In a regulated business, the question is never only "what does the software do?" It is "what can you prove, to whom, years later." Zeflash is built so the answer does not depend on anyone remembering to be careful.
Each customer’s data lives in its own dedicated database; within a customer, each company sits in its own compartment, and files live in per-customer storage. Which customer a request belongs to is taken from the signed login, never from anything a caller can type.
Roughly seventy business tables are stamped by the database itself with who created and last changed each row. A service acting on behalf of a person records the person; system writes carry a distinct marker.
A rejected inspection quarantining a batch, scrapping a serialised unit, opening a non-conformance, escalating to a corrective action — recorded append-only across modules, so any outcome traces back to its origin. Entries are never edited or deleted.
Permissions deny everything by default. Separation of duties is enforced for quality work. The switches that turn regulatory controls on or off cannot be flipped by an ordinary settings admin — only the owner, or someone explicitly granted that single switch. Nobody can grant a permission they do not hold.
Logins are signed with a private key only the core holds. Refresh tokens are single-use with automatic theft detection. Any session is revocable immediately, with who and why recorded, and takes effect group-wide within 30 seconds.
Certificates are numbered per financial year, watermarked, digitally fingerprinted and version-chained. A reissue states its reason, the previous version is watermarked Superseded, and a one-click check re-verifies the whole chain for an auditor.
The fastest way through this conversation is your auditor’s actual questions.
