There are two accounting methods commonly use and those are:
1 - Accrual Accounting

1 - Accrual Accounting method is used in which expenses are
recorded when they occur and not when actual cash is paid, In this
method actual cash payment timing is not important for expense or
receipt recording

recorded when actual cash is paid for expenses or cash is received
for services or product and in this method actual timing or expense
or receipt is not important and all transactions are recorded at
actual cash payment time.
