Invoices create an agreement between you and your customer and make sure you get paid for the products you sell. Each sales invoice outlines the products and amounts you sold, when you sold them, for what prices, and when payment is due.
This guide shows you what invoices are, why you need them, what to include on your invoices, and how to streamline the electronic invoicing process as a business owner.
What is an invoice?
An invoice is a legal document that itemizes and records each transaction between your business and your customers. It confirms and logs the products a customer bought and the amount they have agreed to pay for those products.
Invoice vs. bill
A bill records a sale that the customer pays right away. Unlike an invoice, which often has detailed payment terms and other information, a bill is a simple statement of what’s due for payment now.
Invoice vs. purchase order
Purchase orders work the other way around: they detail the items a buyer wants to purchase at a certain price point. As a small business, you’d issue a purchase order when ordering large product quantities from a supplier.

Different types of invoices
Recurring invoice
Recurring invoices are issued to customers at regular intervals for repeat transactions. Some examples include subscription box services or a yearly delivery subscription, likethe one ASOS offers.
Pro forma invoice
A pro forma invoice shows the price of goods and records the commitment of the seller to deliver the goods. It’s issued in advance and allows the buyer to plan for the purchase, as well as to calculate customs fees before buying.
Timesheet invoice
Timesheet invoices are issued to charge for work done on an hourly basis. It includes the number of hours worked and the hourly fee to make up the total invoice amount.
Credit invoice
A credit invoice is issued when you need to give a customer a refund or a discount, usually when customers make areturn. It’s also called a credit note or credit memo. This invoice reverses a charge from a previous invoice.
Debit invoice
A debit invoice notifies the buyer of their current debt obligations. It’s also called a debit note. It’s issued when you need to increase the amount a customer owes you. For example, they ordered a product and received an invoice from you, but changed their order to a higher amount at a later date.
Commercial invoice
Commercial invoices are crucial for international sales. They’re used for customs declaration and customs fee calculation when products are exported across international borders.
A commercial invoice needs to outline full contact details of both the issuer and the buyer, contents of the package and its value, size and weight, country of origin, the reason for export, order date, and sender’s signature.
Interim invoice
Interim invoices are issued for milestones during a large project. They act as partial payments and allow both the seller and the buyer to better manage their cash flow.
Past due invoice
过期的发票是没有发票paid on time. Late payments can have a huge negative impact on your cash flow and, as a result, your business—i.e. your ability to pay your staff, rent, and suppliers. Stay on top of your accounts receivable to avoid past due invoices.
Retainer invoice
Retainer invoices are issued to collect advance payments for products or services. It’s a form of invoicing for a deposit, allowing you to confirm a commitment from a customer.
Elements of an invoice
Your invoice format will depend on your bookkeeping needs, your local regulations, and the type of store you run. Here's what a typical invoice example looks like.
Keep the following elements in mind when creating your invoice template:
1. Invoice terminology
First, make sure you include the word “Invoice” at the top of the document. Make it easy to see and impossible to confuse with a different document, like a purchase order or a credit note.
This is not only for practical reasons; it’s a legal obligation for business-to-business transactions in most countries.
2. A unique invoice number
Each invoice document should have its own reference number, and your bookkeeping system should keep a record of the numbers used. Your customers will use your invoice numbers to keep track of invoice payments on their end.
Assign numbers to invoices sequentially, starting from the lowest (1 or 0001, for example) and assigning the next number to each invoice that follows.
You can also use letters in your unique invoice number to facilitate categorization and clarity.
3.你的公司信息
Every invoice needs your business information on it: company name, address, phone number, and email address. Include your VAT ID if you have one and it’s applicable to the transaction. This should be positioned at the top of the invoice.
These details also help your customer keep correct information on file.
4. Customer information
Customer information also goes at the top of your invoice and reflects the format of your company information. Include the customer’s name, billing address, shipping address (if different than billing address), phone number, and email address.
5. Invoice date
Invoice creation date is crucial. It usually determines the payment due date, and indicates if the invoice is overdue and needs your follow-up.
6. Names and descriptions of products sold
This is the main part of your invoice, as it makes up the total amount due and indicates the products your customer ordered from you.
Each unique type of product—for example, a combination of a selected color and size—gets its own line on the invoice. Each line item should also have these columns:
- Description of the goods.Add a short product description and/or the product’s SKU number.
- Quantity.年代pecify how many units of a product the customer ordered.
- Unit price.The price of a single unit of a product.
- Line total.Unit price multiplied by the quantity.
7. Sales tax
年代ales tax depends on your state and the types of products you sell as a retail business. Once you determine whether you need to charge for sales tax and how much, you need to include it in your invoice.
Here’s aregularly updated tablewith sales tax rates per state.
8. Total amount due
这个数字应该脱颖而出information on your invoice—it’s the most important piece of information for your customer, and a reason you’re issuing an invoice in the first place.
Add up your line totals into a subtotal amount. If you don’t charge sales tax or VAT, this is also your total amount due.
If you need to charge sales tax, indicate the sales tax rate you’re charging, multiply the subtotal by the sales tax rate, and add the result to the total due.
For example:
- 年代ubtotal: $100
- 年代ales tax rate: 7%
$100 x .07 = $7 → The sales tax amount for this invoice
$100 + $7 = $107 → The total amount of this invoice (subtotal + sales tax amount)
9. Terms of payment
invoic明确你的付款条件e. This removes any guesswork or unspoken expectations of your customers.
Here are some common terms of payment you can use:
- Net X.Payment within X days from invoice date. These are most often net 7, net 30, net 60, and net 90. Customers will often wait until this date to make their payment.
- Payment in advance (PIA).Payment in full before you fulfill their order and complete the work.
- Cash in advance (CIA).年代imilar to PIA, but the payment is made in cash before you fulfill the order and complete the work.
- Upon receipt.You expect payment when the customer receives the invoice, usually the next business day.
- End of month (EOM).Payment by the end of the same calendar month the invoice was issued in.
- 15th of month following invoice (15MFI).Payment by the 15th of the month after the invoice date.
- 50% upfront.You ask for 50% of the total invoice amount before you fulfill the order and complete the work. This is usually used for larger orders and projects.
10. Payment details
Outlining payment details is a great way to make paying supplier and customer invoices easier.Nearly 50% of customerswho can’t use their preferred method of payment will abandon the payment process, so this section of your invoice is worth setting up and making flexible.
11. Shipping terms
Finally, include your shipping terms, including who’s responsible for the shipping costs.
Include details about the method of shipping, expected delivery date, and tracking information.
