Updating stock levels

Stock levels in Vendure tell customers how many of each product are available to buy. For most Flowtech customers, stock is kept in sync automatically from your back-office system (for example, Boomi or an ERP integration). This page covers what to do when you need to adjust stock manually.

Before you change anything

Manual stock changes can be overwritten by the next automatic sync. If your shop syncs stock every 15 minutes from an ERP, any change you make in Vendure will only stick until the next sync — then the ERP value wins.

Before you make a manual change, ask:

1. Is this the right place to change it? If the ERP drives stock, update the ERP. The change will flow through to Vendure automatically.
2. Is there a temporary reason to override? A stock count correction in Vendure is fine if the ERP is also being corrected at the same time. Otherwise, expect the change to be reverted.
3. Is the product a multi-variant product? (e.g. "T-shirt" with Small/Medium/Large). Stock is set per-variant, not for the parent product.

If you're not sure, check with your operations team first.

Finding a product

1. In the sidebar, click Catalog → Products.
2. Use the search bar or filter by collection (category) to find the product.
3. Click the product to open it.

Setting stock for a single-variant product

Some products have only one variant (no size or colour options). For these:

1. Open the product.
2. Click the Variants tab.
3. You'll see a single row representing the product.
4. Click the row to open the variant.
5. Scroll to the Stock section.
6. Update the Stock on hand value.
7. Click Save.

Setting stock for a multi-variant product

For products with several variants (size, colour, fitting type, etc.):

1. Open the product.
2. Click the Variants tab.
3. Each variant appears as its own row. Click the specific variant whose stock you want to change.
4. Update the Stock on hand value in the variant page.
5. Click Save.

Repeat for each variant you need to change.

Understanding the stock fields

You'll see a few related fields:

• Stock on hand — how many units you physically have.
• Stock allocated — how many of those are already reserved against orders that haven't shipped yet.
• Out-of-stock threshold — the level below which the product is shown as out of stock to customers. Usually 0, but can be set higher if you want to keep a safety buffer.
• Track inventory — a yes/no toggle. If set to no, the product can always be bought regardless of stock on hand (useful for made-to-order items).

The value customers see as "available" is usually stock on hand - stock allocated, compared against the out-of-stock threshold.

Making a product "out of stock" manually

If you want a product to show as out of stock regardless of the actual number:

1. Open the variant.
2. Set Stock on hand to 0.
3. Save.

Alternatively, disable the product entirely — this removes it from the catalogue rather than just showing it as out of stock:

1. Open the product (not the variant).
2. Toggle Enabled to off.
3. Save.

Disabled products are hidden from customers and can't be found in search. They're still in Vendure and can be re-enabled later.

Bulk stock updates

If you need to change stock for many products at once, don't do it row-by-row. Export the current stock list, edit in a spreadsheet, and ask your operations team or Flowtech account manager to reimport. This is usually how seasonal stocktakes are handled.
