TL;DR: The best managed IT services companies for accounting firms in the USA in 2027 offer accounting software support, cybersecurity, secure cloud hosting, data backups, and reliable IT support during tax season. Compare providers based on accounting software compatibility, security, response times, scalability, and pricing to find the right fit for your firm.

Running an accounting firm means managing sensitive financial data, meeting strict deadlines, and keeping clients' information secure. A slow accounting application during tax season, an employee locked out of a client file, or an unexpected system outage can quickly disrupt your work.

That's why choosing the right IT partner matters.

The best managed IT services companies for accounting firms do more than fix computers. They help protect client information, maintain accounting applications, support remote employees, and keep business operations running when technical problems arise.

However, not every managed service provider (MSP) understands the demands of a CPA firm. Some specialize in accounting software hosting, while others manage the entire IT environment, from employee devices and networks to cybersecurity and technical support.

This guide compares seven providers worth evaluating in 2027, highlighting their services, potential limitations, and the types of accounting firms they may suit best.

Best Managed IT Services Companies for Accounting Firms at a Glance

These providers are a research shortlist, not a statistically validated ranking of the seven best companies in the country. Compare their current offerings, pricing, service agreements, and customer evidence before making a final decision.

1. Rightworks

Best for: Accounting firms seeking accounting-focused cloud and IT services

Rightworks focuses on technology for the accounting profession, with offerings that include accounting application hosting, managed IT, and cybersecurity-related services.

This specialization can be valuable for firms that rely on accounting software throughout the workday. Instead of coordinating every technology issue with a different vendor, firms can evaluate a provider whose services are designed around accounting workflows.

Rightworks is worth considering if your practice wants to support remote employees, simplify application access, and manage its technology environment through an accounting-focused provider.

Key services to evaluate

• Managed IT services and cloud hosting

• Accounting application support

• Cybersecurity and security planning

• Remote access and cloud-based workflows

• Support for accounting technology environments

Potential limitation: Not every application, integration, or configuration is necessarily supported. Confirm compatibility with your accounting software, document management systems, and other business applications before signing a contract.

2. Cetrom

Best for: CPA firms that depend on hosted accounting applications

Cetrom specializes in cloud hosting and managed IT services for accounting and other professional-services organizations.

For a CPA firm with employees working from multiple locations, hosted applications can provide a consistent way to access accounting software without maintaining all the underlying infrastructure in-house.

Cetrom is worth comparing if your firm prioritizes application hosting, centralized management, and technical support.

Key services to evaluate

• Hosted accounting applications

• Managed IT and infrastructure services

• Cloud access for distributed teams

• Security and backup capabilities

• Technical support and maintenance

Potential limitation: Hosting an application is not the same as managing every aspect of your IT environment. Ask which services are included, which require separate agreements, and how application performance and recovery are handled during tax season.

3. Verito

Best for: Smaller accounting firms comparing managed IT and hosting costs

Verito offers cloud hosting and managed IT services, with published pricing information that can help firms begin comparing options.

This can be useful for smaller practices that want to understand potential costs before entering a sales process. Published pricing also provides a starting point for comparing bundled packages with arrangements that charge separately for hosting, security, support, or additional users.

Verito is worth evaluating if your firm wants to compare service packages and understand the costs of moving some or all of its IT environment to a managed arrangement.

Key services to evaluate

• Accounting software hosting

• Managed IT services

• Security-related services

• Backup and recovery

• Co-managed IT options

Potential limitation: A published starting price does not necessarily reflect the total cost of ownership. Check setup charges, user limits, storage allowances, optional security services, contract length, and migration costs.

4. Tabush Group

Best for: Accounting firms choosing between fully managed and co-managed IT

Not every accounting firm wants to outsource its entire IT operation. Some already have internal IT staff but need additional technical expertise, security support, or help managing day-to-day requests.

Tabush Group offers IT services for accounting and other professional-services firms, including fully managed and co-managed arrangements.

A co-managed model can be useful when internal IT staff understand the firm's operations but need outside support for monitoring, infrastructure, cybersecurity, or additional technical capacity.

Key services to evaluate

• Fully managed IT services

• Co-managed IT support

• Cloud and infrastructure services

• Technical support and maintenance

• Security and business continuity capabilities

Potential limitation: Co-managed IT works best when responsibilities are clearly defined. Establish who handles escalations, approves changes, manages security incidents, and takes ownership when an issue involves both internal and external teams.

5. Xvand Technology

Best for: Accounting firms seeking specialized IT support and secure remote access

Xvand Technology has an accounting-specific service offering covering managed IT and technology support for accounting firms.

For practices with remote employees, multiple offices, and business-critical applications, reliable technical support and secure access to client information are important considerations.

Xvand is worth evaluating if your firm wants to compare accounting-oriented IT support with broader managed IT service providers.

Key services to evaluate

• Managed IT support

• Accounting software assistance

• Secure remote access

• System updates and maintenance

• Cybersecurity and infrastructure management

Potential limitation: An accounting-specific service page does not establish the full depth of a provider's security capabilities. Ask about endpoint detection and response, monitoring hours, incident escalation, backup restoration tests, and documented response commitments.

6. Consilien

Best for: Accounting firms evaluating managed IT alongside security operations

Consilien provides managed IT and security-related services and has published comparisons of providers serving accounting firms.

Its offering is worth investigating if your practice wants to evaluate day-to-day IT management alongside cybersecurity and ongoing technology oversight.

When comparing providers, look beyond whether they advertise security services. Focus on the controls they implement, how incidents are handled, and what reporting and remediation support they provide.

Key services to evaluate

• Managed IT services

• Security monitoring and incident response

• IT infrastructure management

• Backup and business continuity

• Security planning and ongoing support

Potential limitation: Published rankings and service descriptions are not independent proof of superiority. Review the actual service agreement, request supporting documentation, and compare its capabilities with those of other providers.

7. Ntiva

Best for: Accounting firms with broader managed IT requirements

Ntiva is a broader managed IT services provider worth investigating when an accounting firm needs support across its wider business technology environment.

This may suit practices managing multiple offices, growing employee teams, complex networks, or a combination of cloud-based and on-premises systems.

However, general IT expertise does not automatically establish specialized experience with CPA firms. Verify that the provider can support your accounting applications and operating requirements.

Key services to evaluate

• Managed IT and help desk support

• Infrastructure and cloud management

• Cybersecurity services

• IT planning and technology improvements

• Backup and disaster recovery

Potential limitation: Ask for relevant accounting-firm references and confirm application compatibility, security responsibilities, and tax-season support arrangements before shortlisting Ntiva.

What Should Accounting Firms Look for in a Managed IT Provider in 2027?

When comparing managed IT services for CPA firms, focus on the capabilities that protect client data and keep daily operations running. A long service list matters less than whether the provider can meet your firm's actual requirements.

1. Cybersecurity and WISP Support

Accounting firms handle tax returns, Social Security numbers, payroll information, financial statements, and other sensitive records. Protecting this information requires more than basic antivirus software.

The IRS advises tax professionals to maintain a Written Information Security Plan (WISP). Depending on the firm's activities and applicable requirements, the FTC Safeguards Rule may also apply.

A managed IT provider can help implement security controls, monitor systems, maintain documentation, and support incident response. However, outsourcing IT does not automatically make a firm compliant.

Before signing a contract, ask whether the provider supports:

• WISP development, review, and maintenance

• Multifactor authentication and access controls

• Endpoint protection and security monitoring

• Software patching and vulnerability management

• Employee security awareness

• Incident response planning and documentation

For additional guidance, review the IRS's WISP guidance and the FTC Safeguards Rule guidance.

2. Accounting Software Compatibility and Cloud Hosting

Not all IT providers support the same accounting applications. Before moving systems or changing providers, confirm that the proposed solution works with your exact software versions, integrations, document management tools, printing requirements, and multi-user workflows.

If you are comparing accounting firm cloud hosting providers, look beyond the ability to access applications remotely. Ask about migration support, performance, software updates, backup arrangements, recovery procedures, and responsibility for application-related issues.

A hosting provider may manage the environment in which your software runs without managing every device, network, or security requirement across your firm. Make sure you understand where one service ends and another begins.

3. Busy-Season Support and Business Continuity

During tax season, a technical issue can quickly delay work and affect client deadlines. Your provider should understand the importance of timely support, reliable application access, and rapid recovery.

Ask prospective providers:

• What support hours are included in the contract?

• What are the guaranteed response and escalation times?

• Is technical assistance available during evenings and weekends?

• How are peak workloads and seasonal employees handled?

• How frequently are backups tested?

• What are the documented recovery time and recovery point objectives?

A promise of 24/7 support does not guarantee immediate resolution. Review the service-level agreement and ask how the provider handles major outages.

4. Remote Access and Employee Security

Accounting firms often support employees across multiple offices or remote locations. That creates challenges around access permissions, device security, and employee onboarding and offboarding.

Look for role-based access, multifactor authentication, device management, secure remote connections, and documented procedures for removing access when employees leave.

The provider should also explain how it responds to lost devices, compromised credentials, and suspected unauthorized access to client information.

5. Transparent Pricing and Clear Responsibilities

A low monthly fee may look attractive, but the real question is what the service includes. Compare the full cost of service, including:

• Per-user or per-device charges

• Hosting, storage, and backup costs

• Security monitoring and incident response

• Software licensing and migration

• After-hours support

• Setup fees and contract exit costs

If different vendors manage your network, accounting applications, and cloud infrastructure, establish a clear escalation process. You should know who owns each responsibility before an issue occurs.

How Much Do Managed IT Services Cost for Accounting Firms?

Managed IT pricing depends on the number of users and devices, software requirements, security needs, hosting arrangements, support coverage, and the complexity of the firm's IT environment.

Common pricing models include:

Request a written quote based on the same requirements from each provider. A higher-priced service may include broader security and recovery coverage, while a lower-priced package may leave important responsibilities to your firm.

Compare total annual costs, not just advertised monthly starting prices.

How to Choose the Right IT Provider for Your Accounting Firm

Before committing to a provider, use this checklist to compare your options.

• Does the provider support our accounting software and related applications?

• Can it help implement and maintain our WISP?

• Are security monitoring, incident response, and backup responsibilities clearly defined?

• Does the support agreement cover our operating hours and busy-season requirements?

• Are backup restoration and disaster recovery procedures documented and tested?

• Can the provider support our current offices, remote employees, and expected growth?

• Are pricing, contract terms, exclusions, and exit procedures transparent?

• Can it provide relevant customer references or verifiable experience with accounting firms?

Ask whether the provider uses managed IT services software to monitor systems, track support requests, manage security tasks, and report on service performance.

Final Verdict

Choosing the right managed IT provider means finding a partner that understands your applications, protects client information, supports your employees, and helps your firm recover when technical problems arise.

For accounting firms that also want broader business IT support, Tollanis Solutions offers managed IT services that can be evaluated for infrastructure management, technical support, cybersecurity, and technology integration. Firms should confirm accounting application compatibility, service coverage, and recovery requirements before deciding whether its capabilities match their needs.

Ultimately, choose the provider that fits your firm's technology environment, provides clear accountability, and can support your business as it grows.
