The IDD software market has more options than it did five years ago. More vendors, more features, more claims of being “purpose-built for IDD.” And more risk of making a costly platform decision based on a demo that showed the software at its best rather than how it behaves under your agency’s actual operating conditions.
A software vendor’s demo is designed to impress. Your evaluation process should be designed to find the gaps. These ten questions are the ones that experienced IDD agency administrators wish they’d asked before signing, and the ones that separate platforms that will genuinely work for your agency from platforms that will require constant workarounds.
Ask every vendor. Compare answers directly. The quality and specificity of a vendor’s responses tells you as much as the software itself.
Question 1: “Show me how data flows from a service visit to a submitted claim, every step, without staff intervention.”
Don’t accept a description. Ask for a live walkthrough: DSP checks in via EVV → service is documented in case management → authorization utilization updates → claim is generated and submitted. Then ask: at which steps does a staff member need to manually transfer or re-enter data?
This question reveals integration depth better than any feature comparison. If any step involves exporting from one module and importing to another, you’re looking at a platform of connected tools, not a truly integrated system. The practical difference is measured in staff hours every billing cycle.
With Vertex, EVV data flows automatically to billing. Case Manager is connected to authorizations and billing records. No manual transfer steps between modules.
Question 2: “How does your case management module connect to billing and service delivery?”
For IDD agencies, case management is not a documentation silo, it’s the operational center of service planning and delivery. ISP goals, service notes, progress reporting, and authorization tracking should all connect directly to billing and EVV records rather than existing as parallel documentation that staff maintain separately.
Ask vendors to show you specifically how a case note connects to a billed service, and how an authorization limit in the case management system affects what billing staff can submit. If the answer is “you’d reconcile those manually,” case management is a standalone module with a shared login, not an integrated system.
Vertex Case Manager is built as a core platform component. Eight features that transform IDD service delivery through integrated case management are worth reviewing before your vendor evaluation.
Question 3: “Does your platform handle vocational programs, piece-rate tracking, and client payroll?”
This question immediately identifies whether a vendor was built for the full scope of IDD service operations or for a narrower subset. Many agencies, including Goodwill organizations, sheltered workshops, rehabilitation facilities, and Arc affiliates, operate vocational programs alongside their direct service programs.
Piece-rate tracking, productivity-based wage calculation, and client payroll for individuals earning wages in vocational settings require functionality that most platforms don’t have. If your agency operates any vocational component, or may in the future, verify this capability specifically rather than assuming it’s included.
Vocational Time Manager and Client Payroll Manager are native Vertex modules designed for exactly this environment, including 14(c) compliance requirements.
Question 4: “How do your scheduling and workforce management tools connect to payroll?”
DSP scheduling, time and attendance, and payroll are operationally inseparable in an IDD agency, but they’re frequently handled by separate systems that require manual reconciliation between them. Ask vendors to walk you through what happens when a DSP works an unscheduled shift: how does that change flow from scheduling to time tracking to payroll without staff manually bridging the gap?
The answer tells you whether workforce management is genuinely integrated or whether payroll close still involves reconciling multiple data sources. Workforcehub Advanced connects scheduling and time tracking to payroll as a single data flow, not three separate systems that staff align manually each pay period.
Question 5: “Who maintains state-specific billing and compliance rules, you or us?”
This question cuts to a critical difference in IDD software products: whether state-specific rules for billing, EVV, and documentation are maintained by the vendor as part of the product, or by each agency as a configuration responsibility.
The right answer is the vendor. Agencies should not be tracking state regulation changes and updating their own billing configuration every time a state modifies its claim format, EVV enforcement threshold, or service documentation requirement. That’s a vendor responsibility, and in purpose-built IDD software, it’s handled as one.
Vertex maintains state-specific billing compliance for Wisconsin, Minnesota, Michigan, Indiana, Pennsylvania, North Carolina, Oklahoma, Kansas, and Arizona as a product responsibility. When a state updates its rules, that update is deployed to the platform, not assigned to agency staff as a configuration project.
Question 6: “What does your implementation process look like for an agency with our service types and size?”
Implementation is where platform decisions succeed or fail. A vendor who can describe a specific implementation process, including what data migration looks like, how staff training is structured by role, what go-live support includes, and what the typical timeline is for an agency your size, is in a different category from a vendor who answers with “it depends” and a general timeline range.
Ask specifically: How is billing staff training different from case manager training different from DSP training? What happens on day one after go-live? What support exists in the first 30–60 days if issues arise?
Vertex’s implementation support and Learning Center are designed specifically for IDD agency staff at every role level.
Question 7: “Can we talk to three agencies similar to ours that implemented your platform in the last 18 months?”
References matter more than demos. Ask specifically for agencies that are similar to yours in size, service types, and state, not the vendor’s best-case reference customers who happen to be larger and simpler than you. When you talk to references, ask them specifically about billing performance before and after implementation, what the implementation experience was actually like, and how the vendor responded when problems arose.
Vertex’s case studies include agencies like Ability Building Community, The Arnold Center, Lark Enterprises, and JCI, with specific detail on what changed operationally after implementation.
Question 8: “How does your platform handle financial management and reporting?”
IDD agencies, especially nonprofits, need financial reporting that integrates with operational data, not just a general ledger disconnected from service delivery. The ability to report on program-level revenue and cost, connect funding source performance to operational decisions, and produce the financial documentation that grant funders and boards require should be part of the platform, not a separate finance tool.
Vertex Financial Manager provides financial management designed specifically for IDD organizations, integrating financial data with the billing, payroll, and program data that operational reporting requires.
Question 9: “What does your product roadmap look like for the next 12–18 months?”
IDD service regulations, workforce management requirements, and EVV technology are all evolving. A platform that meets your needs today should also be investing in the capabilities you’ll need over the next few years. Ask vendors what they’re building, what problems they’re prioritizing, and how customer input shapes the roadmap.
This question also reveals how the vendor thinks about their product. Vendors with a clear, IDD-focused roadmap, new states being added, compliance updates being built, integration capabilities being expanded, are invested in the sector. Vendors with vague answers may be treating IDD as one vertical among many rather than a core market.
Question 10: “What is your total cost of ownership for an agency like ours, not just the license fee?”
The license fee is the most visible cost in a software evaluation. It’s rarely the whole story. Ask vendors to help you model the total cost of ownership: license fees, implementation costs, training, ongoing support, any fees for adding users or services, and the cost of any required integrations with third-party tools.
Then compare that against the current cost of your manual processes, staff hours spent on reconciliation, billing denials, payroll close time, and any compliance gaps that create audit exposure. The total cost of ownership calculation often looks very different from the license fee comparison, and it’s the only comparison that actually tells you what each option will cost your agency.
Vertex’s ROI framework for IDD agencies provides a structured approach to this calculation. Schedule a demo and ask us to walk through the numbers for an agency with your specific profile.
