C-Band Mailbox

A production virtual mailbox SaaS with end-to-end payments, billing and payouts.

Overview

A production virtual mailbox SaaS platform built with Next.js and NestJS.

I focused on the money side of the product: payment and subscription systems, custom billing and invoicing, automated payment collection, commission calculation, provider invoicing and payout workflows — the pieces that have to be right every time.

Alongside engineering I handled SaaS project management, keeping scope, priorities and delivery aligned with the business.

What mattered

  • Subscriptions, custom billing and invoicing
  • Automated collection, commission calculation and provider payouts
  • NestJS backend with a Next.js frontend
