Where each shekel of revenue goes, and which link breaks first

Revenue

Gross profit

⁦₪60,000⁩⁦60%⁩

  • Operating expenses⁦-₪35,000⁩⁦35%⁩
  • Marketing⁦-₪10,000⁩⁦10%⁩⁦₪500⁩ per new customer

Net profit

⁦₪15,000⁩⁦15%⁩

Each bar is a share of revenue. The two marks on a bar are its red and green thresholds for a service business.

Every link holds in the green, by the service business thresholds.

How we calculated it

Gross margin is 60%: revenue minus direct delivery costs, divided by revenue. Net profit is ₪15,000: revenue minus direct costs, operating expenses and marketing spend, before tax. That is a net margin of 15%.

CAC is ₪500, marketing spend divided by new customers. Growth against the same month last year is 25%.

The colors assume a service business: gross margin is green from 40% and red under 20%, net margin is green from 15% and red under 5%, growth is green from 10% and red below zero. A trading or retail business runs on lower gross margins, so compare it with its own sector.

This is a simplified, illustrative tool meant to give you a quick feel for the numbers. It is not professional advice. Real business decisions depend on many factors it does not account for, and all results are estimates only. Mobius Business Solutions accepts no responsibility for decisions or actions taken based on this tool.

Most small business owners do not need a big financial system on day one. They need five numbers they can understand, check and use.

The point is not to become an accountant. The point is to stop making decisions from the bank balance alone.

1. Operating cash

Operating cash is the money the business can actually use after setting aside VAT, tax reserves, payroll and other payments already committed. It is not the balance you see in the bank.

If the account shows NIS 50,000 but NIS 18,000 of it belongs to VAT, taxes, salaries or suppliers due soon, the business does not have NIS 50,000 to spend.

2. Cash collected

Revenue invoiced is not the same as cash collected. A business can issue invoices, record revenue and still wait weeks or months for payment. This is where cash flow (money moving in and out) usually breaks.

This number tells you whether customers are funding the business or you are financing your customers. If collection keeps slipping, more sales may create more pressure, not less.

3. Gross margin

Gross margin (the profit left after direct delivery costs) shows whether each sale is worth making. It should include the real cost of delivery: materials, labor, subcontractors, platform fees and the work of managing the client.

For a service business, a useful version is contribution margin (what a sale leaves after the costs it caused) per delivery hour. It shows whether your calendar is creating profit or only activity.

4. Fixed operating costs

Fixed costs are the bills that arrive whether sales are strong or weak: rent, core salaries, software, insurance, bookkeeping and basic operations.

Once you know them, you know your survival line. You can estimate the break-even point (where income covers all costs), how much cash reserve you need, and how much pressure a slow month creates.

5. Owner compensation and withdrawals

Owner pay is often the hidden number. Some owners underpay themselves and think the business is profitable. Others take irregular withdrawals when the balance looks high, then discover that VAT, tax or annual bills were not set aside.

A clear owner pay policy makes the picture more honest. It separates personal needs from operating cash and shows whether the model can support the person running it.

Use the five numbers to make decisions

These numbers should trigger action. If operating cash is low, delay nonessential spending. If cash collected is weak, go after receivables (money customers still owe you). If gross margin is thin, revisit pricing. If fixed costs are too high, change capacity or commitments. If owner withdrawals do not fit the model, reset owner pay.

For a broader dashboard, read financial KPIs for business owners. If your biggest worry is cash timing, start with cash flow versus profit.

If you run a startup, see how these numbers fit a full system in financial management for startups.

Turning these five numbers into a routine you actually use is the work of a financial consultant for small businesses.

After I finished a cosmetology course at a leading company, I was confused. I didn't know how to open a business, what to sell from home, or how to bring in clients. Since I reached out to Mobius, everything has changed. We built an organized plan with clear steps and no unnecessary risks. Today I see results, and I'm growing and developing every month.

When I finished a massage course, I imagined a different world. I found out it's a hard field, and financial stability isn't easy to find. When I came to Mobius, something changed. We started an organized process and built a business plan. Without Mobius? I probably would have given up. Today I believe in myself and in my own path.

And the paperwork, for anyone who wants to see that too.

Frequently asked questions

What are the first five numbers I should know?
Know operating cash, cash collected, gross margin, fixed operating costs, and owner compensation or withdrawals. Together they show what is available, what is profitable, and what the business must support.
Why is operating cash first?
Because survival depends on cash you can actually use. A bank balance that includes VAT, tax money, or future payroll is not the same as available operating cash.
Why track cash collected instead of only revenue?
Revenue can be invoiced long before the money arrives. Cash collected tells you whether customers are funding the business or the business is financing customers.
Why is gross margin one of the five?
Gross margin shows whether the work itself is worth selling. If margin is too low, growth may make the owner busier without making the business healthier.
Why include fixed operating costs?
Fixed costs are the bills that arrive even when sales slow down. Knowing them gives you the monthly survival line and helps calculate break-even.
Why include owner pay?
If the business only works when the owner earns nothing or withdraws randomly, the model is not clear. Owner compensation must be planned like a real business cost.
Should CAC be in the first five?
For businesses actively buying leads, yes. For a very early dashboard, track it after the owner can already see cash, margin, fixed costs, and owner withdrawals.
How often should I update the five numbers?
Check cash and collections weekly. Update margins, fixed costs, and owner compensation monthly. Review the model quarterly.
What should I do when one number looks bad?
Attach one decision to it. A bad receivables number needs collection action. A bad margin needs pricing or cost review. A bad fixed-cost number needs capacity or cost decisions.
Can a tool replace a financial diagnosis?
No. A tool can show the direction, but diagnosis connects the number to contracts, payment terms, pricing, tax obligations, delivery effort, and owner goals.
