My question was also in regards to duplicate purchase invoice numbers not sales. Re: duplicated invoice numbers Agree this should be a difficult "feature" to add in fact shouldn't even be considered a feature it should be a staple inclusion for basic internal controls in any accounting system. I have had multiple dramas with reconciling accounts and invoices being "double-paid" because invoices get uploaded to the In tray twice and the duplicate invoice number is not picked up. An ETA for having this resolved would be much appreciated
