Types
There are various kinds of invoices, each serving a distinct role. The most common types are:
1. Standard
This is the most common option most businesses use as it has a flexible format that they can easily customize, and it works for almost every industry. It simply provides a detailed breakdown of goods or services offered, including prices.
2. Sales
It is another common type. The seller sends this to the buyer once the sale is over. Along with the seller and buyer’s information, an itemized list of goods and services, and price, it might also include the payment link for the buyer.
3. Credit
It is also known as a credit memo or credit note. This comes into use when a buyer has returned an item or has accidentally overpaid, so the seller sends them a credit notice to offer a refund.
4. Debit
It is the complete opposite of a credit memo. While a credit memo offers a refund, the seller sends the debit memo to ask for additional charges. This can happen if the seller changes the order quantity or quicker delivery time. However, a seller must request the customer’s approval before issuing a debit memo.
5. E-Invoice (Electronic Invoice)
Instead of paper, these invoices use digital formats like PDF or specialized e-invoicing systems, which enhance efficiency and reduce paper-based processes.
6. Proforma
This is a preliminary invoice. A vendor sends it to the buyer before delivering the actual goods or services. It is to give the buyer an estimate of how much it can cost and also clarify the sale’s terms.
7. Retainer
Service providers use this to ask clients to make an advance payment. It guarantees that the business will provide the service at a future date.
8. Interim
It is also called an intermediate or a progress invoice. Vendors use this during a long-term project to request partial payment for the work already done.
9. Final
A vendor sends this after completing the entire project or delivering all the goods. It includes all costs and expenses related to the delivered goods or services, along with any applicable taxes and additional costs.
10. Past-Due
Sellers send this to remind clients of unpaid bills that have exceeded the due date, typically including additional late payment fees.
11. Timesheet
Service industries commonly use this type. It details the hours worked by employees or contractors, along with their hourly rates and the total amount due.
12. Commercial
Businesses use commercial invoices for international trade. It also acts as a custom document that outlines who the seller and the buyer are and the items being sold.
13. Recurring
When a buyer often buys the same items in the same quantity from one constant business, the firm sends them a recurring invoice (same repeated invoice). They can send these on a weekly, monthly, quarterly, or annual basis.
14. Mixed/Hybrid
It combines a sales and a purchase invoice and has two sections, one for sales and one for purchase. Businesses use this when they are both the seller and the buyer. For example, if Company A sells chairs and tables to Company B and, at the same time, buys machinery from Company B, they will send a mixed invoice to Company B.
Uses
Invoices serve multiple purposes, including the following:
- Record Keeping: They provide a comprehensive record of transactions, helping businesses and individuals track their financial activities over time.
- Proof of Transaction: They act as evidence of the sale, protecting both the seller and the buyer in case of disputes.
- Legal Compliance: Many countries require businesses to issue invoices for tax purposes.
- Inventory Management: They help businesses monitor their inventory by recording items sold and their respective quantities.
- Payment Tracking: They facilitate payment tracking by specifying due dates and payment methods.
