The verdict in three sentences
A 28-person New York architecture practice that does not track hours by design phase typically loses 2 to 4 points of margin without knowing where. A practice management SaaS at 50 to 110 USD per user per month is enough if your workflows are standard, while custom software at 40,000 to 80,000 USD (2026 ballpark) makes sense once percent-complete billing, consultants and change orders carry real weight. Either way, the goal is identical: see margin by project and by phase every week, not once a year at year-end close.
Why the SD to CA phases hide your losses
Most US owner-architect agreements, based on AIA contract documents, split the basic fee into phases. Every principal knows the pattern: hours rarely overrun on schematic design, almost always on construction documents and construction administration, when the job site drifts. Without time entries tied to a phase, the annual spreadsheet blends everything, and the firm discovers that a multifamily project swallowed the margin of a school renovation.
| Phase | Typical fee share | Observed hour overrun (ballpark) | Main risk |
|---|---|---|---|
| Schematic Design (SD) | 15 % | 0 to 10 % | Free iterations, competitions |
| Design Development (DD) | 20 % | 10 to 20 % | Owner program changes |
| Construction Documents (CD) | 40 % | 15 to 30 % | Redraws, consultant coordination |
| Bidding / Negotiation | 5 % | 5 to 15 % | Value engineering rounds |
| Construction Administration (CA) | 20 % | 20 to 40 % | Schedule slips without additional services |
| Additional services | Hourly | Often unbilled | Scope creep never invoiced |
With 45 active projects, the principal needs three numbers per project: hour budget by phase, hours consumed, billable percent complete. Everything else follows: progress billing, overrun alerts, and the backup to negotiate additional services.
SaaS or custom: compare over 3 years
Specialized SaaS tools for architecture firms handle timesheets, phase tracking and invoicing well. They struggle with common New York cases: joint ventures with fee splits, consultant pass-through billing with markup, additional services, and exports to an outside CPA with its own chart of accounts.
| Criterion | Specialized SaaS | Custom software |
|---|---|---|
| Upfront cost | 0 to 4,000 USD setup | 40,000 to 80,000 USD |
| Recurring cost, 28 users | 16,800 to 36,960 USD per year | Hosting and maintenance quoted |
| 3-year total (estimate) | 50,000 to 115,000 USD | 50,000 to 100,000 USD |
| Time to go live | 2 to 6 weeks | 3 to 5 months |
| AIA phases and additional services | Standard, limited flexibility | Modeled on your contracts |
| Joint ventures and consultants | Often limited | Automatic fee split |
| Data ownership | Export per vendor terms | Database you own |
The three-year comparison is tighter than most principals expect. The right criterion is not price, it is the number of exceptions your firm handles every month. Past a dozen spreadsheet workarounds, the SaaS becomes one more tool to reconcile.
What version one must do
A useful first version fits in five modules. Weekly time entry by project and phase, on desktop and mobile, under 3 minutes per person. Hour budgets by phase, derived from the fee and a blended loaded rate. Percent-complete billing with monthly invoices and collections tracking. A margin dashboard by project, refreshed every Monday. Change order support: when CA exceeds budget by 20 %, the tool assembles the numbers to justify additional services.
Expected integrations in New York: QuickBooks or another accounting export, calendar sync, and optionally payroll to pull the true cost of each employee. Privacy obligations are light, since the data is mostly internal time.

Rachel, principal of a 28-person practice in Brooklyn, bills 4,200,000 USD in fees per year. Blended loaded rate: 95 USD per hour. On a 60-unit residential project with 600,000 USD in fees, CA represents 120,000 USD, about 1,260 budgeted hours. The schedule slipped four months and the team logged 1,650 hours: 390 hours over, or 37,050 USD of lost margin on a single phase.
With weekly tracking, the alert would have fired at 80 % of budget, while additional services could still be negotiated. If the firm recovers 2 points of margin on its fee revenue thanks to these alerts, the gain reaches 84,000 USD per year. A 65,000 USD custom build pays back in under 10 months, a SaaS at 75 USD per user (25,200 USD per year) in under 4 months, provided it really covers your joint venture cases.
FAQ
How much does architecture practice management software cost in 2026?
Specialized SaaS runs 50 to 110 USD per user per month, roughly 17,000 to 37,000 USD per year for 28 people. A custom tool is in the 40,000 to 80,000 USD range depending on modules.
How long does it take to go live?
Allow 2 to 6 weeks for a SaaS and 3 to 5 months for a custom build, including migration of active projects. Time entry can start in month one, before dashboards are ready.
Will staff actually log their hours?
Yes, if entry takes under 3 minutes a week and is prefilled from calendar projects. Firms that pair entry with an automatic Friday reminder usually reach more than 90 % complete timesheets.
Can it handle joint ventures and consultant billing?
A custom tool splits fees between partners phase by phase and handles consultant pass-through with markup. Many SaaS tools only model the lead firm, which forces parallel spreadsheets.
What return should we expect?
Recovering 1 to 2 points of margin on 4.2 M USD in fees means 42,000 to 84,000 USD per year. That is the range that justifies the investment for most firms above 20 people.
