TL;DR
- CCH ProSystem fx Tax is a Windows desktop application. Wolters Kluwer does not provide managed cloud hosting for the on-premise version. To get remote access, you need an independent hosting provider.
- You keep your existing Wolters Kluwer license. The hosting provider supplies the server, security, and infrastructure. Your workflow, your integrations, and your client data stay exactly as they are.
- Independent hosting supports the full CCH ProSystem fx suite, including Engagement, Fixed Assets, Scan, and Practice Management, as well as Thomson Reuters tools like Workpapers CS and Practice CS, all on one server.
- The five providers covered here are Verito, Ace Cloud Hosting, OneUp Networks, Cetrom, and Cloudvara. They differ on server architecture, compliance depth, pricing flexibility, and integration support.
- Hosting ProSystem fx independently is NOT the same as migrating to CCH Axcess. It gives your firm cloud access NOW, without forcing a platform decision you may not be ready to make.
You already know ProSystem fx. You have built workflows around it, trained your staff on it, and integrated it with other tools your firm depends on. The problem is that it lives on a local server or a desktop workstation, and getting remote access to it has never been straightforward.
Most ProSystem fx users assume Wolters Kluwer handles the cloud piece, the same way they handle software updates and support. That assumption is understandable, and it is wrong. Wolters Kluwer licenses ProSystem fx.
They do not operate a managed hosting environment for the on-premise version of the software. If you want ProSystem fx running in the cloud so your team can access it from anywhere, you need a third-party hosting provider to supply the server infrastructure. Your license comes with you. The provider builds the environment around it.
There is also a second thing most firms miss: independent hosting and migrating to CCH Axcess are two completely different decisions. Wolters Kluwer has been actively pushing firms toward CCH Axcess as the cloud-native path forward.
That migration is real, and for some firms it makes sense. For others, it means retraining staff, rebuilding workflows, and absorbing disruption mid-season. Independent hosting gives you a third option: get remote access to ProSystem fx now, on your terms, and evaluate CCH Axcess when you are actually ready.
This post covers five providers that make that possible, what separates them, and how to choose the right one for your firm.
What “ProSystem fx Hosting” Actually Means (And What Wolters Kluwer Does Not Provide)
Independent ProSystem fx hosting means a third-party provider installs your licensed copy of ProSystem fx on a cloud server, then gives your team secure remote access to it from any device. Wolters Kluwer remains your software vendor. The hosting provider manages the server.
Your existing Wolters Kluwer license stays active. Nothing about your software subscription changes. The hosting provider does not resell ProSystem fx. They supply the infrastructure: the server, the storage, the security controls, the backups, and the support when something stops working at 9 PM on April 14th.
Access works through a secure remote desktop connection. No VPN required from most providers. Your team logs in from a laptop, tablet, or phone, and ProSystem fx opens exactly as it would in the office. Files are stored on the hosted server, not on local machines, so version conflicts and emailed attachments disappear.
Which CCH ProSystem fx Modules Can Be Hosted?
The full CCH ProSystem fx suite can be hosted in an independent cloud environment. That includes:
- ProSystem fx Tax (the core tax preparation application)
- ProSystem fx Engagement (workpaper management for audit and compilation)
- ProSystem fx Fixed Assets
- ProSystem fx Scan
- ProSystem fx Practice Management
All of these modules run on the same server. Your integrations between them work exactly as they do on-premise. Providers like Cetrom and Ace Cloud Hosting explicitly list these modules in their supported application libraries, so there is no guessing involved.
What About Workpapers CS and Practice CS?
Some ProSystem fx firms also run Thomson Reuters applications alongside their CCH suite. Workpapers CS and Practice CS are common examples.
Good hosting providers support multi-application environments on a single dedicated server, meaning your ProSystem fx Tax installation and your Thomson Reuters tools can live in the same hosted workspace.
You do not need separate logins, separate servers, or separate vendor relationships. Confirm this explicitly with any provider you evaluate, but the capability exists and it is standard among the providers in this post.
Why ProSystem fx Firms Are Looking at Independent Hosting Right Now
The core reason is practical: remote and hybrid work is now the default for most professional services firms. Firms that stayed on local servers through 2020 and 2021 have been absorbing the friction ever since, whether that is staff driving into the office to file, partners unable to cross-check returns while traveling, or seasonal employees who cannot connect reliably from home.
There is also a second reason that fewer people talk about openly. Wolters Kluwer has been pushing ProSystem fx users toward CCH Axcess. Their migration page notes that CCH Axcess uses the same calculation engine and offers the same comprehensive library of forms as ProSystem fx, framing the migration as a low-disruption upgrade.
For some firms, that is accurate. For firms that have built years of custom workflows, staff preferences, and integrations around ProSystem fx, the migration is a bigger lift than Wolters Kluwer’s messaging suggests.
Independent hosting does not reject CCH Axcess as a future option. It separates the infrastructure decision from the software decision. A firm that hosts ProSystem fx with Verito or Ace Cloud Hosting today can still migrate to CCH Axcess next year, during a planned off-peak window, with adequate time to train staff.
What hosting does is remove the pressure of making that decision right now, under time constraints, without a full evaluation.
Three situations where independent hosting makes the most sense:
- Firms mid-season. No firm should be making a platform migration between January and April. Hosting ProSystem fx independently gives you remote access immediately without touching your software stack.
- Firms with complex integrations. If your ProSystem fx installation connects to Engagement, Fixed Assets, and third-party practice management tools, rebuilding those connections in CCH Axcess takes planning time you may not have.
- Firms that want contract flexibility. Most independent hosting providers offer month-to-month terms. If you later decide to migrate to CCH Axcess, you are not stuck in an annual hosting contract.
5 CCH ProSystem fx Cloud Hosting Providers
Each provider below supports ProSystem fx Tax in a hosted cloud environment. They are evaluated on server architecture, uptime commitment, support quality, compliance coverage, and pricing transparency. One note that applies to all five: you must hold a valid Wolters Kluwer license for ProSystem fx. No hosting provider sells the software itself.
1. Verito
Good for: Tax firms that want dedicated private servers, month-to-month terms, and IRS-aligned compliance built into every plan.
Verito is the option built specifically for tax and accounting firms. Their VeritSpace product hosts ProSystem fx Tax on dedicated private servers. “Dedicated” here has a specific meaning: your firm’s server is not shared with any other clients.
No shared resources, no performance degradation when other firms on the platform are filing at the same time.
The infrastructure sits in U.S.-based data centers with 100% uptime backed by a service level agreement (SLA), not just a marketing claim. Verito has maintained that uptime record since 2016. The average support response time is under 60 seconds, with 92% of issues resolved on the first call without escalation.
What separates Verito from most competitors is that compliance is standard, not an add-on. Every plan includes FTC Safeguards Rule alignment, IRS Publication 4557-compliant MFA and encrypted storage, SOC 2 Type II-audited infrastructure, 60-day automated backups (90-day on the Elite plan), and written information security plan (WISP) support.
Firms that want hosting and managed IT under one contract can bundle both through Verito’s Bundle plan. For a tax firm with federal compliance obligations, this matters more than it might seem. Providers that treat compliance as a premium feature are pushing that responsibility back onto your firm.
ProSystem fx Tax runs alongside Engagement, Fixed Assets, Scan, and connected applications including Workpapers CS and Practice CS in the same dedicated environment. No separate server is required. Migration is free and fully handled by Verito’s team, with most firms being fully migrated with zero downtime in 24–48 hours.
On the CCH Axcess question: Verito gives your firm the infrastructure to stay on ProSystem fx for as long as that decision makes sense. There is no Wolters Kluwer timeline built into the contract. Month-to-month terms mean you can migrate whenever you choose.
Pricing:
- Essentials: $69 per user per month (10GB RAM, 40GB storage, 2 apps included)
- Pro: $99 per user per month (15GB RAM, 100GB storage, 6 apps included)
- Elite: $149 per user per month (unlimited RAM, 150GB NVMe storage, unlimited apps)
- One-time setup fee: $200 per server
- 15-day free trial available, no credit card required
2. Ace Cloud Hosting
Good for: Firms running a mixed CCH and Thomson Reuters software stack on one server.
Ace Cloud Hosting has one of the most comprehensive supported-application libraries in this category. They host the full CCH ProSystem fx suite AND the full Thomson Reuters CS Professional Suite, including UltraTax CS, Practice CS, Workpapers CS, FileCabinet CS, GoFileRoom, and Fixed Assets CS.
For a firm running ProSystem fx Tax alongside any Thomson Reuters tools, Ace Cloud Hosting can consolidate everything onto one server with one support relationship.
Their ProSystem fx hosting carries a 99.99% uptime SLA and runs on SSAE-16 certified, SOC 2-compliant data centers. They hold ISO/IEC 27001, ISO 20000, ISO 27017, and ISO 27018 certifications, which is a deeper compliance documentation stack than most competitors.
Ace Cloud Hosting has won the “Outsourced Technology Provider” award from CPA Practice Advisor readers twice in consecutive years.
A 7-day free trial is available. Pricing is quote-based for ProSystem fx configurations. Contact them directly for a firm-specific number.
3. OneUp Networks
Good for: Firms actively weighing the ProSystem fx vs. CCH Axcess decision and wanting hosting infrastructure that works either way.
OneUp Networks positions itself as a CCH-first hosting provider and builds their ProSystem fx environment specifically for multi-user concurrent access. If your firm has five or more staff accessing ProSystem fx simultaneously during filing season, this focus on concurrent workload performance is worth attention.
They also host CCH Axcess, which makes them a logical option for firms in transition. You can host ProSystem fx with them now and move to Axcess later without changing hosting vendors. Their 15-day free trial has no credit card requirement, and terms are month-to-month. Pricing starts at a promotional rate for new customers; full pricing is quote-based.
OneUp Networks is a third-party provider with no affiliation with Wolters Kluwer. Your CCH licenses stay with you.
4. Cetrom
Good for: Mid-sized accounting firms that want a white-glove setup, dedicated account management, and cross-suite CCH and Thomson Reuters compatibility on one server.
Cetrom is a Washington D.C.-based provider that serves accounting firms with cloud hosting and managed IT in a bundled model. Their supported application list covers ProSystem fx Tax, Engagement, Practice Management, Scan, and Thomson Reuters Workpapers CS. Cross-suite compatibility is confirmed.
Cetrom takes a white-glove approach to setup and assigns dedicated account managers to clients, which appeals to mid-sized firms that want a single point of contact across their technology stack. They have a longer operating history than some newer providers in this space.
One honest note: Cetrom’s infrastructure is older relative to providers like Verito, and their compliance documentation is less prominently published than Ace Cloud Hosting’s. Firms with strict FTC Safeguards Rule or IRS Publication 4557 obligations should ask specifically about their controls before signing. Pricing is quote-based.
5. Cloudvara
Good for: Smaller firms and solo practitioners looking for a lower-cost entry into ProSystem fx cloud hosting.
Cloudvara offers dedicated server hosting for ProSystem fx Tax with remote desktop access and compatibility with connected applications including QuickBooks and Drake. Their model is straightforward: get ProSystem fx off your local machine and into the cloud at a price point accessible to solo practitioners and small practices.
The tradeoff is depth. Cloudvara’s published compliance documentation is less detailed than Verito’s or Ace Cloud Hosting’s, and their support infrastructure is smaller. For a solo practitioner or a firm with two to five staff that primarily needs remote access and is comfortable managing compliance independently, Cloudvara is a cost-effective starting point.
For firms with multi-user workloads, complex integrations, or strong compliance requirements, a provider higher on this list is the better fit.
Pricing is quote-based. Contact them directly for a firm-specific rate.
How to Choose the Right ProSystem fx Hosting Provider
The decision comes down to four questions. Answer these before you request a demo or quote from any provider.
Dedicated vs. Shared Servers: Ask the Specific Question
The single most important infrastructure question is whether your server is fully isolated or shared with other clients. Shared hosting performs adequately under normal load. Tax season is not normal load.
When all clients on a shared platform are filing simultaneously, shared infrastructure creates bottlenecks that show up as slow save times, lag during form calculations, and dropped sessions. Dedicated servers eliminate this at the infrastructure level.
Ask any prospective provider directly: “Is my firm’s server fully isolated, or are server resources shared with other clients?” If the answer involves phrases like “virtual environment” or “partitioned resources” without a clear commitment to dedicated allocation, that is shared hosting with different language.
What Applications You Need on One Server
Map out everything your firm runs before talking to a provider. If you use ProSystem fx Tax alongside Engagement, Fixed Assets, Practice Management, or Thomson Reuters tools like Workpapers CS or Practice CS, you need all of those applications confirmed on one server before you sign. Running your software stack across two separate hosting environments means separate logins, separate data locations, and coordination overhead that compounds during tax season.
Providers like Ace Cloud Hosting and Cetrom explicitly list cross-suite support in their application libraries. Verify this in writing for your specific software combination.
Contract Terms and Your Migration Timeline
Most independent ProSystem fx hosting providers offer month-to-month terms. This is important specifically because it decouples your hosting decision from your software roadmap.
If you move to CCH Axcess in 18 months, month-to-month hosting means you are not paying for a server you no longer need. Avoid providers that require annual or multi-year commitments before you have run a complete tax season on their platform.
Compliance Coverage Built Into the Base Plan
ProSystem fx users are tax professionals operating under the FTC Safeguards Rule and IRS Publication 4557. These are federal requirements, not optional practices. Confirm the following before signing with any provider:
- MFA is included, not an add-on
- Automated backups are included and meet IRS data retention standards
- SOC 2 certification covers the infrastructure your firm’s data lives on
- WISP documentation support is available if an auditor requests it
Providers that position compliance features as premium tier upgrades are making you pay to meet your federal obligations. That cost belongs to the provider, not to your firm.
ProSystem fx Hosting vs. Migrating to CCH Axcess: The Decision Nobody Explains Clearly
This is the question sitting behind every ProSystem fx hosting search, and no SERP result addresses it directly. Here is the actual comparison:

Wolters Kluwer’s roadmap |
Wolters Kluwer’s official migration documentation notes that CCH Axcess uses the same calculation engine as ProSystem fx and that most migrations complete within one day, with support for up to seven years of tax return history.
For firms with clean data and simple workflows, that framing may be accurate. For firms with deeply integrated CCH suites, custom workflows, and staff trained on ProSystem fx’s specific interface, “one day” is the data transfer estimate, not the full transition cost.
The most disruptive migrations happen under time pressure. Firms that move to CCH Axcess mid-season or with fewer than 60 days of preparation consistently report more disruption than those that plan migrations during a defined off-peak window.
Independent hosting removes the time pressure entirely. You get cloud access now. You evaluate Axcess when you have the capacity to do it properly.
FAQ
Can I access ProSystem fx in the cloud without switching to CCH Axcess?
Yes, completely. Wolters Kluwer does not provide managed cloud hosting for the on-premise version of ProSystem fx. Independent hosting providers supply the server infrastructure, and you bring your existing Wolters Kluwer license.
The software runs on the provider’s dedicated server, and your team accesses it remotely through a secure connection. Your CCH license, your data, and your workflow all stay unchanged. Moving to cloud access through an independent host is a separate decision from migrating to CCH Axcess, and one does not require the other.
Which hosting providers actually support CCH ProSystem fx?
Verito, Ace Cloud Hosting, OneUp Networks, Cetrom, and Cloudvara all host ProSystem fx Tax in a cloud environment. Among these, Verito and Ace Cloud Hosting have the most detailed ProSystem fx-specific documentation and the most clearly published compliance postures.
OneUp Networks explicitly builds their environment for multi-user CCH workloads. Cetrom supports cross-suite CCH and Thomson Reuters compatibility. Cloudvara is the most accessible option for smaller firms at lower price points.
Can I host ProSystem fx Engagement alongside ProSystem fx Tax?
Yes. ProSystem fx Engagement, Fixed Assets, Scan, and Practice Management can all run on the same hosted server as ProSystem fx Tax.
This preserves the integrated workflow you already have. Providers including Cetrom and Ace Cloud Hosting explicitly list Engagement and Practice Management in their supported application libraries. Confirm your specific module combination in writing before signing with any provider.
I am worried about a hosting provider having access to my client data. Is that a legitimate concern?
It is a reasonable question, and the answer depends on the provider’s architecture. With shared hosting, your data lives on the same physical infrastructure as other clients’ data, separated only by software controls.
With dedicated private server hosting, your environment is fully isolated. Providers like Verito use what they call Dedicated-Isolation Architecture, meaning no shared resources at any layer. Your data does not share a server with any other firm.
All reputable providers in this category also implement AES-256 encryption at rest and in transit, MFA on all access, and automated backups. Ask any prospective provider specifically whether your server is shared or isolated, and request documentation of their encryption and access control practices.
What happens to my ProSystem fx setup if I later decide to migrate to CCH Axcess?
Your independent hosting arrangement ends when you complete the migration. Wolters Kluwer’s migration utility supports up to seven years of tax return history for clients active within the last three years, and their implementation team handles the data transfer.
With month-to-month hosting terms, you are not paying for infrastructure you no longer need after migration. The hosting provider’s role simply concludes. Nothing about using an independent host today prevents or complicates a CCH Axcess migration later.
Is my firm required to have a WISP if I host ProSystem fx in the cloud?
Yes, and that requirement exists regardless of whether you are on-premise or cloud-hosted. The FTC Safeguards Rule classifies tax and accounting firms as financial institutions under the Gramm-Leach-Bliley Act, requiring a written data protection program. IRS Publication 4557 mandates a Written Information Security Plan (WISP) as a condition of maintaining a valid PTIN.
Cloud hosting does not create the obligation; it existed before you considered hosting. What good cloud hosting does is provide technical controls (MFA, encryption, automated backups) that satisfy the WISP’s required safeguards. Providers like Verito include WISP documentation support as a standard offering.
Do I need a new Wolters Kluwer license to move to hosted ProSystem fx?
No. Your existing ProSystem fx license transfers to the hosted environment without modification. Hosting providers are not Wolters Kluwer resellers. They supply infrastructure only. You continue purchasing, renewing, and supporting your CCH license directly through Wolters Kluwer. The only new cost is the hosting fee from your chosen provider.
Conclusion
The core insight from this comparison is simple: ProSystem fx and cloud access are not mutually exclusive. Wolters Kluwer may be pushing toward CCH Axcess, but the infrastructure decision and the software decision are yours to make independently, on your timeline.
If your firm is ready for cloud access but not ready for a platform migration, independent hosting is the practical answer. Verito is the option with the strongest combination of dedicated server architecture, IRS-aligned compliance on every plan, and month-to-month flexibility.
Ace Cloud Hosting is the right fit if your firm runs a mixed CCH and Thomson Reuters software environment. OneUp Networks makes sense if you want infrastructure that works whether you stay on ProSystem fx or eventually move to Axcess.
Cetrom fits mid-sized firms that want managed IT alongside hosting. Cloudvara is the accessible starting point for solo practitioners and small practices.
The firms that move through tax season most cleanly are the ones that made their infrastructure decisions in the off-season, without deadline pressure. That window is open now.
