Profit Theory is not a lender. Providers make all funding decisions; approval is never guaranteed.

Operating cash flow vs. profit

Profit on your P&L isn't the same as cash. Loan principal, owner draws, inventory and slow receivables all use cash without showing as expenses. Lenders care about cash available to repay debt.

Common questions

What's net cash flow?

Total cash received minus total cash paid out in a period.

How is this used by lenders?

They compare cash available for debt service with loan payments (DSCR).

How much cushion should I keep?

Many owners aim for several months of fixed costs; it depends on how predictable revenue is.
