About
Affiliate software built by people who've run the payout spreadsheet
Sentalong exists because running an affiliate program on subscription revenue was needlessly painful — and because the incumbents' pricing models punish exactly the growth they promise.
Why we started
Every founder we knew running an affiliate program had the same drawer of horrors: a spreadsheet reconciling commissions against Stripe invoices, a DM folder full of partners asking when they’d get paid, a fraud scheme discovered three months late, and a January spent reconstructing who owes whom which tax form.
The existing tools solved tracking reasonably well but treated everything operational as an add-on — and priced themselves as a percentage of the very commissions you were struggling to pay. The more successful your program became, the more the software cost. That incentive never made sense to us.
So Sentalong is opinionated by design: flat published pricing, billing-native accuracy across Stripe, Paddle, Lemon Squeezy, and Chargebee, and the entire operational layer — fraud queue, clawbacks, tax forms, scheduled payouts — included rather than gated. Free to validate; $49/month when the channel works; $149/month when it’s serious. That’s the whole pricing page.
What we believe
Pricing that doesn't tax success
Percentage-of-commission platforms earn more every time your affiliate costs grow — a misaligned incentive baked into the business model. We charge one flat subscription and publish it on the website. Our revenue grows when the product stays worth paying for, not when your payouts do.
Commissions follow money, not clicks
Browser events lie: ad blockers, cross-device journeys, and failed payments make click-based tracking quietly wrong. Every Sentalong commission traces to an invoice your billing platform actually collected. When refunds happen, reversals are mechanical, not manual.
Operations are the product
Programs fail on operations, not interest. Fraud review before accrual, clawback ledgers, W-9/W-8BEN collection, year-end summaries — unglamorous plumbing that determines whether a program survives its second year. We ship it as defaults, not upsells.
Your affiliates are yours
The portal runs on your domain under your brand. Your partner relationships, content equity, and data accumulate to you — we stay deliberately invisible.
