About the company
Helios sells industrial automation SaaS to factory operators across Japan, Germany, and Mexico. Their customers are technically sophisticated and already comfortable with self-custody — but that didn't translate to reliable monthly renewals.
The challenge
- Invoice-and-pay model was losing 8% of renewals a month to customer inattention, not payment intent.
- Support team spent 14 hours/week chasing renewals by email and Slack.
- Churn was elevated not because customers wanted to leave but because they forgot to pay.
The solution
- Introduced ERC-20 allowance subscription as the recommended autopay mode.
- Built a migration flow to ask existing customers to upgrade from invoice to allowance — 84% did within two months.
- Used OpenSettle's dunning to detect allowance exhaustion and prompt top-up automatically.
The results
- Monthly churn dropped from 3.4% to 1.1%.
- Support tickets on billing fell 62%.
- $2.1M of ARR previously at risk was locked in on autopay.
