# Enroll in EFT and ERA

> Every meaningful payer paying by ACH into the right account, sending 835s your systems ingest, with virtual card fees declined.

**Goal:** every meaningful payer paying by ACH into the right account, sending 835s your systems ingest, with virtual card fees declined.

**Your leverage:** HIPAA-covered payers must offer ACH EFT when you request it, with working trace-number reassociation (45 C.F.R. § 162.1602; [CAQH CORE](https://www.caqh.org/core/eft-era-operating-rules)). "We only pay by virtual card" is a default you can decline.

## The four doors

There's no single place to enroll. The [payer directory](/reference/payer-enrollment-directory) says which door each payer uses.

Aggregators default many payers to virtual card and bury the ACH election in settings or a fee-bearing "premium" tier. Choose standard ACH. It must be offered without percentage fees.

## The recipe

1. **Build the payer list from money, not memory.** Rank 12 months of deposits by dollars. Don't miss quarterly payers, workers' comp, and deposits descriptored ECHO/ZELIS/OPTUM.
2. **Gather the packet once:** legal name, TIN, Type 2 NPI, credentialed address, routing/account, voided check or bank letter, authorized signer.
3. **Work top-down by dollars, batched by door.** Per payer: EFT to the [designated operating account](/start-here/03-setting-up-your-banking), ERA to your clearinghouse (confirm the receiver ID with your PM vendor), and record the stated processing time.
4. **Elect ACH wherever a vendor offers VCC.** If a payer resists, cite 45 C.F.R. § 162.1602 and escalate to provider relations. It works.
5. **Track to verified, not submitted.** Done means: a real claim paid by ACH into the right account, its 835 arrived and posted, the two [reassociated](/concepts/eft-reassociation). Processing runs from days (Optum Financial: about 5) to 4+ weeks. Some verify by penny deposits, some by a call to your admin (EnrollSafe).

## Maintenance

Enrollments break silently: bank changes ([full playbook](/guides/switch-banks)), address or TIN changes, annual re-verifications, and payers migrating between payment vendors (which can silently reset you to VCC or check). The tell is a payer's deposits stopping or changing form. [Deposit-side reconciliation](/concepts/reconciliation) notices in days instead of months.

  **Lemma aside:** Lemma's onboarding team runs this whole process when practices move their banking: payer list from your statements, enrollments filed and chased, each tracked to a verified deposit ([getlemma.com](https://getlemma.com)).
