Discounts, Mates Rates and ‘Just This Once’: What It Does to Your Margins
You know how it goes.
A friend needs your service. They’re just getting started, money’s a bit tight, and they ask if you can do it for a bit less. You say yes, because of course you do, they’re your friend.
Then a referral comes in and the introducer quietly asks if you can do a little something for them too. Then a long-standing client mentions they’re going through a rough patch. Then someone in your network says they’d love to work with you but the rate is a stretch.
Before you know it, you’ve got a client list full of discounted work, a “just this once” that somehow became permanent, and a limited company that looks busy on paper but doesn’t quite add up in your bank account.
Sound familiar? It’s not a character flaw, it’s one of the most common margin-killers for service-based businesses.
Let’s talk about what’s actually happening when you say yes.
The real cost of a discount
Let’s do the numbers.
Say your standard monthly retainer is £800. A client asks for a discount, you agree on £640, it’s “only” £160 less, right?
Except over a 12-month engagement, that’s £1,920 you won’t see. Over three years of working with that client, it’s £5,760. And if three or four clients are on similar deals? That’s a significant chunk of revenue quietly disappearing every year.
That’s not a small favour. That’s a team member’s hours. That’s your own salary. That’s the investment in your business you keep putting off.
Discounts feel like generosity in the moment. But when they become a pattern, they become a structural problem, one that often doesn’t show up until you’re staring at your year-end figures wondering where it all went.
Mates rates: when relationships muddy the water
Working with people you know has real advantages; trust, ease, loyalty. But it also creates a dynamic that’s notoriously hard to manage.
When your client is also your friend, it becomes harder to:
Have a professional conversation about price increases
Hold firm on scope when they keep adding “small extras”
End the relationship if it stops being viable
Be taken seriously as a business owner rather than a favour-doer
Mates rates often start as a short-term arrangement but have a habit of becoming permanent. Their business grows. Your costs rise. Your team expands. But the rate stays stuck where it was three years ago because it feels awkward to bring up.
The relationship that felt like a perk can quietly become the client you dread looking at in your accounts.
‘Just this once’ — the phrase that keeps taking
The “just this once” jobs are perhaps the sneakiest margin-eaters of all.
They rarely feel like a big deal at that point in time. You squeeze in an extra task outside your usual scope. You spend an afternoon sorting out something that falls between the cracks. You help with an urgent request because the client’s stuck and you don’t want to let them down.
None of it gets charged. All of it costs you time.
Here’s the thing: one unbilled hour a week is over 50 hours a year. That’s more than a full working week given away for free, every year. For a small limited company, that’s significant. Multiply it across several clients and it becomes genuinely unsustainable.
And often, the client doesn’t even realise they’re asking. They don’t know what’s in scope. They just know you sorted it last time without a fuss, so they assumed it was part of the deal.
Why we do it — and why that’s worth understanding
Before this starts to feel like a telling-off, it’s worth being honest about why this happens.
Most service business owners who discount do it because they care. They want to help people. They worry about losing clients. They feel uncomfortable talking about money. They don’t want to come across as difficult or money-driven.
Some of it is also a quiet uncertainty about worth; whether the rate is really justified, whether the client might shop around, whether now is the right time to hold firm.
These are deeply human responses. But left unchecked, they lead to a business that runs on goodwill rather than profit.
You can be a warm, values-led business owner and charge properly for your work. The two are not in conflict.
What to do instead
1. Know your numbers before you price anything
If you don’t know what it costs you to deliver a piece of work; your time, your team, your overheads, your software, you can’t price it profitably. Start there.
Understanding your own cost base is the foundation of confident pricing. When you know that a certain job needs to be at a minimum price to be worth your while, “can you do it cheaper?” has a much clearer answer.
This is exactly where good bookkeeping pays for itself, when you can look at your actual figures and see clearly what’s working and what’s quietly draining you.
2. Separate the person from the price
If you want to support a friend or an early-stage business, there are ways to do that without discounting your core services. You might offer a smaller scope. A different package. A payment plan. Or simply be honest that you’re not the right fit for their current budget.
What you don’t have to do is take on work at a rate that doesn’t work for your business. Friendship and fair pricing can coexist.
3. Get crystal clear on your scope — and protect it
Every client relationship should have a clear written agreement on what’s included. When someone asks for something outside that scope, it doesn’t have to be a difficult conversation, it just means they need to add it to their package or pay separately.
This isn’t being difficult. It’s being professional. Clients who respect your work will expect it.
4. Build in regular price reviews
If you’re not reviewing your pricing at least annually, you’re almost certainly delivering more value for less in real terms than when you started. Your costs go up. Your skills grow. Your capacity is finite. Your pricing should reflect all of that.
A price increase doesn’t have to be a big deal. A straightforward email, delivered with good notice, is usually all it takes. Most established clients expect it.
5. Get comfortable with the conversation
This is the one people avoid most. But the ability to talk calmly and confidently about your pricing is one of the most important skills you can develop as a business owner.
You don’t have to be aggressive or apologetic about it. You just have to be clear. “This is what I charge for this” is a complete sentence. You don’t have to justify it at length.
Practice it. Say it out loud. It gets easier.
The bigger picture
Your margins matter, not just for the business, but for you.
When your margins are healthy, you can invest in better tools, bring on better clients, pay yourself properly, and build a company that gives you the flexibility and life you set it up for.
When your margins are quietly eroded by discounts, mates rates, and unbilled extras, you end up working harder for less, feeling stretched, and burning out, often without quite understanding why.
The service business owners who build genuinely sustainable companies are the ones who get clear on their value and hold it. Not rigidly. Not without empathy. But consistently.
Because you’re not doing anyone a favour by undercharging. Not your clients, who don’t learn to budget properly for quality support. And certainly not yourself.
