Most MSPs know their PSA's monthly seat cost. Almost none have calculated the full cost of their PSA — which is why so many operators are surprised by the economics when they actually run the numbers before a migration decision. The direct cost (license fee) is the smallest component. The indirect costs — administrator time, technician inefficiency from a poor interface, custom reporting labor, integration maintenance — typically run 3-5x the license cost.
Direct PSA costs are straightforward: seat licenses at the published rate (or your negotiated rate), plus any add-ons (additional modules, extra storage, premium support SLA). For a 20-technician shop on ConnectWise Standard at $99/seat/month, that's $1,980/month or $23,760/year. For HaloPSA Pro at $99/seat, the same math applies. The license cost difference between competing PSAs at the same feature tier is rarely more than $20-30/seat/month.
Indirect PSA costs are where the real variance sits. PSA administrator time: if someone spends 10 hours per month on PSA configuration, reporting, and maintenance at a fully-loaded cost of $75/hour, that's $750/month in indirect labor. Technician inefficiency: if 15 techs lose an average of 20 minutes per day to PSA friction (slow search, extra clicks, workarounds), that's 5 hours per day or ~100 hours per month of lost billable capacity. At $125/hour opportunity cost, that's $12,500/month. Interface-driven inefficiency is the largest hidden PSA cost and the hardest to quantify without measuring it deliberately.
What should a PSA return? The PSA is the system that ensures every hour logged gets billed, every contract gets invoiced correctly, and every client's profitability is visible. A PSA that runs well should contribute to 100% billing capture on time entries, zero invoice errors on recurring agreements, and real-time visibility into which clients and service lines are profitable. If you can't get those three things from your current PSA, you are leaving money on the table regardless of what the platform costs.
The switching economics calculation: (indirect cost reduction per month - migration cost amortized over 24 months) = monthly net benefit. A migration that costs $25,000 in lost productivity and implementation costs amortized over 24 months is $1,042/month. If the new PSA saves $3,000/month in indirect costs (technician efficiency + admin time + reporting labor), the net benefit is $1,958/month starting at month 25. That's a real return worth modeling — but most operators don't do the model before committing to a migration, which is why migrations often feel more expensive than expected.
