What is Billing Software?

An invoice is a kind of bill that shows what was bought and sold between a buyer and seller or service provider. Its job is to keep track of sales and let customers know what they owe, making sure they pay for what they got on time.

A billing and invoicing system lets you track services and products, create and send invoices, and accept payments. Knowing how to develop a billing software can automate repetitive tasks, saving your team time and effort. Some invoicing tools even track the time spent on client work to generate hourly bills.

Billing and invoicing are similar but have different meanings. An invoice is what businesses send to clients showing what they bought and how much they owe. Customers get a bill to show what they bought and have to pay. Also, invoices have a payment deadline, while bills need to be paid as soon as they're received.

In addition to basic functions, you can manage debt, handle collections, access reports, process payments, taxes, and balance financial books. This is just the beginning of what such systems can offer.

Your unique business needs play a crucial role in designing a billing app. Every business, regardless of size, benefits from a basic billing and invoicing system. These systems enable faster payments, quicker reinvestment, and prompt market response. Minimize non-compliance errors and payment delays, allowing you to better serve your clients and customers.

Using Off-the-Shelf vs Custom Billing Software

Invoices are a headache for businesses, big or small. It's not just about getting paid, it's about getting paid on time. Many companies struggle with late payments, with up to 78% of them admitting to it. Doing things manually, like entering data and reminding customers to pay, isn't efficient anymore. That's why more businesses are turning to billing software. It helps ease the pain, keeps data safe, and automates finances and invoices.

Business owners need to know how to create a billing software. This automation improves performance and reduces errors.

Decide who will develop it, how much you can spend, and why you're making it. Once you've got all that sorted, you can move on to the next step.

To make a software project work, you have to use your time, energy, and resources wisely. It's important to know why making billing and invoice management software.


First, decide on your software development business model. This model outlines how the software will be developed and used.

Here are some questions to consider:

  • What problems should the billing software address?
  • How many people will use it?
  • Is your workload stable, or does it vary throughout the year?
  • Do you need custom web or mobile app development services, or both?

This list isn’t comprehensive. But it helps you understand the direction of billing software requirements.

Team assembling

To build a successful app, your development team should specialize in fintech. Billing software developers should also know cloud computing, automation, and ML.

You have two hiring options:

1. In-house team:

Suitable for large enterprises wanting full control over the development process. However, this approach requires time for recruitment, interviewing, and onboarding.

2. Offshore development team:

Outsourcing speeds up the process, as the service provider handles recruitment. It also allows access to a broader talent pool and reduces operating costs. For example, at Relevant, we can start a project within two weeks of the initial meeting with a customer.

Product development

With an MVP, the development process is more focused and efficient. However, two crucial factors need attention:

1. APIs and Integrations: require features like bill tracking, basic transactions, and chat support. These can be built from scratch or integrated using third-party services. Ensure your app can securely and smoothly integrate third-party APIs.

2. Security: Since billing software handles personal and financial information. It must have robust security features. This includes secure application logic and role-based access control.

Testing and Deployment

Test and maintain your software to ensure readability. Eliminate technical debt, and ensure ease of use for team members. Regular maintenance ensures that your code remains clear and functional. It reduces the risk of errors and improves usability. Billing software is a dynamic product, so optimize its design and functionality.

Remember, invoicing software is a long-term investment. It will be a valuable tool for years, so it deserves a carefully planned approach from the start.
