Direct Debits are a simple, secure, and convenient way for businesses to take regular payments directly from their customers’ bank accounts in exchange for a product or service. 

Once a Direct Debit has been agreed, you are authorized to take a certain amount on a particular date without any further action from the customer, unless you need to change the date or amount taken. 

This saves your customer time, and helps you strategize effectively by giving you a steady and predictable cash flow. 

But without a Direct Debit mandate, the agreement that authorizes you to deduct payments from their account, there can be no Direct Debit. 

In this article, we explain what a Direct Debit mandate is, how they work, and how you can set them up. 

What is a Direct Debit mandate?

A Direct Debit mandate (DDM) – known as a Direct Debit instruction (DDI) in the UK – is when a customer authorizes you to collect future payments from their account on a predetermined schedule. You must notify your customer of the upcoming payment each time you take it.

With the mandate in place, your business is authorized to collect payments of any amount and at any time from your customer, with advanced notice.

In the UK, these payments are covered by the Direct Debit Guarantee. This means in the event that an incorrect or fraudulent payment is taken, the customer is entitled to a full and immediate refund.

How do Direct Debit mandates work?

To set up a Direct Debit mandate, your customer needs to complete a mandate form, which requires them to provide their banking details. This form can be completed in three ways: online, over the phone, or by completing a paper application form. 

Once you’ve received all the necessary payment information from your customer, you must submit it to the banks before you can collect future payments. Your PSP will be able to help you with this.

This submission must be conducted through a clearing service, which facilitates the electronic transfer of funds between bank accounts. Which clearing service you use depends on the country you operate in. 

US: ACH debit authorization

ACH (Automated Clearing House) is the computer-based network that enables electronic funds transfers in the US. To collect ACH Direct Debits, you must have a US-registered business entity. 

You can present an ACH debit authorization to your customer at checkout. This agreement must comply with National Automated Clearing House Association (NACHA) rules, and clearly set out the terms of the transaction (or recurring transactions).

Once approved, ACH Direct Debit payments can be taken and the funds should appear in your account within 2-4 working days. 

You can accept ACH Direct Debits with Flow, the payment interface you can customize with clicks, not code.

UK: Bacs Direct Debit mandate

Bacs Payment Schemes Limited (originally known as Bankers’ Automated Clearing System) is responsible for clearing and settling bank-to-bank transfers in the UK. If you have a UK entity, you can use Bacs Direct Debit payment scheme to collect recurring or one-off payments from a UK bank account. You'll need to onboard with Bacs, but we can help you do this.

Checkout.com will create the Direct Debit Instruction (DDI) on your behalf – see our documentation on setting up the DDI for more detail. There is a waiting period of roughly five days before you can collect payment.

Once the DDI is set up, you can change the amount or the frequency, though you must let the customer know in advance. Either you or your customer can cancel the Direct Debit by submitting a cancellation message to their bank.  

Europe: SEPA Direct Debit mandate

Single Euro Payments Area (SEPA) facilitates electronic credit or debit transfers between countries in the EU and a number of other non-EU countries (including the UK). Businesses whose customers use Euro-denominated bank accounts need to submit SEPA-compliant mandate forms

SEPA Direct Debit mandate forms can be completed by your customer online, over the phone, or by filling in a paper form. These mandates must include mandatory legal text and additional information about the merchant, the customer, and the nature of the payment. These are then submitted to the banks and should be stored as future evidence of the authorization. The wording for B2B and B2C SEPA Direct Debit mandates varies. 

The SEPA Direct Debit scheme also permits e-mandates, which are completed through the customer’s online banking when they attempt a payment on your website. However, there are not currently very few e-mandate services available. 

What Does A Direct Debit Mandate Contain?

The text and required information for Direct Debit mandates vary depending on your jurisdiction. Generally speaking, however, they should include the following:

  • Banking details for your customer:
  • Name of the account holder
  • Account number
  • Branch sort code
  • Name and full postal address of the bank
  • A payment reference
  • Your or your payment provider’s Service User Number (SUN), a unique six-digit number that identifies any business collecting Direct Debits
  • The date of instruction
  • Wording for the Instruction to the bank from the account holder authorizing the setup, which could look something like this in the UK:
    “Please pay [your company’s name] Direct Debits from the account detailed in this Instruction subject to the safeguards assured by the Direct Debit Guarantee…” 

Many payment service providers provide support for Direct Debit mandates, including templates and the option to submit mandates to the relevant system or authority on your behalf. 

What are the benefits of Direct Debit mandates?

Here are the key benefits of Direct Debit mandates:

  • Recurring revenue is great for cash flow – you control the frequency and value collected, providing predictable funds
  • Lower cost than credit or debit card payments – account-to-account payments have lower payment processing costs
  • Combats fraud risk – payments come from verified customers
  • Fewer chargebacks – the customer is less likely to initiate a chargeback. Instead, they may cancel their Direct Debit mandate if desired

What is the difference between a standing order and a Direct Debit mandate?

Direct Debit mandates and Standing Orders are both automatic methods of taking payments directly from a bank account but differ in who initiates the payment.

Firstly, a Direct Debit is initiated by the business, which needs the customer’s approval for future payments. A Standing Order is initiated by the customer and set up through their bank. 

Secondly, the business can make changes to the date, amount, or frequency of a Direct Debit but must inform the customer in advance. In contrast, you have no control over a Standing Order - only the customer can amend the payment terms.

Finally, while Direct Debits are protected by the Direct Debit Guarantee, Standing Orders have no such protection. If a payment is taken by mistake or there is an error, the customer must work it out with you or their bank directly.
