The verdict in three sentences
A custom fee-management application for an Amsterdam architecture firm costs, in 2026, between 30,000 and 70,000 EUR net, delivered in 4 to 6 months, with progress tracking, fee calls, time capture and per-project profitability. Profitability tracking often reveals 10 to 20 % of margin lost on underestimated phases (concept, design development, construction). Plan for an accounting integration (Sage, QuickBooks) and 10 to 15 %/year maintenance.
Why per-project profitability escapes firms
Architecture fees are split into phases, often billed on progress. Without a dedicated tool, time spent is not reconciled with fees phase by phase, and margin melts on underestimated phases before anyone notices in time.
| Element | Without dedicated tool | With custom 2026 |
|---|---|---|
| Per-phase progress tracking | Rough estimate | Tracked % complete |
| Time/fee reconciliation | Absent or late | Real-time per project |
| Fee calls | Manual, frequent misses | Auto-generated |
| Overrun detection | End of project | Mid-phase |
| Lost margin detected | Invisible | 10-20 % recoverable |
| Partner reporting | Monthly Excel | Live dashboard |

| + Partner dashboard + forecasting | 58,000 - 70,000 EUR | 6 months | 15 % |
| Accounting integration (Sage/QuickBooks) | 5,000 - 12,000 EUR | included | - |

Julia, partner at a 12-person architecture firm in Amsterdam, manages 25 active projects for 2.4 M EUR in annual fees. Profitability tracking reveals that 15 % of margin is lost on underestimated design-development and construction phases, roughly 360,000 EUR of poorly steered value. By recovering just a third through better overrun detection and justified variations, the firm regains 120,000 EUR of annual margin. Against a 55,000 EUR investment plus 7,000 EUR maintenance, the return is achieved in under a year.
FAQ
Does it replace my accounting software? No. The application steers project profitability and integrates with your accounting (Sage, QuickBooks) to avoid double entry and keep figures reliable.
How is time captured? Via a simple interface, ideally mobile, so each team member logs hours per project and phase in seconds.
Can it handle progress-based fee calls? Yes: the tool triggers calls based on each phase's percentage complete, with automatic reminders to reduce late payments.
How long to deploy? From 4 to 6 months depending on scope. A progress + fee-calls core can ship in 4 months.
What maintenance budget? Plan 10 to 15 % of development cost per year, i.e. roughly 3,000 to 10,500 EUR/year depending on scope.
