Vendor Payment

Managing vendor payments in Self-Determination requires accuracy, timeliness, and strict alignment with authorizations. At Sentinel Four, we make sure vendors are set up correctly from the start and paid on schedule, so services can continue without interruption. All of our vendor payment services are provided exclusively for families in the Self-Determination Program (SDP).

What We Do

We handle vendor payments and purchasing strictly within the Self-Determination Program (SDP). Families choose providers; we make sure every dollar is authorized, documented, and paid on time—without surprises.

  • Vendor onboarding: W-9/ACH collection, remit details, verification
  • Invoice intake & validation against service codes, rates, dates, and authorizations
  • Payment processing on a predictable schedule (ACH or check)
  • Virtual credit cards (when appropriate) for secure, trackable purchases
  • Full recordkeeping and 1099 issuance where required
