How do monthly payments work?

Pay up to 10% today and the rest in equal monthly payments, in whole dollars, from $99 a month. Plans of 12 months or less have no fee. Longer plans include a service fee shown before you pay: 6% up to 24 months, 12% up to 36 and 18% up to 60. You use the name from the first payment and it transfers to you within 5 to 7 business days of the last. Renewals that fall during the plan are billed to you as a separate line, at the registry's rate. Stop anytime: payments made are not refunded and the name returns to the seller.

What's in the free brand protection?

One year of Brand Protection Starter, a $99 value, with every purchase on name.ai. We alert you when lookalike domains of your brand are registered, run a one-time check for lookalikes that already exist, watch your new domain for DNS, registrar and expiry changes, and set up a business account your team can share. Purchases over $2,500 also get a dedicated account manager. Plans after the first year start at $99.

How does the transfer work?

Within 5 to 7 business days of payment the name moves into your name.ai account. Keep it there or transfer it to any registrar.

Is there anything to pay later?

Only the yearly renewal, the same as any domain.

Full refund if not delivered

In your account in 5 to 7 business days

Payments secured by Stripe
