These pre-authorisation holds can sometimes cause confusion, especially when customers see their available balance reduced without a final charge.

We’ve also explained how Wise Business can help you track pending transactions, improve visibility over held funds, and manage your business cash flow more effectively.

| What is a Pre-Authorisation? | A temporary hold placed by a merchant on a customer’s card, not a final payment. Funds are ring-fenced but not taken.1 |
| Why Businesses Use Them | To reduce the risk of non-payment, verify card validity, and ensure sufficient funds for variable costs.1 |
| Duration of Holds | Can range from a few hours to several days depending on the merchant and industry.2 |
A pre-authorisation is a temporary hold placed by a merchant on a customer's credit or debit card.1 The funds are not taken but are set aside, reducing the amount the customer can spend. This allows businesses to confirm funds are available before completing a transaction.3
From a business perspective, this also helps set expectations before delivering a product or service. Clearly communicating that a temporary hold will be placed—and how long it may last—can reduce confusion, support queries, and negative feedback from customers.
Businesses use pre-authorisation to reduce the risk of failed payments.1 It confirms that a card is valid and that sufficient funds or credit are available before delivering a service.
This is particularly useful where the final cost may change, such as hotels or car rentals.2 In these cases, pre-authorisation also gives businesses flexibility to adjust the final charge while maintaining payment security.
When a customer provides their card details, the merchant requests authorisation for a set amount from the issuing bank.3 If approved, the bank places a hold on that amount.
From the business’s perspective, this process acts as a safeguard:
Once the final amount is confirmed, the merchant captures the payment, and any unused portion of the hold is released.3
If the final charge is lower than the pre-authorised amount, only the actual cost is taken, and the remainder is returned to the customer.
If needed, the business may also adjust the amount before capture, depending on the payment provider and agreement terms.
To reduce customer confusion, businesses should clearly communicate expected hold amounts and typical release timeframes at checkout or during booking.
On a credit card, a pre-authorisation reduces the customer's available credit limit but does not result in a charge or interest.2
For businesses, this means the authorised amount is secured without immediately capturing funds, allowing you to confirm payment capability before delivering goods or services. It also reduces the risk of declined transactions at the point of final payment.
On a debit card, the held amount is unavailable to spend by the customer, reducing their available balance while the total balance remains unchanged.1
From a business perspective, this provides reassurance that the required funds are available in the customer’s account, but it can also lead to customer queries or friction if the held amount impacts their ability to spend elsewhere.
Being transparent about hold amounts and release timelines can help manage expectations and reduce complaints.
Hold durations vary by industry and provider. Some may last only hours, while others can remain for several days until the final payment is processed.2
For businesses, longer hold times can increase the likelihood of customer queries or dissatisfaction. Providing clear guidance on expected timeframes—either at checkout, in confirmation emails, or in FAQs—can help reduce support requests and negative reviews.
Pre-authorisations reduce the customer’s available balance, which may lead to declined transactions if not tracked carefully.2
From a business standpoint, this can create friction in the customer experience. Proactively explaining how holds work and when funds will be released can improve transparency and help maintain trust.
Hotels and rental companies often place holds to cover potential additional charges such as damages or extras.2
For businesses in these sectors, clearly communicating the hold amount and duration upfront is key to avoiding disputes and maintaining customer satisfaction.
Some services use small temporary holds to verify card validity when you sign up.4
While typically low in value, these can still trigger customer queries. Clear messaging during sign-up can help reduce confusion.
Retailers may place a hold when final pricing depends on weight or delivery adjustments.3
In these cases, setting expectations around pricing variability and temporary holds can help prevent misunderstandings and improve the overall customer experience.

A pre-authorisation holds funds temporarily, while a final charge transfers the money to the merchant.2
From a business perspective, the pre-authorisation secures the payment in advance, while the final charge completes the transaction.
Yes, due to insufficient funds, incorrect details, or fraud checks.6
For businesses, this highlights the importance of pre-authorisation in identifying potential payment issues before delivering goods or services.
The hold is released, and the merchant may need to request payment again.5
This can create operational friction, so businesses should aim to capture payments within the authorisation window where possible.
Pre-authorisations appear as pending transactions and reduce your available balance until completed or released.
For businesses, this provides visibility over incoming and outgoing holds, helping you better manage cash flow and reconcile transactions.
