A month of invoices, one file, numbered.
Accountants ask for one PDF, numbered, with the totals page first. Producing that from a folder of downloads is the job nobody budgets time for.
For bookkeepers, finance assistants and anyone closing a month.
Why it usually goes wrong.
Two constraints shape the work: the page numbers in the bundle must match the reference on the summary, and a supplier query must be answerable without re-sending the whole file.
So: merge, number, and keep the ability to split one supplier back out. Numbering after splitting produces two documents with conflicting page numbers.
In this order
Every step runs in the tab
Merge the month
Drag the invoices into date order. The originals are not modified; the bundle is a new document.
Open Merge PDFNumber the bundle
Real text, starting wherever the summary says. Numbers are searchable, so a query about page 214 can be answered by opening the file and typing.
Open Page numbersPull one supplier back out
Type the page range and download it as its own file. The bundle stays intact.
Open Split PDFMark a draft before it circulates
A faint "DRAFT" as real text is sharp at any zoom and adds almost nothing to the file size. Useful when the numbers are not final.
Open Watermark PDF
- This does not read the numbers out of the invoices. There is no extraction to CSV, no totals and no reconciliation — the figures come from your ledger, not from this page.
- Encryption and password removal are not supported; both need a native PDF library rather than the browser.
- A scanned invoice with no text layer cannot be searched after merging. OCR lives in the contract scanner and reads page images; it does not repair the PDF.
- Large batches are processed in chunks because the tab holds every page of a batch at once.
