TL;DR
What did u/Typical_Tie_4947 use Claude for?
A service business owner connected Claude to Jobber through the API so it creates the first draft of each invoice under custom merge and split rules the CRM lacked. They got invoice rules their CRM didn't offer and more control over when invoices are created.
What they did
They use Jobber as their CRM and QuickBooks for finances, with Jobber syncing invoices to QuickBooks. Claude creates the initial invoices in Jobber through an API connection running on a droplet, applying custom rules for merging and splitting invoices and controlling what triggers an invoice.
How it went
They got invoice rules their CRM didn't offer and more control over when invoices are created.
Worth knowing
- Every invoice is still sent by hand from QuickBooks, and they say, "I would never advise having Claude do the actual sending." Other commenters in the thread warned against building your own invoicing software.
- Price check: Claude: free plan; Pro: US$20/month, or US$17/month on a yearly plan (US$200/year) (checked Nov 1, 2026).
