Due to the change that already closed invoices cannot be rewritten to company, it is mandatory that MEWS absolutely does not close any invoices automatically. Payments that are received directly after posting, for example, are posted directly against the product and the invoice is closed. Here I can not change the company address from now on. However, on this first invoice the tax statement is visible. If this invoice is charged back and recreated so that it is issued to the company, unfortunately the tax statement is missing here. MEWS is no longer allowed (at least in Germany) to automatically close invoices if the check-in / check-out has not yet taken place.
