In short

Give each client one folder, then a folder per year and per period (month or quarter), split into purchases, sales, bank and payroll.Name every file date first, then issuer, type and amount: “2026-09-14 Swisscom Invoice 89.00 CHF.pdf”. Keep one intake folder per client for what hasn’t been checked, write the rule on one page for staff and clients, and keep records for the legal period: ten years in Switzerland and France, six in Spain. Kempt writes date-first names from each document’s content on a Mac.

Without any app

  1. One folder per client, then year and period

    Client › 2026 › 09 (or Q3) › Purchases, Sales, Bank, Payroll. A fixed tree means anyone in the firm finds a document without asking who filed it.

  2. Name every file date first

    Year-month-day, then issuer, document type and amount: “2026-09-14 Swisscom Invoice 89.00 CHF.pdf”. Files then sort by date in every folder, and a search for the supplier or the amount finds them. Write months with two digits.

  3. Keep an intake folder

    Each client gets an “Inbox” folder for what arrived but isn’t checked. Nothing is filed straight from Downloads or an email attachment, so nothing is filed twice or lost.

  4. Write the rule down

    One page: the folder tree, the naming pattern with three examples, and what clients should send each month. Share it with staff and clients; it saves more time than any tool.

  5. Keep what the law asks

    Switzerland: ten years for books and accounting records (CO art. 958f), electronic copies allowed. France: ten years (Code de commerce L123-22). Spain: six years (Código de Comercio art. 30). Keep e-invoices in their original format.

Questions people ask

What is a good naming convention for accounting documents?

Date first (YYYY-MM-DD), then issuer, document type and amount: “2026-09-14 Swisscom Invoice 89.00 CHF.pdf”. Files sort by date and the supplier or amount is searchable.

How should an accounting firm organize client files?

One folder per client, then per year and period, split into purchases, sales, bank and payroll, with an intake folder for what isn’t checked yet.

Should file names include the amount?

It helps: you can match a bank line to its document without opening it. Use a dot or comma consistently and add the currency.

Can accounting records be kept only as scans?

In Switzerland, yes for most records, if they stay complete and readable (CO art. 958f). In France, a reliable electronic copy is accepted under conditions. Check your firm’s rules for originals that must stay on paper.
