How to Start a Custom T-Shirt Business with Print-on-Demand

Start a t-shirt business today with no upfront costs. No basement full of shirts. No expensive machines.

Print-on-demand does everything for you. You make designs. Customers order. They print and ship each shirt.

Here's how to build a profitable t-shirt business from your laptop.

What is Print-on-Demand?

Print-on-demand companies only print when customers order.

How it works:

You upload designs to their website.
Customer orders a shirt with your design.
Company prints and ships to customer.
You get paid the profit.

Good POD companies:

Printful has high quality.
Gooten has good prices.
Printify has lots of products.
Tspring has built-in store.

Each has different costs and quality levels.

Pick Your Niche

The t-shirt market is huge but busy. Target specific groups, not everyone.

Good niches:

Pet owners work well. Target specific dog breeds.
Jobs like nurses and teachers.
Hobbies like fishing and gaming.
Local pride for your town.
Funny sayings for specific people.
Fitness motivation quotes.

How to research:

• Check Facebook groups for your niche
• See what t-shirts people share
• Look at top sellers on marketplace platforms
• Read customer reviews

Avoid crowded markets unless you have something new.

Make Your Designs

You don't need to be an artist.

Design tools:

Canva has easy templates.
GIMP is a free photo editor.
Procreate is an iPad drawing app.
Photoshop is pro but costs more.

What sells:

Text designs with clever sayings.
Simple graphics.
Old-style art.
Clean minimal designs.
Inside jokes for your niche.

File needs:

Use 300 DPI quality.
Save as PNG format.
Make 4500x5400 pixels.
Works on different shirt colors.

Understand Costs

What POD charges:

Basic t-shirts cost £8-12 to make.
Premium shirts cost £12-18 to make.
Tank tops cost £7-10 to make.
Hoodies cost £15-25 to make.

What to charge:

Basic tees: £18-25. You make £6-13 profit.
Premium tees: £22-30. You make £7-15 profit.
Hoodies: £35-45. You make £15-25 profit.

Profit margins: 30-50% is normal

Check what others charge. Price fairly but don't go too low.

Set Up Your Shop

Where to sell:

Marketplace platforms: Built-in traffic but high fees. You don't own the customer relationship. They can change the rules any time.

Your own website: Best long-term plan. You control everything. You own every customer email and build real brand value.

Most website platforms charge £25-80/month before you sell a single t-shirt. With Astrocart, you get a free website until £2,500 per month in sales. POD integrations work out of the box. Email marketing, analytics, and AI tools all built in. No monthly fees, no app maze.

Take Good Photos

POD companies give you product mockups. But custom photos sell better.

Photo tips:

Show designs on real models.
Take flat shots of the shirt.
Show different settings.
Use same lighting style.

Free mockup sites:

Canva has t-shirt mockups.
Printful gives free mockups.
PlaceIt has subscription service.

Good mockups make designs look pro.

Get Found Online

T-shirt sales depend on being found in search.

Find keywords:

Use free Google tools.
Look for long phrases people search.
Study successful listings.

Write good titles:

Put main keyword first.
Say what shirt style it is.

Product text:
