Do service providers need to send an invoice to MeasureMatch to receive payment?

That all depends on where you're based.

1.   If you are not based in the United Kingdom...

We don't need an invoice from you to receive your payment. You’ll be paid via our system. Your payment will not include VAT. However, if you're required by law in your country to have a VAT invoice, then please send it to us.

2.    If you are based in the United Kingdom, but not subjected to VAT ...

We don't need an invoice from you for you to receive your payment. You’ll be paid through our system.

3.    If you are based in the United Kingdom and subject to VAT...

Yes, we’ll need an invoice from you.
