I can make this pretty easy for you.
First, whenever you see someone offering app or web design for a ridiclously low price, imagine your business setting on fire with all your stock, employees, and customers trapped inside.
Secondly, research the going rate for services like app design in the real world. In some countries (where a dollar goes a bit further), it may be possible for developers to still profit by offering services at 20% to 30% less than in places like the US. Some (seller) costs, though, won’t change.
- App design software licences will remain the same
- Template costs and costs associated with including premium things like WooCommerce apps will remain the same
- PC and associated hardware costs remain the same
It really isn’t a good idea, therefore, to go with a super budget seller, if what they offer sounds to good to be true.
The best thing to do is list all your app requirements, send messages to sellers with a few hundred reviews or more, asking if they can help. Then ask for a quote, estimated order turn around time, and ideally, links to apps which they have created previously.
If I was an app designer, I would have a free app available for clients to test drive or links to past work which I am proud off. I’d, therefore, be a bit insistent about this bit.
