It's all about when you commit that change. I prefer to do it when the invoice is marked PAID. At that point, subtract your stock. If an error was made, you'll have to either mark it UNPAID, at which point all those items get put back into stock, or have some other form of manual adjustment option.

Ya ...RICHARTS I understand thanks

But what if

         I did make wrong written qty on the invoice....after several days later the customer told me HE GOT 2 MORE ITEMS (flipflop for instance)

         How to corrected my qty onhand

Thanks alot

Sorry..how to correct my qty onhand

I meant...

Qty onhand=12
I wrote on the invoice 5 (flipflop for instance)
Than as the customer received the items he told me that he received 7 flipflop

CAN I STRAIGHT CHANGE THE NUMBER ON THE INVOICE

BUT WHAT IF THE CUSTOMER RECEIVED LESS THAN 5 (ONLY RECEIVED 3 for instance)

HOW TO ADD MY QTY ONHAND

Thanks

Ideally you wouldn't change anything. You'd put another order in which would be a correction. At least that's how I'd do it. But it's up to you.

I think you are right RICHARD...I will follow
thank you very much

It's like if you go to a store and buy a bunch of clothes, and then, let's say you come back a few days later and you want to return a few things off that order but not the whole thing. They won't edit the original order; that one stays put because it'll mess up the accounting that's already finished and done with. The credit cards have been batched and all that's done. But what they'll do is they'll put another order in the system, which is a return, and then that will add those items back into inventory. So you don't go back once an order is processed and posted or whatever you want to call it. Once it's closed, you don't mess with it again. You leave it. If you need to make corrections, like a refund or putting things back in the inventory, you process a second order.

I SEE
I HAVE GOT what you mean
it is very clear

THANK YOU VERY MUCH
