Key - 2026 Pricing, Features, Reviews & Alternatives

Key is a cloud-based commercial management system built for Argentine SMEs and retailers, including almacenes, kiosks, supermarkets, hardware stores, butcher shops, apparel stores, service businesses, and gyms. It consolidates point of sale, ARCA-compliant electronic invoicing, inventory control, and employee management into a single platform accessible via web browser, Android, and iOS.

Key connects directly to ARCA web services (WSAA and WSFE) using a digital certificate to issue electronic invoices (facturas A, B, and C). Invoice type selection and VAT calculation are handled automatically based on the fiscal status of both seller and customer, covering monotributistas and responsables inscriptos. CAE authorization is requested at the moment of sale confirmation, with a PDF generated immediately for printing or email delivery. When ARCA is unresponsive, an automatic retry mechanism attempts the pending voucher up to nine times without interrupting the sale. Additional fiscal features include automatic credit note generation on returns linked to the original invoice, sequential invoice numbering with gap control per point of sale, and ARCA tax registry lookup to auto-fill customer name, CUIT, and VAT status.

On the inventory side, Key ships with a pre-loaded catalog of over 175,000 Argentine products with barcodes and suggested prices, supporting USB and Bluetooth barcode scanners without driver installation. Stock updates on every sale or scan, with shrinkage tracking included. Shelf labels print in A4 PDF or thermal format. Sector-specific modules extend the platform for butcher shops (carcass breakdown with cost-per-cut and shrinkage tracking), apparel retailers, service businesses, and gyms. Key is available with a 7-day free trial covering full functionality, with no credit card required.
