B2B SaaS That Ships in Weeks, Not Months

Most founders we talk to have already spent $40K to $60K with a team that shipped a prototype, not a product. That's 6 months and $50K to learn the architecture was wrong and the scope was never agreed in writing.

We build production-ready B2B SaaS in 8 to 12 weeks for $10K to $40K: multi-tenant, API-first, with the architecture decisions that cost $100K+ to retrofit already made correctly before sprint one.

  • Multi-tenant architecture, SSO, RBAC, and Stripe billing built in from day one, not bolted on when you need to pitch enterprise

  • Working product in 8 to 12 weeks: not a wireframe, not a prototype, not a staging environment

  • You own the code and infrastructure outright, no vendor lock-in, no dependency on us to keep it running

  • Fixed price agreed before we write a line, no hourly billing, no cost surprises mid-project

Recognition

Sound familiar?

  • Offshore team shipped a working demo but it's not multi-tenant, has no SSO, and the codebase isn't something you can hand to a new team without a full rewrite?

  • Three months into a build and the scope keeps expanding because nothing was defined in writing before work started, and the original estimate is already gone?

In short

RaftLabs builds production-ready B2B SaaS products in 8 to 12 weeks for $10K to $40K. Every build includes multi-tenant architecture, SSO, RBAC, Stripe billing, and API-first design from day one, not bolted on later when retrofitting costs $100K or more. You own the code and infrastructure outright with no vendor lock-in. Most founders who came to RaftLabs after a cheap offshore build had already spent $40K to $60K and lost 6 months before the first working version.

Why B2B SaaS Development Matters

Average cost of in-house dev for basic B2B SaaS

Higher unit economics when built right the first time
~55%

You're Stuck Between Two Bad Options

  1. Hire in-house

    • 2 to 3 months to find the right developers.
    • $150K to $200K each per year.
    • Equity dilution if it's a co-founder.
    • 6+ months to ship the first version.
    • You've burned $225K before your first real user.
  2. Go cheap offshore

    • $10K to $15K sounds good until the code lands.
    • Wrong architecture.
    • No multi-tenancy.
    • Stripe integration that breaks in production.
    • 4 to 6 months of fixes later, you've spent $40K to $60K, you're 9 months behind, and the codebase is unusable at scale.
    • While you're deciding, your competitor shipped last month.

What You Actually Need

  1. Built From Real-World Experience

    We've built 50+ products and made the same architectural decisions you're about to face, across B2B SaaS, marketplaces, and creator platforms.

  2. You Don't Fund Our Learning Curve

    You're not paying us to experiment. You're paying for proven decisions, battle-tested patterns, and execution without trial and error.

  3. Predictable Pricing & Clear Timelines.

    Fixed-price engagements between $10K and $40K, depending on scope. In 8 to 12 weeks, you get a production-ready MVP that you fully own.

  4. No Surprises. No Lock-In.

    No scope creep. No hidden dependencies. You take the code, documentation, and infrastructure and hire in-house whenever you're ready.

Problems B2B SaaS founders bring to us

  1. 01
    Problem

    Feature backlog stalls because tech debt from the first build now blocks every new sprint

    Solution

    Most early SaaS builds optimise for speed, not architecture. The shortcuts that got you to demo day, single-tenant data models, hardcoded config, no abstraction on the billing layer, become the ceiling that stops you growing. According to Stripe's Developer Coefficient report (surveying 300+ engineering teams), developers spend an average of 33% of their time dealing with technical debt and bad code rather than building new features. When a third of every sprint disappears into maintenance before a single backlog item is touched, the product falls behind while your competitors move. A structural refactor that resolves the core debt, rather than patches on top of patches, restores sprint velocity and lets the team ship what's actually in the backlog.

  2. 02
    Problem

    Multi-tenant architecture wasn't built in from the start, and every enterprise prospect asks whether their data is isolated

    Solution

    Multi-tenancy retrofitted after a single-tenant build is almost always a full rebuild. The data model is wrong, the row-level security is missing, the schema isolation doesn't exist. When your first enterprise customer asks "is our data isolated from your other customers?" and the honest answer is "not yet," you either lose the deal or take on the technical debt. Multi-tenant architecture designed from sprint one, separate schemas or row-level security, per-tenant configuration, admin isolation, gets the right answer for zero extra cost. Retrofitting it later costs $50K to $100K and three months.

  3. 03
    Problem

    No integration marketplace means every enterprise deal requires a custom one-off build that your team can't sustain

    Solution

    40% of B2B SaaS customers require API access or integration with tools they already use. When the API was designed incrementally, endpoint added when a customer requested it, authentication changed when a security issue arose, it becomes inconsistent and poorly documented. Enterprise integration teams spend days on support calls instead of shipping. An API-first architecture with a clean, documented integration surface means your largest customers can integrate without a support engagement. An integration marketplace lets you build once and offer it to everyone.

  4. 04
    Problem

    No SaaS metrics instrumentation means you can't see churn signals, expansion revenue, or where the product is actually breaking

    Solution

    Billing infrastructure looks simple until you have customers on annual plans, mid-cycle upgrades, usage-based overages, and churn at billing renewal. Stripe's API handles the mechanics, but the billing logic, proration, dunning, upgrade and downgrade workflows, invoice generation, requires careful implementation. Billing bugs in production are expensive: lost revenue, customer trust damage, and manual reconciliation by your finance team. Billing architecture built for your pricing model from the start handles the edge cases before customers encounter them. Instrumented metrics on top means you see a churn signal three weeks before the customer cancels.

FAQs

Most take 8 to 12 weeks from kickoff. The range comes down to two things: integration complexity (SSO, payments, third-party APIs) and how fast your team can make design decisions. If scope is locked and stakeholders are responsive on week one, we stay on the low end.

Design, architecture, full development, AWS deployment, QA, and documentation. Not included: third-party service fees (Stripe, SendGrid, auth providers), ongoing hosting costs, or post-launch iteration. Those are separate line items we walk you through before you sign.

You do. Entirely. Every line. We don't retain IP, licensing rights, or access after the engagement ends. You can take the codebase to a new team tomorrow and they'll be able to work with it, because we document it.

Yes, and we encourage it. We build on standard, well-documented stacks (React/Next.js, Node.js, AWS) that any senior developer can pick up. We'll do a proper handover, and if you want us on retainer while you hire, that's available.

Our team is based in India. "Offshore" gets a bad reputation because most offshore work is executed poorly: no architecture decisions, no product thinking, no production-grade standards. We compete on quality, not on being cheapest. If you've received $15K offshore work before, look at the codebase. If multi-tenancy was bolted on later or Stripe breaks in production, that's the difference.
