Pricing is where most bespoke manufacturers lose money without realising it. Not on every job - but on enough jobs that the workshop is always busy yet never as profitable as it should be. The problem isn't a lack of work. It's a lack of visibility into what each job actually costs.
If you've ever finished a job and thought "we barely made anything on that one," or worse, suspected you actually lost money but couldn't prove it, this article is for you. We'll walk through the most common pricing mistakes, a practical job costing framework, and how to start tracking actual costs against your estimates - so you can price with confidence and protect your margins on every job.

The 5 Pricing Mistakes That Eat Your Margins
Before we get to the formula, let's look at the mistakes that cause most of the damage. These aren't theoretical - they're the patterns we see in workshops every week:
Underestimating materials
You quote for the boards you need, but you forget the waste. Offcuts that can't be reused. Edging tape. Hinges, drawer runners, handles. Finishing materials - lacquer, oil, stain. Adhesives. Screws and fixings. Packaging materials for delivery. On a typical kitchen job, these "forgotten" items can add 15-25% to your material costs. If you're not accounting for them in your quote, you're giving that margin away.
Not tracking actual labour time
You estimate 8 hours for a wardrobe build. Your joiner actually spends 12 - but nobody records it, so you never know. Next time, you quote 8 hours again. And the time after that. This is the single most common pricing leak in bespoke workshops. Without tracking actual hours against estimates, you're guessing - and most workshops consistently underestimate labour by 20-40%.
Ignoring overhead
Your rent doesn't stop when the workshop is quiet. Neither do machinery lease payments, insurance premiums, utility bills, vehicle costs, software subscriptions, or your accountant's fees. These costs need to be spread across every job - but many workshops price only for materials and labour, treating overhead as "just the cost of being in business." It is the cost of being in business, and every job needs to carry its share.
Using last year's material prices
Timber and board prices change quarterly - sometimes more often. If your quoting process is based on a price list you put together six months ago, you could be 10-15% below current costs on every quote. Over a year, that adds up to thousands in lost margin.
Not accounting for callbacks and rework
Every callback eats margin from a future job. The time spent returning to site, the replacement materials, the disrupted production schedule - none of this appears in your original job costing. If you're averaging even one callback per month, you need to factor that cost across all jobs. A 2% rework allowance is realistic for most bespoke workshops.
The Compound Effect
Each of these mistakes might only cost you 5-10% on a single job. But stack them together and you're looking at 25-40% of your margin disappearing. On a £5,000 job, that's £1,250-2,000 in profit you never see. Multiply that across 200 jobs a year and the numbers become alarming.
A Simple Job Costing Framework
Here's a straightforward formula that covers the essentials. It's not perfect for every situation, but it's a solid starting point that most workshops can implement immediately:
The Job Costing Formula
Materials (inc. waste) + Direct Labour (hours x rate) + Overhead Allocation + Target Margin = Selling Price
Let's walk through each component with realistic numbers.
1. Materials (Including Waste Factor)
Start with the raw material cost for the job. For board materials, calculate the area you need in square metres and multiply by the cost per sheet. A standard 2440 x 1220mm sheet of 18mm melamine-faced chipboard currently runs around £36-42 (prices fluctuate - always check with your supplier for current rates), while quality plywood is £45-70 per sheet. Hardwoods vary wildly - oak at £800-1,200 per cubic metre, walnut at £1,500+.
Then add your waste factor. For board materials, 15% is the industry standard. For solid timber, use 20-25% depending on grade and how irregular the stock is. This isn't padding - it's reality. Between saw kerfs, defects, grain matching, and pieces that don't nest efficiently, you will use more material than the finished product contains.
Don't forget consumables: edging tape (£0.30-1.50/m depending on type), adhesives, abrasives, finishing materials, fixings, and hardware. On a fitted wardrobe, hardware alone - hinges, runners, handles, hanging rails - can be £150-300.
2. Direct Labour
Break your labour into categories with different rates. A skilled bench joiner in the UK typically costs £18-25 per hour (total employment cost, not just salary) - the Construction Industry Training Board (CITB) publishes useful benchmarks on skilled trade rates. Assembly and finishing work runs £14-18 per hour. Installation on site can be £20-28 per hour when you factor in travel time and the higher skill level required.
Be honest about how long each stage takes. A common mistake is to estimate the time for cutting and machining but forget the setup time, the time spent reading drawings, dry-fitting components, and cleaning up between jobs. For a bespoke kitchen, realistic labour breakdown might look like this:
Example: Bespoke Kitchen (12 Units)
3. Overhead Allocation
This is the part most workshops skip - and it's the part that makes the difference between thinking you're profitable and actually being profitable. Add up your total monthly overheads: rent, rates, utilities, insurance, machinery leases or depreciation, vehicle costs, software, phone bills, accountancy fees, consumable tools, and any other fixed costs.
For a typical 4-person workshop, monthly overheads might look like this: rent £1,500, utilities £400, insurance £250, machinery costs £600, vehicles £500, other £350. That's £3,600 per month.
Now divide by your productive hours. Four workers at 37.5 hours per week, but realistically only 75% of that time is directly productive (the rest is setup, cleaning, breaks, admin). That gives you roughly 112 productive hours per week, or 487 per month. Your overhead rate: £3,600 / 487 = £7.40 per productive hour.
For the kitchen example above with 47 direct labour hours, the overhead allocation would be 47 x £7.40 = £348.
4. Target Margin
Once you've covered materials, labour, and overhead, you need your profit margin. For bespoke furniture and other made-to-order manufacturing, typical target margins range from 25% to 40% depending on the complexity of the work, the level of customisation, and your market position. Higher-end work with specialist skills (curved joinery, complex veneering, heritage restoration) commands higher margins - often 35-45%.
Important: margin should be calculated on the selling price, not marked up on cost. If your total cost is £3,000 and you want a 30% margin, the selling price is £3,000 / 0.70 = £4,286 - not £3,000 x 1.30 = £3,900. The difference matters: the first gives you a true 30% margin (£1,286 / £4,286), while the second gives you only 23% (£900 / £3,900). And remember, if your turnover is above the threshold, you'll also need to account for VAT in your pricing calculations.
Putting It All Together: Kitchen Example
Materials (inc. 15% waste): £1,850. Direct labour: £978. Overhead allocation: £348. Total cost: £3,176. At a 30% target margin: £3,176 / 0.70 = Selling price: £4,537. Your gross profit: £1,361. Without the overhead allocation and waste factor, you'd have quoted £3,540 - barely covering your true costs.
Tracking Actual vs Estimated Costs
Having a good formula is only half the battle. The other half is knowing whether your estimates are actually accurate - and the only way to know that is to compare what you quoted against what the job actually cost. Most workshops never do this. They quote a job, build it, invoice it, and move on. The estimate is never revisited.
This is how pricing errors compound over years. If you consistently underestimate labour by 20%, you'll make that same mistake on every job until someone actually measures the gap. The discipline of recording actual time and materials per job is the single most valuable habit you can build in your workshop.
Example: Job Cost Variance Report
A £226 overrun on one job doesn't sound catastrophic. But if you're making that same 10% estimating error on every job, and you complete 200 jobs a year at an average value of £3,000, that's £60,000 in revenue where you've underestimated costs by 10% - meaning roughly £6,000 per year in lost profit. That's often the difference between a workshop that's scraping by and one that's thriving.
The fix is simple but requires discipline: record actual materials used and actual hours worked on every job. At the end of each job, spend five minutes comparing actuals to estimates. Over time, you'll see patterns - maybe your assembly estimates are always accurate but your finishing estimates are consistently 30% low. That's actionable intelligence you can use to improve every future quote.
When Spreadsheet Pricing Breaks Down
Many workshops start with a spreadsheet-based pricing system and it works fine - when you're doing 2-3 jobs per week. You can manually calculate materials, estimate labour from experience, and keep a rough mental track of how jobs are going.
But spreadsheet pricing breaks down predictably as you grow:
20+ jobs in various stages
You can't see at a glance which jobs are profitable and which are overrunning. By the time you realise a job has gone over budget, it's already shipped and invoiced.
No automatic material cost updates
Your spreadsheet price list is only as current as the last time someone manually updated it. If board prices went up last month and nobody changed the spreadsheet, every quote since then has been too low.
Can't aggregate data across jobs
You might know that one specific job went over budget, but you can't easily answer questions like: "Are our fitted wardrobe jobs consistently less profitable than kitchen jobs?" or "Which customer type gives us the best margins?" Spotting patterns across hundreds of jobs in a spreadsheet is practically impossible.
No real-time margin visibility
With spreadsheets, you find out a job was unprofitable after it's done. With proper software, you can see the margin while the job is in production - and take action before it's too late. That's the difference between a post-mortem and a course correction.

How Software Automates Job Costing
The framework above works whether you use a spreadsheet, a notebook, or dedicated software. But software makes it dramatically easier - and more importantly, it makes it automatic so it actually gets done consistently:
Materials calculated from order specifications
Enter the dimensions and specifications once. The software calculates board requirements, applies waste factors, adds hardware and consumables, and costs everything at current prices. No manual calculations, no forgotten items.
Labour tracked automatically via worker app
Workers log their time against jobs from their phones. No paper timesheets, no guessing at the end of the week. You get accurate, real-time labour data for every job without any additional admin.
Overhead allocated per job based on production time
Set your overhead rate once and the software applies it automatically to every job based on the hours logged. No mental arithmetic, no forgotten allocations.
Real-time margin dashboard shows profitability per job
See exactly where every job stands financially while it's still in production. If a job starts to overrun, you know immediately - not two weeks after it shipped. Explore how this works with CutFlow's profitability features.
Historical data reveals pricing patterns
After six months of data, the software can tell you that your kitchen jobs average 32% margin while your wardrobe jobs average only 18%. That your installation estimates are consistently 25% too low. That one particular type of job always overruns. This is the intelligence that transforms your pricing.
Practical Steps to Improve Your Pricing Today
You don't need software to start improving your pricing. Here are five things you can do this week, with whatever tools you already have:
Calculate your true overhead rate this week
Add up every fixed cost your workshop incurs per month. Divide by your total productive hours. Write that number down and stick it to your monitor. If you're not adding at least that amount per labour hour to every job, you're subsidising your customers from your own pocket.
Add a waste factor to every materials estimate
If you're not already doing this, start now. 15% for board materials, 20-25% for solid timber. It feels like you're inflating the price, but you're not - you're simply being accurate about what the job will actually consume.
Start tracking actual hours per job
Even on paper. Even roughly. A simple sheet on the workshop wall where each joiner writes the job number and hours spent each day. It doesn't need to be perfect - even approximate data is infinitely better than no data. After a month, you'll start seeing where your estimates are off.
Review your 5 most recent completed jobs against estimates
Go back to the last 5 jobs you completed. For each one, try to work out what the materials actually cost and how many hours were actually spent. Compare that to what you quoted. Even if the numbers are rough, you'll likely find at least one job where you significantly underestimated - and you'll know what to fix. See our guide on calculating the true cost of manual processes for more on this.
Consider software when manual tracking becomes unsustainable
Paper time tracking and manual cost comparisons work for a while. But when you have 15-20 jobs running simultaneously and 6+ workers, the admin overhead of manual tracking starts to outweigh the benefit. That's when purpose-built software pays for itself - not just in time saved, but in the pricing accuracy it delivers.
Pricing bespoke manufacturing isn't rocket science, but it does require discipline and data. The workshops that price well aren't the ones with the fanciest tools - they're the ones that measure, compare, and improve with every job. Start with the basics, build the habit of tracking actuals against estimates, and your margins will follow.
