SaaS Development Service
Build, maintain, and scale your SaaS application with senior engineers. From authentication to billing, we handle the full stack.
Scaling a SaaS Product Without a Full-Time Team
Building a SaaS product is a marathon, not a sprint. You need consistent, high-quality development over months and years — but hiring a full team is expensive and risky before you have product-market fit. A two-person engineering team in Western Europe costs over €200,000 per year in salary alone, before you factor in equipment, tools, and management time.
Most SaaS founders start with freelancers and agencies, but the code quality varies and there is no long-term commitment. When your freelancer moves on, your codebase becomes a liability. The next developer spends their first month untangling spaghetti code instead of shipping features, and you are paying for that ramp-up time.
SaaS products have unique technical requirements that generic developers often underestimate. Multi-tenancy, subscription billing, usage tracking, role-based permissions, team management, API access — these are table-stakes features that need to work flawlessly. Getting them wrong early means expensive rewrites later when you have paying customers depending on your product.
The subscription model also means your product is never "done." Users expect regular updates, bug fixes, and new features. You need a development partner who understands your codebase deeply and can ship improvements consistently, not someone who has to relearn your architecture every time they pick up a task.
AsyncForge is designed for exactly this. A subscription that grows with you — from MVP to scale. The same senior engineers working on your product month after month, building on a codebase they know deeply. Start with the Light plan at €2,000/month and upgrade as your product gains traction.
What You Get
Multi-Tenant Architecture
Proper workspace and organization structure built for scale from day one. We implement tenant isolation at the database level so customer data is never mixed, while keeping the architecture simple enough that you can reason about it. This foundation supports everything from single-tenant deployments to thousands of organizations without requiring a rewrite as you grow.
Subscription Billing
Stripe integration with plans, trials, invoicing, and usage-based billing. We build the complete billing lifecycle: plan selection, checkout, trial management, upgrade and downgrade flows, failed payment handling, and cancellation. Your billing system works reliably so you can focus on building product, not chasing payments.
User Management
Roles, permissions, team invitations, and SSO-ready authentication. We implement granular access control so workspace owners, admins, and members each see and do exactly what they should. Team invitations with email verification, and an architecture that supports SSO integration when your enterprise customers demand it.
API Development
Public and internal APIs with versioning, rate limiting, and documentation. If your SaaS needs a public API for integrations, we build it with proper authentication, pagination, webhook support, and interactive documentation. Internal APIs are structured for your frontend with clean data contracts and consistent error handling.
Dashboard & Analytics
Real-time metrics, charts, and reporting for you and your customers. We build dashboards that give your users actionable insights from their data, and admin dashboards that give you visibility into key business metrics like MRR, churn, and user engagement. All charts use accessible, responsive components that look sharp on any device.
Scalable Infrastructure
Database optimization, caching, background jobs, and horizontal scaling. We design your infrastructure to handle growth without expensive rewrites. Connection pooling, query optimization, Redis caching, and background job processing are implemented from the start so your app stays fast as your user base grows.
Technologies We Use
How It Works With AsyncForge
Start your subscription
Choose the plan that matches your current development pace and connect your existing codebase or start fresh. We onboard quickly — within a day, our engineers have access to your repository and understand your architecture well enough to start delivering.
Prioritize your roadmap
Add features and tasks to your Kanban board in priority order. You control what gets built and when. We can help you break down large features into shippable increments if needed, so you get value continuously instead of waiting weeks for a big release.
Consistent delivery
We work through your backlog, delivering production-ready code on the cadence your plan defines. Every feature includes tests, documentation, and clean integration with your existing codebase. You review, merge, and deploy on your schedule.
Scale with confidence
As your SaaS grows, we handle increasingly complex technical challenges — performance optimization, database scaling, security hardening, and new feature development. The same engineers who built your foundation continue to evolve it as your needs change.
