In the first image the lines change to yellow to highlight that an error mat be about to occur. This is a very good feature.
In the second image the third appears as “0” even though there might be one in stock but not entered into Sage for whatever reason. It could happen and has happened that this goes unnoticed especially when busy. The result is an item goes out the shop without being paid even though it’s no fault of the customer. It is only discovered when the invoice is being updated as this can’t happen due the item not having been entered into stock.
If Sage could put in a similar “Highlight warning” to the other image then that would be a great job and top class feature.
Years ago (early 1990s), when working in mail order retail which also had a counter where people could come in and buy over the counter, the system we used printed out a copy of the order (on a specific printer): counter sales staff entered an order and could get it immediately invoiced (updating the accounts), printed and have the warehouse staff to pick it for them to give to the customer - the invoice could not be printed if the accounts weren't updated.
An alternative to highlighting such errors would be to improve updating the ledgers for a "shop" customer to make it more streamlined (it's a bit of a faff at the moment when doing individual orders) and make it impossible to print an invoice unless the ledgers have been updated, eg as a global configuration (on cash payments?).
In my current job which uses Sage, we don't have stock items: is there a highlight if there is insufficient stock for an item?
I really hope Sage can do this.
