E-commerce · Water Purification
The buyer wants to be told which purifier suits their water, and we sell without asking.
The purifier is the product the buyer has the least information about. They do not know the TDS of their water, whether it is hard, or whether a borewell, a tanker or a municipal line feeds the house. So they ask the seller, and a seller who does not ask back sells the wrong machine.
A 90-minute audit call and a written, scored report. Turnaround, reporting and term are agreed in writing after the audit.
In one paragraph
A water purifier is a countertop or wall-mounted machine that treats household tap or borewell water using RO, UV, UF or a combination, installed by a technician and kept going with cartridges and a yearly service. GullySales works on how your listings match the machine to the buyer's water, show installation and service before payment, and turn each sale into cartridge and service-contract orders.
Then there is the fitting. Wall space, a power point, a tap with pressure, a drain for the reject water. A purifier that arrives without a plan for any of these is the one that gets the angry review.
Last updated 7 Oct 2026. Product, labelling and advertising rules for water purification differ by product and change. We describe them in general terms, so check the current position with your own adviser or the regulator before you publish a claim.
Who it is for
This is written for you if you sell water purifiers online.
- Brands with RO, UV and UF purifiers selling on marketplaces and through dealers
- Dealers with technicians who fit and service machines in their city
- Sellers of purifiers for borewell and tanker water in areas with hard or salty supply
- Sellers of commercial purifiers for offices, shops and clinics
Not for
It is not the right fit if.
- A seller who recommends a type of purifier without asking where the water comes from
- A seller with no technician in the buyer's city and no plan for one
How buyers choose
What decides the sale of water purifiers.
Water source and the first question
Borewell, tanker, municipal supply or a sump. The buyer who knows their source is half decided, and one who does not asks the seller to decide.
The purification stages and what each is for
RO plus UV, RO plus UF, with mineral additions. Buyers compare the stages as a feature list, then look at reviews to find out which stage matters for them.
Storage, flow rate and daily use
A family of six that fills many bottles and a flat that fills two need different tank sizes and different flow rates.
Reject water
The buyer who has heard that RO wastes water asks how much, where it drains and whether it can be used. A page that skips the question is read as avoiding it.
Where sales are lost
What usually goes wrong when you sell water purifiers online.
In the words sellers use on the first call.
“Customers say the water tastes flat or salty after a month”
A filter past its life or a wrong membrane for the water gives either result. The buyer was never told when to service the machine, so the review blames the product.
“They ask for a free demo in their home”
Dealers who give them win the sale. Online sellers have no answer, and a hard-water buyer wants someone to test the TDS in front of them.
“Installation takes ages and the product sits in a box”
The buyer paid, the box is in the hall and no technician has called. The review that follows is about service, but it lowers the page's rating.
The scope
The work we would propose for water purifiers.
Measured on purchases, conversion rate, cost to win a customer, average order value and repeat purchases. Anything here that needs a platform or tool we have not used with you is confirmed in the audit before it goes in the scope.
- A water-source chooserA short question set that asks the water source, the area and the family size, and returns one or two purifiers with the reason.
- City pages for service areasA page for each city or locality you service, with the machines you fit there and how a home demonstration is booked.
- Listings that explain the stagesA stage-by-stage graphic and a note on reject water, flow rate and tank size in the images and bullets on each listing.
- Service contract renewalsReminders to owners before the service is due, and a simple route to renew the annual contract, sent by WhatsApp or email with consent.
Installation booked at checkout
The fitting date and the technician's contact collected at the time of order, with a message to the buyer once the fitter is assigned.
What we do
What you get for water purifiers.
Each deliverable and what it is there to change.
A water-source guide for each purifier type
A page matching borewell, tanker and municipal water to RO, UV and UF models in your range.
A stage-by-stage graphic
The same simple picture of each stage, used on every listing, so a buyer comparing your models sees consistent information.
An installation tracker message set
A short run of messages that tell the buyer the fitter has been assigned, what to prepare and who to call.
A renewal reminder sequence
Messages to owners before the filter or contract is due, with a link to renew or book the service.
How the result is measured
- Purchases
- Conversion rate
- Customer acquisition cost
- Return rate
- Installation booked per order
- Service contract renewals
Recorded as a baseline before work starts, so every later report has an honest comparison.
How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Free audit call
90 minutes with whoever handles your enquiries: how they arrive, how fast they are answered, where they are lost.
After the call
Written, scored report
Six areas scored, fixes ranked by return and cost. If you want our help, the scope, the fee and the reporting come with it, in writing.
Before work starts
Baseline recorded
Enquiries by source, reply time, conversion and cost per order, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
Usually the cheapest one on the report: reply time, a follow-up sequence or the marketing-to-sales handover.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
What we need from you
What to have ready before the audit call.
None of it has to be tidy. We read what you have.
- Your purifier range with the technology and tank size of each
- The cities you install in and the technician capacity there
- Your service contract terms and renewal rate, if you track it
- Reviews and calls about taste, service delays or running cost
- Water test results you already hold for your main cities
Selling in India and abroad
Selling water purifiers beyond your own market.
Where you sell decides sizes, units, seasons and returns. We work from Bengaluru and have no overseas office, so for a new country we start from your own sales and the platforms you already use.
Few buyers for a fitted machine
A purifier needs a fitter and a service, so selling a complete machine abroad is difficult. Countries with a large Indian community and a partner who can install and service it are the place to look first.
Rules on water claims
What you may say about removing contaminants varies by country and is regulated more tightly in some. Your adviser confirms the wording before you list abroad.
