KashFlow Accounting

About this Addon Module

KashFlow is an accounting system for small businesses, particularly for businesses in the UK. This addon automates the entry of paid invoices into the KashFlow system.

The sync process runs as part of the daily cron job and creates clients, invoices, and transactions in KashFlow to mirror the invoice and transaction records in WHMCS.

Requirements

The KashFlow API requires SOAP in your server's PHP build. To check whether you have this, go to Utilities > System > PHP Info in WHMCS. If you do not see references to SOAP, you will need to recompile PHP.

The Syncing Process

If it is enabled, the sync process runs as part of the daily cron job.

The module can process a maximum of 200 invoices each time.
The system records errors in the log at Configuration () > System Logs or, prior to WHMCS 8.0, Utilities > Activity Log. We recommend that you review this periodically.
The first few runs may require a longer period of time as they attempt to sync all existing customers and paid invoices.

Multi-Currency Support

Both WHMCS and Kashflow support the use of multiple currencies.

When you use this:

WHMCS will connect to KashFlow and retrieve the configured currencies.
WHMCS will match the KashFlow currency codes with the codes in WHMCS.
When creating client accounts in KashFlow via this integration, WHMCS sends the appropriate currency ID. The currency code must match.

Make sure to configure all of your currencies in both KashFlow and WHMCS. You can find your configured currencies in WHMCS at Configuration () > System Settings > Currencies or, prior to WHMCS 8.0, Setup > Payments > Currencies.

Troubleshooting

KashFlow: Error Inserting Transaction xx

Seeing this error in the logs indicates that the transaction data does not meet Kashflow's requirements. Review the information at Billing > Transactions List and Billing > Invoices to ensure that all transactions and invoices have an assigned payment gateway and that transactions have a transaction ID.

Error Inserting Customer x: Customer Code is not unique

Seeing this error in the logs after Kashflow synchronisation indicates that the client's email address no longer matches the email address in Kashflow. To resolve this, update the client's email address in Kashflow to match it in WHMCS.
