Upload a complete historical CSV or Excel export. Olasera requires at least 18 completed calendar months for reliable comparisons and historical targets.
Early-access test: please use fictional data only while we verify import recovery, access controls and reporting. Nothing is sent to the database until you choose Save.
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 is parsed in your browser using a public JavaScript dependency. Files are not stored as attachments; only mapped sales rows are saved when you confirm.
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.
Select any available month. Targets use the preceding 13 months, excluding the selected month.

Calculated from your mapped data

5. Save these transactions to your workspace
Before saving, we check the latest 18 completed calendar months, missing months, future dates and repeated files. Only fully validated replacements become active.
