The BestInvoicing API offers programmers the possibility to link their own software to BestInvoicing. For example, you can automatically create customers or invoices in BestInvoicing from the data in your own programs, or retrieve customer data from BestInvoicing for reuse. A classic example is linking your own webshop to BestInvoicing in order to create a customer file and corresponding invoice in BestInvoicing, for an order that came in through your webshop.
