Best ERP for small business: seven systems compared by fit and pricing model

ERP (enterprise resource planning) software puts your core operations in one system with one database: accounting, purchasing, inventory, orders and often manufacturing, projects or HR. The pitch is simple. Instead of five tools that disagree about how much stock you have, you get one record everyone works from.

The hard part for a small business isn’t understanding the idea. It’s that ERP vendors price in very different ways, and most of the total cost sits in implementation, not the license. This list sets out seven systems side by side, with the pricing model first and the vendor’s own published numbers where they exist.

At a glance#

System	Pricing model	Published price	How you usually buy	Strongest fit
Oracle NetSuite	Annual license: platform + modules + users, plus implementation fee	Quote only	Direct or partner	Fast-growing companies expecting to add entities and modules
Acumatica	Based on applications and resources used, not per user	Quote only (industry calculators)	Partner	Distribution, construction, manufacturing with many occasional users
Odoo	Per user per month; one app free	From US$16.90 per user per month (Standard)	Online, self-serve	Budget-conscious teams that can configure software themselves
Microsoft Dynamics 365 Business Central	Per user per month, paid yearly	$80 Essentials,$ 110 Premium, $8 Team Members	Partner	Companies already on Microsoft 365
SAP Business One	Quote-based	Quote only	Partner	Small firms wanting SAP, cloud or on-premise
Sage Intacct	Custom subscription by industry and size	Quote only	Direct or partner	Finance-led organizations, multi-entity accounting
Katana	Free tier, then custom annual contract	Free up to 30 SKUs; Advantage quote only	Direct	Small manufacturers and product brands

How we compared them#

Industry fit: which industries and business types each vendor’s own pages target.
Pricing model: what you pay for (users, modules, resources) and whether a price is published.
Implementation route: whether you buy and set up directly, self-serve, or through a partner.

The systems#

Oracle NetSuite#

Pricing model	Best suited to
Annual license plus one-time implementation fee	Growing companies that want one cloud suite for finance, inventory and CRM

NetSuite’s ERP product page explains its pricing structure without numbers: you subscribe for an annual license fee made up of three parts (the core platform, optional modules and the number of users), plus a one-time implementation fee for initial setup. More modules can be switched on later. The suite covers financials, order management, inventory, warehouse management and procurement, and NetSuite also sells CRM (customer relationship management) and PSA (professional services automation) on the same platform.

Trade-off: every number comes from a sales conversation, so budgeting means getting a formal quote early.

Acumatica#

Pricing model	Best suited to
Priced on applications and resources, with unlimited users	Distribution, construction and manufacturing firms with many part-time users

Acumatica’s pricing page says it doesn’t charge for user seats. Cost depends on which applications you implement, your transaction volume, resource levels and data storage, and how you deploy. There are no published prices, but the page offers industry calculators for construction, manufacturing and distribution, and buying runs through Acumatica partners. If your warehouse staff, field crews or approvers all need occasional access, not paying per seat can change the math noticeably.

Trade-off: resource-based pricing is harder to compare with per-user quotes, and costs can rise with transaction volume.

Odoo#

Pricing model	Best suited to
Per user per month, with a free single-app plan	Small teams comfortable configuring software themselves

Odoo’s pricing page is one of the few in ERP with prices you can read without a call. One App Free gives you a single app for unlimited users. Standard covers all apps on Odoo’s own cloud (Odoo Online), listed at US $16.90 or US$ 21.10 per user per month depending on billing, and Custom adds hosting options (Odoo.sh or on-premise) and customization at US $32.00 or US$ 40.00. An asterisk notes a discount for the first 12 months on initial users. Odoo’s app list runs wide, from accounting and inventory to manufacturing, website and HR.

Trade-off: low license prices can hide implementation effort; complex setups usually need an Odoo partner or in-house expertise.

Microsoft Dynamics 365 Business Central#

Pricing model	Best suited to
Per user per month, paid yearly	Small and mid-sized companies already using Microsoft tools

Microsoft’s Business Central pricing page lists Essentials at $80 per user per month and Premium at$ 110, both paid yearly. Premium adds service management and manufacturing. A Team Members license at $8 covers people who mostly read data, approve workflows and make limited updates. There’s a 30-day free trial, and the page directs buyers to a partner for purchase and setup. It also notes that prices vary by country and region, and that agent usage through Copilot Studio is billed separately.

Trade-off: the license price is clear, but partner implementation is where most of the first-year cost sits.

SAP Business One#

Pricing model	Best suited to
Quote-based, through partners	Small companies that want an SAP product with cloud or on-premise options

SAP’s Business One page positions it as ERP for small businesses, covering accounting and financials, purchasing, inventory, sales, customer relationships and reporting. SAP says over 85,000 customers use it. Deployment can be cloud or on-premise. Pricing is by quote; the page’s calls to action are “Request a quote” and “Contact us.”

Trade-off: you’ll depend heavily on the partner you choose, so vet the partner as carefully as the software.

Sage Intacct#

Pricing model	Best suited to
Custom subscription by industry and organization size	Finance teams that need strong multi-entity accounting

Sage Intacct is a cloud financial management system with ERP modules around it. Its pricing page says plans are tailored to your industry and size, with a “get a free quote” route rather than published prices. It’s strongest when the finance function drives the purchase, for example a company with several legal entities or locations that needs consolidated reporting.

Trade-off: it’s finance-first, so inventory-heavy or manufacturing businesses may need extra modules or connected systems.

Katana#

Pricing model	Best suited to
Free plan, then a custom annual contract	Small manufacturers and product brands selling across channels

Katana focuses on manufacturing and inventory rather than full accounting. Its pricing page offers a free plan for up to 30 SKUs (stock keeping units) with unlimited users, integrations and locations, all features and API access. Beyond that, Katana sells Advantage, a custom annual contract scoped to your setup, with implementation and customer success support included and no per-user charges. Katana connects to separate accounting software rather than replacing it.

Trade-off: it isn’t a full ERP on its own; you’ll still run accounting elsewhere and rely on integrations.

How to narrow the list#

Start with your industry. Manufacturers should look hardest at Katana, Business Central Premium, Acumatica and NetSuite; distributors at Acumatica, NetSuite and Business Central; finance-led service firms at Sage Intacct and NetSuite. Then decide how you want to buy. If you want to start without a sales call, Odoo and Katana’s free plan let you. If you want a local expert from day one, Business Central, Acumatica and SAP Business One all run through partners.

Finally, list the systems your ERP must talk to: your online store, payment provider, shipping tools and CRM. Ask each vendor which of those connections are built in and which need extra work. Our guide to API integration explains what to ask, and if the list is long, an integration platform may sit alongside the ERP. For real-time events like new orders, check whether the ERP supports webhooks; API vs webhook explains why that matters.
