# Key concepts

> Core terms for payins, payouts, and treasury — written for operators and stakeholders, with pointers to developer docs.

## Collect (payins)

* **Payer** — The person or organization paying you (for example a policyholder). Used to group payment activity and reporting.
* **Payment request** — An instruction to collect a specific amount; it moves through statuses until it succeeds, fails, or is canceled.
* **Payment method** — Saved or collected card or bank details used to charge a payer, without you storing sensitive data yourself.

For implementation details, see the **[Collect](/developers/collect)** and **[Payment request lifecycle](/developers/payment-request-lifecycle)** developer guides.

## Disburse (payouts)

* **Payee** — Anyone you pay: agents, providers, members, vendors.
* **Payout method** — How that payee receives funds (bank account, wallet, and so on), validated for the destination country.
* **Payout** — A single outbound payment; **batch payouts** group many payouts for commissions or bulk runs.

See **[Sending your first payout](/guides/disburse/sending-your-first-payout)** for a Console-oriented walkthrough, and **[Batch payouts](/developers/batch-payouts)** when your team needs the API-focused developer guide.

## Treasury

* **Treasury account** — A balance in one currency used to fund payouts and receive transfers.
* **Settlement account** — Your external bank account linked to Acclaim for funding and withdrawals.
* **Virtual account** — Bank details that attribute inbound wires to a specific treasury account.

See **[Funding](/developers/funding)** for developer-oriented funding flows.
