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

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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

Regulatory regimes that apply to odoo migration in Spain, and what each requires of the Odoo configuration.
StandardWhat it requires
IVA (Spanish VAT) returnsMonthly / 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.

Odoo Migration in Spain: frequently asked questions

  • 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.
