Agency invoice guides

Honest, practical writing on chasing overdue invoices, comparing AR software, and getting agency clients to pay on time.

These agency invoice guides are written for agency owners, studio founders, and the finance person who ends up doing the chasing. Whether you’re comparing accounts-receivable software, working out what to write at 30 days overdue, or trying to hold a client to the date they promised, everything here is specific and honest about what tools can and can’t do — including ours.

Frequently asked questions

How do I chase an overdue invoice professionally?+

Start with a courtesy heads-up before the due date, a friendly reminder a few days after it passes, a firmer follow-up at 7 to 14 days, and a formal notice around 30 days. Keep every message specific — invoice number, exact amount, days overdue — and let the tone escalate with the delay rather than with your frustration.

What should an agency look for in invoice-chasing software?+

Three things beyond the reminder schedule: whether it connects to the books you already keep, whether you approve messages before they send, and what happens when a client replies — some tools keep sending on a fixed schedule, others detect the reply and simply stop. Also check whether the pricing takes a percentage of the invoices you collect.

How many reminders should I send before escalating?+

Three to four reminders over 45 to 60 days is a reasonable standard, each slightly more formal than the last. After that, a formal letter before action is the appropriate next step, and small claims court after that for most small business debts.

What does DSO mean?+

Days sales outstanding: the average number of days between issuing an invoice and being paid. It is the standard measure of how long your cash sits with clients, and the number most finance conversations about late payment start from.
