Ask an agency owner what's eating their margin and they'll usually point at the obvious things: scope creep, under-quoting, the cost of tools. Rarely does anyone say "approvals". Yet the gap between finishing work and getting it signed off is one of the most expensive things in a agency, precisely because it never appears on an invoice. It's a cost that hides. Let's find it.
The delay never stays put
A single late approval feels harmless. A day here, two days there. But agency work is a pipeline, and a stall at one stage backs up everything behind it. The designer who's blocked waiting on sign-off can't cleanly start the next job. The project manager reshuffles the schedule. A deadline three projects away quietly slips. One slow yes doesn't cost you one delay. It costs you a cascade.
Cashflow, not just calendar
Finished-but-unapproved work is revenue you've earned but can't bill. Every day it waits is a day your money sits in someone else's inbox. For a small studio, a few large deliverables stuck in review at month-end can be the difference between comfortable cashflow and chasing it.
The capacity you can't see
The most expensive cost is the one you never notice: capacity you can't reinvest. When your team's output is trapped in approval limbo, you can't roll that capacity into the next piece of work. You feel busy, because everyone's "waiting on the client", but throughput drops. You're paying for a full team and shipping like a smaller one.
Morale leaks, too
Chasing approvals is nobody's favourite job. The follow-up emails, the "sorry to bug you again", the awkwardness of nagging a client you like: it's a low-grade tax on your team's energy and on your client relationships. Do it often enough and it sours both.
Putting a number on it
Vague costs are easy to ignore, so make it concrete. Take your monthly project volume, your average approval wait, and your day rate, and multiply them out across a year. Most people are surprised how large it gets. We built a small tool to do exactly this:

The fix is process, not pressure
The good news is that this is one of the cheapest problems in an agency to fix, because it's mostly friction. Lower-friction approvals, clearer single decisions, automated follow-ups, and visible status turn a five-day wait into a one-day one. For the specific habits, see how to get clients to approve designs faster (without nagging).
The cost of slow sign-off is real, it compounds, and it hides. Drag it into the light and it's surprisingly easy to shrink.
