If you use Exact Online for your accounts, you can push invoices across from Catermonkey with a single click. Once you've connected the two, an Exact button appears right on the invoice, no copying figures, no switching between tabs to re-enter the same details. Exact Online is one of the most widely used accounting packages in the Netherlands, so there's a good chance your bookkeeper already knows their way around it. Keeping your invoices in one place makes end-of-month reconciliation a lot less painful. You can find Exact Online at https://start.exactonline.nl.
