FAQ
About these estimates
How the math works, what happens to your inputs, and what we won’t promise.
How are these numbers calculated?
Transparently. Cash tied up = your monthly invoiced amount × the share that runs late × how many months late they typically run. It is an estimate built only from your inputs — actual results depend on your customers and follow-up.
Is my data stored anywhere?
No. The calculator runs entirely in your browser. Nothing you type is transmitted, stored or attached to you.
Will JMJ recover this amount for me?
No one can promise recovery numbers, and we don’t. What JMJ does is run consistent, professional, escalating follow-up on every unpaid invoice — the mechanism that moves payment behavior. The estimate shows you the size of the problem; the cadence is how you attack it.
What if I want a real analysis instead of an estimate?
JMJ Billings works from your actual open invoices — connected from QuickBooks or imported by CSV — so you see your real outstanding and overdue picture, not a model. The estimate here is deliberately aggregate-only.
