Custom Customer Portal + Payments

$85/hr Starting at $6K

Give your customers a secure platform to log in, view balances/usage, update their information, and pay invoices in minutes. I’ll design and ship a production-ready portal with Stripe Checkout (or Stripe Billing for subscriptions), clear APIs, and a clean, responsive UI—plus docs and training so your team can use it day one.

What you get

  • Branded customer portal: (desktop & mobile) with login, profiles, invoices, and receipts
  • Secure payments via Stripe Checkout (SCA/3D Secure handled by Stripe)
  • Admin console for staff: customers, invoices, refunds/credits, exports (CSV)
  • Reporting: downloadable CSVs and simple dashboards (paid vs. outstanding)
  • Deploy & handoff: Dockerized deploy to your cloud (DigitalOcean/AWS), runbook, and a live walkthrough
  • 15-day/10 Hours Transitional Support (optional purchase, extended support plans will not be charged until after the 15-day period)


Tech & safeguards

  • Backend: Spring Boot (Java) with REST APIs and OpenAPI docs
  • Frontend: Angular/TypeScript, accessible & responsive
  • Database: PostgreSQL with versioned migrations (Flyway)
  • Security: JWT auth, roles/permissions, validated inputs, HTTPS, secrets management (following OWASP standards)
  • Reliability: health checks, structured logs, backup/restore drill


Timeline & milestones (sample: Scope changes will affect timeline)

  • Week 0: Kickoff & requirements freeze

  • Week 1: Data model + API spec; screen wireframes (Milestone 1: 30%)

  • Weeks 2–3: Build portal + Stripe + bookings; weekly demo (Milestone 2: 40%)

  • Week 4: Data import, deploy, training, docs (Milestone 3: 30%)


Ideal for

Utilities, memberships/associations, services with invoices or subscriptions, and any team replacing fragile spreadsheets + manual payments.

  • Your logo/colors
  • Example invoices/fields
  • Existing terms/refund policy
  • Stripe account (I’ll guide setup). 
  • Domain: Use your existing domain (e.g., example.com). If you don’t have one, I’ll help you choose/purchase one.
