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 deadlines are now fixed: Verifactu billing-software rules apply from 1 January 2027 for companies and 1 July 2027 for the self-employed, and Royal Decree 238/2026 makes B2B e-invoicing mandatory from about October 2027 for businesses with turnover above €8 million and a year later for the rest. TicketBAI has applied in the Basque Country since 2022. 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 — 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.
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 (billing software rules) | Billing systems must keep chained, tamper-evident invoice records and, in VERI*FACTU mode, send each record to the tax agency (AEAT). Applies from 1 January 2027 to companies paying corporate tax and from 1 July 2027 to the self-employed and other taxpayers (Royal Decree-law 15/2025). Businesses already on SII are exempt. |
| 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. |
| B2B e-invoicing (Crea y Crece, Royal Decree 238/2026) | Royal Decree 238/2026 makes B2B e-invoicing mandatory 12 months after its technical ministerial order for businesses with turnover above €8 million (expected October 2027) and 24 months after for all others (expected October 2028). Structured formats such as UBL and Facturae, with invoice status reported. |
| 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
Every Spanish project is priced to its scope. Cost depends on user count, entity count, modules, integrations and compliance work: Verifactu, B2B e-invoicing and, in the Basque Country, TicketBAI. 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). Verifactu, e-invoicing or TicketBAI readiness on an existing Odoo database gets a separate fixed quote.
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 much does an Odoo migration cost in Spain?
Every Spanish project is priced to its scope. Cost depends on user count, entity count, modules, integrations and compliance work: Verifactu, B2B e-invoicing and, in the Basque Country, TicketBAI. 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). Verifactu, e-invoicing or TicketBAI readiness on an existing Odoo database gets a separate fixed quote. Every TechUltra engagement is fixed-price after a one-week discovery, so the number you sign is the number you pay for the agreed scope.
-
How long does an Odoo migration take in Spain?
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. Spain-specific compliance configuration (IVA (Spanish VAT) returns, Verifactu (billing software rules)) 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. TechUltra's Ahmedabad HQ, working with our Italian partner firm in Rome.
-
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 anti-fraud standard for billing software: invoice records must be chained and tamper-evident and, in VERI*FACTU mode, sent to AEAT as each invoice is issued. Software vendors had to comply by July 2025. Users must comply from 1 January 2027 if they pay corporate tax, and from 1 July 2027 otherwise (Royal Decree-law 15/2025). Businesses on SII are exempt. Odoo's Spanish localization supports Verifactu.
-
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.
