You need server-side purchase verification, entitlement management, token security, paywall configuration, and subscription lifecycle sync. You can build it in-house — or buy Tierux and have your AI agent set it up in minutes.
| Factor | Tierux (buy) | In-house build |
|---|---|---|
| Time to launch | Minutes via AI agent over MCP | 4–8 weeks per platform |
| Setup cost | Free to start, then $39/mo flat | $20k–$60k+ in engineering time per platform |
| Token security | Encrypted vault — tokens never stored raw | Build and audit your own token handling |
| Server-side verification | Store-verified on our servers, zero-trust client | Build, maintain, and audit your own |
| Cross-platform support | Android + iOS unified entitlement model | Separate implementations per platform |
| Ongoing maintenance | Zero — managed platform | Ongoing — store API changes, security patches |
| Paywall configuration | Remote config — change without app release | Hardcoded — requires app release to change |
| Subscription lifecycle sync | Play RTDN fully handled; App Store notifications wired, hardening in progress | Build your own webhook handlers |
| Win-back / cancellation offers | Built-in for Google Play; App Store — not yet | Requires custom implementation |
| Risk of missing edge cases | Handled by platform | Your team owns all edge cases |
Building in-house gives you full control and zero external dependencies beyond the stores. The trade-off is engineering time, ongoing maintenance, and the risk of missing edge cases that a managed platform has already solved.
Tierux is pre-launch — we're honest about our stage. But the infrastructure we provide (server-side verification, encrypted token vault, entitlement management) replaces what would otherwise take weeks to build yourself.
You want to ship fast — your AI agent sets up billing in minutes. You need cross-platform support — Google Play today, App Store in progress. You value predictable flat pricing and don't want to maintain billing infrastructure. Your team should focus on your product, not purchase verification code.
You have dedicated engineering capacity for billing infrastructure, your app is single-platform, you have specific security or compliance requirements that require full control, and you're willing to absorb the ongoing maintenance burden as store APIs evolve.
4–8 weeks per platform × senior engineer = $20,000–$60,000+ upfront, plus ongoing maintenance for store API changes, token security patches, and subscription lifecycle updates. Cross-platform doubles this.
Free to start. $39/mo Pro for up to 1,000 subscribers. At 10,000 subscribers: $309/mo — $3,708/year. Even at larger scale, a fraction of one engineer's time. And your agent sets it up in minutes.
