Therapy marketplace: paying 10,000 therapists every Friday

Therapy marketplaces run W2 plus 1099 networks at scale, the kind of load that specialty banking for behavioral health platforms (opens in a new tab) has to account for, and ACH cost adds up fast. Here is the payout architecture that holds at 10k providers without breaking your reconciliation.

The Friday problem

A therapy marketplace at scale runs the same operation every Friday: pay 10,000 providers. Some are W2 employees who need direct deposit. Most are 1099 contractors who get paid for the sessions they billed that week. Both expect their money by 5 PM local time.

At one bank that charges $0.25 per ACH and a $5 monthly maintenance per provider, 10,000 payouts a week is $130,000 of avoidable per-transaction cost a year, plus the back-office work of tracking which provider got paid for what. Most platforms run this on a Friday-morning script that breaks at least once a quarter.

The payout architecture that holds

Three components.

• Free ACH at scale. The whole economics of a therapy marketplace falls apart if every Friday batch costs $0.25 per provider, a cost gap laid out in a full breakdown of ACH versus wire versus check costs (opens in a new tab). Healthcare-native banks that charge $0 per ACH eliminate the line item entirely.
• Per-provider routing identifiers. Each provider has a stable payout account on file. Reconciling who got paid for what session means matching at the payment level, not at the platform level. Per-provider virtual accounts instead of separate bank accounts (opens in a new tab) (or just well-architected ACH metadata) handle this without per-provider account openings.
• A working capital reserve. Claims revenue from insurance lands on its own cadence. Provider payouts happen on yours. A reserve smooths the gap, the same approach that works for ABA providers billing across state Medicaids (opens in a new tab), and sweeps from claims accounts top it up as remits clear.

What changes for the operations team

Two things, immediately.

• Friday becomes boring. The payout batch runs automatically against the week's billable sessions. Provider-level reconciliation runs the same morning. Exceptions are flagged for the ops team in a queue, not in a panic.
• The financial close gets cleaner. Each provider's payout ties to a specific revenue line. Per-state taxes, per-modality cost-of-revenue, and per-provider gross margin all become accessible because the banking layer already tags them.

The number you should be tracking

Cost per provider payout. Pull your last 12 months: total banking spend on payouts (ACH fees, maintenance, exception handling) divided by total payouts processed.

Healthy at scale is under $0.05 per payout. Most therapy marketplaces benchmarked are at $0.15 to $0.40 because they're paying per-item ACH at a generalist bank. Cutting that number to under a nickel is mostly a banking choice, not an operations choice.
