An easily understandable breakdown of services helps you avoid the client asking questions that can delay the process.

Include your business name, address, phone number, and email address at the top of the invoice. This is your contact information, so the client knows who to reach regarding the invoice.

17. Review and Proofread:
Before sending the invoice, carefully review it for accuracy, clarity, and completeness. Ensure that all calculations are correct.
19. Keep a Copy:
Maintain a copy of the invoice for your records. This helps with tracking payments and maintaining a clear financial history.
Inv oice Numbers
An invoice number is a unique identifier that should be included on every invoice. This helps make it easy for you and your customer to track payments and find related records.
There are a few different ways to format an invoice number, and the system you choose will depend on your business needs. For example, you might use a system that includes the year in the number (e.g. 2020-001, 2020-002) or a project code (e.g., a sequence of invoices might start with ‘WAB25’).
Another popular option is to use a system that includes your company name in the number. This can help differentiate your invoices from those of other businesses, and it might improve brand recognition.
I nvoice Issue Dates
An invoice should include all the relevant payment terms and due dates. This helps ensure clients know their responsibilities, such as paying taxes and fees, and when they are expected to pay.
Invoices should also note any credits, refunds, or late charges that apply. For example, if you offer a 3% cash discount, the invoice should note this.
The date an invoice was issued is the invoice issue date, while the date when goods or services were delivered is known as the supply date. Invoice terms like “3/10, net 30” are commonly used and can be shown on an invoice using different date intervals.
Invoice Supply Dates
When a business provides goods or services, it needs to be able to track these transactions. One way to do this is by using an invoice.
A vital component of an invoice is its payment terms. These dictate when a customer is expected to pay and serve as the basis for late fees, if applicable.
Most businesses use payment terms such as net 30 or 60, but these can vary depending on the industry and customer contract terms. Adding these terms to the invoice makes it easier for customers to recognize when their payment is due. This helps to streamline the process and reduce the likelihood of late payments.
Payment Terms
An invoice’s payment terms are a vital part of its structure. They establish the timeline you expect a customer to pay and can help you avoid disputes and get paid on time.
A professional-looking invoice sets clear expectations for you and the client, reducing the risk of misunderstandings leading to delays in remitting payments. It’s also essential to include the payment methods you accept so your customers know their options.
Listing all line items, including their descriptions and costs, is also essential. This eliminates confusion and unnecessary back-and-forth, resulting in faster payments.
Taxes
Taxes affect your invoice in ways you might not expect. For example, when M&Y Developers paid for concrete for their home improvement project, they had to pay sales and use taxes – even though the company included it in the invoice.
Legal Details
Invoices should include your and your customer’s business name, address, a breakdown of the services or products provided, pricing and subtotals, and any applicable tax. Checking that these details are accurate can help you avoid costly mistakes.
Odoo’s tax engine uses a set of default taxes based on your location, which you can change in Settings. You can also add specific taxes to an invoice or package item.
