The problem
Your aging report starts after the due date.
When every overdue invoice looks equally urgent, teams chase the loudest account or the oldest balance. PaidWhen adds a forward-looking view, so your weekly review starts with the invoices that combine meaningful value with a higher chance of delay.
It does not replace your accounting system. It gives your team a clearer order of work.
How it works
Two CSV files in. One prioritized list out.
Start with the sample data, then use exports from your own accounting system when you are ready.
Check whether the pattern is useful
PaidWhen learns from older invoices and checks its estimates against newer ones. If the result is weak, it tells you.
Work from the top of the list
Review invoices ranked by estimated cash at risk, inspect the reason, and choose the right follow-up for the customer.

What to know before you use it.
Who is PaidWhen for?
PaidWhen is for B2B finance, accounts-receivable, and bookkeeping teams that have enough invoice history to make a weekly collections review more focused.
What files do I need?
You need one CSV of closed invoices and one CSV of open invoices. The required fields are invoice ID, account key, invoice date, due date, and amount. Closed invoices also need a payment date.
How much history should I have?
Sixty or more clean closed invoices is a practical starting point, with both late and on-time payments represented. More history usually produces a more useful test. PaidWhen warns you when the data is too thin.
What does ‘cash at risk’ mean?
It is the open invoice amount multiplied by the estimated chance of late payment. It helps a team balance probability with financial impact when deciding what to review first.
Do my invoice files leave my browser?
No. File reading, validation, scoring, and exports happen in your browser tab. If you request an optional action brief, only a small summary of dates, amounts, and risk values is sent—never your CSV or account and invoice IDs.
Does PaidWhen contact customers?
No. PaidWhen suggests a next step, but a person reviews the customer context and decides whether any message should be sent.
