What's the difference between a bill and an invoice?

There are lots of different payment methods for businesses, so it can be difficult to determine which one is best for you. In this article, we discuss the difference between a bill and an invoice - and when it’s appropriate to use one or the other.

Should I send a bill or invoice?

A bill and an invoice serve similar purposes. They both provide information about the money that your customer owes you in relation to the sale of your products or services to them.

A business owner would normally use an invoice when looking to collect money from a client. You can generate an invoice before or after your client has received your goods or services.

A bill is more of a generic term. You’d give your customer a bill if they were paying for your goods or services, at the point of sale/ use.

Below is a table that highlights the differences between a bill and an invoice.

When to use a bill

As we’ve already outlined, an invoice and bill are similar. But when would you use a bill instead of an invoice?

A bill outlines how much a customer is to pay for goods or services used, unlike an invoice, which can be recurring. A bill has a one-time use. You’d use a bill if you’re charging for goods and services that your customers receive instantaneously. You would be more likely to produce a bill when offering services or products at bars, spas, restaurants or salons.

When to use an invoice

So, what is an invoice and when is it best to use one?

Invoices are a necessary part of your business. They are mainly used to ensure you get paid and as a tax document that acts as proof of income. If you’re selling products and services to clients, you must provide an invoice. If you and the customer are registered for VAT, you’re legally obliged to produce an invoice.

You can use invoices for one-off projects or recurring work. Using an invoice template is an effective time-saving idea that means you won’t need to repopulate the same information over and over again if you’re involved in generating recurring invoices.

The legal difference between an invoice and a bill

There are strict rules around invoices in the UK. This is because they’re legally binding documents and require the inclusion of certain information to be valid. If you and your client are not VAT registered you’ll not need to include a VAT number. But, if both you and the client you are selling to are VAT registered, you’re legally obliged to produce an invoice.

In summary, a bill is a more informal document that usually details services or goods used and paid for at the time of use.
