Key takeaways
- A sales POC tests one or two critical requirements, not the whole product.
- Success criteria are written down and agreed before any work starts.
- A free trial is self-led and open-ended; a pilot is a small live rollout.
- In sales, POC can also mean point of contact, so spell it out the first time.
How a sales proof of concept works
A sales proof of concept works as a small project with a fixed question: can this product do this job, here, for these people? It is usually proposed after a demo, when the buyer likes what they saw but has one doubt that only a test with their own data or systems can settle.
The seller and the buyer write a short plan together. When the end date arrives, both sides compare the result with the criteria and the buyer decides whether to move to a proposal.
- Name the requirement being tested and why it matters to the decision.
- Agree measurable success criteria and who judges them.
- Fix the scope, the data used, the people involved and the end date.
- Hold a short check-in partway through to catch blockers early.
- Review the result against the criteria and agree the next step.
Proof of concept, proof of value, pilot or free trial
A proof of concept asks whether the product can do the job, a proof of value asks whether doing it is worth the money, and a pilot asks whether it works for real users at a small scale. The three often blur, so name which one you are running and what question it answers.
A free trial is different again. The buyer explores the product on their own, with no agreed criteria and often no seller involved. Trials suit simple products bought by individuals; a POC suits a complex purchase where a buying committee needs evidence before it signs.
When a POC is worth running
A POC is worth running when a single, specific doubt stands between the buyer and a decision, and a test can settle it. Technical fit with an existing system, performance on the buyer's own data and a new team's ability to use the product are typical reasons.
It is not worth running when the buyer has no budget, no decision date or no clear question. In that case the POC becomes free consulting and delays the deal. Asking 'if this succeeds, what happens next?' before agreeing to one tells you which situation you are in.
How to keep a proof of concept from stalling
A proof of concept stays on track when it has an owner on each side, an end date and criteria nobody can reinterpret later. Most stalled POCs fail on one of those three.
- Write the success criteria in the buyer's words and get them confirmed by email.
- Keep the scope narrow; add requirements only by agreement and with a new date.
- Name the buyer's owner and make sure they have time set aside for it.
- Agree before starting what a successful result leads to, such as a proposal.
Why POC can also mean point of contact
POC also stands for point of contact, the person you deal with at an account, which is why 'POC' in a CRM note or an email can be ambiguous. When both meanings could apply, write 'proof of concept' in full the first time, and keep the abbreviation for later in the same document.
Where Pebbles Ai fits
- CapabilityProspecting & customer recordsTrack the POC as a deal in the CRM, which is in Beta: a deal holds a stage, amount, close date and probability, and tasks and notes can carry the agreed criteria and dates.
- CapabilityAI workspaceA project keeps the chats about one evaluation together, from drafting the success criteria to the summary you send the buyer at the end.
Common questions
How long should a proof of concept last?
Long enough to test the agreed criteria and no longer. An end date set at the start stops it drifting into an unpaid trial.
Should a proof of concept be paid?
It depends on the effort involved. Short, light tests are often free, while those that need significant set-up or services are commonly charged, sometimes with the fee credited against the contract.
Who should own a POC on the seller's side?
Usually the account executive owns the deal and the timeline, with a sales engineer or solutions specialist owning the technical work. The buyer should name an owner too.
What is the difference between a POC and a pilot?
A POC tests whether the product can do a job, usually in a controlled set-up. A pilot runs it with real users on real work at a small scale, often after the purchase decision is close.
