DIGITAL TOOLS Decision tools you buy once and run on your own machine.
These are private, offline, browser-based tools, not SaaS. Open the file, enter your numbers, get a
decision. No sign-up, no subscription, and no data leaves your computer unless you export it
yourself. Below are three decision simulators built to the same standard, plus three shorter guides
on the same operating problems.
Want to see how they work before paying for one? Each has a
free calculator that runs the same engine in your browser, with no
signup and no email capture.
FREE, NO SIGNUP Six calculators you can use right now without paying anything.
No email required, nothing uploaded. Four are single-unit versions of the paid simulators;
two answer the marketing questions every local operator eventually asks. If the free
version answers your question, keep it.
Missed-Call Revenue Calculator
Free
Call volume, your miss rate (or a sourced industry default), close rate and job value
in; monthly and annual revenue at risk, value per missed call, and an honest break-even
against fixing it out. It will tell you when the fix does NOT pay.
Open the calculator Span of Control Calculator
Free
Headcount, loaded cost and a target span in; the management structure that span
implies, the annual run-rate difference, and a manager-capacity time test out.
One org-wide unit.
Open the calculator Erlang C Staffing Calculator
Free
Calls, handle time and your service standard in; productive agents, the roster you
have to schedule after shrinkage, achieved service level and occupancy out. One
interval.
Open the calculator Warehouse Shift Capacity Calculator
Free
Backlog, forecast, rate and roster in; the capacity that shift really produces after
shrinkage and attendance, the backlog it closes with, and the headcount needed to hit
your target out. One function, one shift.
Open the calculator Local Ads ROI Calculator
Free
Monthly spend, CPC, conversion rate, close rate, job value and margin in; the whole
chain out: leads, cost per customer, ROAS, actual profit, and the maximum CPC your
economics can afford. It will tell you when the account loses money per click.
Open the calculator LTV vs CAC Calculator
Free
Average ticket, purchase frequency, margin, retention and acquisition cost in;
margin-based lifetime value, LTV:CAC ratio, payback months, and the most you can
afford to pay for a customer out. Refuses to compute the flattering revenue version.
