If you've been pressing shirts for more than a few weeks, you already know the feeling. You're mid-run, about to press the last 12 shirts of an order, and you realize you're short on blanks. Or you go to grab a specific transfer design and the stack is empty. Or you sell something online and don't actually have the blank to press it.
These aren't bad-luck situations. They're inventory management problems — and they're completely fixable once you build the right system.
Why Heat Press Inventory Is Different
Most inventory advice is built for retail — count the widgets on the shelf, reorder when you hit a threshold. Heat press inventory is more layered than that. You're managing at least three moving parts at once:
- Blank garments — by style, color, and size
- Transfers — by design, type (DTF, plastisol, sublimation), and quantity
- Finished/pressed goods — what's actually ready to sell or ship
Each of those categories interacts with the others. A blank doesn't become sellable until you pair it with the right transfer and press it. That dependency makes tracking more important, not less.
Step 1 — Separate Your Inventory Into Categories
The first move is to stop treating everything as one big pile. Break your inventory into clear categories and track each one separately.
Blank Garments
Track by style (t-shirt, hoodie, long sleeve), color, and size. A white Gildan 64000 in a medium is a completely different inventory item than a black one in an XL. You need to know exactly how many of each you have — not "a bunch of white shirts."
Transfers
Log each design separately, including the transfer type. A DTF of your logo design and a plastisol of the same design are different items with different storage needs and press settings. Track them that way.
Completed Goods
Once a shirt is pressed, it moves out of blanks and into finished inventory. Keep a separate count of pressed shirts by design, size, and color. This tells you what's ready to sell right now versus what still needs to be pressed.
Step 2 — Set Low Stock Thresholds
Decide in advance at what point each item needs to be reordered. For blanks, that might be when you drop below a dozen of any given size. For transfers, it might be when a design gets below 10 units. Write these numbers down — or better yet, set them in your tracking tool so you get alerted automatically.
The goal is to never be making a reorder decision reactively. By the time you notice you're out, it's already a problem. Low stock thresholds give you lead time to reorder before you run dry.
Step 3 — Update Inventory in Real Time
This is where most pressers fall down. They plan to update their inventory counts at the end of the week, then get busy and skip it, then lose track entirely. The only system that works is one where you update as you go.
When a box of blanks comes in — log it. When you press a run — log it. When you ship an order — log it. It takes 30 seconds and it keeps your numbers accurate. Accurate numbers are the whole point.
Step 4 — Audit Regularly
Even with a good system, physical counts drift from recorded counts over time. Transfers get used for samples. Blanks get set aside for reprints. Do a quick physical audit once a month — walk your stock, count what's actually there, and reconcile against your records. Catching a discrepancy early is a five-minute fix. Catching it six months later is a headache.
The Right Tool Makes All of This Easier
You can manage heat press inventory in a spreadsheet. Plenty of people do. But spreadsheets weren't built for this — they don't alert you when stock gets low, they don't separate blanks from transfers from finished goods cleanly, and they're a pain to update from your phone while you're at the press.
PressTrak was built specifically for heat press inventory. It tracks blanks, transfers, custom items, and completed goods in one place — with low stock alerts, mobile-first design, and no spreadsheet gymnastics required. It's free to start.
