Verticals
Built for the platforms that serve Main Street.
Embedded treasury isn't a generic feature. The payment flows for a gym management platform — instructor ACH payouts, membership billing cycles — are structurally different from those of a field services SaaS routing job completion payments to dozens of independent contractors. We built the KYB logic, virtual account structure, and rail defaults for each vertical specifically.

Explore Field Services →Why Now
Treasury is the highest-margin feature a vertical SaaS can add.
A vertical SaaS platform charging $99/month for software may charge $299/month once it holds the business's bank account, runs ACH payroll, and issues instant contractor payouts. The economics are well-documented across the BaaS category. The infrastructure barrier — FBO account negotiations, KYB program design, sub-ledger architecture, NACHA originator compliance — has historically been the obstacle. That's the problem Mainstreetspine solves.
- Revenue per platform increases with payment volume, not seat count
- SMBs consolidate banking into their management software when given the option
- Churn drops significantly when a platform holds the business's bank account
- Real-time payment data creates new cross-sell opportunities
