Powerful features that scale with your business
We enforce a zero-tolerance policy on unauthorized data access. Your business data is completely isolated, encrypted, and accessible only by you — no exceptions.
Hosting providers, associates, and development partners have absolutely no access to your production data.
Each account is fully isolated. You can only see and access your own data — always.
Passwords are hashed with bcrypt — never stored in plain text, never readable by anyone.
Sessions secured with JWT tokens in HttpOnly cookies — inaccessible to JavaScript or browser extensions.
Every action in your account is logged with timestamps — complete visibility and accountability.
All database queries use parameterized statements — protecting against injection attacks at the database level.
Invoice45 enforces a strict, non-negotiable policy: your business data is never accessed by anyone other than you. No hosting partners, no support staff, no developers — only automated security monitoring tools interact with the production environment, and every access attempt is logged and audited.
