Start this week
- Tell me your hours per week available, your city, and whether you know any dentists, dental-supply reps or dental labs.
- Check four Indian EMRs for two-way WhatsApp confirmations and price: Practo Ray, Eka Care, HealthPlix, DocPulse. If two of them bundle it at ≤₹1,000 a month, stop here.
- Call or visit 15 dental clinics. Ask: "How many patients didn't turn up last month? How does reception confirm tomorrow's list today? What software runs your diary?"
- Spike the WhatsApp Cloud API on a test number: one utility template with Confirm/Cancel buttons, a webhook for the reply, and a Google Calendar update.
- Check trademark and domain availability for the working name.
Checkpoints and kill gates
Decide in advance what counts as on track. Missing a checkpoint means changing the buyer or the offer, not adding features.
Day 14
~15 hrs/week
Cloud API spike done: a test clinic number sends a utility template, receives a button reply, and updates a Google Calendar event. Onboarding route (Tech Provider or partner) and its cost known.

If you miss it
If you can't onboard a clinic's own number without a platform fee above ₹500 a month, stop.
Day 45 (kill test)
~15 hrs/week
15 clinic conversations. 10 clinics paying for the hand-run pilot. Baseline no-show rate measured in ≥5.

One retry with physiotherapy or dermatology clinics in the same city. Miss twice: stop.

If you miss it
Stop. A reminder tool that can't show its number has nothing to sell.
Month 6
~15 hrs/week
$1k MRR (~35 clinics). Month-3 retention ≥75%. ≥1 trade partner sending clinics.

If you miss it
Stop adding features. A profitable $1.5–3k is the realistic outcome; decide if it's worth your hours.
Month 18

$3.5k (~15 hrs/week) or $5k (full-time)

Second city only if the first city's referral share is ≥40%.

If you miss it
Above target: hire one field-sales person for the $10k rung. $1k to target: run it for cash. Below $1k: shut it down.
Do
1.Test one wedge only: Indian dental clinics with 2–6 chairs, in one city, that run the diary on paper, Google Calendar or a basic EMR with no two-way WhatsApp
Target: 100% of year-1 revenue from dental clinics in one city
Why: Dental appointments are longer and worth more than a GP visit, so an empty chair hurts. One city lets you visit clinics in person.
2.Two-way WhatsApp confirmation: Confirm / Reschedule / Cancel buttons. Every reply updates the diary. A 9 a.m. "unconfirmed list" goes to reception to call.
Target: ≥70% of reminded patients reply
Why: Fresha's WhatsApp reminders are one-way (patients can't reply, verified). The reply is what turns a reminder into a filled chair.
3.Slot refill: when a patient cancels, offer the slot to a waitlist automatically, first to accept wins
Target: ≥30% of freed slots refilled by month 6
Why: Reminders alone cut no-shows by about a quarter (meta-analysis). Refill is the only feature that adds money beyond what every EMR ships.
4.Measure a 4-week baseline before switching on, then report monthly: no-show rate, slots refilled, estimated ₹ saved
Target: Median clinic's no-show rate down ≥25% (relative) by day 60
Why: Studies show ~21% → ~15% with reminders. If you can't show that in a clinic's own numbers, it cancels in month 3.
5.Sell a 30-day paid pilot before building: ₹999 setup, run by hand from the WhatsApp Business app and a shared sheet
Target: 10 paying clinics by day 45
Why: Proves the pain and the price before code. It's also the kill test.
6.Price flat, in rupees: Starter ₹1,499, Clinic ₹2,999, Multi-site ₹5,999 a month. Annual at 10× monthly. No free plan.
Target: Blended ≥₹2,500. ≥40% on annual by month 12.
Why: Practo Ray is reported at ₹999–3,999 for a whole practice suite. You can't charge more than the suite for one feature.
7.Connect straight to the WhatsApp Cloud API, on the clinic's own number (embedded signup as a Meta Tech Provider, or the cheapest partner route that allows it)
Target: Messaging + platform cost ≤12% of revenue
Why: Reselling a provider's ₹1,350–2,500/month platform wipes out the margin. The clinic's own number keeps trust and deliverability.
8.Google Calendar sync first. Add one EMR integration only when ≥5 paying clinics use the same EMR and it has an API.
Target: First EMR integration no earlier than month 6
Why: The original idea is "layered on existing calendars". Each EMR integration is permanent upkeep.
9.Distribution through the dental trade: dental-supply reps, dental labs, local Indian Dental Association branches, dentist WhatsApp groups. Referral: 1 free month per paying referral.
Target: ≥40% of new clinics from referral or trade partners by month 9
Why: Dentists buy what other dentists use. Cold ads to clinics are expensive and slow.
10.Automate operations: 20-minute self-serve onboarding, template library in English, Hindi and one regional language, no custom work
Target: ≤1 support hour per 10 clinics a month
Why: Keeps it workable at ~15 hrs/week and keeps margin ≥85%.
11.Privacy rails from day one: a data-processing agreement with each clinic, only name + phone + time + dentist stored, no clinical details in any message, delete 90 days after the appointment, record every opt-in
Target: Zero clinical data in messages. Zero incidents.
Why: The clinic is the data owner under India's DPDP Act; you're its processor. A leak ends you in a word-of-mouth market.
12.Recall reminders ("6 months since your cleaning") only as a paid add-on, after you've confirmed how Meta categorises them
Target: Recall cost passed through at cost + margin
Why: Recall is likely a marketing message (~₹1.09 each at AiSensy's list rate, ~8× a utility message). Unpriced, it can cost more than the plan.
Avoid
1.The idea as described: every channel, every vertical, every country
Why: Reminders are a checkbox in every booking and practice system. There's no single buyer, message or channel.
2.US healthcare
Why: Weave ($239M revenue in 2025, 39,625 locations, verified) owns the category. Open Dental sells confirmations for $25 a month with reminders free. HIPAA needs a BAA (Apptoto only signs one at $208+/month). Every texting number needs 10DLC registration.
3.Salons and spas
Why: Fresha, Vagaro, Booksy and Square include reminders. Fresha already sends WhatsApp reminders (verified). A salon won't pay for a second tool to do what its booking app does.
4.Brazil
Why: Capim gives Brazilian dentists free, unlimited WhatsApp reminders and confirmations (verified). Dozens of local tools sell the same thing. You'd also be selling in Portuguese.
5.Indonesia
Why: The reported WhatsApp utility rate there (~$0.025) is ~18× India's, and nothing about the local clinic market was verified.
6.Voice calls and IVR in v1
Why: Telephony, local numbers, call quality and cost. Patient-facing voice is a separate product.
7.SMS fallback in v1
Why: India needs DLT registration for every sender and template. Add it only if pilots show ≥20% of patients aren't on WhatsApp.
8.Reselling a WhatsApp provider's platform (AiSensy, Interakt, WATI) under your brand
Why: Their monthly fee is close to your price. You own no margin and no product.
9.Unofficial WhatsApp automation (WhatsApp Web bots, "unofficial API" services)
Why: The clinic's number gets banned, and it takes their patient history with it. One ban ends the relationship and the referral chain.
10.Marketing content inside utility templates (offers, "book your whitening")
Why: Meta can recategorise or pause templates, and the number's quality rating drops. Keep reminders strictly transactional.
11.Building an EMR, booking engine or billing
Why: That's what Practo Ray, Eka Care, HealthPlix and DocPulse do. You'd become their weakest competitor.
12.An "AI receptionist" chatbot in v1
Why: Clinics buying reminders want fewer no-shows, not a bot answering clinical questions. It adds liability and Meta-policy risk (unverified). Cliniko add-ons already sell this.
13.A free plan or lifetime deals
Why: Clinics that don't pay won't measure a baseline, and without the baseline the report can't prove anything.
14.Adding features or verticals when a checkpoint fails
Why: A miss means the pain isn't worth ₹1,500–3,000 a month to this buyer. The answer is to stop, not to add physios, salons and voice.
