To create new items from the main admin menu navigate to Sales->Items and click on the top left button New Item.
Click Save to save all the item information.
This is very specific example that will show you how to link an item to invoice with all the fields explained.
Navigate to Sales->Invoices and click on the top left button create new invoice and fill all the necessary information for this invoice.
On the top left Add item dropdown you can select your predefined items that will be auto inserted into the preview item area without you needing to fill all the necessary item information manually.
In previous versions, the item had a field for a rate which you was using as general rate eq for your base currency, but the problem was that in case customer has different currency than the base currency the rate won’t be accurate when selecting the item from the drop-down when creating invoice/estimate/proposal.
Perfex CRM can bill in your base currency or in the customer currency if configured in the customer profile.
Let’s assume that your base currency is USD and you have a customer which is using EUR currency when you created the item you has added the rate as in your base currency (USD).
When you navigate to Sales->Items and try to create/edit item you will be able to see that new field for rate in EUR will be shown, in this case when you create invoice/estimate/proposal and select a customer that is using EUR currency and then select an item the EUR rate will be auto-populated in the preview area for the item before you add it to the table. This will help you to add the item’s rate only once and then re-use it.
Keep in mind that the rate for other currency will be shown only if customers have configured to use another currency than the base currency.
