Outsourced Administrative & Accounting Management in Paris

In short. Outsourcing your administrative and accounting management means handing your back-office (invoicing, collections, bank reconciliation, VAT and DSN filings) to a chartered-accountancy firm while keeping control of the steering. For a Paris SME, it is usually more flexible and cheaper than a full-time administrative hire.

Picture your week without the stack of unprocessed supplier invoices, without the client chase-up emails you keep postponing, without the stress of the monthly VAT return due on the 24th, and without the payslips to verify before the bank run. This is what outsourced administrative and accounting management delivers in practice to Paris SME founders and managers: the freedom to focus on your business while a specialist team handles the daily operational mechanics with the same rigour as an in-house finance department — at a fraction of the cost.

Hayot Expertise, at 58 rue de Monceau, Paris 8, offers a fully outsourced administrative and accounting management service calibrated for companies with 5–50 employees whose activity volume does not yet justify a full-time internal hire, or whose management team prefers the quality and continuity of professional outsourcing over the HR complexity of an internal recruitment.

Before proposing a solution, let us quantify the problem. Research by IFOP in 2025 found that French SME founders spend an average of 11 hours per week on administrative tasks — nearly 30% of their working time. This time goes to processing administrative emails, completing regulatory forms, chasing unpaid invoices, preparing documents for the accountant and responding to tax or social security requests. At a founder's hourly value of €50–€100, this translates to an annual economic loss of €28,000–€55,000 in diverted attention.

Administrative errors carry direct costs too. A late VAT payment triggers a 5% surcharge (French Tax Code, art. 1731) plus late-payment interest of 0.20% per month (art. 1727). A late DSN filing costs €7.50 per employee per month of delay (the DADS was abolished in 2017 and replaced by the DSN). A missed supplier payment loses an early-payment discount of 2-3%. Over 12 months, these cumulative costs frequently exceed the fee for a complete outsourcing service, making the business case straightforward.

Client Invoicing and Collections Management#

Invoicing is the first task founders outsource — and one of the most impactful. Our service covers:

• Invoice preparation and dispatch to your specifications: PDF, structured Factur-X format (mandatory for B2B e-invoicing from 2026), or transmission through your approved dematerialisation platform (PDP)
• Accounts receivable monitoring: weekly dashboard of outstanding invoices by age and amount, with alerts on overdue balances
• Structured collection process: friendly reminder at D+10 past due, firm follow-up at D+30, formal notice at D+45, coordination with a debt collection firm or lawyer for disputed amounts
• Cash matching: daily reconciliation of incoming bank transfers against open invoices
• Credit note management: issuing and allocating credit notes for returns, disputes and commercial adjustments

Purchase and Supplier Management#

• Supplier invoice receipt and processing: dematerialisation via Dext, mandatory legal information check, amount and VAT code validation
• Three-way matching (purchase order / delivery receipt / invoice) for companies with recurring procurement flows
• Payment scheduling: sequencing payments against contractual terms and cash position, optimising the days-payable-outstanding (DPO) without damaging supplier relationships
• Expense claim management: collection via Dext or Expensya, fiscal compliance check (recoverable VAT, deductibility of expense types), reimbursement to employees

Treasury Monitoring and Cash Forecasting#

Cash is the primary health indicator of any SME, yet fewer than 30% of French SME founders monitor it formally each week. Our treasury service includes:

• Daily bank reconciliation: every movement is categorised, matched and verified in real time within Pennylane
• Weekly cash dashboard: current balance, payments due this week and next, expected receipts, projected balance at D+7 and D+14
• 12-week rolling cash forecast: modelling inflows and outflows, identifying tension points before they become crises
• Overdraft alerts: automatic notification when the balance approaches a threshold you set
• Banking coordination: facility requests, scheduled payment batches, loan instalment tracking

Regulatory Filings — VAT, DSN, CFE#

We manage your entire compliance calendar:

• Monthly or quarterly VAT (CA3): collection of sales and purchase data, calculation of VAT due or recoverable credit, e-filing and e-payment via the DGFiP professional portal
• Monthly Nominative Social Declaration (DSN): transmission of payroll data to URSSAF, AGIRC-ARRCO pension funds, health insurance and disability insurers — with systematic data-consistency checks before submission
• CFE (local business tax): base verification, payment scheduling
• Annual tax return data preparation: collection and transmission of adjusted data to the chartered accountant for the annual liasse fiscale

Day-to-Day Bookkeeping#

• Bank transaction import and categorisation: automatic integration of bank statements into Pennylane, allocation to cost and revenue accounts in your chart of accounts
• Invoice processing: entry of purchase and sale invoices, third-party account (client/supplier) matching
• Fixed asset management: asset card creation, depreciation calculation (straight-line, reducing-balance, component method), fixed asset register maintenance
• Accrual entries: period-end provisions, accrued expenses, deferred income and prepaid charges

Monthly Management Reporting#

Every month, you receive a plain-language summary readable by any non-accountant:

• Monthly P&L and year-to-date cumulative result
• Revenue billed vs target and vs prior-year month
• Gross margin by service or product line
• Fixed vs variable cost analysis: variance against budget
• Available cash and 4-week projection
• Accounts receivable summary: total outstanding, overdue amount, top 5 debtors

Beyond the day-to-day execution, outsourcing your admin and accounting has one simple goal: that you never miss a deadline again. We keep a calendar of the obligations specific to your business and handle the filings:

• VAT: preparation and e-filing of the monthly or quarterly CA3 return, or the annual CA12 under the simplified real regime, with collected and deductible VAT checked before submission.
• DSN: the monthly nominative social declaration and event signals (joiners, leavers, sick leave) on time — in liaison with our payroll desk.
• CFE and CVAE: tracking of notices, instalments and deadlines; the CVAE only concerns businesses with more than €500,000 in turnover.
• Corporate-tax instalments: calculation and payment on the quarterly due dates (15 March, 15 June, 15 September, 15 December).
• E-invoicing: from 1 September 2026, mandatory receipt of invoices for all businesses via an approved platform (PDP); issuing follows the size-based schedule (large companies and mid-caps in 2026, SMEs and micro-businesses on 1 September 2027). See our dedicated e-invoicing 2026 page.
• End of the simplified VAT regime: under the 2025 Finance Act, the simplified regime (CA12) ends on 1 January 2027 in favour of monthly or quarterly real-regime filing. The 2026 VAT franchise thresholds remain €37,500 (services) and €85,000 (goods), independent of the micro-regime ceilings.

Every deadline triggers an alert and a check: you approve, we file. That regularity is what removes late-payment penalties and end-of-month stress.

• TPE/PME with 3–50 employees where the founder currently manages administrative and accounting tasks personally and wants to delegate without hiring
• Growth-stage startups that need a structured administrative function but are not yet ready for an in-house team
• Self-employed professionals (doctors, lawyers, architects, consultants) who want to focus entirely on their technical activity
• Associations and foundations where volunteers lack the expertise or bandwidth for routine accounting
• Companies in transition: departing administrative employee, ERP migration, organisational restructuring
