Accounting system in php – data entry via telegram

There is a system of accounting for arrival and expense

there are 10 accounts in this system, for example.

for each account we keep records - receipt, expense, total income for the month, etc.

The data is stored in a homemade table - in the closed part of the site

If you need to make a parish - write the command just in the telegram bot
Example of the command: "ivanov 3000" - this command means that on the account of Ivanov we record the receipt - 3000
"ivanov expense 3000" - this command means that we deduct 3000 from Ivanovs account
And there are 8 such teams of different pieces

All data is entered manually via telegram.
no integrations are needed

The task is to understand our system of this and make minor changes sometimes
