As a founder or CFO at a growing company, you’re juggling competing priorities. But when you’re scaling fast, it’s easy to make financial missteps that can stall your growth or cost you significantly in the long run.
Here are five common financial mistakes growing companies make, along with practical fixes to keep your business profitable and stress-free.
1. Weak Financial Controls
Without clear approval workflows and separation of duties, spending drifts. Department heads sign up for tools, vendors get paid without proper review, and by tax season or audit time, the books are a tangle that’s expensive to unwind.
Fix It:
- Put a simple approval matrix in place: who can approve what, up to which amount.
- Keep operating, payroll, and tax funds in separate accounts for clarity.
- Have finance review a monthly spending summary with department leads, so nothing surprises you.
2. Leaving Tax Savings on the Table
Overlooking R&D tax credits, state incentives, proper entity structure, and timing of deductions can cost growing companies tens of thousands each year. Many founders don’t realize what’s available until a CPA points it out, often after the window has closed.
Fix It:
- Work with a CPA who understands growth-stage companies to review your tax position annually.
- Track qualifying R&D activities throughout the year, not just at tax time.
- Use your accounting software to tag potentially deductible expenses as they happen, so nothing gets missed.
3. Wasting Time on Manual Bookkeeping
If your team is still using spreadsheets or entering transactions by hand, you’re burning hours that should go toward analysis and growth. Manual processes also introduce errors that compound over time and surface at the worst moments, like during an audit or fundraise.
Fix It:
- Set up bank feeds to auto-import transactions daily into your accounting system.
- Automate AP/AR workflows with tools like Bill.com or Ramp instead of manual approvals over email.
- Block time weekly for finance to review the books and run key financial reports, so issues surface early.
4. Ignoring Cash Flow Planning
Many growing companies focus on revenue but overlook cash flow. Even if you’re profitable on paper, poor cash flow management can leave you unable to make payroll or invest at the right moment.
Fix It:
- Maintain a 13-week rolling cash flow forecast to anticipate shortages before they hit.
- Set up automatic alerts for low balances and large upcoming outflows.
- Review the forecast weekly with leadership, so cash decisions stay proactive instead of reactive.
5. Not Getting Help Soon Enough
Trying to run finance with a bookkeeper when the business needs a controller is one of the most expensive mistakes a growing company can make. Founders often wait too long to bring in senior finance help. The result? Missed opportunities, costly errors, and major cleanup projects that could have been avoided.
Fix It:
- Consider a fractional controller or outsourced controllership engagement to get senior-level oversight without the full-time hire.
- Start with a systems and books assessment to find the gaps before they become crises.
- Outsource routine work like reconciliations and payroll so your team can focus on growth.
Take Control of Your Financial Future
