If your business issues B2B invoices in Estonia, two different layers of rules apply, and which one governs your invoice depends on a single fact: whether the seller is VAT-registered. Every invoice, regardless of that status, has to meet the bare minimum set out in the Accounting Act<\/a>: the transaction date, a clear description of what was sold, and the figures (quantity, price, amount). Once the seller is registered for VAT, section 37 of the VAT Act<\/a> adds ten further mandatory fields, including the buyer’s VAT number (their k\u00e4ibemaksukohustuslase registreerimisnumber, the VAT identification number used on cross-border sales) and the VAT amount stated in euros. Estonian law doesn’t prescribe one official invoice template; what matters is the content, not the layout or a signature.<\/p>\n

Where do you start: transaction type or invoice template?<\/h2>\n

Before you start checking individual fields, answer three questions: is the seller VAT-registered, is the buyer a business or a private person, and does the transaction stay inside Estonia or cross a border? If the seller isn’t VAT-registered, the Accounting Act’s<\/a> minimum for a source document is enough on its own. Once the seller is VAT-registered, the VAT Act’s stricter list kicks in, and cross-border transactions bring extra notes on top of that.<\/p>\n

What’s the floor for every B2B invoice: time, content, amount, parties?<\/h2>\n

Regardless of the seller’s VAT status, every B2B invoice has to contain at least four things under section 7 of the Accounting Act<\/a>: the date the transaction took place, a clear description of its economic substance, the figures (quantity, price, amount), and, if the buyer is itself subject to accounting obligations, a public-sector accounting entity, or a foreign legal person, an invoice number plus details identifying both parties.<\/p>\n

There is no mandatory invoice template. A signature isn’t a required field either, and that includes self-billing, where the buyer issues the invoice instead of the seller. The seller is free to accept an invoice without a signature, as the Estonian Tax and Customs Board<\/a> explains.<\/p>\n

What ten extra fields apply once the seller is VAT-registered?<\/h2>\n

Once the seller is registered for VAT, section 37(7) of the VAT Act<\/a> adds ten fields:<\/p>\n

    \n
  1. The invoice’s sequence number and date of issue<\/li>\n
  2. The seller’s name, address and VAT number<\/li>\n
  3. The buyer’s name and address<\/li>\n
  4. The buyer’s VAT number, if the tax liability shifts to the buyer<\/li>\n
  5. The name or description of the goods or service<\/li>\n
  6. The quantity of goods or the scope of the service<\/li>\n
  7. The date of delivery, service, or advance payment, if it differs from the invoice date<\/li>\n
  8. The net price and any discount not already included in the price<\/li>\n
  9. The taxable amount broken down by VAT rate, and the rate applied<\/li>\n
  10. The VAT payable, stated in euros<\/li>\n<\/ol>\n

    Points 4 and 7 only apply when their condition is met. They’re also the two that most often get left off invoices even when they should be there.<\/p>\n

    When does an invoice need an extra tax reference or note?<\/h2>\n

    Four situations need something beyond the standard fields:<\/p>\n
