Recording invoices from PO - shorten process

The process of recording an invoice from a purchase order seems very long-winded, and I don't understand why it has been lengthened from Sage 50? Someone creates a purchase order. The goods then need to be marked as received for the order to update to complete once an invoice is posted (this seems strange in itself - there is no column to view whether an item is marked as goods received so it's easy to miss but once an invoice has been recorded there is no way to go back and mark goods as received). Surely by recording the invoice the system could have the option to mark goods as received during this process, without having to do it first? On the goods received screen also you have to enter supplier references, which seems pointless as you will have about 6 more screens to enter this information anyway. Moving on to the next step, where you tick 'record invoice' - a middleman screen appears. I'm not sure the purpose of this screen at all. The figures in the top right do not enter by default, so you have to enter them again from the invoice. Sage does not allow these figures to differ from the PO by even a penny, even for VAT rounding you have to go back and adjust the purchase order, so why do they not just auto fill in? What is the purpose of this screen? It seems the only detail on this screen of note is the invoice date - but this could just be entered on the final screen? At this point, also, any carriage also appears to be lost. We have noticed that if you close this screen and then go to 'record invoice' again, the carriage displays this time, so this is a bit of an odd glitch. From this point you are finally re-directed to the enter supplier invoice screen, where you need to enter the VAT amount again for invoices where it is not a straightforward 20% for all items/0% for all items, and re-enter the second reference. No useful information is transferred to the narrative either, so this needs to be entered as well. Overall, it just seems like a lot of re-entering, and when you are following the full process above for hundreds of invoices the additional time that feels unnecessary really starts to mount. It would be fantastic if Sage could review this whole process with regards to making it easier for the user to enter invoices.
