Subscription Module

devicethread was running subscriptions on an Excel sheet and a raw Stripe link, every payment, renewal, and upgrade tracked by hand. I designed the in-product subscription module that replaced all of it: plan selection, checkout, billing management, and account changes hoteliers could handle themselves. I owned the flows, screens, transactional emails, and edge cases end-to-end. What used to be manual back-office work is now a self-serve experience that matches the rest of the platform.

Challenge

Challenge

Payment processing was a nightmare. The Account team managed multiple spreadsheets, scattered Stripe payment links, and manual email notifications. This created delays, errors, and data inconsistencies as we scaled. The team spent 4–8 hours per week on reconciliation alone. We needed a single source of truth for all payment data and customer information, a system that could grow with us globally.

Solution

Solution

I designed a unified payment platform with three integrated surfaces: a customer-facing dashboard showing payment status and next billing date, an admin dashboard for managing subscriptions and handling edge cases, and automated transactional emails for every step of the payment lifecycle. The solution unified Stripe data and automated reconciliation, dunning flows, and renewal notifications, eliminating manual overhead.

Outcome

Outcome

The system enabled global expansion from the USA to North Macedonia, Riyadh, North America, and Switzerland. Today, it manages 900+ rooms across 30+ hotels. The Account team went from hours of daily manual work to automated processes, reducing errors and enabling faster onboarding. Customer satisfaction improved due to clear payment status and seamless renewal workflows. This system is now the foundation for multi-currency expansion.
