Stop Running Your Business from Your Bank Balance

About Francesca & Thornley and Knight

‍

Francesca Thornley is the founder of Thornley & Knight, a bookkeeping firm she's grown over 11 years to a team of nearly nine. The company name traces back to her great-great-grandfather's Victorian-era paint company in England — one that supplied paint for the royal family's carriages and was known for inclusive hiring practices well ahead of its time. Francesca built the firm around a flexible, lifestyle-first model: roughly half her staff are homeschooling moms, and the business is designed around the idea that performance matters more than where or when you work.

The Profit First System

‍

Francesca is a proponent of the Profit First method — a framework built on one core idea: pay yourself first, then build your business obligations around what's left. In practice, this means setting up separate bank accounts for distinct money purposes: owner's compensation, taxes, profit, and operating expenses. Every dollar that comes in gets distributed across those accounts on a regular schedule (weekly or twice weekly) based on predetermined percentages.

The result? You can open your banking app and know at a glance whether payroll will clear, whether your tax bill is covered, and how much is actually available to spend on something like marketing. No guesswork, no stress, no running your business off a single account balance that hides what's already spoken for.

The Biggest Money Mistakes Small Business Owners Make

‍

Francesca sees the same patterns repeatedly in businesses that are struggling:

• Mixing personal and business finances. If you're running a corporation and treating your business account like a personal piggy bank, you're "piercing the corporate veil" — effectively removing your own liability protection if you're ever sued.
• Bank balance accounting. Logging in, seeing money, and spending it — without accounting for taxes owed, payroll coming up, or obligations already committed. This is how business owners end up with a giant IRS bill and no money to pay it.
• Not paying themselves. Too many owners 5 or 10 years in still don't take a regular paycheck. Francesca's advice: start somewhere, even if it's $100 a week, and build from there.
• Waiting too long to invest in marketing. Once revenue slows, it's too late to start. The marketing flywheel takes time to spin up — you need to be allocating a percentage from the beginning, even if you're not spending it yet.

On Marketing Budgets

‍

The conversation gets into the real relationship between money management and marketing spend. The framework:

• Allocate a consistent percentage of revenue to marketing — typically somewhere between 2–20% depending on your industry, goals, and whether you're B2B or B2C.
• Understand your customer acquisition cost vs. your lifetime customer value. A bookkeeper signing a $60K/year client can justify spending $5K to acquire them. A candle shop selling $50 products cannot.
• Don't blow the whole budget at once out of enthusiasm. Think drip system, not firehose. Spend what you can sustain, build traction, reinvest.
• If you don't know your numbers, you can't have a meaningful conversation with a marketing agency. The budget conversation requires knowing your margins first.

Practical Takeaways

‍

• Set up separate bank accounts for taxes, payroll, profit, and operating expenses
• Put yourself on a regular paycheck — even a small one — from day one
• Require autopay from recurring service clients; it's worth months of follow-up to get them there
• Learn what a P&L and balance sheet are (ask ChatGPT for a fifth-grade explanation if needed)
• Hire a bookkeeper before tax season, not during it
• Review your margins — you may be selling products or services at a loss without realizing it

The Bottom Line

‍

Accounting isn't rocket science, and no professional should make you feel like it is. The goal is understanding how money flows through your business well enough to make confident decisions — about hiring, marketing, growth, and everything else. When the financial system is in place, the rest gets a lot easier.
