My company raises Purchase Orders for hiring small equipment, but at the point of raising the order, we do not know what the 'top-up' fuel cost will be.
Is it possible to dictate that the invoice line relating to the equipment hire has to match exactly to the PO, but that there can be a variance of say, £10, or a % of total invoice value for the fuel element?
I understand variances are set at company level, but is it possible to also set varying tolerance levels by supplier, as some suppliers provide 'big ticket' items running to £000's whereas other suppliers have very small invoices totalling less than £20. For example, selecting a % doesn't necessarily work, as 10% of £2000 would be £200, which would be too high, whereas 10% of £20, i.e. £2 would be acceptable.
