Archiving & exposure

The backbone that gives value to receipts.

Nestor Stores centralises, structures and exposes transactional data at very high scale.

Nestor API · Access by customer or transaction
Via a Homer identifier or a receipt number, Nestor instantly returns the link to the WebArchive, WebReceipt or associated PDFs, through an intuitive, documented REST API.
Advanced filtering & intelligent tags
Isolate transactions by precise criteria (payment, product, time range, amount) via configurable tagging rules.
Intelligent webhook & real-time notifications
Nestor notifies the retailer or partners in real time whenever an event occurs on a receipt, based on precise rules: product, promotion, amount, Virgil alert or legal obligation.
Native GDPR governance
The retailer configures the retention period per data type. Nestor natively handles right-to-erasure, data restitution and the Homer consent portal.
