Two models, two demands
The business accounting market has split since 2015 into two universes. The first, In Extenso and generalist firms, serves SMEs seeking a support partner. The second, Pennylane, serves those seeking smooth and inexpensive accounting execution.
Neither supplants the other. They do not play the same game.
In Extenso: the partner who anticipates your growth
In Extenso, founded in 1991 by former Deloitte partners, is France’s leader in generalist SME consulting. Its model rests on physical presence in 250 local offices and a dedicated advisor who masters accounting, tax, payroll, employment law, legal advice, financing and business transfer.
The key advantage lies in integration. When you ask about optimal manager compensation (salary vs. dividends), the advisor arbitrates at once the tax impact, social security coverage, payroll cost and balance sheet effect. A single partner thinking transversally, not software recording flows.
In Extenso also excels when you consider a structural milestone: transfer, growth financing, team restructuring, complex legal structure. These challenges require a 360-degree vision that only a partner who knows your complete file can provide.
Average cost for a 30K€ revenue SME ranges around 2,500 to 4,500 euros annually at In Extenso, depending on complexity and staff size. This is an investment that pays off as soon as you decide on major hiring, financing or transfer.
Drawback: less automation on pure accounting flow. If you seek smooth bank reconciliation and automatic document generation, Pennylane performs better.
Pennylane: accounting automation and transparency
Pennylane is a SaaS platform you access in 48 hours. It centralizes digital accounting, outsourced payroll, invoicing and bank connectors to automate your accounting flow and reduce manual entry.
The advantages are immediate. Price: 500 to 2,000 euros annually depending on modules chosen, four to five times cheaper than In Extenso. Automation: smooth bank connectors, auto reconciliation of entries, document generation. User-friendly interface, designed for owners, not accountants. Pricing transparency: the price is identical for everyone, no negotiation or bespoke quotes.
Pennylane is perfect if your SME runs in regular management mode, you master your accounting and your challenges remain “standard”: accounting, payroll, invoicing, routine filings.
The drawback lies in the absence of a dedicated advisor. If you ask about tax optimization of your compensation structure, chat support will point you to an FAQ, not to an answer tailored to your situation. Pennylane’s “transactional” model, where each module stands alone, does not replace the cross-functional arbitration of an advisor who has known your file for three years.
Pennylane tires quickly when there is a strategic challenge: transfer, major financing, organizational transformation, or even a simple question about optimal dividend taxation.
Direct comparison: three scenarios
Scenario 1. Stable SME, 2-5 employees, solid accounting mastery
You pilot your activity well, your needs are accounting and payroll. Tight budget. Verdict: Pennylane suffices. You save 1,500 to 2,000 euros yearly by remaining master of your management. Limitation: if a complex question arises (payroll restructuring, major investment, planned transfer), you must seek external advice, costing hourly rates.
Scenario 2. Growing SME, 5-20 employees, multiple challenges
You are hiring, investing, considering expansion. You need proactive advice on tax, payroll, legal structure, financing. Verdict: In Extenso. The premium (about 2,000 euros compared to Pennylane) pays for itself immediately once you decide on a loan, hiring or payroll restructuring. A dedicated advisor justifies this premium.
Scenario 3. SME facing structural challenge (transfer, major financing, transformation)
You are preparing a transfer in 3-5 years, seeking to finance an acquisition, or reorganizing the management team. Verdict: In Extenso is essential. You need a partner mastering all angles (tax, social, legal, financing) who can support you over several years. Pennylane covers accounting only, not strategy.
