The concept of a reserve on a merchant account can seem like a penalty to the merchant when the merchant is approved but does not receive the full amount. For high-risk merchants, though, this is part of the approval process for acquiring a merchant account.
Understanding the type of reserve and its reason is crucial to maintaining proper cash flow in the business. Rolling reserve merchant accounts work differently from merchant accounts that require an upfront reserve. Therefore, merchants should understand these terms to avoid problems with the merchant account and business finances.
Why Payment Processors Require Merchant Account Reserves
Processors require reserves when they believe the merchant may create future financial exposure for the processor. Such financial exposure can stem from a variety of reasons, including returned products, subscription cancellations, fraud, business closures, seasonal businesses, businesses with high sales volumes or ticket sales, or those with a limited processing history.
While a reserve is not always indicative of a safe merchant, it does mean the merchant will have the funds necessary should customers initiate chargebacks, refunds exceed the available balance, or the merchant fails to cover future financial obligations. For some high-risk merchants, the reserve is the difference between approval and decline.
Rolling Reserve vs. Upfront Reserve: What’s the Difference?
The reserve structure determines how much money is held, when it is held and when it may be released.
| Reserve Type | How It Works | Best Fit For | Cash-Flow Impact |
|---|---|---|---|
| Rolling Reserve | Processor holds a percentage of each batch, then releases it after a set period | High-risk merchants with ongoing sales volume | Predictable but reduces daily deposits |
| Upfront Reserve | Merchant funds a reserve before or near the start of processing | New accounts, high-ticket merchants or higher-risk models | Larger immediate cash requirement |
| Minimum Reserve | Processor holds funds until a required reserve balance is reached | Merchants with defined risk exposure | Deposits may improve after the minimum is reached |
| Capped Reserve | Reserve accumulates until a set cap is met | Seasonal or growing merchants with a measurable risk ceiling | Withholding may stop once the cap is reached |
| Jumpstart Reserve | Processor moves a fixed amount into reserve immediately | Merchants with sudden risk concerns or rapid growth | Can create an immediate working-capital squeeze |
| Delayed Funding | Processor slows settlement instead of holding a separate reserve percentage | Businesses with fulfillment or dispute timing concerns | Cash arrives later, but the structure may be simpler |
The most common high-risk structure is a rolling reserve. For example, a processor may hold 10% of each day’s card sales for 120 days, then release those funds on a rolling schedule if they are not needed for refunds or disputes.
Who Needs High-Risk Merchant Reserve Requirements
High-risk merchant reserve requirements are more common when a processor sees a higher chance of future liability.
They are especially common for:
- new merchants without processing history
- high-risk ecommerce businesses
- subscription and continuity merchants
- CBD, vape, nutraceutical, adult, travel, coaching and digital product merchants
- businesses with chargeback history
- merchants with large average tickets
- merchants selling future-delivery products or services
- seasonal businesses with volume spikes
- businesses recently shut down by Stripe, PayPal or Square
- merchants with high refund exposure
- startups scaling quickly after launch
A reserve may also appear after approval if the merchant’s volume, ticket size, dispute rate or product mix changes.
What Increases Merchant Account Reserve Requirements
Processors usually look at several risk signals before setting or increasing a reserve. The most common triggers are high chargeback ratios, refund spikes, rapid growth, large tickets, future delivery, long fulfillment windows, incomplete documentation, and unclear customer terms.
A reserve can also increase if the merchant begins processing activity not disclosed during underwriting. If the application described low-ticket retail but the business later processes high-ticket deposits, recurring subscriptions, or online orders in a restricted category, the processor may respond with a reserve, a payout delay, or an account review.
How Merchant Account Reserves Impact Cash Flow
While the reserve on a merchant account will impact the cost of using that account, it will also impact the timing of when the business receives its cash. If a business deposits $100,000 per month into its merchant account, but that account has a 10% reserve, $10,000 will be held from that month’s deposits and released back into the business in another month.
This may be fine under the right circumstances. However, if a business needs to use that money for another purpose, such as purchasing inventory or advertising to promote its products or services, this can create financial strain for the company. Thus, high-risk businesses should model any reserves that might be applied to their merchant account prior to signing the necessary forms to start accepting payments into that account.
How VAMP Impacts Merchant Account Reserve Requirements
Visa’s Visa Acquirer Monitoring Program (VAMP) is a combined program for monitoring fraud and disputes on the Visa network. The VAMP ratio is the number of fraud reports and non-fraud disputes divided by the number of settled Visa transactions. TC40 is the number of Visa fraud reports. TC15 is the number of Visa transactions that are disputed.
VAMP ratios affect the terms of merchant reserves. High VAMP ratios mean high potential liability for the merchant, so the terms of their reserves will typically be more restrictive.
The Visa Acquirer Monitoring Program (VAMP) also includes monitoring for enumeration attacks on merchants’ websites. Enumeration attacks use bots to test the security of a merchant’s website by attempting to enter various credit card numbers and expiry dates. The enumeration ratio for a merchant is the number of suspected enumeration attacks divided by the total number of authorization attempts on the merchant’s website.
For merchants with high-risk products or services, the goal of VAMP is to reduce the risk that would otherwise justify reserves in the merchant’s account. This can be accomplished with improved fraud filters and procedures for merchants to reduce chargebacks and alert them to potential issues with their shipments or customer communications.
How to Negotiate Better Merchant Account Reserve Terms
Reserve terms are not always permanent. If the merchant meets certain criteria, such as having a low return and refund rate, a high volume of orders fulfilled, and an overall great return policy, then the merchant may be able to negotiate a lower percentage, shorter period of time for which the transaction is held, a capped reserve amount, or even the date upon which the merchant will be reviewed for another potential step down in the percentage of the total transactions that are to be held as a reserve.
Documents Needed for Merchant Account Reserve Reviews
Documents to keep before asking for better terms from the merchant account company:
- processing statements
- chargebacks and refund records
- fulfillment records
- customer service records
- business bank statements
- supplier invoices and inventory records
- website terms and refund policy
- subscription terms
- fraud prevention tools used
- explanation of spikes in sales
- expected sales volume
- average ticket size
- maximum ticket size
- proof of low charge and refund activity
- updated business model description
These documents will make it easier for the account processor to underwrite the merchant’s business. The less likely the account processor is to require a higher sales volume from the merchant, the lower the reserve amount for the merchant’s account.
Common Merchant Account Reserve Mistakes to Avoid
The biggest mistake is looking at the rate alone to compare processors but ignoring the reserve terms. A low rate can mean expensive costs if 10%, 15%, or 20% of sales are unavailable for several months.
Another mistake is treating the reserve as random. Most of the time, there is some concern the processor has about the business. By lowering the chargebacks, documenting the fulfillment of orders, and presenting a solid explanation of how the business has improved, a company can get a better reserve terms in the future.
FAQs About Merchant Account Reserves
Q: What is a merchant account reserve?
A: A merchant account reserve is money held by a processor or acquiring bank to cover potential chargebacks, refunds, negative balances or other financial risk. The funds may be released later if they are not needed to cover losses.
Q: What is a rolling reserve merchant account?
A: A rolling reserve merchant account holds a percentage of each batch or transaction for a set period. After that period, funds are released on a rolling schedule if the merchant does not need them to cover disputes, refunds or fees.
Q: What is an upfront reserve?
A: An upfront reserve is a reserve funded before processing begins or near the start of the account. It may be required when the processor wants a fixed cushion before allowing the merchant to process larger or higher-risk payments.
Q: Why do high-risk merchants have reserve requirements?
A: High-risk merchant reserve requirements help processors manage potential losses from chargebacks, fraud, refunds, future delivery, high-ticket transactions or limited processing history. Reserves can make approval possible when the business would otherwise be declined.
Q: How much is a typical rolling reserve?
A: Rolling reserve terms vary by processor and risk profile. Some high-risk merchants may see reserves around 5% to 10% for 90 to 180 days, while higher-risk accounts may face stricter terms.
Q: Can merchant account reserves be reduced?
A: Sometimes. Merchants may be able to reduce reserves after showing several months of stable volume, low chargebacks, controlled refunds, clear fulfillment and stronger financial documentation.
Q: Are reserves the same as payment holds?
A: No. A reserve is usually a structured risk-control term, while a payment hold may be a temporary review or payout delay. Both affect cash flow, but they are not always the same thing.
Q: Can Payment Nerds help review reserve terms?
A: Payment Nerds can help eligible merchants compare merchant account reserve terms, rolling reserve merchant account options, high-risk merchant reserve requirements, chargeback controls and payment processor fit.
Conclusion
Merchant account reserves go beyond the payment processing detail. They impact the business’s cash flow and approval terms.
Payment Nerds can assist merchants by reviewing their merchant account reserve terms and comparing merchant account reserves on rolling terms and high-risk merchants’ reserve requirements. Our goal is to keep the merchants’ payments active while allowing them to create a merchant account with better terms in the future.
