Many marketplaces and platforms charge their sellers, hosts, vendors or professionals a subscription: a monthly plan to list products, a pro tier with better placement, a software fee for booking or shop tools. These customers are businesses, often small ones, and their decision to stay depends on one thing above all: whether the platform brings them enough revenue to justify the fee. NoChurn works on that seller subscription, not on the payments between buyers and sellers.
What NoChurn covers on a platform
- Covered: the subscription your sellers pay you. Plan payments, failed charges, cancellations, offers, win-back and the seller’s churn score.
- Not covered: buyer orders, payouts to sellers, and disputes between buyers and sellers. Those stay in your marketplace payment setup.
On Stripe, platforms often run seller subscriptions with Stripe Billing next to Stripe Connect, charging connected accounts as customers (Stripe, accessed November 2026). NoChurn connects to the platform’s own Stripe account where those subscriptions are billed. If your seller fees are deducted from payouts or billed by your own system, send subscriptions, payments and cancellations through the REST API.
How sellers pay
- A card on file, often the owner’s personal or business card.
- Deducted from the seller’s balance or payout, when the platform also handles their sales. Then a “failed payment” usually means the seller had no sales that month.
- Direct debit for some European platforms, through GoCardless or Mollie.
- Monthly tiers with an annual option for established sellers.
Why sellers churn
Involuntary churn
- Business cards that expire or get cancelled when a small business changes banks. See expiring cards.
- Empty balances. When fees come from payouts, a slow month means nothing to deduct.
- Failed direct debits after a seller changes bank accounts. See GoCardless failed payments.
Voluntary churn
- Not enough sales. The fee feels like a tax on a channel that is not working.
- Seasonality. Holiday rentals, wedding vendors, tax preparers, garden services: many sellers have an off-season.
- The seller closes or pauses their business. Not a reason you can argue with.
- Moving to another channel, or selling directly.
- Paying for a tier they do not use. Pro features bought at launch, never used since.
How NoChurn handles it
Failed payments
On Stripe, NoChurn retries failed payments at times based on the decline reason and likely paydays, or you can keep Stripe Smart Retries. On other billing tools, the provider’s dunning stays and NoChurn adds AI-written emails and a card update link next to it. Emails can be reviewed before they go out. For sellers, it helps to speak business language: “your shop will be hidden on the 15th if the plan is not paid” is clearer than a generic billing notice. The hosted card update page keeps card data with your payment provider. See failed payments.
Cancel flow that follows the seller’s business
| Reason | Offer that fits |
|---|---|
| Not enough sales | Plan change to a lower tier, keeping listings live |
| Off-season | Pause until the season starts |
| Closing or pausing the business | Pause, or let them go with their data kept |
| Too expensive | Discount for a few months |
| Moving to another channel | Ask what is missing, then let them go |
A one-click “cancel now” button is visible on every step, and a cancel that is asked for is carried out. Sellers talk to each other, and a platform that is hard to leave gets a reputation quickly. Use the hosted modal in your seller dashboard, or build the screens with the headless API. See cancel flows and pause vs discount.
Churn score with seller signals
Each seller gets a score from 0 to 100 at signup and on every change, from payment method, signup source and the custom data you send. Seller data is the strongest signal you have: a seller whose orders drop for two months is far more likely to cancel than one whose orders are growing. When a seller removes their card before a renewal, the score goes up. See churn score.
Win-back
Sellers who cancel get win-back emails at 30, 60 and 90 days, written from their cancel reason. A seasonal seller can be invited back before their season; one who left over sales can hear about what changed on the platform. See win-back.
Chargebacks on seller fees
Sellers sometimes dispute your subscription fee with their bank, often after a disagreement about the platform. On Stripe and Braintree, NoChurn gathers evidence (cancel flow answers, emails sent, usage, support conversations) and drafts a reply with AI, sent only after a person reviews it. Disputes on other providers are shown read only. This covers your fee only, not disputes on buyer orders. See chargebacks.
Custom data worth sending
listings_activeorders_last_30_daysandorders_trend: up, flat or down, computed by you.seller_revenue_band: a band you choose, rather than exact amounts.last_login_at: last visit to the seller dashboard.reviews_countorratingcategoryandcountryplan,billing_intervalandsignup_source
NoChurn shows which attributes go with churn, with sample sizes. Correlation, not causation: sellers with few listings may churn more because they were never serious, not because the listing limit pushed them out. See custom data.
Integrations that fit
- Stripe, in one click, for seller subscriptions on Stripe Billing.
- Chargebee or Recurly if your seller plans run on a billing platform.
- Any billing by API when fees come from payouts.
- Zendesk, HubSpot or Intercom for seller support, read only.
What to watch out for
- Separate seller churn from buyer churn. NoChurn works on the seller subscription. Buyer retention is a different problem.
- Fees from payouts. If you deduct fees from earnings, a failed charge is a sales problem, not a card problem. Write the emails accordingly.
- Large sellers. Your biggest sellers probably have an account manager. Use NoChurn’s score to tell that person early, not to replace them.
- When NoChurn is not the right tool. If your platform earns only a commission on each sale with no seller subscription, there is no recurring charge for NoChurn to work on.
Pricing
Every feature is on every plan, and the price depends only on your MRR from seller subscriptions: free up to $300, then from $9 a month in small steps up to $399 at $500k, custom above. NoChurn never takes a share of recovered revenue. See pricing, or the pages for B2B SaaS and product-led SaaS.
