How to clean up your numbers before you sell

Buyers look at the numbers first, and they price in what they can’t understand.

A buyer is paying for future profit. The numbers are their best evidence of what that profit will be. When the numbers are consistent and easy to follow, the conversation moves to growth and terms. When they’re messy, every question takes longer, confidence drops, and the risk shows up in the price or the deal terms.

This isn’t a valuation, and it isn’t accounting or tax advice. It’s the work of making the last two years clear and consistent, with your accountant, so a buyer can read them without you in the room.

The last 12 months, the last 24 by month, and what’s behind them.

• Trailing twelve months.

  Revenue and profit for the last 12 months, the first number most buyers ask for.

• Monthly results for the last 24 months.

  Month by month, so trends and seasonality are visible.

• Recurring vs one-time revenue.

  Repeat customers, contracts and subscriptions, separated from one-off sales.

• Customer concentration.

  Your top 20 customers and what share of revenue each represents.

• Cash in and cash out.

  The real timing of money, not just what the accounting says was earned.

The same numbers, pulled the same way, every month, in one place.

1. 01

   Start with the source systems.

   Your accounting software, bank, store or invoicing tool. Fix miscategorized transactions at the source, not in a spreadsheet on top.

2. 02

   Pull the same numbers the same way every month.

   Same categories, same cut-off date. Consistency matters more than detail.

3. 03

   Separate recurring from one-time.

   Tag revenue by type so a buyer can see what repeats.

4. 04

   Name the top customers.

   List them with their share of revenue, and how long each has been a customer.

5. 05

   Note one-time events.

   A big one-off order, a lawsuit, a move, a bad month with a clear cause. Write a one-line explanation for each.

6. 06

   Put it in one place.

   One file or folder a buyer’s team can work through without asking what a number means.

Do this with your accountant or bookkeeper. They own the books and the tax side. Your job is making sure the operations behind the numbers are consistent: orders entered one way, invoices sent on time, costs coded to the right place. If the numbers need a finance lead to sort out, that’s when a fractional CFO helps.

Owner dependence, customer concentration, consistency, and whether the business runs without you.

Clean numbers make those conversations shorter. If revenue is steady month to month, no single customer dominates, and the business kept performing when you stepped away, the numbers tell that story on their own.

  What to doClose each month on a fixed day, within a few weeks.

Clean numbers aren’t a project before a sale. They’re a monthly habit.

Close the books on a fixed day each month. Review the same handful of numbers every week on a KPI dashboard, and watch cash on a 13-week cash flow forecast. When this runs as a habit, getting ready for a buyer is a matter of printing what you already have. the free KPI dashboard template gives you a one-screen layout to start with.

Pull the trailing twelve months and the last 24 months by month. Separate recurring from one-time. Name your top customers. Put it in one place. That’s the start.

If you want the operations behind the numbers made consistent, that’s part of our exit planning work: clean monthly reporting built with your accountant, ready before a buyer asks.
