Odoo, ERPNext and SAP Business One differ in licensing, how they are sold and who implements them. Compare them fairly on cost model, hosting, Saudi tax support, scale and skills, with no winner declared.
Odoo, ERPNext and SAP Business One are three different answers to the same problem, and they differ most in how they are licensed, how they are sold and who implements them. Odoo splits into a free Community edition and a paid Enterprise edition. ERPNext is open source. SAP Business One is proprietary software that SAP positions for small and midsize businesses. None is best for every company, so this guide compares them on documented facts and ends with a way to decide. DevMarket sells Odoo modules, among other things, so we have an interest in Odoo, and we have kept to what the vendors publish.
In short
Start with how each is built and sold. Prices and plans change, so use this as a map and confirm each row with the vendor.
| Odoo | ERPNext | SAP Business One | |
|---|---|---|---|
| Licence | Community: LGPL v3. Enterprise: proprietary licence, shared source | GPL-3.0 | Proprietary |
| Software cost model | Community free. Enterprise per user per month | Software free. Frappe Cloud priced by use, not per user | Licences and services typically quoted by SAP partners, on a named-user model |
| Hosting | Odoo Online, Odoo.sh or your own server | Frappe Cloud or your own server | Your own servers or the cloud |
| Database | PostgreSQL | MariaDB, per the project's README | Microsoft SQL Server or SAP HANA |
| Implementation | Odoo partners and Odoo's own packages | Frappe's certified partners | SAP partners |
Odoo is open core. Community is free software under the LGPL v3, and Enterprise is built on it under the Odoo Enterprise Edition License, which needs a subscription for the right number of users. The details are in Odoo Community vs Enterprise.
ERPNext is published under the GPL-3.0 on GitHub, and its website says no features are hidden behind paywalls. SAP Business One is commercial software used under licence terms agreed through a partner. SAP's licence guide for version 10.0 describes a named-user model, and current types and prices are best confirmed with SAP or a partner.
Both are web-based, written mainly in Python, and open source at their core. Odoo ships a wide catalogue of apps, including a website builder, eCommerce, marketing, events, eLearning and helpdesk, although several are Enterprise-only. ERPNext lists accounting, procurement, sales, CRM, stock, manufacturing, projects, assets, point of sale, quality and support, with HR and payroll in a separate Frappe HR product.
Customisation works differently. In Odoo, developers write modules in Python and XML, and Studio, an Enterprise tool, lets non-developers add fields, views and automation. ERPNext sits on the Frappe framework, where data models called DocTypes can be created from the interface and extended with custom apps in Python and JavaScript. Odoo has a large add-on market, with the Odoo Apps Store and sites such as DevMarket. A broader catalogue is not automatically better: judge each product on the processes you will actually run.
SAP positions Business One for small and midsize businesses. Its learning site says it can be hosted on your own servers or in the cloud, works with SAP HANA or Microsoft SQL Server, and is supported by more than 850 local partners, with 28 languages and 50 country-specific versions. The SAP page does not name those versions, so check yours.
Odoo's pricing page sends companies to different implementation routes by size: Success Packs below 50 employees, partners from 50, and Odoo itself from 250. ERPNext's pages do not state a size target, so ask its partners for references of your size.
The cost models differ too. Odoo publishes per-user plans, which makes a first estimate easy, as how much Odoo costs shows. For Business One you ask a partner for a quote that bundles licences, implementation and support. Neither is better in itself, but it means you should compare written quotes for the same scope rather than list prices. A company whose parent group already runs SAP may value the shared vendor and governance, while others may prefer Odoo's lighter start and choice of hosting.
Saudi requirements change, so treat every row as something to confirm. The ZATCA e-invoicing page is the authority, and our guides on ZATCA phase 2 for online stores and VAT and invoices in Saudi Arabia give background.
| Odoo | ERPNext | SAP Business One | |
|---|---|---|---|
| Arabic and right-to-left | Odoo can run in Arabic. Self-hosting needs rtlcss | Test the screens and print formats you need | SAP lists 28 languages. Confirm Arabic with SAP or a partner |
| Saudi VAT | A documented localisation with a chart of accounts, 15% VAT, zero-rated and exempt taxes, and a VAT return | A KSA VAT report and settings in the ERPNext docs | Check with the vendor or a partner |
| ZATCA e-invoicing | A phase 2 integration module with sandbox, simulation and production modes, per the documentation | A free open-source app, KSA Compliance, is listed on the Frappe Cloud marketplace for ERPNext versions 15 and 16 | Check with SAP or a partner |
A module existing is not the same as your company being compliant in its wave. Ask each vendor or partner for a live Saudi customer you can talk to.
| Company type | Worth shortlisting | Why |
|---|---|---|
| Small team with technical skills and a tight budget | ERPNext, or Odoo Community on your own server | No software licence fee, and you control hosting |
| Growing company that wants sales, stock, accounting and a website in one system | Odoo | A wide app catalogue and a choice of hosting |
| Group that already runs SAP at headquarters | SAP Business One | Shared vendor and governance, with a local SAP partner |
| Gulf company that must issue ZATCA e-invoices soon | Whichever has a local partner with live Saudi customers | Compliance depends on the partner's experience |
| Manufacturer or distributor with complex stock | All three, tested with your own bills of materials | Depth varies by process, so demos must use your data |
| Company expecting heavy customisation | Weigh the upkeep cost in each | Custom work must be maintained and upgraded in any of them |
Neither is better in general. ERPNext's software is free and Frappe Cloud is priced by use, while Odoo has a free edition, per-user plans for the paid one and a wide app catalogue. Test both against your own scenarios.
It depends on scope, users and partner. Odoo publishes its plans, while Business One is typically quoted through partners, so compare written quotes for the same scope over several years.
None can be named without your details. Check each vendor's current ZATCA support, your wave and a local partner's references.
SAP positions it for small and midsize businesses. Whether it fits your budget is a question for a partner quote.
Odoo Community is open source under the LGPL v3. Enterprise is shared source under a proprietary licence.
If Odoo is on your shortlist, read what Odoo is, then choose an edition with Odoo Community vs Enterprise. When you are ready to extend it, browse Odoo modules, and if you build modules yourself, you can sell them on DevMarket.
Compare the three Odoo hosting options from Odoo documentation: what each allows, who runs what, which editions fit, where data sits, what costs to expect and how to move between them.

An Odoo implementation is a project, not an installation. Follow the phases from scope to go-live, see who does what, decide between a partner and doing it yourself, and use a go-live checklist.
