Power BI for Trades and Professional Services: Solving the Reporting Problems Spreadsheets Can't

Trade businesses and professional services firms have almost nothing in common operationally - but they share one specific reporting problem: profitability is earned job by job, or matter by matter, and standard accounting reports were never built to show that. Here's what a dashboard actually needs to do for each.

Why Generic Reporting Falls Short for These Two Industries

A profit and loss statement tells you whether the business made money last month. It doesn't tell you which jobs were profitable and which ones quietly lost money, or which client matters are eating far more hours than they're billing for. That gap is exactly where job costing and utilisation dashboards earn their keep - and it's a different gap for a plumbing business than it is for an accounting firm.

Trade Businesses: Job Costing and Profitability per Job

For a trade business - electrical, plumbing, HVAC, building - the core question is simple to ask and surprisingly hard to answer without the right setup: did this job actually make money once materials, labour, and call-out time are accounted for, or did it just feel busy?

• Quoted versus actual cost - pulling the original quote alongside actual materials and labour logged against the job, so the variance is visible immediately rather than discovered at EOFY.
• Materials cost creep - tracking material costs against what was quoted, which matters more than ever with supplier pricing changing throughout a project.
• Profitability by job type or site - some categories of work are consistently more profitable than others. Without a dashboard, that pattern usually stays invisible because nobody has time to manually compare fifty jobs.
• Technician or crew productivity - billable hours logged versus hours actually paid, by person or by crew, without turning it into a surveillance exercise.
• Callback and warranty cost - jobs that generate repeat callouts quietly erode margin. Tracking this by job type or technician highlights where training or process fixes would pay off.

In practice, this dashboard pulls from your job management platform (ServiceM8, Simpro, Fergus, or similar) and your accounting platform, and lines the two up automatically. The owner or operations manager gets a live view of which jobs and which categories of work are actually carrying the business, instead of a gut feeling formed from the jobs that happened to be memorable.

Professional Services: Billable Utilisation, WIP, and Project Profitability

For law firms, accounting practices, engineering consultancies, and similar professional services businesses, time is the product - which makes the reporting problem different but just as costly to get wrong.

• Billable utilisation - the percentage of each staff member's available hours that's actually billable, versus admin, training, or business development time. This is usually the single biggest lever on firm profitability and the hardest number to see clearly without a dashboard.
• Work in progress (WIP) - hours and disbursements logged against a matter or project that haven't been invoiced yet. WIP that sits too long is cash the business has effectively already spent but not collected.
• Realisation rate - what was actually billed and collected against what was logged at standard rates. Write-offs and discounts erode this quietly, matter by matter, and rarely get noticed until someone adds it all up.
• Project or matter profitability - comparing the time and cost invested in a matter against the fee earned, which often reveals that certain client types or matter types are structurally unprofitable regardless of how busy the team looks.
• Aged WIP and aged debtors side by side - seeing both together highlights where billing delays are turning into collection problems.

This kind of dashboard typically connects practice management software (time and matter data) with the accounting platform (billing and collections), giving partners and practice managers a live view of utilisation and WIP rather than a monthly spreadsheet someone has to chase up from each fee earner.

It's also common for these dashboards to break utilisation and WIP down by team or by practice area, rather than only at the whole-of-firm level. A firm-wide utilisation figure can look perfectly healthy while one team is significantly under-utilised and another is dangerously overloaded, a pattern that stays invisible until the numbers are split out and looked at side by side.

What Makes These Builds Different from a Generic Sales Dashboard

The technical difference is mostly in how the data is modelled. A generic sales dashboard usually joins two or three clean tables. Job costing and WIP dashboards typically need to reconcile data from systems that weren't designed to talk to each other - a job management tool with its own idea of a "job," and an accounting platform with its own idea of a "customer" or "invoice." Getting the relationships right between these so the numbers actually reconcile is the bulk of the real work, more than the visual design of the dashboard itself.

What to Look at First

If you run a trade business, start with quoted-versus-actual cost on recent jobs - it's usually the fastest way to find where margin is leaking. If you run a professional services firm, start with billable utilisation by staff member - it's the number that most directly explains why a busy-looking firm can still have a disappointing month. Both are realistic to build as a first dashboard without committing to a larger reporting overhaul.
