How do I stop double entry between my CRM and my accounting software?
Decide which system each piece of data is entered in, enter it there once, and automate the copy. Typically client and job data is entered in the CRM, and an automation layer such as Make.com creates the invoice in QuickBooks, Xero or Sage when the job reaches a billable status, then writes the invoice number back to the CRM.
In detail
Double entry happens when two systems both need the same data and nobody has decided which one owns it. The fix is less about the tools than about that decision, then an automation that enforces it.
The steps
- 1. Pick a system of record for each field
- Clients, scope, pricing and job status usually belong to the CRM. Invoices, payments and tax belong to accounting.
- 2. Define the trigger
- Choose the exact condition that means an invoice should exist, such as a status of Billable with every required field complete.
- 3. Validate before you post
- The automation checks that required fields are filled and figures add up, and stops with an alert if they do not.
- 4. Prevent duplicates
- Record the accounting ID on the CRM item so a repeated trigger updates the existing invoice instead of creating a second one.
- 5. Write back
- Send the invoice number and status back to the CRM so the team never has to open the accounting system to check.
Example
PCMGKC structured all client, scope, pricing and billable items in monday.com. Make.com pulls the job data, validates the financial inputs, creates the invoice in QuickBooks, blocks duplicates and writes the invoice ID back to monday.com. Manual invoice processing time fell by 70 to 85%, and billing now happens the moment a job reaches billable status.
