How Do I Create My First Invoice as a UK Limited Company?

To create your first invoice as a UK limited company, give it a unique invoice number, identify your company and customer, describe what you supplied, state the relevant dates and show the total amount payable.

The invoice should be issued in the company’s full registered name—not only the director’s name or an informal trading name. If the company is VAT registered, additional information must be included and VAT must be calculated correctly.

A clear, professional invoice makes it easier for the customer to approve payment and provides an essential record for the company’s bookkeeping, annual accounts and tax returns.

What Is an Invoice?

An invoice is a formal document requesting payment for goods or services supplied by a business.

It normally records:

• Who supplied the goods or services
• Who the customer is
• What was supplied
• When it was supplied
• How much the customer must pay
• When payment is due
• How the customer should pay

An invoice is different from a quotation, purchase order or receipt.

• A quotation estimates the price before the work is accepted.
• A purchase order is normally issued by the customer to authorise a purchase.
• An invoice requests payment for a supply.
• A receipt confirms that payment has been received.

A pro forma invoice may be used to provide preliminary payment information, but it is not necessarily a final sales invoice or valid VAT invoice.

Can a New Company Issue an Invoice Immediately?

Yes. A limited company can generally issue an invoice as soon as Companies House has incorporated it and the company legally exists.

It does not normally have to wait for:

• Its Corporation Tax Unique Taxpayer Reference
• Its first annual accounts
• Its first confirmation statement
• An accountant to be appointed
• Its first Company Tax Return

The company should nevertheless have a suitable way to record the sale and receive payment.

If the activity requires a licence, regulatory approval or insurance, those requirements should be addressed before the company provides the relevant goods or services.

What Must a UK Company Invoice Include?

A standard invoice should contain the following information:

• A unique invoice number
• The company’s full registered name
• The company’s business or correspondence address
• Contact information
• The customer’s full name or business name
• The customer’s address
• A clear description of the goods or services
• The date the goods or services were supplied
• The date the invoice was issued
• The price of each item or service
• The total amount payable
• VAT details, where applicable

A limited company must show its full company name as it appears on its certificate of incorporation.

It is also good practice to show:

• The company registration number
• The registered office address
• The part of the UK in which the company is registered
• The company’s payment details
• The payment deadline
• The customer’s purchase-order number
• A contact for payment queries
• The currency of the invoice

Including this information helps customers confirm the identity of the legal entity they are paying.

Should I Use the Registered Company Name or Trading Name?

The invoice should clearly identify the registered limited company.

If the company trades under a different business name, it can show both names. For example:

Northstar Digital is a trading name of Northstar Ventures Limited.

The registered company name should appear in full, including “Limited” or “Ltd”.

Do not issue the invoice solely in the name of a brand if the customer cannot identify the company behind it. This can cause payment delays, contract disputes and compliance problems.

The name on the invoice should also be consistent with the name on the company’s business bank account and customer contract.

Does the Invoice Need the Company Registration Number?

The company registration number is useful and should normally be included, even where the invoice-specific rule focuses on displaying the company’s full registered name.

Including the registration number helps customers distinguish the company from businesses with similar names. It may also be requested during:

• Supplier onboarding
• Business account verification
• Payment approval
• Compliance checks
• Credit applications
• Cross-border transactions

Use the number exactly as it appears on the certificate of incorporation and Companies House record.

The company registration number is not the same as the Corporation Tax UTR or VAT number.

Does the Invoice Need the Registered Office Address?

Including the registered office address is good practice, particularly where the company uses another address for everyday correspondence.

The invoice may show:

• The registered office address
• A separate business or correspondence address
• A separate return address for goods

Each address should be clearly labelled so the customer knows which one to use.

The registered office does not have to be the address from which the company actually operates, but it must remain an appropriate address for receiving official company correspondence.

How Should I Number My First Invoice?

Every invoice should have a unique identifying number.

Your first invoice might be:

• 001
• INV-001
• 2026-001
• UK-2026-001

The numbering system should be consistent and easy to follow.

A growing company could use a format such as:

INV-2026-0001

The next invoices would then be:

INV-2026-0002
INV-2026-0003
INV-2026-0004

Do not give two invoices the same number. If the company has several sales channels or business divisions, it can use separate invoice-number sequences, provided each sequence remains unique, organised and traceable.

Avoid including sensitive personal information in the invoice number.

Can I Start With Invoice Number 001?

Yes. A new company can start with invoice number 001.

There is no need to make the first invoice appear larger or more established by starting with an artificial number. The important point is that the numbering system is unique and sequential.

Where accounting software generates invoice numbers automatically, check the starting number and format before issuing the first invoice.

What Dates Should Appear on the Invoice?

A standard invoice should normally show:

Invoice date

This is the date on which the invoice is issued.

Supply date

This is the date on which the goods were delivered or the services were provided. It may be described as the service date, delivery date or tax point.

The invoice date and supply date may be the same, but they are not always identical.

For a service performed throughout a month, the invoice could state:

Services provided from 1 August 2026 to 31 August 2026.

For goods, it could state:

Goods delivered on 30 August 2026.

If the company is VAT registered, identifying the correct tax point is particularly important because it can determine the VAT period in which the sale must be reported.

Payment due date

The due date tells the customer when payment must arrive.

For example:

Payment due by 30 September 2026.

A specific date is often clearer than wording such as “Net 30”, particularly when dealing with international customers who may interpret payment terms differently.

What Description Should Be Included?

The description should be detailed enough for the customer to understand and approve the charge.

A vague description such as “services” may cause delays. A clearer description might be:

Website design and development services completed during August 2026, in accordance with proposal reference WD-104.

For products, include relevant details such as:

• Product name
• Quantity
• Unit price
• Model or reference number
• Delivery charges
• Discounts
• Purchase-order reference

For recurring services, identify the billing period.

If the customer uses an internal purchase-order system, include the correct purchase-order number. Some organisations will not process an invoice without it.

How Do I Calculate the Invoice Total?

The invoice should show how the total was calculated.

Depending on the transaction, include:

• Quantity
• Unit price
• Hours worked
• Hourly or daily rate
• Subtotal
• Discount
• Delivery charge
• VAT
• Amount already paid
• Final balance due

For example:

Consulting services: 10 hours at £75 per hour — £750
Subtotal — £750
VAT — Not applicable
Total payable — £750

Check the arithmetic before sending the invoice. Small calculation errors can delay payment and make the bookkeeping records inaccurate.

What Payment Details Should Be Included?

Give the customer clear instructions for paying the company.

For a UK bank transfer, this may include:

• Account holder name
• Sort code
• Account number
• Payment reference

For an international payment, it may include:

• Account holder name
• IBAN
• SWIFT or BIC
• Bank address, if requested
• Payment currency
• Payment reference
• Instructions about transfer fees

The account holder name should normally match the company’s registered name.

If the company uses a payment link or online payment facility, make sure the link is secure and belongs to the company’s authorised provider.

Bank details should be checked carefully before issuing the invoice. Invoice fraud commonly involves criminals changing payment instructions. Customers should be told to verify unexpected changes through a trusted contact method.

Can a Company Invoice Before Opening a Business Bank Account?

A company can generally create an invoice before its business bank account is fully operational. It may set a payment due date that gives enough time to complete the account opening.

However, the company should avoid routinely directing customer payments into a director’s personal account. A limited company is a separate legal entity, and its finances should be kept separate from those of its owners.

If no account is available, the company may:

• Wait before issuing the final invoice
• Agree a later payment date
• Use an authorised business payment facility
• State that payment instructions will follow securely

Do not add unverified or temporary third-party payment details simply to issue the invoice quickly.

What Payment Terms Should I Use?

Payment terms should be agreed before or when the customer places the order—not introduced unexpectedly after the work is completed.

Common terms include:

• Payment in advance
• Payment on delivery
• Payment on receipt
• Payment within 7 days
• Payment within 14 days
• Payment within 30 days
• Payment by a specific date
• Instalment payments
• A deposit followed by a final balance

The best terms depend on:

• The value of the sale
• The customer’s creditworthiness
• The company’s cash-flow needs
• Industry practice
• The length of the project
• Whether goods must be purchased in advance
• Whether the customer is in another country

New companies may reduce payment risk by requesting a deposit or payment in advance for significant work.

The invoice should reflect the terms already agreed in the contract, order form or accepted quotation.

Should Late-Payment Terms Be Included?

The invoice can state what may happen if payment is late.

For example:

The company reserves the right to charge interest and recover applicable costs on overdue commercial debts in accordance with the contract and relevant legislation.

The right to charge interest may arise from the contract or UK late-payment legislation in qualifying business-to-business transactions.

The company should not add arbitrary penalties that were never agreed or are legally unenforceable. Late-payment wording should be consistent with the customer contract and applicable law.

Does a Non-VAT-Registered Company Add VAT?

No. A company that is not registered for VAT must not charge VAT.

Its invoice can state:

Not registered for VAT.

This is optional, but it can prevent customers from asking for a VAT invoice.

A non-VAT-registered company should not:

• Add a VAT percentage
• Describe part of the price as VAT
• Use another business’s VAT number
• Suggest that the customer can reclaim VAT

The company should monitor its taxable turnover and register when required. Once registered, it will need to follow the applicable rules about when it begins charging VAT.

What Must a VAT Invoice Include?

A VAT-registered company must include additional information on a full VAT invoice.

This normally includes:

• A unique sequential invoice number
• The invoice date
• The time of supply or tax point
• The supplier’s name and address
• The supplier’s VAT registration number
• The customer’s name and address
• A description sufficient to identify the goods or services
• The quantity or extent of the supply
• The unit price, where applicable
• The net amount excluding VAT
• The VAT rate applied
• The VAT amount
• The gross total including VAT
• Any legally required VAT wording

Different rules may apply to simplified VAT invoices, modified VAT invoices, margin schemes, self-billing and particular international transactions.

The company should ensure that the VAT number belongs to the invoicing company and is entered correctly.

What Is a Simplified VAT Invoice?

A simplified VAT invoice may generally be used for lower-value supplies where the total amount, including VAT, does not exceed the applicable limit.

It normally requires less information than a full VAT invoice but must still contain prescribed details, such as:

• A unique identifying number
• The supplier’s name, address and VAT number
• The time of supply
• A description of the goods or services
• The total amount including VAT
• The VAT rate

A full VAT invoice may still be more appropriate for a business customer that wants to reclaim VAT.

Can I Invoice in EUR, USD or Another Currency?

Yes. A UK company can invoice in a foreign currency.

The invoice should clearly state:

• The invoicing currency
• The amount payable
• The account into which payment should be made
• Who bears bank and intermediary charges
• Any agreed exchange-rate mechanism
• Whether conversion is permitted

A company can issue separate invoices in currencies such as GBP, EUR or USD and receive the funds into corresponding business currency accounts.

This can make payment easier for overseas customers and reduce unnecessary currency conversions.

The bookkeeping records must still translate the transaction into the company’s accounting currency using an appropriate exchange rate. Exchange differences may arise between the invoice date and payment date.

If UK VAT is charged, the required VAT figures must be presented according to the relevant sterling-conversion rules, even where the commercial invoice is denominated in another currency.

How Do I Invoice an Overseas Customer?

An overseas invoice should include all the normal information, together with clear international payment instructions.

Before applying VAT, establish:

• What is being supplied
• Whether the customer is a business or consumer
• Where the customer belongs
• Where the supply takes place for VAT purposes
• Whether the customer has a valid tax registration number
• Whether reverse-charge wording is required
• Whether the transaction is zero-rated, outside the scope or taxable
• Whether another country’s registration rules apply

Do not assume every overseas sale is automatically VAT-free.

International VAT and sales-tax rules vary depending on the nature of the supply and destination. Professional advice may be appropriate where the treatment is uncertain.

Should I Add the Customer’s VAT Number?

The customer’s VAT number may be required or useful for certain transactions, particularly cross-border business-to-business supplies.

Where it is relevant:

• Obtain the number before invoicing
• Check that it belongs to the customer
• Retain evidence of any validation
• Enter it accurately on the invoice
• Keep supporting evidence of the customer’s business status

A VAT number should not be treated as the only evidence when the applicable rules require additional proof.

Can I Create an Invoice in a Spreadsheet or Document?

Yes. A non-VAT-registered company can create invoices using a spreadsheet, document template or invoicing system, provided the invoice contains the necessary information and the records are maintained properly.

However, accounting software can provide useful controls such as:

• Automatic invoice numbering
• Customer records
• Payment reminders
• Bank matching
• VAT calculations
• Credit notes
• Currency conversion
• Accounts receivable reports
• Digital record retention

VAT-registered companies must ensure that their records and VAT reporting comply with Making Tax Digital requirements.

Regardless of the method used, save a final copy of every invoice exactly as sent to the customer.

Can I Send an Invoice by Email?

Yes. Invoices are commonly sent as PDF files by email or through an online invoicing system.

Before sending, confirm:

• The recipient’s email address
• The customer’s legal name
• The purchase-order number
• The invoice amount
• The payment due date
• The bank details
• The attachment
• The email subject line

A useful subject line is:

Invoice INV-2026-0001 from Example Trading Ltd

The email can briefly state:

Please find attached invoice INV-2026-0001 for services completed in August 2026. Payment of £750 is due by 30 September 2026 using the payment details shown on the invoice.

Do not include sensitive authentication information in the email.

How Should Deposits Be Invoiced?

If the customer must pay a deposit, the company can issue a deposit invoice stating:

• The total project or order value
• The deposit amount
• The due date
• What the deposit secures
• Whether it is refundable
• When the balance will be invoiced

For example:

Deposit of 30% payable before work begins. The remaining 70% will be invoiced when the project is completed.

VAT-registered companies should check whether receipt of the deposit creates a tax point and affects when VAT must be accounted for.

The final invoice should clearly show the full charge, deposit already invoiced or paid, and remaining balance.

How Do I Correct an Invoice?

Do not delete or secretly overwrite an invoice that has already been sent.

If the invoice contains an error, the appropriate process may be to:

1. Issue a credit note cancelling all or part of the original invoice.
2. Create a corrected invoice with a new unique number.
3. Link both documents to the original transaction.
4. send the documents to the customer.
5. Update the bookkeeping and VAT records.

Minor administrative information may sometimes be corrected using a clearly documented replacement, but the audit trail should remain intact.

If an invoice has not yet been sent, it can usually be corrected before issue while retaining proper control of the numbering sequence.

What If an Invoice Number Is Skipped?

A skipped number does not automatically invalidate the invoice sequence, but the reason for the gap should be documented.

For example, the company may record:

INV-2026-0007 voided before issue because it was created in error.

Do not reuse the number for another customer if doing so could create confusion.

Accounting software will often preserve deleted or voided invoice numbers automatically.

When Should an Invoice Be Recorded in the Bookkeeping?

Record the invoice when it is issued or when the accounting and tax rules require the sale to be recognised.

The bookkeeping system should show:

• Sales income
• VAT liability, where applicable
• The amount owed by the customer
• The payment when received
• Payment-processing fees
• Exchange gains or losses
• Credit notes or refunds

Do not record only the bank deposit. If fees have been deducted before settlement, record the gross invoice amount and the fees separately.

For example, if the invoice is £1,000 and the payment provider deducts £20, the bookkeeping should normally show:

• £1,000 of customer payment
• £20 of processing fees
• £980 received into the bank

How Long Should Invoice Records Be Kept?

A limited company should generally retain its accounting records for six years from the end of the financial year to which they relate.

Records may need to be kept for longer where:

• A transaction covers more than one accounting period
• The company filed a tax return late
• HMRC has opened a compliance check
• The record relates to a long-term asset
• Another legal or contractual requirement applies

Keep copies of:

• Issued invoices
• Credit notes
• Customer contracts
• Purchase orders
• Delivery evidence
• Payment confirmations
• Foreign-exchange calculations
• Correspondence about disputes or adjustments

Digital copies should remain readable, secure and accessible.

Frequently Asked Questions

Can my first invoice be number 001?

Yes. Your first invoice can be 001, provided that later invoices follow a clear and unique sequence.

Must a UK company use accounting software to create invoices?

Not necessarily. A company can create an invoice using a document or spreadsheet, but suitable accounting software provides stronger numbering, bookkeeping and payment controls.

Does the director’s name need to appear?

Not normally. If the company chooses to include directors’ names, it should generally include the names of all directors rather than selecting only one.

Can I invoice under my website or brand name?

You can show the brand, but the invoice must clearly identify the full registered limited company behind it.

Can I send an invoice before completing the work?

Yes, if the contract requires advance payment, a deposit or staged billing. The invoice should clearly explain what the payment covers.

Can I send an invoice without a UTR?

Yes. The Corporation Tax UTR does not normally appear on customer invoices and should generally be kept secure.

Should the UTR appear on an invoice?

No. A company’s UTR is used for tax administration and is not normally included on sales invoices.

Can I include an IBAN on a UK invoice?

Yes. An IBAN and SWIFT or BIC may be useful where the customer will pay internationally.

Can a customer pay an invoice in another currency?

Yes, if the company agrees. The exchange method, payment currency and responsibility for charges should be clear.

Is a PDF invoice valid?

Yes. An invoice can generally be issued electronically. A VAT invoice sent electronically must contain the same required information as a paper VAT invoice.

What if the customer pays only part of the invoice?

Record the partial payment against the invoice and leave the remaining amount outstanding. Do not create a replacement invoice simply because only part has been paid.

Should I mark an invoice as paid?

The bookkeeping system should record when payment is received. A paid copy or receipt can be sent to the customer if requested.

Final Answer

To create your first invoice as a UK limited company, use the company’s full registered name, assign a unique invoice number and include the customer’s details, invoice date, supply date, clear description, amount payable and payment deadline.

Add accurate business payment instructions and make the invoice currency clear. If the company is VAT registered, include its VAT number, VAT rates, net values and VAT amounts in accordance with the applicable rules.

Save an exact copy of the invoice, record it in the bookkeeping system and preserve the numbering sequence. A clear first invoice establishes the process the company can use for all future sales.
