our call
Start with Firmhouse — highest vibe code, weakest moat.
Chargebee
While building a basic subscription checkout app with Stripe is straightforward, replacing Chargebee's full enterprise scope is practically impossible with simple AI prompts. Chargebee is not a checkout tool; it is a complex revenue ledger handling multi-gateway tokenization, ASC-606 revenue recognition, usage aggregation, and ERP synchronization.
you can rebuild
- Basic subscription lifecycle (create, upgrade, downgrade, cancel)
- Fixed monthly/annual recurring invoicing
- Hosted checkout pages and simple customer portal
- Standard coupon and flat-discount management
- Basic usage event metering and aggregation
what you lose
- Audit-ready ASC-606 and IFRS-15 ratable revenue recognition reporting for GAAP compliance.
- Pre-built bi-directional synchronization with enterprise accounting platforms like NetSuite, Xero, and Salesforce.
- Out-of-the-box support for 35+ payment gateways with automatic gateway failover routing.
- Turnkey global sales tax calculation and multi-region e-invoicing regulatory compliance.
- Machine-learning powered smart payment retries and dunning flows optimized over millions of transactions.
real moats
- Deep API integrations into 35+ global payment gateways and multi-currency payout networks.
- ASC-606 / IFRS-15 compliant, audit-ready automated revenue recognition engines.
- Two decades of edge-case handling around dunning retries, prorations, and complex enterprise contracts.

Firmhouse
While basic recurring checkout can be hacked together with Stripe Billing in a few days, Firmhouse handles complex EU payment methods (iDEAL to SEPA Direct Debit transitions), dunning, product swaps, and rental asset states. Rebuilding the billing cron jobs is easy; handling failed payment retries, mandate regulations, and payment gateway token migrations without churn is hard.
