Bookkeeping basics for small businesses in France
Why bookkeeping matters for small businesses in France
Bookkeeping is the systematic recording of every financial transaction your business makes. In France, it is far more than an administrative chore: accurate books are the foundation for filing your tax returns, declaring VAT, paying social contributions and, if needed, proving your figures to the tax authorities (the administration fiscale) during a control. Without organised records, you risk late filings, penalties and cash-flow surprises. Good bookkeeping also gives you a clear view of your margins, your outstanding invoices and whether the business is actually profitable. For a sole trader or a small company, this visibility can be the difference between reacting too late and making informed decisions. Consider a small café owner who records sales daily and reconciles the till each evening: at any moment they know whether takings cover rent, supplier bills and payroll. Compare that to a freelancer who keeps receipts in a shoebox and scrambles once a year. The first has control; the second faces stress, guesswork and often a higher accountant's bill. Beyond compliance, lenders and potential partners will ask for financial statements, and only clean books can produce them. Treat bookkeeping as ongoing business intelligence rather than a task you dread each quarter.
Legal bookkeeping obligations by business structure
Your bookkeeping duties in France depend heavily on your legal structure and tax regime. A micro-entrepreneur has the lightest obligations: you must keep a chronological record of receipts (livre des recettes) and, for those selling goods, a register of purchases. You do not produce a full balance sheet, but you must retain supporting documents and issue compliant invoices. Sole traders and companies under the régime réel (simplified or normal) face fuller obligations: keeping a general ledger (grand livre), a journal recording transactions in date order, and producing annual accounts including a balance sheet (bilan), an income statement (compte de résultat) and explanatory notes. Companies such as SARL, SAS and EURL must also hold accounts that follow the Plan Comptable Général, the French chart of accounts standard. The régime you fall under is driven by your turnover and your activity type, and thresholds are revised periodically, so verify current figures before assuming your obligations. Whatever the structure, invoices must contain mandatory legal mentions such as your SIREN number, VAT number where applicable, and clear payment terms. Getting the structure-specific requirements right from the outset saves costly reclassification later.
Setting up your chart of accounts and record-keeping system
The chart of accounts (plan comptable) is the backbone of French bookkeeping. It organises every transaction into standardised account numbers grouped into classes: class 1 for capital, class 2 for fixed assets, class 3 for stock, class 4 for third parties (suppliers, customers, tax and social bodies), class 5 for financial accounts such as bank and cash, class 6 for expenses and class 7 for income. Using the correct account codes means your accounting software can automatically generate the ledgers and statements the authorities expect. Start by adapting a standard chart to your activity: a consultant needs far fewer accounts than a retailer with inventory. Keep it simple; you can always add sub-accounts as the business grows. Alongside the chart, decide how records will flow. Set up a dedicated business bank account so personal and professional transactions never mix, which is a legal expectation for companies and strongly advised for sole traders. Establish a routine for capturing receipts, ideally digitising them as they arrive, and a folder structure that mirrors your accounting periods. A consistent, well-designed system at the start prevents hours of untangling later and makes handover to an accountant painless.
Which documents and records you must keep (and for how long)
French law sets minimum retention periods, and keeping documents too briefly can leave you exposed during an audit or dispute. As a general rule, accounting records and supporting documents such as invoices, delivery notes and ledgers must be kept for ten years. Commercial contracts and correspondence relating to them are typically kept for five years. Documents linked to payroll, such as pay slips and employment contracts, follow their own rules and are generally retained for several years to cover social and tax verification periods. VAT-related documents should be kept in line with the ten-year accounting rule to be safe. Both original paper and digital copies are acceptable provided digital documents are stored in a way that guarantees their integrity and readability over time. Never discard a document simply because the transaction is closed; the retention clock often runs from the end of the relevant accounting or tax year. The table below summarises common categories, but always check the current period for your specific situation, as rules evolve. A reliable archiving habit, whether a labelled physical binder per year or a secure cloud folder, ensures you can produce any record quickly when asked.
Recording income, expenses and VAT day to day
Consistent daily or weekly recording is what keeps bookkeeping manageable. For income, log every sale or invoice as it is issued, noting the date, client, net amount, VAT rate applied and total. For expenses, record each purchase with its supplier, category, net amount and recoverable VAT, attaching the justificatif (the receipt or invoice). If you are subject to VAT, you must track output VAT collected on sales and input VAT paid on purchases, since the difference is what you declare and pay. Micro-entrepreneurs under the VAT exemption (franchise en base) do not charge or reclaim VAT and simply record gross amounts, but must monitor turnover against the exemption thresholds. Reconcile your records against your bank statement regularly; matching each line ensures nothing is missed or double-counted. For example, a freelance graphic designer might set aside thirty minutes every Friday to enter the week's invoices and expenses, then reconcile once a month. This rhythm prevents a year-end backlog and keeps VAT declarations accurate. Pay attention to mixed-use expenses, such as a phone used for both business and personal purposes, where only the professional portion is deductible.
Choosing between manual, software or an accountant
There is no single right answer; the best choice depends on your activity, volume of transactions and comfort with numbers. Manual bookkeeping, using a spreadsheet or a paper ledger, can suit a micro-entrepreneur with few transactions and simple obligations, and it costs little. However, it is error-prone and offers no automation as you grow. Accounting software is the middle ground for most small businesses: it applies the correct account codes, calculates VAT, generates ledgers and statements, and often connects to your bank to import transactions automatically. Many tools are designed specifically for French requirements and formats. An expert-comptable (chartered accountant) brings professional oversight: they can prepare and certify annual accounts, advise on tax optimisation within the law, and represent you if the authorities have questions. Companies often combine software for daily entry with an accountant for year-end and advice, which balances cost and reassurance. When deciding, weigh the time you would spend doing it yourself against the risk of errors and the value of expert guidance. As turnover and complexity rise, most owners find that professional support pays for itself in avoided mistakes and time saved.
Common bookkeeping mistakes and how to avoid them
Certain errors appear again and again among small businesses. The most frequent is mixing personal and business finances, which makes reconciliation a nightmare and can raise questions during a control; a dedicated business account solves this. Another is falling behind, letting receipts pile up until the deadline looms, which leads to rushed, inaccurate entries. Setting a fixed weekly slot prevents this. Losing or discarding supporting documents is equally damaging, because without a justificatif an expense may be rejected as deductible; digitising receipts immediately protects you. Applying the wrong VAT rate or forgetting to track input VAT costs real money over time, so double-check rates for each category. Misclassifying transactions into the wrong account distorts your statements and can misstate profit; using software with clear categories reduces this risk. Finally, ignoring turnover thresholds can push a micro-entrepreneur unexpectedly into VAT obligations or a different regime without preparation. Monitor your cumulative figures throughout the year. Most of these mistakes stem from a lack of routine rather than a lack of knowledge, so the antidote is a simple, repeatable process combined with occasional professional review.

How long must I keep my accounting documents? As a general rule, accounting records and supporting documents such as invoices and ledgers are kept for ten years. Commercial contracts are typically kept for five years, and payroll records for several years. Always check the current period for your specific situation, as rules can change.
Do I need an accountant or can I use software? It depends on your volume and complexity. A micro-entrepreneur with few transactions may manage with software or even a spreadsheet. As turnover and obligations grow, many owners combine accounting software for daily entry with an expert-comptable for year-end accounts and advice.
Can I keep my records digitally instead of on paper? Yes. Digital copies are acceptable in France provided they are stored in a way that guarantees their integrity and readability throughout the retention period. Many businesses digitise receipts as they arrive to avoid losing paper documents and to simplify archiving.
