This is where the rubber hits the road: my proposed integration of the MEDDPICC, Challenger, Sandler, and SPIN sales methdologies with a modern marketing customer lifecycle ideally suited to large enterprise selling. This integration enables Sales and Marketing teams to align to a company's business plan that invariably is based on maximizing acquired customer market share and their share of the sellable solution footprint within each customer.

Each stage carries a defined set of salesperson Actions, Decision Points, and Exit Criteria that is designed to track in a company's CRM system and drive Forecast quality. The diagram below lays out that mapping in full.

Signals

Before a single seller is engaged, demand is sensed.

Product, partner, and market signals: intent data, partner-sourced interest, and customer activity across the portfolio, are collected and resolved into a Marketing Qualified Lead. The exit criterion is simple but disciplined: a qualified MQL is formed, or the signal is set aside.

Awareness

Sales receives the MQL and engages the prospective decision-makers.

The Awareness stage of the AISDALS/L customer lifecycle

The seller reviews the account, delivers a commercial-insight reframe, runs an awareness call, and works to identify pain, an economic buyer, and a champion before proposing an initial discovery call.

The decision gates: Economic Buyer? Champion? Discovery call booked? – force qualification early. The stage exits as Validated Interest or Not Interested. Cleanly disqualifying here is a feature, not a failure.

Interest

The seller and the customer build a shared Mutual Action Plan, run initial discovery, and qualify material pain.

The Interest stage of the AISDALS/L customer lifecycle

Gates test for real pain, customer agreement to the MAP, and a booked discovery workshop. The exit is a Sales Qualified Lead, or Unqualified.

This is the technical and economic evaluation stage the old funnels ignore.

The Search stage of the AISDALS/L customer lifecycle

The team runs a discovery workshop, handles objections, identifies blockers, develops a counter-strategy against competitors, and proposes decision criteria and a buying process.

The decision gates are dense by design: Competitive differentiation? Compelling event identified? Timeline confirmed? Decision criteria and process agreed? Budget source confirmed? The exit is a Qualified Opportunity (or Unqualified, flagged as caution).

Desire

Now the customer genuinely wants the solution, and the work turns to proving and pricing it.

Technical drafts and partner syncs, an economic proposal, a champion-led proposal review, final proposal collaboration, and economic-buyer alignment all converge here.

Gates confirm technical and economic buy-in and budget. This stage produces three pass milestones in sequence: Technical Win, Economic Win, and a Sales Forecasted Opportunity, the point at which the deal earns a place in the committed forecast.

Action

The transaction. MAP sync, key-stakeholder consensus, paperwork and timeline confirmation, a virtual close, and the legal and procurement hand-offs.

The Action stage of the AISDALS/L customer lifecycle.

Gates verify consensus, legal clearance, and order receipt. The exit is Closed-Won. Critically, this is where lifecycle ownership begins shifting from Sales toward Customer Success.

Like

Post-sale, value has to be realized, not just promised.

The Like stage of the AISDALS/L customer lifecycle

The seller stays close through go-live and final project reviews, books champion scale-out planning, and identifies the next solution hypothesis. The exit is a validated Go-Live: the customer is live and seeing value.

Share

Satisfied Innovators and Early Adopters become a channel.

A description of the Share stage as an entry point into the AISDALS/L customer lifecycle model mapped to enterprise SaaS sales processes (MEDDPICC, Challenger, Sandler, SPIN)
The Share stage of the AISDALS/L customer lifecycle

The team runs scale-out planning, identifies new opportunities with the champion, and converts advocacy into pipeline. The "exit" is Start New Sales Process: a fresh Phase II opportunity or a new SQL inside the account that expands into customer whitespace and grows CLTV.

Love

A description of the Love stage as an entry point into the AISDALS/L customer lifecycle model mapped to enterprise SaaS sales processes (MEDDPICC, Challenger, Sandler, SPIN)
The Love stage of the AISDALS/L customer lifecycle

Lifecycle ownership returns fully to Sales for expansion. The account is now a loyalty and CLTV growth anchor, and Sales begins prospecting the next expansion opportunity which loops the whole model back to Signals.

Post FAQ

What are the nine stages of an AISDALS/L enterprise sales lifecycle?

The nine stages of an Enterprise / Public Sector customer lifecycle suitable for selling multiple solutions into a single customer are Signals, Awareness, Interest, Search, Desire, Action, Like, Share, and Love.

Each carries a defined set of salesperson Actions, Decision Points, and Exit Criteria designed to be tracked in a company's CRM system, driving Project Phase and Whitespace expansion within a customer and optimizing forecast quality.

Project Phase and Whitespace expansion occurs at the Like Stage, spawning new MQLs that loop back for a continuous customer expansion flywheel to drive CLTV growth. In a CRM flow, they exit the current Opportunity flow and restart their own flows, but are shown in the Like and Share stages in the context of the customer lifecycle.

What happens in the Signals stage?

Signals is the demand-sensing entry point, before a single seller is engaged. Product, partner, and market signals: intent data, partner-sourced interest, and customer activity across the portfolio are collected and resolved into a Marketing Qualified Lead.

The exit criterion is simple but disciplined: a qualified MQL is formed from early Interest signals, or the signal is set aside,

How does a deal progress through the early stages (Awareness, Interest, Search)?

In Awareness, Sales engages decision-makers, identifies pain, an economic buyer, and a champion, and exits as Validated Interest or Not Interested. Interest builds a Mutual Action Plan and qualifies material pain, exiting as a Sales Qualified Lead.

Search is the technical and economic evaluation stage: discovery workshops, objection handling, competitive counter-strategy, and agreed decision criteria, exiting as a Qualified Opportunity.

What are the exit milestones in the Desire and Action stages?

Desire is where the solution is proven and priced, producing three pass milestones in sequence: Technical Win, Economic Win, and a Sales Forecasted Opportunity...<strong>the point at which the deal earns a place in the committed forecast. </strong>

Action is the transaction itself (virtual close, legal and procurement hand-offs), exiting as Closed-Won, where lifecycle ownership begins shifting from Sales toward Customer Success.

What happens after the sale?

In the Like stage, value creation begins, led by Customer Success and assisted by Marketing:
<ul>
<li>Sales hands off the project to Customer Success, and begins work on qualifying Phase II expansion and/or New Product opportunities in the customer account.</li>
<li>Customer Success stays close to the customer through to Go-Live where the customer is live and generating KPIs against the project success criteria.</li>
<li>Marketing monitors online signals for project risk signals; Customer Success monitors for off-line risk signals.</li>
<li>Early PR is generated by Marketing at Go-Live with initial project success criteria performance KPIs.</li>
</ul>
In Share, satisfied customers become a promoter channel, leveraging customer advocacy for Sales expansion. Marketing continues to monitor on-line project risk signals, and gathers success criteria performance KPIs that have soaked for a reasonable period and can form a part of a case study and support customer testimonials.

In Love, Marketing leverages success criteria KPIs into case studies and testimonials, and the account becomes a loyalty and CLTV growth anchor.
