Check Supply

Project Overview

Check.Supply is an iOS app designed to simplify check mailing by providing a cash app-like experience for sending physical checks. Leveraging Plaid for bank account verification, the app allows users to send checks digitally, tracking the entire printing, mailing, and delivery process.

Technical Implementation

The creators developed a custom check printing solution after finding existing API providers unsatisfactory. Key technical components include:

• Bank account verification via Plaid
• Real-time check tracking
• Integrated KYC (Know Your Customer) checks for suspicious payments

Market and Use Cases

The app addresses niche payment scenarios involving traditional payment methods, such as:

• Paying landlords who only accept checks
• Compensating service providers like gardeners
• Handling transactions requiring physical check documentation

Community Insights

Developers and potential users provided constructive feedback, highlighting:

• Existing market demand for simplified check mailing
• Technical challenges in building payment infrastructure
• Importance of secure bank verification and fraud prevention

Design and Development Observations

Commenters noted the project’s professional landing page, suggesting the use of pre-built Tailwind UI templates as a quick, effective design strategy for technical founders lacking design expertise.
