Manage a product's suppliers

The Suppliers tab on a product records who you buy that product from, on what terms, and at what price. Each linked supplier can carry a product-level supplier SKU, MOQ, lead time, target stock days, and a price for each of that supplier's pricing tiers. One linked supplier is the default — the source SKU.io uses for the product's Default Cost and for pre-filling purchase orders.

This guide covers linking, editing, and removing suppliers from the product side. You can also attach suppliers inline while creating or editing a product — the Suppliers tab is where you manage them afterwards. Deep supplier management — supplier defaults, supplier pricing tiers across all products, and supplier inventory — lives in the Suppliers area; this tab links out to it wherever that work belongs.

Before you begin

• Permission: editing suppliers requires the products.update permission. Without it the Edit button is hidden and the tab is read-only. See the product permissions reference.
• The supplier must already exist. You link an existing supplier here; you can't create a new supplier from this tab. Create suppliers in the Suppliers area first.
• One person edits at a time. The product uses a pessimistic edit lock shared across all its tabs. If a teammate is editing the product, the Edit button is disabled and its tooltip names who holds the lock. If someone takes over the lock while you are editing, this section drops back to read-only and your unsaved changes are discarded.

Read the linked suppliers

Open a product and select the Suppliers tab. Each linked supplier appears as a row with:

Column	What it shows
Supplier	The supplier name, linked to the supplier's detail page.
Supplier SKU	The supplier's own code for this product, or - if none.
Lead Time	Days from order to delivery. Falls back to the supplier's default, then the global default, when no product-level override is set.
MOQ	Minimum order quantity, shown in the product's stock unit of measure. Blank when no product-level override is set.
Target Stock Days	Days of cover to plan for. Falls back to the supplier's default, then the global default, when no override is set.
Pricing	The price per supplier pricing tier (tier name, price, currency, per stock unit), or No tiers.
Default	A filled check marks the default supplier; the default row sorts to the top.

Each row also has an arrow that opens the full supplier product record in the Suppliers area, where supplier inventory and the complete sourcing history live.

MOQ and pricing are shown per stock unit of measure. If the product's stock unit isn't EACH, that unit is appended to the figures (for example 12 CASE). See configure a product's units of measure.

Edit a supplier's terms

1. Select Edit on the Suppliers card. Each supplier becomes an editable card.
2. Under Product-level overrides, set any of Supplier SKU, Lead Time (days), MOQ, and Target Stock Days. These override the supplier's own defaults for this product only. Leave a field blank to inherit the supplier default (and, failing that, the global default) — the placeholder reads Supplier default to signal this.
3. Select Save. A confirmation toast appears and the tab returns to read-only.

Select Cancel to discard changes and release the edit lock.

Set per-tier pricing

Pricing is captured against each of the supplier's pricing tiers (their cost tiers, distinct from the product's sell-price tiers).

1. In Edit mode, find the supplier's Pricing Tiers section.
2. Enter a price for each tier already assigned to the supplier. Prices are per stock unit, in the tier's currency.
3. Save to persist the prices. Only tiers with a value entered are saved.

Assign an existing tier

1. Select Add pricing tier under the supplier.
2. Pick a tier from the list of the supplier's not-yet-assigned tiers. It's added immediately and the price input is focused so you can type the price.

Assigning a tier applies it to that supplier across all of their products, not just this one — the menu states this before you confirm.

Create a new tier inline

If the tier you need doesn't exist yet:

1. Open Add pricing tier, then under Create new tier enter a Tier name and choose a Currency.
2. Select the check (or press Enter). SKU.io creates the supplier pricing tier, adds it to the supplier, and focuses its price input.

The new tier is a supplier pricing tier owned by the Suppliers area; manage or rename it there afterwards. When a supplier has No tiers at all, the read-only view offers a shortcut to manage tiers on the supplier's page.

Add a supplier

1. In Edit mode, select Add Supplier.
2. Search for the supplier by name and select it, then select Add. Adding a supplier that's already linked is rejected with a warning.
3. Fill in any product-level overrides and pricing, then Save.

The first supplier you add to a product is automatically made the default.

Remove a supplier

1. In Edit mode, select the ✕ on the supplier's card.
2. Save.

Removing the supplier deletes the link along with its per-tier pricing for this product. If you remove the current default and other suppliers remain, the top remaining supplier becomes the new default automatically, so a product with any linked suppliers always has exactly one default.

Set the default supplier

The default supplier is the single source SKU.io treats as authoritative for the product.

• In Edit mode, select Make Default on any supplier's card. That supplier gets the Default badge and every other supplier is cleared, so only one is ever default. Save to persist the choice.

Behind the scenes, setting a default clears is_default on the product's other supplier links and marks the chosen one — linking that supplier to the product first if it wasn't already linked.

What the default supplier drives

• Default Cost. The product's default cost is taken from the default supplier product only. Among that supplier's pricing rows in your base currency, SKU.io prefers the supplier's default pricing tier, then the lowest price, then the lowest tier id as a stable tiebreak. If there is no default supplier, or it has no base-currency pricing row, Default Cost is empty. This cost feeds product financials — see set a product's accounting & financial line type.
• Purchase order defaults. When you raise a purchase order for the product, its default supplier, lead time, and MOQ pre-fill the line, so the terms recorded here become the starting point for procurement.

Because the default determines cost and PO behaviour, review it whenever you add, remove, or renegotiate a supplier.

Next steps

• Set a product's price — the sell-side pricing tiers, separate from supplier cost tiers.
• Set a product's accounting & financial line type — where Default Cost is consumed.
• Configure a product's units of measure — the stock unit that MOQ and pricing are quoted in.
• Edit a product's details and the product detail page reference for the other product tabs.
• For a product's stock on hand, see view a product's stock.

Video transcript

The Suppliers tab records who you buy a product from, and on what terms. Each linked supplier carries its own supplier SKU, lead time, minimum order quantity, and target stock days, plus a price for every pricing tier. One supplier is marked the default. Click Edit to change those terms. Each product-level override applies to this product alone — leave a field blank to inherit the supplier's own default. Enter a price against each pricing tier, then Save. The default supplier sets the product's Default Cost and pre-fills its purchase orders.
