After you have changed your routine for expensing product costs, you should also take a look at which method for posting purchase invoices in Mamut is most appropriate for you.
Manual Posting of Purchase Invoices in Journal Entry
By manually posting purchase invoices in the Journal Entry section of the software you now need to remember not to use the default cost accounts for product costs when registering
your journals. This is because you should first use the cost account when the outgoing invoice is posted. Thus, you need to use the N/C Accruals non-received invoices N/C 2110
as the double entry N/C for the products included. VAT has to be posted in the usual manner.
If you decide to post purchase invoices manually, you will lose the link between posted purchase and stock movements that are created. Thus, you cannot correct the stock value
in the balance sheet when posting purchases, and any costs such as freight/forwarding will not influence the value in the balance sheet either, should you want to include these in the
first place. Therefore it is recommended that you use the Purchase module where possible to post purchase invoices.
Posting Purchase Invoices via the Purchase Module
If you decide to post purchase invoices via the Purchase module in Mamut, this will make it possible to correct any possible differences between the product’s receiving value and the
posted value of the stock value in the balance sheet. Additionally, freight/forwarding etc. will be taken into account in the product’s stock value in the balance sheet, if you made the
relevant settings for this. Posting purchase invoices via the Purchase module is done by going to View – Purchase Order – Purchases, and finding the purchase you want to post to your accounts. Click on Post Purchase Invoice (Ctrl + B) and fill in the correct information. Click Invoice to post the purchase invoice.
