Setup, catalogue and checkout.
BEFORE ANYTHING ELSE
Add one product and buy it yourself.
Confirm the entire flow works before building a catalogue.
DECIDE THE STRUCTURE FIRST
Categories, attributes, naming, image sizes, SKU scheme.
Fixing inconsistency across hundreds of products is far worse.
FOR PRODUCT CONTENT
Never use manufacturer descriptions. They appear everywhere and do not rank.
Answer the question that prevents the purchase.
FOR IMAGES
Resize, then compress. Consistent size and background.
Product images are the largest part of a shop's page weight.
FOR PAYMENT
Test mode first, then a real transaction with your own card.
Verify the webhook updates the order automatically.
A broken webhook means payments succeed and orders stay unpaid.
FOR CHECKOUT
Show delivery costs early. Allow guest checkout. Test on a phone on mobile data.
FOR EMAILS
Send from your own domain with SPF and DKIM, or confirmations go to spam.
NEVER
Dispatch on a payment screenshot. Confirm funds in your own account.
