Introduction to Self-Billing
Keeping on top of invoicing can be a challenge for many businesses. Between chasing payments, raising invoices, and matching paperwork, it can take up a lot of valuable time. This is where self-billing can offer a practical solution. Self-billing is an arrangement that allows a customer to create and issue invoices on behalf of their supplier, making the entire process simpler and more efficient for both parties.
Self-billing is commonly used in industries where there are regular, repeat transactions or where the customer needs to maintain tight control over purchasing and payments. It can save time, reduce admin, and improve cash flow management for businesses of all sizes.
How Does Self-Billing Work?
Under a self-billing arrangement, instead of the supplier issuing their own invoice for payment, the customer generates the invoice and sends it to both themselves and the supplier. The invoice includes all the usual details that a VAT invoice would require, such as the supplier’s name, address, VAT registration number, and a clear breakdown of the goods or services provided.

Once issued, the customer processes the payment based on the self-billed invoice. The supplier does not raise their own invoice for the same transaction. This method is especially useful where the buyer has a good system for tracking goods or services received and wants to simplify the paperwork involved.
What Is a Self-Billing Agreement?
A self-billing agreement is a formal, legally binding document signed by both the customer and the supplier. It outlines the terms of the self-billing arrangement and ensures that both parties are clear about their responsibilities.
The agreement must include:
- A statement from the supplier confirming they agree to the customer issuing invoices on their behalf
- A confirmation that the supplier will not issue their own VAT invoices for the same transactions
- The duration of the agreement and the process for renewal
- A requirement for the supplier to notify the customer of any changes to their VAT registration
- Details of any third party involved if invoicing is outsourced
Having a proper self-billing agreement in place is vital for legal compliance and for ensuring that the VAT treatment of transactions is correct.
Benefits of Self-Billing
Saves Time and Reduces Admin
One of the biggest advantages of self-billing is the time it saves. Suppliers no longer need to spend time preparing and sending invoices, and customers can standardise their internal processes by generating invoices themselves. This can lead to quicker payments and fewer delays caused by invoice errors or disputes.
Improves Cash Flow Management
Because the customer controls when the invoice is raised and when payment is made, it becomes easier to manage cash flow. Businesses can schedule payments according to agreed terms, knowing that there are no missing invoices or waiting periods.
Reduces Errors in Invoicing
Self-billing helps reduce invoicing mistakes because the customer is creating the invoice based on their own records. This leads to fewer disputes about quantities, prices, or payment terms. Having consistent, accurate invoices also makes reconciliation and auditing much easier.
VAT and Self-Billing Explained
For VAT-registered businesses, getting the VAT element of self-billing right is critical. A self-billed invoice must meet all the usual requirements of a VAT invoice, including:
- The supplier’s VAT registration number
- A description of the goods or services
- The amount excluding VAT
- The VAT rate applied
- The total including VAT
An important point to remember is that if the supplier is not VAT registered, no VAT should be charged on the self-billed invoice. Even if the customer is VAT registered, the VAT treatment must reflect the supplier’s VAT status, not the customer’s.
Additionally, every self-billed invoice should include a statement such as “The VAT shown is your output tax due to HMRC.”
Who Can Use Self-Billing?
Self-billing can be used by any business that agrees terms with its suppliers. It is often found in industries like construction, logistics, marketing, and temporary staffing, where suppliers provide services on a regular basis.
However, it is important that both the customer and the supplier understand and agree to the arrangement. The supplier must consent to the customer issuing invoices on their behalf, and this consent must be formalised in a signed agreement.
Common Mistakes with Self-Billing
Not Having a Proper Agreement
Failing to put a proper self-billing agreement in place can lead to serious problems. Without a signed agreement, the self-billed invoices may not be valid for VAT purposes, and disputes could arise between the customer and supplier over payments.

Always ensure there is a written agreement that covers all the necessary legal requirements before starting a self-billing arrangement.
Incorrect VAT Treatment
Another common mistake is applying VAT incorrectly. Customers must remember that the VAT treatment is based on the supplier’s VAT status. Charging VAT when a supplier is not VAT registered, or failing to charge it when they are, can lead to compliance issues and penalties from HMRC.
Failing to Update Agreements Annually
Self-billing agreements should be reviewed and renewed at least every 12 months. Circumstances change, and suppliers may update their VAT status or business details. An outdated agreement could result in incorrect invoicing and VAT errors.
How to Set Up Self-Billing
Setting up self-billing involves a few simple steps:
- Discuss the arrangement with your supplier and gain their agreement.
- Draft a self-billing agreement that covers all necessary details.
- Have both parties sign the agreement and keep a copy for your records.
- Create and issue self-billed invoices for all transactions covered by the agreement.
- Review and renew the agreement at least once a year.
Good record-keeping is essential. Keep copies of all invoices and agreements as part of your business’s accounting records to ensure VAT compliance and make year-end processes smoother.
Conclusion: Is Self-Billing Right for You?
Self-billing is a practical invoicing solution that can save time, reduce admin, and streamline your financial processes. While it is not suitable for every business, it offers significant advantages for those with regular suppliers and a desire to maintain tight control over their accounting.
By setting up proper agreements, ensuring VAT compliance, and reviewing arrangements regularly, businesses can enjoy the many benefits of self-billing without unnecessary risk. If you are unsure whether self-billing is the right choice for you, speaking to a professional accountant can help you make the best decision for your business needs.
