CassKai vs In Extenso: run it yourself, or delegate to a firm?

In Extenso is one of France's largest chartered-accounting networks, founded in 1991 in Lyon. It is not a software vendor: it is a firm (in fact a network of firms) employing thousands of chartered accountants and staff — on the order of 7,300 people across more than 280 agencies nationwide, serving over 170,000 clients. In Extenso offers a full range of services: bookkeeping, tax, social / payroll, legal, audit, advisory, wealth management, business transfer. To smooth the relationship, the group provides a collaborative client platform (historically "Inexweb", now often referred to as "In Extenso Online") to exchange documents and information, and even enter data online. In Extenso's central strength is human: a chartered accountant who knows your file, advises you, secures your filings and bears professional responsibility.

Key positioning point: comparing CassKai and In Extenso is not comparing two pieces of software — it is comparing two models. On one side, delegation to a firm (human support + platform). On the other, tooled autonomy: a SaaS you operate yourself. And crucially, the two are not mutually exclusive: many SMEs keep a chartered accountant for review, the balance sheet and certification, while running their day-to-day (invoicing, collections, cash) in a modern tool.

What this implies in 2026:

• Nature: In Extenso sells service + accompaniment (with a platform). CassKai sells a SaaS product you operate. In Extenso's cost is an engagement fee (a mission), not a comparable public software subscription.
• Autonomy: with a firm, part of the accounting work is done for you; with a standalone SaaS, you keep control and real-time visibility, without depending on back-and-forth.
• Geographic scope: In Extenso is very French (with a European presence). For Franco-African multi-standard operations (SYSCOHADA, UEMOA, Mobile Money), it is not its native ground.
• Human advice: this is a firm's real strength and what software, however good, does not replace 100% — expertise, judgement, engaged responsibility.

CassKai, published by Noutche Conseil (itself a chartered-accounting and advisory firm), is a standalone SaaS platform: multi-standard accounting (PCG, SYSCOHADA, IFRS, SCF), invoicing, France e-invoicing (PPF / PA) and UEMOA, cash management, payroll (15 countries), CRM and a GPT-4o AI assistant. We do not claim to replace a chartered accountant's judgement or engaged responsibility: we tool autonomy, and we fit very well alongside a firm (yours, or a partner), notably for Franco-African groups a 100%-France firm does not address natively.

Adopting CassKai when you work (or worked) with In Extenso can take two forms: complementarity (you keep your firm and add CassKai for control) or taking it in-house (you internalise the day-to-day). Here is the typical path, over 4 to 8 weeks:

1. Step 1 - Clarify the target model (week 1): decide what you keep with the chartered accountant (typically review, balance sheet, tax return package, certification) and what you bring into CassKai (invoicing, collections, cash, routine entry). Many SMEs do not leave their firm: they offload the day-to-day from it.
2. Step 2 - Data retrieval (weeks 2-3): ask In Extenso for the export of your general ledger, trial balance, sub-ledgers and FEC (you are entitled to it). CassKai's import wizard accepts these files and proposes mapping to the target chart of accounts (PCG, or SYSCOHADA for an OHADA subsidiary).
3. Step 3 - Setting up the day-to-day (weeks 3-5): configure your invoicing, templates, bank connection (Bridge), PPF / PA e-invoicing and, where relevant, payroll. From there, you enter and invoice in CassKai in real time.
4. Step 4 - Articulation with the firm (weeks 5-8): at closing, you send your chartered accountant the exports needed for review and the balance sheet (FEC, trial balance, journals), directly from CassKai. The firm keeps its advisory and assurance role; you keep control of the day-to-day.
