The problem

Cannabis accounting is a generation behind every other industry.

01

280E Is Unforgiving

IRC Section 280E disallows ordinary business deductions for cannabis companies. Every dollar of COGS allocation matters. Get it wrong and the IRS takes everything.

02

Still on Spreadsheets

Cannabis-specific excise taxes, cultivation taxes, THC taxes. Most firms still track these in Excel because no software handles them natively.

03

Multi-State Chaos

Oregon, California, Colorado, Michigan, Oklahoma. Every state has different rules, different rates, different reporting. One firm can't scale across all of them manually.
