Inside a Shopify Bulk T-Shirt Order Calculator: Every Size and Color in One Order

A team shirt order rarely comes in one size. The T-Shirt Bulk Order demo takes the whole order on one product page: colors down the side, sizes across the top, and a count in each box. It runs on Appify Custom Product Options.

Each shirt costs the blank plus a charge for every print location. The total of the grid sets the quantity break. With prices in dollars, 25 shirts in two colors, printed front and back, come to 1,552.27 after a 10% break.

What does the T-Shirt Bulk Order calculator do?

The customer picks a color in the first row and types how many of each size they need, XS to XL. Picking a color opens a fresh row for the next one. Then they choose the print locations, and Design Shirt opens the design editor.

Every shirt in the grid gets the same print locations.

Why is a bulk shirt order hard to sell online, and how is it handled?

• One order holds many sizes and colors. The grid takes every color and size count in one form, with one Add to cart.
• Prints are priced per shirt. Each location adds its charge to every shirt, so a front and back print is paid on all 25 shirts, not once.
• The break counts the whole order. 15 Gold and 10 Blue shirts reach the 25-shirt break together. No single size has to reach it alone.
• The break covers the prints too. The 10% comes off the full shirt price, prints included.
• The order has to stay readable. The cart line lists every color and size with its count.
• Team orders change before checkout. Someone always needs one more Medium. The customer can reopen the grid from the cart instead of starting over.
• The artwork comes with it. Most options apps have no design canvas at all. Here, Design Shirt opens the Product Designer on the same page.

How is one price worked out?

Take a team order of 15 Gold shirts (3 S, 5 M, 5 L, 2 XL) and 10 Blue shirts (2 S, 4 M, 3 L, 1 XL), printed on the front and the back.

The price summary under the calculator shows the same total, and 62.09 per shirt with the full 68.99 struck through.

Leave the last Blue XL out and the order is 24 shirts. That sits on the 10-shirt break, 5% off, for 1,572.97 in all. The 25th shirt moves the whole order up a break.

How does the quantity grid work?

Colors down the side, sizes across the top

Each row is one color and each box is one size of it. The demo offers Gold, Pink, Sapphire, Blue and Red, in XS, S, M, L and XL. A color already in the grid drops out of the next row's list, so the same color can't end up in two rows.

Blank boxes count as zero

The customer fills only the sizes they need. In the example, nobody wanted XS, so those boxes stay empty.

The grid is the quantity

There is no separate quantity box. The summary reads the total of every box, here x 25, and prices the order from it.

The designer sits on the same page

Design Shirt opens the Product Designer. The shirt has its own sides and print areas for each location, from the front and back to the shoulders and sides. The customer designs once for the whole order.

The grid and the print locations sit in the designer's right panel, with the order total under them. The customer can change a count or a location without leaving the design.

What are the pricing decisions behind it?

The shirt's price is the starting point

One shirt costs its Shopify price plus the print location charges: 25.00 each for the front and back, 12.50 for a shoulder and 18.00 for a side. The total price formula prices per unit, so the grid's total multiplies that one shirt.

One ladder, counted on the whole grid

The quantity discount rules apply per cart line, and the whole grid arrives as one line. So the total of every color and size picks the break, not any one size.

The summary shows the price per shirt

The price summary shows the shirt, the locations, the quantity, the total and the unit price. Once a break applies, the customer sees the full price per shirt struck through beside the new one.

What arrives with the order?

The whole order lands in the cart as one line. It lists the grid total, every color and size with its count, the print locations and the break.

Customers can edit the order in the cart. A coach who forgot two Medium shirts taps Edit options, and the grid reopens with every count filled in.

The same line appears in the Orders tab with its options. For repeat orders, signed-in customers can use Appify Reorder, which brings back the custom options that Shopify's Buy again button drops.

How can you make it yours?

• Add a setup fee. A fixed fee sits on top of the shirts and is never discounted, so a screen setup charge stays whole at any quantity, next to the rest of your custom apparel pricing.
• Switch the ladder by choice. Conditional tables in the quantity discount rules pick a different set of breaks based on what the customer chose on the page.
• Quote a set price per shirt. Swap percent off for target unit price tiers, so 50 shirts cost an exact amount each.

How do you get this calculator?

Start with the grid. Add a Quantity grid option and point it at the product's Shopify options, with Color as the rows and Size as the columns. Then describe the pricing to Chat with AI and check what it builds. A starting prompt:

This product is sold in bulk through the quantity grid, so price it per shirt. Each shirt is its Shopify price plus the print locations picked. Add percent-off quantity discounts on the cart line: 2% at 5 shirts, 5% at 10, 10% at 25, 15% at 50, 20% at 100, 25% at 250, 35% at 500, 45% at 1000 and 50% at 5000.

The print locations and the designer follow the same setup as a single shirt, where customers design the front and back in one session.
