SaaS Development Services | Next.js + Supabase

Most MVPs land between $25K and $60K depending on the number of user roles, billing complexity, and third-party integrations. A single-plan product with basic auth and Stripe checkout sits closer to $25K. Multi-tenant apps with SAML SSO, metered billing, and admin panels push toward $60K-$80K. Enterprise platforms with compliance requirements, audit logs, and complex permissioning can run $100K-$200K. We'll give you a fixed-price quote after the scoping call — no hourly surprises.

Three reasons: speed, cost, and iteration velocity. Next.js on Vercel gives you edge deployment with zero server management — your TTFB stays under 200ms globally without configuring a single load balancer. Supabase gives you Postgres, auth, real-time, and storage in one managed service that costs $25/month at launch. And because both your frontend and API routes live in one Next.js repo, a single full-stack developer can ship features that would require separate frontend, backend, and DevOps roles on Rails. You move faster with fewer people.

A typical SaaS build runs with 2-3 people: a senior full-stack engineer who owns the Next.js app and Supabase integration, a product engineer who handles UI components and user flows, and a technical lead who reviews architecture decisions, manages Stripe webhook logic, and handles the deploy pipeline. For larger projects we'll add a dedicated designer or a second backend engineer. You'll have a shared Slack channel and weekly demos on staging.

Yes, it's one of the things we build most often. We've shipped both patterns: shared-database with Supabase RLS policies isolating tenant data at the row level, and schema-per-tenant for clients with strict compliance needs (healthcare, finance). RLS is our default recommendation because it's simpler to maintain and Supabase makes the policies declarative. We'll advise on the right model based on your data sensitivity, tenant count, and regulatory requirements.

That's one of the biggest wins of this stack. At launch, most SaaS products run on Supabase's Pro plan ($25/month) and Vercel's Pro plan ($20/month). Add Stripe's 2.9% + 30¢ per transaction and Resend for transactional emails at $20/month. You're looking at under $100/month in total infrastructure until you hit thousands of active users. Compare that to a Rails or Java app on AWS that easily costs $500-$2,000/month before you have a single paying customer.

We handle all of them — and there are more than most founders expect. Failed payment retries, subscription pauses, proration on mid-cycle upgrades, coupon/discount codes, tax calculation via Stripe Tax, invoice PDFs, dunning email sequences, and webhook idempotency. We've integrated Stripe Billing on 200+ projects, so we know exactly which webhook events to listen for and how to keep your local database in sync when Stripe processes events out of order. You'll get a billing system that doesn't leak revenue.

Every project includes a 30-day post-launch support window for bug fixes and deployment issues at no extra charge. After that, we offer monthly retainers starting at $3K/month for ongoing feature development, performance monitoring, dependency updates, and Supabase/Vercel config management. About 60% of our SaaS clients stay on a retainer because they'd rather keep the team that built the product than onboard new developers.

Both work. If you've got Figma files from your own designer, we'll implement them pixel-perfect using Tailwind CSS and Radix UI primitives. If you need design, our product designers will create a component-based design system in Figma before we write any code — typically 1-2 weeks for a full SaaS app. Either way, you'll end up with a consistent UI built on reusable components that your team can extend after handoff.
