3 Mistakes Cannabis Startups Make with Cash Flow—and How to Fix Them

Title: 3 Mistakes Cannabis Startups Make with Cash Flow – And How to Fix Them

‍‍By a CPA Who’s Seen It All in Cannabis Finance

In the cannabis industry, where federal illegality creates barriers to banking, taxes hit harder than most entrepreneurs expect, and compliance is king, cash is everything. And yet—too many cannabis startups treat cash flow like an afterthought.

Here are the top three cash flow mistakes I see cannabis companies make (even the ones with good products and traction), and how to correct them before it’s too late.

Mistake #1: Underestimating the Impact of 280E

The Problem:
Many cannabis founders assume they’ll be taxed like any other small business. They don’t realize Internal Revenue Code §280E disallows deductions for most ordinary business expenses if you're trafficking a Schedule I substance—which cannabis still is at the federal level. That means your gross profit—not your net income—is taxed.

The Consequences:
You might be profitable on paper but still owe more in taxes than you can afford in cash. I've seen startups burn through cash reserves or go into debt just to cover their tax bills.

The Fix:
Start tax planning on Day One. Work with a cannabis-specific accountant to:

• Segment your financials (e.g., cost of goods sold vs. non-deductible SG&A expenses)
• Evaluate legal entity structures (like separating your operations and real estate to isolate 280E exposure)
• Model quarterly cash needs based on realistic tax obligations.

Mistake #2: Not Separating Personal & Business Funds

The Problem:
Founders often inject personal funds into the business or use the company account to pay personal bills. Without proper documentation and clear entity boundaries, this creates a compliance nightmare and obscures true cash flow.

The Consequences:

• You can’t track actual cash burn or runway.
• You risk piercing the corporate veil.
• IRS or state audits may disallow key deductions or reclassify transactions.

The Fix:

• Open and maintain dedicated business bank accounts—even if you're operating mostly in cash.
• Log personal contributions as loans or capital infusions, not revenue.
• Use accounting software to track all inflows/outflows by category and class.
• Set up a basic chart of accounts that aligns with cannabis-specific reporting needs.

Mistake #3: Ignoring Cash Flow Forecasting

The Problem:
Because startup founders are busy chasing licenses, hiring, and building brand awareness, forecasting often takes a back seat. But without a rolling 13-week cash forecast, you’re flying blind.

The Consequences:

• You don’t know when you’re going to run out of money.
• You miss opportunities to renegotiate payment terms, delay expenses, or raise funds proactively.
• You can’t spot seasonality or cyclical dips in revenue until it’s too late.

The Fix:
Build a 13-week rolling cash forecast and update it weekly. This tool helps you:

• Identify timing gaps between cash inflows (sales) and outflows (payroll, taxes, inventory purchases).
• Make data-driven decisions about hiring, expansion, or inventory purchases.
• Build credibility with investors, lenders, and strategic partners.

Even better—integrate this forecasting into your monthly financial review. You'll spot issues early and move with confidence.
