Sales and Billing 
The sales and billing procedure in Poland differs slightly from the standard, to take into account the creation of tax invoices (and correction tax invoices), which the law requires you to prepare. The system automatically creates:
· Tax invoices for all invoices involving VAT (value-added tax)
· Correction tax invoices for any credit memos or debit memos that you create
In order for the system to create the correction tax invoices correctly, follow the procedure described below.
You have customized the pricing procedure (which contains information required by the tax invoice) and the output (which generates the tax invoices and correction tax invoices).
If you want to use the VAT Register, you have set up the Automatic Transfer of Billing Date to Accounting Documents function.
