What the cheat sheet actually compares
The PDF is our own short comparison, not a vendor price list and not an independent benchmark. It lines up five systems the way we explain them to South African SMEs: Odoo (Community and Enterprise), NetSuite, SAP Business One, Microsoft Dynamics 365 and Oracle ERP Cloud. The estimate column below is printed in that PDF. It is not a quote from those companies, and it is not our implementation fee. For our work, contact us for a quote, or read the ranges already published on the ERP implementation page.
| System | Who the sheet says it fits | Estimate printed in the PDF | Customisation, in our words |
|---|---|---|---|
| Odoo Community / Enterprise | Growing SMEs that want modular apps and the option to self-host. | Community core is free. The sheet lists Enterprise around $39 to $59 per user per month before hosting. | Community can be self-hosted and extended in Python. That is the path on our Konstructo work. |
| NetSuite | Mid-market companies with standardised finance and inventory processes. | The sheet lists a start around $1,400 per month, plus user licences and implementation. | The sheet treats custom work as expensive and easy to get locked into. |
| SAP Business One | Small and midsize manufacturers and service firms that want deep inventory. | The sheet lists a start around $410 per user per year, plus heavy implementation. | Capable, and it needs trained staff or specialist consultants. |
| Microsoft Dynamics 365 | Wholesale and distribution businesses already living in Microsoft 365. | The sheet lists Essentials from about $70 per user per month, plus implementation. | Strong where Office and Teams already are. The sheet notes extra add-ons for gaps. |
| Oracle ERP Cloud | Large enterprises with international volume. | The sheet lists a base around $150 per user per month, aimed at enterprise use. | More system than a growing SME usually needs. |
Why the sheet argues with "never customise"
Closed suites often charge heavily to change a workflow, and a cloud update can break that change. Odoo Community is the opposite bet in the sheet: you host it, you can read the code, and there is no per-user licence on the core. AI-assisted coding can speed up a Python module. It does not remove the need to extend standard models, keep dependencies clear, and test upgrades on staging. That caveat is also on our ERP page.
Read the longer versions before you treat the table as a decision: when a rigid ERP pitch fails an SME, Odoo versus custom development, and one suite versus best-of-breed apps. Where Odoo was the wrong tool, we built RentFlow instead of forcing it.
The five-step self-host roadmap in the PDF
- Map the core process. Do not copy every spreadsheet step. Write down the workflows that earn their place, then match them to standard Odoo apps such as CRM, accounting, inventory or manufacturing.
- Set up Community. Deploy Odoo Community on infrastructure you control, so the database is yours and you are not stuck on Enterprise hosting you do not need.
- Use existing add-ons first. Look for a maintained community module before writing code for tax, shipping or a report.
- Customise the edge. Python modules only where the workflow is actually how you win work. We test those on staging.
- Go live in phases. CRM and accounting first. Manufacturing, field service or extra reporting after the first users are stable.
That is the same sequence we use on implementation projects. The email form still sends the PDF if you want it offline. Nothing above is withheld behind the form.
