Why Your Print on Demand Shop Isn’t Profitable: 7 Costs You’re Not Counting

The pattern is specific and very common. Orders are arriving. The dashboard shows revenue climbing. And the money in the account is roughly where it was three months ago.

The reason is almost never that POD “doesn’t work”. It is that the costs of a POD sale arrive through five different channels on five different days — the supplier invoice, the marketplace payout deduction, the ad platform’s card charge, the monthly subscriptions, and the tax bill that has not arrived yet — so none of them ever appears next to the sale that caused it.

Full walkthrough of the template used in this guide.

Here are the seven, priced on the same $24.99 shirt throughout. All figures are labelled assumptions; substitute your own.

1. Supplier shipping — $4.75

The base cost is on the product page in big type. The shipping charge is a separate line on your invoice, and if you offered free shipping to the buyer — which most marketplaces effectively require to compete — it is entirely yours.

On this shirt it is $4.75 against a $9.50 base cost. Half again on top of the number you have been using to price. It is the single most commonly missed line in POD maths, and it is not small.

2. The flat fees — $0.45

Payment processing is not just a percentage; it is a percentage plus a flat fee — $0.25 in these examples. Add the $0.20 listing fee and you have $0.45 per order that does not care what you charge.

On a $24.99 shirt that is 1.8%, which is a rounding error. On a $9.99 sticker it is 4.5%, which is often most of the margin. This is why a catalogue of cheap add-on products frequently makes less money than a smaller catalogue of garments, despite selling more units.

3. Listing renewals on designs that never sell — quietly ongoing

A listing renews roughly every four months whether it has sold or not. Fifty published designs, of which forty have never sold, is $24 a year for shelf space nobody is looking at.

The money is trivial. The signal is not: forty dead listings means your attention, your ad testing and your design time are spread across a catalogue where 80% of it has proven it does not sell. The cost of that is much larger than $24.

4. Advertising commissions on sales you didn’t ask for — $3.75 when it lands

If your marketplace runs external ads on your behalf and takes a commission on the resulting orders, that commission applies whether or not you opted in — above a revenue threshold, participation is typically mandatory.

At 15% on this shirt that is $3.75, taking a $7.92 profit down to $4.17. Perfectly survivable. But a seller who priced for a 15% margin is at roughly break-even on those orders and does not know it, because those orders do not look different in the sales feed.

5. Blended ad spend, not attributed ad spend — $1.20 an order

This one is subtle and it is the one that hides the largest sums.

You spend $200 on ads. The platform reports $650 of attributed revenue. ROAS 3.25 — the campaign looks fine, so you leave it on.

But your shop did 160 orders that month, and only 40 were attributed to ads. The other 120 arrived organically. Divide total spend by total orders — $200 ÷ 160 = $1.25 an order — and that is the number that actually left your account per sale.

Attributed cost tells you whether the campaign works. Blended cost tells you whether the business works. Sellers who only track the first can run a permanently “profitable” ad account inside an unprofitable shop.

There is a second version of this trap: a ROAS number means nothing without your margin next to it. On a 31.7% contribution margin, a campaign needs roughly 3.2× ROAS just to break even. A 2.4× ROAS campaign, which looks respectable in any dashboard, is losing money on every order.

6. Refunds and reprints — $14.25 each

This is the one sellers underestimate by the widest margin.

A refunded POD order is not a sale returning to zero. The item was already produced and shipped, the print provider charged you, and they will not reverse it. You are $14.25 out of pocket on a refund that also returns the buyer’s $24.99.

At $7.92 of profit per clean sale, one refund costs you almost two good sales. A 2% refund rate is therefore closer to a 4% cut in profitable volume. Add the reprints for misprints and lost packages — a real cost of doing business at scale — and the “no inventory risk” story becomes a little more complicated than the pitch.

7. Tools, subscriptions and the tax that was never yours — $45 and 25%

Design software, mockup generators, a supplier plan, a scheduling tool. Say $45 a month. It feels separate from the product, so it never appears in any margin calculation — but it comes out of exactly the same profit.

And then tax. POD income arrives in small amounts that feel spendable, and a quarter of it was never yours. Reserving 25% of net profit — a common starting point for a US self-employed seller, though your own rate depends on total income, state and filing status — is the difference between a good year and a bad April.

What the seven add up to

Sixty orders of that shirt in a month:

The base-cost-versus-retail version of that month was $929.40. The real version is $268.65 — 29% of what the simple sum promised.

That is not a failing shop. It is a normal one. The failure mode is not the margin; it is running the shop on the $929 figure — discounting into it, bidding against it, and never raising prices because the margin appears generous.

The fix is one row, not seven habits

None of these costs requires discipline to control. They require being visible on the same row as the order that caused them — landed cost, platform fees, ad cost, and a refund flag that removes the sale from profit while keeping the cost.

Then two roll-ups make the decisions for you: a net profit ranking across the catalogue, which surfaces the designs quietly losing money that a units-sold ranking would never show you, and a monthly P&L that puts fees, ads and tools where you cannot avoid seeing them.

If the answer is that your prices are too low, the pricing formula works backwards from the margin you want. And if it is your landed cost that is the problem, the supplier comparison is where to start.
