Does Your POC End, or Does It Just... Continue?

Idea in Brief

The Problem. Most usage-based vendors never sit down and decide what happens on the last day of a proof-of-concept. The order form is silent on it, so the platform decides by default — and that default is rarely the one a RevOps leader would have chosen if anyone had asked.

The Instinct That's Wrong. Teams tend to assume there's an industry-standard answer here — that POCs either quietly end or quietly convert, and whichever one their contracting stack happens to do is fine, because "everyone does it that way."

The Fix. Nobody does it "that way," because there is no one way. Published vendor terms split into two structurally different camps, and the choice between them is a deliberate design decision, not something to leave to whatever the billing system does when a trial clock hits zero.

Two Camps, and Genuinely No Consensus

Pull the actual published terms of a dozen usage-based vendors, and a pattern falls out fast — it's just not the pattern you'd expect. There isn't a dominant default. There are two.

Camp one treats conversion as silent and automatic. Pinecone's Master Subscription Agreement says usage "following the end of any free trial period... will be subject to Fees on the basis of usage," and no purchase action is required to trigger it. Snowflake's Openflow connector terms say it even more plainly: "Billing commences automatically on Day 61. To avoid charges, you must cancel the trial... before Day 60." Databricks converts a trial signup to pay-as-you-go the moment credits run out, no click required. And in C3.ai's actual signed order form with the City of Rosemead, the deployment phase "automatically converts to the Annual Subscription Phase for four (4) years and eight (8) months... unless Customer timely exercises the Opt Out Right" — and once that deadline passes, it becomes "an irrevocable, nonrefundable commitment."

Camp two insists on an affirmative purchase before anything converts. Salesforce's MSA is unambiguous: the trial "WILL BE PERMANENTLY LOST UNLESS CUSTOMER PURCHASES A SUBSCRIPTION." HubSpot's Terms of Service go a step further — the data itself "may be permanently deleted at the end of the trial" if no purchase happens. Google Cloud requires customers to click "Upgrade"; skip that click, and access simply stops.

Two sets of genuinely sophisticated, enterprise-grade vendors, and they've landed in opposite places. Neither camp is "the" industry standard. There isn't one — which is exactly why this deserves a deliberate answer in your own order form, rather than an inherited one.

Worth Watching: The Regulatory Ground Is Shifting Under B2B, Too

This used to be a purely commercial question. It's starting to have a compliance dimension as well. DLA Piper confirms that California's amended Automatic Renewal Law, effective July 1, 2025, now explicitly defines a "free-to-pay conversion" as an automatic-renewal event — though DLA Piper also confirms "the ARL is limited to business-to-consumer sales only," which is the detail most B2B teams actually care about. Latham & Watkins defines the trigger precisely as any provision where "a consumer receives a product or service for free for an initial period and will incur an obligation to pay... if they do not cancel."

There's one exception worth keeping on your radar. Perkins Coie notes the FTC's now-vacated "click-to-cancel" rule explicitly reached B2B free-to-pay trials, and flags that "some state auto-renewal laws seek to regulate not only business-to-consumer transactions but also business-to-business transactions, such as the recently amended Colorado law." And Reed Smith points to the $62 million Noom settlement as a reminder of just how much enforcement appetite exists around silent conversions generally, even in a mostly consumer-focused rulebook. None of this makes B2B auto-conversion clauses risky today. It does mean treating them as permanently regulation-free would be premature.

The Exhibit: Three Clauses You Can Actually Use

These aren't quotes lifted from any single vendor's contract — they're plain-English versions, written so a mid-level deal desk analyst could paste one straight into a real order form for a roughly $100K deal. All three are variants of the same order-form clause — Conversion to Subscription Term — so you can swap the body text for a different tier without rewriting anything else in your template.

Preferred: Automatic Conversion, With a Real Opt-Out

Unless Customer notifies Vendor in writing before the end of the Evaluation Period that it will not continue, the Evaluation Period will automatically convert into a paid Subscription Term on the pricing and terms set out in this Order Form. At any time before the end of the Evaluation Period, Customer may decline to continue for any reason, without penalty or further obligation, by providing written notice to Vendor.

Use this when: you want the deal to keep moving without a second purchase motion, but you also want a genuine, no-questions-asked exit ramp for a customer who never intended to commit. This mirrors the structure in Common Paper's published Cloud Service Agreement template — it solves camp one's biggest failure mode (billing someone who didn't mean to convert) without reintroducing camp two's friction (forcing a ready buyer back through procurement).

Fallback: No Conversion Without a New Order Form

The Evaluation Period will end on the Evaluation End Date, and Vendor will not charge Customer any Fees during the Evaluation Period. Customer's access to the Services will end automatically on the Evaluation End Date unless the parties execute a separate Order Form for a paid Subscription Term before that date.

Use this when: your buyer's legal or procurement team specifically objects to any automatic billing trigger and insists on an affirmative purchase step. This is the same shape Salesforce and HubSpot both use in their published terms — you'll accept a little pipeline friction in exchange for zero ambiguity about consent to pay.

Approval-Required: Automatic Conversion Into a Minimum Term

Unless Customer notifies Vendor in writing at least [__] days before the end of the Evaluation Period that it elects not to continue, the Evaluation Period will automatically convert into a Subscription Term of not less than [__] months (the "Minimum Term") at the Fees set out in this Order Form. Once that notice period has passed, Customer's commitment to the Minimum Term is non-cancelable, and if this Agreement is terminated during the Minimum Term for any reason other than Vendor's uncured material breach, all remaining Fees for the Minimum Term become immediately due and payable.

Use this when: you have real leverage and a long-term commitment is worth pursuing. This is the structure behind C3.ai's actual signed government order forms, pairing automatic conversion with a locked multi-year term and full acceleration on early termination — aggressive enough that it should get a look from legal or a deal-desk lead before a seller puts it in front of a customer, not after.

The Vantage Point

Revolear sets up dozens of new order forms every quarter for usage-based businesses, and we spend a lot of that time helping our customers' sellers work through exactly this kind of clause. The pattern above — two incompatible camps, a regulatory backdrop that's tightening faster than most commercial teams have noticed, and no real drafting consensus in between — is what we see across nearly every deal desk we work with.

The Takeaway

An auto-conversion clause isn't a technical default your billing platform happened to pick. It's a real commercial decision with downside on both sides: bill someone who never meant to convert, and you've created a support headache and a reputational one. Require a fresh purchase motion from someone who's already decided to buy, and you've added friction to your own pipeline for no reason. Decide on purpose, before the trial clock starts, and write the clause accordingly.
