What it does for you
Recurring invoices make themselves
You save a schedule once: the client, the lines and the cadence. Every month, every quarter or every year, whichever fits. On the agreed day factuurmaken creates the invoice with the next invoice number, and sends it to your client straight away if you want.
That does not just save time, it mainly saves the invoices you would otherwise forget. A subscription you failed to invoice in March does not get invoiced in July after all.
Your bookkeeper looks along for free
Instead of handing over your password, you give your bookkeeper access to the invoices you have sent. That costs nothing and does not use up a team seat: your bookkeeper works in their own free bookkeeper account and can only look and download, never change anything. Your partner or the colleague who actually does the admin you invite as a team member, with their own login and their own permissions.
When someone leaves, you remove their access without having to change your own login anywhere.
E-invoices for clients who ask for them
Governments and large organisations increasingly no longer accept a PDF and want a UBL file their system reads automatically. You export the same invoice as UBL, in NLCIUS or Peppol BIS 3.0, and you can set the XML to travel automatically as a second attachment with your e-mail.
In focus: two administrations side by side
If you run two companies, or a holding with an operating company, each needs its own company details, numbering, clients and settings. Letting them run into each other is exactly the sort of thing you regret in an audit.
On Business you keep two administrations separate within one account, with one login. You switch between them without logging out, and the number sequences stay strictly apart.
