A Portal Your Customers Actually Use
A branded, token-authenticated self-serve portal where customers manage cards, subscriptions, and invoices — plus a cross-merchant switch for buyers who shop across your portfolio. No passwords, no tickets, no awkward handoffs.
Hosted at your own subdomain — e.g. portal.greenfieldbakery.com
Self-Serve Without Lowering the Bar
Polished enough that customers use it. Opinionated enough that support tickets drop.
Branded Self-Serve
Customers update cards, pause or cancel subscriptions, and download invoices themselves — cutting support volume without cutting the experience.
Cross-Merchant Switch
When the same customer buys from multiple merchants in your portfolio, the portal recognizes them and offers a safe, token-bound switch between accounts.
Zero Password Overhead
Portal access is granted via signed tokens, so customers never manage another password — and you never manage another credential leak vector.
All the Actions That Used to Be Support Tickets
Every portal action is audit-logged, webhook-emitted, and respects your merchant’s permissions.
Add, remove, and set a default card
View active plans with next charge date
Customer-initiated pause with reason
Cancel at period end or immediately
Pay, download PDF, or view payment history
Signed link with 7-day TTL
Same Customer, Different Merchants, Same Login-less Experience
For ISOs and multi-brand operators, a single customer might buy from three of your merchants. FinMI detects the overlap (same email within the same ISO scope), shows a switcher in the portal, and issues a freshly-signed token bound to the target (customer, merchant) pair on each switch — so tenant isolation is never violated.
The Recovery Loop, Closed
When dunning emails a customer a signed update-payment link, it lands on the same branded portal. The customer updates their card in a hosted Collect.js form, we refresh the vault, and the retry runs automatically. One click, no password, no cart abandonment.
How the FinMI Portal Compares
Full self-serve, cross-merchant aware, and recovery-native — without a custom build.
