An ecommerce app development company, with a portfolio of 10 Shopify apps and serving 12,000 active merchants, is refocusing its efforts on a single app. As part of this strategic adjustment, they are offering the Payster app for sale. Payster is an application designed to send automatic email reminders for orders where payment has not been completed, particularly useful for payment options like bank transfers or cash on delivery, predominantly used in Europe. With Shopify expanding its functionalities for delayed payment methods, Payster offers enhanced features since it allows customization of reminder content and includes a dashboard to track unpaid orders, unlike Shopify's native solution. The company built Payster to meet client needs and made it publicly available. However, given that it's the only email-focused app in the portfolio, and not being specialists in this domain, they have chosen it as the first app to divest. Key aspects of Payster include its profitability and low operational costs, hosted on Heroku and using Mailgun for email services. The app currently has approximately 100 monthly paying customers. Interested buyers need a Shopify Partner Account for app transfer. The sale includes the app’s codebase, user base, and domain. Technologies involved include hosting on Heroku, email delivery through Mailgun, and support tools like Cloudflare, Intercom, and Sentry. Potential buyers are pointed toward an app listing for further description and details.
