Why Cash Stability Matters

One of the most common post-sale questions is:
“How much cash should I keep after a windfall?”
Founders often assume the answer is small — but early obligations (estimated taxes, lifestyle changes, new expenses) require flexibility.

Understanding Your Immediate Obligations

Common founder concerns include:

  • Estimated tax payments after a liquidity event
  • Upcoming charitable commitments
  • Deferred comp or earn-out timing
  • Real estate plans
  • Early-stage family expenses

A clear list helps define how much liquidity is required.

Bank Structure and Protection Basics

Many sellers also ask:

  • “Which banks can safely hold large balances?”
  • “How do FDIC and SIPC limits work for a $10M or $20M balance?”

While bank protection rules are defined by regulation, knowing how accounts are titled is part of safe operational structure.

Short-Term Parking Options

Founders sometimes explore:

  • T-bills
  • Treasury-only money markets
  • High-quality cash vehicles

These can offer stability while long-term planning is underway. Suitability varies by individual needs.

When to Evolve Beyond Cash

Cash prevents mistakes early on, but eventually founders ask, “How should I invest after selling my business?”
That answer depends on a broader plan, not the urgency of the moment.

Founder Questions to Revisit Quarterly

  • Am I overexposed to single institutions?
  • Have obligations changed?
  • Does the cash structure still reflect my needs?
