The verdict in three sentences
Custom management software for an Amsterdam creative agency costs EUR 35,000 to 80,000 in 2026, with EUR 500/month maintenance. It drives projects, time tracking, per-client profitability and billing in a single flow, where suites (Teamwork, Productive) charge EUR 18-35/user/month and box in your model. The switch to custom pays off beyond 15-18 staff or when client margin becomes your vital metric.
What custom costs in 2026
| Module | Function | 2026 price (EUR) |
|---|---|---|
| Project management | Tasks, milestones, resources | 12,000 - 18,000 |
| Time tracking | Timesheets, project allocation | 7,000 - 13,000 |
| Per-client profitability | Margin, budget burn, alerts | 9,000 - 17,000 |
| Quotes & billing | Estimates, invoices, deposits | 7,000 - 16,000 |
| Leadership dashboard | Real-time agency KPIs | 5,000 - 9,000 |
| Total platform | 35,000 - 80,000 |
Timeline: 4 to 8 months. Maintenance EUR 500/month. Hosting EUR 100-200/month.
Suites vs custom: the threshold
| Staff | Suite EUR 28/user/mo (yr) | Custom EUR 57,000/4 yrs + maintenance | Verdict |
|---|---|---|---|
| 8 | 2,688 | 20,250 | Suite wins |
| 15 | 5,040 | 20,250 | Suite still ahead |
| 25 | 8,400 | 20,250 | Suite ahead on cash, but... |
| 40 | 13,440 | 20,250 | Break-even |
| 60 | 20,160 | 20,250 | Custom wins |
On licence cost alone, the suite stays cheaper for a long time. Custom is justified mainly by recovered margin: automating profitability tracking often gains 2 to 5 margin points, far more than the cost gap.
Mini case study
Lars, director of a creative agency in Amsterdam (22 staff, EUR 2.1M revenue), tracked profitability in Excel three weeks late. He invests EUR 58,000 in custom software with real-time per-client margin. Amortised over 4 years: EUR 14,500/year + EUR 6,000 maintenance = EUR 20,500/year. By spotting unprofitable clients in month 2, he recovers 3 margin points on EUR 2.1M = EUR 63,000/year. ROI in the first year.
