Xero Metric
Accounting
Vendor spend concentration measures what share of total operating spend goes to your top N suppliers. It quantifies supply-chain risk: the more concentrated your spend, the more exposed you are to any single vendor failing, raising prices, or being acquired.

Why vendor spend concentration matters for Xero users
Concentration is an under-tracked finance metric because most accounting tools hide it. Teams find out they are 40% dependent on one supplier only after that supplier raises a contract or misses a delivery. Watching it continuously lets procurement diversify before the concentration becomes a business risk.
Xero users with bills tagged to supplier contacts can compute this directly from the general ledger.
Understand and act on vendor spend concentration with KPI Tree
Query the Xero MCP `list-invoices` (bills) and `list-contacts` tools, or read the equivalent warehouse tables, and let KPI Tree rank suppliers by rolling 12-month spend. Track the share of total spend represented by the top 5 and top 10 suppliers as separate owned metrics.
Assign ownership to procurement or the COO and set alerts when the top 5 concentration rises above the business's risk threshold.

Expense-to-Revenue Ratio
AccountingMetric Definition
Expense-to-Revenue Ratio = Operating Expenses / Total Revenue
Expense-to-revenue ratio measures total operating expenses as a percentage of total revenue over the same period. It is a single-number summary of how operationally efficient the business is at each level of revenue.
Burn Rate
AccountingMetric Definition
Net Burn Rate = Monthly Cash Outflows − Monthly Cash Inflows
Burn rate measures the net cash consumed by the business each month, calculated as the difference between cash outflows and cash inflows. Gross burn is total monthly spend; net burn is gross burn minus any revenue collected.
Operating Cash Flow
AccountingMetric Definition
Operating cash flow measures the cash generated (or consumed) by the core trading activity of the business over a period. Unlike profit, it is not distorted by accruals, non-cash items, or timing of invoices.
Cash Runway
AccountingMetric Definition
Cash Runway (months) = Cash Balance / Monthly Net Burn
Cash runway measures how many months the business can continue operating at its current net burn rate before cash runs out. It is the single most important survival metric for any business spending more than it earns.
