A high-risk merchant account can be approved but comes with limits. The processor may approve the merchant but require a rolling reserve, limiting the number of payments the merchant can receive or capping the volume they can process each month.
A reserve, hold, or cap on a merchant account can impact the business’s payroll, inventory, advertising, and customer service departments. It is essential to understand these limits before the merchant account is approved.
Why Payment Processors Use Reserves, Holds & Account Caps
Processors use reserves, holds, and caps to manage the risks that lie ahead for merchants. Should customers dispute charges, process refunds, increase fraud, or the merchant find themselves unable to fulfill orders, the processor and acquiring bank will need to have funds available to cover those losses for the merchant.
Rolling Reserves vs. Processing Holds vs. Account Caps
These terms are often grouped together, but they work differently.
| Control | How It Works | Why It Happens | Cash-Flow Impact |
|---|---|---|---|
| Rolling Reserve | Processor holds a percentage of each batch and releases it after a set period | Chargebacks, refunds, high-risk industry or limited history | Predictable holdback from ongoing sales |
| Upfront Reserve | Merchant funds a reserve before or near account approval | Higher-risk account, large tickets or new merchant history | Immediate cash requirement |
| Minimum Reserve | Processor holds funds until a required reserve balance is reached | Processor wants a fixed protection amount | Deposits may improve after the target is met |
| Processing Hold | Processor delays or freezes funds during review | Unusual activity, verification issue, chargebacks or risk concern | Sudden payout disruption |
| Account Cap | Processor limits monthly volume, ticket size or transaction count | Merchant was approved for a specific risk profile | Growth may be blocked until the cap is raised |
| Delayed Funding | Processor slows settlement by several days | Refund, fulfillment or chargeback exposure | Cash arrives later than expected |
A rolling reserve merchant account is often easier to plan around than a sudden hold. The merchant knows a percentage will be withheld and can model cash flow around the release schedule.
How Rolling Reserves Affect Business Cash Flow
A rolling reserve affects the number of deposits a merchant makes per day or per batch. For example, if 10% of a merchant’s sales is rolled for 120 days, then they will receive 90% of sales as they are made, with the remaining 10% rolled up and deposited into the merchant’s account after those sales are made.
The problem with rolling reserves is not necessarily the reserve. The problem is the failure to plan for the rolling reserve. High-risk merchants should plan for rolling reserves before they sign an agreement with a payment processor to determine whether they can still cover their expenses.
Why Payment Processing Holds Happen
A processing hold differs from a reserve in that it can occur suddenly. A processor may place a hold on a merchant’s account after a chargeback spike, a high volume of transactions, high-ticket sales, verification of the merchant, a change in the products being sold, or a refund and customer complaint.
If a hold happens, the merchant should have the documentation together to prove the charges and the reasons for the hold on the merchant’s processing account. Statements and sales receipts, order tags, proof of shipment, refund records, customer service records, business documents, and bank account statements, along with a reason for the changes to those accounts, can be gathered.
How Merchant Account Caps Limit Business Growth
An account cap limits how much of a given resource a merchant can process. The caps can be placed on monthly volume, ticket size, batch size, and transaction count.
Payment processors often use caps to gradually approve new merchants based on transaction volume. New merchants will start with a low transaction volume and prove themselves before requesting a higher transaction limit.
What High-Risk Merchants Should Negotiate
While many reserves, holds, and caps are permanent, a merchant can sometimes negotiate better terms after several months of clean processing.
Commonly negotiated terms include:
- percentage of sales to reserve
- length of time to hold those reserves
- cap on the amount of sales to reserve
- date to review the high-risk merchant account
- schedule for steps to reduce the high-risk merchant account
- maximum ticket size to process
- monthly processing cap
- timing of payouts
- documentation required to release reserved funds
- conditions that result in higher sales reserves
- actions to take after a chargeback spike
- whether ACH can reduce the high-risk merchant account pressure
Even though a high-risk merchant account may have certain controls imposed on it, the merchant should know what must happen for those terms to be improved.
How Visa VAMP Impacts Rolling Reserves & Processing Holds
The Visa Acquirer Monitoring Program (VAMP) is a program that Visa uses to monitor its transactions for fraud and disputes. The VAMP ratio is the number of fraud and non-fraud disputes divided by the number of settled Visa transactions. Visa’s TC40 record is its fraud report rate, while its TC15 is the number of Visa transactions that are disputed or subject to chargebacks.
VAMP is important for merchants assessing their reserves and holds because these three categories are often correlated with the reasons for fraud and disputes. If a merchant has high levels of fraud and disputes, their processor may require higher reserves or impose other funding terms on that merchant.
VAMP also includes monitoring for enumeration attacks. Enumeration attacks are often carried out by bots that test Visa cards at a merchant’s checkout or payment page. The enumeration ratio for a merchant is the number of suspected enumeration attacks for that merchant divided by the total number of authorization attempts.
For merchants at high risk of fraudulent or chargeback transactions, VAMP allows them to monitor their levels of fraud, disputes, chargebacks, and other issues that could lead to holds or reserves being placed on them. By monitoring these metrics themselves, merchants can address issues before their processor makes the same determination.
Common Rolling Reserve & Processing Hold Mistakes to Avoid
The biggest mistake is focusing only on processing rates. A low processing rate can still mean high costs if the merchant account has a high reserve or cap, or if its payout holds.
Another mistake is hiding the expected transaction volume. If a company has a product launch or season promotion, the processor should be aware of this before the sales begin.
FAQs About Rolling Reserves and Account Holds
Q: What is a rolling reserve merchant account?
A: A rolling reserve merchant account will hold a percentage of each batch or transaction for a set period of time. The money will be released later on a schedule if it is not needed for any disputes, refunds, or fees associated with those transactions.
Q: What is a rolling reserve?
A: A rolling reserve is a sum of money that is held from the sales of a merchant to protect the merchant account processor in the case of future financial risk from that merchant. It is typically given to high-risk merchants or those who are new to the merchant account space.
Q: What is a merchant account reserve?
A: A merchant account reserve is the amount of money held by the merchant account processor or bank to counter potential chargebacks, negative balances, or other forms of loss from the merchant account.
Q: Why do high-risk merchants get reserves?
A: High-risk merchants get reserves because the merchant account processor will experience higher potential risks and losses from those merchants due to the nature of their business.
Q: Is a rolling reserve the same as a processing hold?
A: No. A rolling reserve is typically a feature of the merchant account and the merchant has to live with the reserve. A processing hold may be placed during a merchant review and is temporary.
Q: What is an account cap?
A: An account cap is a limit placed by the merchant account processor on the volume, ticket size, or the number of transactions that can be processed by the merchant each period. The caps are set to ensure the merchant’s activities fall within the agreed upon risk level of the merchant account processor.
Q: Can reserves be reduced over time?
A: In some cases, merchant reserves can be reduced by the merchant account processor if the merchant accounts meets certain requirements or exhibits certain behaviors over time.
Q: Can Payment Nerds help review merchant account reserves?
A: Payment Nerds can assist merchants with qualifying merchant account applications with a review and comparison of rolling reserve merchant account options, rolling reserve terms, merchant account reserve requirements, and high risk merchant account structures.
Conclusion
Rolling reserves, processing holds and account caps aren’t a small detail in high risk payment processing. They define the money available to the business in practice as it develops.
Payment Nerds can assist qualified merchants with rolling reserve merchant account rules, merchant account reserve requirements, processing holds, account caps and high risk merchant account alternatives to avoid losing out on processing yet also to avoid unforeseen funding limits.
