Business Health Check:
10 Numbers Every SME Owner Should Review Each Month
When was the last time you gave your business a health check?
Most business owners know how much money is in the bank, but that's only one piece of the puzzle. The strongest businesses regularly monitor a handful of key financial metrics that provide a clearer picture of profitability, cash flow and long-term growth.
By reviewing these figures every month, you can spot trends earlier, identify potential issues before they become serious and make more informed business decisions.
At PJE Accountants & Advisors, we help clients move beyond simply preparing accounts. Using cloud accounting software, management reporting and our Virtual Finance Director service, we help business owners understand the numbers that really matter.
Here are the 10 metrics we recommend reviewing every month.
1. Gross Profit Margin
Gross profit margin shows how much money you make after covering the direct costs of providing your products or services.
A declining margin could indicate rising supplier costs, pricing that's too low or reduced efficiency.
Reviewing this figure regularly allows you to make pricing decisions before profits begin to suffer.
2. Net Profit Margin
While gross profit looks at direct costs, net profit tells you what's left after all business expenses have been paid.
It's one of the clearest indicators of how profitable your business really is.
Even if turnover is increasing, a falling net profit margin could suggest overheads are growing too quickly.
3. Debtor Days
How long does it take your customers to pay you?
Outstanding invoices are one of the biggest causes of cash flow problems for SMEs.
Keeping an eye on debtor days helps you identify slow-paying customers and improve your credit control processes.
A shorter payment cycle usually means healthier cash flow.
4. Creditor Days
Just as you monitor customer payments, it's important to understand how quickly you're paying suppliers.
Managing creditor days carefully helps maintain good supplier relationships while ensuring you're making the best use of your available cash.
The goal isn't necessarily to pay later. It's to pay strategically and consistently.
5. Cash Balance
Profit doesn't always equal cash.
A business can be profitable on paper while struggling to pay its bills.
Monitoring your cash balance alongside future commitments helps you avoid unexpected shortfalls and gives you confidence when planning investment or growth.
Using Xero's cash flow forecasting tools can make this much easier.
6. Revenue Growth
Is your business growing?
Comparing monthly revenue against previous months and the same period last year helps you understand whether you're moving in the right direction.
Steady, sustainable growth is often a better indicator of success than a single exceptional month.
7. VAT Liability
VAT bills can catch businesses off guard if they're not monitored regularly.
Reviewing your estimated VAT liability each month allows you to plan ahead and avoid cash flow surprises when your VAT return becomes due.
Setting money aside throughout the quarter can make payments much easier to manage.
8. Tax Provisions
Whether you're a sole trader or limited company, it's important to put money aside for future tax bills.
Many businesses accidentally spend money that will eventually need to be paid to HMRC.
Creating monthly tax provisions helps ensure funds are available when Corporation Tax or Self Assessment deadlines arrive.
9. Monthly Recurring Revenue (where applicable)
If your business earns regular monthly income through subscriptions, retainers or service contracts, Monthly Recurring Revenue (MRR) is a valuable performance indicator.
Tracking MRR helps you understand the stability of future income and makes forecasting much more reliable.
For service-based businesses, growing recurring revenue often leads to stronger cash flow and more predictable profits.
10. Average Customer Value
How much is each customer worth to your business?
Understanding your average customer value can help you make better decisions about pricing, marketing and customer retention.
If you know what a typical customer spends over time, you can make more informed decisions about how much you're prepared to invest in winning new business.
Turn Data into Better Decisions
The real value isn't simply collecting these numbers. It's understanding what they're telling you.
With modern cloud accounting software and reporting tools such as Syft Analytics, it's possible to see these KPIs in clear, visual dashboards rather than relying on spreadsheets. (Insert screenshots of Syft dashboards here to demonstrate management reporting.)
At PJE Accountants & Advisors, we work with businesses to turn financial information into practical insights through our Virtual Finance Director service and management reporting and advisory support.
Whether you're looking to improve profitability, strengthen cash flow or plan for future growth, understanding your numbers is the first step.
