The Deep Dive: Spotting Smart Management (and Bad Payers)
In the final part of our dashboard guide, we are looking at the "Management Metrics."
Anyone can grow revenue by spending a fortune. But can they generate a return on that spending? And do they treat their suppliers fairly? These four charts peel back the layers of the P&L to show you the quality of the decisions being made at the top.
Here is how to interpret the final set of charts on the Reportly dashboard.
1. Cost Breakdown (The P&L Stack)
What is it? This chart stacks up all the costs to show you exactly where the revenue goes.
Pink (Cost of Sales): Direct costs to make the product.
Yellow (Admin Expenses): Overheads like rent, marketing, and management salaries.
Purple (Net Profit): What is left over (or the loss, if it hangs below the line).
How to read the chart
The "Fat": Look at the yellow bars (Admin Expenses). If these are growing faster than the total height of the bar (Revenue), the company is becoming bloated with overheads.
The Bottom Line: In the example chart, notice how the purple bar (Profit) dips below the zero line in 2022/2023. This visualises a period where costs ate up every penny of revenue.
How to use this information
For Job Seekers: If you see "Admin Expenses" being cut (the yellow bar shrinking), it usually means redundancies or office downsizings are happening.
2. ROE % (Return on Equity)
What is it? Return on Equity measures how much profit the company generates for every pound invested by shareholders. It is the ultimate measure of efficiency for the owners.
How to read the chart
The Trend: You want to see a high, steady positive number.
The Volatility: In the example chart, ROE swings wildly from negative to +150%. This suggests a company that is either highly leveraged (using debt to boost returns) or has very unstable earnings.
How to use this information
For Investors: This is your primary metric. A high ROE means the company is a "wealth compounder."
For Employees: High ROE companies are efficient. They don't need to constantly raise funds to survive, which makes them more stable employers.
3. ROA % (Return on Assets)
What is it? Return on Assets answers a simple question: "How good is this company at using the stuff it owns to make money?" It looks at profit relative to total assets (cash, equipment, intellectual property).
How to read the chart
The Comparison: Asset-light companies (like software firms) should have very high ROA. Asset-heavy companies (like factories) will have lower ROA.
The Warning: If ROA is negative (as seen in 2021 on the chart), the company’s assets are effectively "lazy"—they are costing money rather than making it.
How to use this information
For Observers: This separates the "hype" from the "reality." A company might have a cool office and lots of equipment, but if their ROA is low, they aren't using those assets effectively.
4. Creditor Days
What is it? This measures the average number of days the company takes to pay its suppliers (creditors). It is a measure of "payment culture."
How to read the chart
The Number: In the UK, standard payment terms are often 30 days.
The Red Flag: Look at the chart—this company consistently takes 100 to 150 days to pay its bills. That is 3 to 5 months of delay.
How to use this information
For Suppliers/Freelancers: DO NOT IGNORE THIS CHART. If you are about to sign a contract with a company that has 150 Creditor Days, know that you will be waiting months for your money. You must negotiate better payment terms upfront or ask for a deposit.
For Job Seekers: Companies that delay paying suppliers are often managing a cash flow problem. If they struggle to pay vendors, payroll could be next.
