Best Affordable ERP Software (2026): Top 10 Compared

Odoo is a modular suite of business applications covering sales, eCommerce, accounting, CRM, inventory, HR, projects and point of sale on one database. Its pricing page lists three plans. One App Free charges nothing for a single application with unlimited users on Odoo Online, and the page states that any apps the chosen app depends on are also free, with no limit on users or time. Multiple companies are allowed on the free plan, and Odoo Studio can be chosen as the free app.

Standard and Custom are charged per user per month, with a yearly or monthly toggle. Standard includes all apps on Odoo Online. Custom adds Odoo Studio, multi-company, the external API and the choice of Odoo.sh or on-premise hosting; Odoo.sh hosting is billed separately. The page renders prices in the visitor's local currency. Viewed from India on the check date, Standard showed Rs 725 per user per month on yearly billing, with a first-year discount for initial users. A Light User type is also listed. Implementation services and custom code maintenance are excluded.

Odoo suits small businesses that want one app free today and a path to a full suite without changing products.

ERPNext is an open-source ERP built by Frappe on its own web framework. Its module list covers accounting, procurement, manufacturing, point of sale, projects, assets, quality, support, sales, CRM and stock. The pricing page states that ERPNext is free and open source under GPL-3.0, that its source code has been open since 2009, and that Frappe does not hold back enterprise features for payment.

The page splits the cost into hosting and implementation. Self-hosting on the buyer's own server uses Frappe's installation scripts and suits companies with a technical team. Frappe Cloud, the vendor's managed host, sells site plans on shared servers from $5 per month and virtual machine servers from $20 per month, with higher-reliability dedicated servers from $125 per month. The page states that hosting is charged for usage, not per user. Implementation can be done by the buyer using the documentation, through a partner Starter Pack, or through one of more than 200 certified partners; Frappe itself does not provide implementation services.

ERPNext suits businesses that want broad ERP coverage without a licence fee and can either run the system themselves or budget for partner help.

Dolibarr is an open-source ERP and CRM suite for small and mid-sized companies, freelancers and associations. The project site describes a free open-source software model in which buyers enable only the modules they need, with integration between modules built in and upgrades possible from any earlier version without data loss. An open marketplace offers external add-ons for needs the core does not cover.

The core modules span prospects and clients, opportunities, proposals, orders, contracts and subscriptions, help desk tickets, HR functions such as expense reports, leave and timesheets, products and stock, purchasing, shipments, manufacturing, invoicing and payments, bank reconciliation, double-entry accounting, email marketing, projects and an API.

DoliCloud, the official preferred hosting partner, runs Dolibarr as a hosted service in Europe. Its site lists Dolibarr Basic at €14 per month per user and Dolibarr Premium from €45 per month. Each starts with a 30-day free trial with no credit card and full access to the database, program files and setup. The site states that a customer can switch to self-hosting at any time.

Dolibarr suits small organisations that want a modular system at no licence cost, with a hosted option for teams without a server.

Axelor is a French open-source ERP platform that pairs business modules with a low-code layer. Its pricing page describes the range as running from free open source to an Enterprise offer with built-in AI, and states that the company is ISO 27001 certified and runs a certified e-invoicing platform.

Three plans are listed. Community costs €0 and is a download, described for exploring the platform and for independent projects; it includes the open-source platform, essential modules and community support. Pro is €35 per user per month on annual billing or €40 on monthly billing, starting at 10 users. It adds a commercial licence, all business modules, updates, e-invoicing, standard support and access to Axelor AI. Enterprise is €55 annually or €60 monthly per user, starting at 20 users, and adds built-in AI agents that act inside modules, advanced BI, CAS and SSO, priority support, indexed search, an advanced import and export module, an advanced Studio for screen customisation and document templates.

Axelor suits small and mid-sized businesses, particularly in Europe, that want to trial an ERP free and then move to a supported licence. Teams under ten users should check whether Community covers their needs.

Striven is an all-in-one business management system from Miles IT aimed at small and midsize businesses. Its feature menu covers accounting, CRM and sales management, project and task management, inventory, OKRs, human resources, portals and workflows. Industry pages include construction and contracting, logistics, retail and eCommerce, discrete and process manufacturing, field services such as HVAC and plumbing, and professional services.

The pricing page lists two monthly plans. Standard is $35 per user and Enterprise is $70 per user, and both offer a free trial. Accounts with fewer than five users add $25 per user to the rate. Portal plans are priced per portal per month: customer, vendor and career portals are free up to 100 customers, vendors or applications a month, $99 for up to 500, and $499 for unlimited. The page states that each plan upgrade allows more users, customers, vendors and candidates, and the vendor lists free implementation guides and training material.

Striven suits small service firms that would otherwise pay separately for accounting, CRM and project tools and want a single published per-user price. Very small teams should include the under-five-user surcharge in their estimate.

Katana is cloud inventory and manufacturing software for product businesses. Its feature set covers inventory management, manufacturing, purchasing, order management and warehousing, with batch, serial and expiry tracking, real-time production costing, multi-channel order syncing and AI replenishment recommendations. Listed integrations include Shopify, Amazon, QuickBooks Online and HubSpot, plus an open API and Model Context Protocol support for AI tools. Accounting is handled by the connected accounting product.

The pricing page lists two plans. Free costs $0 with no card required and is described for exploring Katana on a small product catalogue. It includes up to 30 SKUs, unlimited users, integrations and inventory locations, all Katana features, API access, and an AI assistant and knowledge base for support. Advantage has custom pricing and covers unlimited SKUs, a setup scoped to the business, custom integrations, reports and automations, multi-step workflows, a named Customer Success Manager, 24/7 live support and regular inventory consultations, all under one annual contract. The page notes that customers on older Standard, Professional, Professional Plus or Core plans will be contacted about changes.

Katana suits small manufacturers that can work within 30 SKUs while evaluating, or that plan to budget for a scoped Advantage contract.

Flectra is an open-source ERP and CRM system from FlectraHQ with a modular design. Its feature menu covers CRM, sales, point of sale, subscriptions, rental, accounting, invoicing, expenses, documents, spreadsheets, email marketing, surveys, purchasing, inventory, human resources, manufacturing, projects and helpdesk.

Two editions are offered. Flectra Community is a free download, with packages for Debian, Red Hat and Windows, source files, and instructions for Docker or Kubernetes. The vendor describes Flectra Professional as the Community edition plus professional add-ons and a support contract. Its comparison page lists functional support, version upgrades, hosting, the No Code Studio, DocuSign, automated marketing and to-do among the items available only in Professional. The pricing page calculates Professional prices in an interactive quote builder that varies by number of users, country, hosting option (cloud billed annually or on-premise one-time) and billing period, so no figure was recorded. A free cloud trial is offered without a credit card.

Flectra suits small businesses with someone able to install and maintain the Community edition. Buyers who need upgrades and support should request a Professional quote before comparing it with other paid plans.

Tryton is open-source business software governed by the Tryton Foundation and described on its homepage as 100 percent open source and ideal for companies of any size. It uses a three-tier architecture: an application server connected to a PostgreSQL database, web or desktop clients, and server modules for business logic.

The integrated feature list covers financial and analytic accounting, sales from quotation onward, inventory and stock, CRM, purchasing with grouped requests for quotation, supply chain replenishment, manufacturing with bills of materials and routings, shipping, project management with profitability tracking, subscription management with recurring invoices, and third-party integration with banks, carriers and websites.

The download page offers a weekly-updated Docker image that the project describes as production ready, desktop clients for Windows, macOS and Linux, and signed source archives. Releases ship every six months and are supported for one year, and each new major release carries five years of long-term support. Version 8.2 was released on 6 October 2026. No licence fee is listed, and the site directs buyers who want help to a network of independent service providers.

Tryton suits companies with developers or a chosen service provider that want a modular platform with no vendor lock-in.

iDempiere is a community-developed open-source ERP, CRM and supply chain system founded in 2011, which the project describes as Tier II. Its homepage headline is Free Open Source ERP and CRM, and it presents the software as serious, used worldwide, and with no licensing cost.

The project lists its reasons for adoption: it is easy to install, runs on a small server and scales to hundreds of users. It uses widely available technologies, namely Java, ZK, OSGi, Maven and an Oracle or PostgreSQL database. It also states that iDempiere has an enterprise-quality accounting system, supports multiple entities or sets of books inside a single login, and has a supporting ecosystem for business intelligence, workflow and portals. The project's current long-term support release is iDempiere 13, codenamed Orion. The community runs testing days, publishes feature updates such as saved queries in the Find window, and takes part in Hacktoberfest.

iDempiere has no commercial vendor behind the project, so hosting, implementation and support come from the community or independent implementers. It suits businesses with several entities and access to Java skills that want a full accounting core without licence fees.

Apache OFBiz is a suite of business applications and a Java web framework maintained by the Apache Software Foundation, where it has been a top-level project since 2006. The homepage states that OFBiz is free and open source with no upfront costs and no licensing fees, and the project is released under the Apache License 2.0.

The core modules include accounting with general ledger, receivables, payables and fixed assets, CRM, order management and eCommerce, warehousing and inventory, and manufacturing and MRP. Listed features include product and catalogue management, promotion and pricing management, supply chain fulfilment, and contracts, payments and billing. The framework itself provides an entity engine, a service engine and a widget-based user interface, which the project says lets developers prototype and extend applications quickly.

Getting started requires installing the Java Development Kit and following the instructions in the README, and the project offers online demos and separate starting pages for developers and business users. Support comes through mailing lists, an issue tracker and a chat channel rather than a commercial plan.

OFBiz suits organisations with Java developers that want a mature ERP base to customise heavily, rather than a ready-configured product.
