Holded and Odoo appear side by side in almost every ERP comparison for Spanish SMEs. Both are cloud-based solutions, both integrate accounting, invoicing and CRM, and both have accessible entry-level versions. But that is where the similarities end. Beneath the surface, they follow very different philosophies: Holded is a product designed so that a small company can start organising its processes with minimal friction; Odoo is a platform built to grow without having to change systems. Making the wrong choice at this point carries a real cost: migrating an ERP at the wrong time — upwards or downwards — consumes between three and six months of internal work and implementation fees ranging from €8,000 to over €40,000 depending on complexity (market ranges documented by ERP implementation consultancies in Spain, 2024-2025). This article gives you the objective criteria to make the right decision.
Holded: what it is, what it does well and where it falls short
Holded was founded in Barcelona in 2016 and acquired by Visma in 2021. It is a modern SaaS ERP with a clean interface and a low learning curve. Its strength is the native integration between accounting, invoicing, inventory, projects and CRM in a single monthly subscription with no upfront implementation cost if the company handles configuration itself.
Holded's pricing model in 2025 is based on plans by number of users and active modules, with a very competitive entry level for companies of 1 to 10 people. Spanish accounting (General Accounting Plan, SII, Verifactu) is included as standard, which eliminates complex integrations for freelancers and micro-enterprises.
Holded starts to show its limits once the company exceeds a certain data volume or requires specific vertical processes. Customisation is limited: there is no third-party module ecosystem comparable to Odoo's, and the API extension options, while they exist, do not allow complex business logic to be built without leaving the platform. Performance with catalogues of more than 10,000 references or invoicing histories spanning more than four or five years begins to feel the strain. There is also no on-premise or self-hosted version: if the company has strict data sovereignty policies, Holded is not an option.
Odoo: what it is, what it does well and where it falls short
Odoo is an open-source ERP of Belgian origin (founded in 2005 as TinyERP) that today counts more than 12 million users in over 100 countries, according to figures published by Odoo S.A. The Community version is free; the Enterprise version adds proprietary modules (advanced accounting, electronic signature, e-commerce with marketing automation, etc.) and official support, at a per-user, per-month price that varies by partner and number of active modules.
Odoo's key differentiator is its ecosystem: more than 40,000 modules on Odoo Apps (official marketplace figure as of January 2026), several hundred of which are certified by Odoo S.A. There are vertical modules for hospitality, construction, manufacturing, distribution, clinics and virtually every sector. The modular architecture allows you to activate only what you need and deactivate what you do not, which controls licence costs.
The trade-off is complexity: Odoo without a qualified partner is a tool that can turn into an endless project. Implementation requires process analysis, data migration, configuration and training. That has a cost in time and money that Holded does not demand at the outset. Major version upgrades (Odoo 16 → 17 → 18) also involve technical work that must be planned for.
Direct comparison: Holded vs Odoo on the criteria that matter
| Criterion | Holded | Odoo Community | Odoo Enterprise |
|---|---|---|---|
| Licence model | SaaS (monthly subscription) | Open-source, free | SaaS / on-premise (per-user pricing) |

Signs that it is time to migrate from Holded to Odoo
There is no universal size rule that marks the tipping point. It depends on the sector, the processes and the growth ambition. In practice, these are the signals we see repeatedly in companies that come to us asking for a migration:
- Reports take too long or require exporting to Excel. When the team works with Excel files because the ERP cannot filter or consolidate as needed, the system has become too small.
- Processes live outside the ERP. Spreadsheets for production planning, external tools for project tracking, Google Sheets for warehouse control. Every informal integration is a source of errors.
- The inventory module cannot handle the catalogue. Holded manages basic inventories well; when variable attributes, batches, serial numbers, multiple warehouses or make-to-order production appear, the tool hits its limits.
- The company has more than 20-30 active users and Holded's cost approaches or exceeds that of Odoo Enterprise. Beyond that volume, the economic comparison starts to favour Odoo, especially when advanced modules are added.
- A manufacturing or MRP process is required. Holded has no manufacturing module; Odoo has one of the most complete in its price segment.
- The company operates in multiple countries or currencies. Odoo Enterprise's multi-company and multi-currency features are far more developed than Holded's.
When it makes sense to stay on Holded (or return to it)
Holded is the right choice for service companies of up to 15-20 people whose core business is invoicing and project management. If the flow is: proposal → order → invoice → payment, with some basic inventory, Holded resolves it with less friction and lower total cost than Odoo. It is also the logical choice for early-stage start-ups that need financial control but cannot afford the cost of a full implementation.
The most frequent mistake we see is the opposite: companies that implement Odoo Enterprise from day one without needing it, take on a disproportionate project cost for their volume and then use 15% of the features. Odoo is a powerful tool; using a highly complex system for a simple business means spending energy on the tool rather than on the business.
The migration process from Holded to Odoo: what to expect
A well-planned migration has four phases that Summum Sistemas has executed on numerous occasions with clients in Castilla y León and the Canary Islands. If you are considering making the move, our ERP Holded service page explains in detail how we support this process from start to finish.
- Data and process audit (2-3 weeks). Inventory of master data: customers, suppliers, items, price lists, accounting history, pending documents. Mapping of current processes to equivalent Odoo modules. Identification of required customisations.
- Configuration and data migration (4-8 weeks). Module installation and setup. Import of master data via CSV/API. Accounting reconciliation tests. Team training in a test environment.
- Parallel run (2-4 weeks). Both systems active simultaneously. Validation that period closes match, that approval workflows function and that team members gain confidence in the new system.
- Cutover and stabilisation (2-4 weeks post go-live). Holded deactivated on the agreed date. Intensive support during the first weeks. Fine-tuning of reports and automations.
The realistic total timeline is three to five months for a company of 15-50 people, with an internal load of two to four hours per week for the project owner on the client side. There is no such thing as a two-week magic migration: anyone selling you that has never migrated anything of real complexity.
Integration with the digital ecosystem: ERP is not an island
Both Holded and Odoo offer documented REST APIs, but the depth is very different. Holded has native integrations with Stripe, Shopify, WooCommerce and some accounting tools, but the catalogue is closed. Odoo allows practically any external system to be integrated through marketplace connectors or custom development.
If your company already has an online store, a support ticket system, an external project management tool or a specialist CRM, the choice of ERP must account for integration costs. In some cases, Odoo eliminates the need for external tools (it has its own CRM, helpdesk, e-commerce and project management); in others, Holded plus three connectors can be cheaper and sufficient.
For companies that need to automate flows between systems — for example, syncing Shopify orders with the Odoo warehouse or automatically generating delivery notes from an external sales channel — the process automation layer plays a critical role. Our ERP implementation and migration service covers both ERP configuration and integration with the rest of the client's digital stack.
Use cases by sector: who chooses what and why
There is no universal answer; it depends on the sector and the growth stage. These are real patterns we observe in the Spanish SME market:
- Professional services firms and consultancies (5-20 people): Holded covers project management, invoicing and accounting well. They migrate to Odoo when they consolidate multiple companies or need a more complete HR module.
- Distributors and wholesalers (10-80 people): Odoo is the natural choice from the outset if the catalogue exceeds 2,000 references or if there are multiple warehouses. The purchasing module and basic MRP justify the investment.
- Make-to-order manufacturers: Odoo MRP with no reasonable alternative in this price range. Holded has no manufacturing module.
- Pure e-commerce (B2C online store, 1-5 people): Holded or even specialist tools (Shopify + Xero) can be more efficient than Odoo, whose strength in e-commerce is B2B integration or omnichannel.
- Agri-food sector and wineries: Odoo with batch traceability and expiry date control modules. Holded does not cover batch traceability with sufficient granularity.
- Hospitality and restaurant chains: Odoo with the Hospitality module or integrated POS; Holded is insufficient for managing multiple points of sale with shared stock.
Frequently asked questions
Can I migrate the accounting history from Holded to Odoo?
Yes, but with nuances. Journal entries for the current year and opening balances are migrated via CSV file import or through the Holded API. Historical data from closed financial years is usually imported as consolidated opening entries, not entry by entry. The level of detail migrated depends on how much history you need operational in the new system: the norm is to keep the last two financial years in detail and the earlier ones in a reference system (an Excel file or a PDF exported from Holded).
Does Holded export data before cancelling the subscription?
Yes. Holded allows you to export customers, suppliers, products, invoices and accounting entries in CSV format directly from the administration panel. It is advisable to do this complete export before starting any migration process and to keep a copy outside the platform. Once you cancel the subscription, access to data is subject to a limited period according to their terms of service.
How much does it cost to implement Odoo in a 20-person SME?
The cost depends on which modules are activated, the volume of data to migrate and the complexity of the processes. As a market reference (not a Summum price), Odoo Enterprise implementation projects for SMEs of 15-30 people in Spain typically range from €10,000 to €30,000 in consultancy and implementation fees, plus the annual Odoo S.A. licence costs (which vary by number of users and modules). Projects involving manufacturing, e-commerce integration or multiple companies can exceed that range.
Is Odoo Community or Odoo Enterprise better for an SME?
Odoo Community is free and covers most operational functions, but it lacks proprietary modules that are key for the Spanish market: the advanced accounting localisation (including the certified Verifactu module), electronic signature, the full HR module and official support. For a Spanish SME that needs to comply with Verifactu (mandatory for companies from 1 January 2027 and for self-employed workers from 1 July 2027, under Royal Decree 1007/2023 and subsequent deadline updates), Odoo Enterprise with the Spanish localisation is the safest path. Odoo Community may be sufficient for companies with basic accounting needs and an internal technical team.
