Stop discovering tax strategies too late.
Real-time tax intelligence. Surface opportunities earlier, grow advisory revenue, stay proactive year-round.
01 · Event detection
Catch the trigger when it hits the GL.
bunnyOS reads your clients' books through the year, not at extension. When a 179 window opens or an S-corp threshold crosses, the alert lands with the strategy attached.
02 · Contextual reasoning
April reads the whole client, not one signal at a time.
April connects GL activity, tax profile, prior returns, and entity structure. A single signal is often noise. The same signal alongside three others is usually a strategy.
03 · Firm intelligence
Turn insights into advisory revenue.
Verified vs. potential savings across your roster. Top firm-wide strategies. Savings multiplier on every dollar of fees. The advisory ROI you've never been able to quantify.
CPA firms charge clients $200 to $500 per month for proactive tax advisory.
bunnyOS is the system that makes it deliverable for your firm.
