When entering Purchase Invoice, is it possible to enter the Total Amount and have the Line Amount prior to tax calculate automatically?
E.g. if I wanted to enter an Ontario invoice for $100 + 13% HST Tax of $13, is it possible to enter $113 into the system and have the $100 Expense item automatically calculate?
Note, we are not using inventory items or such. The scenario above mostly relates to reimbursement of mileage whereby an employee submits an expense report for kilometers driven for business use. The Canada Revenue Agency allows us to claim a refund on a portion of this charge (ITC). So the employee's expense report asks to be reimbursed $200. Using Ontario again, there would an amount of approx $23 ($200/1.13 deducted from $200), so I'd like to simply enter the $200 Total Amount in the Purchase Invoice and have the system back-calculate the Amount Prior to Tax, $177 in this case and a tax amount of $23.
Any guidance on this is appreciated.
