In cost management, job costing is a method you use when your customers incur unique amounts of costs. Job costing assesses costs by the job and allows you to provide detailed price estimates based on the product constructed or service provided. For some businesses, nearly every customer job has different costs, and that's where job. Get reviews, pricing, and demos on the best mac accounting software. Prices starting from $9/month.

No two jobs are the same in construction, which makes estimating tough. Job costing is one of the best ways to develop an accurate budget and avoid blow-outs, but it's traditionally been hard work. Job costing software could make it more practical for you.
Job costing versus process costing
Construction and manufacturing projects are traditionally priced in one of two ways.
- Process costing
You identify the steps required to complete a job and assign an average cost to each one, based on past experience. Then you add the averages to produce an overall budget. - Job costing
You look at the job in detail and break down the specific labour and materials requirements. After calculating these costs, you add a charge to cover your overheads.
Process costing works best in industries with uniform costs like some forms of manufacturing. Job costing is more rigorous, involves fewer assumptions and – when done right – gives you more certainty.
It's particularly useful in construction, where there are so many variables from one job to the next. But it can be time-consuming and labour-intensive.
Breaking down job costing
Job costing only gives you a precise estimate if you're precise with your inputs. You need to think the project through, double-check the drawings, and visit the worksite to figure out how the job will unfold. Then you separate the project into major cost centres:
1. Labour
Start by working out how much it costs per day (or hour) to have your direct employees on the job. Multiply that rate by the time you expect the job to take.
Identify where you'll need subcontractors, then confirm their availability – you don't want to be waiting on them. Have the contractors estimate the job but be aware they may not be as precise as you. It pays to do your own calculations based on their hourly rate. You might want to build in some contingency to cover the tricky tasks that always seem to come up.
2. Material
Calculate a cost for direct materials like wood, steel and electrical wiring, then add indirect materials like fasteners and caulking. Make sure equipment hire is covered here too. You might also charge a margin on these materials to cover things like delivery and wastage.
3. Overheads
You'll need to charge an overhead to account for depreciation of equipment, and for other business expenses like office rental and administration. These costs don't directly relate to the job so this step is an approximation rather than a calculation. Many builders work out the overhead by adding 10 percent to each job – but each business is different. It's best to have an accountant help you find out how you should treat overheads.

Job costing software
Doing job-costing calculations used to require hours on spreadsheets and there was a lot of room for error. Job costing software streamlines the process and automates the calculations to make everything easier and faster.
It allows you to:
- Price jobs accurately
By working out the specific costs for each job, you'll have far more confidence in the final estimate. - Avoid customer conflict
An accurate upfront estimate reduces the risk of a nasty surprise when your customer gets the final bill. And the happier the customer, the greater your chance of getting repeat work and referrals. - Submit a timely estimate
Job costing used to take a lot longer than process costing. With job costing software, however, you just punch in the numbers – let the software do the maths – and your estimate is ready. - Calculate realistic profit margins
Job costing software makes it easy to add your markup and calculate your margin – so you stay competitive but profitable. - Track progress and costs in real time
As you work through the job, you can enter actual costs against estimated costs to see how the budget is looking. This will allow you to keep ahead of escalating costs and communicate with the client.
