E-commerce · Smart Home & Security
Before anyone puts a lock on their front door, they want to know what happens when the battery dies.
A lock is bought for the door, the family and the worst night of the year. The buyer's first thought is the failure case: a flat battery, a dead app, a guest at the door, a fingerprint that will not read. Whether the lock fits the door at all is the second thought.
Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.
In one paragraph
Smart locks are door locks opened by fingerprint, PIN, card, app or key, fitted to a wooden, metal or glass door, and sold online with or without installation. GullySales works on the door-fit information, the failure and battery answers buyers look for, and the installation booking that turns an enquiry into a fitted lock.
So the page is read slowly, and a missing answer is taken as a bad answer. The sale often ends with a visit by someone to measure the door.
Last updated 7 Oct 2026. Product, labelling and advertising rules for smart home & security 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 smart locks online.
- Brands selling fingerprint and digital door locks for homes and rented flats
- Sellers of smart padlocks and cabinet locks for offices and PGs
- Dealers who supply and fit, and want their website to bring site visits
- Builders' suppliers who sell locks in bulk for a project and in singles online
Not for
It is not the right fit if.
- A seller who has no installation route and no clear policy for a lock that does not fit the door
- Anyone who wants a lock described as burglar-proof or unbreakable
How buyers choose
What decides the sale of smart locks.
Door type, thickness and handing
Wood, metal, glass or a UPVC frame, the thickness in millimetres and whether the door opens inwards or outwards, left or right. A wrong measurement is a wasted trip.
Ways to open the door and the manual key
Fingerprint, PIN, RFID card, app, mechanical key. The buyer looks for whether a key is still included and whether the PIN can be set for a guest and removed.
Battery, warning and emergency power
What kind of cells, what warning the lock gives, and how to open a door with a dead battery, such as a power bank terminal on the outside.
Installation and the warranty
Who fits it, whether the visit is free and whether drilling is needed, and what the warranty covers once the door has been cut for the lock.
Where sales are lost
What usually goes wrong when you sell smart locks online.
In the words sellers use on the first call.
“We get an order and then find the lock does not fit”
A glass door or an unusually thin one needs a different lock. The visit to the buyer's home was a loss, and the review calls the lock useless.
“People enquire and wait for an installer”
A buyer who cannot see a date or a person to fit the lock orders from a shop nearby.
“Landlords and tenants both ask, and we have one answer”
A tenant wants a lock that comes off without damaging the door, and a family wants a permanent one. The page talks to neither.
The scope
The work we would propose for smart locks.
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 with you before it goes in the scope.
- A door-fit check before the orderA short form that asks door material, thickness and opening direction and says whether the lock suits, before payment or a site visit.
- Installation bookingPages and a Google Business Profile for each city where you or a partner fit locks, with a booking step that shows the available day.
- Answers to the failure questionsA page on a flat battery, a failed fingerprint, a lost card and a power cut, written plainly and placed near the price.
- Search by door and needPages for what people type: a fingerprint lock for a main door, a lock for a glass door, a digital lock for a rental flat.
- Dealer and builder enquiriesA page for bulk and project orders that asks for the number of doors and the door type, and routes the enquiry to a person who can quote.
What we do
What you get for smart locks.
Each deliverable and what it is there to change.
A door-measurement guide
A diagram showing where to measure thickness and which way the door opens, with a photograph option for a buyer who is unsure.
A what-if page
A dead battery, a lost phone, a guest staying a weekend and a power failure, each answered in two lines.
An installation page by city
Who fits, what the visit includes, what happens if the door cannot take the lock and how a booking is made.
A rental flat page
Locks that fit with no cutting, how to restore the door, and what to ask a landlord, for tenants who want a smart lock.

How it works
From your first message to the first piece of work.
No open-ended retainer. Every step gives you something in writing.
First
Your brief
You tell us what you need in a few short steps: your business, what you want, where enquiries come from and how they are handled.
After the brief
A conversation and a written scope
We read it, then talk with whoever handles your enquiries. If you want our help, the scope, the fee and the reporting come in writing, and nothing starts before you have read them.
Before work starts
Baseline recorded
The numbers this work is meant to move, such as enquiries, quotations, orders, visits or renewals, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
The fix we agreed to start with is put in place and measured against the baseline, whether that is a reply, a follow-up, a page, a listing or the handover between marketing and sales.
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 we talk.
None of it has to be tidy. We read what you have.
- Your models and the door types each fits
- Installation partners by city and their visit terms
- Enquiries lost after a door-fit problem
- Your warranty terms in writing
- Questions customers ask by phone before ordering
Selling in India and abroad
Selling smart locks 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.
Door standards differ
Door thicknesses, mortise sizes and handles vary by country, and a lock built for Indian doors may not fit. Look at the markets you already ship to before listing.
Installation as the barrier
A lock bought abroad needs fitting by someone who stands behind it. Without a partner there, sell to NRI buyers for a home in India, or through a local distributor.

Why owners pick GullySales over an agency.

The person on the first call does the work
No account managers in between. You are never handed to someone you have not met.
A baseline before anything starts
Your numbers are written down on day one, so every later report compares against something honest.
The fee in writing, split three ways
Our time, your media spend and production on separate lines. You always see what goes to us.
No guarantees we cannot keep
The term is agreed in writing and never a default twelve months. We never promise a ranking or a lead count, because nobody controls those.

One fix, scoped
Start with the fix that matters most, such as reply time or follow-up. The fee is in writing before anything starts.
Option 3
An ongoing programme
We run the work, report against the baseline, and you renew on the numbers. The term and the reporting are agreed in writing first.
Option 4
Guidance for your own team or agency
We plan, brief and check the work of your in-house team or current agency, instead of replacing them.
