B2B SaaS startups · WhatsApp marketing

Use WhatsApp for the conversations where Indian buyers already prefer to reply.

WhatsApp for a B2B SaaS startup in India is the channel for scheduling demos, answering trial questions and keeping onboarding moving with buyers who reply faster there than on email. GullySales sets out how the team uses it for sales and onboarding, with consent and a record in the CRM.

What WhatsApp marketing means

WhatsApp marketing is sending updates, offers and reminders to customers on the app most Indian buyers already check daily. GullySales sets up business WhatsApp, writes the message templates and keeps the list consented and current.

For B2B SaaS startups

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

  • “An owner of a small firm replies on WhatsApp first”

    The founder of a small Indian company reads WhatsApp before email. A demo link sent by message gets opened, and a booking reminder sent there reduces no-shows more than an email that sits in a promotions tab.

  • “Chats stay on one phone”

    When a salesperson keeps the conversation on a personal number, the history leaves with them. A shared business number or a connected tool keeps the thread with the account.

  • “Unwanted messages damage trust and the number”

    Sending product messages to people who did not ask for them annoys the buyer and risks the number being reported. Ask for consent at signup and keep to what the person asked to receive.

  • “Onboarding needs a human voice in the first days”

    A new customer loading data for the first time has small questions that do not justify a support ticket. A named person reachable on WhatsApp makes those questions easy to ask and to answer.

What we do

What we deliver for B2B SaaS startups.

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

  1. WhatsApp Business set-up

    Business profile, catalogue of what you offer, greeting and away message, and a clear owner for the number.

    Result: The number looks like the company and has a named person behind it.

  2. Consent and opt-in wording

    Text for the signup form and demo booking that tells the person what messages they will receive, with a way to stop.

    Result: Every contact on WhatsApp has a recorded opt-in.

  3. Template messages for demos and onboarding

    Short messages for confirming demos, sharing setup steps and checking in after the first login.

    Result: A booked demo has a reminder and an onboarding contact.

  4. Chat-to-CRM logging

    A simple rule or tool connection that puts the key points of each conversation into the account record.

    Result: The next person to pick up an account can read what was said.

  5. Rules for the team

    A one-page guide on tone, who replies, which hours the number is monitored and what to move to email.

    Result: Buyers know what to expect from the number.

How the result is measured

  • Messages delivered
  • Reply rate
  • Enquiries from WhatsApp

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

What to capture or send

WhatsApp suits the conversations where a small-firm owner replies first.

A demo confirmation with the link
Send the time, the meeting link and the person who will attend. Record that it was delivered.
First days of onboarding
A message from a named person offering help with the first step. Record the questions asked.
A quick answer to a pricing question
Reply with the plan and the pricing page link. Record the plan discussed so the next message does not repeat it.
Consent to be messaged
Asked at signup, in writing. It decides who receives product notes and who must not.
Chat summary into the CRM
Logged by whoever held the chat. It keeps the deal record complete when the phone changes hands.

Who it is for

This is written for these B2B SaaS startups.

  • Early-stage SaaS selling to Indian SMEs and mid-market firms
  • Vertical SaaS for one trade, such as clinics, schools, dealers or builders
  • Developer tools and APIs sold to engineering teams
  • HR, payroll and compliance software for growing companies
  • Finance and accounting tools sold through CA firms
  • Indian-built SaaS selling to buyers in the US, UK or Middle East
  • Spin-offs from services firms that turned an internal tool into a product
  • Bootstrapped founders who have not raised and cannot hire a sales team yet

Not for

It is not the right fit if.

  • Your buyers are enterprise teams that expect email and a procurement process, so WhatsApp would sit outside how they decide.
  • The team has no consent wording, so messages would reach people who never agreed.
  • Chats stay on the founder's personal phone and nobody else can read them.

How it works

How the whatsapp marketing work runs

The work itself, in order. How an engagement starts, from your brief to a written scope, is set out on our method page.

  1. 1

    Read the chats you already have

    We read how customers write to you, which questions repeat and where a chat goes quiet. The repeated questions decide what gets automated first.

  2. 2

    Sort the list and the permission

    Contacts who asked to hear from you are separated from numbers that only sit in a phone book. We agree the wording new contacts will see before they say yes.

  3. 3

    Choose the app or the API

    One phone and a small team can stay on the ordinary app. Several people on one number, templates or a CRM link need the API through a provider, which is its own piece of setup work.

  4. 4

    Write the replies and the plan

    The greeting, away message, saved replies and handover rule are written in your words and approved by you. The message plan and its templates follow.

  5. 5

    Connect the record and test

    Each link carries its source line and each chat lands in the CRM. We test on real phones, including a customer who asks for a person.

  6. 6

    Read the unanswered questions

    A question the first reply could not answer becomes a new saved reply or a fixed handover. Stop requests are watched too, with the number's quality rating where the API is used, since both show a message plan that has gone too far.

Where this fits

Three pieces of sales work, in this order.

This work sits inside sales process design, at stage 0, foundation. The audit comes before it, and sales management keeps it running.

  1. Step 1

    Sales audit

    Find where deals are being lost and what to fix first.

    Start here if you cannot say where orders are lost.

  2. Step 2 · you are here

    Sales process design

    One written way to sell, from first enquiry to repeat order.

    Start here if every salesperson sells differently.

  3. Step 3

    Sales management

    A target, a review routine and someone who owns the number.

    Start here if the team has targets and no routine.

FAQ

Questions owners ask before they call.

Not here? More answers, or ask on WhatsApp.

Tell us what you need
Do we need the WhatsApp Business API?
For a small team, the WhatsApp Business app is a start. Once several people share a number or you want automated templates, the API through an approved provider becomes relevant. Check the platform's current rules and costs before choosing.
Can we send product updates to all customers?
Only to those who agreed to receive them, and with relevant content. Sending everything to everyone is how a business number gets blocked. We set a short list of message types and who gets each.
Is WhatsApp suitable for enterprise buyers?
Large companies prefer email and formal channels for contracts and security reviews. WhatsApp suits scheduling and quick answers, with decisions and documents confirmed on email.
Is WhatsApp suitable for enterprise buyers?
For the first contact with a small-firm owner, yes. For an enterprise buyer, email and a meeting link carry the process. Ask the buyer which they prefer and record it, since a message on the wrong channel looks careless. Check the platform's current rules for business messaging.
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.
What do you need from us?
Your brief, and a conversation. After that, access to whatever this work touches, such as your website, your accounts or your enquiry record, and time with the people who handle your enquiries.
What if we are not happy with the work?
Tell us and the plan changes. Everything is reported against the baseline, so a number that is not moving is visible to both sides. The term is in your written scope, and the refund and cancellation policy sets out the rest.
