Good records are boring and extremely valuable. They are what you show a tax office, a lender or a client who disputes a bill. A small amount of tidiness each week saves a great deal of stress later.
What to keep
Keep everything that shows money coming in or going out:
- Copies of every invoice you send, and every credit note.
- Receipts for business costs, and bills you receive from suppliers.
- Bank statements and payment confirmations.
- Quotes, purchase orders and signed agreements.
- Mileage and timesheet records, if you charge for time or claim travel.
How long
The period depends on the country and the type of record, and is often several years. Tax authorities publish their requirements, so check the one that applies to you rather than relying on a rule of thumb. If in doubt, keep records longer than the minimum.
A simple system
One folder per year, and inside it folders for sales, costs and bank records. Name files with the date and a short description, such as 2026-03-12 Invoice 042 Acme. Save invoices as PDFs. A spreadsheet that lists each invoice with its amount, the date sent and the date paid shows at a glance what is outstanding.
Paper or digital
Digital copies are usually accepted if they are clear and complete. Photograph paper receipts as soon as you get them, because thermal paper fades. Our Photos to PDF tool at handyfiletools.com turns a stack of receipt photos into a single PDF without uploading anything.
Back up
Keep a second copy of your records in a different place: an external drive, or an encrypted cloud folder. A fire, a stolen laptop or a failed disk should not erase your business history.
Privacy of your records
Invoices contain names, addresses and bank details. Store them somewhere private, share them only with those who need them, and delete what you are not required to keep. Our tools work in your browser and do not upload your documents, but your saved files are your responsibility.
