# What should I do if my supplier only provides 'in stock' or 'out of stock' status?

If your supplier’s feed contains only text values, such as "in stock" or "out of stock", you can still update inventory using Stock Sync’s Quantity Rules.

Create a rule that checks for text and assigns a quantity value. For example:

= Equal
instock
5

This rule sets the product quantity to 5 whenever the supplier shows "instock". You can replace 5 with any quantity you want to use. When the status changes to "out of stock", you can set the quantity to 0 with another rule. This lets you keep products available until the supplier marks them as unavailable.
