Creating invoice numbers manually is slow and error-prone — especially when managing many sales. ConnectBooks can now generate invoice numbers for you automatically.
How It Works
ConnectBooks auto-fills the invoice number each time you create a new invoice, incrementing by one from wherever you left off.
The default sequence starts at 1001:
1001 → 1002 → 1003 → and so on
You can also use a custom format:
INV100 → INV101 → INV102
SALE1 → SALE2 → SALE3
The system simply continues from the last invoice number used. If you manually enter INV109, the next auto-generated number will be INV110.
How to Enable It
Go to Stores & Files → Inventory Files → File Settings.
In the left panel, click Purchasing & Vendors.
Click the Custom Invoice Number field and enter your desired starting number or format — e.g.,
1001,INV500,SALE1.Click Save.
Every new invoice will follow the pattern automatically from that point forward.
