Odoo vs Holded (2026): which ERP really suits your SME?

1. Philosophy and architecture

To understand how each behaves day to day, start with how they are built and what they were designed for.

Holded: the all-in-one tool for agile management

Holded was founded in Barcelona in 2016 by Javier Fondevila and Bernat Ripoll and acquired in 2021 by the Norwegian group Visma. The company cites more than 900,000 users. It is software as a service (SaaS) focused on day-to-day admin: invoicing, accounting, cash management, a light CRM, projects and basic inventory, with a modern interface. It avoids consulting projects: a freelancer or micro-business can sign up, connect its banks and import its catalogue in hours or a few days.

Odoo: the open, modular ERP suite

Odoo was born in Belgium in 2005 and is one of the most widely used open-source ERPs in the world. It runs on a single data model shared by dozens of official apps and a large store of community and third-party modules. Every sale, stock move or HR record is reflected automatically in accounting and the rest of the processes, with no external connectors.

It comes in two editions —Community, free under the LGPL-3.0 licence, and paid Enterprise— and three deployment options:

• Odoo Online: its cloud, managed by the vendor. The simplest option, but it does not accept custom-built modules.
• Odoo.sh: platform as a service (PaaS) for projects with customisations, integrated with GitHub.
• Your own server or private cloud: installed on your infrastructure or providers such as AWS or Hetzner.

2. Features and tax compliance in Spain

How well software fits depends on how deep it goes in each area of the business. Here is the summary by module:

Finance and compliance

Holded stands out for its fit with Spanish taxation: it drafts the VAT (303, 390) and income tax withholding (111, 190) returns and form 130, includes bank reconciliation and issues VeriFactu-ready invoices. If your accountant is a Holded Partner, they get free access without taking a user seat. Its accounting engine, however, is subordinate to invoicing, which makes complex analytic accounting or multi-company consolidation harder.

Odoo, through its Spanish localisation, covers the Spanish chart of accounts, tax returns, statutory books, fixed assets and the requirements of VeriFactu, TicketBAI and SII (immediate VAT reporting). Its big difference is multi-dimensional analytic accounting: every income or expense can be allocated in real time to projects, cost centres, departments or business lines.

Warehouse and inventory

Holded offers stock control designed for shops or service companies selling finished products. Multi-warehouse and advanced traceability need the inventory add-on (+€25/month). Odoo works with double-entry inventory, internal locations, lot or serial traceability, automatic replenishment rules (min/max or make-to-order), real-time stock valuation and multi-step picking and packing.

Manufacturing

Holded's manufacturing add-on (+€25/month) is limited to assemblies and kits: it does not plan capacity, manage shop-floor work orders or production routes. Odoo includes full manufacturing with multi-level bills of materials, production orders, routings per work centre, time tracking per operator, quality, maintenance and product lifecycle management.

3. Real prices in 2026: plans, modules and add-ons

The pricing models are very different: Holded charges a plan per company and adds add-ons; Odoo charges per user and gives access to every app.

Holded: plans and add-ons

As the company needs more, the fee grows with add-ons:

• Extra user: +€10/month per user.
• Advanced inventory: +€25/month.
• Point of sale (POS): +€25/month per shop.
• Manufacturing: +€25/month.
• SII connection: from +€30/month.
• Payroll: €5/employee per month (team management from €1.50/employee).
• B2B catalogue: +€10/month. Premium support: +€50/month.

Odoo Enterprise: price per user, every app

4. The hidden costs of implementing an ERP

In Odoo, licences are only part of the first-year budget. Rolling out a modular ERP requires a consulting, configuration and data migration project.

Typical Odoo implementation ranges in Spain

5 indirect costs to plan for

1. 01Migrating accounting history. Importing customers and products is simple; migrating several years of reconciled entries and taxes can add several thousand euros. We break it down in how much an Odoo implementation costs.
2. 02Keeping the tax localisation up to date. Regulations change often and the localisation has to keep up.
3. 03Version upgrades. Odoo releases a major version every year. Upgrading the standard is covered in Enterprise, but custom developments must be reviewed and migrated.
4. 04Training and support. Real adoption needs support for the team during the first weeks in production.
5. 05Hosting. With the Custom plan on Odoo.sh or your own server, budget for the infrastructure.

5. 3-year total cost for three types of SME

To see the real financial impact, this table projects the cumulative 3-year cost for three company profiles in Spain.

The crossover point: modules, not headcount

When Odoo starts to cost less per month does not depend on headcount but on how many operational modules you need:

6. Ease of use and user reviews

Holded scores very well on ease of use: people with no accounting background can issue invoices on day one. Criticism focuses on slow chat support at peak times and the cost of adding add-ons.

Odoo has a modern interface but a lot of functional density: configuring the accounting localisation, taxes, warehouses or approval flows needs design upfront. Many of its negative reviews come from companies that tried to implement it without professional help or whose consulting budgets fell short.

8. Decision guide: which ERP should you choose?

The question is not which software is better, but which one matches your company's complexity.

Choose Holded if…

• You are a team of 1 to 10 people in services: agencies, consultancies, professional firms, developers or renovation companies.
• Your priority is admin: quotes, invoices, digitised expenses and bank reconciliation.
• An accounting firm keeps your books: you want them to access your data without emailing files.
• You do not manufacture or run complex logistics: you sell services or finished products without strict traceability.
• You want to start now at minimal cost: with no implementation project.

Choose Odoo if…

• You are an industrial or processing SME: you need material planning, shop-floor control and production routings.
• You distribute or run several warehouses: you need lot or serial traceability, zone picking and automatic replenishment.
• You sell through several channels: you want e-commerce, physical shops, sales team and warehouse in one database.
• You have several companies or need analytics: multi-dimensional analytic accounting, consolidation or multi-company management.
• You think 5-10 years ahead: you would rather invest in an implementation now than migrate systems later.
