10 ERP System Examples by Business Size (2027)

What an ERP system does

ERP stands for enterprise resource planning. An ERP system is a single platform that runs your core processes on one shared database: accounting, inventory, purchasing, sales, manufacturing and reporting. When a sales order is entered, stock, finance and purchasing all see it at once.

The alternative is a patchwork of spreadsheets and separate apps that need manual re-entry. A patchwork works at ten orders a day and breaks at a few hundred. ERP system examples vary by size, industry and how much you can customize, so this guide groups ten real systems by the size of business they suit.

ERP examples for small businesses

1. Odoo: modular apps with a free entry point

Odoo is a modular business suite. Its pricing page lists a One App Free plan covering one app with unlimited users, a Standard plan with all apps, and a Custom plan, both billed per user per month. Custom adds multi-company support, Odoo Studio, the external API and hosting options such as Odoo.sh or on-premise, and it also lists agentic AI. A separate Community edition is open source. Our guides on the benefits of Odoo and on AI agents for Odoo go deeper.

Choose it if you want to add modules as you grow. Watch for hosting and customization costs, which sit outside the user price.

2. ERPNext: open source with no per-user hosting fee

ERPNext, from Frappe, describes itself as 100% open-source ERP. Its modules include accounting, procurement, sales, CRM, stock, manufacturing, projects, assets, point of sale, quality and support, with HR and payroll in a separate Frappe HR product. On Frappe Cloud there is no per-user pricing, and you pay only for hosting.

Choose it if you have technical help and want control of the code. Watch for the work of customizing and supporting it yourself.

3. SAP Business One: SAP for smaller companies

SAP positions Business One for small and midsize businesses. It covers accounting and financials, purchasing, inventory, sales and customer relationships, and reporting. It is sold through partners and can run in the cloud or on premise, so implementation usually goes through a reseller.

Choose it if you want a recognized brand with a path to larger SAP products. Watch for partner quality, which shapes the whole project.

ERP examples for growing and mid-sized businesses

4. Microsoft Dynamics 365 Business Central: ERP for Microsoft shops

Microsoft describes Business Central as AI-powered ERP for small and midsize businesses, combining finance, sales, service and operations. Pricing is per user, billed yearly: Essentials at $80 a month, Premium at $110 a month, which adds service management and manufacturing, and Team Members at $8 a month for limited access. A free 30-day trial is offered, and Microsoft cites more than 55,000 customers. It includes Expense, Sales Order and Payables agents, and works with Outlook, Excel, Teams and Power BI.

Choose it if your team lives in Microsoft 365. Watch for add-ons and partner services on top of the license.

5. Oracle NetSuite: cloud ERP for scaling companies

NetSuite is Oracle’s cloud ERP suite, covering financials, inventory, order management and more in one platform, with options for e-commerce and CRM. NetSuite is usually bought through a partner and priced by quote, and customer counts differ by source, so we do not quote one. Our NetSuite consulting guide explains what to ask a partner.

Choose it if you are growing across entities, currencies or channels. Watch for license, module and customization costs that add up quickly.

6. Acumatica: resource-based pricing with unlimited users

Acumatica says customers can give unlimited users access and pay for the functionality and resources they use, not for user seats. It does not publish a price list, and it is sold through resellers, so quotes come from them.

Choose it if many light users need access, such as field staff. Watch for transaction volume, which can raise the bill.

7. Sage Intacct: finance-first cloud ERP

Sage describes Intacct as a cloud-native financial management and accounting platform for growing organizations. Its strengths include multi-entity consolidation, multi-currency, real-time dashboards, automated workflows and open APIs.

Choose it if finance is your core problem. Watch for operations depth: it is strongest on accounting and may need partner apps for inventory or manufacturing.

ERP examples for large and industry-specific operations

8. SAP S/4HANA: the large-enterprise standard

SAP S/4HANA comes in public cloud, private cloud and on-premise forms. Public Edition is multi-tenant software as a service, aimed at new customers who accept a standardized model with regular upgrades. Private Edition is single-tenant and allows more customization. On-premise gives the most control and the most operating cost. SAP bundles these through GROW with SAP and RISE with SAP.

Choose it if you run complex, multi-country operations. Watch for long, partner-led projects.

9. Epicor Kinetic: ERP built for manufacturers

Reviewers describe Epicor Kinetic as a cloud ERP designed for manufacturers, covering discrete, mixed-mode and make-to-order environments. Its AI layer is called Epicor Prism.

Choose it if you build products to order. Watch for fit if you are a multinational with many product lines.

10. Infor CloudSuite: pre-built industry editions

Infor CloudSuite is a cloud ERP suite for medium and large manufacturers, distributors and service providers, with industry editions such as Industrial, Distribution and Healthcare. Reviewers note its broad feature set can require training and experienced certified partners.

Choose it if an Infor edition matches your industry closely. Watch for opaque pricing that varies by edition.

The 10 ERP examples side by side

ERP modules you will meet

ERP software is sold as modules. Most businesses buy a few first and add the rest later.

• Finance and accounting: ledger, payables, receivables, bank reconciliation, reporting.
• Inventory and warehouse: stock levels, locations, barcode scanning, reorder points.
• Purchasing: purchase orders, supplier records, approvals.
• Sales and CRM: quotes, orders, customers and pipeline.
• Manufacturing: bills of materials, production orders, planning.
• Projects: time, costs and billing for service work.
• HR and payroll: sometimes a separate product, as with Frappe HR.

ERP for small business: how to choose ERP software

The best ERP for small business is the one that covers your main process and that your team will actually use. Work through these steps in order.

1. Write down your three biggest pains. Slow month-end close, stock errors and manual order entry are typical.
2. Map the modules you need now. Buy those first, and check the vendor can add the rest.
3. Compare pricing on your headcount. A per-user plan costs less with ten users than with a hundred. Acumatica-style resource pricing flips that.
4. Check your existing stack. If you sell online or run a CRM, test the connection early. Our guides on e-commerce ERP integration and CRM and ERP integration show what to test.
5. Pick the partner, not just the product. Ask for references in your industry and what your team inherits after launch.
6. Run a paid pilot. Load a month of real data into a trial before you sign.

AI is changing ERP too. Business Central already ships agents for expenses, sales orders and payables, which we cover in our guide to AI agents in ERP.

Mistakes that sink ERP projects

• Buying on the demo. Test the screens your own staff will use every day.
• Customizing everything. Every custom change costs money at each upgrade. Change your process before you change the software.
• Skipping data cleanup. Duplicate customers and messy item lists move into the new system unless you clean them first.
• Under-training staff. Plan hands-on training before go-live, not after.
• Forgetting integrations. Payments, shipping, e-commerce and CRM links are separate projects and need their own budget.

Frequently Asked Questions

What are examples of ERP systems?

Examples include Odoo, ERPNext, SAP Business One, Microsoft Dynamics 365 Business Central, Oracle NetSuite, Acumatica, Sage Intacct, SAP S/4HANA, Epicor Kinetic and Infor CloudSuite. They cover companies from a handful of staff to global enterprises.

What is the best ERP for a small business?

There is no single best. Odoo and ERPNext suit companies that want low entry cost and flexibility, Business Central suits Microsoft 365 teams, and SAP Business One suits those who want an SAP product. Match the system to your process and your partner.

What is an ERP system in simple terms?

It is one platform that runs your finance, inventory, purchasing and sales on a shared database. Instead of re-entering an order in three apps, you enter it once and every team sees it.

How much does ERP software cost?

It varies widely. Business Central lists $80 to $110 per user per month, Odoo has a free plan for one app, ERPNext charges only for hosting, and many vendors quote by partner. Implementation and customization often cost as much as the licenses.

What are the main ERP modules?

Finance, inventory, purchasing, sales and CRM, manufacturing, projects, and HR and payroll. Start with the modules that fix your biggest pains and add others later.

What is the difference between ERP and CRM?

CRM manages customer relationships, such as leads, deals and follow-up. ERP runs the operations behind them, such as orders, stock and accounting. Many ERP suites include CRM, and the two usually integrate.

Is open source ERP a good choice?

It can be. ERPNext is open source, and Odoo has an open source Community edition. You gain control and lower license cost, and you take on more customization, hosting and support work.

How long does an ERP implementation take?

It depends on scope, data quality and customization. A narrow rollout of finance and inventory is far quicker than a multi-entity manufacturing project. Ask your partner for a phased plan with dates tied to deliverables.

Can an ERP connect to my online store?

Yes. Business Central lists a Shopify connector, and most ERPs offer integrations or APIs for e-commerce. Test order, inventory and customer sync with real data before launch.

Bottom Line

ERP system examples are easiest to compare by size. Odoo, ERPNext and SAP Business One suit small companies, Business Central, NetSuite, Acumatica and Sage Intacct suit growing ones, and SAP S/4HANA, Epicor Kinetic and Infor CloudSuite suit large or industry-specific operations.

Choose by your biggest process pain, your headcount and your partner, and run a pilot with real data. When you want help picking or implementing, our Odoo development services team can scope it with you.
