What should I look at in a Shopify store’s theme customizations before I take over?

Ask first who made the changes. A seller who edited the code personally may be the only person who understands it. A freelancer or agency may still hold the files. Request a copy of the current theme, a list of edits and any notes on why each was made. If the work was done by someone else, confirm that you are allowed to keep and modify it.

Then test how it behaves. Load the store on a phone, in several browsers and on a slow connection. Place a test order. Look for slow pages, broken layouts, odd gaps and features that only work in one place. Customizations that sit on top of the original theme are easier to maintain than ones that rewrite it.

Finally, ask what happens at update time. Does the seller keep a backup copy before every change? Is there a test version of the store? A customization you cannot update safely may force a rebuild. Get a sense of that cost before you decide, and plan a quiet period after closing to learn the setup. Ask for screenshots of how the store looked before the changes, so you can judge what the work really added.

Key takeaways

• Ask who built the changes and whether you will get all the files.
• Test on a phone and a slow connection, and place a test order.
• Ask how updates are handled and whether a backup copy is kept.
