How long to open bank accounts for 5 PCs?

Realistic timelines for opening bank accounts across multiple PCs in an MSO-PC structure, why generalist banks take 35 to 75 days, and what practices can do in parallel.

Most multi-PC groups discover the answer to this question the hard way: it takes longer than they planned for, unless they've seen opening a single new PC account in minutes rather than weeks (opens in a new tab), and the cash flow consequences arrive before the accounts do.

At a generalist business bank, opening accounts for a 5-PC structure runs 35 to 75 days. At a healthcare-native bank, the same setup is 5 to 10 days. The gap matters because every day without a working account is a day insurance reimbursements can't land, payer EFT enrollments can't be filed, and patient billing can't fund payroll.

Why generalist banks take 35 to 75 days

Generalist business banks treat each PC like a separate, unrelated business, the same pattern that breaks down as soon as a single-entity account stops fitting a growing group (opens in a new tab). Every entity goes through full onboarding from scratch:

• Documentation collection: articles of incorporation, EIN letter, beneficial ownership disclosures, operating agreement
• KYC review: 7 to 15 days per entity, often serialized rather than parallel
• Underwriting: deposit limits, ACH velocity caps, wire authorization. Each entity reviewed independently
• Account activation: routing numbers issued, debit cards mailed, online banking provisioned

For 5 PCs, that pattern multiplies. A bank with a 7-day per-entity timeline can take 35 days at minimum. Banks that don't run multi-entity onboarding in parallel can stretch to 75 days or more.

None of this includes payer EFT enrollment, which depends on having a working bank account first. Add another 30 to 60 days for payer enrollment after account activation.

Why healthcare-native banks take 5 to 10 days

Banking that onboards every entity in parallel (opens in a new tab) assumes MSO-PC from day one. The onboarding flow is designed for multi-entity structure rather than retrofitting a single-entity flow:

• Documentation: collected once for the MSO and reused (where legally permissible) across PCs. Beneficial ownership and KYC reviewed in parallel
• Underwriting: applied at the structure level, not the entity level, so deposit limits and velocity caps are set consistently across all PCs
• Account activation: all entities provisioned together, with consolidated dashboard access
• Payer EFT enrollment support: routing numbers and account documentation made available immediately so the practice can file payer enrollments in parallel with onboarding completion

Lemma's onboarding for a 5-PC group typically runs 5 to 10 business days. Adding a 6th or 7th PC later runs 2 to 5 days because the structure is already in place.

What to do during the gap

Whatever timeline your bank runs, a few moves shrink the practical impact:

• File payer EFT enrollments the moment routing numbers are available, even if accounts aren't fully activated. Most payers accept enrollment with a pending status
• Open virtual accounts for per-location attribution while waiting on the underlying entity accounts to clear
• Document intercompany flow expectations in the management services agreement before accounts open, following the step-by-step account setup checklist (opens in a new tab). Once accounts are live, sweep rules can be configured to match
• Avoid signing payer contracts on a timeline that assumes accounts are already open. Build buffer

What Lemma doesn't do: it doesn't fast-track payer enrollment with the carriers themselves, or replace the legal documentation work that has to happen for each PC. It removes the bank-side delay so payer enrollment can start sooner.
