Short answer: there is no best software for every installation company - there is a best choice per profile. A small team that mainly wants rid of paper work orders is fine with a light app. An installation company deep into service and maintenance often picks an industry package. And whoever wants to connect the whole company - from quote to engineer to invoice to webshop - ends up at a broad platform. Below, seven packages commonly chosen in the Dutch market, honestly side by side, including the one we sell ourselves (bias disclosed where it applies).
At a glance
| Package | Type | Strongest point | Watch out |
|---|---|---|---|
| Syntess Atrium | Industry ERP for installers | Depth in installation, service and maintenance | Vertical and closed; recently “Powered by Aceve” |
| OpusFlow | All-in-one for (sustainable) installers | Popular with solar and heat-pump installers | Younger product; verify depth per process |
| AFAS | Broad Dutch ERP | Finance, HR and payroll in one | Field service and work orders are not the core |
| Exact Construction & Installation | Accounting + industry layer | Strong Dutch accounting core | Thinner in engineer planning and service |
| 4PS Construct | Construction ERP on Microsoft | Project-based construction, Microsoft stack | Enterprise weight; heavier project |
| Simple-Simon | Work-order app | Live fast, low threshold, cheap | Only the work order; everything else stays put |
| Odoo + RogerDone | Open platform + dispatch board | Everything connected, CRM through accounting, plus smart engineer planning | Standard planning is basic - hence RogerDone |
The seven packages, discussed honestly
Syntess Atrium has been the reference in the installation industry for decades: work orders, maintenance contracts, project control and quoting in the installer’s own language. That depth is real. The flip side: it is a vertical, closed package - the moment you want a webshop, customer portal, CRM as a growth engine or broad reporting, you end up in integrations. And since the company presents itself as “Syntess - Powered by Aceve”, there is an extra reason to pay attention: a new owner means questions about roadmap, pricing and support. The full trade-off sits in our Syntess alternative overview and the 1-on-1 comparison Odoo vs Syntess.
OpusFlow positions itself as an all-in-one platform for installers, with strong traction among sustainable-installation companies (solar, heat pumps, charging stations). Strong marketing and pace. It is a younger product than the established names: verify per process (quoting, inventory, accounting) whether the depth is there for your company, and ask for references in your sub-sector.
AFAS is a broad Dutch ERP with finance, HR and payroll at its heart. A logical candidate when the administrative side is your biggest pain - but field-service planning and work orders are not the core, so a second package often lands next to it anyway.
Exact Construction & Installation builds on the strongest Dutch accounting core in the SMB market, with an industry layer for construction and installation. Same pattern as AFAS: strong where it comes from (finance), thinner in engineer planning and service execution.
4PS Construct is a serious construction and installation ERP on the Microsoft platform (Business Central). A logical candidate for larger, project-driven installation companies deep in the Microsoft stack - budget for an implementation with enterprise weight.
Simple-Simon is the lightest of the list: a work-order app that goes live fast and costs little. Fine for a small team getting off paper. But the app only solves the work order - the order, stock, invoice and job costing still live elsewhere, and that is where the retyping starts. Why that is the real problem: digital work orders: the app is not the problem, and the direct comparison in Odoo vs Simple-Simon.
Odoo + RogerDone - and here we are a party, so read with that in mind. Odoo connects what usually lies scattered at installation companies: CRM, quotes, purchasing, inventory, work orders (Field Service), maintenance contracts, invoicing and accounting on one open platform. Honesty requires saying: the standard engineer planning is functional but basic. That is exactly why we built RogerDone, a smart dispatch board on top of Odoo that plans on skills, travel time and availability. The complete guide for this route: software for field-service installers.
Which one fits you?
- 1-5 engineers, paper is the problem → Simple-Simon or another light work-order app; keep it simple.
- Purely installation/service, deliberately in a vertical package → Syntess Atrium or OpusFlow; choose on references in your sub-sector.
- Administration and HR are the biggest pain → AFAS or Exact; accept that field service needs a second solution.
- Large, project-driven, Microsoft house → 4PS.
- Connecting service with sales, inventory, portal and finance → Odoo + RogerDone; book a free scan and we will say so honestly if a vertical package fits you better.
Frequently asked questions
What is the best software for an installation company? There is no best for everyone: light team → work-order app; deep into service/maintenance → industry package (Syntess, OpusFlow); connecting everything → Odoo + RogerDone. Choose on your centre of gravity, not the longest feature list.
What is a good alternative to Syntess Atrium? Staying in a vertical package: OpusFlow. Connecting wider: Odoo with RogerDone. Since the Aceve acquisition this is the moment many customers compare - see the full Syntess alternative overview.
What does software for an installation company cost? Light apps from roughly €10-20 per user per month; industry packages and ERP tens of euros per user plus implementation. Compare three-year totals.
Does an installation company need an ERP, or is a work-order app enough? Up to about five engineers with simple administration: an app suffices. Above that, retyping between systems costs more than integration.
Can Odoo run an installation company end to end? Yes, from quote to accounting; for smart engineer planning we complement the basic standard with RogerDone.
What does the Aceve acquisition of Syntess mean? Little in the short term; watch roadmap, pricing and support - and use the moment to re-test your choice.
