## 4. Client Proposal
Hi there,
Thanks for walking me through the clinic's needs. Here's how I'd get your booking app live.
**Project understanding:** You want patients to book and pay from their phones, with every appointment landing straight in your Google Calendar, so nobody retypes bookings by hand.
**Scope:**
- Mobile-friendly booking form with live availability
- Booking engine with double-booking protection
- Two-way Google Calendar sync
- Online payment at checkout
- Simple admin list of all bookings
- Full mobile testing and launch support
**Timeline:** About 4 weeks, comfortably inside your 6-week target.
**Investment:** $6,969.24 in total, including an 8% contingency for surprises.
**Assumptions & exclusions:** One payment provider (to be confirmed), one clinic location, hosting and payment fees billed to you directly. Native iOS/Android apps are not included.
**Next step:** Answer the three open questions (practitioners, cancellations, standalone or embedded) and I'll send the agreement the same day.
Looking forward to it!
Alex
## 5. If They Push Back on Price
Hi again, totally fair to ask. The $6,969.24 covers everything we scoped, and I'd rather not cut corners on it. One option: we launch without online payments first and add them as Phase 2 later. That saves $1,597.32 now, bringing Phase 1 to $5,371.92, and patients can still book and sync with your calendar from day one. Want me to send the Phase 1 version?
