Odoo Gold Partner — Migration & upgrades
Odoo Migration in Spain
TechUltra Solutions delivers Odoo to Spanish businesses from our Italian partner firm in Rome with India HQ engineering depth. Spain's e-invoicing trajectory — Verifactu (mandatory from 2026 for software vendors and businesses choosing the regime), TicketBAI (Basque Country since 2022), Crea y Crece Law driving B2B e-invoicing — makes 2026–2027 the readiness window. We handle IVA returns, modelo declarations (303, 390, etc.), PGC (Plan General de Contabilidad), and bilingual Spanish + English templates.

What's included in Odoo migration for Spain
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 Spain
-
Discovery + source audit — 2 weeks
Two-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: 2 weeks 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.
Spain compliance we configure out of the box
| Standard | What it requires |
|---|---|
| IVA (Spanish VAT) returns | Monthly / quarterly IVA returns via Modelo 303 generated in AEAT-required format. Annual Modelo 390 summary. Standard rate 21% plus reduced rate 10% and super-reduced rate 4% per supply category. Intra-Community supplies via Modelo 349. |
| Verifactu (national e-invoicing) | Verifactu-compliant invoicing for businesses choosing the regime — invoice metadata transmitted to AEAT, chain validation, fiscal anti-fraud compliance. Mandatory for new software developed for use in Spain from July 2025; broader business adoption rolling out. |
| TicketBAI (Basque Country e-invoicing) | TicketBAI compliance for businesses operating in the Basque Country (Álava, Gipuzkoa, Bizkaia) — required since 2022/2023 per province. Invoice signing, transmission to local hacienda, fiscal chain integrity. Distinct from Verifactu. |
| Crea y Crece Law (B2B e-invoicing) | Spain's Crea y Crece Law mandates B2B e-invoicing rolling out by enterprise size. Receiving capability ramping; issuing per business size cohort. EU EN 16931 / Peppol BIS compatible. |
| Plan General de Contabilidad (PGC) | PGC-compliant chart of accounts pre-configured. Customisation per business sector while preserving PGC structure for Spanish financial reporting (cuentas anuales). |
| SII (Suministro Inmediato de Información) | For businesses in scope (large enterprises, monthly VAT filers), SII real-time VAT reporting to AEAT. Native Odoo integration generates and transmits invoice data within the SII window. |
Odoo Migration pricing in Spain
Spanish Odoo implementation typically lands at EUR 22,000–60,000 (USD 24,000–65,000) fixed-price for single-entity 30–150 user deployments. Multi-entity Spanish groups: EUR 45,000–115,000 (USD 49,000–125,000). Add EUR 21,000/year (USD 22,800/year) for Odoo Enterprise Custom 50-user license. Verifactu readiness (existing Odoo): EUR 6,000–14,000 standalone. TicketBAI specific (Basque Country): EUR 8,000–18,000.
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.

How long does an Odoo migration take in Spain?
A typical mid-market migration runs 14–24 weeks end to end: 2 weeks 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. Spain-specific compliance configuration (IVA (Spanish VAT) returns, Verifactu (national e-invoicing)) is built into the setup phase rather than bolted on at the end.
-
Does TechUltra have a team in Spain?
Senior consultants with Spanish compliance expertise — IVA, PGC, Verifactu, TicketBAI, AEAT submission workflows. Spanish-speaking team members for finance work and customer-facing communications. Implementation lead, technical lead, project manager dedicated per engagement. Italy office (Rome) — same time zone, EU jurisdiction.
-
Do you have a Spanish office?
Not yet — Spanish engagements delivered from our Italian partner firm in Rome with India HQ engineering depth. Same time zone (CET), same EU jurisdiction, EU GDPR compliant. On-site work in Spain straightforward when needed. Most communication via video and async, with Spanish-speaking team members on relevant calls.
-
Verifactu — what is it and when does it apply to us?
Verifactu is Spain's national e-invoicing / fiscal anti-fraud regime. Software developed for billing use in Spain from July 2025 must be Verifactu-compliant; businesses can opt into the regime for fiscal anti-fraud assurance. Broader mandatory adoption is phasing in. Our Odoo build is Verifactu-compatible.
-
How long does an Odoo migration take?
Mid-market migrations typically run 14–24 weeks end to end, including a 2–4 week parallel-run period before cutover. Migrations from clean modern systems (NetSuite, Zoho) are faster; migrations from legacy custom-built ERPs with 10+ years of history take longer. Multi-entity migrations are phased — lead market first, then expand to other countries.
-
Will we lose data during the migration?
No data-loss events since 2016 across 100+ migrations. Migrations run via idempotent scripts against a staging environment first, with daily reconciliation reports during the parallel-run period to catch any discrepancies before cutover. The rollback plan is documented and rehearsed; we've used it twice and both rollbacks were successful.
