How Better Buying Can Add Thousands to a Tradesman’s Profit

Most tradesmen spend a lot of time trying to earn more money. Far fewer spend enough time looking at how they spend it.

Yet buying materials smarter can have a huge impact on profitability.

Think about it.

Saving just:

£50 per job

across:

100 jobs per year

adds an extra:

£5,000 profit.

And unlike increasing your prices, your customers never even notice.

If you’re constantly busy but still wondering where the money goes, improving the way you buy materials could be one of the easiest ways to improve your profits.

Why Procurement Matters More Than Most Tradesmen Realise

Many tradesmen focus heavily on:

• Winning work
• Quoting jobs
• Keeping customers happy

But they rarely think about procurement.

The reality is that materials are often one of the biggest costs on a job.

Even small savings can make a huge difference to your bottom line.

The best trades businesses don’t just price work well.

They buy well too.

Materials Are Usually One of Your Biggest Costs

On many jobs, materials can easily account for:

• 30%
• 40%
• Sometimes more than 50%

of the total contract value.

That means even a small improvement in buying can have a huge impact on profit.

For example:

A £10,000 job with £4,000 of materials.

Saving just 5% on those materials puts:

£200 straight onto your bottom line.

Now imagine you’re turning over £150,000 per year and spend £60,000 on materials.

A saving of just:

5%

would put an extra:

£3,000 profit into the business.

That’s money you don’t need to earn through extra work.

You don’t need to find another customer.

You don’t need to work longer hours.

You simply keep more of the money you’re already spending.

The Biggest Buying Mistakes Tradesmen Make

Some of the most common mistakes include:

• Buying from the nearest merchant every time.
• Never checking prices.
• Last-minute purchases.
• Too many merchant trips.
• Not reviewing invoices.
• Over-ordering materials.
• Under-ordering materials.
• Paying retail prices.

Individually these mistakes might seem small.

But over a year they can cost thousands of pounds.

Build Relationships With Suppliers

This is something good tradesmen understand.

Price lists are one thing.

Relationships are another.

A good relationship with your merchant can lead to:

• Better prices
• Faster service
• Improved credit terms
• Priority during shortages
• Helpful advice and recommendations

People often underestimate the value of having someone at the merchant who knows your business.

Sometimes a quick phone call can save you both time and money.

And don’t underestimate the value of being a good customer. Suppliers often go the extra mile for people they enjoy dealing with.

Good Suppliers Can Save You More Than Money

A good merchant relationship can also save:

• Time
• Stress
• Delays
• Callbacks

The best suppliers will often:

• Let you know about price increases.
• Recommend alternative products.
• Help source hard-to-find materials.
• Prioritise urgent deliveries.

In the trades, reliability is often worth as much as price.

Don’t Be Afraid to Negotiate

Many tradesmen simply accept the first price they’re given.

Big contractors negotiate.

Successful businesses negotiate.

And small trades businesses should too.

Ask questions such as:

• Is that your best price?
• Can you match this quote?
• Is there a trade discount available?
• Can I get a better rate if I buy more?

The worst they can say is no.

Ask for Better Terms Every Year

Many tradesmen open a trade account and then leave it untouched for years.

Meanwhile:

• Material prices change.
• Discounts change.
• Competitors negotiate better deals.

There is nothing wrong with asking your supplier to review your account once a year.

You might be surprised how much money is available simply by asking.

Use Trade Accounts Properly

Trade accounts are about more than convenience.

They can help with:

• Discounts
• Cash flow
• Easier record keeping
• Monthly statements
• Better purchasing history

However, don’t assume your prices are always competitive.

Review your pricing regularly.

Loyalty is important, but so is profitability.

Plan Jobs Better

Poor planning creates unnecessary costs.

For example:

• Extra trips to merchants.
• Emergency purchases.
• Labour waiting for materials.
• Additional fuel costs.
• Wasted time.

Good planning means:

• Ordering materials in advance.
• Checking quantities properly.
• Coordinating deliveries.
• Avoiding unnecessary trips.

Many tradesmen underestimate how much poor planning eats into their profit.

Deliveries Can Be Cheaper Than You Think

Many tradesmen automatically collect materials.

But deliveries can often:

• Save time.
• Reduce fuel costs.
• Improve productivity.
• Keep labour on site.

Sometimes paying £30 for delivery can save significantly more in labour costs.

The cheapest option isn’t always the one with the lowest invoice.

Don’t Ignore Credit Terms

Buying materials on account can be extremely helpful.

Used properly, credit terms can:

• Improve cash flow.
• Allow you to collect payment before paying suppliers.
• Reduce financial pressure during large jobs.

But be careful.

Credit terms should improve cash flow, not become an excuse for overspending.

Check Every Invoice

Pricing errors happen.

Discounts are missed.

Items are charged incorrectly.

Delivery charges appear unexpectedly.

Many businesses simply pay invoices without checking them.

Over the course of a year, those mistakes can add up to significant amounts of money.

Always review:

• Prices
• Quantities
• Discounts
• Delivery charges
• Credit notes

It’s boring work.

But it protects your profits.

Watch Out for Price Increases

Material prices can move surprisingly quickly.

Many tradesmen simply assume today’s prices are the same as six months ago.

They’re often not.

If you regularly buy:

• Cable
• Timber
• Pipework
• Fixings
• Consumables

even small increases can quietly eat away at your margins.

Good businesses keep an eye on pricing trends and review their quotes regularly.

I know it’s fuel, but the principle is exactly the same.

Standardise Materials Where Possible

Successful businesses often standardise the products they use.

This can lead to:

• Better buying prices.
• Less wasted stock.
• Easier ordering.
• Better product knowledge.
• Faster installations.

Changing products constantly can increase costs and create unnecessary complications.

Don’t Tie Up Money in Stock You Don’t Need

Buying in bulk can save money.

But it can also create problems.

Too much stock means:

• Cash tied up on shelves.
• Materials getting damaged.
• Products becoming obsolete.
• Money that could be used elsewhere.

Good procurement is about buying efficiently, not simply buying more.

Consider the Total Cost, Not Just the Purchase Price

The cheapest product isn’t always the cheapest option.

Ask yourself:

• Will it last?
• Will it create callbacks?
• Is it easy to install?
• Is it reliable?
• Will it save labour?

Sometimes spending an extra £50 on better materials can save hundreds of pounds later.

Good businesses focus on:

Total cost.

Not simply:

Purchase price.

Avoid Buying Purely on Price

Cheaper isn’t always better.

Poor-quality materials can lead to:

• Callbacks
• Warranty issues
• Delays
• Customer complaints

Sometimes paying slightly more for better materials actually improves profitability.

Because avoiding one callback can save far more money than the initial saving.

The Hidden Cost of Too Many Merchant Trips

This is one of the biggest hidden costs in the trades.

A quick trip to the merchant isn’t just the cost of the materials.

It’s also:

• Fuel
• Van wear and tear
• Time
• Labour
• Lost productivity

Five extra merchant trips per week soon become:

• Hundreds of hours per year
• Thousands of pounds in hidden costs

Procurement Is Often Easier Than Raising Prices

Many tradesmen are nervous about increasing their prices.

But improving procurement is different.

Your customer never sees it.

They don’t know:

• Which merchant you used.
• Whether you negotiated a discount.
• How efficiently you bought materials.

It’s one of the few ways you can improve profitability without changing your prices at all.

The Real Profit Opportunity

Let’s say smarter buying saves:

£50 per job.

Across:

100 jobs per year.

That’s:

£5,000 extra profit.

To make an extra £5,000 through sales alone, many tradesmen would need to complete a significant amount of additional work.

Buying smarter is often one of the easiest ways to increase profit without:

• Working longer hours.
• Increasing prices.
• Taking on more stress.

Good procurement isn’t about being cheap.

It’s about:

• Planning ahead.
• Building relationships.
• Negotiating properly.
• Buying efficiently.
• Protecting your cash flow.
• Understanding your true costs.

The best trades businesses treat purchasing as a skill.

Because it is.

The reality is that many profitable businesses don’t necessarily charge more than their competitors.

They simply buy better, plan better and waste less money.
