You already rejected ERP migration. Here's what your actual options are — and what each one costs in time, money, and disruption.
The standard advice for getting project-level margin visibility is "implement a PSA." That advice ignores what PSA implementation actually costs: $50,000–$400,000 in year one, 4–9 months of disruption, and a behavioral change requirement for every billable person on your team. For firms under 100 people that aren't PE-backed and don't have a dedicated ops team to run an ERP project, that path is effectively closed.
This page compares the three real options for firms in the 15–100 person range who need to see project-level margin visibility without replacing QuickBooks, Xero, or their existing payroll stack.
| Spreadsheets | Full ERP Migration (BigTime / Kantata / Deltek) |
WorkPulse | |
|---|---|---|---|
| Time to First Report | Hours of manual assembly | 4 weeks – 9 months | 4 minutes |
| Year-One Cost | $20,000–$30,000 in labor overhead (20-person firm) | $50,000–$400,000 | $149 one-time or $199–$299/mo subscription |
| Replaces QuickBooks? | No | Yes — that's the disruption | No — layers on top |
| Team Behavior Change Required? | No (existing workflow) | Yes — every billable staff must log time in new system | Minimal — upload existing timesheet exports |
| Report Cadence | Monthly (best case) | Real-time (once live) | Weekly (every Monday) |
| Project Gross Margin | Manual calculation | ✓ Live per project | ✓ 13-week rolling |
| Billable Utilization | Manual compilation | ✓ Real-time dashboard | ✓ Weekly by employee |
| Client Concentration Flags | ✗ Manual | ✓ Configurable | ✓ Automatic |
| Realization Rate | ✗ Rarely tracked | ✓ Native | ✓ Included |
| Implementation Risk | Low | High (30–40% of ERP projects stall) | Very low |
| Accounting System Migration | None | Required | None |
| Data Source | Manual spreadsheet entry | Direct time entry in new system | CSV export from QuickBooks, Harvest, ADP, BambooHR |
| Payback Period | Immediate (labor cost is sunk) | 12–36 months | First report |
The hidden assumption behind "we'll just use spreadsheets" is that the labor to build and maintain those spreadsheets doesn't count. It does.
A 20-person consulting firm where one ops manager or project lead spends 8 hours per week assembling utilization data, reconciling timesheet exports, calculating project margins, and building the weekly or monthly report is spending $20,000–$30,000 per year in fully-loaded labor cost — before accounting for the errors that get caught after invoices go out.
The subtler problem: spreadsheet-based margin reports are always backward-looking. By the time the data is assembled and the report exists, you're looking at a project that's already over. The margin has already leaked. You can note it for next time, but you can't fix it.
Full ERP migration — BigTime, Kantata, Deltek Vantagepoint — is the right answer for firms that have genuinely outgrown their existing stack. The tell: your team already logs time somewhere consistently, you already have a functional billing workflow, and the constraint is that the system doesn't talk to itself.
For firms where the problem is "we don't know our margins and we need to fix that quickly," ERP migration introduces a bigger problem before it solves the first one. You need to:
The firms most likely to stall on ERP implementation are the ones who went in because they wanted margin visibility — and discovered that the path to margin visibility was 6 months of ops work. 30–40% of mid-market PSA implementations don't fully go live within the planned timeline.
WorkPulse is built on a different premise: your existing books already contain most of the data you need. The constraint isn't that the data doesn't exist — it's that it's never assembled into a weekly margin report automatically.
The approach: upload your timesheet exports (QuickBooks Time, Harvest, BambooHR, ADP, or a plain CSV), and WorkPulse computes gross margin by project, billable utilization by employee, client concentration risk, and realization rate — delivered every Monday. No new accounting system. No migration. No behavioral change requirement for your team.
The tradeoff: WorkPulse is a reporting layer, not a PSA. It doesn't handle time entry, resource scheduling, or invoicing workflow. If those are the constraints, BigTime or Kantata is the right tool. If the constraint is visibility — knowing your numbers week-over-week without a software project — WorkPulse is faster.
The Margin Diagnostic ($149, one-time) uploads 13 weeks of timesheet data and delivers a full AI analysis: project margin ranking, utilization trend, client concentration flags, and top recommendations — grounded in your actual numbers, not benchmarks.

Yes. WorkPulse layers on top of your existing QuickBooks, Xero, or payroll system — no migration, no new accounting infrastructure. You upload timesheet data as CSV or connect directly, and WorkPulse generates a 13-week rolling margin report every Monday. Your accounting stack stays exactly where it is.
Total first-year cost typically runs $50,000–$400,000 depending on platform. BigTime: $17,000–$56,000 year one (25 users). Kantata: $60,000–$150,000+. Deltek Vantagepoint: $80,000–$200,000+. Implementation timelines range from 4 weeks (BigTime) to 9+ months (Deltek, NetSuite). These estimates exclude the 1–3 months of parallel running during cutover.
WorkPulse: 4 minutes from upload to first report. Full ERP migration: 4 weeks to 9+ months before you have reliable data in the new system. Most firms run parallel systems for 1–3 months during cutover, meaning they're maintaining two operational workflows before getting the visibility they wanted.
A 20-person firm typically spends 6–10 hours per week on manual data assembly before the margin report exists. By the time the data is ready, you're looking at last month's performance on a project that already closed. WorkPulse automates the assembly so the report exists every Monday without manual work, and it covers the rolling 13 weeks so you can see trends, not just snapshots.
The clearest fit: management consulting, IT/MSP, architecture & engineering, marketing agencies, and accounting advisory firms in the 15–100 person range. These firms run multiple concurrent projects and need to know which clients and project types are actually profitable — but haven't crossed the revenue or complexity threshold where a full PSA implementation is justified.
No — and that's the point. WorkPulse is a reporting and visibility layer, not a PSA or ERP. It doesn't handle time entry, resource scheduling, or invoicing workflow. WorkPulse is for firms that already have a time-tracking system and just need to turn that data into weekly margin intelligence — without a 6-month software project.
