Commercial solar EPC companies · Referral marketing

A factory owner trusts a plant he has stood beside more than a proposal he has read.

Referral marketing for a commercial solar EPC company is turning running plants, consultants, builders and bankers into a steady source of introductions to factory and campus owners. GullySales sets up the ask, a hosted-visit routine and a record of each introduction, within what each person's trade allows.

What referral marketing means

Referral marketing is asking an existing customer to recommend you to someone they know, usually with a reward for both sides. It differs from a loyalty scheme because it brings in a new customer rather than a repeat purchase. GullySales builds the ask and the reward into a point where a customer is already satisfied.

For commercial solar EPC companies

Where it usually goes wrong, and what we would do.

  • “A visit to a running plant closes more than a brochure”

    An owner who has watched an inverter room and spoken to the plant head who lives with it is moved by a different kind of proof. Most EPC companies never ask a customer to host.

  • “Advisers meet the buyer first”

    An energy consultant, a PEB builder or a banker is asked about solar before you are. If they have no reason to name you, they name whoever called last.

  • “Referrals are not tracked, so they are not thanked”

    A name comes up on a survey call, the engineer notes it nowhere, and the person who sent the buyer never hears what happened. The next introduction goes to someone else.

What we do

What we deliver for commercial solar EPC companies.

Every deliverable, what it covers for you, and the result it is there to produce. Nothing here is an extra.

  1. A hosted-visit routine for running plants

    A written ask to willing owners, a set of days, a briefing for the plant head and an agreement on what stays private.

    Result: A new buyer can visit a plant with its owner's blessing.

  2. A pack for consultants and builders

    A short note on what you take on, the roofs you handle and what you need from their client, with a tracking sheet for each introduction.

    Result: An adviser knows when to name you and what happens next.

  3. A referral record on every file

    A field on each enquiry for who sent the buyer, which plant they saw and what was said.

    Result: You can tell which introductions become orders.

  4. A thank-you routine

    A message and a short call to each source after an introduction, whatever the outcome, within what their trade allows.

    Result: The person who referred hears what became of it.

  5. A note for owners of installed plants

    A plain request to installed customers about neighbours in the same estate, sent with their performance summary.

    Result: Asking comes with something of value.

How the result is measured

  • Referrals received
  • Referral conversion rate
  • Cost per referred customer

Recorded as a baseline before work starts, so every later report has an honest comparison.

How referrals reach you

A factory owner will believe a neighbour's running plant before he believes your brochure.

The owner of a running plant
Ask at commissioning whether he would host a visit for a buyer in the same estate. Agree days, brief the plant head, and note what he wants kept private, such as bills and contract value.
The energy consultant or auditor
He writes the report that sets the question. Share your survey format and the roofs you handle, and agree in writing what is paid, if anything, and that the client is told.
The PEB builder or the roofing sheet supplier
He sees the shed before and after construction. Tell him your load checks and when a roof must be strengthened first, and record the project each time he names you.
The bank or NBFC relationship manager
He meets an owner ready to borrow. Give him your project details and the finance options you work with, and let the owner choose. Never route a buyer to a lender who pays you.
The industrial association
Offer a talk on reading the electricity bill, not a sales pitch. Members who learn something remember who taught them. Note each member who speaks to you and follow up the same day.
What never to do
Never share a customer's bills, roof drawings or contract value with a new buyer without his yes. An owner who finds his plant discussed with strangers will not host the next visit.

  • Rooftop EPC specialists for factories and industrial units
  • Warehouse, cold storage and logistics park rooftop installers
  • Campus installers for schools, colleges and hospitals

Not for

It is not the right fit if.

  • You want a guaranteed Google ranking or a guaranteed number of leads. Nobody honest can promise either.
  • You need enquiries by next week and have nobody to answer them.
  • You want posts and reach reported, not enquiries and orders.

How it works

From your first message to the first report.

No open-ended retainer. Every step gives you something in writing.

  1. 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.

  2. 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.

  3. 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.

  4. 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 reply time, a follow-up sequence, the page buyers land on or the handover between marketing and sales.

  5. 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.

  6. 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.

How the referral marketing work runs

  1. 1

    Understand your margin and customer relationship

    We agree what reward is genuinely sustainable and appropriate for your business and customer type.

  2. 2

    Audit existing informal referrals

    We check how much word of mouth already happens, to size expectations for the formal programme realistically.

  3. 3

    Design the offer and mechanism

    A specific reward and an easy sharing method are built and tested.

  4. 4

    Implement and promote

    The programme is surfaced at the right moments in your customer journey.

  5. 5

    Measure and adjust

    We track referrals and conversions, adjusting the reward or promotion if uptake is low.

Why us

Why owners pick GullySales over an agency.

  • Marketing and sales, as one job

    Most agencies stop at the enquiry. We also fix what happens after it: the reply, the follow-up, the quote and the CRM.

  • 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 office, and we say so

    Nagarbhavi, Bengaluru. We work across India by call and WhatsApp and travel when a session needs to be in person.

FAQ

Questions owners ask before they call.

Not here? More answers, or ask on WhatsApp.

Tell us what you need
Should we pay an energy consultant who sends us work?
Agree it in writing, tie it to a signed order and tell the client. A consultant whose client believes him independent but who takes a payment from the installer puts both of you at risk. Some consultants refuse on principle, so ask before you assume.
How do we ask a customer to host a visit without pestering?
Ask at commissioning, when the plant is working and the owner is pleased. Offer fixed days, offer to brief the plant head, and say what the visitor will see. Ask for a few visits only, and stop when the owner says enough.
How do we track who sent whom?
Put a field on the enquiry form and the survey sheet, and ask every buyer who told him about you. Record the answer even if it is a vague name. After a few months the same names come up, and those are the sources to look after.
Can a banker or an architect refer us?
Many do, in the interest of their own client. Give them your project details and let the buyer choose. Check what their employer or profession allows before offering anything, and prefer a clear thank-you and an update on the file.
Should we publish a rate per kWp on our website?
Publish the basis, not a bare rate. Say what is inside it: modules, inverters, structure, cabling, approvals and monitoring, and what is outside it. A buyer will compare numbers, so a rate without the scope invites a lower quote that leaves half the work out.
Do factory owners search online, or does everything come through consultants?
Both. Consultants and associations bring many introductions, but the plant head or the owner then searches your name, your projects and your reviews before a survey is agreed. If that search finds nothing, a good introduction goes cold.
How much does it cost?
There is no price list, because the work differs by business. The fee is scoped after we have read your brief and spoken to you, and put in writing before anything starts, split into our time, your media spend and production.
How long is the contract?
The term is agreed in writing after we have spoken, along with the fee and the reporting. It is never a default twelve months, and renewal is decided on the numbers against the baseline recorded at the start.
How soon will we see results?
It depends on the trade, the channel and what is already in place. After we have read your brief and spoken to you, we say what we would expect to move first and how it will be measured against the baseline. Nothing here is guaranteed.
Who will actually do the work?
The person you speak to before anything starts. We work from one office in Nagarbhavi, Bengaluru, with no account managers in between.
