Automatic price increase on 1 category every time a new price is updated

Topic summary

A marketplace owner needs to automatically apply a 20% markup to one vendor’s products whenever prices are updated. The vendor’s prices sync nightly via Shipturtle (a product import app), which overwrites any manual price adjustments made in Shopify.

Current situation:

  • Products import through Shipturtle
  • Nightly price updates from vendor erase manual markups
  • Need automated 20% increase for this specific vendor’s category

Proposed approach:
Implement a script or automation that identifies products by vendor name, tags, or collection, then applies the markup during import/update and saves it back to Shopify.

Open question:
Whether the store owner wants to continue syncing prices from this vendor at all, or only sync inventory while managing prices independently. The discussion is ongoing as details about the preferred workflow are being clarified.

We run a online market store with deferent vendors. One off my vendors prices needs be increased by 20% automatically every time the vendor updates the price on their side.

Is it possible to insert a code on my Shopify store to increase the price of a certain category by 20% every time the price update

@LouiseH

Yes, this is totally possible and depends on how the vendor updates their prices.

If you’re importing their products using a product feed, an app, or the Shopify API, you can build a script or automation that does the following:

Identify the vendor or product category using tags, vendor name, or a custom collection

Apply a 20% markup to the price during the import or update process

Save the updated price back into Shopify

Let me know how the vendor’s updates are currently being handled and I can give you a more tailored solution.

Hi We use Shipturtle to import the products to our website, the problem that we have is our vendor update their price every nite then the new prices import to our shop and clear the price where we did a manual price update

@LouiseH
Interesting. So, do you only want the inventory from your vendor and not the price synchronization?
