The best POC pricing is the one that validates value fast without devaluing your product. At Referly, now Sonik, we tested every POC and pricing strategy we could think of: free tests, free trials, discounted POCs, fixed-price POCs. The one we kept is a paid POC at full price with an exit clause. Here is what each one taught us, the hard way.

Why POC pricing is a sales problem, not a pricing problem

Founders tend to treat the proof of concept as a pricing question: how much do we charge for the first 30 or 60 days. It is really a qualification question. The way you structure the POC decides who commits, how seriously they test, and whether there is a second negotiation at the end.

In B2B SaaS with a real onboarding and a complex pain, the POC is the sale. If the structure is wrong, you win the POC and lose the deal three months later.

I sold cloud projects at Google Cloud for five years before building Referly, so I had seen the enterprise version of this. What I had not seen was how differently it plays out for a startup where every deal in flight is a runway question.

The 5 POC pricing strategies we tested

1. The free test: the rookie mistake

Zero commitment produces zero qualification. People barely test, barely engage, barely care. You spend your onboarding hours on a prospect who had no reason to show up to the second call, and the "results" of the test say nothing because nobody used the product.

In our experience, a free test also tells the buyer what you think your product is worth. They remember.

2. The free trial: the product guy mistake

On paper, a product that sells itself is tempting. And it works for products targeting SMBs with a price below $200 a month, where the user can see the value alone in an afternoon.

The moment your product solves a complex pain or needs onboarding, forget it. Users never see the real value alone. And unless you have a flood of inbound leads, every non-conversion is a cost: support time, infrastructure, and the opportunity to have sold properly.

3. The discount during the POC

Starting a relationship on a lie. You anchor low, you devalue the product, and the customer will try to keep the discount forever. The renewal conversation becomes a fight about getting back to list price, which is a conversation you can only lose.

4. The fixed-price POC

Perfect for large enterprises. At Google Cloud we used fixed-price cloud migration audits to secure a first commitment before a much larger migration project. The audit had its own scope, price and deliverable, and it de-risked the big decision for the customer.

For a startup? Long cycles plus a second negotiation at the end equals dangerous burn. You close the POC, deliver, and then start the real sales cycle from scratch, with a procurement team that now knows exactly how much they can push.

5. The exit clause: the one we kept

The prospect signs the real contract at the real price, with a clause that lets them exit after a defined period if agreed success criteria are not met. You protect your price. You give flexibility. And the next steps are already pre-negotiated, because there are none: if the POC works, the contract simply continues.

One pricing anchor. One legal process. One clear path to rollout. The prospect commits, tests seriously, and moves forward faster.

How to structure an exit-clause POC

1. Price at list. Annual or monthly, the same price the customer will pay in year two. No POC discount.
2. Define success criteria with the champion before signing. Two or three numbers, measurable in the product. For a dialer, conversations per rep per day and meetings booked are the obvious ones.
3. Set the window. Long enough to see the numbers, short enough to keep urgency. In our experience, 4 to 8 weeks for a sales tool.
4. Write the exit clause plainly. If the criteria are not met by date X, the customer can terminate with Y days notice and owes nothing beyond the period used.
5. Run onboarding as if it is already a customer. Because it is. The exit clause is the safety net, not the plan.
6. Review the criteria at the midpoint. If the numbers are off, fix usage before the exit date, not after.

Common mistakes with SaaS POCs

• Letting the prospect define success after the fact. Without criteria agreed up front, every POC ends with "we need more time".
• Running POCs with no champion. If nobody internally owns the outcome, the exit clause gets used regardless of the results.
• Combining strategies. A discounted fixed-price POC with a free month is three mistakes at once.
• Copying enterprise playbooks. What worked for a cloud migration audit at Google does not work for a 15-person startup with 4 deals in flight.
• Measuring the POC on usage instead of outcomes. Logins are not value. Meetings are.

How Sonik approaches POCs

We still sell the way the fifth strategy describes: a real contract at list price, with an exit clause tied to criteria we agree on with the sales leader before the kick-off. For a parallel dialer, those criteria are the ones we publish in our benchmark: conversations per rep per day (our north-star is 20) and meetings booked.

It keeps the sales cycle to one negotiation, and it means our onboarding team treats every POC as a customer from day one, because contractually that is what they are. Pricing is on the Sonik pricing page.

Conclusion

A POC should prove value fast without teaching the customer that your product is cheap. Free tests do not qualify, free trials do not onboard, discounts anchor low and fixed-price POCs create a second negotiation. The exit clause does none of that. This week, look at your open POCs and write down the success criteria for each one. If you cannot, the POC is a free test with extra paperwork.
