Lead qualification is the process of deciding whether a lead is worth a salesperson's time, by asking a fixed set of questions about budget, authority, need, timing and, in the newer frameworks, pain, process and champion. BANT is the oldest and shortest, MEDDIC the most thorough, CHAMP and GPCTBA/C&I the buyer-centred revisions. None of them asks whether the lead can be reached, and in the BounceZero corpus, April to October 2026, 14.5% of business lead addresses were invalid and 27% unconfirmed. This guide compares the frameworks, scores them for deal size, and adds reachability as the first gate.
Each framework is a list of questions. The table shows what each asks, how long it takes to run, and the deal size it fits. Reply-rate style numbers do not apply here; the comparison is structural.
| Framework | Questions | Call time | Fits | Weakness |
|---|---|---|---|---|
| BANT | Budget, Authority, Need, Timing | 10 to 15 min | Transactional and mid-market, under $25k ACV | Seller-centred; budget first scares early buyers |
| MEDDIC | Metrics, Economic buyer, Decision criteria, Decision process, Identify pain, Champion | 2 to 4 calls | Enterprise, multi-stakeholder, over $50k ACV | Heavy for small deals; needs a champion to exist |
| CHAMP | Challenges, Authority, Money, Prioritisation | 15 to 20 min | Mid-market, consultative | Same four facts as BANT reordered; less adopted |
| GPCTBA/C&I | Goals, Plans, Challenges, Timeline, Budget, Authority, Consequences, Implications | 20 to 30 min | Inbound-heavy teams, SaaS | Long; reps shorten it in practice |
| SPIN | Situation, Problem, Implication, Need-payoff | 20 to 40 min | Complex consultative sales | A questioning method more than a qualification gate |
Call time is the typical span to collect all answers, not a single call length. MEDDIC answers accumulate across the sales cycle.
The acronyms hide different purposes. Picking by purpose avoids running an enterprise framework on a $3,000 deal.
Four yes-or-no facts. If budget does not exist, authority is three levels away, need is vague and timing is "next year", the lead goes back to nurture in fifteen minutes. Best used as a gate before a demo, not as the whole discovery. Ask need and timing first; budget last.
Built for deals with a buying committee. Metrics gives the business case, the economic buyer is the signature, decision criteria and process map the path, pain is the reason, champion is the person inside who sells for you. Not a call script; a checklist the opportunity must satisfy before forecast.
BANT reordered so the challenge comes first and money last. Useful for consultative sales where asking about budget in minute two kills rapport. Same information, different order.
Designed for inbound leads who already know the product. Goals and plans establish context, consequences and implications make the cost of inaction explicit. Long enough that most teams run a trimmed version.
Every framework assumes the conversation is happening. Qualification starts after contact. But most leads never get to a call, and a share of them never could, because the contact data was wrong. A lead with a dead email address, a wrong phone number and a LinkedIn profile at a previous employer fails every framework by default, after consuming the research time to fill in the first two letters of the acronym.
The corpus puts a number on it. Of 6.5 million non-freemail (business and ISP) addresses on lead lists verified between April and October 2026, 14.5% were invalid, 2.3% were on catch-all domains and 27% could not be confirmed. Only 32.6% were positively deliverable. Freemail addresses on the same lists were 17.6% invalid. By country, Australian business lists ran 36.5% invalid. The full cut by provider and country is on the benchmarks page.
Reachability is therefore the zeroth question. It costs one verifier call at the moment the lead is created, and it is the only qualification question that can be answered by a machine before anyone picks up a phone.
A scorecard turns a framework into a number that routes the lead. This one uses BANT questions plus reachability, scored out of 100, for a mid-market SaaS. Swap the questions for MEDDIC above $50k ACV.
| Question | Strong answer | Points | Weak answer | Points |
|---|---|---|---|---|
| Reachability | Email verified valid, phone confirmed | Gate open | Email invalid or role | Score 0, back to data |
| Reachability | Email catch-all or unknown | Cap at 60 | ||
| Need | Named problem with a cost | 30 | General interest | 10 |
| Timing | Decision inside 90 days | 25 | No date | 5 |
| Authority | Speaking to the buyer or a champion | 25 | Researcher with no path up | 8 |
| Budget | Line item exists or can be created | 20 | No budget, no owner | 5 |
Thresholds: 70 and above is sales-qualified; 40 to 69 goes to a nurture sequence with a re-qualify task in 30 days; below 40 returns to marketing. A capped lead cannot pass 60 until a reply or a call confirms the contact.
A sequence for a lead that arrived through a form, a database export or a trigger event.
Email through the verifier at creation, phone through a connect attempt or a carrier lookup. Invalid email and no phone: the lead goes to a data-fix queue, not to a rep.
Headcount, industry, geography, stack. If the company is outside the profile, qualification stops here regardless of the person's enthusiasm.
Under $25k: BANT or CHAMP in one call. Over $50k: MEDDIC across the cycle. Inbound: a trimmed GPCTBA/C&I.
The order matters more than the acronym. A buyer who has explained the problem and the deadline will discuss money. One asked about money first often will not.
Fill the scorecard, apply the thresholds, create the opportunity or the nurture task, and record which answers were confirmed versus inferred.
A job change, a funding round or a reply to a nurture email re-opens the scorecard. So does a failed re-verification: if the address dies, the lead drops back to the data queue.
Qualifying from the database field instead of the conversation. "Budget: yes" because the company has 500 employees is a guess. Record inferred answers separately from confirmed ones and weight them at half.
Running MEDDIC on every lead. The enterprise framework takes several calls to complete, and a $5,000 deal does not survive that cycle. Match the framework to the deal.
Treating a bounced email as a qualification result. It is a data result. The lead may be perfect; the address is wrong. Route to the data queue, find the current address, and re-enter the process.
Never re-qualifying. Answers age. Budget cycles end, champions leave, and the address that was valid in January is among the four in five that the BounceZero decay study found no longer valid after 90 days. A ninety-day re-check on open leads, including a re-verification of the contact data, keeps the pipeline honest.
Order of questions for any framework: can we reach them, do they fit, do they have the problem, when will they decide, who signs, is there money. Reachability costs nothing to ask and removes one lead in seven before a rep spends a minute.

Budget, Authority, Need and Timing. A lead is BANT-qualified when there is money for the purchase, the contact can approve it or reach the person who can, a real problem exists, and a decision is expected within a defined window. It dates from IBM's sales training and remains the fastest framework to run, which is why it is still used as a pre-demo gate.
As a disqualification gate, yes. As a discovery method, it is usually replaced or reordered, because asking about budget first suits the seller rather than the buyer. CHAMP reorders the same four facts to lead with the challenge; MEDDIC expands them for enterprise deals. Most teams run BANT questions in a different order rather than abandoning them.
BANT is four facts collected in one call and used to decide whether a demo is worth running. MEDDIC is six elements collected across the sales cycle and used to decide whether an opportunity belongs in the forecast. BANT fits deals under about $25k with one decision maker; MEDDIC fits deals over about $50k with a buying committee and a champion.
Yes, as the first step rather than part of the framework. A lead whose email is invalid cannot be qualified by any method because the conversation never starts. Verifying at lead creation costs one API call and, on corpus data, removes about one lead in seven before it reaches a rep. Catch-all and unknown results should cap the score until a reply confirms the contact.
Four to six. Need and timing first, then authority, then budget, with reachability already answered by the verifier before the call. More than six on a first call turns discovery into an interrogation. MEDDIC answers accumulate across several calls rather than being asked in one.
