Sales reporting with traceable totals — demonstration

Synthetic-data demonstration of converting sales rows into a product-level summary. Four sample order rows contain ten units with total revenue of EUR 82.50. Revenue reconciles by SKU: A01 EUR 37.50, A02 EUR 24.00, and A03 EUR 21.00.

The workflow calculates quantity times unit price, aggregates by SKU, and checks the summary against the source total. Deliverables for a scoped project can include an exportable report and validation notes. This is an Arratz demonstration using synthetic records, not a client commission.
