◆ The short answer
SaaS development is the work of designing, building, launching, and growing a subscription software product. Typical SaaS engagements take 12 to 20 weeks and start at mid five figures. We do strategy, design, engineering, billing, and launch under one roof so you do not have to glue four agencies together.
◆ TL;DR
- Built on Next.js, TypeScript, Postgres, and Stripe by default.
- Multi-tenant architecture from the first commit, not bolted on later.
- Billing, auth, and admin tools included, not extra line items.
- Launch and growth instrumented before paid acquisition starts.

◆ How we build it
Three phases. Three demos. One live product.
Discover
A short discovery phase. We frame the riskiest assumption first, sketch the user, and agree on what we are actually shipping. By the end you have a written brief, a clickable prototype, and a fixed scope you can sign off.
Build
Iterative build cycles with weekly demos. Engineering joins at the design table from day one, so design and code move together. Feature flags on anything risky. Production observability built in from the first commit.
Launch and scale
Soft launch to a closed beta. Telemetry on every flow. Then a coordinated public launch and the unglamorous scaling work: auth, queue depth, database read replicas. We stay in the trenches after launch, not before it.
◆ What you get
Concrete deliverables.
Every engagement produces artifacts you can hand off, build on, or hold us accountable to. No abstract decks.
- A live SaaS product on a domain you own
- Stripe billing with subscriptions, trials, and dunning
- Auth, multi-tenant data isolation, and admin tools
- CI/CD, preview environments, and feature flags
- Product analytics and growth experiment scaffolding
- A handoff doc, a runbook, and an optional retainer
◆ Stack
How we build it.
Next.js App Router, TypeScript end to end, Postgres via Supabase or Neon, Stripe for billing, Resend for transactional email, Vercel for hosting, PostHog for product analytics. Boring stack on purpose.

◆ Why Thinkmakr
We run a SaaS of our own. Socialmakr posts to six platforms with adaptive formatting, schedules across timezones, and handles billing. The patterns we use to operate it are the patterns we bring to your build.
◆ How we work
- No offshoring. The team that scopes the work ships the work.
- Your code, your repo, from day one. Full ownership at handoff.
- Fixed milestones and written proposals. No surprise invoices.
- Reviewable PRs. You can read every line before it ships.
- We tell you if we are the wrong fit and recommend who is.
◆ Receipts
Live products that prove the studio works.
The strongest argument we can make is the software we already ship.
◆ Common questions
Things people ask before they brief us.
How much does it cost to build a SaaS?
A SaaS engagement at Thinkmakr typically ranges from mid five figures for an MVP to low six figures for a full launch with billing, admin tools, and integrations. See /pricing for ranges.
How long does SaaS development take?
12 to 20 weeks from signed proposal to a live, billable product. The first three days produce a clickable prototype. The next 12 to 16 weeks are design, engineering, billing, and launch.
Do you handle billing and Stripe?
Yes. Subscriptions, trials, dunning, proration, and tax are part of every SaaS build. We default to Stripe Checkout and Customer Portal so the integration stays small.
Multi-tenant or single-tenant?
Multi-tenant by default. Row-level security in Postgres, plus tenant-aware APIs. Single-tenant only when compliance or large-enterprise requirements force it.
Will you stay on after launch?
Most clients keep us on a retainer for the first six months. After that you can take it in-house, switch to freelancers, or extend.
B2B SaaS or consumer SaaS?
Both. The patterns are similar; the surface area differs. We have shipped both. We will tell you which we think is the better business case during discovery.
◆ Pairs with
SaaS Development usually pairs with our Engineering service.
