Looking for Bulk Custom T-Shirts? Here Are 10 Things You Should Know Before Ordering

Ordering a massive pile of shirts sounds easy until you’re staring at a spreadsheet of sizes and a low-resolution logo.

Whether you are launching a streetwear brand, kitting out a construction crew, or prepping for a massive event, bulk ordering is a different beast than buying a single gift. You want high quality. You want a fair price. You want them delivered yesterday.

At So Boss, we handle bulk custom t-shirts every single day. We know where the traps are hidden. We know how to save you money without sacrificing the "cool" factor.

Here are the 10 things you absolutely must know before you hit that order button.

1. Do you actually know your size distribution?

Guessing is the fastest way to end up with fifty "Small" shirts that nobody can wear.

When you order personalised clothing australia wide, you have to account for the "Bell Curve" of sizing. Generally, Medium and Large are your heavy hitters. XL and 2XL follow closely behind. Small and 3XL+ are usually your outliers.

(Pro tip: If you are ordering for a corporate event, lean slightly larger. Nobody ever complained about a shirt being too comfy, but a shirt that’s too tight stays in the drawer.)

Ask. Survey. Confirm.

If you can't get a headcount, use a standard ratio: 1:2:3:2:1 (S:M:L:XL:2XL). This isn't perfect, but it’s a lot safer than a blind guess.

2. Which printing method fits your deadline?

Not all prints are created equal. The technology we use depends on your design, your fabric, and your timeline.

If you need same day custom t shirts, Direct to Garment (DTG) is your best friend. We use DTG for high-detail, full-colour designs that need to go out the door fast. (We only claim same-day print and dispatch for DTG orders). It’s perfect for cotton-heavy garments like our Premium Cotton Tee.

Need more versatility? Direct to Film (DTF) is available across our full range. It’s durable, vibrant, and works on almost any material. (Note: DTF is not available for same-day dispatch, so plan accordingly).

Screen printing is the old-school king of huge bulk runs, but it takes time to set up screens. If you’re in a rush, look at our digital options.

3. Is your design file "Print Ready" or just "Okay"?

A blurry screenshot from your phone will look like a blurry mess on a shirt.

To get that crisp, professional look, you need high-resolution vector files. We're talking AI, EPS, or high-quality PDF. If you only have a PNG, make sure it has a transparent background and is at least 300 DPI.

Bad files lead to delays. We want to get your order moving. Check your files. Trace your lines. Export with care.

Think. Create. Print.

If you aren't sure, check out our Portfolio to see how sharp a proper file looks on the finished product.

4. Have you considered the fabric weight?

"It's just a t-shirt" is a lie.

Fabric weight is measured in GSM (Grams per Square Metre). A low GSM (130-150) is great for promotional giveaways or hot summer events. A high GSM (180-220+) feels premium, heavy, and durable.

For a classic, high-quality feel, our Vintage Wash Graphic Tee offers that structured look that people actually want to wear on the weekend. Don't buy "disposable" clothes. Buy something that lasts.

5. Are you accounting for the "Hidden" costs?

The price per shirt is only one part of the story.

When comparing quotes for bulk custom t-shirts, look for the extras. Is GST included? What about shipping? Are there "setup fees" for every single colour in your logo?

At So Boss, we keep it simple. We value transparency. We hate surprise bills as much as you do. Always confirm the "landed" price: the total cost to get those boxes to your front door.

6. What is the real turnaround time?

"I need them by Friday" usually means you should have ordered last Monday.

Standard bulk orders take time to process, print, and ship across Australia. While we excel at speed, shipping carriers can be unpredictable.

If you are aiming for a specific slot, remember our 4pm processing window. Orders confirmed after the cutoff move to the next business day.

Plan. Order. Relax.

If you are truly under the pump, head straight to our Custom Tees section and look for the DTG options for the fastest possible turnaround.

7. Should you order a sample first?

If you are ordering 500 shirts, spending a few bucks on a single sample is the smartest insurance policy you can buy.

A sample lets you touch the fabric, check the sizing, and see how your logo interacts with the garment colour. It eliminates "The Oh No Moment" when the big boxes arrive.

(We recommend this especially if you are trying a new style like a Long Sleeve Custom T-Shirt for the first time).

8. Why you should always order 5% more than you need.

The "Buffer" is a lifesaver.

Someone always forgets to put their name on the list. Someone always changes their mind and wants an XL instead of a Large. Or, in rare cases, a shirt might get damaged during a hectic event.

Ordering an extra 5% is cheaper than placing a tiny "top-up" order later. Small runs are always more expensive per unit than bulk runs. Save yourself the stress. Buy the extras now.

9. Is it just shirts, or do you need a full kit?

If you're already doing a bulk run, consider the "Bundle" effect.

Consistency is key for branding. If your team has custom tees, they’ll eventually want custom headwear or hoodies for the cooler months.

Adding some Classic Baseball Caps or a Classic Pullover Hoodie to your order can often streamline your shipping costs and keep your brand look uniform.

10. Who is actually printing your gear?

Are you dealing with a middleman or the actual printer?

Many websites just take your order and outsource it to the cheapest factory they can find. This leads to poor communication and zero quality control.

We are So Boss. We live and breathe apparel printing. When you talk to us, you’re talking to the people making your gear. We care about the stitch, the ink, and the delivery.

Ready. Set. Go.
