We built Nusii to be as streamlined and as easy to use as possible. This meant we limited certain functionality, and an integrated payment system was one of the functions that was put on hold...Temporarily.
Getting paid is an integral part of any business, which is why a Stripe and PayPal integration is on our feature list.
We cannot give an exact date on when this will be ready, but it will be happening soon.
