Separated access
Managers can record sales and expenses without seeing buying price, profit, stock value, or owner-only reports.
Security
Owner control without slowing managers down.
NumStack is designed for real shops where owners need privacy and managers need speed. Sensitive financial values stay owner-only while daily records continue.
Protection model
Email verification
Role-based access
Tenant-scoped records
Password reset codes
HTTPS production traffic
Audit-friendly activity
Verified accounts
New users verify email ownership, and temporary password flows require a fresh password after login.
Business isolation
Workspace data is tenant-scoped so products, sales, customers, debts, expenses, and reports stay separated.
Secure recovery
Forgot password and reset-required flows use email codes and clear recovery screens.
Operational audit
Platform admin views last login, IP signals, business status, broadcasts, and usage information.
Production posture
The public app is served over HTTPS with security headers and deployment-ready routing.
