Inversion Selling - MATH Qualification

MATH Qualification:
The Framework That
Actually Predicts Closes.

BANT was built in the 1960s for IBM. MEDDIC was built in the 1990s for PTC. Both assume sellers control information. MATH was built for a world where buyers know as much as sellers - and qualify themselves.

Why Existing Frameworks Fail

BANT and MEDDIC Were Built for a Different Buyer

BANT - Budget, Authority, Need, Timeline - asks sellers to extract information from buyers to qualify deals. MEDDIC adds structure but maintains the same assumption: the seller is the more informed party who must uncover what the buyer needs to know. That assumption broke when buyers gained information parity. Running a BANT or MEDDIC qualification on a buyer who has already researched your competitors, read your case studies, and benchmarked your pricing feels like an interrogation, not a conversation.

BANT - Budget

Seller asks: Do you have budget?

MATH - Misery: Buyer states their own Cost of Inaction. When the buyer quantifies what inaction costs them, budget discussions become irrelevant - they find the budget.

BANT - Authority

Seller asks: Are you the decision maker?

MATH - Access: Buyer confirms who decides and agrees to engage them. Assumed authority is not authority. Confirmed access changes the deal.

BANT - Need

Seller identifies the need

MATH - Harm: Buyer verifies the specific consequence of not solving the problem. Seller-identified needs create objections. Buyer-acknowledged harm creates urgency.

BANT - Timeline

Seller asks: When do you want to buy?

MATH - Timing: Buyer owns a real external deadline with real consequences. If the timeline exists because the seller created urgency, it is not a real timeline.

The MATH Framework

Four Elements That Must Be Buyer-Acknowledged

M

Misery - The Cost of Inaction

The specific financial, operational, or strategic cost of doing nothing. Must be calculated by the buyer, stated by the buyer, owned by the buyer. No misery number, no deal. This is the foundation of every Inversion Selling engagement.

A

Access - Confirmed, Not Assumed

Confirmed access to the economic buyer, technical buyer, and any veto holders. The buyer must acknowledge who decides and agree to engage them. Assumed access is the most common reason deals stall at late stages.

T

Timing - External Urgency Only

A real deadline with real consequences that exists independent of seller-manufactured urgency. Board dates, regulatory deadlines, competitive triggers. If the urgency disappears when you stop pushing, it was never real.

H

Harm - Buyer-Verified Consequence

What specifically happens to the buyer - personally and organizationally - if they do nothing. Harm makes the Cost of Inaction tangible. It is the difference between a problem the buyer acknowledges and one they are compelled to solve.
