Carillon ERP Is an Acumatica Alternative for Companies That Want More Control

Acumatica states that Acumatica Cloud ERP is sold exclusively through its partner channel and that Acumatica matches customers with one of its 350+ Value Added Resellers to deliver service from planning through deployment and ongoing support.

Acumatica’s own implementation-partner guidance says successful implementation depends as much on finding the right partner as finding the right software.

Acumatica’s public support materials state that its international network of experienced resellers helps customers with the evaluation, implementation, training, and ongoing support of Acumatica ERP. Acumatica’s Direct Support terms separately state that support plans do not include training, consulting, or implementation services, and that customers should contact their Acumatica partner for those services.

That makes partner evaluation a critical part of the Acumatica buying decision and should be considered as importantly as the software.

Buyers should consider the partner’s longevity, staffing depth, Acumatica certifications, industry knowledge, data-conversion experience, reporting capabilities, and documentation practices before committing to the relationship.

That matters because even Acumatica's optional direct "Premier" support does not offer implementation services including training, data conversion and other implementation services. Also be aware that Acumatica publicly states it utilizes a global workforce.

Although changing Acumatica partners is apparently possible, it is like starting over with someone who is likely not familiar with your business.

Carillon takes a more direct approach. Carillon ERP clients receive direct access, both on-site and via Microsoft Teams including voice, screen sharing, and text, to the United States-based team responsible for developing, implementing, and supporting the system.

Using screen sharing in Microsoft Teams, Carillon can provide support faster than a local Acumatica reseller can drive to your site.

Third-party Authorized Consultants may assist, but direct access to the Carillon support team is built into the client relationship and always available.

That difference matters over the life of the ERP system. Training, data conversion, reporting assistance, implementation services, configuration guidance, integrations, workflow, security, and ongoing support all depend on the capabilities and continuity of the people providing those services.

Acumatica’s current public licensing materials describe two primary models for Acumatica Cloud ERP: SaaS Subscription and Private Cloud Subscription. According to Acumatica’s public licensing materials, both models are subscription-based and grant use of Acumatica Cloud ERP for the life of the subscription.

Acumatica previously offered Private Cloud Perpetual licensing, but Acumatica’s April 2022 Licensing Guide states that Private Cloud Perpetual was no longer available for new sales effective April 1, 2022. Consequently, for new buyers, Acumatica’s generally available public licensing path is subscription-based rather than perpetual-use licensing.

Acumatica’s SaaS agreement reflects a term-based subscription commitment. The standard agreement states that the initial term is one year unless otherwise stated in the customer’s Acumatica Order Form, and that the agreement automatically renews for additional one-year terms unless otherwise stated in the order form. Acumatica’s FAQ also states that after the first year, customers may cancel Acumatica SaaS service at the time of renewal with a minimum of 30 days’ written notice.

Carillon provides a distinct alternative. For organizations prioritizing flexibility, Carillon’s SaaS license is month-to-month and can be canceled with 10 days’ notice. For organizations prioritizing long-term ownership, Carillon continues to offer a perpetual use license with a one-time upfront payment, granting the right to use the software permanently without mandatory ongoing SaaS subscription fees.

This distinction is important. When evaluating ERP software, a company is also choosing a long-term commercial framework. Carillon gives buyers a choice between a flexible SaaS model and a perpetual-use license. Acumatica’s current public materials direct new buyers toward subscription licensing.

At Carillon, we believe customers should choose the licensing model that aligns with their business strategy, cash-flow preferences, ownership philosophy, and long-term technology plan. Carillon’s goal is to retain customers through the continued value of the system, supported by the freedom of a licensing model that fits the customer’s specific needs.

With Carillon's SaaS license, the relationship is straightforward. A customer can opt out with 10 days' notice. When the SaaS license ends, there are no remaining SaaS license fees and no third-party financing obligation created by Carillon. If the customer chooses a perpetual license instead, the customer makes a one-time payment and receives the right to use the software permanently.

Acumatica's public SaaS agreement reflects a term-based subscription commitment. The agreement states that the initial term is one year unless otherwise stated in the customer's Acumatica Order Form, and that the agreement automatically renews for additional one-year terms unless otherwise stated in the order form.

Acumatica's SaaS agreement also states that termination for any reason other than Acumatica's uncured material breach does not relieve the customer of the obligation to pay all future amounts due. In other words, monthly billing, if offered, is not the same as month-to-month licensing.

That difference matters when evaluating ERP risk. A buyer should understand whether it can leave on short notice, whether fees remain due through the end of the subscription term, and whether the licensing model matches the company's tolerance for long-term contractual commitments.

In Carillon's view, ERP customers should know exactly what happens if they decide to stop using the system. Carillon's SaaS model gives customers a clear exit path, while Acumatica's public SaaS agreement reflects a term-based subscription commitment.

If you are an Acumatica customer who wants to move to Carillon but is still contractually obligated under an existing Acumatica agreement, Carillon will waive its SaaS license fee for the duration of your remaining Acumatica subscription term. You can begin implementing and using Carillon immediately - with no Carillon SaaS license fee - while you fulfill your remaining Acumatica obligation.

Acumatica's public SaaS agreement reflects a term-based subscription commitment. The agreement states that the initial term is one year unless otherwise stated in the customer's Acumatica Order Form, and that the agreement automatically renews for additional one-year terms unless otherwise stated in the order form. The agreement also states that termination for any reason other than Acumatica's uncured material breach does not relieve the customer of the obligation to pay all future amounts due.

Carillon's offer is designed to help companies move forward without paying two SaaS license fees at the same time. Professional services, data conversion, implementation support, training, report writing, and other services are available at standard rates. The waiver applies to the Carillon SaaS license fee only. It does not pay, assume, or cancel any obligation the customer may have to Acumatica, an Acumatica partner, or any other third party.

Carillon makes this offer because no business should have to delay a better ERP decision simply because an existing subscription term has not yet expired. If Acumatica is not the right long-term fit for your business - whether due to functionality, support structure, licensing, cost, implementation experience, or any other reason - Carillon wants to help you get unstuck.

To discuss your situation, contact us directly. Every circumstance is different, and we are happy to have that conversation.

When an Acumatica customer needs functionality that does not exist in the core product, that functionality may be developed as a customization. Acumatica's own documentation describes a customization project as "a set of changes to the user interface, configuration data, and functionality of Acumatica ERP" developed using the Acumatica Customization Platform.

That flexibility can be valuable, but it can also create long-term maintenance responsibility. Acumatica's documentation recognizes that customized instances require upgrade attention. Before upgrading a customized Acumatica instance to a new version, the Acumatica Customization Platform validates the compatibility of the code included in currently published customization projects with the application code of the update version. Acumatica also directs users upgrading between versions to review technical release notes for breaking changes.

Carillon works on a different principle. When a client needs functionality that does not yet exist and Carillon determines that the functionality belongs in the core product, Carillon builds it directly into the core system. The development cost is absorbed once, and the benefit becomes available as part of Carillon ERP rather than maintained as a separate customer-specific customization layer.

Carillon believes this model makes the product stronger over time. Each client engagement can improve the system for the broader customer base, and customers are not left managing a separate customization layer that must be reviewed, validated, and maintained through future upgrades.

For ERP buyers, the question is not whether customization is possible. The question is who owns the long-term maintenance burden. In Carillon's view, functionality that belongs in the ERP system should become part of the ERP system.

Carillon operates on a direct-data-access philosophy. Carillon ERP runs on Microsoft SQL Server 2025 and supports all editions of Microsoft SQL Server 2025. Carillon clients have direct access to their own ERP database using standard SQL tools. Carillon also supports SQL Server failover capabilities available in Microsoft SQL Server 2025, including Always On availability groups in editions that support them.

Carillon normally uses Windows Authentication for SQL Server database access. A Carillon user can receive SQL Server CONNECT rights individually or through membership in an Active Directory security group. Carillon also supports SQL Server Authentication, but it is rarely used because of the potential security risk. For Carillon Everywhere, Microsoft Entra authentication is used.

That means Carillon customers can design their SQL Server environment around their own availability, reporting, security, performance, and data-residency requirements. With Carillon, the customer controls where its Microsoft SQL Server database is located, including the country in which the database resides. Customers can connect reporting tools, analytics tools, Power BI, auditors, IT staff, and internal developers directly to the ERP database using standard SQL Server tools.

According to Acumatica’s published SaaS FAQ, Acumatica SaaS currently uses Microsoft SQL Server, but Acumatica SaaS no longer allows ODBC access and directs customers to Acumatica’s development platform APIs instead. Acumatica identifies reasons for that model, including avoiding the need to learn complex database structures, protecting system stability, reducing upgrade-maintenance risk, and enforcing security policies.

That SaaS limitation is easier to understand when viewed alongside Acumatica’s multitenant architecture. In Acumatica terminology, a “tenant” is a logical data partition inside an Acumatica application/database environment. According to Acumatica’s published documentation, multiple tenants can use the same Acumatica application instance, with each tenant having isolated data. Acumatica documentation also describes configurations where one Acumatica application instance can give multiple tenants web access to the same database.

In practical terms, multiple companies’ or tenants’ data can reside in one physical SQL Server database, with separation defined and enforced logically by Acumatica. In Carillon’s view, that represents a distinct data-control model from Carillon’s approach, where each customer has direct access to its own Microsoft SQL Server database.

Acumatica Private Cloud is different from Acumatica SaaS. Based on Acumatica’s public licensing documentation, Private Cloud Subscription customers may deploy and manage the software on their own premises, through their own physical servers, or have the software hosted or managed by a VAR or third party. In that model, database and infrastructure access may depend on how the customer, VAR, or hosting provider configures and manages the environment.

Acumatica has publicly announced support for SQL Server 2025. However, we were unable to determine from Acumatica’s public documentation which editions of Microsoft SQL Server 2025 Acumatica supports.

For ERP buyers, the issue is not just whether the system stores data in SQL Server. The issue is whether the customer has direct, standard access to its own ERP database without depending on a SaaS API-only access model, application-enforced logical separation in a shared database architecture, or deployment-specific access arrangements. In Carillon’s view, ERP data should be directly accessible to the customer in a database format the customer’s own IT team, analysts, auditors, and reporting tools can use.
