NTech
A business application for computer repair shop management, parts inventory tracking, and sales. Built with Go, it runs in the browser and requires no internet connection or external services.
⚠️ The project is under active development. It is not ready for production use.
About the Project
NTech is an internal application built for a specific user — a computer repair shop that, in addition to repairs, manages a parts inventory, sales of components and pre-built configurations, as well as client and supplier records.
The goal is simple: everything the repair shop needs to track is located in one place, without relying on Excel spreadsheets or paper records.
Features
Implemented
- Initial setup on first run (setup wizard)
- Database migration system
- User interface — sidebar navigation, theme system (dark/light), dashboard with statistics
- User login — server-side sessions, account locking
- Two-factor authentication (TOTP) — activation with a QR code; secret encrypted at rest (AES-256-GCM, key kept outside the database)
- Backup (one-time) codes for 2FA — generated on activation, stored as bcrypt hashes; a fallback to TOTP at login
- Brute-force protection — IP locking after 5 failed attempts within 15 minutes
- CSRF protection — double-submit cookie pattern, automatic token injection into all forms
- Security HTTP headers (CSP, X-Frame-Options, Referrer-Policy, nosniff...)
- Login attempt logging — history by user, IP, reason, date
- Users and roles — admin panel, user management
- Inventory — items, categories, filtering, critical stock levels
- Service orders — intake, status bar, costs, receipt
- Sales orders — items, calculation, receipt with company and client details
- Procurement — records of purchases from suppliers
- Sales price calculation on procurement — markup (global, per category, per item), landed costs (customs, shipping...) allocated across items, two-way markup↔price computation; respects VAT-payer status
- Price revaluation (nivelacija) — sales price changes with an audit trail (old→new, reason, source, user)
- Company profile and modules — features toggle based on company type and VAT-payer status
- VAT records (KIR/KPR) — books of issued and received invoices, auto-filled from sales and procurement
- VAT calculation per period + mapping to the PP-PDV form; imports (customs declaration) tracked in fields 006/106
- VAT rate code list
- Clients and suppliers — contact database
- Reminders — records with deadlines
- Reports — revenue overview, inventory status
- Settings — company name, address, Tax ID (PIB), logo; theme toggle
- Background images — login page and app, with blur, transparency and glass effect
- Personal theme and background — each user can set their own theme and background image
- Permission matrix (RBAC) — admin panel for permissions by role; enforced at the route level (both mutations and views) and in handlers
- Flash messages — one-time feedback after an action
- Automatic SQLite backup — with configurable number of retained copies; restore from a copy (safe, with no downtime)
- Charts — monthly revenue on reports (Chart.js)
- Structured logging —
log/slog(JSON in production, text in development); separate auth log in fail2ban format - Automated tests — unit and integration over a SQLite database (crypto, RBAC, login flows, form validators, reports)
Planned
- Fiscalization (ESIR/PFR) — specification in Project.md
- KPO book and double-entry bookkeeping (optional, later phase)
- PostgreSQL support (for multi-user environments)
- WebAuthn / Passkey login (database schema is already prepared)
- Notifications (email / WhatsApp) — deferred to a later phase
- Barcode scanning via camera — deferred to a later phase
