**In short:** a build-your-own bundle splits a set into slots, such as one top, one bottom and one belt, each filled from its own products. Shoppers fill every slot and get the set at a bundle price. In WooCommerce, [Nanflows Bundles Pro](https://nanflows.com/products/nanflows-bundle) does it with up to 10 slots. Use it when a set has a structure; use mix and match when any N items will do.

Mix and match works when everything comes from one pile. But an outfit isn’t “any three items”; it’s a top, a bottom and something to finish it. That structure is what a build-your-own bundle adds.

Each part of the bundle is a **slot**, with its own products. The shopper fills every slot, and the result is a complete set they chose themselves.

*Build your own: one choice per slot, and the set’s price at the bottom. Sample store.*

This post shows how to build one with [Nanflows Bundles Pro](https://nanflows.com/blog/nanflows-bundles-free-vs-pro).

## Where slots make sense

- **Clothing:** Top: choose 1 · Bottom: choose 1 · Accessory: choose 1.
- **Skincare:** Cleanser · Serum · Moisturiser.
- **Food and hampers:** Something sweet · Something savoury · A drink.
- **Tech:** Device · Case · Charger.
- **Stationery:** Notebook · Pen · Ink.

If you can name the parts, slots fit.

## Setting it up

1. **Bundles → Create Bundle → Build Your Own.**
2. **Name the slots first.** Each slot has a name and how many items to choose from it. You can have up to 10.
3. **Add the products, and put each one in a slot.** Every product belongs to exactly one slot.
4. **Most of the same product:** 1 by default, so nobody takes the same shirt twice.
5. **Set the price:** a fixed price, a percentage off, an amount off, or no discount.
6. Pick the pages and publish.

The editor checks the shape before it lets you publish. If a slot has no products, or a product isn’t in a slot, it says so: “Every slot needs products to choose from.”

## Designing slots people actually finish

A build-your-own bundle only earns money when it’s finished. A few things help:

**Lead with the main item.** People choose the shirt, then match the trousers to it. Put the slot that drives the decision first.

**Three or four slots.** Ten is possible; it’s rarely a good idea. Every slot is another decision.

**Name slots as the shopper thinks of them.** “Top” beats “Upper garments”.

**Keep choices in a slot manageable.** Six good options beat thirty.

**Make every slot sellable.** If a slot’s products sell out, nobody can finish the bundle. Check stock on the smallest slot first.

## Pricing

- **A fixed price** is clearest when the products in each slot cost about the same: “Any shirt, trousers and belt for $99.”
- **A percentage off** is safer when prices within a slot vary a lot: “20% off when you build your look.”

## Gifts work differently

If the bundle is a present, a gift box is usually better: one pool, an exact number of items, and optional gift wrap and a message for whoever packs it.

## In the cart and the order

The bundle goes to the cart as one item, with the shopper’s picks listed under it. In the order, each product shows a visible “Part of bundle” line, so whoever packs it knows what goes together. Stock comes off each product separately.

## FAQ

### Can a slot allow more than one pick?

Yes. Set “Items to choose” for that slot, for example Accessories: choose 2.

### Can the same product be in two slots?

No, each product belongs to one slot. That keeps the choices clear.

### Is this in the free plugin?

No, Build Your Own is a Pro bundle type. For a simpler choose-anything bundle, see [mix and match](https://nanflows.com/blog/woocommerce-mix-and-match-products).
