Billing software and invoicing software are used by companies to create invoices (billing documents) for deliveries and services. Invoicing software usually involves checking and processing the invoice and immediately posting the transaction to appropriate accounting accounts. The verification of invoices, incoming invoices and other documents can also be supported by workflow functions of the billing software. This is done either via interface or directly in an integrated accounting software. As a rule, the invoicing software should be oriented towards the type and volume of invoices that the company processes. There are cloud solutions as well as on-premises solutions in the area of invoicing. In addition to invoicing software, you will find numerous solutions for quotation and order processing, merchandise management and costing systems.
