Hi RozPiara,
You're absolutely right! In AccountRight (Desktop version), statements can only be generated from invoices, not orders, since orders are considered non-financial until converted. That means they won’t show up in statements until they’re invoiced. The good news is that you can easily convert your orders to invoices. Once you do that, you'll be able to record payments and generate detailed customer statements.
Check out this guide on how to convert a sales order to an invoice: Converting a sales order to an invoice
And for more info on how to generate customer statements, have a look at this: Customer statements
Hope that clears things up!
Regards,
Earl
