Built around how t-shirt sellers actually work

  1. Screen fees need a run to spread across

    A $90 screen setup across 50 shirts is $1.80 each; across 12 shirts it's $7.50. Costing the run, not just the shirt, tells you the minimum print quantity that keeps a design profitable.

  2. The bestseller is always out of large

    Sizes sell unevenly and larges lead. From the Team plan, a "keep at least" level on each size means the restock happens before your top design goes half-sellable.

  3. Misprints eat quiet margin

    A 4% misprint rate on a 50-run is two shirts you paid for and can't sell full price. Build the loss into the recipe and let seconds become a planned discount rack.

  4. Markets and online, one pile of shirts

    The tote you take to a market holds the same inventory your site sells. From the Maker plan, one count that every recorded sale comes off keeps Saturday's booth from overselling Sunday's web orders.

Worked example

Mountain Graphic Tee, costed line by line

This is the math Keepsel does for every product you make: every line from its recipe, updated whenever a material's price changes.

The same design on a 12-shirt run would cost $10.85 a shirt: run size is the hidden pricing lever.

Track everything that goes into a t-shirt

From raw materials to the finished piece, Keepsel keeps t-shirt sellers on top of:

  • blank tees and totes
  • ink and heat transfers
  • thread
  • hang tags
  • poly mailers

A day in Keepsel, for t-shirt sellers

Step 1

Book blanks in by size

A case of blanks goes in as counted stock per size and color, at the price this order actually cost.

Step 2

Cost each design per run size

Blank + print-per-shirt (screens spread across the run) + tag + bag = a real unit cost you can price from.

Step 3

Print and log the run

From the Maker plan, a work order for a 50-shirt run deducts blanks and ink and adds sellable shirts by size (work orders up to 10 a month on Maker as a trial and 100 on Team, unlimited on Business and Enterprise).

Step 4

Restock the winners

With your sales recorded, from the Maker plan you can ask Suli which tee and size earn the next print run, and how big it should be.

Questions t-shirt sellers ask

How much does it cost to make a graphic t-shirt?

A mid-weight blank runs $2.50–$4, printing $1.50–$3 per shirt at reasonable run sizes, plus tags and packaging, so $5–$7 all-in is typical. The number swings hardest with run size, which is why costing the run matters more than costing the shirt.

What's the right print run size for a new design?

Big enough to spread setup costs, small enough not to strand cash in slow stock. Break-even math per run size shows the floor; past drops' sell-through shows the ceiling. Start closer to the floor and let a restock prove demand.

How should I price t-shirts at markets versus online?

Same shirt, same floor: your all-in cost. Markets add booth fees, online adds platform fees and shipping; count both and you may find your "cheaper" channel isn't. From the Maker plan, Keepsel puts each sales channel's fees in a shirt's margin. Many sellers hold one price and let the channel fees decide where to push.

How do I track t-shirt inventory by size?

From the Maker plan, sizes are variations under each design, so stock and cost resolve per size. You'll see larges selling through and smalls stacking up, and buy the next case accordingly.

What do I do with misprints and seconds?

Count them. A seconds item at a discount turns print errors into revenue and keeps your A-stock counts truthful, and the misprint rate itself tells you when a supplier or screen needs attention.

How to Price T-Shirts (Run Size Changes Everything)

The same design costs $5.15 a shirt on a 50-run and $10.85 on a 12-run. Price the run, not just the shirt.

What's the Right Batch Size for Your Products?

Batch too small and you're always setting up; batch too big and you're sitting on stock. Here's how to find the size that's actually efficient for you.

Break-Even: How Many Do You Need to Sell?

Before a product, a batch, or a market booth pays off, it has to cover its costs. Break-even is the number that tells you exactly when that happens.

How to Forecast Demand for a Brand-New Product

Forecasting from sales history is easy. Forecasting a product with no history is the real challenge. Here's how to make a smart first guess, and de-risk it.
