calendar booking implementation cost fixed price agency quote in 2026

Who You Actually Need

Most startups don't need a 10-person team on day one. You need a product-minded agency that ships MVPs in weeks, hands you GitHub access, and knows App Store rules.

• MVP agency: fixed scope, 3–6 week delivery, milestone payments
• Freelancer: cheaper upfront, higher management overhead
• In-house hire: right after product-market fit, not before
• Offshore team: verify timezone overlap and English in code reviews

Evaluation Checklist (Score 1–5 Each)

Interview three agencies minimum. Use the same PRD for apples-to-apples quotes.

• Shipped apps in your category (App Store links, not mockups)
• Fixed-price contract with milestone deliverables
• Custom design—not template UI
• Post-launch warranty (30-day crash fixes)
• Clear IP ownership and repo handoff
• References you can actually call

Questions to Ask on the First Call

Skip agencies that can't answer these without a sales deck.

• What's included in your $3,460 package and what's excluded?
• Who submits to App Store and handles rejections?
• What stack do you default to and why?
• How do you handle scope changes mid-sprint?
• What happens if we need a v1.1 two weeks after launch?

Contract Must-Haves

A Statement of Work beats a vague proposal every time.

• Feature list with acceptance criteria
• Payment tied to TestFlight / staging milestones
• Source code in your GitHub org before final payment
• Warranty period and hourly rate for out-of-scope work
