Most electrical software is rented by the year: estimating, a material price-update service, takeoff, and accounting all bill again and again. Stinger Pro is a one-time $4,500 license. Put in what you pay now and see the difference over time.
Enter what you pay per year (leave anything at 0 if it doesn’t apply). Not sure of a number? Use the hint under each box as a rough guide.
Stinger Pro is a one-time $4,500 perpetual license (free fixes for the current version; major new versions offered to existing customers at a discount). This calculator treats your entries as recurring annual costs and compares them to that one-time price over the period you choose. It’s an estimate based on what you enter — your real numbers and any negotiated pricing will vary.
A rented stack keeps charging after the software is long paid for. A material price-update subscription alone can run $2,300–$9,000 over five years, on top of the estimating software. Because Stinger Pro loads a free supplier or manufacturer price file, that recurring line can disappear entirely. Want the full breakdown of the market, with sources? Read the 2026 buyer’s guide.
One program, one price — estimating, takeoff, scheduling, job cost, and accounting.
