The work was done in March. It's June and you're writing another "just checking in" email about the invoice. Nothing damages a professional relationship quite like having to chase money you already earned.
A Price Quote with payment terms written into it does two jobs: it wins the work, and it settles the payment conversation before the work starts — when both sides are relaxed about it.
Volnyn can invoice automatically once a quote is accepted, so there's no gap between "yes" and the paperwork, and no awkward follow-up message.
You connect your own payment method, so the money reaches your account.
