10 Questions to Ask an Accountant Before Choosing One

Quick answer. Before signing with an accountant, validate 10 key criteria: sector specialization, dedicated contact person, accounting software used, exact scope of the engagement letter, fee structure and rates, financial statement delivery timelines, proactive tax and HR advice, professional indemnity insurance, data portability, and mandatory registration on the Order's roster.

In 2026, compliance demands have intensified. Digital reporting (DSN, e-invoicing, e-reporting from 2027), updated professional standards, CSG changes, and VAT updates require a competent accounting partner. Choosing based on price or word-of-mouth without validating fundamentals risks costly surprises: missing contacts during critical moments, unsuitable software, hidden costs, missed deadlines, or inadequate insurance coverage.

This guide outlines 10 non-negotiable questions to ask during interviews before signing any engagement.

1. Are you registered on the Order's professional roster?#

Why ask it: Only registration on the Order's tableau—governed by Ordinance No. 45-2138—grants the legal right to practice and use the professional title. It's your legal guarantee that you're not dealing with an unqualified bookkeeper or an unregistered salaried employee.

Expected answer: The accountant should show you their registration by checking the official directory at www.experts-comptables.fr, which is public. They should provide their registration number and regional council name.

Red flag: Hesitation, vague response, refusal to verify in real time, or "Yes, but renewal is pending." Only active registration counts.

2. What is your sector specialization?#

Why ask it: Accounting, tax, and HR rules vary significantly by sector: hospitality (restaurants, hotels), liberal professions (lawyers, doctors, architects), construction, e-commerce, real estate, or tech startups. A generalist accountant who accepts all sectors equals mediocre advice risk.

Expected answer: The accountant names sectors where they have solid portfolio depth and recognized expertise. They specify % of clients per sector, years of experience in each, and ongoing training (e.g., updated hospitality standards, 2026 furnished rental micro-BIC rules).

Red flag: "We work with everyone" or lack of concrete details on clients. No verifiable references in your sector.

3. Who will be my dedicated contact, and what's their experience level?#

Why ask it: Behind a firm is a person. If that contact changes every six months, or if it's an unsupervised junior, you risk delays, oversights, and loss of continuity.

Expected answer: Full name, qualifications (diploma, years of experience, specializations). Real availability (office hours, guaranteed response time). Who backs them up during absences? Who makes complex decisions?

Red flag: No named contact, or frequent turnover. Large firms (50+ staff) offering you a "queue" instead of a person.

4. What accounting software do you use, and can I access my data in real time?#

Why ask it: Pennylane, MyUnisoft, Sage, Cegid, TiiM, or Yooz: options vary. Some offer real-time client access; others don't. Some interfaces are user-friendly; others are highly technical. Can the firm manage your payroll software? Can they export your data if you leave?

Expected answer: Specific software name, version, last update date. Client access: document portfolio, draft financial statements before validation, unpaid invoice tracking. Data portability: can data be exported in standard format (Excel, CSV)? Is there a notice period? Any export costs?

Red flag: Refusal to export data, obsolete software (Excel-based solutions in 2026), excessive "termination fee," or software imposed without comparison.

5. What does your engagement letter cover, and what's charged separately?#

Why ask it: The engagement letter—mandatory under the professional Code of Ethics—must specify exactly who does what. Too many accountants use vague letters, then bill you later for unlisted services (consolidated balance sheet, profitability analysis, loan documentation, advisory, tax opinions on unusual transactions).

Expected answer: Copy of the engagement letter before signing. It must list: journal entries, centralizations, opening/closing entries, tax return preparation, payroll reporting (DSN), VAT declarations, routine tax advice, HR compliance. Everything beyond scope must be optional with stated fees.

Red flag: Refusal to show the letter before signing, generic or undated letter, no firm signature. Hidden or vague option pricing.

6. How are your fees structured: flat fee, hourly, or per-item?#

Why ask it: Fee structure drives your budget and creates hidden incentives. A fixed annual flat fee is predictable; hourly billing can spike on complex years; per-item pricing (financial statements, payroll reports) creates disputes if extra items emerge.

Expected answer: Clear structure: fixed €/year, or €/hour with cap, or scaled (€ for SMEs, €€ for growth SMEs). Inclusions: number of payroll reports, VAT declarations, monthly reviews. Transparent add-ons (external audit, internal audit, contract updates, ad-hoc advice).

Red flag: Vague quotes lacking detail on inclusions, hourly billing without estimated time, or refusal to give annual ballpark estimates.

7. What's your timeline for delivering financial statements and tax returns?#

Why ask it: Legally, you must file tax returns within a deadline (e.g., three months after fiscal year-end). Exceeding it triggers penalties. A firm delivering statements in June for a December 31 year-end is dangerous.

Expected answer: Guaranteed timeline (e.g., "Statements in February for December 31 close; tax returns in March"). Document submission process: who sends what to whom and when? Who signs final tax filings (you or the firm)?

Red flag: No committed timeline, "rush" premium fees, documented late deliveries for other clients.

8. Do you provide proactive tax and HR strategy advice?#

Why ask it: Executing payroll and filings is table stakes. A true accounting firm advises on tax optimization (corporate vs. individual structure, salary vs. dividends), restructuring (holding companies, real-estate SPVs, partnerships), director compensation planning, reserve strategies, and VAT management.

Expected answer: The accountant names specific projects or themes: associate current account optimization, director salary planning, exit/succession strategy, 2026 CSG/PFU impact on dividends, VAT audit risk assessment.

Red flag: "We handle compliance only" or "Advisory isn't our specialty." No proactive updates after regulatory changes.

9. How does data retrieval work if I end the relationship?#

Why ask it: Transitions happen. You must easily access historical documents (journals, ledgers, draft statements), archived payroll records, and vendor/customer/employee data without excessive fees or long delays.

Expected answer: Online access to a secure portal (Pennylane and MyUnisoft both offer data export) or USB/external drive delivery. Maximum retrieval timeline (e.g., "15 days"). Standard format (no proprietary locks). Stated cost (ideally free, max one invoice).

Red flag: Data access conditional on notice period length (e.g., 6-month notice), excessive retrieval fees, or data locked in incompatible proprietary systems.

10. Do you hold current Professional Indemnity Insurance?#

Why ask it: Accountants can make errors (incorrect director salary, missed tax deduction, late filing triggering penalties). Professional indemnity insurance protects you if the firm causes financial harm. It's a fundamental legal safeguard.

Expected answer: Yes, active professional indemnity insurance with policy dates. Coverage amount (minimum €1M for general practices). Insurer name. Ideally, an insurance certificate provided before engagement letter signature.

Red flag: No insurance, lapsed coverage, refusal to share the certificate, or deductible so high it's practically useless (e.g., €50,000 deductible).

Sole proprietor / Freelancer: Verify the firm handles VAT thresholds well (€37,500 / €85,000 in 2026) and doesn't over-complicate obligations. Request full-scope coverage (simplified accounts, tax filing, VAT if threshold exceeded).

Liberal profession: Specialization is critical (lawyers ≠ doctors ≠ architects in tax rules). Ask for expertise on retirement provisions, accrual-basis accounting, and deductible expenses.

Partnership / Limited company: Advice on optimal compensation (salary vs. dividends, 2026 CSG/PFU impact), reduced corporate rate (€42,500 threshold), minority partner social contributions.

Startup / Early-stage business: Request experience with funding rounds, feasibility audits, subsidy/tax credit management (R&D credit, innovation credit), and rapid-growth support.

• E-invoicing mandatory 2025/2026: Does the firm handle Chorus Pro or partner platforms?
• E-reporting DSN: Can they manage real-time DSN uploads and error corrections?
• New quality management standard (January 2025): Is the firm compliant with the updated professional standard? It's a regulatory obligation.
• AML identity verification: Must the firm verify beneficial owners before engagement? Yes—it's a legal requirement (anti-money-laundering professional standards, NPLAB).
• Response time expectations: Post-2024 deadlines are tighter. Ask for maximum response timelines.

At Hayot Expertise, we've seen firms damaged by poor accountant choices: an industrial SME penalized by an overextended contact missing quarterly payroll filings, a freelancer billed for "advisory" work with zero justification, a startup losing data access without exit procedures. All three cases had one thing in common: the right questions weren't asked upfront.

Choosing an accountant isn't passive "we'll see how it goes"—it's active due diligence. You must validate that the partner understands your situation, that the relationship rests on clear rules (specific engagement letter, transparent fees), and that you're legally protected (Order registration, professional indemnity, 2026 quality standard compliance).

The difference between a strong firm and a mediocre one often lies in clarity of expectations and relationship maturity from day one. These 10 questions structure exactly that.

Hayot Expertise recommendation. Before signing, create a comparison scorecard for your top 3–4 firms: rating each answer (yes/no/partial), estimated annual fees, statement timelines, software used. Request sector references if possible. Having an external advisor (lawyer, second accountant) review the engagement letter is well worth the cost. Finally, negotiate a short exit notice period (e.g., 3 months) to preserve flexibility.
