The Customer Ledger

Are your customers worth what they cost to win?

Put in one average job and what you spend to win a customer. See what each customer is really worth to you, whether your leads pay for themselves, and what to change first.

Step 1

One average job

Prices and costs before GST.

How customers pay you

Example: an average service job, such as a switchboard or lighting upgrade. Type over the numbers with your own.

Not sure what a job really costs once the business is counted? Run three jobs through the Job Docket.

Step 2

Each customer, and your month

Where one customer's money goes

  • Materials
  • Labour
  • Payment fees
  • Winning the customer
  • Left over
  • What one customer pays you

Step 3

What to change first

Six changes, each tried on its own against your numbers, ranked by what they add to your month.

A price rise, faster jobs, more repeat work, cheaper leads or more of them. Most owners reach for more leads first. The list shows whether that's the right call for you.

How the sums work

Each one worked through with your numbers.

Left from each job

Price, less materials, labour and payment fees. Accountants call it contribution margin.

What a customer's worth

What's left from each job, times the jobs they book (or the months they stay). Often called lifetime value, or LTV.

What it costs to win one

Ads, lead fees, quoting time and discounts, divided by the new customers they brought in. Often called CAC.

Paid back after

The cost to win a customer, divided by what's left from each job or month.

New customers needed

What the business costs a month, divided by what each new customer leaves after the cost of winning them.

You now know what a customer is worth to you. The work is making every one of them pay.

Tamim490 works with owners who are great at the work and still doing all of it themselves.

Request a call with Mark

A planning tool, not financial advice. It treats every customer as average, assumes your monthly pace holds, and ignores tax, seasonality and the time between jobs. The 3 times and 12 month marks are common rules of thumb, and the right targets vary by trade. Check your numbers with your accountant.
