BY NUMBER7 AIMulti-invoice PDF processing · difficult invoice documents
One PDF can contain several bills.
Separate vendor invoices, keep continuation pages together and preserve credit notes as distinct records. Then validate, code and review each accounting outcome.
source pages
The buyer answer
How should multi-invoice and difficult PDFs be automated?
Resolve the document boundaries before extraction and coding. Keep each invoice’s pages, vendor and line items together; preserve the original source references. Materially uncertain page boundaries, unreadable values and conflicting evidence go to review rather than being silently filled.
Four-page source · exact worked boundaries
Four pages become two invoices and one credit note.
Choose an output to trace its pages
LAB-107 is one invoice on source page 1.
Pages 2–3 belong to one freight invoice. Keep the credit note separate and linked to its original invoice.
Continuation pages stay with the same bill
The freight invoice continues on page 3.
Westbridge Logistics’ LAB-108 spans source pages 2–3. Its line items continue on page 3, where the combined invoice total appears. Do not turn the continuation page into a new bill.
Open the two-page freight invoice| Source page | Description | Amount |
|---|---|---|
| 2 | Regional freight | $160 |
| 2 | Site transfer | $70 |
| 2 | Loading service | $35 |
| 3 | Final-mile delivery | $60 |
| 3 | Handling service | $23 |
Combined invoice total: $348. LAB-109 is a separate $48 credit referencing LAB-107, with a signed accounting amount of −$48.
The source determines the next step
Three inputs. Three explicit review conditions.
| Input | Supported outcome | Hold when |
|---|---|---|
| Mixed-vendor PDF | Separate document records with original page references | The invoice boundary remains ambiguous |
| Irregular line table | Supported quantities, unit prices and row amounts | Column meaning or a material value is unresolved |
| Poor scan or photo | Readable fields with their source evidence | The source cannot support a required claim |
Next step
Bring the documents your current stack avoids.
Start with a scoping call. Agree the representative mix and secure-transfer terms before sending documents; then record preparation, correction and final accounting work.
