How to handle tax when your customer is a business

A company buys your downloadable template, then asks for an invoice with its VAT number. You have the payment confirmation, the customer’s email and the product delivery record, but not much else. Before you issue anything, you need to work out which details identify the buyer, whether tax should be added and what evidence you need to keep.

Start by identifying the customer

“Business customer” is not a complete tax classification. A sole trader, limited company, charity or public body may each have different registration and invoicing requirements. The first job is to establish who bought from you and where that customer belongs for tax purposes.

1. 1Ask for the customer’s legal name, rather than relying only on a brand name or the name of an employee placing the order.
2. 2Collect the billing address and country. For a company, this may not be the same as the address of the person downloading the product.
3. 3Provide a field for a tax registration number where it is relevant to your market, such as a VAT or GST number.
4. 4Keep the customer’s email address and the order reference so you can connect the invoice to the transaction.
5. 5Check the number and the customer’s details using the relevant official validation service when your tax rules require or permit it.

Do not treat an empty tax-number field as proof that the customer is a consumer. The buyer may be a business that is not registered for VAT or the equivalent tax. Your records should show what the customer told you and what you used to make the tax decision.

When reverse charge may apply

Reverse charge usually means the seller does not add the relevant VAT or similar consumption tax to the invoice. Instead, the business customer accounts for it in its own tax return. That does not make the sale tax-free in every sense, and it does not apply automatically to every business buyer.

For example, a business buying a digital download for its own work may be treated differently from an individual buying the same download personally. A company buying access to an online course may also raise questions about the place of supply, the customer’s location and whether the course includes live teaching. The product description and delivery method therefore belong in your tax records, not just on your sales page.

What the invoice and record should show

Your invoice should make the transaction understandable to someone who was not present at checkout. The exact legal requirements vary, but a useful record normally connects these parts:

• Your legal business name and address, plus any required tax registration details.
• The customer’s legal business name and billing address.
• The invoice number, invoice date, payment date and order reference.
• A clear description of the product or service, including the relevant access or supply date where needed.
• The amount, currency, discounts, tax rate, tax amount and total charged.
• The customer’s tax number where supplied and validated.
• The reason tax was not charged, if you applied a reverse-charge treatment or another exemption.
• Evidence of delivery, such as the download being made available, course access being granted or a coaching session being booked.

The phrase used for reverse charge also matters. Your local rules may prescribe particular wording, so use the wording required by the tax authority where you are registered rather than improvising a reassuring sentence. If you sell across several borders, one generic invoice template may not cover every situation.

Set up your checkout without making assumptions

A checkout can collect the facts you need, but it should not encourage a customer to choose a tax treatment simply because it lowers the total. Use separate fields for business name, billing address and tax number. Make the tax-number field optional only when that matches your process, and explain what the customer should enter.

With store.fan payments, your sales can go straight to your own Stripe account, while Stripe’s own processing fee still applies. That helps keep the payment trail connected to your business, but you remain responsible for deciding what tax to charge and what records to retain. If you sell downloads, for instance, you can pair your checkout process with a digital product delivery workflow and keep the order reference tied to access.

A practical review before you file

At the end of each reporting period, review business orders rather than waiting for a customer or tax authority to find a gap. Compare your payment records with invoices and look for missing addresses, inconsistent tax numbers or sales where the product type was recorded too broadly.

• Filter orders by customer country and tax treatment.
• Check that every business invoice has a unique number and a matching payment.
• Separate refunded, cancelled and partially delivered orders from completed sales.
• Review whether a customer changed its billing details after purchase.
• Export and store the supporting records in a format you can retrieve during the required retention period.

If business sales are becoming a regular part of your work, build the information request into the buying journey rather than chasing details afterwards. Store.fan can give you a storefront for digital products, courses and other offers, with paid plans starting with a 14-day trial. The platform can organise the sale; your tax process decides what the sale means.
