The Nine Stages of the AISDALS/L Enterprise Sales Lifecycle

This is where the rubber hits the road: my integration of the MEDDPICC, Challenger, Sandler, and SPIN sales methodologies with a modern marketing customer lifecycle ideally suited to large enterprise selling. This process design enables Sales and Marketing teams to align to a company's business plan that invariably is based on maximizing acquired 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, built to live in the CRM rather than in a spreadsheet. The Sales, Partner and Professional Services lanes are modelled as process steps on the Lead and the Opportunity; the Marketing lane runs as triggered flows and activities against the same records, and Customer Success runs its own process from Like onward.

Critically, steps do not tick themselves because a rep says so: each one completes only when a real, properly linked CRM activity completes. The process bar is a progress ledger for forecasting and management, not a task list; reps work from their activity queue in a dashboard. That is the difference between a process that reports reality and one that reports optimism. The stage cards below lay out that mapping in full.

Stage 1: Signals

Before a single seller is engaged, demand is sensed. This is Marketing's stage to own, before a Lead arrives in Sales.

Product, partner, and market signals: intent data, partner-sourced interest, and customer activity across the portfolio are collected and scored. Signals is deliberately not a process stage with salesperson actions; it is a scoring subsystem sitting upstream of the seller. Scores accrue per product against a per-product threshold, so a single account can carry several product-level leads at once, each with its own visibility.

The exit criterion is simple but disciplined: the threshold is crossed and a Marketing Qualified Lead is formed, or it is not. There is no rejection list and no "not ready" recycle: a below-threshold contact simply sits in the liminal space between Marketing and Sales until it converts. Nothing is thrown away, and nothing is counted early.

Two entry points, one process

Not every deal starts at the same point. Existing vs New Customer is the entry-point gate, and it is judged at the account level. A genuinely new logo enters at Awareness, and so does a Whitespace Expansion Lead, because the fit of a different solution is unproven and the Champion and Economic Buyer may be different for larger organizations. A Project Expansion Lead, for a phase the original proposal left unscoped, keeps the account review and the partner check, skips the rest of the Awareness outreach and goes straight to proposing the discovery call.

The reason is that "awareness" means awareness of the company, not just the solution. With an existing account you have already proven the firm, cleared procurement and legal, established value, and banked an internal reference from a prior champion. That is the substance of the Awareness outreach, already earned for a further phase of the same project. An unknown vendor faces brutal friction where a known one faces nominal friction, and the process should not pretend otherwise.

Stage 2: Awareness

Sales receives an MQL, or creates the Lead themselves, and engages a prospective champion / decision-maker.

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.

Economic Buyer? appears here as a soft check, and that is deliberate. Qualification is progressive: the economic buyer question is asked early, carries forward unanswered, and hardens later in Desire, where a final "no" closes the deal as lost. Asking early builds the habit; enforcing early just teaches reps to guess. Champion? is asked here too, and must be answered before the Lead converts: a "no" returns the Lead to Account Review to find one. The stage exits as Validated Interest or Not Interested, and cleanly disqualifying here is a feature, not a failure.

Stage 3: Interest

The seller runs initial discovery, qualifies material pain, sends the Executive Point-of-View after the first discovery call, together with the first version of a Mutual Action Plan (MAP) that asserts mutually-agreed-on control over next steps, and proposes a deeper-dive discovery workshop.

Qualify Material Pain is the hard gate here: the pain has to be stated in the customer's own terms, across situation, problem, implication and need-payoff, and a "no" ends the Lead. Confirming what the problem costs, and the materiality threshold that would justify a budget, comes later, in Search.

The exit is a Sales Qualified Lead, and it has a precise definition: booking a discovery workshop triggers the conversion to SQL, and the Lead later converts to an Opportunity once its qualifying steps are complete, with the Champion confirmed and material pain qualified. Sales-qualified is an evidence-based event in the system, not a subjective opinion.

Stage 4: Search

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

The team runs a discovery workshop, confirms material pain against the materiality threshold, agrees the MAP, and agrees decision criteria and a buying process.

Material Pain? is the hard gate here: the customer confirms both what the problem costs and the materiality threshold that would justify a budget, and a final "no" closes the deal as lost.

MAP Agreement? works differently: a "no" means you rework the plan and re-present it, and only a final "no" is a loss.

Objections are handled the same way wherever they surface: in or after the workshop, and after each later review meeting through to the economic buyer, the team identifies blockers and develops a counter-strategy. That captured content becomes high-value win/loss analysis data later.

The decision gates are dense by design, but they do different jobs.

• Competitive differentiation? is not a qualifier and does not recycle anything; it is a readiness milestone confirming the team can actually articulate why you win.
• Compelling event identified? captures both the driver and its date.
• Timeline confirmed? has to be articulated by the customer, and it is measured against the champion's own estimate of how long their process takes: when the process runs longer than the runway to the compelling event, you can see the trouble from here.

Timeline confirmed, criteria agreed, process agreed and budget source identified are each answered from the discovery workshop, as separate steps, because each captures different data. MEDDPICC qualifiers themselves live on the Opportunity record, not in the process bar: a step earns its place only if it is an action or a decision. Accumulated data is stored on the Opportunity form that is leveraged in downstream steps.

The exit is a Qualified Opportunity, or a deal closed as Lost.

Stage 5: Desire

Now the customer genuinely wants the solution, and the work turns to proving and pricing it. Competitive risk may still remain through to the proposal acceptance, but it is narrowed and the competitive threats are understood well enough to mitigate.

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

The centre of gravity is the Key Stakeholder Alignment meeting. After the champion has approved the draft proposal, it tests that proposal with all the stakeholders at once rather than taking the champion's word for it. Champions close to a rep give optimistic answers; converged confirmation exposes that, and once everyone has publicly committed, backsliding is socially expensive. Where the economic buyer is in that room, the same meeting settles economic buy-in and puts the deal in the forecast.

These gates separate two things that are routinely confused.

• Economic buy-in means the economic buyer wants it.
• Budget confirmed means the money exists and has been released.

Both are required, and the economic buyer question that was optional back in Awareness now hardens: a "no" sends the proposal back for more work, and only a final "no" closes the deal as lost. The champion, required since the Lead converted, must now approve the proposal on the same terms.

The economic proposal is where the value arc closes its first loop: price is reconciled against the pain cost and materiality threshold captured in Search, and turned into agreed, measurable success criteria.

This stage produces three go/no-go milestones in sequence: Technical Win, Economic Win, and a Sales Forecasted Opportunity.

Note what this forecast is: it is the Sales team forecast, not the Company's dependable commit. The Company's dependable commit is earned at the next Stage when the Close Map has consensus from the buyer's Key Stakeholders.

Stage 6: Action

The transaction: the Close Map, legal pre-clearance, a virtual close, then the signable package, and the procurement hand-off.

Legal runs in parallel, not in series: EULAs and draft templates go out early for pre-clearance, and the redlines that come back feed the final signable package.

Gates verify legal clearance and order receipt, including the partner's order where a partner is involved. Before the signable package goes out, though, is the Virtual Close: a dry run of the entire closing sequence, designed to surface the hidden obstacle before it costs you the quarter. Clearing hidden obstacles is what promotes the deal from sales-forecasted to company-forecasted commit that senior management can depend on.

The exit is Closed-Won, which is the trigger for the handover to Customer Success, though the handover itself is executed in Like, where success objectives transfer clearly, not just the contract.

Stage 7: Like

Post-sale, value has to be realized, not just promised. Customer Success and the success metrics have to deliver on the promise.

The Like stage is long by design, and the process has to know the difference between a stage that is soaking and a deal that is stalling.

Two reviews do two different jobs:

• The Go-Live Review proves operational success: the solution is live, working, and actually adopted. It is not a value measurement.
• The Final Review, scheduled 60 days after go-live is approved, is the value measurement: achieved value and actual pain reduction, measured against the exact success criteria agreed back in Desire.

Customer-measurable KPIs simply do not exist before the solution has been operationalized and has had time to soak. This is where the value arc closes: pain is qualified at Interest, materiality quantified at Search, priced and agreed at Desire, and proven at Like, and it is what makes the expansion conversation possible. If the solution fails to deliver on its success criteria, expansion fails.

Like is where the handoff to Customer Success happens, and transfers the promises: the pain addressed; the success criteria measured; the complete stakeholder map; not just a signed contract. That handoff is a common point at which customer expectations and objectives disconnect from the outcomes, and is where 56% of organizations that experience high regret over their largest technology purchase in the past two years (Gartner 2022), and the renewal and satisfaction measures point the same way.

Like is also where Sales' expansion efforts begin. With a delivered success and a champion who will talk to their peers, Customer Success books the scale-out meeting with Sales and the champion, where the customer decides whether to proceed and names the next champion, and the seller identifies the next solution hypothesis: the inside track that reveals other business units and problems no competitor can see.

Both expansion motions spawn their new Lead here, at project completion, once the Final Review is accepted and the customer confirms at the scale-out meeting that it wants to expand. A phase that was scoped but sits behind a go/no-go gate requiring the customer's approval enters as a later-stage Opportunity instead.

Stage 8: Share

Satisfied customers become a new marketing channel by sharing their experiences with peers. Customer Success-sourced opportunities have the highest win rate of any source (ICONIQ 2026), and 48% - 63% of new ARR comes from expansion as companies scale (KeyBanc and Sapphire Ventures 2024).

Sales responsibility handed over at the close in the Action stage, and Customer Success runs Like, Share, and Love with support from Marketing. Marketing asks the customer for written permission to name them, Marketing turns the proven numbers into a champion testimonial and a case study, and the customer is asked for references and referrals. A referral enters as a new Lead at Awareness.

The expansion Leads spawned at project completion are qualified or disqualified in their own Lead process. There are two distinct motions, and conflating them is a mistake: Whitespace Expansion cross-sells a different solution to a delivered customer, so fit is unproven and it must genuinely re-qualify. Project Expansion grows the same solution into the phases the original proposal left unscoped.

Both follow the same rule, and it is the most important rule in the model: an Opportunity is never spawned automatically. Automation may create an MQL: the unqualified foundational state, because generating one early costs nothing. Promotion to Sales Qualified stays a Sales judgement call. Automation that manufactures qualified pipeline manufactures unearned forecast, distorting the pipeline.

So the "exit" is Start New Sales Process. A Project Expansion Lead skips the Awareness outreach and goes straight to proposing the discovery call, because the company is already known; a Whitespace Expansion Lead begins in Awareness, because its Champion and Economic Buyer may be different. Those records run their own lifecycle; they are shown here only in the context of the customer lifecycle. That is what expands into customer whitespace and grows CLTV.

Stage 9: Love

Love collects the longer success criteria soak, still owned by Customer Success and supported by Marketing. When the early success criteria measured at the Share stage are proven as sustainable, the customer sees the seller as more than transactional - they see the seller as committed to their success, and the risk of churn or competitive defection is low.

When this process is followed consistently, sellers create fans that are highly resistant to customer churn, and who become a reliable marketing channel and source of CLTV growth.

The account is now a loyalty and CLTV growth anchor. Sales has no remaining actions here: Sales handed over at the close, and the expansion Leads already left at project completion to run their own cycles.

What continues is retention: Customer Success holds two value check-ins and reads the risk, Marketing monitors online risk signals, and the renewal flow consumes both. The lifecycle then returns to Sales, to nurture the champion and economic buyer or to rest dormant. This is what makes the sales process a flywheel rather than a funnel: the loop does not restart with a stranger, but inside an account that has already paid you, already proven the value, and already told you where the next problem lives.
