Transparent Merchant Pricing

Simple, Predictable Plans with Zero Per-Order Fees

Unlike legacy compliance software that charges transaction percentages or hides behind opaque sales calls, Domillio offers crystal-clear flat rates. Install in minutes, start on our Free tier, and upgrade only as your wholesale volume expands.

All-Inclusive Modular Suite: All plans provide full access to the live Flagship Tax Exemption Desk with automated cross-desk compliance logging. Companion desks activate seamlessly as your store expands.

Frequently Asked Questions About Pricing

Clear answers regarding Shopify Billing API charges, free trials, and server costs.

How does billing work?

All paid plans are billed directly through your standard Shopify monthly invoice via the official Shopify Billing API. You will never be asked for separate credit card details or off-platform payment methods.

Is there a free trial?

Yes! Both Starter and Pro plans include a 7-day completely risk-free trial. If you cancel within the 7 days, your Shopify account will never be charged.

Are there any per-transaction fees or percentage cuts?

Never. Unlike competitors that charge 1% to 3% of your wholesale order value or penalize high-volume stores, Domillio charges strictly predictable flat rates. You keep 100% of your wholesale revenue.

What happens if I exceed my certificate limit on the Free tier?

Your existing certificates remain active and customers continue purchasing tax-free. You will simply be prompted to upgrade to the Starter plan to approve additional new certificates.

Can I switch plans or cancel at any time?

Yes. You can upgrade, downgrade, or cancel your subscription at any time directly within your Shopify Admin under App Settings or Shopify Billing.
