Less is More

We designed new billing modes to reduce the number of invoices up to 80% and help you saving 18% on transactions fees.

  • Monthly invoices and payments
  • Postpone the issuing of invoices
  • Turn off billing for fraudulent orders
  • Simplified renewals with Enhanced Renewals

Send White-label monthly expiration notices and stop flooding customers with repetitive emails.

We want Problems

WHMCS lacks of features that every business need. We love to create innovative solutions to address this problem.

  • Issue credit notes, bill overpayments, tax funds
  • Stop issuing unnecessary invoices
  • Fully customizable late fees system
  • Transactions list and credit usage for customers

The module also integrates a system that lets you handle advanced tax rule configurations.

"Freeze" Invoice details

Once an invoice has been issued, it can't be altered or deleted. Billing Extension makes sure that it doesn't happen.

  • Snapshot customers and your business's details
  • Lock invoices and credit notes
  • Detect billing errors with Warning System

You can also set alarms to alert administrators about events that need to be followed up.

Do you "speak" European?

Thanks to Billing Extension your WHMCS will be EU-compliant. MOSS? VIES? No problem.

  • Automatic validation of VAT numbers on VIES
  • Correct taxation for intra/extra EU and special tax districts
  • Support for Cookie regulation

You can rely on a series of tools handling all aspects automatically including tax exemptions.

Have you ever seen...

a WHMCS Module that integrates an area where more features can be added by activating plugins? That's mind blowing 😊

We continue to create new ones! Stay tuned or suggest new ones.
