Automated Billing Software - ScienceSoft

ScienceSoft applies 32 years in software development and practical knowledge of 30+ industries to help customers implement effective billing software.

Automated Billing System in a Nutshell

An automated billing system is designed to generate and send invoices, track and process payments. The solution is especially helpful for businesses with a large and diverse customer base, a wide range of products/services provided, subscription or retainer billing models.

The automated billing system integrates with ERP, CRM, accounting software, and payment gateways. The implementation of a custom automated billing system may take around 10 months. Average costs for building the automated billing system start from $120,000 and can reach $400,000 depending on the solution complexity.

When a Custom Automated Billing System is the Best Choice

We recommend developing the custom automated billing system in the following cases:

You need a modifiable automated billing solution that allows easy functionality extension when needed. For example, in our project for a leading European online marketplace, we developed a custom billing solution that can easily adopt new features due to layered architecture, clear separation of concerns (SoC), and standard APIs.

You need automated billing software to cover your specific business requirements, such as enabling non-linear invoicing workflows, custom calculations, creating custom triggers connected to specific events, or managing specific payments in highly regulated industries (e.g., healthcare, insurance, public sector).

A ready-made automated billing solution needs costly and effort-consuming customization to connect with your existing business-critical software (e.g., ERP, CRM, accounting system).
