Odoo vs Isah.
Manufacturing ERP, or business platform?
Isah is a mature ERP for order-driven manufacturers - machine and equipment building, metal, project-based and engineer/make/configure-to-order - with strong credentials in engineering, work preparation, production and planning. It sits in the same league as Bemet, MKG and Ridder iQ, and is closest in profile to Ridder iQ. Two honest notes: there is very little public review data (one Capterra review, scoring 4.0), so this is a functional comparison, not a review score; and in our own experience the total cost of ownership and consultancy rates tend to run above average for this category, with rates that can exceed €170 per hour - worth checking in your own quote. Odoo gets more interesting when you want to do more than control production: connect the whole business - CRM, sales, eCommerce, customer portal, service, finance, BI and automation. In one line: Isah controls the manufacturing process. Odoo connects it with the rest of the business.
- 01 Order-driven manufacturing and engineering: this is Isah territory Don't talk loosely about 'Odoo also has PLM'. With an Isah prospect, probe CAD/PDM, revisions, release and change control concretely - and fit-gap honestly.
- 02 Cloud and browser-first: validate the reality Don't ask 'is there cloud'. Ask: do you work fully in a browser, or via a hosted app, client/server or remote desktop? That difference is huge for everyday users.
- 03 Integrations and an open platform A good question for an Isah user: which systems did you have to put next to Isah because it was not comfortable enough there?
- 04 CRM, eCommerce, portal and service: the edge or the core? Do you use Isah to process customer orders, or also genuinely to grow commercially and connect customers digitally? That is where the openings are.
- 05 Total cost and an open ecosystem Ask for a fully-loaded multi-year quote, and weigh how easily you could get an independent partner or change course later.

Five questions that decide it
Order-driven manufacturing and engineering: this is Isah territory
Odoo has Manufacturing (MRP), Inventory, Purchase, Quality and Maintenance on one data model, strong for SMB and mid-market production. But where engineering drives everything - CAD/PDM hand-off, revisions, release and change control, bills of materials that shift mid-project - that needs serious, deliberate configuration.
Isah is built for order-driven manufacturing, with an explicit strength in engineering: Isah Engineering exchanges data with CAD/PDM so engineering bills of materials flow into purchasing and production, and changes stay traceable within the project. For an engineering-led machine or equipment builder, that is a real strength.
Don't talk loosely about 'Odoo also has PLM'. With an Isah prospect, probe CAD/PDM, revisions, release and change control concretely - and fit-gap honestly.
Cloud and browser-first: validate the reality
Odoo is browser-first by design: one modern web UI from any browser, on any device, with portals and mobile access built in.
Many traditional manufacturing ERPs are functionally rich but not always cloud-native. The single public Capterra review even states "not ready for cloud", and names the Web API as a step toward the future. Treat that as a signal to verify, not a verdict.
Don't ask 'is there cloud'. Ask: do you work fully in a browser, or via a hosted app, client/server or remote desktop? That difference is huge for everyday users.
Integrations and an open platform
Odoo is open source: CRM, Sales, Website, eCommerce, Helpdesk and Accounting sit in one stack, plus an API, Python modules and a broad ecosystem to extend or connect quickly.
Isah offers a Web API as a step forward, but the one public review calls integration with popular software - CRM, for example - hard. As manufacturers grow they tend to want CRM, portal, BI, PDM, WMS, service and AI tooling connected.
A good question for an Isah user: which systems did you have to put next to Isah because it was not comfortable enough there?
CRM, eCommerce, portal and service: the edge or the core?
CRM, Sales, Website, Marketing and eCommerce sit in the same stack as ERP, plus a native B2B portal for order status, spare parts, service requests, documents and certificates - all on the same model as Sales, Inventory and Accounting.
Isah runs from first customer contact, but in practice "CRM" in a manufacturing ERP often means relationship and quote context rather than a modern commercial engine, and eCommerce or a customer portal are not the natural core.
Do you use Isah to process customer orders, or also genuinely to grow commercially and connect customers digitally? That is where the openings are.
Total cost and an open ecosystem
Odoo's total cost is usually lower, and the open-source model means a broad ecosystem of independent partners - so a second opinion, a different partner or a switch stays realistic.
In our own experience, the total cost of ownership - software, implementation, management and changes - tends to run above average for this category, with consultancy rates that can exceed €170 per hour. Services are largely kept in-house with few independent consultants, so you become strongly dependent on the software maker for every change. Treat this as practitioner experience, not an independent benchmark, and weigh how vendor-dependent you would be.

Which one fits?
Choose Odoo if…
- You want to connect sales and production, not only control the shop floor.
- You want CRM to become a real commercial engine - leads, pipeline, marketing, follow-up.
- You want to give customers online insight: a B2B or spare-parts portal, order status and documents.
- Service and aftersales are growing: helpdesk, field service, repairs and contracts.
- You want to work browser-first and keep integrations, API and AI open and fast.
- You want one platform and one source of truth instead of many tools next to the ERP.
Choose Isah if…
- You produce strictly to customer order in machine or equipment building.
- Engineering and CAD/PDM integration are central to your process.
- You value deep, manufacturing-specific industry knowledge above platform breadth.
- You mainly want to improve engineering, work preparation and production.
- You have little need for eCommerce, customer portals or marketing.
- You are comfortable with the current architecture and a more vendor-led model.
The best Isah alternatives
We are an Odoo partner, so we are not neutral about what we build. But honestly: for pure depth in project-driven production a specialist tool can be stronger. The difference is whether you want to connect production to the whole business.
| Alternative | Breadth (beyond production) | Project/manufacturing depth | Cloud & modern | CRM / eCommerce / portal | Open & extensible | Short verdict |
|---|---|---|---|---|---|---|
| OdooTop pick | Broad platform | Strong via Updoo building blocks | Yes, browser-first | Native | Open source | Best if you want to connect production to the whole business |
| Ridder iQ | Production-focused | Strong (metal/manufacturing) | Cloud available | Limited | Closed | Strong manufacturing specialist if you want to stay in a specialist tool |
| Bemet (Plan-de-CAMpagne) | Production & planning | Strong (planning) | On-premise heritage | Limited | Closed | Strong at production planning; narrower beyond it |
| MKG | Production-focused | Strong (metalworking) | Cloud available | Limited | Closed | Strong for metalworking; thin beyond the shop floor |
| Infor LN | Broad, enterprise | Strong (discrete manufacturing) | Cloud available | Via apps | Heavy, partner-dependent | Enterprise manufacturing; often too heavy for SMBs |
By profile: which alternative makes sense?
Concise per option, so the shortlist shrinks faster:
Odoo
Strongest if you want to connect your project-driven production to the rest of the business: CRM, sales, eCommerce, customer portal, service and finance on one modern, browser-first platform. For the ETO-specific parts (configurator for complex calculation, shop floor, project post-calculation) we build Updoo blocks on top of standard Odoo - without locking you into a closed add-on ecosystem.
Ridder iQ
A strong Dutch manufacturing specialist with deep production and calculation functionality. Logical if you want to stay in a specialist tool and your need is mostly on the shop floor and in calculation; beyond production (CRM, eCommerce, portal) it is narrower and more closed.
Bemet (Plan-de-CAMpagne)
Strong at production planning and scheduling for manufacturers. A good choice if planning is your biggest pain; beyond that thinner, with on-premise heritage and integrations that get harder on software that no longer develops.
MKG
An ERP for metalworking, strong in quoting, work preparation and post-calculation on the shop floor. Logical for pure metal companies; thinner beyond production and closed in its ecosystem.
Infor LN
An enterprise manufacturing ERP for larger, international discrete production. Powerful and deep, but heavy to implement, pricey and partner-dependent - often too much for the Dutch SMB manufacturer.
Why machine builders look for an Isah alternative
Isah earned its place with deep, project-driven production: calculation of complex orders, engineering, work preparation and post-calculation for machine building and engineer-to-order. The pain is usually beyond production and projects: CRM, sales, eCommerce, a customer portal and service are thin or missing, so a second system often runs alongside. On top of that the ecosystem is closed - integrations go through partners - and the client-server, on-premise heritage feels dated next to modern, browser-first software.
Specialist or platform? The honest trade-off
This is the heart of it, and we are honest about it. Isah, Ridder iQ, Bemet and MKG are deep manufacturing and project specialists. If you want to optimise your production further - the calculation, engineering and planning rituals a specialist tool has refined over years - a specialist can be stronger than a broad platform. Odoo wins the moment you want to connect production to the rest of the business: one data model from quote to work order to invoice, with CRM, webshop, portal and service native alongside. So the question is not "which is better", but: do you want to deepen production, or integrate the whole business?
Where Odoo matches the specialist: Updoo
The misconception is that a broad platform misses the manufacturing depth. For the parts where standard Odoo stops, we build Updoo blocks: a product configurator for complex calculation, a glove-friendly Shopfloor layer for the floor, and post-calculation that books hours and material back to the project. The difference with a closed add-on ecosystem: it is open source, you can read the code, extend it deliberately, and switch partners without switching platform.
How to choose
Three rules of thumb. One: if your pain is purely deepening project-driven production and you want to stay in a specialist tool, Ridder iQ, Bemet or MKG are the logical candidates. Two: if you want to connect production to CRM, sales, eCommerce, portal and finance on one modern platform, Odoo is usually the strongest choice, with Updoo for the ETO-specific parts. Three: if you are a large, international discrete manufacturer, an enterprise ERP like Infor comes into play. Start from where your biggest pain is, not from the feature list.

Control production, or connect the whole company?
Plenty of order-driven manufacturers rightly run a specialised ERP like Isah. It only gets interesting once sales, customer portal, service, finance, data and integrations weigh as much as production itself. Book a fit-gap call where we put your engineering, production, planning, CRM, portal and finance side by side against both Isah and Odoo - including an honest look at browser-first working, integrations and total cost.
The most expensive software is the software that 'just works'.
Because the work around it - double entry, Excel checks, waiting time, errors - never shows up on your software invoice. It does land on your P&L, as labour cost and lost hours; you just never add it to the software bill. And the frustration your team feels every day stays completely invisible. Work out what it costs you per year: you can't capture work satisfaction in a spreadsheet. 60 seconds, no sales pitch - just a number that sticks.
