Introduction to Products: catalog, stock, categories & modifiers
The Products section of the Merchant Hub includes the Product List, Categories, Attributes, Modifiers, Stock Transfers, and Units of Measure. Modifiers is where you create options and add-ons — like toppings or milk choices — and attach them to categories so they appear automatically at the till.
What's in the Products section?
The Products section of the Merchant Hub is where you build and maintain everything in your catalog. It has six areas:
| Area | What it does |
|---|---|
| Product List | Add, edit, and organize your products and their variants. |
| Categories | Group products into categories and subcategories, and attach modifiers to them. |
| Attributes | Create reusable options — like Size or Color — that power product variants. |
| Modifiers | Define options and add-ons (toppings, milk choices, extras) and attach them to categories so they appear at the till. |
| Stock Transfers | Move inventory between Outlets. |
| Units of Measure | Create custom units for selling by weight, volume, or pack size. |
Product List
The Product List shows every item in your catalog. From here you can:
Add a new product and set its name, price, tax group, and inventory.
Add variants (for example, Small, Medium, Large) using attributes.
Assign products to categories.
Adjust stock levels.
See How to add a product and How to set up variants for step-by-step guides.
Categories
Categories group your products so they're easier to find at the till and in reports. You can nest subcategories inside parent categories as deeply as you need.
Categories also control which modifiers a product inherits. Attach a modifier to a parent category and every product in that category — and its subcategories — gets it automatically.
See How to organize products with categories.
Attributes
Attributes are the reusable building blocks for variants — options like Size (Small, Medium, Large) or Color (Red, Blue, Green). Create an attribute once and use it across as many products as you need.
Modifiers
Modifiers let you ask customers a question at the till — "Which dressing?", "Any add-ons?", "How many scoops?" — and charge for the answer automatically.
You define each modifier once (with its choices, pricing, and rules), then attach it to the categories where it applies. Products in those categories inherit the modifier automatically — no per-product setup needed.
Modifier types: Pick One, Pick Many, and Quantity.
Rules per attachment: Set whether a modifier is required, and the minimum and maximum number of selections. The till enforces these rules and tells staff the reason if a line is blocked.
Per-outlet availability: Mark individual choices unavailable at specific Outlets. The Merchant Hub warns you at configuration time if a required modifier has no sellable choices at an Outlet.
Receipts and kitchen tickets: Every selected choice — including $0.00 options — prints by name and amount.
See How to set up product modifiers for a full walkthrough.
Stock Transfers
Move inventory from one Outlet to another with a stock transfer. Choose the source and destination, set quantities, send the transfer, and mark it received at the destination.
See How to transfer stock between outlets.
Units of Measure
Sell by weight, length, volume, or a custom pack size. Create your own units here and assign them to product variants.
