API Integration by the Numbers
Our track record speaks for itself.
We have shipped over 200 API integrations across 50 countries. Our average integration goes live in 10-12 weeks from kickoff.
Clients using our integrations report 99.9% uptime and 40% reduction in manual data entry.
The Difference Between Us and Generic Dev Shops
Not all integration projects succeed. Here's why ours do.
Generic development shops often bill by the hour and deliver incomplete integrations. They leave you with no documentation, no ownership, and no compliance.
IRPR delivers a complete package: fixed price, full code ownership, compliance built-in, and a clear timeline. Your integration works from day one.
- Billing by the hour with no cap
- No API documentation delivered
- Unclear ownership of code
- No compliance expertise
- Scope creep without change control
- Long timelines with no fixed end date
- Fixed price agreed in week 2
- Full API documentation in Postman or Swagger
- You own all source code
- Built to HIPAA, PCI-DSS, SOC 2 standards
- Scope changes managed with transparent change orders
- 8-12 week timeline for most integrations
Our 4-Phase Integration Process
How we take your integration from idea to production.
We follow a structured approach to ensure every integration is built on time and on budget. Each phase ends with a clear deliverable.
Our process has been refined over 200+ projects and fits into a standard 8-12 week timeline.
What You Get With Every Integration Project
