This guide explains how to structure VAT and GST invoices, highlighting key sections, mandatory fields to include, optional elements, and best practices for showcasing your brand while meeting legal standards. It stresses the need to comply with different regional tax rules, which can affect how the invoice looks and what information is required. This guide is provided for informational purposes only and offers a general overview of common B2B invoicing requirements. It does not constitute legal, tax, or accounting advice and should not be relied upon in place of professional consultation. Requirements and tax names vary significantly by jurisdiction and change frequently. This information is subject to review and verification by qualified legal and tax experts in each relevant country before implementation. We based the country groupings on common patterns for typical digital goods B2B transactions. Still, they may not capture all specific nuances or exceptions regarding field format, conditional requirements (like reverse charge text), or mandatory e-invoicing data points. # Layout options The following image shows an example of a layout option. This topic is not a layout guide; the layout may differ if you include all required items. The design must include all required fields and ensure that it reflects your brand identity, making it easier for you and your customers to process information.

# Sections This topic outlines each invoice section's required and optional fields and data sources. For an example of an invoice's layout, see the [Layout option](#layout-options).

This label (e.g., VAT ID, GSTIN) varies by country and is required where tax identification is mandated. You can translate the field labels when appropriate.

The actual business ID or tax ID number is necessary for jurisdictions that require tax identification on invoices. | | | `Customer_Tax_ID_Label_2` | \[Varies per country, when present] | Required in select countries | Include the customer's second tax ID label.

The section includes the following field identifiers: {`

Field Identifiers	Field Contents	Presentation Conditions	Field Validation Notes
`Item_or_Service_Description`	[Should look familiar to the customer. Fees can be line items.]	Required for each line item	This should clarify what the customer purchased. You can include additional line items for fees when applicable. This information is critical for detailing the goods or services provided.
`Quantity`	[Display as number]	Required for each line item	Provide the number of line items.
`Unit_Price_Excluding_Taxes`	[Display in selling currency]	Required for each line item	Provide the unit price in the selling currency.
`Line_Item_Total_Excluding_Taxes`	[Display in selling currency]	Required for each line item	Multiply unit price times quantity; while not strictly mandated by every country, we recommend it for all countries.
`LI_Jurisdiction_Applicable_Tax_Rates`	[Display as percentages per juridiction]	Required for each line item and each jurisdiction, in jurisdictions with tax obligations	Tax rate per line item, per jurisdiction, is required data in taxable jurisdictions. While a combined tax rate often complies with global specifications, some countries may require individual rates. Therefore, breaking out each tax rate per jurisdiction, per line item, is required to develop a single solution that remains globally compliant. Complete details are beyond the scope of this version of this document. Many global standards (e.g., Peppol BIS Billing 3.0, UBL, Factur-X) support either: • Combined tax rate per line (e.g., 19% VAT total), or • Multiple tax components per line (e.g., federal + provincial). Systems may break out: • VAT vs. municipal taxes, or • Base + surcharges (common in Brazil, India, and Canada). Peppol and similar XML schemas support tax subcomponents, and some jurisdictions may prefer this granularity for tax audits. Other considerations: • Brazil requires detailed tax components per item (ICMS, IPI, PIS, COFINS). • India splits tax between CGST and SGST/IGST depending on interstate status. • US states may require detailed reporting of local taxes.
`LI_Jurisdiction_Tax_Amounts`	[Display in selling currency]	Required for each line item and jurisdiction in jurisdictions with tax obligations	Display the tax amount for each line item per jurisdiction in the selling currency. Essential for B2B tax reporting.
`Line_Item_Total_Including_Taxes`	[Display in selling currency]	Required for each line item	Provide the sum of line item amounts in the selling currency.

`} ## Totals section The totals section displays the financial amounts related to the transaction. The section includes the following field identifiers: | Field Identifiers | Field Contents | Presentation Conditions | Field Validation Notes | Data References | | :------------------------------- | :----------------------------- | :--------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------ | :-------------- | | `Order_Subtotal_Excluding_Taxes` | \[Display in selling currency] | Required | Essential for calculating the base amount before taxes (even if tax amounts are zero). | | | `Order_Total_Tax_Amount` | \[Display in selling currency] | Required in jurisdictions with tax obligations | Necessary for tax reporting and compliance. Clearly stating the total tax amount helps both buyer and seller in their accounting processes. | | | `Grand_Total_Including_Taxes` | \[Display in selling currency] | Required | This value represents the total amount payable by the customer, including taxes. This field is a standard requirement on invoices globally. | | ## Payment section The payment section shows the customer's payment information. The section includes the following field identifiers: | Field Identifiers | Field Contents | Presentation Conditions | Field Validation Notes | Data References | | :-------------------- | :------------------------------- | :---------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :-------------- | | `Payment_Information` | \[Varies per payment instrument] | Required | It is important to provide the payment Instrument and terms by including clear payment metadata for reconciliation and audit purposes. The payment metadata may include the payment method used (e.g., credit card, digital wallet), transaction reference number, and confirmation of payment completion. Even when no further action is expected from the customer, including this information helps align the invoice with financial records. If the customer has not yet paid, this section should instruct them on completing their payment (e.g., wire transfer). | | ## Customer service section The customer service section provides contact information that the customer can use to get help. The section may include the following field identifiers: | Field Identifiers | Field Contents | Presentation Conditions | Field Validation Notes | Data References | | :------------------------------- | :----------------------------- | :---------------------- | :--------------------------------------------------------------------------------------------- | :-------------- | | `Customer_Service_Email_Address` | '\[email address] | Optional | Provide the email address where customer can send their questions, comments, and concerns. | | | `Customer_Service_Phone_Number` | '\[international phone number] | Optional | Provide a phone that customers can call to ask questions, share comments, or express concerns. | | | `Customer_Service_Website_URL` | \[website URL] | Optional | Provide the URL for the customer service web portal. | | ## Footer section The footer section appears at the bottom of the invoice. The section may include the following field identifier: | Field Identifiers | Field Contents | Presentation Conditions | Field Validation Notes | Data References | | :----------------------------------- | :----------------------------------- | :---------------------- | :--------------------------------------------------- | :-------------- | | \[Your company's footer information] | \[Your company's footer information] | Optional | Do not repeat information about Reach in the footer. | | # VAT and GST reference The following table shows the required field patterns for a B2B digital goods invoice and the B2B transaction task per country. {`
