Getting paid by a Self-Determination participant

Two different things are both called “vendoring”

This is the thing to get straight first, because searching for it will send you the wrong way.

Regional center vendorization is how a business becomes an approved provider under California's traditional service model. A regional center reviews you against a program design, assigns you a vendor number and a service code, and then refers people to you. It is a substantial process, it takes months, and the regional center decides whether it happens at all.

Getting set up with an FMS is what happens in the Self-Determination Program. A participant chooses you. Their Financial Management Services provider — the organization that holds and pays out their budget — collects some documents, checks a few things, and starts paying your invoices. It is paperwork rather than an application — nobody is deciding whether to let you in. How long it takes depends on the provider and on how quickly you send things back, so ask them for a timescale rather than assuming one.

Both get called “getting vendored” in conversation, including by people who work in this field every day. They are not the same thing and one does not lead to the other.

You do not need to be a regional center vendor

Nobody has to approve you onto a list before a participant can spend their budget with you. The participant chooses. That is the whole design of the program: the money follows the person, and the person decides who provides their services. There is one exception, for providers outside California, and it is a real one.

You also do not need a professional license unless your service is one that requires one. The waiver that governs this program explicitly provides for non-licensed, non-certified providers and commits the State to monitoring them — which is the machinery that lets a participant pay a gym membership, a guitar teacher or a riding school out of an SDP budget. If your service does require a license — nursing, speech, occupational or physical therapy, behavior services — you will be asked for it, and it will be looked up.

Who checks your qualifications, and how often

The waiver answers this in the same words under every service type it lists:

Entity Responsible for Verification: FMS and participant verify that the provider possesses the necessary license and/or certificate and meets other standards as applicable.

Frequency of Verification: Upon selection and annually thereafter through the IPP process.

California's 1915(c) Self-Determination waiver, Appendix C-1/C-3, Provider Specifications. The sentence appears 120 times — once for each service type in the program.

Two things follow from that, and they are worth knowing before you start.

It is the FMS that checks you, not the regional center. So the documents you are asked for, the form they come on, and how long it takes are that provider's, not the state's.

It happens again every year. Verification is not a one-off, so there will be something to do each year for as long as you are being paid. What that looks like — a form, a short recertification, a request for whatever has expired — is up to each provider. An FMS cannot keep paying against a qualification it can no longer verify, which is the reason to send a renewal in before anyone asks for it.

If you are outside California

This is the one place where somebody really does have to approve the arrangement, and it is worth knowing before you agree to anything.

California's stated policy is to serve its residents within the state. So before a regional center spends its funds on a provider located and doing business outside California, it has to ask DDS and get approval. That comes from Welfare and Institutions Code section 4519, and DDS set out how it works in instructions to regional center directors in November 2025. It applies to the Self-Determination Program explicitly: an out-of-state request has to include the participant's current person-centered plan, budget and spending plan.

What follows from it matters more than the rule itself:

• Virtual services count. A provider outside California delivering by video is in scope, not only one the participant travels to.
• Serving someone who is away does not count. If you are located and doing business in California and you provide a short-term or remote service to a participant who is temporarily out of state or traveling, no approval is needed. The test is where you are, not where they happen to be that week.
• You cannot start this yourself. The request goes from the regional center to DDS. Neither you nor the FMS can file it. The participant has to raise it with their service coordinator.
• It is not a formality. The regional center has to show the need cannot be met in California — what it did to find, develop or adapt an in-state service, and the results of a statewide specialist search it has to run first.
• Approval runs six months at a time. Longer than that needs a fresh assessment and a new request, and DDS is explicit that an earlier approval does not guarantee the next one.
• Border areas are different. For a non-residential service just over the state line, the regional center's own executive director can approve it without going to DDS.

The practical advice is short. If a participant asks you for something from outside California, tell them early that this needs DDS authorization through their regional center, and that it takes time. Starting work on the strength of a participant's enthusiasm is how out-of-state providers end up unpaid, and in this case the money cannot be released afterwards to fix it.

DDS, G-2025-Office of Statewide Clinical Services-001, “Instructions for Requesting Authorization for the Purchase of Out-of-State Services”, 18 November 2025, and Welfare and Institutions Code section 4519. The border-area exception is set out in a separate DDS letter, D-2025-Case Management-004, which we have not read.

Every FMS keeps its own list

There is no statewide list of approved SDP providers, and nothing you do with one FMS carries over to another. Each provider runs its own onboarding and keeps its own records, because each one is separately responsible for the checks above.

So if you are already set up with one FMS and a second participant comes to you whose budget is held somewhere else, you will go through it again with that provider. The same is true if you are already a regional center vendor: that tells an FMS nothing it is allowed to rely on, and you will still be asked for documents.

This surprises people, and it is reasonable to find it irritating. It is worth understanding why it happens rather than assuming somebody is being difficult: the FMS that pays you is the one answerable for having verified you, and it cannot discharge that by pointing at another organization's file.

What carries over, and what does not

Within a single FMS, the work is done once.

• A second participant at the same FMS does not mean starting again. Once that provider has you on file, you are on file. You may be asked for something specific to the new person — commonly a service agreement naming them, their rate and what you have agreed to do — but not the whole packet again.
• A participant who changes FMS does mean starting again, with the new one. If a family moves their budget, their vendors and their employees have to be taken on by the incoming provider before it can pay anybody. If you are already set up with that provider for someone else, this is quick. If you are not, it is the full process, and it has a deadline attached to it that is not yours.

That second case is the one that catches people out, so it is worth saying plainly: when a family switches, your payments do not follow automatically. If you hear that a participant is moving to a different FMS, ask them who it is and get in touch early. A gap here means invoices nobody can pay yet.

The practice described in this section — that onboarding is not repeated for further clients of the same FMS, that a per-participant service agreement may still be needed, and that a switch means being taken on afresh by the incoming provider — comes from the FMS that publishes this site, as of 30 October 2026. It is how the work goes rather than a rule you can cite at anyone. No FMS is obliged to do it this way, so ask the one you are dealing with.

Employee or business: the question underneath all of this

Before any of the paperwork, there is a question that decides which paperwork it is.

Some people providing services in this program are businesses: independent, setting their own rates and hours, invoicing, handling their own tax. Others are employees of the participant — working the participant's schedule, under their direction, clocking in and out. California law, not preference, decides which you are, and for personal care and respite the answer is usually employee.

This matters to you because it changes everything downstream: who withholds tax, who carries workers' compensation, whether you invoice or submit time. If you are not sure which you are, say so early rather than late. The difference is set out here.

What happens next

• What you will be asked for — the documents, the checks, and what to have ready before you start.
• Getting paid — what an invoice has to show, who approves it, and what cannot be paid for at all.

If your FMS does this differently

These pages try to separate two things that get mixed together. Some of what is here is required, by the waiver or by a DDS directive, and where that is so the page says which one — you can go and read it. The rest is how a given provider chooses to work: which forms, how often they re-check things, what they will do about work done before you were cleared. There is no single answer to any of that, and a page that gave you one would be making it up.

So where you see us say ask your FMS, it is not a hedge. It is the actual answer. The provider holding the budget decides, and the only reliable source is them.

If you run an FMS and something here misrepresents how you work, tell us and we will say so. We would rather publish “providers differ on this, and here is how” than a tidy page that is wrong for half its readers. Send it to info@sentinelfour.com.

The same invitation goes to providers of services. If you have been through this with an FMS and something here was not how it went, that is worth knowing too.
