Profitability
Find the margin leaks, pricing gaps, and avoidable costs that keep a busy business from becoming a healthy one.
Las Vegas business consultant
I help owner-run businesses make more money, waste less money, and build systems that hold up when the pressure is on.

The point of the work
A business can look busy and still be quietly losing money. I focus on the decisions that change that.
My work sits where strategy meets the day-to-day: payment costs, pricing, sales, customer experience, marketing, and the operating habits that turn revenue into durable profit.

David Sapper is the founder of BlueFinch Advisors in Las Vegas. Much of our work starts face to face: we visit businesses, meet the people running them, and discuss how customers buy, how payments work, and where the owner sees pressure. An on-site conversation adds context that a statement or spreadsheet cannot show.
A restaurant, retail shop, or service business may have similar expenses but very different operating needs. A busy checkout, a delayed estimate, or a payment system that creates extra steps can affect both the customer experience and the time available for productive work. The useful question is where a practical change would make the greatest difference.
What a business review coversYou do not need a complete plan before reaching out. A concrete concern gives the conversation a useful starting point: processing costs that are hard to explain, prices that no longer cover the work, or a team spending too much time handling exceptions.

Payment processing, explained
What looks like one expense on a bank statement can involve several decisions: how customers pay, what each transaction costs, when the money arrives, and how much work the team does to keep records straight. A useful review connects all four.
Start with the real cost of credit card processing. Use complete statements to calculate the effective rate, then account for equipment and software billed separately. If you are evaluating an offer, compare proposals using the same sales and transaction counts. A lower percentage can still produce a higher bill.
When the question is cash flow, follow the transaction through to the bank. The deposit reconciliation guide explains how to distinguish timing differences from unexplained adjustments, with a worked example and a short exception checklist.
If a change is warranted, use the processor-switching checklist to review contracts, equipment, staff training, and reporting before moving. The goal is an understandable arrangement that works for the people running the business.
Calculate your effective processing rate with a private, on-page tool. No statement upload is needed.
