Choose stock tracking when you set up a product. You can change the method while the product is a draft. After publishing, the method is locked and quantities are changed from Inventory.
1. Open the inventory section
In the new product form, go to Step 2, Product Type, Inventory & Unit.
Step 2 of the product form, Product Type, Inventory & Unit. The line under the heading repeats your current choice back in one sentence.
2. Choose how the product is sold
Under What kind of product is this?, pick Standard Product for goods sold by the piece, such as clothing, or Weight / Volume-based for goods such as rice and oils. The stock methods that fit appear below.
Two cards: Standard Product for separate items, and Weight / Volume-based for goods poured or weighed out of one container.
3. Choose a stock method
Review the cards under Inventory mode. Press the information button beside it to open How inventory modes work, with examples to help you decide.
Your choice also sets Step 3 for you: No tracking and Track Single Product make a single product, while Per-variant stock and Share Pool Stock turn on Has variants and open the options builder.
Once the kind is picked, Inventory mode appears: four cards for a standard product, and an information button beside the heading that compares the two variant methods.
4. No tracking
Select No tracking when you do not need to keep a count, such as for some made to order products. No unit or quantity is asked. Sales never stop because a count runs out, so switch the product off when you cannot supply it.
No tracking counts nothing at all: the product is always available, never runs out, and never appears on your Inventory page.
5. Single stock
Select Track Single Product for one count without sizes or colours. Choose the Unit of measurement and enter the available Stock Quantity. Step 3 selects Single Product, and you set one price.
Track Single Product keeps one number for the whole product: pick the unit from the row of chips, then fill Stock Quantity.
6. Variant stock
For products with variants, choose the method that matches your stock:
Per-variant stock: no quantity box in Step 2. Build your options in Step 3, then enter a separate Stock for each size or colour in the variants table. This option is not offered for weight or volume products.
Share Pool Stock: enter the total in Shared Pool Total, then build your options in Step 3. In the variants table, set how much each variant takes from the pool, such as coffee bags of different sizes packed from one stock.
On a new product, Opening stock goes to picks the branch or warehouse where the starting quantity is placed.
Per-variant stock gives every size and colour its own number. Share Pool Stock, beside it, keeps one total that every variant draws from.
7. Review before publishing
Check the stock method, unit and quantities before publishing. If you have not finished, press Save Draft to continue later.
After publishing, the form shows Inventory settings locked after creation. To record new stock or correct a quantity, use the Adjust stock link in the form, or open Inventory and press Adjust stock on the product's line.
Reopened after saving: Step 2 carries the notice that inventory settings are locked after creation, and the fields under it are greyed out.
Result
The product is saved with the stock method you chose. After publishing, the form shows Inventory settings locked after creation and you change quantities with Adjust stock.
