Sales Demo · PoC
Sales Demo / Proof of Concept
What is a sales demo?
- Demo = showing the value
- PoC = validating results in the real environment
- Agree on success criteria up front
What demos and PoCs really change is the basis of the conversation. Until then, everything we say is a claim that things will improve, and the customer has to translate it into their own company’s situation as they listen. The moment the customer’s own forms and supplier names appear on screen, the debate shifts from “will it work?” to “who starts using it, and when?” This is the point where the review shifts from a feature comparison chart to real work. We are effectively writing the line our contact will take to their boss, and in meetings we are not part of, that line makes the case for us.
A demo and a PoC are different things. A demo runs 30 to 60 minutes in our environment with data we prepared, so the risk of failure is low, but it can’t overcome the objection “that’s just a well-made sample.” A PoC usually runs 2 to 6 weeks on the customer’s account, data, and network, and requires a security review and IT team cooperation. It is the stage where we pay with our own time and people to erase the objection. It differs from a pilot, where a few teams adopt the product after contract signing, in that the purpose is validation, not expansion.
More than half of a PoC is the agreement you sign before it starts. Write numbers, time frame, and people together, such as '30% shorter processing time, error rate under 1%, 6 business users working with it for 4 weeks,' and put in the same document when, by whom, and to which committee the result goes once the criteria are met. Success criteria and the next approval date belong on one page, so that validation leads to a contract. A PoC without that sentence is free usage, not validation, and even when it goes well it ends with 'we liked it.'
The most common failure in the field is showing off features. Walk through thirty menus in 45 minutes and the customer is left with one impression, “complicated,” while the month-end close they were worried about never gets touched. Overusing PoCs costs just as much. Put two engineers on four weeks at a company with no confirmed budget or approval chain, and it often ends up as leverage to push a competitor’s price down. It is better to set an internal rule: no PoC until budget, timing, and approver are confirmed.

Consider a hypothetical case. We were pitching a logistics management solution to Company A, a food distributor with KRW 120 billion (≈ US$89,780,000) in annual revenue and 380 employees. Company A handled orders by Excel and phone, so month-end close took five days, and its inventory error rate had climbed to 2.4%. Two competitors had already submitted proposals.
- In the first meeting, when Park, head of the logistics team, said, 'The features look similar across all three vendors,' the sales rep set aside the standard demo and first asked for two weeks of Company A's March purchase orders and a sample of its supplier codes.
- On demo day, when Company A's form layout and real supplier names appeared on screen, Park said, 'This is our warehouse screen.' On the spot, Park asked the finance director to join and they booked a 40-minute second demo.
- The PoC was designed for four weeks, 2 centers in the Seoul metropolitan area, and 6 field staff. Success criteria were narrowed to two, order processing from 12 to 7 minutes per order and an error rate below 1%, and written into the agreement.
- In the same agreement, they wrote 'if the criteria are met, submit to the investment review in the second week of November,' and agreed that we would draft the review materials and submit them under Park's name.
- In week 2, the error rate stalled at 1.8% because of a barcode scanner integration error. A 30-minute weekly check-in with Kim from IT led to a settings change, and everything was back to normal in week 3.
- After four weeks, processing time dropped to 6.4 minutes per order (47% faster) and the error rate fell to 0.8%. The project passed investment review in one round, and we signed a company-wide rollout contract for all 3 centers just three and a half months after first contact.
