You want one clear picture of finance and stock, but “SAP” is not one product. The useful answer before any comparison is to name what you would actually receive: SAP Business One or S/4HANA Cloud Public Edition, and on the Odoo side which release and which plan. Then you compare two like-for-like scopes, and meeting time turns into a clear decision.
At ToDoOps we implement Odoo for Saudi businesses. This guide explains the difference between the two SAP products as SAP’s own pages present them, then builds a fair comparison around one scenario.
What does “SAP” mean in the proposal in front of you?
SAP Business One is an ERP for small and midsize businesses: finance, purchasing, inventory, sales, CRM and reporting, offered in the cloud or on-premise. S/4HANA Cloud Public Edition sits within SAP Cloud ERP and covers finance, supply chain, HR and sales with preconfigured practices on a cloud subscription.
These are different products. Running Business One in the cloud or on-premise does not make it the same as public-cloud S/4HANA, and capabilities described on the S/4HANA page do not transfer to Business One. Private-cloud and on-premise options for S/4HANA need a separately specified proposal and are not assumed to match the public edition. Ask the vendor for the product name, deployment type, users and add-ons.
And the Odoo side?
The Odoo 19 documentation gives a fixed functional reference for each app. The current Standard and Custom plans include apps per user per plan, not per app. Studio, multi-company and the external API come with Custom, Odoo.sh hosting is an additional cost, and implementation sits outside the subscription. Hosting mode (Online, Odoo.sh or on-premise) depends on the plan, and custom code has restrictions on cloud hosting, so confirm these before you rely on a customization.
Map your business before you ask about price
Write down your entities and operations: sales, purchasing, stock, whether you have manufacturing or projects, and how you expect to grow over the coming years. Do not use headcount as a hard cut-off, since a small manufacturer with complex production can need more than a larger services firm. Not every SAP solution is expensive or slow, and Odoo is not cheaper by a fixed percentage or faster by a fixed duration. The difference shows up in a written scope.
For Odoo, we analyse your needs and define configuration, agreed development, migration, training and support. Compare that scope with the SAP partner’s proposal using the same workflow.
A shared acceptance example: an order of 12 units
This hypothetical scenario can be proposed to each vendor. It assumes invoicing based on delivered quantities:
| Status | Quantity |
|---|---|
| Confirmed in the order | 12 |
| Delivered and validated | 8 |
| Outstanding | 4 |
Ask each vendor to show you three things on your data. First, the effect of the validated delivery on stock: eight units left and the balance is correct. Second, that sales can see the remaining four on the same order. Third, how an invoice for the eight delivered units is prepared under the assumed policy, keeping the draft, posting and payment as separate stages. This shows how each system handles partial delivery, and what reaches finance and at what moment.
To try a similar path in Odoo before the meeting, try Odoo interactively: a guided simulation with fictional data for a sales and stock path. It is not a live system and not a trial of SAP. To see the apps and sectors: Odoo apps and industries.
Compare the full commitment on the same basis
Fix the period, currency and VAT treatment, and separate implementation from subscription, hosting and support. Count each item once, so training or migration is not counted twice within the same proposal total. Do not rely on generic discount percentages or ready-made timelines; each needs a scope and inputs.

Frequently asked questions
Is SAP one product? No. It is a family of products. SAP positions Business One for small and midsize businesses, while S/4HANA Cloud Public Edition sits within SAP Cloud ERP.
Is Business One the same as S/4HANA? No. Each has its own page and scope, and features do not carry over from one to the other.
Can we start with a first phase only? Yes, if the scope and data sequence are clear, for example sales, stock and finance first and the rest afterwards.
Can our current system stay? It can, and connect to the new one if it is specialized. Write down the integration boundary and the data owner before agreeing.

The next step
Name the product and deployment type on each side, then ask each vendor to run the 12/8/4 order on your data.
