, and any late payment penalties.

Absolutely. You can easily import existing invoices and historical data when switching to Sage from other systems like Xero or Quickbooks. Import effortlessly with simple CSV templates or with 1-1 support whenever you need it.

Choosing the best invoice software means finding a solution that fits your business needs and budget while offering simplicity, scalability, and seamless integration.

Look for an online invoice system that prioritises security, compliance, and quality customer support. Read user reviews and industry recommendations to identify trusted providers. Go beyond just traditional invoicing features. Make sure the invoicing software include comprehensive financial dashboards with key metrics and offer built-in financial reporting and analytics, so you can stay on top of how your business performs.
