Complex permissions and access

Lead Software Engineer

I understand the need for various levels of security, but between tokens and keys and permissions, it's been a big headache.   Once you are connected, you need to know the table relationships before you can begin writing code to exchange data.

Tableau Developer & Data Lead

The security roles are a bit cumbersome to set up and use.

48% of reviewers feel negative about NetSuite’s security and access control. Users report that managing roles, permissions, and account types is confusing and time-consuming. Reviewers indicate that administrators struggle with setting up access for multiple users and integrating with other systems. Some users say frequent password changes and unclear user rights create frustration. They find that access reviews and internal controls are hard to monitor, and the process for granting permissions is tedious, especially for new or non-technical users.

Slow system response times

Accounting Manager

Performance can also be inconsistent at times, particularly with large datasets or saved searches, which can slow down workflows.

Database Administrator

The slow speed of basic actions, such as opening a customer record for viewing or editing makes life difficult.

78% of reviewers feel negative about NetSuite’s performance and speed. Users report frequent slow load times, lag during complex transactions, and delays when running large reports or custom scripts. Reviewers indicate that sluggish performance interrupts workflows and reduces productivity, especially during peak periods or with heavy customization. Some users say updates and customizations can exacerbate speed issues, making basic actions time-consuming. They find inconsistent response times frustrating and note that slow system improvements hinder their ability to adapt quickly.

Limited transaction flexibility

Head of Financial Reporting

A lot of the features are bundled into modules and you have to pay additional subscription in order to use them. When doing the initial sales and scoping call, you may assume some functionality would be standard but only to find out only a very basic functionality is available and then you end up paying more than planned.

53% of reviewers feel negative about NetSuite’s transactions and payments. Users report missing standard features like split payments, refunds for alternative methods, and approval flows for vendor bank changes. Reviewers indicate that many payment and billing functions require costly add-ons or external integrations. Some users say transaction processing is clunky, with too many steps and restrictions. They find that billing modules and integrations often fail to meet expectations, leading to delays and additional expenses for necessary functionality.

Persistent technical problems

NetSuite System Admin

Complex to troubleshoot at times, defects/enhancement requests rarely seem to be addressed in a reasonable time frame.

Senior Accountant

First party add-on modules are NEVER fixed for bugs - things like sorting by name only sort the current page and not the entire population - report to NS and I hear crickets.

67% of reviewers feel negative about NetSuite’s bugs and issues. Users report frequent error messages, workflow failures, and inconsistent functionality that require manual intervention or workarounds. Reviewers indicate that support is often slow or ineffective at resolving technical problems, especially for customizations. Some users say minor bugs and outages disrupt daily operations, and unresolved defects can impact business processes for extended periods. They find troubleshooting complex and note that enhancements or fixes rarely address longstanding issues promptly.

High and unpredictable costs

Managing Director

Moreover, the pricing structure for essential features such as payroll and profit and loss by jobs was not made clear upfront, leading to unexpected costs that strained our budget.

Sneaky contracts that will hook you with discounts and raise fees exorbitantly after your are stuck with your data and huge conversion costs.

68% of reviewers feel negative about NetSuite’s pricing. Users say subscription fees, customization, and add-on modules quickly increase overall costs, making the platform expensive for small businesses. Reviewers indicate that aggressive price hikes during contract renewals and unclear pricing for essential features cause budget strain. Some users report that scaling is difficult due to high per-user costs and frequent upselling. They find that implementation and technical support often require additional investment, and many functionalities are behind paywalls.

Remote access and scalability

Site Architect

Our use of NetSuite has eliminated the need for a lot of maintenance and support for our systems, as it is available in the cloud, and connects all enterprise networks to it, which helps us to constantly work remotely under all circumstances.

93% of reviewers feel positive about NetSuite’s cloud capabilities. Reviewers appreciate the platform’s real-time access from any device, which enables remote work and business continuity.

Systems Developer

I’ve worked extensively with the platform in implementing, supporting, and optimizing ERP solutions across multiple subsidiaries in the construction, retail, asset management, and manpower service sectors.

The real-time reporting and custom dashboards support faster, more confident decision-making. While setup and customisation require time and resources, the long-term gains in productivity and control make it worthwhile.

NetSuite is an accurate ERP system as long as the master data is clean and well-maintained, since the quality and reliability of its outputs heavily depend on having consistent, accurate, and properly managed data inputs across the organization.

It’s a robust and scalable ERP that centralises financials, reporting, and operations in one system, which significantly improves efficiency and data integrity.

The platform's real-time visibility through SuiteAnalytics and customizable dashboards empowers stakeholders to make data-driven decisions. While the initial implementation is resource-intensive, the long-term ROI is evident through automated processes and reduced manual entry.

What I value most is how NetSuite provides real-time visibility across business functions, automates critical workflows, and supports multi-entity financial management under one cloud system.

Senior Business Analyst

It provides excellent value for money for growing businesses that need to consolidate payment processing, data management, and financial reporting. While it requires an investment in training, the time-saving benefits and the reduction in manual errors make it a powerful asset for any data-driven team.

Management accountant

I like that it centralises key business processes such as finance, reporting, and operations, which makes day-to-day work more efficient and reduces the need to switch between multiple platforms.

Web Deisngner, Developer.

Powerful ERP software with a strong infrastructure that seamlessly integrates financials, inventory, and order management in one platform.
