Plain-English definitions of payments, split-payment, reconciliation and agentic-finance terms.

## Split payments & marketplace flow

- [Delayed capture](/glossary/delayed-capture/) — Delayed capture authorizes a card at checkout but takes the money later — holding the funds until the order ships, the job is done or the price is confirmed.
- [Destination charge](/glossary/destination-charge/) — A destination charge bills the buyer through the platform, then routes the money straight to the seller's connected account, minus the platform's fee.
- [Escrow (payments)](/glossary/escrow/) — In payments, escrow means holding a buyer's funds until an agreed condition is met — then releasing to the seller, or refunding cleanly if it falls through.
- [Flow of funds](/glossary/flow-of-funds/) — Flow of funds is the full path money takes through a platform — from the buyer's payment to every seller, partner, fee, and final settlement.
- [Held funds (reserve)](/glossary/held-funds/) — Held funds are money a platform withholds from a seller's balance for a set period to cover refunds, chargebacks or disputes before releasing it.
- [Marketplace payout](/glossary/marketplace-payout/) — A marketplace payout is the money a platform pays out to its sellers, contractors or partners after taking its own fee from each sale.
- [Marketplace wallet](/glossary/marketplace-wallet/) — A marketplace wallet is a stored balance a platform holds for each seller — earnings land in it and pay out on the platform's schedule, not on every sale.
- [Merchant of Record (MoR)](/glossary/merchant-of-record/) — The Merchant of Record is the legal entity that sells to the buyer, takes the payment and carries the tax, refund and chargeback liability for it.
- [Multi-party payment](/glossary/multi-party-payment/) — A multi-party payment is a single incoming payment that has to be divided among several recipients at once — multiple sellers, partners and the platform.
- [Payment facilitator (Payfac)](/glossary/payment-facilitator/) — A payment facilitator lets its own customers accept card payments as sub-merchants under its master merchant account, without each opening their own.
- [Payout schedule](/glossary/payout-schedule/) — A payout schedule is the rule that sets when a platform releases funds to sellers or partners — daily, weekly, on settlement, or on a custom trigger.
- [Platform fee](/glossary/platform-fee/) — A platform fee (or application fee) is the cut a marketplace keeps from each transaction — its take rate — deducted before sellers are paid out.
- [Revenue share](/glossary/revenue-share/) — Revenue share is an arrangement where the income from a transaction is split between parties by an agreed percentage rather than a fixed fee.
- [Separate charges and transfers](/glossary/separate-charges-and-transfers/) — Separate charges and transfers is a Stripe Connect model: the platform charges the buyer into its own balance, then transfers each seller's share out later.
- [Split payment](/glossary/split-payment/) — A split payment divides one incoming payment across several parties — sellers, partners and the platform's own fee — at the moment it settles.
- [Sub-merchant](/glossary/sub-merchant/) — A sub-merchant is a seller that accepts card payments under a payment facilitator's master merchant account instead of holding its own.
- [Take rate](/glossary/take-rate/) — A take rate is the percentage of each transaction a marketplace keeps as its own revenue after paying out sellers and partners.

## Reconciliation & cash

- [Accounts receivable aging](/glossary/accounts-receivable-aging/) — AR aging groups unpaid invoices by how overdue they are — current, 30, 60, 90+ days — so you can see which money is late and how badly.
- [Bank reconciliation](/glossary/bank-reconciliation/) — Bank reconciliation matches your accounting records against your bank statement, line by line, so the two agree and nothing is missing or double-counted.
- [Cash application](/glossary/cash-application/) — Cash application is the step of matching each incoming payment to the invoices it settles, so received money is applied to the right customer accounts.
- [Cash-flow forecast](/glossary/cash-flow-forecast/) — A cash-flow forecast projects the money coming in and going out over the weeks ahead, so you can see your cash floor before you hit it.
- [Chargeback](/glossary/chargeback/) — A chargeback is a forced reversal of a card payment, initiated by the buyer's bank rather than the merchant — the money is pulled back, often with a fee.
- [Days sales outstanding (DSO)](/glossary/days-sales-outstanding/) — DSO is the average number of days it takes to get paid after a sale — a single number for how fast invoices turn into cash.
- [Ledger vs sub-ledger](/glossary/ledger-vs-subledger/) — The general ledger holds summary totals; a sub-ledger holds the itemised detail behind one. Both must agree — the sub-ledger reconciles up to the ledger.
- [Partial payment](/glossary/partial-payment/) — A partial payment is when a customer pays only some of an invoice — leaving a balance that's easy to miss unless every payment is reconciled to what was owed.
- [Payment reconciliation](/glossary/payment-reconciliation/) — Payment reconciliation matches the money that actually arrived in your account against the invoices, orders and payouts it was meant to settle.
- [Remittance advice](/glossary/remittance-advice/) — Remittance advice is the note a payer sends alongside a payment, listing which invoices it covers — so the receiver can match the money to the right bills.
- [Three-way match](/glossary/three-way-match/) — A three-way match checks a supplier invoice against its purchase order and the goods-received note before you pay — three documents that must agree.
- [Unmatched transaction](/glossary/unmatched-transaction/) — An unmatched transaction is money that moved through your accounts but isn't tied to an invoice, order or ledger entry — so nobody yet knows what it was for.

## Money movement & cost

- [Cross-border payment](/glossary/cross-border-payment/) — A cross-border payment moves money between parties in different countries, usually across currencies and banking systems — slower and costlier than domestic.
- [FX markup](/glossary/fx-markup/) — FX markup is the margin a provider adds on top of the real exchange rate — a hidden fee baked into the rate itself, separate from any stated transfer charge.
- [Interchange fee](/glossary/interchange-fee/) — An interchange fee is the charge the merchant's bank pays the cardholder's bank on every card transaction — the biggest slice of accepting a card.
- [Least-cost routing](/glossary/least-cost-routing/) — Least-cost routing picks the cheapest rail for each payment — local schemes, SEPA, SWIFT or card networks — so fees and FX spreads don't eat the margin.
- [Mass payment](/glossary/mass-payment/) — A mass payment sends money to many recipients in one batch — hundreds of sellers, contractors or suppliers paid from a single instruction instead of one by one.
- [Mid-market rate](/glossary/mid-market-rate/) — The mid-market rate is the true midpoint between the buy and sell price of two currencies — the real exchange rate before any provider adds a markup.
- [Multi-currency account](/glossary/multi-currency-account/) — A multi-currency account holds and moves several currencies from one account — receive, keep and pay in each without converting through your home currency.
- [Settlement](/glossary/settlement/) — Settlement is the point where a payment is final and the money lands in the recipient's account — distinct from authorisation, which only reserves the funds.

## Payment methods & rails

- [ACH](/glossary/ach/) — ACH is the US Automated Clearing House network — a low-cost, batch-based rail for moving money between bank accounts, settling in one to two business days.
- [ACH vs wire](/glossary/ach-vs-wire/) — ACH vs wire compares two US payment rails: ACH is cheap, batched and reversible over a day or two; a wire is fast, same-day and final but costs far more.
- [Acquirer vs issuer](/glossary/acquirer-vs-issuer/) — The acquirer is the merchant's bank that collects card payments; the issuer is the cardholder's bank that funds them — opposite ends of one transaction.
- [BACS](/glossary/bacs/) — BACS is the UK's batch bank-transfer scheme behind Direct Debit and Direct Credit — cheap and reliable, but on a fixed three-day cycle, not real time.
- [CHAPS](/glossary/chaps/) — CHAPS is the UK's same-day, high-value payment scheme — money settles individually within hours and the transfer is final, at a higher per-payment cost.
- [Faster Payments](/glossary/faster-payments/) — Faster Payments (FPS) is the UK's real-time bank transfer scheme — money moves between accounts in seconds, any time of day, and is final once sent.
- [Instant payout](/glossary/instant-payout/) — An instant payout moves money to a recipient in seconds, any day of the week, using a real-time rail instead of a next-day bank transfer.
- [Merchant account](/glossary/merchant-account/) — A merchant account is a specialised bank account that holds card takings before they settle to your everyday account — a staging ground for money collected.
- [Open banking](/glossary/open-banking/) — Open banking lets licensed third parties access bank data and initiate payments — with the customer's consent — through regulated APIs, not screen-scraping.
- [Pay by bank](/glossary/pay-by-bank/) — Pay by bank moves money directly from the payer's bank account to yours over open-banking rails — no card, no card fees, no card network in between.
- [Payment gateway](/glossary/payment-gateway/) — A payment gateway captures a payment at checkout and passes it securely to the processor — the front door where card and account details are taken.
- [Payment link](/glossary/payment-link/) — A payment link is a shareable URL that opens a ready-to-pay checkout — no code, no invoice software — so you get paid by pasting it into an email or chat.
- [Payment processor](/glossary/payment-processor/) — A payment processor moves an authorised payment through the card networks and banks — the plumbing that gets money from the buyer's bank to yours.
- [Payment rail](/glossary/payment-rail/) — A payment rail is the network that moves money between accounts — ACH, wire, SEPA, Faster Payments or the cards — each with its own speed, cost and reach.
- [Payment service provider (PSP)](/glossary/payment-service-provider/) — A PSP bundles the gateway, processing, and often a merchant account into one service, so a business can take payments without wiring up each piece separately.
- [Push-to-card](/glossary/push-to-card/) — Push-to-card sends money straight to a debit card using the card networks, so a payout lands in seconds instead of waiting on a bank transfer.
- [Push-to-debit](/glossary/push-to-debit/) — Push-to-debit sends money straight to a debit card over the card networks, landing in seconds using an Original Credit Transaction rather than a bank transfer.
- [Real-time payments (RTP)](/glossary/real-time-payments/) — Real-time payments settle bank-to-bank in seconds, 24/7, with the money available and the transfer final instantly — schemes like the US RTP network and FedNow.
- [SEPA](/glossary/sepa/) — SEPA is the euro-zone scheme for cheap, standardised euro transfers across 36 countries — a domestic-style rail with SEPA Credit Transfer and Instant variants.
- [Stripe Connect](/glossary/stripe-connect/) — Stripe Connect is Stripe's product for platforms and marketplaces that need to onboard sellers, split payments and pay out to third parties.
- [SWIFT](/glossary/swift/) — SWIFT is the global messaging network banks use to instruct cross-border payments, passing instructions between correspondent banks that then settle the money.
- [Wire transfer](/glossary/wire-transfer/) — A wire transfer moves money bank-to-bank one payment at a time, settling same-day and irreversibly — fast and final, but the most expensive domestic rail.

## Agentic finance

- [Agentic finance](/glossary/agentic-finance/) — Agentic finance is finance run by AI agents that act on the money chain — routing payouts, reconciling books, chasing invoices — under rules a human sets.
- [Agentic payments](/glossary/agentic-payments/) — Agentic payments are payments an AI agent initiates and executes from an intent you set — deciding the rail, timing and amount within your rules.
- [AI bookkeeping](/glossary/ai-bookkeeping/) — AI bookkeeping is software that keeps the books itself — categorising, invoicing, matching and posting entries automatically, with a human reviewing exceptions.
- [Autonomous reconciliation](/glossary/autonomous-reconciliation/) — Autonomous reconciliation is AI matching every payment and payout to your books continuously — posting each as a journal entry with a confidence signal.
- [Financial control tower](/glossary/financial-control-tower/) — A financial control tower is one live view over all of a business's money — cash, payments, payouts and books — so you can see and steer the whole chain.
- [Financial operations (FinOps)](/glossary/financial-operations/) — Financial operations, or FinOps, is the day-to-day machinery of moving, tracking and reconciling a business's money — invoicing, payouts, cash and the books.
- [Money chain](/glossary/money-chain/) — The money chain is the full path a payment takes — from the buyer, through processors, fees and FX, to everyone owed a share, and where value leaks.

## Accounting & finance

- [Accounts payable](/glossary/accounts-payable/) — Accounts payable is the money a business owes its suppliers for goods or services already received but not yet paid for — its short-term bills.
- [Accounts receivable](/glossary/accounts-receivable/) — Accounts receivable is the money customers owe a business for goods or services already delivered but not yet paid for — invoices still outstanding.
- [Deferred revenue](/glossary/deferred-revenue/) — Deferred revenue is money a business has been paid for goods or services it hasn't delivered yet — a liability until the work is done.
- [Dunning](/glossary/dunning/) — Dunning is the structured process of chasing overdue invoices — a timed sequence of reminders that escalates until a customer pays.
- [GMV vs TPV](/glossary/gmv-vs-tpv/) — GMV is the total value of goods sold through a marketplace; TPV is the total value of payments processed. They overlap but measure different things.
- [Invoice vs receipt](/glossary/invoice-vs-receipt/) — An invoice is a request for payment sent before money changes hands; a receipt is proof of payment issued after — different documents, different jobs.
- [Job costing](/glossary/job-costing/) — Job costing tracks the true cost of a single job or project — labour, materials and overhead — so you know what each one actually earned or lost.
- [Net 30](/glossary/net-30/) — Net 30 is a payment term meaning the full invoice amount is due within 30 days of the invoice date — a standard trade-credit window.
- [Working capital](/glossary/working-capital/) — Working capital is current assets minus current liabilities — the cash a business has on hand to cover day-to-day operations.

## Compliance & onboarding

- [Anti-money laundering (AML)](/glossary/aml/) — Anti-money laundering (AML) is the laws and controls that stop criminal money moving through the financial system — the framework KYC and KYB sit inside.
- [Beneficial owner (UBO)](/glossary/beneficial-owner/) — A beneficial owner (UBO) is the real person who ultimately owns or controls a company — the human behind the entity, however many layers deep.
- [Know Your Business (KYB)](/glossary/kyb/) — Know Your Business (KYB) is verifying a company before it can transact — its legal existence, ownership and the people behind it, not just one individual.
- [Know Your Customer (KYC)](/glossary/kyc/) — Know Your Customer (KYC) is the checks a regulated business runs to verify a customer's identity before it lets them transact — proving who they are.
- [Strong Customer Authentication (SCA)](/glossary/strong-customer-authentication/) — Strong Customer Authentication (SCA) is a rule requiring two independent factors to confirm a payer — cutting fraud on European online payments.
