  • The customer’s name and contact details It must also contain the address where the service or product will be delivered. The details must be similar to the ones submitted to the bank.
  • Tax details and breakup A detailed breakdown of the tax includes provincial tax, goods or service tax, etc. It informs the customer about each tax point of the product or service.
  • Quantity of the goods or services sold. It is easier to chalk out the price breakdown when you know the quantity. It is also a way to ensure the exact weight of the product or part of the service you are receiving.
  • Payment terms and conditions This is a disclaimer about the dos and don’ts related to the payment. This will help the client be sure about the thoroughness of the product. It also mentions the related late payment penalties.

  • The due date of the full payment
  • The total amount and its associated adjustment. In other words, it shows debit and credit. For example, an advance payment, a payment due, any overdue payment, or the remaining amount to be paid. 

Types of Invoices

As you are quite familiar with the hooks and nooks of the invoices now, let’s know about their types:

  • Credit Invoice: The buyer receives it from the seller on account of an earlier mistake in the invoice. It is also issued in the case of a refund. The figure on the credit invoice is always negative.
  • Recurring Invoice: As the term implies, these invoices are issued on a monthly basis. The amount printed in such types remains the same. They are frequently issued for monthly subscriptions or other similar services.
  • Commercial Invoice: It is created when an international transaction happens. These are special invoices. They undergo customs formalities and duty procedures during product shipment.
  • Debit Invoice: The business issues the debit invoice to the customer when there is an enhancement to the invoice. When the company invests more than the estimated amount, it gets reflected in those invoices.
  • Standard Invoice: This is the usual invoice format that is usually followed by businesses. It is generally created to record transactions between businesses, buyers, etc.
  • Interim Invoice: An interim invoice is given to the customer in the middle of an ongoing project. It is just an update to inform you of a milestone achieved ahead of the final goal.
  • Pro-Forma Invoice: It includes the estimated price before the actual price is finalized.
  • Mixed Invoice: The mixed invoice can reflect either the debit or the credit amount. Thus, the amount printed on this invoice will be a positive or negative balance. However, it totally depends on the changes in the accounts.
  • Due Invoice: You must issue this invoice to the customer if he or she has not paid the full amount. A business always issues this type of invoice whenever the customer does not pay in full by the due date.
  • Timesheet Invoice: It is used mostly by hourly employees. This sheet is to keep track of their total workable hours and the pay rate. They create it and send it to the company during the payday.
