Frequently asked questions

Do I need a credit card to start?

No. Starter is free and includes 100 API calls a month. Upgrade whenever you're ready.

What counts as a merchant?

A business on your platform that you add in Ziptax to track nexus and calculate tax. Starter covers up to 3. Pro and Enterprise have no limit.

What happens if I go over my plan?

We'll let you know as you get close. On Starter, move to Pro to keep going. On Pro, service keeps running and extra calls are billed at your plan's overage rate.

What is the TaxCloud compliance integration?

Invite merchants who want full-service compliance to TaxCloud. Their TaxCloud account links to your platform, and TaxCloud handles registration, filing, and remittance for them.

Can I change plans later?

Yes. Upgrade or downgrade anytime from your Ziptax dashboard. No need to contact us.

Monthly or yearly?

Monthly keeps things flexible. Yearly saves about 15% and gives you a predictable bill.
