The staffing spreadsheet is the real incumbent at most 5–50 person engineering firms. It got you here. Here's an honest look at where it stops scaling — and what replacing it actually involves.
The short version
Excel is genuinely good at what made you build the spreadsheet: it's flexible, everyone knows it, and it costs nothing extra. For a firm of a few people with a handful of projects, it can be the right answer.
It breaks in a specific, predictable way: the moment several PMs share one staffing plan across many projects. One editable master copy, hours re-typed between timesheets and forecasts, formulas that fail silently, and utilization reports that take an afternoon to assemble and are stale by the meeting. Independent research has repeatedly found errors in the majority of complex operational spreadsheets — and a staffing model with live rates is exactly that.
ProConsultHQ replaces the staffing workbook, the forecast workbook, and the pipeline tracker with one live system — and still exports to Excel whenever you want the grid back.
| Excel / Google Sheets | ProConsultHQ | |
|---|---|---|
| Cost | "Free" — plus the hours someone senior spends maintaining it every week | $35/user/month ($28 annual); free Solo plan |
| Staffing across projects | One master workbook; manual conflict-spotting; version collisions | Live resource forecast across every project and pursuit, with over-capacity flagged automatically |
| Schedule logic | Dates in cells; dependencies live in someone’s head | Work-plan Gantt with dependencies, lag, critical path, and violation warnings |
| Forecast vs. actuals | Actual hours re-keyed from timesheets, whenever someone has time | Logged time flows into the forecast; Budget / JTD / ETC / EAC / variance stay current |
| Pipeline in the plan | Separate BD tracker; wins arrive as staffing surprises | Pursuits carry probability-weighted hours directly in the capacity plan |
| Error risk | Silent formula and paste errors; no audit trail | Computed rollups with an activity log; numbers trace back to the work plan |
| Utilization reporting | Hours of assembly; stale on arrival | Live utilization by person and team; export to Excel in one click |
| Multi-user editing | Lock conflicts, or a shared sheet everyone fears breaking | Role-based access — PMs plan their projects, principals see the whole firm |
| Onboarding a new hire into the system | Tribal knowledge and a tour of the tabs | They log in and see their week, their tasks, and their timesheet |
4+ hrs/wk
A typical ops lead or principal at an 8–30 person firm spends half a day or more each week assembling staffing, utilization, and pipeline views by hand.
2–3 weeks
The typical staleness of the numbers decisions get made on, by the time data is collected, merged, and distributed.
$150+/hr
The billable rate of the person doing that assembly. At 4 hours a week, that's over $31,000 a year of senior time spent formatting cells.

Yes — every major view (forecast, financials, reports, time) exports to Excel/CSV. The goal isn't to take the grid away from you; it's to stop the grid from being the system of record.
ProConsultHQ has a built-in bulk import: bring your people and projects across from a spreadsheet in minutes, then build work plans on top. Most firms are running the same day — no implementation consultant, no multi-week onboarding program.
Those are real alternatives and each fits someone — see our ProConsultHQ vs. Monograph comparison. The short version: ProConsultHQ is the one built specifically for consulting engineering firms, with scheduling and earned-value forecasting depth at a self-serve price.
Free for one user on the Solo plan; $35 per user/month ($28 on annual) for teams, with no seat minimums. See pricing.
