Reading the ageing
Money in the 0–30 column is normal credit. 31–60 needs a reminder; 61–90 a phone call; over 90 days a hard look at whether to keep supplying. Watch the parties whose 90+ column keeps growing.
Cashflow OS builds this from your TallyPrime bills for every party, every day — with their statement and a WhatsApp reminder a tap away. Nothing you paste here leaves your browser.
Questions people ask
What is receivables ageing?
A list of what each customer owes, split by how old the unpaid bills are — usually 0–30, 31–60, 61–90 and over 90 days. It shows where collections are stuck.
Should ageing count from the bill date or the due date?
Both are used. This tool counts from the bill date, or from the due date when you enter credit days. Pick one and use it every month.
Can I get this from Tally automatically?
Yes. Cashflow OS reads your bill-wise outstanding from TallyPrime and shows ageing for every party on the phone and web, updated with each sync.
