I wrote this one because of a conversation I keep having. A shop owner tells me business is great, the presses are running, orders are steady. Then we pull one job apart and find out they're losing money on it. They just couldn't see it from where they were standing.
That's the whole problem with a profit leak. It doesn't announce itself. It drips under the floorboards while you're busy being busy, and by the time you notice the water damage, it's expensive.
On a DTF or DTG order, that math gets brutal fast. A run of 288 screenprinted shirts can eat one bad print across the other 287. A unit-of-one order can't. When it goes wrong, you eat the whole thing at full margin. So every leak I dig into here hits harder in a digital shop for the same reason: the volume isn't there to absorb it.

- Why your single biggest profit leak lives in the front office, not on the production floor
- The costs that never make it into your price (and how to find them with one real order and a spreadsheet)
- Program and merch work priced once, wrong all year, and locked in for the life of the SLA
- The "good customer" who keeps you humming at flat margin and always pays 45 days late
- Cost of Poor Quality (COPQ), and why almost no shop I talk to is tracking reprints
- The $5 wiper blade you skipped that turns into a $1,000 printhead

One thing to do before you read it: pull one real order at random. Load every cost tied to that job into a spreadsheet, including the ones you never think about. Labor, materials, and freight are easy. Insurance, marketing, credit card fees, cell phones, and the other P&L line items are the ones that hide. Seeing where your money actually goes is exactly the kind of clarity 2026 Thinking is built around, and it's a free download. Then compare what you charged against what it actually cost you to run.
Can you spot the leak?
