About KYEASY
Software development is the core business of KYEASY. We transform our clients' business ideas into stable, user-friendly, maintainable, and continuously evolving software products.
Our team brings together business analysis, product strategy, UI/UX, systems architecture, front-end, back-end and mobile development, testing, security, and cloud operations. We can take a requirement or prototype through production launch and every iteration that follows.
We serve retail, food service, local services, e-commerce, and growth-oriented companies, delivering corporate websites, management platforms, SaaS systems, mobile apps, API integrations, and blockchain applications, while also providing functional documentation, test reports, and code audit reports.

French POS Compliance by Design
KYEASY incorporates the requirements of Article 286 I-3° bis of the French General Tax Code (CGI) into the design, development, and testing of its POS module. The applicable scope must be confirmed against the merchant’s tax status, customer type, and actual payment flow.
Retain original transaction, cancellation, correction, and refund records, and generate a continuous audit trail.
Prevent covert modifications or deletions through access control, integrity checks, and operation logs.
Retain transaction-by-transaction data and daily, monthly, and annual closing results, supporting inspections within the prescribed period.
Generate archive batches with integrity assurance and readable exports, supporting tax inspections.
At delivery, the software version, enabled modules, and scope covered by the supporting documents must be verified. This website describes design objectives for compliance only. Unless a valid certificate or supporting document is provided, KYEASY does not claim NF525, LNE, or any other third-party certification.
