Different types of Invoices
Standard invoice:
A standard or a customary invoice is prepared by a company and sent to a customer. This is the most popular invoice format used by entrepreneurs, and it can be customised to meet most sectors and billing cycles.
Debit invoices:
A debit invoice, also known as a debit memo, is sent by a company that needs to raise the money owed to them by a customer. When small businesses and entrepreneurs need to make a minor change to an existing bill, debit invoices might be helpful. For instance, if you submitted an invoice to a customer, based on your projected hours and you ended up working more hours on a project than you anticipated, You may issue a debit invoice to the customer for the additional hours billed. A positive total amount should appear in the debit invoice.
Credit invoice:
A credit invoice, also known as a credit note, is sent by a company that has to offer a discount or refund to a customer, or to remedy a prior invoicing error. A negative total amount must always appear on a credit invoice. For example, if you’re sending a customer a credit invoice for a $100 refund, the amount on the credit invoice will be -$100.
Mixed invoices:
When Credit and debit charges are combined on a single invoice, and the total amount might be represented as a positive or negative figure then it is named as a mixed invoice. Small companies seldom need to produce mixed invoices for their services, but it may be required if you’re lowering the amount owed for one of the projects you’re billing for while raising the amount owed for another project invoiced on the same invoice.
Commercial invoice:
A commercial invoice is a document produced by a company for items it sells to clients all over the world. Commercial invoices provide information about the sale that is essential to calculate customs taxes for cross-border transactions.
Timesheet invoice:
A timesheet is an invoice that is used when a company or employee bills based on the number of hours worked and their hourly rate of compensation. Contract employees who are paid hourly by their company utilise timesheets. Businesses where clients are charged by the hour, such as:
- Consultants in business
- Psychologists
Pro forma invoice:
A pro forma invoice is a pre-payment estimate that a company provides to a customer before performing services. A pro forma invoice gives the customer an idea of the cost of the work that has to be done. Changes may apply after the service is completed.
Interim invoice;
An interim invoice is used for invoicing on major projects where the client and the company have agreed to numerous payments. When various benchmarks in a bigger project are accomplished, a company or freelancer will provide interim bills. Interim invoicing assists small firms in managing their cash flow while working on long-term operations.
Past-due invoice:
If a client fails to pay by the due date specified on the final invoice, a firm will send a past late invoice. As soon as a client misses a payment deadline, you should send them past due invoices.
Recurring invoices:
Businesses that usually charge the same price for their services on a regular basis will benefit from recurring invoices. IT companies that bill their clients the same amount each month for a bundle IT service use recurring invoicing.
