The owner learns the software because they bought it. The staff learn it only if somebody teaches them.
A common pattern: the owner bills confidently, the staff avoid it, and the shop ends up running two systems — the app for the owner and paper for everyone else. That is worse than either alone, because the books are now split.
Training the people who will use it daily is what closes that. It works best aimed narrowly: the five screens the counter actually touches, in the language the staff read, rather than a tour of everything the app can do.
Their own logins and roles.
Billing, payments, stock.
With the owner nearby for a week.
When new staff join or something changes.
How you get help: written answers in the help centre, tickets you can follow, and email, chat and phone during support hours, with onboarding and training when a business is getting started.
Onboarding and training matter in the first month; the help centre and tickets are what you use after that.
What makes staff use practical.
The people who will use it daily — usually the counter, not only the owner.
The few screens used every day, rather than everything the app can do.
English and ten Indian languages, chosen per person.
A shop running the app and paper at once is worse off than a shop running either.
