Thibault Mersac

Owner @Atelier Mersac

"Our projects used to take 2 to 3 months to get paid — it was killing our cash flow. Our Sanso manager knows every job file inside out, follows up at exactly the right time, and flags alerts as they come up. In 4 months, we recovered €85,000 in cash."

"We're a team of 12 and I don't have a CFO. Arielle has become my back-office manager: she handles my invoices, my follow-ups, my bookkeeping prep — and most importantly, I stay in control of every decision that matters."

SERVICES

SERVICES

A modular offering. Tailored to you

Your finance back-office covers all the day-to-day operations that keep your business running — but shouldn't be taking up your leadership team's time. Your dedicated Sanso account manager takes on the operational load, backed by our internal technology that automates everything that can be automated. You keep the strategy and the decision-making.

Invoicing & Collections

We issue your invoices, track payments, and follow up with your clients — by email, by phone, at the right moment. Your DSO drops, your clients pay, and you stop chasing people down.

Bookkeeping Prep

Bank reconciliation, account matching, organized receipts, journal entries ready to go. Your accountant receives a clean file, and your month-end closes in days instead of weeks.

Vendor Management

Collection, verification, reconciliation, payment. No more pile of overdue PDFs, forgotten disputes, or avoidable late fees.

Reporting & Dashboards

Cash flow dashboard, margins, DSO, runway. Up-to-date figures, with monthly commentary from your dedicated manager. You run your business on real data — not a spreadsheet from three weeks ago.

FAQ

How does the human + tech duo actually work?

A dedicated manager — a senior SMB finance expert — handles your account end-to-end and remains your single point of contact. They're backed by our AI technology, which connects to your tools and automates 60–80% of repetitive tasks (invoice reading, reconciliation, follow-ups, reporting). The result: your manager spends their time on analysis, judgment calls, and your relationship — not on data entry.

What if my manager is away or unavailable?

Two guarantees. First, a designated backup manager within Sanso steps in immediately in case of leave, illness, or peak activity. Second, everything about your account — invoices, follow-ups, anomalies, decisions — is centralized in our technology, not locked in one person's head. The backup gets up to speed in minutes, not days. Your follow-ups go out, your invoices get issued, your reconciliations get done.

Does Sanso replace my accountant?

No — and that's by design. Sanso works alongside your accountant, not instead of them. Your manager prepares and organizes the data (invoices, reconciliations, receipts, account matching) so your firm can work with it directly. In practice, our clients tell us their accountants love it: they finally receive a clean, up-to-date file, and closings happen faster.

Will I need to change my tools or processes?

No. Nothing to install, nothing to migrate, nothing to relearn. Sanso adapts to your current environment — Pennylane, Sage, Cegid, Quadratus, EBP, your bank, your CRM — and to your existing workflows. Your manager learns how you work, not the other way around. That's actually one of the main reasons our clients leave their previous provider.

How much does it cost, and can I leave if it doesn't work for me?

Starting at €500/month, adjusted based on your scope (invoicing, collections, vendors, bookkeeping prep, reporting) and your volume. A clear quote in 15 minutes over the phone, no surprises. Yes, you can leave at any time — no notice period, no exit fees. We'd rather have a happy client who stays five years than a locked-in client who resents us.
