How IRPR Differs from Other B2B Portal Vendors
Most agencies bill hourly and deliver late. IRPR gives you a fixed price and a firm timeline.
We start with a 2-week Roadmap phase where we define the full scope, tech stack, and price. You get a fixed quote before any development begins. No hourly billing, no surprise invoices.
Our senior engineers work directly with your team. We use GitHub for code, Slack for communication, and Linear for task tracking. You see progress every week.
- Hourly billing with no cap
- Junior developers on your project
- No compliance expertise
- Deliverables slip by weeks
- No post-launch support plan
- Code ownership unclear
- Fixed price from Roadmap phase
- Senior engineers only (8+ years)
- HIPAA, PCI-DSS, SOC 2 built in
- 98% on-time delivery rate
- 12 months of maintenance included
- Full code ownership, no lock-in
Our B2B Portal Development Process
We follow a 4-phase process that takes you from idea to live portal in 12-14 weeks.
Every project starts with a discovery call where we learn about your buyers, suppliers, and workflows. Then we move into the Roadmap phase where we define the MVP scope and give you a fixed price.
After you approve the Roadmap, we build the portal in 8-10 weeks. We deploy to AWS or GCP with CI/CD pipelines, Sentry error tracking, and automated backups.
What Ships with Every B2B Portal
Every portal includes these deliverables by default. No hidden costs or add-ons.
We believe in full transparency. You own everything we build, and we provide all the tools you need to run the portal after launch.
Our standard package includes source code, infrastructure as code, monitoring, and documentation. You can take the portal to any other team after we finish.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- Infrastructure as code with Terraform on AWS
- PostgreSQL database with automated backups
- Role-based access control for buyers and suppliers
- Stripe integration for payment processing
- API documentation with Swagger
- 12 months of maintenance and bug fixes
- Full ownership with no licensing fees
