AppSumo's terms name a support duty but not a revenue split

The workload

Listing a product on AppSumo as a lifetime deal puts two ongoing jobs on the seller, per the marketplace's own seller-facing page. The seller page states a listed product needs a support plan and that the seller must be "ready to engage — you'll respond to reviews, support customers, and treat Sumo-lings like first-class users." Verified: this is AppSumo's own listing requirement, not a summary of typical practice. The page sets no time limit on that commitment, and lifetime-deal buyers keep the license indefinitely, so support runs for as long as any buyer holds it, potentially years past the window that generated the revenue.

What the documents show

Verified: AppSumo's seller page states the marketplace runs "on revenue share, so we only make money when you do," and that rates are "negotiated based on your product category and expected performance." The page publishes no standard percentage, so no single split can be called typical; each seller's cut is negotiated individually. Verified: AppSumo's terms of use state a Lifetime Deal purchase "typically" carries "a 60-day refund period that begins the day you purchase the Product," during which a buyer can get a full refund "for any reason or no reason at all," subject to exceptions listed separately. The same document assigns support duty to the seller directly: "Partners whose Products you purchase are responsible for providing you with customer and product support," with AppSumo offering only discretionary, case-by-case help. Together, the documents show the seller carrying the support obligation and an undisclosed revenue share, while AppSumo controls the refund policy that decides how much of that revenue is final.

The operating cost

Neither document states a dollar figure, and none is invented here. What is documented: for 60 days after each sale, a seller's revenue from it remains reversible in full, at the buyer's discretion, for any reason or none. Estimated: a seller wanting a real read on a campaign's net proceeds would need to wait out that window past the last sale, then price in the ongoing, undated support obligation the terms describe, since that labor is not capped anywhere in the cited documents.

The stop condition

The documents name a stop condition only for the refund window: 60 days after purchase, a sale is no longer reversible under the standard policy. Editorial: the support obligation has no stated end point; a seller who wants one for support labor has to set it themselves, since the terms describe the duty as open-ended.

• What percentage split has AppSumo actually offered for a product like this one, in writing, before listing?
• How many of the last 60 days' sales are still inside the refund window right now?
• Who on the team answers Sumo-ling support requests, and for how long after the promotion ends?

None of this makes a lifetime deal a bad trade; it makes it a trade with two open-ended line items, an undisclosed revenue share and an undated support duty, next to a firm 60-day refund clock. A founder can read the two pages cited here and price the deal accordingly, rather than after the first support ticket arrives.
