The verdict in three sentences
An architecture firm loses margin not on its stated fees but on unbilled time and poorly tracked phases. An off-the-shelf tool (80-250 EUR/month/user) fits a 2-6 person practice; a custom platform (25,000-55,000 EUR) pays off once you must connect BIM, accounting and a client-owner portal. The real win isn't the software: it's 8-12 margin points recovered through rigorous time tracking.
What a firm's software must cover
Managing an architecture firm looks nothing like standard accounting or a generic CRM. It follows the rhythm of project design phases (schematic, detailed design, construction docs, tender, supervision) and splits each engagement into progressive fees, funding calls and site supervision.
| Module | Role | Profitability impact |
|---|---|---|
| Engagement management | Project, phase and progress tracking | Core steering |
| Design phases | Fee split by phase | Bill at the right moment |
| Time entry | Hours per project and per person | +8 to 12 margin pts |
| Fees & funding calls | Schedule, reminders | -30 to 45 days payment delay |
| Plan & document DMS | Versioning, DWG/PDF, distribution | Zero lost version |
| Client-owner portal | Approvals, site reports | -40% emails |
Without time entry, a firm believes it earns money on a project that, once real hours are counted, comes out at a loss. It is the number-one margin leak.
Off-the-shelf vs custom: the numbers
| Criterion | Off-the-shelf tool | Custom build |
|---|---|---|
| Entry price | 80-250 EUR/month/user | 25,000-55,000 EUR |
| 3-year cost (5 users) | 14,400-45,000 EUR | 30,000-62,000 EUR |
| Time to launch | 2-6 weeks | 3-5 months |
| Native project phases | Yes (standard) | Yes (firm-tailored) |
| BIM / Revit sync | Limited | Custom |
| Accounting sync | Export | Real-time integration |
| Client-owner portal | Basic | Premium, branded |
| Code ownership | No | Yes |
As a 2026 order of magnitude, off-the-shelf wins for a small single-office firm. Custom becomes relevant for the multidisciplinary agency (architecture + engineering + planning) wanting a single flow from BIM to accounting with no re-keying.

Marc, a partner architect in a 6-person firm in Nantes, bills roughly 480,000 EUR in fees/year. Before any tool he estimated hours by gut feel and delivered 3 in 10 projects below break-even.
After deploying accurate time tracking (off-the-shelf at 180 EUR/month/user, i.e. 12,960 EUR/year), he recovers 9 margin points on his turnover: 43,200 EUR of extra margin. First-year net ROI: 43,200 - 12,960 = 30,240 EUR. The software pays for itself in under four months.
FAQ
Does off-the-shelf really handle project phases? Yes, serious industry tools include phase splitting as standard. Allow 2-6 weeks of setup to match your fee rates per phase.
When does custom pay off? Beyond 8-10 staff, or when you want real-time BIM + accounting sync. Below that, off-the-shelf at 14,400-45,000 EUR over 3 years stays more rational.
How long to recoup the tool? With 8-12 margin points recovered, most firms break even in 3-6 months. The key factor is time-entry discipline, not the software itself.
Can the software connect to the client-owner portal? Off-the-shelf often ships a basic extranet. For a premium branded portal with report approvals, you need dedicated development (counted within the 25,000-55,000 EUR).
What about my DWG plans and versions? A DMS with versioning avoids lost versions, a major source of on-site errors. Check DWG/IFC support and distribution traceability.
