Using your accounting data, Helm calculates how quickly customers pay your company after you invoice them. This is called ADR, or Average Days Receivable.
ADR is calculated individually for each customer your company has. While it's a bit more work, this helps us provide highly accurate estimates of the timing of your receivables.
You invoice Customer A. Customer A then usually takes 47 days to remit payment to your company. ADR = 47.
You invoice Customer B. Customer B then usually pays upon receipt of their invoice. ADR = 0.
(as a side... you should probably do more business with Customer B)
