Odoo vs Unit4.
Which Unit4 do you mean?
"Odoo vs Unit4" is really two comparisons, because Unit4 split. Unit4 itself is now an enterprise ERP for people-centric service organisations - strong for large professional-services firms, with enterprise implementation budgets to match. The products most Dutch SMBs mean by "Unit4" - Multivers and Boekhoud Gemak - left the company: Exact acquired Unit4 Bedrijfssoftware and continues them as Software Gemak. If you are a large services organisation, Unit4 ERPx is a serious option in a different league. If you are an SMB on Multivers wondering what your future platform is, that is the real question - and there Odoo is the interesting answer: finance on the same platform as CRM, orders, inventory, projects, production and webshop. In one line: Unit4 went enterprise. Your Multivers install did not - and it deserves a future, not just a new label.

Five questions that decide it
Which Unit4 are you actually comparing?
Odoo serves the segment most "Unit4" searchers are in: Dutch SMB and mid-market businesses that ran Multivers or Boekhoud Gemak and want one platform for the whole operation.
Unit4 today sells ERPx, enterprise software for people-centric service organisations. The SMB packages that made the brand familiar in the Netherlands - Multivers, Boekhoud Gemak - were acquired by Exact and continue as Software Gemak.
First decide which comparison you are in. For a large services firm, Unit4 ERPx is real competition. For an SMB on Multivers, the comparison is about your next platform.
Enterprise weight versus mid-market agility
Odoo implementations for SMBs run weeks to a few months, priced per user, with standard apps you extend where it counts. You can start with three apps and grow.
Unit4 ERPx is bought and implemented like enterprise software: longer projects, bigger budgets, more governance. That weight is justified at enterprise scale - and oversized below it.
Match the weight of the system to the weight of the organisation. Most SMBs need agility more than enterprise governance.
Services depth versus business breadth
Odoo covers projects and timesheets well, but its real pull is breadth: the same platform runs trade, inventory, production, webshop and service - the things service-only suites leave to other tools.
Unit4 is genuinely strong where people are the product: professional services, project accounting, resource planning, HR. If that is your whole business, the depth is valuable.
A pure services organisation can justify a people-centric suite. The moment goods, stock or production enter the picture, breadth wins.
The Multivers question: a future, not just a new label
Migrating to Odoo replaces the aging install with a platform in active development: yearly releases, a growing app ecosystem and the operation - not just the books - on one model.
Multivers users have been through name changes and ownership changes; the product continues as Software Gemak under Exact. Continuity, but also a legacy codebase with its roots in the on-premise era.
If you have to think about the future of your package anyway, think once - and decide what the next ten years should look like.
Openness and total cost
Odoo is open source with per-app, per-user pricing and a broad partner ecosystem - you can see the code, extend it deliberately, and switch partners without switching platforms.
Unit4 pricing is enterprise-style: negotiated, opaque from the outside, and tied to implementation partners at enterprise rates. Fine at enterprise scale; hard to justify below it.
For SMB and mid-market, transparent per-user pricing plus an open platform is the cost profile that scales with you instead of ahead of you.
