How to onboard plumbers without losing them in week one
Plumbers move between many small jobs in a day, buy from whichever counter is nearest and have little patience for registration forms. They join a program when the first reward is immediate and the steps are explained in their own language, usually by someone they already trust at the counter.
To onboard plumbers, recruit them through plumbing counters, plumber meets and product packaging, let the first QR scan on WhatsApp or the app be the sign-up with only a mobile number, pay that first reward by UPI immediately, and ask for KYC only when payout requires it. Support them by voice in their language, aim for a second scan within 14 days, and measure active plumbers by source rather than registrations.
Where plumbers are found
| Source | Approach | Watch out for |
|---|---|---|
| Plumbing counters and sub-dealers | Counter staff introduce plumbers and help with the first scan | Reward retailers per active plumber, not per registration |
| Plumber meets | Demo scan with an instant reward during the meet | Follow up within a week with a second-scan offer |
| Packaging | QR on pipe lengths and fitting packs with a clear reward line | Reward line must be visible and in the local language |
| Plumbing contractors | Contractors bring their teams onto the program | Ensure rewards reach the plumber who fitted, as agreed |
| Plumber referrals | Active plumbers invite peers and helpers | Pay after the new plumber's first valid scans |
First scan as sign-up
Do not make plumbers fill a form before they see value. A plumber scans the QR on a fitting pack with WhatsApp or the app, enters his mobile number and name, and sees the reward. Collect UPI details when the first payout is due and identity documents only when compliance requires them. Fewer fields at the start means more plumbers reach the reward.

Plumber meets that convert
A meet is only as good as what happens in the following week. Run a demo scan with a real fitting pack during the meet so every attendee sees money land on his phone. Note who scanned. Within seven days, send each attendee a mix offer in his language and ask the nearest counter to remind those who have not scanned again. Invite active plumbers from earlier meets to speak; a peer explaining how he gets paid is more convincing than a brand presentation.
WhatsApp first, app for regulars
WhatsApp needs no download and covers scanning, balance and scheme questions. Frequent scanners value an app for history, tiers and the catalogue. Start everyone on WhatsApp and invite regulars to the app. If you already have a brand app, the loyalty features can run inside it through an SDK.
Language, voice and trust
Many plumbers prefer to ask a question by voice. Support in Hindi, Marathi, Tamil, Telugu, Bengali or Gujarati, as your markets need, is essential. Trust also comes from speed: if a plumber's first payout fails because of a wrong UPI ID, fix it the same day.
Make the counter your onboarding partner
The plumbing counter sees plumbers every day. Give retailers a simple role: help with the first scan, and earn a small reward when a plumber they introduced becomes active. Show the retailer which of his plumbers are active. This turns the counter into a recruiter rather than a coupon collector.
Plumbers who work across brands
Plumbers rarely commit to one brand on day one. They fit what the job or the house owner needs. Expect gradual change: as your rewards arrive faster and your support is easier, more of their jobs shift to you. Show each plumber his scan history by product family so he sees what he earns from you. Helpers working under a senior plumber are worth onboarding too, because they often do the fitting and become plumbers in their own right.
Train the people who onboard
Sales officers, counter staff and support agents should all be able to do a demo scan, explain the reward card in one sentence, and fix a wrong UPI ID on the spot. A demo fitting pack at each counter and a one-page script do more than posters. Review sign-ups by sales officer each month so the people who onboard well can teach the others.
Activation metrics
Track: the share of registrations with a first valid scan; the share with a second scan within 14 days; 30-day active plumbers; product families per plumber; and all of these by source. Drop or redesign sources that bring sign-ups without scans. The plumber loyalty program guide explains the program design these numbers depend on.
