Should a pilot be paid?

Frequently yes, when the buyer's internal cost is real. Payment is less about revenue than about commitment: an organization that has allocated budget has also allocated attention, and the internal conversation about outcomes proceeds differently. Some vendors credit pilot fees against a first-year contract.

How long should a proof of concept run?

Long enough to answer one technical question and no longer. Feasibility tests that extend for months have usually accumulated additional requirements and become unpaid implementation work, which is a different exercise with a different risk profile.

What is the most common reason a successful evaluation does not convert?

No agreed next step. When success criteria are defined but nothing specifies what happens once they are met, a positive result produces no obligation to act, and the opportunity drifts until priorities shift elsewhere.

Proof of concept vs pilot: why the difference decides who pays

In shortA proof of concept tests whether something can work; a pilot tests whether it should be adopted. They carry different commitment, scope, and success criteria.

A proof of concept tests whether a solution can technically work in a specific environment, while a pilot tests whether it delivers enough value in real conditions to justify wider adoption. The terms are used interchangeably in most enterprise conversations, and the confusion is expensive: the two carry different levels of commitment, involve different people, and are judged against different definitions of success.

Proof of concept vs pilot at a glance

Question answered — PoC: can this work here? Pilot: is this worth adopting?
Environment — PoC: sandbox, test tenant, or isolated instance. Pilot: production or production-adjacent.
Data — PoC: sample, synthetic, or a limited extract. Pilot: real operational data.
Users — PoC: technical evaluators. Pilot: the people who would use the product daily.
Duration — PoC: days to a few weeks. Pilot: weeks to a full quarter or longer.
Commercial status — PoC: commonly unpaid. Pilot: frequently paid, sometimes credited against a first-year contract.
Success criteria — PoC: technical, binary, verifiable. Pilot: outcome-based, requiring judgment.
What follows — PoC: a decision to proceed with evaluation. Pilot: a purchase decision or an expansion decision.
Who signs off — PoC: an architect or technical lead. Pilot: a business owner, usually with budget authority.

What a proof of concept is

A proof of concept is a bounded technical exercise that answers a feasibility question. It typically exists because someone with veto power over the architecture has a doubt that documentation cannot resolve: whether the product integrates with a particular system, whether it handles a specific data format, whether performance holds at the organization's volume, whether it can be deployed inside the required network boundary.

A well-scoped PoC has three properties. The question is written down before work starts. The answer is verifiable rather than interpretive. And the scope is narrow enough that a negative result is cheap.

PoCs go wrong when they expand. A feasibility test that accumulates additional requirements becomes an unpaid implementation project, and the organization running it starts treating the vendor as a supplier of free engineering rather than as a candidate. The tell is that the exit criteria keep moving — each satisfied requirement produces another.

What a pilot is

A pilot is a limited but real deployment. Actual users do actual work in it, with actual data, for a defined period. The question is no longer whether the product functions but whether it produces enough value in the organization's real conditions to justify the cost of adopting it broadly.

That makes a pilot a materially larger commitment on both sides. The buyer has to select participants, run training, adjust process, and accept some disruption. The vendor has to provide onboarding, support, and often configuration work. Because the cost is real, pilots are more often paid than not, and a paid pilot is a meaningfully stronger signal of intent than a free one.

Pilots also expose things a PoC cannot: whether people adopt the product without being pushed, whether it survives contact with edge cases in the buyer's data, and whether the operational burden matches what was described. Those are the findings that determine whether a purchase survives its first renewal.

How they relate

In a full enterprise evaluation the two are sequential — feasibility first, value second. Many evaluations skip one. A product with an obvious technical fit may go straight to a pilot. A deeply technical product may end at a successful PoC and move directly to contracting, with the pilot phase collapsed into onboarding.

Problems arise when the two are conflated. The most common pattern is a PoC scoped like a pilot: real users, real data, production expectations, but no budget, no defined end date, and no agreed decision at the end. That arrangement can run for months and frequently terminates in a no-decision loss, because nothing in its design ever required anyone to decide.

The inverse also happens. A pilot scoped like a PoC — narrow, technical, short — produces a positive technical result that no business owner feels obliged to act on, and the deal stalls waiting for a sponsor who was never involved.

Which to use when

Use a PoC when the open question is technical. A named person doubts a specific capability, and a demonstration resolves it. Keep the question singular and write the pass condition before starting.
Use a pilot when the open question is value or adoption. The technology is not in doubt; whether people will use it, and whether the result justifies the cost, is.
Use neither when the real obstacle is priority or budget. An evaluation cannot manufacture urgency. Running one against an unfunded requirement produces activity without a decision.
Require a written decision at the end of either. Success criteria, an end date, the named person who evaluates the result, and what happens if the criteria are met. Without the last element, a successful test still leads nowhere.
Charge for pilots when the buyer's cost is real. Payment is not primarily about revenue; it is about establishing that the buyer has committed something, which changes how the internal conversation proceeds.
Put both on a mutual action plan. Dates, owners, and the steps that follow a positive result belong in a shared document, because the gap between a successful test and a signed contract is where most of this work is lost.

The distinction is worth enforcing even when the buyer uses the words loosely. Asking which question the exercise is meant to answer, and who will act on the answer, converts a vague trial into a stage with an outcome — and tracking those outcomes separately is what makes win rate legible for evaluation-heavy sales motions.
