The verdict in three sentences
An 18-person architecture firm loses its margin in phases that overrun, not in projects it turns down: with an average 18% overrun on planned hours, a third of projects become loss-making before anyone notices in construction administration. Off-the-shelf tools such as Monograph or Deltek cost roughly 35 to 90 USD per user per month, 7,560 to 19,440 USD a year for 18 people, and are enough if your fee structures are standard. A custom tool at 60,000 to 120,000 USD in New York, or 35,000 to 65,000 EUR in Strasbourg, delivered in 3 to 4 months, makes sense when you mix public work, private development, joint ventures and frequent additional services.
What practice management software must track
In the US, fees follow AIA phases (SD, DD, CD, bidding, CA); in France, they follow the public procurement mission elements known as loi MOP. In both cases each phase carries a share of the fee and should carry an hours budget.
| Phase (US / France) | Indicative fee share | Typical overrun (2026 estimate) | What the software must show |
|---|---|---|---|
| Pre-design / ESQ | 5 to 7% | +10% | Unpaid competition or sketch hours |
| Schematic design / APS | 8 to 15% | +15% | Client iterations counted |
| Design development / APD | 12 to 20% | +20% | Budget vs actual per team member |
| Construction documents / PRO | 18 to 35% | +22% | Consultant coordination hours |
| Bidding / ACT | 5 to 7% | +8% | Bid analysis |
| Construction administration / VISA-DET | 20 to 30% | +25% | Site time, meetings, reports |
| Closeout / AOR | 4 to 6% | +30% | Endless punch lists |
The software has to cross three data points: fee per phase, budgeted hours and hours logged weekly. An alert at 80% of the hours budget lets you request an additional services amendment before working for free.
Monograph, Deltek or custom: costs compared
| Criterion | Monograph-type tool | Deltek-type ERP | Custom build (New York) | Custom build (Strasbourg) |
|---|---|---|---|---|
| Initial cost | Minimal setup | 5,000 to 20,000 USD implementation | 60,000 to 120,000 USD | 35,000 to 65,000 EUR |
| Annual cost (18 users) | About 7,500 to 12,000 USD | About 12,000 to 20,000 USD | 10,000 to 18,000 USD | 5,000 to 10,000 EUR |
| Time tracking by phase | Yes | Yes | Yes, with sub-phases | Yes, with sub-phases |
| Progress billing | Standard model | Advanced | Your exact rules | Your exact rules |
| Additional services | Basic | Full | Full, with client history | Full, with client history |
| Integrations | Vendor catalogue | Broad | Accounting, Revit, calendar | Accounting, Revit/ArchiCAD |
| Time to go-live | 2 to 4 weeks | 2 to 4 months | 3 to 4 months | 3 to 4 months |
Over 5 years, a subscription for 18 users costs 40,000 to 120,000 USD including implementation, close to a custom build. The decision depends on how unusual your workflow and billing really are.
Indicators a principal should see every Monday
| Indicator | Alert threshold | Action |
|---|---|---|
| Hours used vs phase progress | More than 10 points gap | Project review, amendment |
| Billable utilisation | Below 70% | Review unassigned time |
| Unbilled work in progress | Over 45 days | Issue the invoice |
| Client payment delay | Over 60 days | Reminder, late fees |
| Project margin | Negative at end of CDs | Partner decision |
Mini case study
Camille, managing architect of an 18-person practice in Strasbourg, bills 1,600,000 EUR in fees a year and budgets about 18,000 production hours. With an 18% overrun she uses 21,240 hours. Bringing the overrun down to 10% through alerts and timely amendments saves 8% of 18,000, or 1,440 hours, at a loaded cost of 55 EUR: 79,200 EUR. Amendments requested on time bring in about 40,000 EUR more. On a 50,000 EUR custom tool, payback comes in 5 to 6 months, provided the team logs time every week. A New York firm with similar volume and loaded costs near 95 USD per hour recovers a 100,000 USD build in a comparable timeframe.

FAQ
How much does architecture practice management software cost?
In 2026, subscriptions such as Monograph or Deltek range from about 35 to 90 USD per user per month. A custom tool costs 60,000 to 120,000 USD in New York or 35,000 to 65,000 EUR in Strasbourg, plus 10 to 15% a year of maintenance.
Does it handle fee phases?
Yes, each project is split into AIA phases or French mission elements, each with a fee percentage and an hours budget. Private commissions can follow a different breakdown.
How do we make sure staff log their hours?
A weekly entry under 5 minutes on mobile plus an automatic Friday reminder works for most firms. Compliance then exceeds 95%.
Can billing follow project progress automatically?
Yes, the software computes the invoice from the progress percentage validated for each phase. Unbilled work in progress often drops by 30 to 45 days.
How long does implementation take?
2 to 4 weeks for a lightweight subscription tool, 2 to 4 months for an ERP, 3 to 4 months for a custom build. Migrating ongoing projects usually takes 1 to 2 weeks.
