vendor refused to give the invoice..how to show purchase of equipment?

Take a Delivery Challan from him On 31st of March. and Invoice in Next year

what if he refuses there any way left to show the transaction in previous year ??

U can pass this entry:

Asset/machinery..debit

To GR-IR clearing account

when invoice comes:

GR-IR clearing account...debit

To Vendor account

basically u cant credit vendor account without supporting document..but u can debit asset account as u have the control and possession
