Archive a Year of Invoices

A year of invoices rarely arrives as a tidy set of files. It arrives as bank statements, vendor portals zips, and one or more bundled PDFs where every invoice is a page inside a single document. The archive job is to make that pile usable: every statement becomes a spreadsheet, every page carries a traceable number, and each invoice stands on its own.

The Job, in Order

1. Turn statements into spreadsheets. convert PDF to Excel — in your browser, free — takes each statement’s rows into a spreadsheet you can sort, total, and reconcile. Do this before anything else: the numbers are why you kept the statements.

2. Stamp a traceable number across the packet. add Bates numbering to a PDF — in your browser, free — applies a sequential identifier to every page of the bundle. In an audit or a dispute, that is what makes “the invoice from March” a page someone can point to instead of a claim someone has to take on trust.

3. Split the bundle at each invoice boundary. split a PDF by text — in your browser, free — cuts the bundled PDF wherever a marker appears: an invoice number, a date line, a vendor name header. Each invoice becomes its own file, named and findable.

4. Keep the copies that have to last in the archival format. For the set you retain long-term, convert a PDF to PDF/A — in your browser, free. PDF/A is the ISO standard for long-term preservation, and the format an archive should be stored in.

Verify the Archive

Open one converted spreadsheet and spot-check the totals against the source statement. Open two split files and confirm each contains exactly one invoice, start to end. Walk the Bates sequence on a few pages and confirm it is unbroken. An archive is only as good as the first time someone looks something up in it.

Frequently Asked Questions

What if the bundle has no consistent text marker at the invoice boundaries? Some bundles do not — mixed vendors, scans without a stable header. Then split a PDF by page ranges is the honest fallback: it takes a few minutes of attention, and the scan-quality guide covers what to do when the bundle is also image-heavy.

Do I need to upload a year of invoices anywhere? No. Every step above runs in your browser — no account, no upload, and the files never leave your machine. That matters more with a year of financial history than with a single file.

How big a bundle can the browser path handle? The browser path is bounded by your device’s memory, and very large bundles are where people hit it. The file size and quota limits page states the current ceilings for the local and cloud paths, and split a PDF is the standard way to bring a heavy file back inside them.

A year of invoices becomes an archive when three things are true: the numbers are in a spreadsheet you can total, every page carries a number someone can cite, and every invoice is its own file. All three steps run in your browser — which, for a year of financial documents, is the point.

Do It Directly

Ready to archive the pile in front of you? convert PDF to Excel the statements, add Bates numbering to a PDF the bundle, and split a PDF by text at each invoice boundary — all in your browser, free, with nothing uploaded. For the copies you keep, convert a PDF to PDF/A so the archive stays readable long-term.
