Suggestion 1 :
To create a apps(Android/Apple) which able to used by customer to collect their delivery data such as Sender(Name/Contact/IC/Email), Recipient(Name/Contact/Address), Purchased item and receipt no which linked to system. Then system will verify whether the bill is correct & been paid then only show the complete status. Lastly, all customer data can be collected and uploaded to the database by real time. The other department person incharge only collect the data and proceed the order.
All the same just different in key in customer order by our sales person. So maybe need to have login page with detail of name, outlet, password etc.
