Heeros Accounting can only be selected for use when a contract for its use has been made with Heeros.
If transactions from Sales Invoices are to be transferred to Heeros Accounting, the accounting interface must be defined as Heeros Accounting in the general settings of the Sales Invoices. Heeros Accounting will only be selectable if an Accounting has been established for that company.
In addition, it should be noted that the corresponding basic information used in the Sales Invoices must also be available in the accounting. Such information includes Accounting accounts, VAT codes, Counters, Cost units, and other accounting objects.
