The quickest way to more profit in most service businesses isn't a new product or a big change. It's selling the capacity you're already paying for: the empty slots in the diary, the van parked up, the room sitting empty. Once your fixed costs are covered, most of the money from that extra work goes straight to profit. Start by knowing your gross margin, then work out how much of your paid time is actually being billed.
What unused capacity looks like
Unused capacity is anything you've already paid for that isn't earning. For example:
- A van or vehicle that isn't out every working day
- Technicians or consultants with gaps in their diary
- A workspace or treatment room sitting empty for hours at a time
- Staff paid for time that isn't being sold
- Equipment that's rarely used but still being financed or insured
- A team member who could take on more responsibility or billable work
Why it's the fastest route to more profit
When your fixed costs are already covered, filling spare capacity adds very little to your overheads. You're making better use of what you've already paid for, so most of the extra revenue goes straight to the bottom line.
A new product, a new location or a new hire all cost money before they earn anything. Filling the gaps you already have doesn't.
The one number you need: gross margin
To know what extra work is really worth, you need your gross margin. It's what's left from each sale after the direct cost of delivering it, before overheads.
For example, if a job sells for £1,000 and the labour and materials cost £600, your gross margin is £400, or 40%.
If you don't know your gross margin, or haven't looked at it for a while, make it a priority this week.
Three questions to ask
Once you know your margin, ask yourself:
- What percentage of your working hours, or your team's, is actually billed?
- What would one more customer a week mean in profit? Using the example above, one more £1,000 job a week at a 40% margin adds about £400 a week, or roughly £20,000 a year, before any extra overheads.
- Are you making a real effort to fill the gaps, or coasting because the lights are still on?
How to fill the gaps
The quickest wins usually come from people who already know you: past customers and old enquiries. A simple follow-up system, such as the three-line email in how to follow up with leads, is often the cheapest way to fill a quiet week.
Unused capacity is quiet. Nobody complains about it, but it can bleed a business dry.
Frequently asked questions
What is unused capacity in a service business? Time, people, vehicles, space or equipment you already pay for that isn't being sold. Empty diary slots and idle vans are the most common.
Why does filling spare capacity increase profit so quickly? Because your fixed costs are already covered. Most of the money from the extra work goes straight to profit instead of into new overheads.
