POSVelo - Multi-Tenant SaaS POS with Inventory, HRM, and Payroll

POSVelo is a production-grade, multi-tenant SaaS Point of Sale (POS), Inventory, HRM and Payroll platform built for real businesses. With version 2.0, POSVelo evolves from a complete POS and inventory system into a full business operations platform combining fast checkout, real-time inventory, customer loyalty, multi-store management, human resource management, attendance, leave, payroll, and an employee self-service portal inside a single, unified codebase. Built with Next.js, React, Node.js, Express 5, PostgreSQL, Prisma and Socket.IO, fully typed in TypeScript from front to back. This is not a starter template it is a deployable, monetizable system engineered for retail shops, restaurants, wholesale distributors, service businesses and multi-branch chains from day one.

What Is New In Version 2.0

POSVelo 2.0 is a major release that transforms a POS and inventory product into a complete business management platform. Everything from version 1 is preserved all POS data, APIs and workflows remain fully intact while a comprehensive Human Resource Management, Payroll and Employee Self-Service suite has been added on top, alongside an expanded reporting engine, stronger security, and a true one-command Docker deployment.

• Full HRM Suite Employee management with encrypted personal data at rest, departments and designations, attendance tracking, leave management, holiday calendars, shift scheduling and rosters.
• Payroll Engine Reusable salary structures, per-employee assignment, salary advances with automatic recovery, payroll runs and per-employee payslips with decimal-precise calculations.
• Employee Self-Service Portal A dedicated staff portal where employees view and edit their profile, clock attendance, request shift swaps, apply for leave and download their own payslips and documents.
• Expanded Roles and Permissions New HR Manager, Accountant and Employee roles join the existing administrative hierarchy, with the permission set widened to cover every HR and payroll action.
• One-Command Docker Deployment A single top-level Docker Compose file builds and runs the database, cache, backend and frontend together, with database migrations applied automatically on startup.
• Versioned API A clean v2 API is introduced while v1 endpoints remain available and backward compatible, so existing integrations keep working without changes.

POSVelo adapts to your exact business workflow rather than forcing you into a fixed template. Every supported business type is treated as a first-class use case architected into the system from the ground up, never bolted on as an afterthought so a single counter and a fifty-location operation run on the same reliable platform. Manage every store, employee and transaction from one place, and add new locations as you grow without ever switching systems.

Every module ships complete with backend APIs, frontend interfaces, database models and real data relationships. These are working features, not “coming soon” placeholders.

• User Management and RBAC Role assignment, store scoping and granular permission control on every endpoint.

POS Terminal Technical Details

• Dual Scanner Support: USB and Bluetooth scanners are detected via inter-keystroke timing, and any phone can act as a wireless scanner through a Socket.IO relay with no app install and under 50ms latency.
• Split Payments: Cash, Card, Mobile Banking, Gift Card and Store Credit can be combined in a single transaction, with automatic change calculation and partial payments triggering accounts receivable tracking.
• Atomic, Race-Safe Checkout: Invoice creation, stock deduction, loyalty accrual and payments execute inside one atomic database transaction, so two cashiers scanning the last item at the same moment can never cause an oversell.

Inventory And Multi-Store Technical Details

• Inter-Store Transfers: Create, ship, receive or cancel, with source stock reserved on creation and the destination updated on receiving.
• Eight-Type Audit Trail: Sales, purchases, adjustments, transfers, damages, returns, corrections and initial stock every movement records actor, timestamp and reason.
• Low Stock Alerts: Per-product, per-store and per-variant thresholds with automatic alert generation.

Reports And Analytics Technical Details

• Profit Report: Revenue versus cost of goods sold, gross margin, expenses and net profit, with top products ranked by profit contribution and decimal-precise banker’s rounding.
• Sales Report: Revenue, tax, discounts and payment-method distribution, filterable by store, date range and daily, weekly or monthly aggregation.
• Cashier Report: Per-cashier transaction count, revenue, average sale value and shift summaries across all locations.

Attendance, Leave And Scheduling Technical Details

• Attendance: Real-time clock-in and clock-out, full attendance history and auditable correction requests for accurate records.
• Leave: Define policies, track balances and route requests through a clear approval workflow.
• Shifts and Rosters: Create shifts, assign weekly schedules and process shift-swap requests with manager approval.

Payroll And Employee Self-Service Technical Details

• Payroll Runs: Generate, review and finalise payroll by pay period, with reusable salary structures of earnings and deductions.
• Salary Advances: Issue advances that are automatically recovered from future payroll runs.
• Self-Service Access: Staff view shifts, clock attendance, apply for leave and download their own payslips strictly limited to their own data by backend enforcement.

Every advantage shown above is something you can confirm for yourself in the live demo before you buy. POSVelo pairs a modular, customizable architecture with the speed, security and reliability a growing business depends on, so the platform scales alongside your operation instead of becoming the bottleneck.

Enterprise Security Architecture

Security is built into every layer of POSVelo, with each layer designed to fail safe rather than fail open, so your data stays protected end to end.

• Multi-Tenant Isolation Every database query is automatically scoped through Prisma client extensions, using dual-layer scoping across direct models and child-via-parent relations to eliminate cross-tenant data leaks.
• Encrypted Personal Data Sensitive HR fields are encrypted at rest per tenant, protecting employee information at the storage layer.
• Refresh Token Theft Detection JWT rotation with automatic full-session revocation on reuse, so a stolen token instantly invalidates the entire device session.
• Role-Based Access Control Granular permission checks on every API endpoint across a hierarchical role structure, with the Super Admin role cryptographically pinned to the platform tenant.
• Redis Rate Limiting Per-IP and authentication throttling that fails closed when the cache is unavailable, leaving no bypass during an outage.
• Financial Precision Decimal arithmetic with banker’s rounding on all monetary computation, meeting accounting standards with no floating-point errors.
• Input Hardening Receipt HTML is sanitised before rendering to guard against cross-site scripting, with security headers and a content security policy retained throughout.
• Audit Trail Before-and-after JSON snapshots, actor identity, timestamp and client IP recorded on every critical operation.

Customer Loyalty And CRM

Turn one-time buyers into repeat customers with a complete CRM embedded inside the POS no third-party integrations required.

• Multi-Tier Loyalty Configurable earn and redeem rates, spend-based tier qualification, custom tier names and point multipliers.
• Customer Groups Wholesale, VIP and Staff groups, each with auto-discount percentages applied at checkout with no cashier action required.
• Unified Ledger All sales, credit payments, loyalty events and outstanding balances per customer in a single view.
• Gift Cards Unique codes, optional expiry and real-time balance tracking across every store.

Built-In SaaS Subscription System

POSVelo ships as a complete, monetizable SaaS platform with a four-tier billing system Free, Starter, Pro and Enterprise. Each plan controls store count, user accounts, product limits and feature access, and upgrade and downgrade logic is handled from the Super Admin panel. All pricing, features and tier names are fully customizable, so you can connect your payment gateway and begin charging customers without writing additional code.

Important Please Read Before Purchase

The full notice is shown in the image above. In short: POSVelo is a self-hosted script, and the one-time price covers the documented source code only. Running it in production may require paid third-party services your own hosting and PostgreSQL database, an optional payment gateway, and any external APIs such as media hosting or email and SMS delivery. Those are billed directly by their providers, not by us, and most offer free tiers suitable for testing. The item is sold as is for the features shown in the live demo; no third-party account, API key or paid plan is included with the purchase.
