Try MarginLens with a CSV or Excel export from your business. Your file is processed in your browser and is not uploaded to MarginLens.
This is an early preview, not a secure customer account or an automated live data feed. Avoid using highly sensitive data until you have reviewed the tool and your company's data policy.
1. Select a file
One row per invoice or credit-note line. Simple customer totals work too. You can use different column names — we'll help you map them. CSV, XLSX and XLS files supported.
Excel support uses a spreadsheet parser loaded from a public CDN; the spreadsheet contents remain in your browser. CSV works without that dependency.
2. Match your columns
Required: customer, date and sales. Map invoice number, product, quantity, sales rep, and category when available to unlock detailed reports. We calculate CVG from sales only.
3. Your sales overview
Processed locally
Monthly sales
Customer Value Groups (CVG)
Based on trailing 12-month sales; default annual bands: £5k, £15k, £40k, £80k.
Customer performance
The latest month is used for actual sales. Targets require 13 complete historical months before it, with the highest and four lowest removed. No history means no target. Customers with no sales in the latest month are included.

Calculated from your mapped data
All amounts are calculated from the uploaded rows. Product gaps are signals to investigate, not guaranteed lost revenue. No information is transmitted to MarginLens.
