Business Analyst Odoo Finance Billing

Keystone Solutions is seeking a Business Analyst specializing in Finance & Billing for a consultancy mission at a client site. In this role, you will be instrumental in integrating a new charging platform with existing ERP and billing systems, ensuring robust financial flows and accurate billing processes.

• →Take functional ownership of the financial scope of the Odoo implementation.
• →Map end-to-end financial flows: B2B, B2C, fleet, split billing, CPO revenue, and eMSP roaming, from session to invoice, payment, and journal entry.
• →Translate tariffs, subscriptions, bundles, promotions, and roaming agreements into Odoo billing rules and accounting logic.
• →Produce current-state and future-state process documentation, functional specifications, data mappings, interface contracts, and business rules for the CPMS ↔ Odoo ↔ PSP ↔ bank integration.
• →Define accounting treatment with Finance: accounts, VAT, analytics, accruals, credit notes, and revenue recognition.
• →Design reconciliation between CPMS transactions, PSP settlements, bank statements, and the general ledger, including exceptions and disputes.
• →Run workshops, challenge requirements, arbitrate standard vs. custom Odoo behavior, and keep scope under control.
• →Own the finance backlog: user stories, acceptance criteria, prioritization, and delivery follow-up.
• →Build and run finance testing: integration tests, UAT, simulated month-end close, and reconciliation dry-runs.
• →Ensure full auditability: every invoice line can be traced back to a charging session and forward to the corresponding accounting entry.

• You hold a bachelor’s or master’s degree in finance, accounting, economics, business engineering, or an equivalent field, or have acquired equivalent expertise through professional experience.
• You bring at least 4-5 years of experience as a business analyst or functional analyst in finance, billing, or ERP environments, and you are comfortable representing Finance in technical discussions.
• You are fluent in English (mandatory) and have a good command of French or Dutch.
• You master the fundamentals: AR/AP, invoicing and credit notes, VAT, accruals, reconciliation, month-end close, and audit trail.
• You are an Odoo expert with hands-on experience in Accounting, Invoicing, and Subscriptions, able to translate business needs into workable Odoo configurations and specifications.
• You are at ease with high-volume, automated transaction flows and design controls around exceptions rather than checking every item manually.
• You communicate clearly in writing, producing specifications, mappings, and test cases that developers can use without further interpretation.
• You challenge unclear ownership, dig into discrepancies until you find the root cause, and keep Finance, Commercial, Product, and IT aligned.
• Experience in e-mobility, energy, payments, telco, or another usage-based billing environment is a strong advantage.

You will design the financial backbone of a critical platform while the operating model is still being shaped, rather than inheriting an established model. The assignment has a broad scope: every business segment—B2B, B2C, fleet, public network, and roaming—depends on the flows you define. You will work in a cross-functional role at the intersection of finance, mobility, energy, and technology, supported by a strong internal team and experienced implementation partners. The result is visible and measurable: accurate invoices, reliable accounts, controlled cash flows, and an efficient month-end close.

• Type of engagement: freelance / consultancy assignment (self-employed or through a consultancy company).
• Workload: 5 days per week.
• Location: On-site presence expected during workshops, testing, and cutover phases.
• Daily rate: to be proposed, based on experience and seniority.
• Selection process: CV screening, intake interview, and a business case or technical deep-dive.
