Does TechUltra have a team in France?

Senior consultants with French compliance expertise — VAT, PCG (plan comptable général), and the e-invoicing and e-reporting mandate. French-speaking team members for invoice template review and customer-facing communications where appropriate. Implementation lead, technical lead, project manager dedicated per engagement. French partner firm in Paris — same time zone, EU jurisdiction.

Do you have a French office?

Not an office of our own — TechUltra has one office, in Ahmedabad. France is covered through a B2B collaboration with a local partner firm in Paris, with India HQ engineering depth behind it. Same time zone, same jurisdiction. On-site work in France straightforward when needed. Most communication via video and async, with French-speaking team members on relevant calls.

What are the French e-invoicing dates?

Receiving: 1 September 2026 for all businesses in scope. Issuing: 1 September 2026 for large companies and mid-sized companies (ETIs), and 1 September 2027 for SMEs, very small businesses and micro-businesses, according to the DGFiP's start-up guide.

What do Odoo migration services include?

A read-only audit of your current ERP; field-by-field data mapping with quality issues flagged before cutover; idempotent Python migration scripts you can re-run against staging; a decision on each custom feature (port it or let Odoo's default replace it); integrations rebuilt against Odoo's API and re-tested in UAT; a 2–4 week parallel run with daily reconciliation; a rehearsed cutover with a documented rollback; and 90 days of hypercare. The price is fixed after a one-week discovery.

Do we need a migration or an Odoo upgrade?

If you are leaving another system (SAP Business One, NetSuite, Dynamics, Tally, Zoho, QuickBooks, Sage, a custom ERP), it is a migration and this page applies. If you are already on Odoo 15–19 and want Odoo 20 while keeping your build, it is a version upgrade: the database moves through each version in order and your custom modules are ported. See Odoo upgrade services, or size it yourself on odooupgrades.com, our dedicated upgrade site, which also handles Odoo 8–15. Both start with the same one-week discovery, so you do not have to decide before talking to us.

Odoo Gold Partner — Migration & upgrades

Odoo Migration in France

TechUltra Solutions delivers Odoo to French businesses through our French partner firm in Paris, with India HQ engineering depth behind it. We focus on the B2B e-invoicing mandate: since 1 September 2026 every business must be able to receive e-invoices and large companies and ETIs must issue them; SMEs and micro-businesses must issue from 1 September 2027. Invoices go through an accredited platform (plateforme agréée), which Odoo provides, in Factur-X or UBL, with e-reporting for sales to consumers and foreign customers.

What's included in Odoo migration for France

Safe, hassle-free Odoo upgrades and migrations from SAP, QuickBooks, Tally, NetSuite, Microsoft Dynamics, or older Odoo versions. Zero data loss, minimal downtime, and a four-stream playbook (Data Migration → Module Migration → System Migration → Version Upgrades) delivered by an Odoo Gold Partner.

Source-system audit

Read-only access to your current ERP. We document data structures, custom fields, integrations, custom code, and all the undocumented tribal knowledge.
Data mapping

Field-by-field mapping from your source system to Odoo. Edge cases, legacy values, and data-quality issues are flagged for cleanup before cutover.
Migration scripts

Idempotent migration scripts written in Python — re-runnable as many times as you need against staging before the production cutover.
Process redesign

Many 'must-have' source-system features turn out to be workarounds for old problems. We map current processes to Odoo's defaults and flag where defaults are better.
Custom feature port

Custom features in your source system get ported to Odoo only if they still solve a real problem. We don't recreate dead workflows just because they exist.
Integration rebuild

Connectors to your CRM, payment gateway, e-commerce, and vertical SaaS rebuilt against Odoo's API. We re-test each integration end-to-end during UAT.

How we migrate you to Odoo in France

Discovery + source audit — 1 week

One-week deep dive into your current ERP — data, integrations, custom code, undocumented behavior. Output: a written diagnostic and risk register.
Migration blueprint — 1–2 weeks

Field-level data mapping, custom-feature port list, integration rebuild plan, parallel-run plan, and cutover playbook. All signed off before build.
Build and migration scripting — 8–14 weeks

Iterative two-week sprints. Migration scripts run against staging from week one. Custom features and integrations rebuilt in parallel.
User acceptance testing — 2 weeks

Real-data UAT with the team running their actual workflows. Migration scripts re-run as many times as needed against staging until UAT passes.
Parallel-run period — 2–4 weeks

Both old and new systems run side-by-side for 2–4 weeks. Daily reconciliation reports highlight any discrepancies. Issues fixed in scripts and re-run.
Cutover and hypercare — 1 weekend + 90 days

Cutover weekend with rehearsed rollback. 90 days of post-launch hypercare from a dedicated team after the new system is live.

A typical mid-market migration runs 14–24 weeks end to end: 1 week discovery and audit, 1–2 weeks blueprint, 8–14 weeks build, 2 weeks UAT, 2–4 weeks parallel run, then cutover. The parallel-run period is non-negotiable — it's how we catch the data-quality issues that always surface only with real production transactions. Migrations from clean modern systems (NetSuite, Zoho) are faster than from legacy systems with 10+ years of accumulated edge cases (custom-built ERPs, old SAP installations). Multi-entity migrations are phased: lead market first, then expand.

France compliance we configure out of the box

Regulatory regimes that apply to odoo migration in France, and what each requires of the Odoo configuration.
Standard	What it requires
B2B e-invoicing mandate (2026–2027)	Receiving for all from 1 September 2026; issuing for large companies and ETIs from 1 September 2026 and for SMEs and micro-businesses from 1 September 2027. Factur-X (hybrid PDF + XML) and UBL generation, sent and received through Odoo's approved platform or another plateforme agréée.
E-reporting	Transaction data, and in some cases payment data, for sales to consumers and foreign customers, sent through the same platform. Same Odoo records, no re-keying.
TVA (VAT) returns and Intrastat	Monthly / quarterly TVA returns generated in the DGFiP-required format. Intrastat declarations for intra-Community trade. Permanent VAT registration tracking.
Plan comptable général (PCG)	French PCG chart of accounts pre-configured. Customisation per business sector (industrial, commercial, services) while preserving PCG structure.
FEC (Fichier des Écritures Comptables)	FEC accounting file generated in DGFiP-required format for tax audit. Includes all accounting entries with required metadata. Generated on demand or scheduled monthly.
Bilingual French + English invoicing	Invoice templates rendered bilingually with French primary. All DGFiP-required fields properly localised: SIREN, TVA intracommunautaire, mentions obligatoires.

Odoo Migration pricing in France

Every French project is priced to its scope. Cost depends on user count, entity count, modules, integrations and e-invoicing readiness. You get a fixed price after discovery, in EUR, before any build starts. Odoo Enterprise licensing is separate, billed by Odoo at its price list for your country (odoo.com/pricing). E-invoicing readiness on an existing Odoo database is quoted on its own, plus platform fees.

What moves the price

Source-system complexity

Migrating from a clean modern SaaS ERP is faster than from a 12-year-old custom system with no API and inconsistent data. We audit before quoting so you know what you're paying for.
Data depth and history

Migrating master data + 12 months of transactions is fast. Migrating 5+ years of history with full reconcilability adds 2–4 weeks. We'll honestly tell you when older history is better off in cold storage.
Custom feature port count

Each custom feature ported to Odoo carries an effort estimate. Our default is to port nothing and let the team try Odoo's defaults during UAT — most 'must-have' features turn out to be workarounds.
Integration rebuild count

Each connector to a third-party system needs to be re-pointed at Odoo and re-tested. The cost depends on how the integration was originally built, not just the count.
