One entity: separation by purpose
Operating, tax reserve, savings. Two disciplines make it work: threshold sweeps (define a target operating balance, move the excess on a schedule) and percentage tax funding (a fixed share of collections, rate set by your CPA).Multiple entities: separation by law
The moment you own two PCs, or an MSO and a PC, structure stops being preference. Each entity has its own accounts. Money crosses entity lines only as documented transfers: management fees per the MSA, loans with notes, distributions per the operating agreements. Pooling a PC’s revenue “for convenience” undermines the corporate separateness the whole MSO-PC structure depends on. Watch the enrollment detail: each payer EFT must point at the right entity’s account. Cross-entity enrollment errors are common and painful.Yield and insurance
Groups accumulate real balances, and the defaults are bad: near-zero interest and $250k FDIC per bank per depositor (FDIC). Options in order of effort: accounts that pay market rates, sweep networks that spread deposits across many insured banks, Treasury ladders for long-idle cash. Sweeps move freely within an entity, but across entities only on documented rails.Controls that scale
Dual approval above a threshold. Role-based access per entity. Issued cards with limits and merchant controls instead of a shared debit card. Audit trail on every movement. Configure it on day one instead of after an incident.Lemma aside: this is Lemma’s native shape: per-entity accounts in one dashboard, rule-based sweeps, approval workflows, and yield with expanded FDIC coverage (getlemma.com).
