NexoPOS is a point-of-sale platform that runs a whole shop from the browser, covering the till, the stockroom, the customer book, and the day-end numbers in one place. Cashiers ring up sales on a touch-friendly register screen, take cash or card payments, print receipts, and process refunds without leaving the same view. Every sale draws down inventory automatically, and procurement flows record what arrived, from which supplier, and at what cost. Low-stock warnings and a full stock history help owners reorder before shelves go empty. Products carry categories, units, and tax rules, and barcode plus scale barcode support keeps weighed goods moving at the checkout. Regulars earn rewards, join customer groups, and redeem coupons at the till. Managers open and close registers, assign roles and permissions to staff, and review an activity trail for every sensitive action. Reports break down sales, costs, and stock value per period, giving a small shop the numbers usually reserved for chain headquarters. Owners extend the core with installable modules for restaurants, multiple stores, rentals, and bookings, added from inside the dashboard instead of by editing code. The same installation serves a single boutique today and a growing chain tomorrow, since registers, stores, and staff all live in one database.

OrderRestro runs an entire restaurant from one server on the premises: tills take orders, the kitchen watches tickets arrive, tables fill and clear, and the books close at night, all without a subscription, and it keeps working when the internet drops. Billing covers dine-in and takeaway with merged bills, discounts, gift cards, tips, and refunds, and it taxes under India GST, US sales tax, EU VAT, or Spanish IVA, with UPI QR payments confirmed by an audible alert. A visual floor plan follows every table while reservations and a waitlist manage the door, and guests scan a table QR code to order, add modifiers, call the waiter, or request the bill. Kitchen tickets route to the right station on the display system with preparation tracking, and the menu supports modifier groups, combos, seasonal menus, and scheduled availability. Ingredient inventory with recipe costing, purchase orders, goods receiving, and waste tracking keeps food costs honest, and accounting closes cash nightly with variance checks, profit and loss, a balance sheet, and bank reconciliation. Staff clock in and out, shifts are scheduled with clash checks, payroll comes from clocked hours, and loyalty points, memberships, coupons, and happy-hour campaigns keep regulars returning. Delivery runs on zones with fees, minimums, and driver assignment, chains switch branches and transfer stock between them, and eighteen reports export to print, CSV, Excel, or PDF.

Roughly 40 integrated business apps forming a full ERP: Odoo's open-source suite runs companies end to end. The Community Edition, licensed LGPL-3.0, ships roughly 40 apps covering CRM, sales, invoicing, basic accounting (journals, chart of accounts, taxes, reconciliation), inventory and warehouse management with multi-step routes, manufacturing with BOMs and work orders, purchasing, project management, timesheets, HR, a website builder, and eCommerce. Each app works standalone, but they share one PostgreSQL database and one data model, so a confirmed sale updates stock, triggers procurement, and posts invoices without integration glue. The modular design means you enable only the apps you need and extend with 40,000+ community modules from the Odoo app store covering nearly any vertical requirement. Inventory supports multi-warehouse stock, reordering rules, and lot and serial tracking with barcode-ready operations; manufacturing ties BOMs, work orders, and work-center routing directly to sales demand and stock levels; and the website builder sells straight from your product catalog with payment provider integrations. You can start with just CRM and invoicing on day one and switch on inventory or eCommerce later - new apps integrate with existing data instantly because the schema is shared. The server is Python with an XML/JavaScript view layer, and because data lives in plain PostgreSQL there is no proprietary format: you can query, back up, migrate, and extend business data directly, with unlimited users and no per-seat licensing - where enterprise ERP pricing is per user per month, headcount here costs nothing.

With 7,400+ GitHub stars, 280+ contributors, and 99 releases spanning 15 years of active development since 2011, Dolibarr is the modular ERP and CRM platform that scales from freelancers tracking invoices to manufacturing companies managing full production workflows — all within a single PHP application requiring only a web server and database.

With over 37,800 GitHub stars and active development since its first release in 2008, ERPNext is the most-starred open-source ERP system — delivering accounting, inventory management, manufacturing, CRM, project tracking, asset management, HR, and point-of-sale capabilities through a unified web interface built on the Frappe Framework's metadata-driven architecture. The accounting module handles multi-company consolidation, multi-currency transactions, tax templates for GST and VAT, bank reconciliation, and automated journal entries with real-time profit and loss, balance sheet, and cash flow reporting. Manufacturing covers production planning with multi-level bill of materials, work order scheduling, capacity planning, subcontracting, and quality inspection at each production stage. Inventory tracks stock across multiple warehouses with batch and serial number tracing, automatic reorder levels, landed cost calculations, and perpetual inventory valuation using FIFO or moving average methods. The CRM module manages leads, opportunities, and customer communication with email integration, while project management tracks tasks, timesheets, and Gantt-based scheduling with budget controls. Custom applications extend functionality through the Frappe ecosystem without forking the core codebase, and the REST API enables integration with payment gateways, shipping providers, and third-party services. Deployable via Docker Compose or the bench CLI tool with MariaDB and Redis.

MyCompany runs the whole back office of a small business, sales, stock, production, invoices, projects, payroll, and the shop till, as one application sharing one database. A lead arrives and moves across a kanban board with calls and emails logged on its card, then becomes a sales order and an invoice without retyping a single field. Purchasing raises supplier orders, receives goods into the right warehouse, and watches stock move between locations with full movement history, reservations, lots, and serial numbers. Manufacturing plans production orders from bills of materials with operations and work centers, tracking the materials actually consumed and what each finished batch cost. Projects track tasks and time with supervisor timesheets, HR keeps employee records, hourly rates, and payslips, and the retail point of sale handles barcodes, payments, register sessions, and discounts. Because every module reads and writes the same records, the invoice knows what the warehouse shipped and the project knows what the customer was billed. When your business outgrows a standard screen, customizations live in separate extension modules, so vendor updates never collide with the workflows you adapted. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Bigcapital gives small and medium businesses a complete double-entry accounting, invoicing, and inventory management platform they can self-host for free, replacing the per-seat subscriptions of QuickBooks, Xero, and Wave. Every transaction records debits and credits across your chart of accounts, automatically generating balance sheets, profit and loss statements, trial balances, general ledger reports, journal entries, accounts receivable and payable summaries, cash flow analysis, inventory valuation, and inventory summary reports. Sales invoicing supports recurring schedules, customer payment tracking, estimate-to-invoice conversion, and configurable GST/VAT tax rates. Purchase invoicing handles vendor bills with expense categorization for payroll, rent, and operational costs. The inventory module tracks stock levels using FIFO and average cost methods, automatically adjusting quantities on every sale or purchase and providing reorder alerts. Multi-currency accounting converts transactions at real-time exchange rates and consolidates them under customer or vendor profiles with detailed currency reports. The platform deploys via Docker Compose with multi-tenant isolation giving each organization its own separate database, requiring as little as 2GB RAM for the complete production stack. A headless REST API with Postman collections lets developers embed the accounting engine into external applications for programmatic transaction management. Role-based permissions control access for team members and invited accountants across organizations.

jshERP lets a small or midsize business, from a shop to a wholesaler, run purchasing, stock, sales, and money from one place instead of scattered spreadsheets. A purchase requisition becomes a purchase order, then a receipt that raises stock. A sales order becomes an outbound delivery that lowers it, or a purchase order when more must be bought in. Retail sales, returns, and serial-number scanning run through the same stock. Products sit in a category tree up to three levels deep, with barcodes, images, multiple attributes, customer-specific prices, and a base unit plus up to three secondary units. Transfers move goods between warehouses, assembly and disassembly merge and split products, and shelf locations record where each item sits. Other receipts and issues cover opening stock, stocktake corrections, and scrapped goods, while moving-average cost keeps valuation current. Finance logs income, expenses, receipts, payments, transfers, and prepayments against settlement accounts, and customer and supplier reconciliation reports export to Excel. Reports track stock levels, low-stock alerts, in-out statistics, and purchase and sales summaries, and the home page totals yesterday's and retail sales. Roles limit access down to single menus and buttons and can mask prices. A tenant model runs several businesses on one installation, and the interface switches among 73 languages.

With over 11,500 GitHub stars, 20 contributors, and nine releases through version 1.4.0 in May 2026, Aureus ERP has established itself as the modern Laravel-powered alternative to legacy ERP systems like Odoo and ERPNext by packaging accounting, inventory, manufacturing, HR, sales, procurement, and project management into a modular MIT-licensed platform where you install only the plugins your business actually needs. Built on Laravel 13 with FilamentPHP 5 admin panels and TailwindCSS, each module installs via a single Artisan command that automatically resolves dependencies, runs migrations, seeds default data, and generates role-based permissions through Filament Shield integration. The Accounts module defines chart of accounts, journals, ledgers, currencies, and fiscal structures while the Accounting module handles journal entries, financial reports, period closing, and reconciliation workflows. Inventory management provides warehouse operations with stock tracking, transfers, and adjustments while Manufacturing handles bills of materials, manufacturing orders, work orders, and work center scheduling. The Sales module manages pipeline stages and opportunity tracking while Purchases handles procurement workflows and vendor management. HR capabilities span employee management, recruitment with applicant tracking, leave management through Timeoffs, and employee hour tracking via Timesheets. The Projects module provides planning and task management with the Maintenance module covering preventive and corrective equipment maintenance with calendar views. Docker deployment pulls a single image bundling PHP, MySQL, Apache, and Node.js for immediate browser access.

Metasfresh is a free, open-source ERP system that runs the whole commercial life of an industry or trade company, from the first lead and quotation through sales orders, warehouse shipments, manufacturing orders, and the invoices that close the books. The CRM module keeps business partner master data for customers and vendors, tracks prospects, leads, tasks, and opportunities, and shows the sales pipeline. Sales staff create quotations, convert them into sales orders with credit limit checks and Incoterms, and follow each order through shipment planning to the customer invoice. Purchasing mirrors the flow on the vendor side: procurement planning and purchase dispositions generate purchase orders, goods receipts book deliveries into stock, and vendor invoices match what actually arrived. Manufacturers work with bills of materials, MRP II planning, and manufacturing orders that consume components and finish products, and production planning ties resources to schedules. The warehouse module manages storage locations and handling units, books inventory movements between warehouses, and counts physical stock, so promised quantities match what the floor can actually ship. Accounting posts invoices, credit notes, and reversals for debtors and creditors with automatic FACT accounting entries, keeping the ledger current. Every screen is a responsive web interface that adapts from office monitors to tablets on the warehouse floor, and a REST API connects shop systems and third-party tools to the same data. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPLv2 and GPLv3 dual licensed.

Your next business system does not need a year of scaffolding: Open Mercato hands you a running CRM, ERP, and commerce back office, and your team builds only the logic that makes your company different. Deals and pipelines live next to the product catalog, so a quote pulls real variants, price lists, and stock without swivel-chair exports. Orders flow into invoices, shipments, and payments in one motion, while warehouse lots and stock movements keep fulfillment honest about what can actually ship today. Customers and partners stop emailing your team for status: the self-service portal takes B2B orders, shows tracking, and files warranty claims directly. When a record needs a field nobody planned for, an administrator adds the custom entity from the panel, no migration deploy, and shapes its lifecycle with per-tenant workflows and business rules. Every change lands as an auditable command with an author attached, so mistakes get undone, sensitive columns get encrypted per tenant, and several companies share one install without seeing each other's data. Storefronts and mobile apps plug into generated REST APIs with OpenAPI documentation, attachments turn searchable through OCR, and AI coding agents extend the system because the architecture conventions are written down for them.

In Tryton, an invoice knows its shipment and a production order knows its stock, since accounting, inventory, purchasing, and sales are modules of one ERP rather than separate programs exchanging exports. Financial accounting posts customer and supplier invoices, reconciles bank statements imported from SEPA or configured CSV formats, manages dunning and direct debits, and produces Factur-X electronic invoices, while analytic accounting splits results across cost centers. Stock tracks goods through warehouses and locations with lots, shipments, inventories that warn when counts drift beyond tolerance, and automatic period closing, and production consumes bill-of-material inputs into finished goods with quantity checks. Sales quotations become orders, shipments, and invoices without retyping; purchases calculate real supplier lead times; point of sale records lot numbers at the till; subscriptions bill recurring services on schedule. Multi-company installations share the same database with per-company wizards, tax rules can be defined per organization for European trade, and parties, products, carriers, currencies, and customs duties are managed as shared reference data. Access happens through the browser web client, a desktop client, or scripting and REST libraries, so integrations read and write the same business objects your staff see.

Sell from one storefront or eleven at once: Maho runs your whole shop, from the product grid shoppers browse to the admin grids where you run the business. Customers filter arrivals by price, color, size, fit, and material, open a product page with gallery, stock status, and reviews, and check out in one step with social login and saved cards. In the admin you build customer segments from lifetime value and last-order rules, shape Google Shopping feeds element by element in the XML builder, review revocation requests in a searchable grid, and set up gift cards with fixed amounts and lifetimes from the product tab. Eleven storefront themes come with a live theme editor, a drag-and-drop page builder, an image editor, and content versions, while marketing tools cover email automation, dynamic categories, and a blog. Multi-store setups run many websites, stores, and currencies from one installation, and payments span PayPal, Braintree, Mollie, Klarna, and more first-party modules.

Shopware is where a merchant's products, prices, stock, orders, and customers live when the catalog must sell through a storefront, a headless front end, and marketplace feeds at once. Merchants manage products, variants, prices, stock, orders, and customers in a single administration, then publish them to any number of sales channels, from the classic storefront to comparison portals and social shopping feeds. Shopping Experiences gives the marketing team a drag-and-drop editor for landing pages, category layouts, and shop pages, so campaigns launch without a developer touching templates. The Rule Builder turns conditions about carts, customers, and products into living business logic that controls shipping costs, payment availability, advanced prices, and who qualifies for which promotion. Flow Builder acts on shop events automatically, sending order documents, changing order statuses, or calling external URLs when those rules match, removing hours of manual back-office work. Promotions support percentage and fixed discounts, voucher codes, usage limits, and validity windows, while cross-selling, reviews, tags, and configurable search help shoppers find and trust the catalog. Customer groups with net or gross pricing, multi-currency and tax handling, and unlimited languages let the same installation sell into several countries at once. The Store API can drive a custom headless storefront or a point-of-sale client while the standard storefront keeps running untouched, and 3,100+ community extensions add payment providers, shipping integrations, and marketing tools.

Why rent your own shop from a platform that takes a cut and sets the rules? Openfront runs the whole store, storefront and back office together, on a server you own. Customers get a fast, mobile-responsive store where they can browse the catalog, open product pages with variants, fill a cart, check out, create an account, and follow their orders. You get the dashboard behind it: products and variants, orders and fulfillment, customers, payments through Stripe and PayPal, shipping integrations, and the everyday work of running a store without ten browser tabs. Stock is tracked across multiple locations with movements and backorders, so a warehouse and a shop floor stop disagreeing about what exists. Gift cards run their full life from creation to redemption, returns and refunds follow a proper claims workflow instead of an email thread, and discounts can be simple codes or automated campaigns. Selling abroad is built in, with multiple currencies and regional pricing, while analytics and reporting show what is actually selling. When clicking through menus is slower than saying it, the built-in AI assistant can add products, change prices, and configure regions from a chat, working inside your own logged-in permissions so it can only do what your role allows.

InvenTree is an inventory management system for electronics manufacturers, makerspaces, and small-to-medium businesses. The hierarchical part categorization system organizes components into unlimited nested categories, while stock items tracked across cascading locations and sub-locations provide instant visibility into current inventory levels, with optional serial number tracking for individual item traceability and acceptance testing. Intelligent BOM management calculates sub-part requirements, validates availability against current stock, supports multi-format BOM upload including KiCad integration, and generates detailed bills of materials with full database enrichment. Build orders consume BOM-allocated stock to produce assembled parts with step-by-step work order tracking, while purchase orders manage supplier relationships with pricing history, lead times, and automatic stock receipt processing. The modern React frontend built with Mantine, TanStack Query, and Zustand provides responsive data tables, tree-select navigation, a preview drawer, and a snippet editor. The extensible plugin system supports 19 mixin types including BarcodeMixin for scanner integration, LabelPrintingMixin for Zebra and Brother printers, AppMixin for custom database tables, and ScheduleMixin for periodic background tasks.
