Not "another checkout button." A complete recurring-revenue system where billing, access, plans, and product features work as one connected platform.

What Is a Subscription Platform?

A subscription platform is a web application where users, teams, or companies pay on a recurring basis to access software, content, services, portals, dashboards, or premium features.

A good subscription platform does more than collect payments. It connects pricing plans, user accounts, access permissions, billing status, invoices, trials, upgrades, cancellations, and admin controls into one working system.

What you'd outgrow

Simple Payment Form

  • Collects one payment
  • No recurring billing
  • No plan management
  • No access control
  • No customer portal

Useful for one-time products. Wrong tool when you need recurring revenue and a real subscription experience.

What we build

Subscription Platform

  • Recurring monthly / annual billing
  • Plans + trials + upgrades + downgrades
  • Access control by subscription status
  • Self-service customer billing portal
  • Invoices + payment history
  • Failed payment handling
  • Admin dashboard
  • Webhook-driven access changes

A complete recurring-revenue system — every part of the customer billing journey connected to product access.

03The problem

When Recurring Revenue Needs More Than a Payment Button.

We help businesses build subscription platforms where payment, access, users, plans, and product features work together reliably.

Failed checkout

"The payment went through. The user has access. We have no idea why."— the moment every SaaS realizes billing logic and product access aren't connected.

Users need different pricing plans
Paid users need access to premium features
Trial users need limited access
Customers need to upgrade or cancel
Admins need to manage subscribers
Payment failures need handling
Invoices need to be available
Subscription status must control product access
Plans need limits, seats, or usage rules
Billing must connect with the SaaS backend

06Architecture

How a Subscription Platform Works.

A subscription platform needs user accounts, payment provider integration, subscription status tracking, access control, plan rules, billing events, and admin visibility.

Subscription Models We Can Support.

"Six pricing models. One unified billing engine."

08Pricing plans

Plan and Pricing Structure.

Plans should not only change price. They should control access, limits, features, and customer experience.

Pricing

"Each plan tier unlocks different access, limits, and features — not just a different price."

Plan tier

Starter

For individuals or small teams.

Popular
Plan tier

Professional

For growing businesses that need more features, users, or usage.

Plan tier

Business

For teams that need advanced dashboards, integrations, and support.

Plan tier

Enterprise

For larger companies needing custom limits, security, onboarding, and support.

Plan features that vary by tier
Number of usersNumber of projectsNumber of documentsNumber of reportsAI usage limitsStorage limitsAPI accessSupport levelTeam permissionsAdvanced analyticsCustom brandingIntegrations
09Access control

Subscription-Based Access Control.

The platform should know what each user can access based on their plan, role, subscription status, and usage limits.

Access control

"Starter can generate 10 reports. Professional 100. Business invites teams. Expired loses premium features."

Free user access
Trial user access
Paid user access
Expired subscription
Canceled subscription
Plan-based feature access
Usage-based limits
Seat-based permissions
Organization-level access
Admin-only features
10Customer portal

Customer Billing Portal.

Customers shouldn't need to email your team for every billing change. A billing portal gives users control while keeping your team efficient.

Customer portal
billing.portal

Self-service

Customers manage everything. Your team doesn't get the email.

Billing history
Invoices

11Admin dashboard

Admin Dashboard for Subscription Management.

A subscription platform needs admin visibility so your team can understand customers, payments, access, and billing issues.

Admin dashboard
subscriptions.admin

15 control points

Subscribers, plans, payments, failures, revenue — one screen.

12Stripe

Stripe Billing Integration.

The most important part is not only connecting Stripe. The important part is syncing Stripe billing status with your application access rules.

Stripe

"Stripe handles the money. We make sure access matches what they paid for."

Stripe Customer Portal
Stripe subscriptions

Subscription Lifecycle We Can Build.

14Failed payments

Handle Failed Payments, Cancellations, and Access Changes.

Recurring billing needs clear rules for what happens when a payment fails, a trial ends, or a customer cancels.

Failed payment

"Notify customer · keep access during grace period · alert admin · restrict premium if unresolved."

Failed payment detection
Payment retry events
Grace period logic
Account restriction rules
Trial expiration
Cancellation confirmation
End-of-period access
Invoice email notifications
Admin alerts
Customer reminders
Subscription reactivation
15Usage metering

Usage Limits and Metered Access.

Some subscription platforms need more than simple monthly plans. They need limits based on seats, credits, reports, files, AI usage, storage, or API calls.

Metering

"Process 100 documents on Starter. Hit the limit. See the upgrade prompt. Click. Done."

Seat limits
AI credit limits
Report limits
Document processing limits
Storage limits
API usage limits
Project limits
Workspace limits
Monthly reset logic
Usage tracking
Overage rules
Upgrade prompts
16Team subscriptions

Subscriptions for Teams and Organizations.

For B2B SaaS platforms, subscriptions are often attached to an organization, not only one individual user.

Multi-tenant

"One subscription. One billing owner. Ten team members. Role-based access for each."

Organization subscriptions
Team workspaces
Seat management
Billing owner role
Team member access
Company-level plan limits
Organization invoices
Workspace-level usage tracking
Admin-controlled billing
17Security

Secure Subscription Infrastructure.

Subscription platforms handle accounts, payments, customer data, invoices, and product access. The system needs secure authentication, protected APIs, safe billing event handling, and clear permission rules.

Security

"Payment status should control access — securely and reliably."

Secure authentication
Protected API routes
Role-based access
Subscription status validation
Webhook signature verification
Encrypted storage
Audit logs
Admin permissions
Environment variable protection
Payment provider security
User activity tracking
Error monitoring
