Checklist for Reviewing Electronic Invoices Before Sending to Customers (To Avoid Errors)

Electronic invoices are not only legal sales documents but also reflect the professionalism of your business to customers. An invoice with errors can lead to many undesirable consequences such as loss of reputation, subsequent invoice adjustments, or even tax disputes.

In reality, many retail shops and businesses often issue invoices in haste, leading to errors in customer information, incorrect amounts, or missing mandatory elements. These mistakes not only waste time on corrections but also affect the customer's purchasing experience.

To help you avoid these risks, this article provides a detailed checklist to thoroughly review before sending an electronic invoice to a customer. Each checking step is important and needs to be performed carefully to ensure the invoice is accurate, valid, and professional.

Why is it important to carefully check invoices before sending?

Checking invoices is not just about avoiding administrative errors. It's a crucial factor that directly impacts your reputation and business operations. An accurate invoice helps customers feel secure and trust your work.

Legally, electronic invoices with errors may require your business to go through complex adjustment or cancellation procedures according to tax regulations. In some serious cases, invalid invoices may result in administrative penalties or be ineligible for tax deductions.

From an operational perspective, having to correct invoices after they have been issued disrupts workflow, costing both you and your customers time and effort. Furthermore, if the customer has already used the invoice for tax declaration, adjustments become even more complicated.

Detailed Checklist for Reviewing Electronic Invoices

1. Check Seller Information

The first and most important step is to ensure your business information is complete and accurate on the invoice. This includes the business name or individual name that must exactly match your business registration and electronic invoice issuance notification:

• The seller's tax code must be clearly and accurately printed.

• The business address needs to be complete, including house number, street name, ward, district, and province.

• Contact phone number and email should also be checked to ensure customers can reach you when needed.

• Bank account information, if listed on the invoice, needs to be re-verified to avoid confusion during customer transfers.

2. Check Buyer Information

Buyer information is the most common area for errors as it is often manually entered from customer data. - The buyer's name or company name must be accurately recorded according to legal documents, avoiding abbreviations or missing diacritics.

• The buyer's tax code must be accurate and cross-referenced with the General Department of Taxation's portal to ensure validity.

• The buyer's address must also be fully recorded, which is particularly important for businesses. In some cases, the address on the invoice may differ from the actual delivery address, and this needs to be clarified to avoid future confusion.

• The buyer's phone number and email should be re-checked to ensure you can contact them when needed to send the invoice or handle arising issues. If contact information is incorrect, the invoice may not reach the customer on time.

3. Check Goods and Services Content

Information related to the content of goods and services you need to check includes: - The name of the goods or services on the invoice must be clearly, fully, and accurately described to match the transaction. Avoid generic terms like 'goods' or 'services' without specific details, as this can make it difficult to reconcile with contracts or other documents.

• The unit of measure must be clearly stated, such as pieces, boxes, kg, liters, hours, months, depending on the type of goods or services. An incorrect unit of measure can lead to misunderstandings about the actual quantity purchased.

• The quantity of goods or services must exactly match the order and the delivery note. This is a common error when the invoice issuer enters the wrong quantity or fails to update the quantity after customer changes.

• The unit price and total amount need to be carefully checked. The unit price must match the quote or prior agreement with the customer. The total amount must be calculated accurately by multiplying the quantity by the unit price, and attention should be paid to rounding if applicable.

4. Check Tax Rate and Tax Amount

The applicable tax rate must comply with current legal regulations for each type of goods or service. Currently, common tax rates are 0%, 5%, 8%, and 10% depending on the industry. Certain goods that are not subject to value-added tax or are exempt from tax must also be correctly identified.

The value-added tax amount must be calculated accurately based on the taxable base and the tax rate. You need to re-check the calculation formula to ensure there are no errors, especially when the invoice includes multiple items with different tax rates.

The final total payment amount must equal the total cost of goods plus the value-added tax. This is the most important figure customers care about and the basis for payment, so it requires extremely careful checking.

5. Check Invoice Symbol and Number

The invoice symbol must match the symbol accepted by the tax authorities when the issuance was notified. Each type of invoice has its own symbol, and you need to ensure you are using the correct invoice type for the corresponding transaction.

Invoice numbers must be sequential and not duplicated. Electronic invoice software systems typically auto-increment numbers, but you should still check to ensure no technical issues have caused duplicate or abnormal numbering.

The invoice date must correspond to the time the tax liability arises, usually the date of goods transfer or service completion. Incorrect dating can affect the tax declaration period for both the seller and the buyer.

6. Check Digital Signature and Verification Code

A valid electronic invoice must have the seller's digital signature. You need to ensure that the digital signature is valid and has not expired. If the digital signature has expired, the invoice will not be accepted by the tax authorities.

The verification code from the tax authority or the electronic invoice service provider must appear on the invoice. This element confirms that the invoice has been sent and accepted by the system, ensuring its legality and traceability.

The QR code or the invoice lookup link should also be checked for functionality. Customers can scan the QR code or access the link to verify the invoice's authenticity on the tax authority's portal.

7. Check Invoice Format and Appearance

The invoice template must comply with the issuance notification approved by the tax authorities. Modifying the invoice template without authorization may render the invoice invalid according to legal regulations.

Mandatory information must be displayed completely and clearly on the invoice. According to regulations, invoices must include all elements such as the invoice type, template code, invoice symbol, invoice number, seller's information, buyer's information, transaction details, digital signature, and verification code.

The font and font size should be checked to ensure readability. Some invoices printed or sent as PDFs with text that is too small or unclear can make it difficult for customers to use.

8. Final Check Before Sending to Customer

After reviewing all the above elements, you should re-examine the entire invoice from the customer's perspective. Ask yourself if there is any information that might cause confusion or require clarification if you were the recipient.

If the invoice will be sent via email, double-check the recipient's email address and ensure the attachment is in a standard format like PDF or XML. The email subject line and body content should also be written professionally and clearly.

If the invoice is to be printed and handed over to the customer, check the print quality to ensure all information is sharp and not blurry or smudged. The invoice should be folded neatly or placed in a suitable envelope to demonstrate professionalism.
