Ecommerce build: Red flags
Each of these signals has a mechanism behind it. They are not "beware of cheap offers", they are specific things you can see in the document in front of you.
What to look for in the document in front of you
A migration with no mention of redirects
If you are moving an existing shop and the offer does not contain this line, it is missing from the plan too.
A price with no product count
The difference between 50 and 5 000 items is a difference in price, not in opinion.
Payments "later"
Connecting a bank or payment provider has a lead time outside the provider’s control. It starts at the beginning, not at the end.
A demo with sample products only
A beautiful shop with three mugs looks different from yours with 800 items and long names. Ask for a demo with your own data.
