How Does the Business Margin X-Ray Work?

Business Margin X-Ray is an advanced financial diagnostic framework enabling executives to discover real product and customer profitability. A frequent business pitfall is rising revenue that fails to translate into cash in the bank due to hidden loss-making transactions and unmonitored supplier price increases.

Gross Profit Formula

Gross Profit = Revenue (excl. VAT) - Weighted Average COGS

Measures the net operational margin available to cover overhead, salaries, and growth.

Gross Margin Formula

Gross Margin (%) = (Gross Profit / Revenue excl. VAT) × 100%

Shows how many cents of gross profit the business keeps from every euro in sales.

Why Margin Must Exclude VAT / Sales Tax

Value Added Tax (VAT) is a pass-through fiscal tax collected for tax authorities. If margins or markups are calculated on gross amounts including VAT, figures become distorted by up to 21%, creating an illusion of profit on loss-making orders. e-buhalteris.lt automatically calculates all unit costs and margins net of VAT.

Frequently Asked Questions (FAQ)

What is the difference between Weighted Average Cost and Last Purchase Price?

Last purchase price can be an outlier (one-off volume discount or high-cost rush order). The weighted average cost method (COGS) balances all inventory purchases by volume, protecting your business from erratic pricing errors.

How do I identify loss-making customers and products?

A loss-making sale occurs whenever the net discounted selling price falls below unit acquisition cost. Furthermore, high-maintenance clients whose gross margin is under 5–10% consume operational capacity and erode net bottom-line earnings.

Can I analyze my own company's CSV or Excel invoices?

Yes. Simply click the "Upload CSV" button and import your sales file with columns: Product, Customer, Quantity, Price, Cost, Discount. The intelligence engine recalculates all KPIs instantly in your browser.
