Moneybird WHMCS addon

This module sets up synchronisation between WHMCS and Moneybird.


  • WHMCS 7.6 or higher;
  • EU VAT addon enabled;
  • Composer


  • Run composer install;
  • Upload all files to modules/addons/moneybird/.


Configure a cronjob to run every 5 minutes.

php -q /path/to/whmcs/modules/addons/moneybird/cron.php

The cron is disabled by default. It can be managed through the addon settings in Setup > Addon Modules. We suggest to leave the cron disabled until you have configured your ledgers and taxes.


You can activate this module via Setup > Addon Modules in WHMCS.

This addon requires you to configure:

  • A Moneybird access token;
  • A Moneybird administration id;
  • The first invoice you want to synchronise;

A token can be created via

Ledgers and tax rates


Moneybird calls ledgers categories. It allows you to group your revenue and expenses. You can map product groups to ledgers in Moneybird. This is done via Addons > Moneybird > Ledger mapping.

It is recommended to map product groups to categories but not required.

If you are unsure about ledgers, please consult with an accountant first.

Tax rates

We strongly recommend to map your taxes in WHMCS to your tax rates in Moneybird. This is done via Addons > Moneybird > Tax mapping.

If you are unsure about your taxes, please consult with an accountant first.

Enable the cron

You can enable the cron via its setting in Setup > Addon Modules in WHMCS.

How does it work?

Once you've got everything set up, configured your ledgers and taxes, you can enable the cron. From that point onwards it will synchronise your contacts and invoices to Moneybird. Invoices are synced once, contacts are checked and updated every time a new invoice is created. It also synchronises financial mutations once a mutation has been linked to an invoice.

Contacts and invoices

The addon will keep track of both contacts and invoices in WHMCS and Moneybird.


Every contact is given a new id in Moneybird. This is done to prevent overlap since Moneybird uses the same numbering for both suppliers and customers. If a supplier in Moneybird would have the same id as a customer in WHMCS, its details would be changed.


WHMCS cannot be used as a single source of truth for accounting purposes. This is why invoices are given a new number in Moneybird. The original invoice id from WHMCS is set as a reference. This reference is also used by Moneybird to automatically map payments.

Payment methods and workflows

Different payment methods have different instructions. If you collect invoices via direct debit you probably don't want to add an instruction to pay via bank transfer. You can map your payment methods to different workflows. This is optional. If no mapping is configured it will pick the default workflow.

Financial mutations (payments)

Once a mutation has been linked to an invoice in Moneybird it will be detected as a payment. The addon will create a unique transaction in WHMCS based on the data it gets from the financial mutation in Moneybird. If an invoice has been paid for already (for example via PayPal) it will not add a duplicate transaction.


We strongly believe in the power of open source. This module is our way of saying thanks.

Sorry, no tests yet. Contributions are much appreciated.


This module is tested against WHMCS 7.6. It may work with previous versions too. It is recommended to test this in a safe environment before enabling it in production.
