Agencies live with a quiet math problem. You bill net-30. Your clients pay net-90. In between, you're the one covering payroll, contractor invoices, and software — financing your client's cash flow with your own.
It isn't usually malice. It's process. Here's why the gap opens, and how to close it without turning into the bad guy.
Where the 90 days actually goes
A "net-90" client rarely decides to pay you in 90 days. The delay is assembled out of small, boring steps:
- The invoice sits unopened for a week because it went to a shared inbox no one owns.
- It waits for approval from someone who's traveling, or who needs a project code you didn't put on the invoice.
- It enters a payment run that only happens twice a month.
- It slips a cycle because it missed the cutoff by two days.
Stack those up and 30-day terms quietly become 90. None of the steps are hostile. All of them are fixable.
Make the invoice easy to say yes to
Most of the delay happens before a human ever decides not to pay you. So remove the friction:
- Address it to a person, not a company. "Accounts payable" is a black hole. A name is accountable.
- Put everything the approver needs on the invoice — PO number, project code, the contract reference. Every missing field is a round-trip that costs you a week.
- Send it the day the work is accepted, not at month-end. An invoice that arrives while the work is fresh gets approved faster.
Then follow up like a professional, on a schedule
The single biggest lever is consistent, calm follow-up. An invoice that gets one polite nudge at day 3, another at day 14, and a short check-in at day 30 gets paid far sooner than one that's left alone until it's a problem.
The catch: doing that by hand, across every client, every invoice, is a part-time job nobody on your team wants. So it doesn't happen — and the 90 days win.
Shorten the gap, keep the client
You don't need a lawyer or a hard conversation to pull net-90 back toward net-30. You need the boring parts to happen every time: a clean invoice, sent early, followed up on a schedule, in your own voice.
That's exactly the work FetchDue takes off your plate. It sends from your own mailbox, follows up on the right day, reads the reply, and drafts your answer — so the gap closes and the relationship stays yours.
