If you export to an inventory system you will need to make sure the correct amounts are being sent. ALM have an unusual way of putting free products on their invoices. You may have noticed doubled up lines, which is what they do for the product they're giving you free of charge. The 1st line they charge you for the product, then the 2nd line they minus it away, but they do charge you a small amount for the delivery fee for each product. So if you see negative signs on any of the lines you will need to edit them as follows.
Luckily they are easy to do, you just need to edit the unit price of the 1st line, to the delivery fee, then delete the 2nd repeated line (the one with a negative on it). Usually the delivery fee is 0.59 cents, but you will need to check your invoice to see how much it is.
I have provided a couple of screenshots below which show you what to look out for and what it looks like after it's been edited.
I'll start by explaining what the 2 ginger beer lines are for on the invoice below; You will need to take a goood look at the 2 images, so if they are too small you can right click it and select 'open in new tab' or just enlarge your whole page by using 'CTRL' & '+'
On this invoice you'll see they've charged $36.94 on the 1st line, then the 2nd line they minused $36.29, which = .65c
If you remove the 10% GST from the 65 cents, you get 59 cents, which is the delivery fee cost highlighted in yellow.
Step 1 is to select the unit price of the 1st line (the line above the one with a negative on it), & change the unit price to .59 cents (to the delivery fee cost)- Keep in mind your invoices may have a different figure for the delivery fee, to know this just look in the delivery fee column.
Step 2 is to delete the 2nd line (the one under it with the negative sign) - in image #1 below they are the pink lines you need to trash
Then check the total is correct and save.
Note that if you have several free products it's best to adjust one product at a time. For eg edit the unit price on one line, then trash the other line, then go to the next product & do the same. Between editing each product, check the total is correct in-between each one. Otherwise it can get confusing which one you're dealing with.
