Invoices that add up, and what you keep from them

What an invoice must include

The Belastingdienst sets requirements for invoices. Mizara fills in your fixed details and lets you add what changes per invoice. A complete invoice includes, among other things:

• your name, address, KvK number and VAT identification number
• your client's name and address
• a unique, sequential invoice number and the invoice date
• a description of what you delivered and when
• the amount excluding VAT, the VAT rate and the VAT amount per rate

The full list is in the invoice requirements of the Belastingdienst (in Dutch). Reverse-charge VAT and foreign clients require extra details.

From quote to invoice

Send a quote first. Your client can view and sign it online. Once they agree, you turn it into an invoice without retyping anything.

For fixed monthly amounts, such as a retainer or maintenance, use a recurring invoice. Mizara creates it again at the scheduled time.

Getting paid

Want clients to pay straight away? Connect your own Mollie account and your client gets an iDEAL payment link. That's optional; a regular bank transfer works too.

If a payment doesn't arrive, send a reminder from the invoice and later a final notice. When the payment shows up on your bank statement, you match it to the invoice when you import your statement.

What do you keep from an invoice?

For each invoice you see what the client pays, which costs you've linked to that job, and roughly how much income tax and Zvw the invoice adds to your year. What's left is an estimate of what you really earn.

Mizara doesn't use a fixed percentage for that tax, it calculates over your whole year. Why that matters is explained in how much tax to set aside.
