Why Till CFO chooses Rillet and how MCP makes AI-native finance real

The Challenge: Scaling Finance Excellence in a Fast-Moving Market

Bo Weathersbee, CEO and Co-founder of Till CFO, knows the exact moment when finance becomes make or break. "There's a clear inflection point between 10-15 million in revenue," he explains. "Finance either becomes a growth accelerant or a significant drag."

Till CFO has evolved beyond the traditional fractional CFO model to provide what Bo calls an "Ironman suit for full-time finance leaders," AI-native financial infrastructure with human-in-the-loop managed services for companies scaling from $10M to $100M revenue.

But to deliver enterprise-level finance operations, Till CFO needed an ERP that could match their vision for speed and automation.

Why Rillet Won Over the Competition

In summer 2024, Bo evaluated multiple ERP solutions for Till CFO's operations, ultimately choosing Rillet.

Bo recalls, "Andreessen Horowitz backing showed institutional validation, and Rillet’s partnership approach felt genuinely collaborative."

At his previous role leading finance for a non-bank lender, he had achieved a T+5 close as a one-person finance shop. When a bank acquisition required T-2 soft close and T+1 final close, he proved that enterprise-level automation was possible with the right infrastructure.

He immediately ruled out NetSuite, the traditional enterprise choice. "12-18 month implementation timelines are incompatible with fast-growing companies," Bo explains. 

It's also how Bo distinguishes Rillet from what he calls "5th bullet point AI companies,"platforms that built their pitch decks before AI existed and simply tacked on a bullet point. 

"Translation: a bolted-on chatbot that doesn't really work, just to signal they're AI-forward," he says. "Rillet is different."

Immediate Results: From Implementation to 2-Hour Close

Till CFO took a dogfooding approach, implementing Rillet internally before rolling it out to clients. The results exceeded expectations.

"We achieved a two-hour first close immediately after onboarding," Bo reports.

This became the foundation for Till CFO's systematic client implementation process. Key platform features driving these results:

• MCP (Model Context Protocol) integration: Rillet's MCP support allows Till CFO to query product documentation using natural language in the context of live client work, and to begin drafting journal entries directly from workpapers.
• Prepaid amortization: Automatic journal entries with full audit history and seamless Ramp integration eliminated manual tracking spreadsheets.
• Revenue recognition (ASC 606): "This is the biggest differentiator versus QuickBooks," Bo emphasizes. "Contract data flows directly to ARR/MRR waterfalls automatically."
• Multi-dimensional P&L and Balance Sheet: Segment financials by department, cost center, product line — delivering dimensional reporting that legacy ERPs don’t always deliver.
• Advanced access controls: Control panel access enabled sophisticated automation features typically reserved for enterprise implementations.

Results That Matter

• Implementation speed: 2-hour month-end close achieved immediately post-implementation
• Systematic scaling: Replicable process allows rapid client onboarding without quality loss
• Future-ready infrastructure: AI-native architecture positions clients for autonomous finance operations
• Competitive advantage: Clients access enterprise-level capabilities typically requiring 12-18 month NetSuite implementations

Looking Forward: The Autonomous Finance Future

Bo sees the current state as just the beginning. "We're capturing decision exhaust and embedding it for system learning," he explains. "The goal is autonomous finance operations that make forward-looking decisions, not just historical reporting."

For growing companies caught between QuickBooks limitations and NetSuite complexity, Till CFO's approach with Rillet offers a compelling third path: enterprise capabilities with startup speed, powered by AI-native infrastructure.
