| BANT | Budget, Authority, Need, Timeline | IBM, usually dated to the 1950s or 1960s | Fast first-pass qualification of inbound leads and simple sales | SDR or inside sales | First call | Asks for budget before value is shown; misses buying groups |

| SPIN Selling | Situation, Problem, Implication, Need-payoff | Neil Rackham and Huthwaite, book published 1988 | Discovery in larger sales where the buyer must build their own case | Account executive; SDRs use the problem and implication questions | Discovery | A questioning method, not a checklist; says little about sign-off |
|---|
| CHAMP | Challenges, Authority, Money, Prioritisation | A later rework of BANT; attribution varies | Outbound first calls where budget is not set yet | SDR | First call | Light on the decision process and competition |
|---|
| GPCTBA/C&I | Goals, Plans, Challenges, Timeline, Budget, Authority, Negative consequences, Positive implications | Developed by HubSpot for its own sales team | Consultative mid-market sales led by the buyer's goals | Account executive or senior SDR | Discovery | Eight elements is a lot for one call; easy to run as a script |

| Sandler Selling System | Bonding and rapport, Up-front contract, Pain, Budget, Decision, Fulfilment, Post-sell | David Sandler, founded Sandler in 1967 | Teams losing deals to stalls, free consulting and think-it-overs | Whole team; SDRs use the up-front contract and pain funnel | Every call | Needs training and practice; can feel blunt if done badly |
|---|
| The Challenger Sale | Teach, Tailor, Take control | Matthew Dixon and Brent Adamson, CEB, book published 2011 | Buyers who are happy with the status quo and complex sales | Account executive, with insight-led openers for SDRs | Opener to close | Needs a real insight; without one it reads as arrogance |
