If my supplier suddenly increases prices, is there a way to automatically update pricing without hurting my margins or pausing ads?
Nice question @ChristinWang this happens a lot in dropshipping 
The best way is to set up automatic pricing rules so your selling price adjusts when supplier costs change. You can use a fixed multiplier (e.g., 2.5x–4x) or profit margin rule. That way, if the cost increases, your price updates automatically → protecting your margin and no need to pause ads.
Also, with tools like Zopi, you can automate pricing and quickly switch to better suppliers if costs go up, so you’re not stuck with low-profit products.
