A healthy overall profit can hide a business problem sitting right underneath it: some jobs are quietly making you good money, and others are barely breaking even — or losing money — once you actually account for everything that went into them. Without breaking income and expenses down by job, there’s no way to tell which is which. That’s exactly what Projects is for.
Step 1: Create a project for each job or client engagement
Whether it’s a single contract, a specific client you do recurring work for, or a distinct piece of work with its own start and end, give it its own project. A project is nothing more than a label everything related to that job gets tagged with — setting one up takes seconds and doesn’t require anything more than a name.
Step 2: Link income and expenses to the project as you go
When you record an invoice for that client, or an expense that belongs specifically to that job — materials, a subcontractor, transport for that one delivery — tag it to the project. This is the step that actually makes the numbers meaningful later, and it costs you nothing extra: you were recording that transaction anyway, tagging it just takes one more tap.
Step 3: Check the project’s own profit and loss anytime
Open the project and you’ll see its own income, its own expenses, and what’s actually left over — the real profitability of that specific job, not blended into everything else you’re doing. This is where the picture often looks different from what the overall business numbers suggested: a job that felt busy and important can turn out to have thin margins once its own costs are isolated, while a quieter one turns out to be your most profitable work.
A practical tip: not every transaction needs a project
General overhead — rent, your own salary, software subscriptions — usually isn’t tied to one specific job, and trying to force it into a project rarely tells you anything useful. Reserve projects for costs and income that genuinely belong to a specific piece of work; the picture stays sharper that way, rather than getting diluted by things every job would have had to share regardless.
Where this matters most: service and contract-based businesses
If you quote fixed prices for jobs — a construction contract, an events booking, a batch production run, a consulting engagement — this is the single clearest way to find out afterward whether the quote actually held up against what the job really cost you to deliver. Businesses that do this regularly tend to get noticeably better at quoting future jobs, simply because they’re no longer guessing.
Getting started
Pick one job you’re currently working on — ideally one you’re curious about the real margin on — and create a project for it today. Tag its income and expenses as they happen from here on, and in a few weeks you’ll have a genuinely useful answer to a question most small businesses never actually check: is this specific job worth what it’s costing you to do it?
