You’ve spammed this loads of times over the last few days - it probably hasn't been answered because there are no requirements. What is a sale? A sales order? A fulfilled sales order? An invoiced sales order? An estimate/quote? Receivables - is this all $ hitting a certain G/L account? Or just paid invoices? Do you factor any margins into this? Or is it cash flow, so you’re also bothered about vendor bills? Is it 30 days or a period? Which date do you want to use on the transaction? Etc etc
