Finance
Find the discrepancy between related financial documents.
Revised invoices, credit notes and statements should tell one consistent story. DocGlue shows where they do not.
The problem
Small changes, large consequences.
A revised invoice changes one tax figure. A credit note does not quite offset the original. A statement lists a balance that matches none of the documents behind it.
Finding the specific number that changed usually means printing both documents and reading them side by side.
Documents this covers
- Invoices and revised invoices
- Credit notes
- Statements
- Receipts
- Contracts with payment schedules
The DocGlue workflow
From two PDFs to a decision.
- 01
Upload two related documents
An invoice and its revision, an invoice and a credit note, or two statements.
- 02
Figures are extracted
References, dates, due dates, payment terms, subtotal, tax and total, each with its page.
- 03
Values are compared
Amounts are compared in the detected currency. Mixed currencies are flagged and never subtracted.
- 04
Record the outcome
Export the findings as CSV or a PDF report for your working papers.
The result

What you get

Invoice 1 vs invoice 2
Upload two PDFs, or try the Cedar Peak sample. Put the document you agreed to first (a quote, an order, or the earlier version) and the one you are checking second. Differences show what changed in the second one. If a quote and an invoice are the wrong way round, DocGlue swaps them and tells you. Text you can select is read as written; a scanned page is read only when it has no selectable text.
Auto reads symbols such as R, $, EUR, GBP, CAD, and AUD. Pick a currency when an amount has no symbol. If the two PDFs clearly use different currencies, the report warns you and does not subtract them.
Try sample pair loads a Cedar Peak quote and invoice, then runs the same comparison as an upload. Nothing is saved.
Waiting for two PDFs
Add the Invoice 1 and the Invoice 2. Results list matched fields, differences, missing lines, and uncertain matches.
FAQ
Finance questions.
Is DocGlue an accounting system?
No. It compares documents and reports differences. It does not post entries or replace your ledger.
Which currencies are supported?
USD, ZAR, EUR, GBP, CAD and AUD are detected automatically, and you can choose one when amounts have no symbol.
Is my financial data stored?
No. Files are processed in memory and discarded when the request finishes.
More solutions
Procurement
The lowest total is not always the cheapest quote. DocGlue lines up what each supplier actually included, so you choose on scope, not on the bottom line alone.
Accounts payable
Before an invoice is approved, DocGlue compares it with the quote or purchase order and lists every line, quantity, price and total that does not match.
Construction
Projects change. DocGlue shows exactly what changed between the quote, the variation and the invoice, so scope creep is a decision, not a surprise.
Stop comparing documents line by line.
