Setting up your product and services catalog

Products & Services is a shared catalog for everything you sell. Give an entry a short code, and typing that code into an invoice or quotation line item fills in the description and price for you — no re-typing the same thing every time.

Products vs. Services

Each catalog entry is either a Product — a physical item, eligible for stock tracking — or a Service, billed by description only, with no quantity-on-hand to track.

Codes and barcodes

Both Product Code and Barcode must be unique across the catalog — reusing one throws an error at save, so there's never ambiguity about which item a code refers to.

HSN/SAC codes (or HS codes — your call)

Once tax is turned on in Settings, each entry can also have a classification code — "HSN/SAC" by default, since that's the Indian GST term, but the label itself is editable under Settings → Tax, so it can read "HS Code" or anything else that matches how your country classifies goods. It's optional, and set once here rather than re-typed on every invoice line.

Deleting vs. archiving

A product or service can't be deleted while it's used on any invoice or quotation line, for the same reason customers with invoice history can't be deleted — that history has to stay. For something discontinued, see How to archive a discontinued product instead.

If you sell physical items and want to track how many you have on hand, see How stock tracking works in WatCoreLite.

Bulk-updating prices or adding items with AI

Got a supplier's price list to work through? 🤖 AI Import/Export, next to "+ New item", uses the same AI Fill mechanic to update several prices — or add several new catalog entries — at once, without touching each one by hand. See AI Fill: turn an order or bill into line items automatically for the full mechanic.
