When we are called into consult with a new client who either set up POS themselves or had another consultant work on it, the most common problem we see is a negative amount in the POS inventory adjustment expense.  This indicates that the client has not been receiving inventory in properly.  Most commonly, the client will just enter quanities of items in the on-hand field.  While POS does warn you that you are creating an adjustment, you can hide the message and most do.  What is happening is that you are telling POS that you have X qty at Y cost and therefore it increase the inventory and the offset is placed into POS inventory adjustment expense.  Since both accounts are debit accounts, the expense is driven negative. 

How to fix:  First of all, you must receive all inventory in on receiving vouchers.  Secondly, depending on how long this has been going on, the fix can be as simple as changing all of the check/or bills entered from whatever is listed to POS inventory adjustment expense.  We can consult with you regarding the specifics of your case as well as provide training on POS done right.  Give us a call

So version 8 of Point of sale has been out for a few months.  Here are my comments.  The web component is not quite ready for prime time.  It has very limited functionality and NOT a good fit for clothing store at this time as there is only 1 view available for each style and the styles display kind of weird.  We have been promised fixes early next year.  The simple cashier screen is great improvement for touchscreen use.  Please note however that not all of the data entry fields are on the simple cashier view. For example, to enter a customer you need to go back to the old screen. The good news is it is pretty simple toggle.  The currency buttons when taking cash are LONG overdue and really cool.
