If you freelance or run a small business, your paperwork rarely arrives in one tidy place. A design invoice lands as an email attachment, a hosting receipt is a screenshot, and the co-working space sends a PDF that looks nothing like the others. Come tax time, you are hunting through folders trying to reconstruct a year of spending from memory.
The fix is not fancy accounting software. It is a repeatable habit: once a month, gather everything, put it in order, stamp it with page numbers, shrink it, and lock it. Do that twelve times and your annual archive assembles itself. Here is how to build that routine using tools that run entirely in your browser, so your financial documents never leave your computer.
Collect everything for the month first
Before you touch any tool, pull every invoice and receipt for the month into a single folder on your computer. Save email attachments, download portal invoices, and export any receipts stuck in apps. If a receipt only exists as a photo, that is fine for now. The goal is one folder per month with every document present, so nothing gets discovered later after you have already closed the books.
- Client invoices you issued and any you received from contractors
- Subscription and software receipts (hosting, design apps, accounting fees)
- Travel, meals, and mileage receipts tied to work
- Bank or payment-processor statements for reconciliation
- One-off equipment or supply purchases
Put the documents in a sensible order, then merge
Order matters more than people expect. When your accountant or your future self opens the file, a logical sequence saves real time. A common approach is chronological by date, but grouping by category (income first, then expenses by type) also works well if your bookkeeping is category-driven. Decide on one convention and stick to it every month.
Once the pages are in order, use the Merge PDF tool to combine them into a single document. You can drag files into the order you want before combining, so the final PDF reads top to bottom exactly as you intend. Give the output a predictable name like 2026-03-expenses.pdf so your yearly folder sorts itself alphabetically into calendar order.
Add page numbers so nothing goes missing
A merged archive with thirty loose-looking pages is easy to lose track of. Running it through the Add Page Numbers tool gives every page a reference, so if someone says "the parking receipt on page 14 is unreadable," you both know exactly what they mean. Numbering also makes it obvious at a glance if a page was accidentally dropped during a later edit.
- Merge the month's documents into one PDF in your chosen order.
- Open that file in Add Page Numbers and place numbers in a corner, away from invoice content.
- Save the numbered version as your working copy for the month.
- Repeat monthly, then merge the twelve monthly files into one annual archive at year end.
Compress before you store or send
Scanned receipts and phone photos are the reason a simple expense file balloons to forty megabytes. Run the merged PDF through the Compress PDF tool before you archive or email it. Compression mainly targets the image-heavy pages, so your text-based invoices stay crisp while the bulky scans shrink. That keeps the file small enough to attach to an email to your accountant without hitting a size limit.
If a batch of receipts is still oversized, converting color scans to grayscale often helps, since receipts almost never need color to be legible. Aim for a file that is comfortably under any portal or email cap while remaining perfectly readable.
Lock the archive with a password
Your financial records contain client names, amounts, and sometimes bank details. Before you store the annual archive in cloud backup or email it, use the Protect PDF tool to add a password. Share that password through a separate channel from the file itself, and keep an unprotected master copy somewhere secure in case you forget it. That single step turns a sensitive pile of documents into something you can move around without worry.
None of this requires an account or uploads. The utility tools process your files in the browser, which matters a great deal when the documents in question are your business's entire financial paper trail.
