Headless Commerce Project EstimationProject Estimation
Get a fixed price in 2 weeks. Senior engineers deliver your MVP in 8-12 weeks.
IRPR builds headless commerce storefronts and backends using Next.js, Vue Storefront, Shopify Hydrogen, and Contentful. We handle everything from API integration (Stripe, Klaviyo, NetSuite) to hosting on Vercel or AWS Lambda.
Every project starts with a 2-week Roadmap phase that produces a fixed price estimate. MVPs are built in 8-12 weeks and range from $80K to $250K depending on feature set and compliance needs (PCI-DSS, GDPR).
We work with ecommerce directors who need a fast, predictable launch; CTOs at DTC brands migrating from monolithic platforms; enterprise retailers facing complex integrations; and venture-backed startups building custom storefronts from scratch.

Headless Commerce Project Cost & Timeline Data
Our estimates are grounded in 200+ real deliveries across 50 countries.
The average headless commerce project at IRPR costs between $80,000 and $250,000. Timeline from kickoff to launch is 8-12 weeks for a full MVP, including all integrations, content model, and checkout.
We track every project's actual hours vs. estimate. Our on-time delivery rate is 98%. When scope changes, we adjust the fixed price — not the deadline — so you never face surprise delays.
How Our Estimation Differs from Typical Agencies
Generic agencies estimate hourly. We give you a fixed price with a scope breakdown.
Most agencies give a vague ballpark and then bill by the hour when scope creep hits. That leads to cost overruns and timeline extensions — exactly what you want to avoid in a headless commerce project.
IRPR's approach is different: we spend 2 weeks in a Roadmap phase to define every feature, integration, and edge case. You get a fixed price and a clear delivery schedule before any code is written.
- Hourly billing with no ceiling
- Scope defined after starting
- Junior devs on your project
- No fixed delivery date
- Unexpected change orders
- Code ownership unclear
- Fixed price from day 1
- Scope detailed in a 2-week Roadmap
- Senior developers only
- 8-12 week delivery guarantee
- Change requests adjust price, not deadline
- Full code ownership transferred
Our 4-Phase Estimation and Delivery Process
From discovery to production, every project follows a structured path.
We break your headless commerce project into four clear phases. Each phase ends with a milestone that unlocks the next step.
This approach has been used for over 200 projects — it prevents waste and keeps your budget on track.
What Ships With Every Headless Commerce Project
Our standard delivery includes everything you need to operate and scale.
Every estimate includes a detailed delivery plan. You never wonder what you're getting or when it will arrive.
Below is the default checklist. Additional items (like advanced search or multivendor support) are defined in the Roadmap and priced accordingly.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline via GitHub Actions
- Sentry error tracking set up
- Performance testing report (Lighthouse 90+)
- PCI-DSS compliance checklist completed
- Stripe/Braintree/PayPal integration
- Admin dashboard (product, order, user management)
- SEO metadata per product page (Open Graph, structured data)
- User documentation for content editors
- 30-day post-launch with priority support

Why teams hire us.
Fixed Price, Not Hourly
Every headless commerce project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. If requirements change, we adjust the price — never your timeline.
Senior Engineers Only
We don't staff projects with juniors. Every engineer at IRPR has 5+ years of experience and has shipped at least 20 commercial projects. You talk directly to the person building your storefront.
8-12 Week MVPs
We ship a usable headless commerce product in 8-12 weeks. This includes integrations, content model, admin dashboard, and checkout. 98% of our MVPs launch on the planned date.
PCI-DSS Compliance Built In
We handle card data according to SAQ A-EP requirements. Stripe vaults payment info, and we never store raw card numbers. Compliance is part of the delivery, not an afterthought.
Full Code Ownership
All source code, CI/CD configs, and infrastructure-as-code belong to you. No proprietary licensing, no vendor lock-in. We hand over repositories and access on day 1 of the build.
Async-First Collaboration
Our team works across 4 time zones with daily overlap. You get a Slack channel, weekly sprint reviews, and a live demo environment. No required in-person meetings, no 24-hour response delays.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
