Maarten Gerits
Odoo Finance Expert | Business analysis and integration | CFO experience
I translate financial processes into Odoo: from tariffs and subscriptions to invoicing rules and posting logic, through to reconciliation and month-end close.
Since 2019 I have done this as Lead Business Consultant at Dynapps, the largest Odoo partner worldwide. There I am the most experienced finance expert: colleagues and clients bring me their complex finance questions.
Before that I was a CFO for more than nine years. So I speak the language of Finance as well as that of the developers.
- 7years of Odoo Finance, since version 13
- 100+companies guided through Odoo projects
- 15+years of ERP experience, as client and as implementer
- 9+years as CFO and member of the management team
About me
As Lead Business Consultant at an Odoo partner, I lead finance projects from FIT/GAP analysis to delivery, in Belgium and for entities in the Netherlands, Germany, Spain, France, the US and the UK. I write the analyses and functional specifications myself, so developers can get to work without further interpretation.
My strength is the finance impact across all apps: invoicing, subscriptions, inventory, point of sale, projects and expenses, and the integrations with external systems. I also coach senior, medior and junior consultants.
I use it myself as well: for my own ticketing platform I work with Mollie and reconcile the payouts, and part of my own clients are on a subscription plan.
Before that I was on the client side myself. As Group CFO of a family-owned retail group (12 to 18 companies in Belgium and the Netherlands) and as CFO of a textile producer, I owned ERP projects and turned around a stalled implementation. Ten years of audit and accountancy gave me the foundation: VAT, closing, reconciliation and audit trail.
My principle: users must always be able to see how the system arrives at a result. Every invoice line must be traceable back to its source and forward to its journal entry.
I have been a self-employed entrepreneur for more than 25 years.
What I bring
One profile that designs and documents the financial flows and makes them reconcile all the way to the general ledger.
