The short answer
A hold delays payment of some or all of your card sales; a reserve keeps a pool of your funds set aside to cover future obligations. Visa's Core Rules (18 April 2026) say an acquirer must pay merchants promptly after deposit, less credits, discounts, disputes, agreed fees and merchant reserve funds, if applicable, accumulated to guarantee the merchant's obligations. The rules do not set reserve sizes or hold lengths; your merchant agreement does. Holds usually follow something that looks like new risk: an unusually large sale, a volume spike, rising disputes, or orders delivered well after payment.
Why providers hold money at all
When a cardholder disputes a charge, the money flows back through the system to the acquirer, which recovers it from the merchant. Visa's rules let the acquirer take that back out of what it pays you: Section 1.5.6.2 says acquirer payments to merchants must equal the transaction totals less credit transactions, applicable discounts, disputes, other agreed fees and merchant reserve funds where applicable. If the merchant cannot cover the amount, the acquirer carries the loss. That is why Visa's rules require an acquirer, on Visa's request and within 5 business days, to describe the collateral it takes against Visa-related positions with merchants, the exact collateral volumes it keeps for potential dispute exposure, in particular for future service merchants, and any process for withholding funds from an entity it believes cannot meet its Visa obligations, provide a future service, or is facing insolvency.
Hold versus reserve
A hold is usually event-driven: a batch or a set of transactions is paused while the provider reviews it, then released or kept against disputes. A reserve is usually a standing arrangement written into the agreement. Common structures include a percentage of each deposit kept for a period, a fixed amount built up before full funding, or an upfront amount. We are not quoting typical percentages or durations because the public network rules we checked do not publish them; they are set provider by provider. Read the reserve clause for four things: how the amount is calculated, when each portion is released, what can trigger a change, and how long funds are kept after the account closes.
What usually triggers a hold
Providers compare what you are doing now with what you told them at application and what you normally do. Visa's rules, for example, require acquirers to track daily gross sales volume, average transaction amount, transaction count and disputes for high-integrity risk merchants and compare them against normal daily activity. Anything that departs sharply from that pattern invites a review: a single sale far above your stated maximum ticket, a sudden jump in volume, a run of card-not-present sales from a business that usually swipes cards, a rise in disputes, or taking payment for goods or services delivered weeks or months later.
Getting a hold released
Ask the provider three questions in writing: which transactions are held, what specifically raised the concern, and what documents will close the review. Then send everything at once: invoices, proof of delivery or tracking, customer contact details, contracts or signed work orders for large jobs, and an explanation of any volume change. Illustrative example only, with made-up round numbers: a contractor that normally runs $2,000 sales takes a single $40,000 deposit for a kitchen job. A signed contract, the customer's contact details and the project start date answer most of the provider's questions in one message. Once funds are released, they still travel as bank payments; Nacha notes that payments settle when the Federal Reserve's settlement service is open, which currently excludes weekends and federal holidays.
The rules name the tools, not the amounts
Visa's rules treat fund-holding as a risk-reduction measure, which is a useful frame for reading your own agreement. Where Visa imposes conditions on a member or its agent, the member must implement risk reduction measures that may include pledging collateral to secure obligations to Visa, consolidating settlement payments, and redirecting settlement funds to avoid potential losses — including, in Visa's own list, rerouting settlement funds around the financial institution that normally holds the funds, holding funds to ensure the correct application of cardholder funds, holding funds for the payment of merchants, holding funds for the future payment of disputes, and withholding funds for the purpose of obtaining collateral or meeting other member obligations. The same rule lets Visa require a member to provide data establishing, for a given period, the amount of funds a merchant has received from cardholders for goods and services it has yet to provide to them. Notice what is there and what is not. The mechanisms are named; no percentage, duration or threshold is. That is deliberate, and it is why nobody can honestly tell you what a normal reserve looks like. It also points at the right question when a hold appears: not what the industry standard is, but which of these mechanisms your provider is using, under which clause of your agreement, and against which exposure. Undelivered orders are singled out in the rules as the exposure worth measuring, so a business that takes payment well before delivery should expect that question and have the answer ready.
Depositing before you deliver is a rule, not a preference
One of the most common triggers for a funding review is also a rule breach, and merchants are rarely told so. Visa's Core Rules (Section 1.5.6.1, Table 1-10) say a merchant must not submit a deposit for a transaction until one of the following occurs: the transaction is completed; the merchandise or services are shipped or provided; or it has fulfilled the conditions of its agreement with the cardholder for an installment transaction, a recurring transaction or an unscheduled credential-on-file transaction. Billing a card the moment an order is taken, for goods that ship in six weeks, sits outside that, and it creates exactly the exposure the risk rules are written around: money collected for goods and services not yet provided. If deposits or pre-orders are genuinely part of your model — custom work, event bookings, build-to-order manufacturing — the answer is not to hide it. Tell the acquirer at application, describe the delivery timeline, and expect a reserve conversation. Use an advance-payment or installment arrangement your provider supports rather than capturing the full amount early, keep signed orders and delivery evidence, and refund promptly when an order falls through. A provider that knows your delivery lag can price for it; a provider that discovers it during a dispute spike will hold funds first and ask afterwards. This is general information, not legal advice (September 17, 2026).
Preventing the next one
Give accurate average and maximum ticket figures and monthly volume at application, and update them when your business changes. Warn your provider before a large order, a seasonal peak or a promotion. Keep refund and dispute rates low by describing products clearly and answering customers quickly. After a period of clean processing, ask whether a reserve can be reduced or released; put the request and the answer in writing. This is general information, not legal advice (September 17, 2026).
Key takeaways
- Visa's rules let acquirer payments be net of merchant reserve funds, but your agreement sets the amount and release
- Holds protect the provider against disputes and future-delivery risk it may have to cover
- Ask exactly which transactions are held and what documents will close the review
- Warn your provider before unusual sales, and update your declared ticket and volume figures
