Lead qualification frameworks: BANT, GPCT and MEDDIC in a WhatsApp conversation

Qualifying a lead means deciding, with evidence, whether it deserves a seller’s time now, later or never. The best-known lead qualification framework is BANT, a public model that checks budget, authority, need and timeline, but it is not the only one: GPCT, MEDDIC and CHAMP change the order and depth of the questions. In practice, in a WhatsApp conversation, five to seven well-written questions do most of the work, as long as they lead to a clear rule for handing the lead to a seller.

What does it actually mean to qualify a lead?

Not every inbound contact is an opportunity. Some have the problem and the urgency. Some are researching for six months from now. Some are outside your profile and will never buy. Qualifying means sorting these groups before spending a meeting on each one.

Good qualification answers three questions, in this order:

1. Is there a problem we solve? Without pain there is no sale, just a chat.
2. Is there capacity to buy? Budget, decision power, timing.
3. What is the right next step? A meeting with a seller, content to let it mature, or an honest “this isn’t for you.”

The most common mistake is treating qualification as a form to fill in. It is a diagnosis. What matters is not having every field complete, but knowing enough to decide the next step.

BANT vs GPCT vs MEDDIC vs CHAMP: what is the difference?

All four are public frameworks, created and popularized by the sales profession over decades. None is best in absolute terms. Each fits a type of sale.

Framework	What it checks	Where it works best	Weak spot
BANT	Budget, Authority, Need, Timeline	Short sales, mid-size deals, an easy-to-find decision-maker	Opens with money; can disqualify buyers who haven’t yet recognized the pain
GPCT	Goals, Plans, Challenges, Timeline	Consultative and inbound sales, when the buyer is still framing the problem	Longer; needs a seller who can run discovery
MEDDIC	Metrics, Economic buyer, Decision criteria, Decision process, Identify pain, Champion	Complex sales, long cycles, buying committees	Too heavy for a first conversation or a fast sale
CHAMP	Challenges, Authority, Money, Prioritization	B2B sales where pain should come before budget	Less structure for mapping the buying process

Which framework fits your sale?

• Short cycle, one decision-maker, mid-size deal: BANT, with need asked before budget.
• Consultative sale, leads from content or referrals: GPCT or CHAMP. Start with the goal and the challenge.
• Large contracts, buying committee, months-long cycle: MEDDIC, but applied across the deal, not in the first conversation.

Most B2B companies selling over WhatsApp, which is how a large share of business is done in Brazil and many other markets, sit in the middle: consultative sale, cycle of weeks, one or two decision-makers (often the owner or a partner). For them, a blend works best: the pain and goal from GPCT or CHAMP, with the authority and timeline from BANT. Budget comes at the end, not the start.

The questions that actually qualify a lead on WhatsApp

On WhatsApp the conversation is short, asynchronous and informal. A twelve-question form kills it by question four. What works is a small set, each question with a clear purpose.

1. Trigger: “What made you look into this now?” Reveals the pain and, as a bonus, the urgency. The most valuable question on the list.
2. Current state: “How are you handling this today?” Shows the size of the problem and what you would replace (a spreadsheet, another supplier, nothing).
3. Goal: “If this works, what changes for you three months from now?” The “G” in GPCT. Gives the seller the success criterion for the meeting.
4. Fit: “How many people on the team would be involved?” Confirms the company fits your profile without asking for revenue up front.
5. Decision: “Besides you, who else is part of this decision?” The “A” in BANT, asked without awkwardness. Tells you whether the partner needs to be in the meeting.
6. Timeline: “Do you have a date in mind to get started?” Separates who is buying this month from who is researching for next half.
7. Investment (optional, when it fits): “Is there already a budget set aside for this, or is it still being defined?” Open-ended, no number, and only after the pain has surfaced.

You don’t need all of them. If the buyer said in their first message that they own the company and want to start next week, skip five and six.

How to write the questions so an AI SDR can ask them naturally

More and more, the first WhatsApp conversation is handled by an AI SDR. The same questions work, but how you write them changes. A few rules that apply to people and agents alike:

One question per message. Two questions together get one answer, usually to the easier one.

Acknowledge the last answer before the next question. “Got it, so today it all lives in a spreadsheet. How many people on the team work with it?” reads like a conversation. Questions with no bridge read like a form.

Write the objective, not just the wording. Instead of handing the agent an exact sentence, tell it what to find out and why: “find out who else takes part in the decision, so we know whether the partner should join the meeting.” That lets it adapt to what the buyer has already said.

Define what happens when the buyer goes off-script. If they ask for the price in their second message, the answer should come from the company’s knowledge base, and qualification resumes afterwards, without pretending the question wasn’t asked.

Let questions be skipped. A question the buyer ignored should not come back three times. Record it as “not provided” and move on.

Save every answer to a field. A question that doesn’t become data in the CRM is lost. Each question above should map to a field on the contact, so the seller can read it in ten seconds.

When should a lead be handed to a seller?

The handoff is where qualification proves itself. Without a written rule, the SDR (human or AI) passes everything along, and sellers stop trusting the queue. A simple rule that fits on one line of your process:

Hand off to the seller when:

• there is a pain the company solves, in the buyer’s own words;
• the buyer fits the profile (size, segment, use case);
• you know who decides, and they will be in the meeting or have been mapped;
• the timeline fits the company’s window (for example, starting this quarter);
• the buyer has accepted a meeting with a date and time.

Don’t hand off, but keep nurturing, when the pain is real and the timeline is far away. That lead gets content and a follow-up scheduled for the right moment.

Remove from the funnel when the buyer is outside the profile. Saying so clearly and politely is a good outcome too.

What travels with the handoff

The seller should never repeat questions the buyer already answered. The handoff needs to carry: a summary of the pain, the goal, who decides, the timeline, what the buyer has already asked, and the full conversation. If the seller opens the meeting with “so, tell me a bit about yourselves,” the qualification was wasted.
