We have a price increase from january. how do I adjust my prices ?

I can share with you how to adjust the prices of your items, @cfc2015-mweb-co-.

In QuickBooks Online, we can edit each item to adjust the cost. Let me show you the steps how:

1. Select the Sales menu, then choose Products and Services. 
2. Search for the item to modify and click Edit.
3. Scroll down to the page until you'll see the Cost field. 
4. Update the cost.
5. Click Save and close.
   
   

Please note that the changes made will affect future transactions. Hence, the existing one will still use the old cost. You can also review this resource for additional insights on setting up and tracking your inventory in QuickBooks Online.
