Let's freeze your invoices

Information stored on invoices are fundamental for a correct accounting, for this reason these details shound't change over time.

  • Snapshot for customer data, custom fields, currency and invoice header
  • Admin Panel to modify snapshots
  • Company profile properly applied to each invoice

Billing Extension "freezes" the issued invoices' data to avoid billing errors

Reducing your Paper-Flow

WHMCS generates a large number of invoices. We have decided to optimize this process with OneInvoice and OnePayment. Both allow to issue a maximum of one invoice per month for each customer.

  • With OnePayment you receive a monthly payment from each customer
  • Save up to 18% on transaction fees*
  • 95% reduction on invoices issued and emails sent*
  • Enhanced Renewals for an easier management of renewals
  • Less invoices to record and print

* Calculations based on our case study

Tailor-made for you!

With Billing Extension you can customize invoices, proformas and credit notes individually with no limitations.

  • New Auto-tags to personalize sequential numbering
  • Suppressing unwanted invoices (eg. zero amount, full discount or fully paid by credit)
  • Protect invoices from being edited or deleted

For an easier experience all options are manageable from settings page and grouped by categories.

The best from WHMCS

As you know, WHMCS is a complex and feature-rich system, unfortunately some of its features are only hinted or completely missing. With Billing Extension we have fixed many dysfunctional sides to make the most of all its potential.

  • Ability to create credit notes and unpaid invoices
  • Correct invoicing of credit and overpayments
  • Warning System to detect invoicing issues

Our goal is to keep improving both the module and the basic WHMCS features to provide an ideal user experience.

Customize your billing

All Billing Extension options are applicable globally, on groups or on individual customers. For example, you could use OneInvoice for all customers, OnePayment for a group only, and turn off automatic invoicing for specific customers. Basically, the most specific rule will have priority.

  • Set multi-level rules
  • New filters and options to export to spreadsheets
  • Possibility of inserting an invoice text based on the customer type
