Senior B2B Web Development FirmB2B Web
Seniors only. Fixed price. 12 weeks to MVP. We build B2B web apps that scale.
IRPR builds B2B web applications for companies that demand senior-level engineering. We use React, Next.js, Node.js, PostgreSQL, and AWS to ship production-ready code. Every project starts with a 2-week Roadmap phase that locks the scope and price.
A typical B2B web MVP ships in 12 weeks with a fixed price between $80K and $250K. We handle compliance too - SOC 2 for SaaS, HIPAA for healthcare, PCI-DSS for fintech. You get full ownership of the source code and infrastructure.
Our clients are CTOs scaling a B2B platform who need experienced engineers, product managers launching a marketplace who want a predictable timeline, founders with funded startups who need a reliable build partner, and enterprise IT directors replacing legacy portals.

What a senior B2B web development firm delivers
B2B web applications built by senior engineers ship faster, have fewer bugs, and scale without rewrites.
IRPR only hires senior engineers with 8+ years of production experience. Every developer has shipped at least 10 production apps. We do not use junior or mid-level developers on client projects. This means your B2B web app is built by people who have seen and solved enterprise-scale problems before.
Our team uses code review, automated testing, and CI/CD pipelines from day one. We set up Sentry error tracking and Datadog monitoring before launch. The result: 99.9% uptime across all projects and an average of zero critical bugs reported in the first 90 days.
Generic shop vs. senior B2B web development firm
The difference is experience, process, and accountability. Here is how IRPR compares to a generic development shop.
Generic development shops often assign junior engineers to B2B projects. They hide technical debt in the first build, then charge you to fix it later. They bill hourly and have no incentive to ship fast.
IRPR assigns senior engineers from day one. We build for maintainability and scalability. We quote a fixed price after a 2-week Roadmap phase. If scope changes, we adjust the price before we write new code. No surprises.
- Assigns junior engineers to your project
- Charges hourly with no cap
- No compliance expertise
- Does not document architecture
- Uses outdated tools like jQuery or PHP
- Keeps IP unless you pay extra
- Senior engineers only, 8+ years each
- Fixed price after 2-week Roadmap phase
- HIPAA, PCI-DSS, SOC 2 compliant builds
- Full architecture documentation included
- Modern stack: React, Next.js, Node.js, PostgreSQL
- You own 100% of the code and IP
Our process for B2B web development
Every senior B2B web development engagement follows a 4-phase process designed for speed and quality.
Phase 1 is Discovery. We spend 1-2 days understanding your users, your data, and your business rules. We map out the core workflows and identify integrations. Phase 2 is the Roadmap. In 2 weeks we produce a detailed spec, a fixed price quote, and a timeline.
Phase 3 is the Build. Senior engineers start coding immediately. You see working software every 2 weeks in sprint reviews. Phase 4 is Launch. We deploy to production, set up monitoring, and hand over the source code and documentation.
What ships with your B2B web app
Every project delivers a complete, production-ready package. Here is what you get by default.
You get the full source code in your private GitHub or GitLab repo. We set up CI/CD with GitHub Actions or CircleCI, automated tests with Jest and Cypress, and monitoring with Sentry and Datadog. All infrastructure code is included as Terraform or Pulumi scripts.
We also provide architecture documentation, API documentation (auto-generated with Swagger or TypeSpec), and a runbook for your team. Every project includes a 30-day post-launch support period.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or CircleCI
- Automated tests: Jest for unit, Cypress for e2e
- Sentry error tracking and Datadog monitoring
- Terraform or Pulumi infrastructure scripts
- Architecture documentation (draw.io / Miro)
- API docs (Swagger / OpenAPI 3.0)
- User analytics setup (Mixpanel or PostHog)
- 30-day post-launch support and knowledge transfer

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. If you add features, we quote that too before writing code.
Senior engineers only
IRPR does not hire junior or mid-level developers. Every engineer has 8+ years of production experience and has shipped at least 10 apps. You get people who have already solved the problems you are facing.
12-week MVP delivery
From Roadmap sign-off to production launch, most B2B web MVPs ship in 12 weeks. We have done it for 200+ products. The timeline is locked in the fixed price quote.
Full code ownership
You own 100% of the source code, infrastructure scripts, and documentation. IRPR retains no IP. Your code is in your repo from day one.
No offshore teams
All engineering is done by IRPR employees in North America and Europe. We do not subcontract to offshore agencies. You talk directly to the people building your software.
99.9% uptime SLA
Every production deployment includes monitoring, alerting, and a runbook. We guarantee 99.9% uptime on the infrastructure we manage. In 200+ projects, we have never missed this SLA.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
