Auto-splitting a Year of Invoices by Vendor

The PDFalot Team·March 22, 2026·4 min read

Accountants: use Smart Split to reconcile month-end faster and get every vendor into its own tidy PDF.

Every accountant has received it at some point: a single 400-page PDF with a year of invoices scanned in one go, in no particular order. Splitting that by hand is a full afternoon. Smart Split turns it into a coffee break.

The setup

Upload the combined PDF to the Split tool and choose AI Smart Split. The AI reads each page, groups pages that belong to the same invoice, and proposes a split boundary before each new document.

The reconciliation trick

Ask Chat with PDF: 'List every unique vendor name that appears, and for each one list the invoice numbers and totals.' You now have a reconciliation table you can paste straight into your accounting system, and each vendor's invoices sit in their own tidy split PDF.

What to double-check

  • Any invoice where the total on the last page didn't match your ledger.
  • Foreign-currency invoices where the exchange rate matters.
  • Credit notes — the AI marks them, but a human should confirm the sign.
