Your Company Details

Any business should develop and stick to a proper invoice template that works for them. It should start with the branding, which includes the business logo, common fonts, and color palette. 

In the header, below the company logo, you'll write down important information about your business, such as contact details. This will include your company name, address, location, email, and phone number, so your clients and customers can reach you easily for any questions about your service.

Client Contact Details

Following your business information, you proceed to write down your client details. These will include the client or customer name, business address, email, and phone number. 

Include the Invoice Number and Invoice Date

Each invoice you create must include a unique invoice number that is listed in the bill. It works as an ID and is an important reference when discussing or arguing any issue about a specific invoice with the customer. It helps to streamline your bookkeeping process, too.

Don’t forget to include the invoice date. You can list the specific date that you issue the invoice or the billing period instead. The latter depends on the invoicing cycle your business follows.

List Services Rendered

An Invoice should include each of the services rendered in a detailed itemized list, explaining all the services provided for the customer during the billing cycle. 

To do this correctly, you should briefly describe the work done, the hours worked or the quantity provided, the rate of pay for each service, and the subtotal for each service listed. 

Outline Your Payment Terms and Applicable Taxes

Define the payment method you accept for your services. Try offering your clients many options, like cash, credit card, check, and online payments. It will give your customers more flexibility. Be sure to provide all the payment details for all the methods that your business offers.

Also, list clearly any taxes that you have to charge. Different states will require small businesses to charge different amounts of taxes.

Service Invoice Due Date and Total Amount

State a specific due date of payment for your service invoice. Be clear and direct, so there isn't confusion between you and the client. This information should be prominently displayed to catch the attention of your customer. 

Lastly, include the total amount of your services provided. Also, make it clear and prominent so the client won’t miss it.
