OpenCart (ocStore 3.0.3.7) to bring to mind the ordering process.

Connected Robokassa (still in test mode)
Also purchased and installed modules:
– Simple
– "Payment in 20 ways".
– Delivery of Yandex Go
– Telegram alerts

The desired ordering algorithm is as follows:
1. Customer makes an order: leaves address*, phone*, name, e-mail
2. the manager receives an alert to the mail and telegram (it works)
3. the manager checks the possibility of fulfilling the order, calculates the cost of delivery (preferably using the Yandex Go module)
4. The manager contacts the client, edits the order if necessary, sends a link to pay to the client
5. The client pays, receives a notification of payment to the manager in the telegram
6. The order is transferred to work in the kitchen and for delivery to Yandex Go


At the moment, the module "Delivery Yandex Go" does not calculate the cost and does not work at all fully as in the description.
If you manage to deal with it, it would be good, if not, then you can manually transfer orders.
