Design the Business You Want at Month 24, Then Work Backward

Short Answer: Start with the business you want two years from now: its revenue, costs, team and the profit it pays you. Check that the profit covers your household target. Then work backward to what has to be true at month 12 and month 1: the customers, hires and equipment, and when each arrives. Lay that out month by month and you get the forecast, plus the one number most plans skip, how low your cash goes on the way.

The usual way to build projections is to take this month's revenue, add a growth rate, and roll it forward. The spreadsheet looks precise, but the growth rate is a guess, and nothing in it asks whether the business at the end pays for the life you want. Two years is long enough to build something real and short enough to plan in detail, so we start there.

Why Start at Month 24 Instead of Month 1?

A forecast built forward inherits every guess you make in the first row and multiplies it. A plan built backward starts from a destination you can judge: would this business, at this size, pay you enough? If the answer is no, you learn it before you've spent a dollar on the path. If the answer is yes, every earlier month has a job: close the distance to month 24.

It also changes the questions. "How fast will revenue grow?" has no good answer. "How many customers does the month-24 business need, and how many inquiries does that take?" does.

Step 1: Describe the Business at Month 24

Write down the business as it runs in its second year: what you sell and at what price, the gross margin on each line (what's left of each dollar after the direct cost of delivering it), the team, the equipment, and the fixed overhead. Use the run rate, meaning what a full year looks like at that size.

Step 2: Check It Against Your Profit Target

Your profit target is what the business has to earn before your pay so that your household gets what it needs after tax, plus what the business keeps for equipment and a reserve. (The method is in How Much Should I Pay Myself.) If the month-24 design falls short of the target, change the design now: prices, mix, team size.

Step 3: Work Backward to the Drivers

Break the design into things you can count: customers, visits, contracts, crew members, trucks. Then ask what each one requires. Customers require inquiries. Crew members require enough booked work to keep them busy. Equipment requires cash or a loan.

Step 4: Lay Out the Monthly Path

Place each driver on the calendar: when each hire starts, when the equipment arrives, how many customers you add each month. The result is a 24-month forecast where each month follows from decisions, not from a percentage.

Step 5: Find the Cash Low Point

Walk cash through the same 24 months. Early months carry the costs of the month-24 business (the hire, the truck) before its revenue shows up. The lowest balance tells you how much starting cash the plan needs, and how long your cash lasts if the ramp runs slow.

A Worked Example

Before a hypothetical landscaping company, Greenline Landscaping, was a full-time business, its owner worked as a crew lead and ran jobs on weekends. The weekend business made about $2,500 a month in profit. The owner's household needs $72,000 a year after tax, which takes about $92,000 of pre-tax profit, and the owner wants the business to keep another $20,000 a year for trucks and a winter reserve. The owner is taxed on that $20,000 as well, so the profit target is about $120,700.

Step 1: the month-24 design.

Step 2. $114,000 falls about $6,700 short of the $120,700 target. The household is covered, but the business would keep about $15,400 a year after tax instead of $20,000. The design needs one more change before the path is worth drawing: a mowing price increase or a shift toward commercial contracts that adds about $6,700 of profit.

Step 3: the drivers. Four crew members bringing in $520,000 means about $130,000 of revenue per crew member. Residential mowing is 30% of revenue, $156,000. At $55 a visit over a season of about 30 weeks, one weekly lawn brings in about $1,650 a year, so the month-24 business needs about 95 weekly lawns. Greenline's ads turn 25% of inquiries into customers at about $150 per new customer, so 95 lawns take about 380 inquiries and $14,250 of marketing. At 40 inquiries a month in season, that's roughly ten months of in-season ads, which means the ads have to start in the first spring, not the second.

Step 4: the path.

The second truck arrives when the third crew member does, financed with a loan that pays down $1,500 of principal a month. Profit reaches $92,000 a year, enough to cover the household after tax with nothing kept (about $7,670 a month), around month 12 and the full $114,000 run rate by month 24.

Step 5: the low point. In year one the business earns less than the household needs. The gap starts at $3,670 a month and closes by month 12, about $22,000 in total, which is why the owner planned to save about $40,000 before quitting (the full calculation is in Quitting Your Job). The averages also hide the seasons: Greenline earns most of its revenue from April to October, so the real low point lands in late winter, and a monthly forecast is what shows it.

What to Look For

• The gap or cushion at month 24. Greenline's design is about $6,700, or 6%, short of its target. A design that isn't at least about 10% over target tends to break on the first bad season.
• Drivers that take time to build. Customers, hires and equipment each have a lead time. If a driver needs ten months to fill, it has to start ten months before you need it.
• The cash low point, not the ending balance. A plan that ends with money in the bank can still hit zero in month 9.

What a Finance Consultant Would Do Next

A consultant working with Greenline's owner would test the month-24 design against a slower ramp (lawns filling in fifteen months instead of ten), look at whether a price increase on residential mowing closes the $6,700 gap, and time the second truck against the winter cash low so the loan payment doesn't start in the leanest month.

That analysis is what Occam's Model runs with your numbers. You describe the business at month 24, check it against what your household needs after tax, add the startup and growth investments, and shape the path month by month into a 24-month forecast that shows how long your starting cash lasts. When you need extra help, an expert can review it with you.

Common Questions

How far ahead should a small business forecast?
Two years in monthly detail is enough for most owner-run businesses. Beyond that, an annual view of years three to five is plenty, because the assumptions get too loose for monthly precision.

What if I don't know what my business will look like in two years?
Describe the version you'd be happy with, then test it. The design is a hypothesis. Working backward shows quickly whether it's reachable, and a design that fails the check is still useful because it tells you what has to change.

Do lenders accept projections built this way?
Lenders want monthly projections with stated assumptions, and a backward-built plan gives you both: every number traces to a driver you can explain.

Should I use my current business as the starting point?
Yes, if you have one. Your current revenue, costs and cash are month 0, and the plan becomes the distance between them and the month-24 design.
