Business owners with complex structures (LLCs, trusts, flowthrough entities) get blindsided by massive tax bills because there's no ongoing visibility into tax impact of distributions and transactions.
Connects to accounting systems to flag tax-relevant events (excess basis withdrawals, entity distributions) in real time with quarterly estimated liability updates and planning recommendations.
Subscription $100-500/mo per entity group, or sold through advisory firms as a white-label tool
The pain signals are visceral and expensive — $900K surprise extension payments, excess basis withdrawals creating phantom income. This isn't a nice-to-have; it's a problem that costs business owners tens or hundreds of thousands of dollars per incident. CPAs also hate being the bearer of bad news. High emotional and financial pain on both sides.
~5M pass-through entities file in the US annually. Target is owners with complex structures (multiple entities, trusts) — likely 500K-1M entity groups. At $200/mo average, that's $1.2B-$2.4B TAM. Realistically serviceable market is smaller (tech-forward owners and their advisors), but the B2B2C channel through ~90K CPA firms expands reach significantly.
$100-500/mo is trivial compared to the cost of a single surprise tax bill ($50K-$900K per the pain signals). CPAs already charge $5K-$25K+ for annual tax planning engagements — a tool that automates quarterly monitoring is easy to justify. The white-label channel is especially strong: firms mark up the tool cost inside their advisory fees. Tax planning is one of the few areas where ROI is directly quantifiable.
This is hard. You need: (1) accounting system integrations (QuickBooks/Xero APIs are available but messy), (2) a tax calculation engine that handles pass-through entities, basis tracking, K-1 cascading, and multi-state rules — this alone is months of work and requires deep tax domain expertise, (3) real-time event detection logic for flagging excess basis withdrawals, distributions, etc. A solo dev with strong tax knowledge could build a narrow MVP in 8-12 weeks (e.g., just S-corp quarterly estimates from QBO data), but the full vision requires tax expertise that most developers don't have. Regulatory risk is moderate — you're providing estimates, not filing returns.
The gap is remarkably clear: NO existing product combines real-time accounting data integration with deep pass-through entity tax planning and proactive quarterly alerts. Corvee and Bloomberg have tax depth but no live data. Reach has live data but shallow tax logic. Nobody does proactive alerts. Nobody serves business owners directly. This is a genuine whitespace.
Natural subscription model — tax liability changes every quarter, entity structures persist year over year, and the value compounds as the system learns the client's entity structure. Quarterly cadence creates built-in engagement touchpoints. Annual renewals are near-automatic because switching costs are high (entity setup, historical data). White-label channel creates sticky B2B contracts with advisory firms.
- +Genuine market gap — no product combines real-time accounting data with proactive pass-through entity tax planning
- +Extreme pain intensity with directly quantifiable ROI ($100-500/mo tool vs. $50K-900K surprise bills)
- +Dual distribution channels: direct to business owners AND white-label through CPA firms
- +Strong recurring revenue dynamics with natural quarterly engagement cadence
- +Secular tailwinds: CPA shortage, advisory-over-compliance shift, growing pass-through entity complexity
- !Tax calculation engine is technically complex and requires deep domain expertise — wrong estimates erode trust fast
- !Accounting data from QuickBooks/Xero is often messy, miscategorized, or incomplete — garbage-in-garbage-out risk
- !Regulatory/liability exposure: if your estimate is materially wrong and a client underpays, who is liable?
- !CPA firms may resist a tool that disintermediates their highest-margin advisory service
- !Intuit could build this natively into QuickBooks ecosystem and crush you with distribution
- !Long sales cycles in the accounting industry — firms adopt new tools slowly, often at year-end or during busy season gaps

- “owner withdraw in excess of basis one year, unbeknownst to me from a tax standpoint”
- “gave me a $900k extension payment two days before the deadline”
- “Perfect opportunity to talk to them about doing some tax planning to introduce some predictability”
