Best NetSuite Alternatives in 2026: ERP Software, Including Free and Open-Source Options

The best NetSuite alternatives depend on your size, your industry and how much implementation work you can take on. Odoo and ERPNext are the strongest open-source ERPs, with ways to run them without a per-seat licence. Dynamics 365 Business Central and SAP Business One are established suites for small and mid-sized companies, and Acumatica ties licensing to resource use instead of named users.

The same shortlist answers the broader searches for the best ERP software and free ERP software. This guide covers ten options, hosted and self-hosted, and says what each one is built for, how it differs from NetSuite and what to check before you commit. No ERP is best for everyone: the right one depends on the modules you need.

Why people look for NetSuite alternatives

NetSuite is Oracle's cloud ERP suite, covering financials, inventory, order management and commerce for growing and mid-sized companies, with multi-subsidiary and multi-currency support. Teams compare it with alternatives for reasons like these:

• Pricing is not published. NetSuite uses a contact-sales model, so a quote has to be requested and compared against your own module list rather than read from a page.
• Closed source and cloud only. The code is proprietary and there is no self-hosted version, so you cannot run it on your own servers or inspect it.
• More system than the job needs. A company that mainly needs accounting and inventory may be better served by a lighter product, and the cheaper end of the ERP market includes free open-source options.
• Vendor and ecosystem fit. Companies standardized on Microsoft, SAP or Sage products may prefer the ERP from that vendor because it fits the stack they already run.
• Industry depth. Manufacturers, distributors and healthcare organizations sometimes want ERP with industry processes built in, which Epicor and Infor target.
• Licensing model. Per-user pricing, consumption-based licensing and no-per-user hosting all exist in this category, and the model changes how cost scales as you hire.

How we picked

Enlisted looks for ERP systems that cover core finance together with operational modules such as inventory, purchasing, sales or manufacturing. For open-source projects it checks the licence, whether you can self-host, and whether the GitHub repository is still being worked on. For commercial products it reads the vendor's published pricing model and deployment options. Where a vendor does not publish details, as with several ERP suites that quote through sales, this guide says so instead of guessing. Method details are in how Enlisted ranks tools.

What to settle before you compare ERP systems

ERP is a bundle of modules, and the shortlist changes as soon as you decide which ones you need. Write down the answers to these first:

• Modules. Accounting, inventory, purchasing, order management, manufacturing, projects, CRM, HR, point of sale or commerce. Depth in manufacturing, warehouse management and project accounting varies a lot between products.
• Structure. One company or several subsidiaries, one currency or many.
• Deployment. Hosted by the vendor, hosted by a partner, or installed on your own servers. Some products on this list offer more than one.
• Licensing. Per user, by resource consumption, by hosting plan, or free software with paid support.
• Implementation effort. Who will configure it, migrate your data and train staff. For ERP, implementation can take more time and money than the licence itself.

If accounting is the real need and ERP is aspirational, read Enlisted's guide to QuickBooks alternatives first. A full ERP may be more than you need.

1. Odoo: best open-source ERP for adding modules as you grow

Odoo is a set of browser-based business apps, covering CRM, eCommerce, a website builder, inventory and manufacturing, projects, invoicing and accounting, point of sale, HR and marketing, that you can use alone or together as an ERP. The difference from NetSuite is the starting point: a company can begin with one app, such as sales or invoicing, and add others without changing platforms.

Its pricing page lists a free plan with one app for unlimited users, plus paid Standard and Custom plans billed per user, with a free trial. On-premise hosting is part of the Custom plan. The code is written in Python, and GitHub lists the licence as "Other", so read the repository for the exact terms.

• Best for: growing companies that want to start small and add apps over time.
• Watch out for: paid plans are per user, so cost rises with headcount, and which apps, hosting option and plan you need determines what you pay. Check the Odoo pricing page.

2. ERPNext: best free open-source ERP for accounting, inventory and manufacturing

ERPNext is a free open-source ERP built on the Frappe framework, covering accounting, inventory, order management, manufacturing, assets and projects in one system, with HR, CRM and procurement modules as well. It aims to replace the patchwork of separate programs a business uses for invoices, stock and operations.

The software is GPL-3.0 licensed and free to self-host. Frappe Cloud is the paid hosting option, priced by site and server rather than per user, and a free trial is available. Frappe Docker provides the official Docker images for running ERPNext yourself.

• Best for: small and mid-sized companies and manufacturers that want one self-hostable system without a per-seat licence.
• Watch out for: free software still needs implementation, hosting and upgrades handled by your team or a partner. See the ERPNext pricing page for hosted options.

3. Dolibarr: best lightweight open-source ERP and CRM for small teams

Dolibarr is an open-source ERP and CRM web application that covers contacts, suppliers, quotes, invoices, orders, stock, accounting, HR, document management and manufacturing. Its listing says it targets small, medium and large companies, foundations and freelancers, and it can run as a standalone application or as a web app over the internet or a local network.

It is a PHP application under the GPL-3.0 licence. Installation options include a Windows installer, packages for Debian, Ubuntu and Red Hat family distributions, a Docker image, or a manual setup on Apache or Nginx with MariaDB, MySQL or PostgreSQL. Commercial support is available through partners.

• Best for: small businesses, associations and freelancers who want a self-hosted ERP and CRM they can install themselves.
• Watch out for: a multi-subsidiary finance team should confirm consolidation and reporting depth before committing, because NetSuite is built for that case and a lightweight package may not match it.

4. Dynamics 365 Business Central: best for Microsoft-centred companies outgrowing accounting software

Dynamics 365 Business Central is Microsoft's ERP for small and mid-sized businesses, covering financial management, supply chain, inventory, sales, purchasing and projects in one application inside the wider Dynamics 365 family. It integrates with Microsoft 365 and the Power Platform, which is the main reason Microsoft-centred organizations shortlist it.

It is available in the cloud and with on-premises deployment options, and Microsoft offers a free trial. It is closed-source commercial software, so editions, modules and pricing come from Microsoft. See the Business Central product page for the current details.

• Best for: small and mid-sized firms already on Microsoft 365 that have outgrown entry-level accounting.
• Watch out for: it is a commercial product with no self-hosted open-source option, so budget time for the implementation, and compare against Business Central alternatives as well.

5. SAP Business One: best for small and mid-sized distributors and manufacturers working through a partner

SAP Business One is an ERP product from SAP for small and mid-sized companies that brings accounting, sales, purchasing, inventory and reporting into one system. It is a lighter option than SAP's enterprise suites. According to its listing, it is sold and implemented mainly through SAP partners, who tailor it to the customer's industry and add extensions, and companies can run it on their own servers or have it hosted in the cloud.

The partner model is both the strength and the cost. A good partner brings industry templates and local support, and the choice of partner shapes how the project goes. Prices are not published on a self-service page.

• Best for: small and mid-sized distributors and manufacturers that want an established vendor and a local implementation partner.
• Watch out for: pricing and implementation are arranged through partners, so get written scope and quotes from more than one. Details are on the SAP Business One page.

6. Acumatica: best for growing companies that want licensing not tied to user count

Acumatica is a cloud ERP for small and mid-sized businesses whose licensing is based on the resources a company consumes rather than the number of named users, so more people can have access without raising the licence cost. It covers financial management, project accounting, multi-entity and intercompany accounting, inventory, order and warehouse management, CRM, payroll and payments.

Industry editions address construction, distribution, manufacturing, professional services and retail, among others. That makes it one to check for project-based or distribution businesses leaving NetSuite. The vendor does not publish prices and offers a custom pricing review instead, as described on its pricing page.

• Best for: growing companies with many users, multiple entities or project-based accounting.
• Watch out for: consumption-based licensing is only predictable once you understand how the resources are measured, so ask for that in writing during the quote.

7. Sage Intacct: best for finance-led teams that need more than entry-level accounting

Sage Intacct is a cloud financial management and accounting system for mid-sized businesses that have outgrown entry-level bookkeeping software. It is listed under both finance and ERP because it covers the core processes other functions rely on. Its listing describes a cloud general ledger, accounts payable and receivable, multi-entity financial management and financial reporting.

Compared with NetSuite, the emphasis is finance rather than a full operations suite. That suits a team whose pain is financial reporting and consolidation, and less so one whose main need is production or warehouse management. Check Sage's site for the current module list and add-ons. See the Sage Intacct alternatives page for what else competes with it.

• Best for: mid-sized companies with a finance-led buying decision and multi-entity reporting needs.
• Watch out for: if operations such as manufacturing or inventory drive the project, check which operational modules are available before shortlisting it.

8. Epicor: best for manufacturers, distributors and retailers

Epicor is a commercial ERP vendor focused on manufacturing, distribution and retail businesses, with software covering accounting, inventory, production, purchasing and order management. It sells several product lines tuned to different sectors and company sizes.

NetSuite is a general-purpose suite, while Epicor starts from specific industries. A manufacturer or distributor that wants inventory, production and order flows handled by an industry-focused vendor should put it on the list, and should confirm product names and deployment options on the vendor's site. Related: Epicor alternatives.

• Best for: manufacturers and distributors that want ERP built around their industry.
• Watch out for: product lines differ by sector and size, so confirm which one fits you, and no pricing is published.

9. Infor: best for industry-specific cloud ERP

Infor sells cloud ERP suites designed for particular industries, including manufacturing, distribution and healthcare, with the industry processes built in instead of added through generic configuration. The vendor also promotes AI agents and automation, with integration platform services and support through partners.

The trade-off against NetSuite is specialization. If your business matches one of Infor's sectors, the built-in processes can shorten configuration. If it does not, a general suite or an open-source ERP may fit better. It is closed source with no published pricing, so a quote is the way to compare. See Infor alternatives for similar suites.

• Best for: manufacturers, distributors and healthcare organizations that want sector-specific ERP.
• Watch out for: industry focus means companies outside its sectors may get less from it, and you will need to request pricing.

10. Oracle Fusion Cloud ERP: best step up for large enterprises

Oracle Fusion Cloud ERP is Oracle's enterprise cloud suite for finance, procurement and project management, aimed at large organizations that need one system for accounting, purchasing and project delivery. Suites of this type generally include general ledger, payables, receivables, asset management, procurement and project financials, so confirm the current modules on Oracle's site.

NetSuite is also an Oracle product, so this is a move within the same vendor and generally toward larger, more complex organizations. It is closed source, delivered from Oracle's cloud, and priced through sales. A team leaving NetSuite over size or cost is unlikely to want it, but it belongs in the comparison for companies growing the other way.

• Best for: large enterprises replacing legacy ERP, and project-driven organizations needing integrated accounting.
• Watch out for: it is built for large organizations, so it may be more than a mid-sized company needs. Compare it with Oracle Fusion Cloud ERP alternatives.

Which NetSuite alternative should you choose?

For small companies, the open-source options and Business Central are the usual starting points. For mid-sized and project-based businesses, add Acumatica and Sage Intacct to the list. The broader ERP category and the NetSuite alternatives page on Enlisted list more.

Is there free ERP software?

Yes, but free covers the software licence, not the project. Here is how it works for the options on this list:

• ERPNext is free to self-host under GPL-3.0. Hosting through Frappe Cloud is a paid option.
• Odoo has a free plan with one app for unlimited users. Paid plans add all apps, and per its pricing page, on-premise hosting is part of the Custom plan.
• Dolibarr is free and open source under GPL-3.0, with commercial support available from partners.
• Metasfresh describes itself as free and open-source ERP for industry and trade companies.
• Ever Gauzy has a free Starter plan for one company and one employee, with paid plans above that.

The real costs sit elsewhere: servers or hosting, data migration, configuration, integrations, training and ongoing support. A free ERP can still be the cheapest option, but only if you have the skills in house or a partner to do that work.

Best ERP software by company size and type

No product is best for every company, but the listings suggest a sensible order. Small companies and teams with technical staff can look at ERPNext, Odoo or Dolibarr. Small and mid-sized businesses that want a commercial vendor and implementation partner can compare Business Central, SAP Business One and Acumatica. Mid-sized finance teams can add Sage Intacct. Manufacturers, distributors and healthcare organizations should include Epicor and Infor, and large enterprises can look at Oracle Fusion Cloud ERP.

More ERP and inventory options

Narrower or smaller options worth knowing:

• Metasfresh: open-source ERP for industry and trade companies, with a Java back end and a React web interface.
• iDempiere: a community-driven open-source business suite covering ERP, CRM, supply chain and manufacturing on Java.
• Ever Gauzy: an open business management platform combining ERP, CRM, HR and project management with time tracking.
• IDURAR: an open-source ERP and CRM on the MERN stack for invoices, quotes and customers.
• Cin7, Katana and Fishbowl: hosted inventory and manufacturing tools for product businesses that need stock control more than a full ERP.
• InvenTree: open-source inventory management for parts and stock.
• Exact Online: cloud accounting and ERP modules, common in the Netherlands and Belgium.

Questions to ask before you sign

Before you pick a vendor or partner, ask each one the following:

• Which modules are included in the quote, and which are add-ons?
• How is licensing counted: users, resources, sites, or hosting?
• Who does the implementation, and what is in scope for data migration and training?
• How are upgrades handled, and what changes between versions?
• Which integrations to your bank, e-commerce platform, payments and payroll are supported out of the box? Enlisted's guides to Shopify alternatives and Stripe alternatives cover two parts of that stack.
• What does exit look like: can you export your data in a usable form?
