Amazon's Invoice Defect Rate: the 5% Rule for Business Orders

In brief: the Amazon Invoice Defect Rate measures one simple duty: Amazon Business customers need a VAT invoice — or a receipt, if the seller isn't VAT-registered — for their own accounts. Amazon began tracking an Invoice Defect Rate from July 2020: the share of business orders with no downloadable invoice or receipt within one business day of shipment confirmation. From 5 April 2021, sellers on Amazon.co.uk, .de, .fr, .it and .es had to keep it below 5%, or risk account deactivation. Invoices sent through buyer-seller messages don't count — they're treated as missing. In April 2024, after a rise in defects over the holiday season, Amazon reminded sellers of the rule.

How to keep your Amazon Invoice Defect Rate down

Method	Who it suits
VAT Calculation Service	VAT-registered sellers; free, automatic invoices
Automatic receipts	Sellers not required to register for VAT in the UK or EU, after declaring their exemption
Upload in Seller Central	Sellers issuing their own invoices, manually or through a third-party tool

Since January 2021, order reports can include the buyer's VAT number, its country, the registration type and the company name, so invoices can show the right customer details.

A worked example

A seller gets 400 business orders a month. If 30 of them lack an invoice within one business day, the Invoice Defect Rate is 7.5% (30 ÷ 400) — above the 5% limit. Getting it under 5% means no more than 19 missing invoices a month.

What it means for your bookkeeping

• Your invoices should match your books. Whatever method you use, the VAT on each business invoice should equal the VAT in your accounts for that sale.

• Buyer VAT numbers matter. Business buyer details from the order report can change the VAT treatment of cross-border sales; take advice where a buyer is outside the UK.

• Not VAT-registered? You still owe business buyers a receipt, without VAT — but you need to be sure you really are exempt from registration.

• Deactivation stops cash flow. A high defect rate can switch off your account, so treat invoicing as part of your month-end checks.

• Match invoices to your books. The VAT you invoice must equal the VAT you record — see Amazon VAT tax codes in Xero and which VAT return boxes apply.
