Hi,

I assume you are saying you expect payment within 30 days from the end of
the invoicing month. If so:-

=(EOMONTH(B2,0)+C2)-D2


Format as general. A negative value would indicate late payment.
If you get a #NAME error then

Ok I need to find out how long it takes our customers to pay an invoice, i
need to know if its xx days early or xx days late.

Column B has the invoice date
Column C has payment terms - usually 30 days end of month
Column D has payment date was received
Column E would have my answer in it either as -xx for days early or just xx
for days late.
