Holded and Odoo show up together in a lot of searches because they compete, partly, for the same customer: the Spanish SME that wants to leave Excel and loose PDF invoices behind. But they only really compete in one specific slice -invoicing, basic accounting and a simple CRM-. Outside that slice, they are tools from different categories: Holded is cloud management software focused on invoicing and accounting for small businesses; Odoo is a modular ERP, with more than 80 official apps and thousands of third-party modules, built for operations that grow in complexity: multiple warehouses, manufacturing, marketplace sales, compliance across several countries.
Key point: if your business runs from a single site, invoices a few dozen lines a month and doesn't manufacture or sell on marketplaces, Holded is probably more than enough and saves you money. As soon as a second warehouse, a bill of materials, an extra sales channel or the need to truly customize a process shows up, Odoo starts to pay off.
What Holded is and who it's built for
Holded is Spanish-born cloud management software focused on invoicing, accounting, projects and a simple CRM. Its strength is speed: you sign up, connect your bank account, issue your first invoice and have your accounting reconciling itself in a short while, without installing anything or depending on an IT department. It's a closed subscription -no access to the code, no self-hosting option- built so a freelancer or a small business has everything solved with minimum friction.
That same design -everything integrated, everything simple- is what makes it fall short when the business grows in another direction: stock management across several warehouses with replenishment routes, manufacturing with bills of materials, native integrations with marketplaces like Amazon or Shopify, or the need to adapt a specific process to how your company actually works instead of the other way around.
What Odoo is and why it plays in a different league
Odoo is an open-core modular ERP: a free Community core you can install anywhere, plus a paid Enterprise edition with additional apps, advanced reporting and official support, and the option to host it on Odoo Online or Odoo.sh or on your own server. Its catalog of official apps -sales, purchasing, inventory, manufacturing, HR, projects, point of sale, maintenance, quality, field service, and many more- can be installed on demand depending on what each business needs, something a closed SaaS like Holded doesn't offer by design.
When Holded is the right choice
- You're a freelancer or SME with a single point of sale or warehouse
- You invoice a few dozen documents a month
- You don't manufacture or assemble product
- You don't sell on marketplaces or run complex logistics
- You prioritize low cost and going live in days, not weeks
- Your accountant already works well with what it exports
For that profile, Odoo is overkill: you'd be paying for operational capacity you won't use, and the implementation -reasonable as it is- weighs more than what Holded solves in an afternoon.
When Odoo starts to pay off
Multi-warehouse stock and routes
As soon as you work with more than one warehouse -or with locations inside the same warehouse (receiving, quality, shipping)- you need configurable stock routes and automatic replenishment between them. Holded manages inventory at the level of listings and quantities, but has no routing engine or native lot/serial traceability; Odoo does.
Manufacturing
If your company manufactures or assembles what it sells -bills of materials, manufacturing orders, quality control-, Holded has no module for that. It's exclusive territory for an ERP like Odoo.
Marketplaces and ecommerce
Selling on Amazon, Shopify, Leroy Merlin, Decathlon or any other marketplace with stock and orders synced in real time requires dedicated connectors per channel. Odoo has a connector ecosystem for that -including FlexigoTech's 86 proprietary modules-; Holded isn't built as a multichannel management hub.
International compliance
If you invoice across several EU countries, each with its own e-invoicing format and its own VAT rules (OSS, VAT registration in several countries), you need a system that can adapt its tax engine country by country. Odoo, being modular, lets you add that layer per country without rebuilding the whole system.
Real customization
Holded offers configuration within the limits the SaaS itself allows. Odoo, with an open-source core, allows real custom development: a developer can modify any flow, not just switch it on or off from a settings panel.
Comparison table: Odoo vs Holded by area

Migrating from Holded to Odoo: what to keep in mind
Migrating isn't just exporting an Excel file of customers and invoices. You need to map the chart of accounts, decide which history gets imported (invoices, journal entries, balances) and in what format, configure taxes and invoice series according to your tax regime, and train the team on the new workflow. A well-planned implementation avoids the most common mistake: migrating the data but not the processes, and ending up using a whole ERP as if it were the old invoicing tool.
Our Odoo 19 implementation service covers exactly that: data migration, tax setup for Spain, and rollout of the modules your operation actually needs, without overloading the system with apps you won't use. And if you want to see the full scope before deciding, you can explore FlexigoTech's 86 proprietary modules for Odoo 19, from marketplaces to international compliance.
Frequently asked questions
Is Holded cheaper than Odoo?
For a small operation, yes: Holded has a fixed, predictable monthly fee, while Odoo adds a per-user license plus an initial implementation. The comparison changes as your operation grows: in Holded, whatever the SaaS doesn't cover you have to solve with additional tools (with their own cost), while Odoo centralizes that capacity within the same system.
Can I migrate my invoices and accounting from Holded to Odoo?
Yes. You can export the history of customers, invoices and journal entries from Holded and import it into Odoo, mapping the chart of accounts and respecting the numbering of the invoice series already issued. It's a migration job worth planning in detail, not a simple copy-paste.
Does Holded work for selling on marketplaces like Amazon?
Holded isn't built as a multichannel management hub with dedicated marketplace connectors; its strength is invoicing and accounting. To sync stock, orders and prices with Amazon, Shopify or other channels in real time, an ERP with specific connectors like Odoo is usually the more robust option.
Do I need to be a developer to customize Odoo?
Not necessarily. Odoo Studio lets you customize fields, views and automations without coding. For deeper changes to business logic you do need custom development, something Holded's closed model doesn't allow at all because it gives no access to the code.
When does it make sense to switch from Holded to Odoo?
When any of these symptoms shows up repeatedly: you manage stock in more than one warehouse, you start manufacturing or assembling product, you sell on more than one channel with shared stock, you invoice in more than one country, or you need the system to adapt to a specific process in your company instead of adapting your process to the system.
