Field notes
The tool models software economics across several units: total monthly cost, first-year cost, cost per employee, and cost per client. Its comparison is not limited to a single cheapest bundle; the homepage describes both a lowest-cost combination and a fewest-products combination, alongside capability changes and specialist upgrades. Calculations reportedly stay in the browser, while shareable settings are encoded after the URL’s # fragment rather than sent to the server.
