A well-run POC has a defined scope, success criteria signed by the customer, a timeline, and a clear conversion path to a paid contract.
A Proof of Concept (POC) is a time-boxed engagement where an enterprise prospect uses your product against a defined use case to validate it works before committing to a full contract. Done well, POCs close deals that would otherwise die in evaluation. Done poorly, they become extended free trials that consume CS and eng bandwidth while the customer never signs — the sales version of quicksand.
Only after a qualified opportunity — economic buyer identified, budget confirmed, use case scoped, decision timeline agreed. POCs offered to unqualified prospects are lead magnets, not sales motions. If the customer isn't willing to commit to a decision at POC conclusion, don't run the POC.
Every POC needs a written document (email or one-pager) covering: (1) specific use case and success criteria, (2) start and end dates (2-6 weeks typical), (3) resources committed by both sides, (4) decision the customer will make at POC end, (5) paid or free, and (6) what conversion looks like (contract structure, timing). Without this document, POCs drift into indefinite trials.
Paid POCs (typically $5K-$50K, credited toward the contract if they convert) filter for serious buyers and dramatically increase conversion rates — often from 30% (free) to 60-80% (paid). Free POCs make sense for strategic logos or when the product is early and needs learning. Default should be paid; free is the exception.
Bad criteria: 'evaluate the product.' Good criteria: 'successfully migrate 3 workflows and demonstrate 40% faster processing versus current tool, with sign-off from Ops Director.' Criteria should be objective, measurable, and small enough to complete in the POC window. Vague criteria produce vague outcomes and no decision.
Assign a Solutions Engineer or CS resource as POC owner. Weekly check-in with both sides. Written progress update after each session. Halfway through: honest assessment call — is the POC on track or are we drifting? Final call: joint review against success criteria and immediate transition to contract conversation (not 'we'll think about it').
