Why pick an experienced B2B web development vendor over a freelance team
A single developer can build a basic site, but B2B web apps need compliance, integrations, and multi-role logic.
B2B web applications handle sensitive data, complex user permissions, and integration with enterprise systems like Salesforce, NetSuite, or QuickBooks. A freelance developer lacks the team redundancy, security review, and project management discipline required for a platform that 500+ employees will depend on daily.
IRPR brings a team of senior engineers, a QA specialist, and a project manager to every engagement. We have shipped B2B portals for logistics firms with 2000+ active suppliers and healthcare platforms that handle PHI. Our fixed price model means you know the budget before the first line of code is written.
Freelancer vs IRPR: the real difference
Choosing between a freelancer and an experienced B2B web development vendor impacts your timeline, compliance, and long-term maintenance.
Freelancers often work alone, have limited availability for support, and may not have experience with enterprise-grade security or multi-tenant architecture. Their hourly billing model can lead to scope creep that blows your budget by 30-50%.
IRPR offers a dedicated team of 3-5 senior engineers, a QA specialist, and a project manager. We use code reviews, automated testing, and CI/CD pipelines to keep quality consistent. Our fixed price is set after the Roadmap phase, so there are no surprises.
- Solo developer with limited backup
- Hourly billing with risk of overrun
- No dedicated QA engineer
- No compliance review (HIPAA, SOC 2)
- Code not documented for handoff
- Limited availability for urgent fixes
- Team of 3-5 senior engineers + PM + QA
- Fixed price after Roadmap phase
- Dedicated QA on every project
- Compliance built in (HIPAA, PCI, SOC 2)
- Full documentation and source code delivered
- SLA with 4-hour response time
How we deliver B2B web apps for enterprise buyers
Our process moves from idea to production in four distinct phases.
Every project starts with a 1-week Discovery phase where we interview stakeholders, map workflows, and identify integrations. We then produce a Roadmap that defines scope, timeline, and fixed price. This takes 1-2 weeks and costs $5K-$10K, credited toward the build.
The Product phase is 8-12 weeks of weekly sprints. You see a working build every week. We deploy to staging, run automated tests, and perform security checks. Release includes production deployment, CI/CD pipeline, and a 30-day warranty for bug fixes.
What ships with every B2B web development project
Every engagement includes the artifacts and infrastructure your team needs to operate independently.
We deliver source code to your GitHub repository with full commit history. The code is documented and follows your coding standards. We also provide a deployment guide and runbook for your DevOps team.
All projects ship with a CI/CD pipeline configured on GitHub Actions, automated testing with Jest and Cypress, error tracking via Sentry, and uptime monitoring via Datadog. You own everything from day one.
