What the first build should solve
Direct answer: Customers need clear expectations before checkout about what happens if an item becomes unavailable. Some prefer substitutions, others want confirmation, and some want automatic refunds.
Detailed answer
How this product usually needs to be structured
Customers need clear expectations before checkout about what happens if an item becomes unavailable. Some prefer substitutions, others want confirmation, and some want automatic refunds.
A strong product flow lets the shopper choose a substitution preference, see suggested alternatives where possible, and receive updates if the basket changes after ordering.
Think It Digital can help map this operational logic into the customer app and admin workflow so stock issues do not turn into support chaos or weak retention.
