PAPER TRAIL

A scan, a photo and a handwritten form. PAPER TRAIL is an original Brightwork demonstration. A scanned tax invoice, a phone photo of a till receipt and a handwritten expense claim, read by the same local model through its own vision encoder and turned into structured data a bookkeeping system can import.

PTA · A scanned tax invoiceFictional source

Scanned tax invoice from Kiln Timber Supplies to Avery Joinery, total $1,628.44.

PT1 · The invoice, as dataQwen3.8-27B

Checked by Brightwork · 2 corrections

Two characters misread: the account number has nine zeros where the invoice shows eight, and the footnote’s “lineal metres” became “linear metres”.
The note asking to confirm the 2026 dates is unnecessary: they are this year’s.

Notes from the model

Footnote on invoice: 'Timber is supplied in random lengths; linear metres are rounded to the nearest 0.5.'
Account reference printed on invoice: AVJ01 (not captured in a dedicated field).
Verify banking details before payment: BSB 000-000 and Account 000000000 appear to be placeholder/zero values.
Verify ABN: 00 000 000 051 also looks like a placeholder value.
Invoice and due dates are in 2026 (28/08/2026 and 27/09/2026) as printed; confirm these are correct.
Arithmetic check: line items sum to 1480.40, GST 10% is 148.04, total 1628.44 - all consistent with the printed figures.

The prompt

This is a scanned supplier invoice. Read it for our bookkeeping. Return one JSON object with these fields: document_type, issuer, issuer_abn, document_number, date (YYYY-MM-DD), due_date (YYYY-MM-DD or null), bill_to, line_items (each with description, quantity, unit, unit_price, amount), subtotal_ex_gst, gst, total_inc_gst, payment (method and details as printed), and notes (anything unclear, missing or that a bookkeeper should check). Use null when something is not on the document. Write numbers as plain numbers. Return only the JSON.

Then the source document, after a standing instruction to use only the material provided and never invent names, figures, dates or rules.

Notes from the model

No customer / bill-to name printed. Document number is the till transaction reference (TRANS 4471); no separate invoice number is shown. Subtotal ex GST is not printed on the receipt and was calculated as total less GST (1211.55 - 110.14 = 1101.41). No due date present, consistent with point-of-sale payment. ABN is printed as 00 000 000 078 (zeroed pattern) - bookkeeper should verify the supplier's actual ABN before claiming input tax. Operator 'KIM' and 'REG 2' also printed. Item count shown as 58.

Notes from the model

The APPROVED BY field is blank. The claim is signed (B. Tran) but has not been approved.
The 09/10/26 item lists 78 km but no amount. The form states mileage is paid at the ATO cents-per-kilometre rate, so this must be worked out before paying. The on-form total of 108.00 only adds the parking (12.00) and lunch (96.00) lines and does not include the mileage.
The form requires a tax invoice or receipt for every item. Receipts are not visible on this scan, so confirm they are attached (in particular for the 96.00 lunch and the parking).
The venue on the 09/10/26 line is handwritten as 'Kookaburra Ck'; confirm the intended name.
Claim date 14/10/2026 is within 30 days of the expense dates (07-09/10/2026), so the older-than-30-days rule (Priya's approval) does not apply on age grounds.
