How to track ar aging and run collections on Starch
AR aging is the practice of sorting your outstanding invoices by how overdue they are — current, 30 days, 60 days, 90 days, 90-plus — and then doing something about the ones that are slipping. Collections is the follow-through: the emails, calls, and escalations that turn an aging report from a scorecard into cash. Together they answer two questions every operator needs to know: who owes me money, and what am I actually doing about it?
What this workflow looks like in practice varies. A SaaS business is chasing a handful of enterprise invoices and watching DSO as a north-star metric. A services firm is managing dozens of client retainers with inconsistent net terms. A product business is dealing with distributor payment cycles that don't match its own payables. The specifics differ; the core problem is the same.
On Starch, you end up with a live AR aging dashboard that pulls directly from your accounting data — invoices, payment status, and days outstanding — alongside an automated collections workflow that drafts follow-up emails for overdue accounts and surfaces the worst offenders in Slack or your inbox each week. No spreadsheet exports from QuickBooks. No manually checking which clients still owe you for last month. The report updates, the reminders go out, and you see exactly where your receivables stand without having to go looking.
Why it matters
Poor AR management is one of the most common reasons a profitable business runs short on cash. If your DSO creeps from 35 days to 55 days and you don't notice until month-end close, that's three weeks of working capital you've quietly lent to your customers interest-free. Done well, a tight collections workflow shortens payment cycles, reduces write-offs, and means your cash position actually reflects your revenue — not a lagging approximation of it.
Common pitfalls
The most common mistakes: treating AR aging as a reporting exercise rather than a trigger for action — you run the report, feel bad about the 90-day column, and move on. Relying on your bookkeeper's monthly close to find out who's overdue, when the information is available daily. Sending the same generic payment reminder to a $200 invoice and a $20,000 invoice. And conflating accrual revenue with cash — an invoice booked is not cash collected, and dashboards that blur that line give you false confidence on runway.
