What is an Invoice? 

An invoice is a financial document businesses, freelancers, and agencies use to request payment. It contains an itemized list of services rendered or goods supplied, associated costs, payment terms, and other relevant details that help businesses track transactions for financial reporting and record keeping.

Traditionally, businesses used paper-based invoices and postal services for delivery. Modern financial document automation platforms like Docupilot provide an alternative for the fast and efficient creation and delivery of digital invoices.

How to Create an Invoice  

Invoices are critical to business accounting processes and must comply with accounting standards for accuracy, consistency, fraud prevention, legal, and tax compliance purposes.

• If you are in the US, you need to adhere to Generally Accepted Accounting Principles (GAAP) standards issued by the Financial Accounting Standards Board (FASB)
• If you are outside the US, you need to comply with International Financial Reporting Standards (IFRS) developed by the IFRS Foundation

Elements of an invoice  

Some of the common elements you must include in an invoice when requesting payment include:

• Statement of the invoice: To prevent any ambiguity, an invoice must include a clear title at the top
• Invoice number: A number unique to each invoice that serves as an identifier for current and future reference
• Invoice date: The date of the invoice
• Contact information: Names, addresses, and contact details, and depending on the applicable accounting standard, the tax identification number of the vendor and/or client
• Itemized list of goods and/or services rendered: Detailed list of goods and services provided, with the associated cost of each item
• Currency: Especially for international transactions, an invoice must specify the currency relevant to the transaction
• Taxes, fees, and penalties: These include charges that can affect the total amount requested, such as applicable taxes, late fees for other invoices, and credits for advance payments
• Total amount due: The total amount requested, which includes the cost of goods or services, and applicable charges such as taxes
• Payment terms: These are usually agreed upon before the transaction and are included in the invoice for the sake of clarity and completeness. Depending upon the mutual agreement, businesses can agree to pay in full or in installments 
• Payment mode: Vendors can specify acceptable payment methods, such as cheque, bank transfer, PayPal, credit card, etc.

Types of Invoices 

There are several types of business invoices. Each type of invoice suits a different business scenario and transaction structure.

Here are the most common types of invoices:

Standard invoice

The most common type of business invoice is a standard invoice (aka sales invoice). Businesses use standard invoices for regular transactions. They include a list of goods/services provided, their quantity, price, tax information, and total amount due.

Proforma invoice

A pro forma invoice is not a payment request. Rather, it is a document a vendor sends to a client before providing goods or services. Customers sometimes require this type of invoice as a documented estimate of projected costs, payment terms, and any other factor affecting the overall cost of a project or purchase. Client approval of a pro forma invoice indicates acceptance of the projected costs and associated terms and conditions.

Interim invoice

For large projects spanning lengthy durations, it is often not feasible for a client to pay the full amount against a single invoice. For such projects, the vendor and client usually agree upon a payment schedule. The client makes payments against interim invoices sent according to the agreed-upon schedule. This arrangement ensures the vendor does not suffer from cash flow problems and can continue to complete work while receiving periodic payment.

Recurring invoice

Recurring invoices are commonly used when a vendor or service provider charges a client the same amount after a predetermined time. A common example is the invoice for a monthly or yearly SaaS subscription fee sent by the SaaS provider to its customers. When you use a financial document automation platform like Docupilot, you can set up automated workflows to deliver digital invoices to your customers on specified dates for a specified duration.

Final invoice

A final invoice is a document sent by a vendor to a client upon project completion. It usually contains more details than an interim invoice and signifies the final amount due for closing the transaction.

Overdue invoice

Cash flow constraints, operational issues, economic instability, and a host of other reasons can affect a business's ability to pay invoices on time. Even when an invoice contains all relevant and necessary details, there is no guarantee that a request will be honored on time.

Vendors can pursue a range of legal remedies, ranging from informal reminders to formal actions such as filing lawsuits or engaging collection agencies, to collect outstanding dues. However, the first option is usually an overdue invoice to remind customers of payment delays. These invoices can include late payment fees, proposals for staggered payments, etc.

Timesheet invoice

Lawyers, freelancers, creative agencies, consultants, contractual employees, and other professionals working on an hourly basis normally use a timesheet invoice to request payment. This type of invoice provides a detailed breakdown of projects or services worked on, the number of hours worked, the hourly rate, and the total amount requested.

Invoicing Mistakes to Avoid

Invoicing mistakes can lead to delayed payments, misunderstandings, and damaged business relationships.

Here is a list of common invoicing mistakes to avoid.

Not sending invoices promptly

This might seem obvious, but unfortunately, it is a common mistake.

The best practice is to send invoices immediately after delivering goods or services. However, even when a business has proper systems, processes, and procedures in place, the likelihood of not sending invoices or sending them late remains high due to human oversight, miscommunication, or inefficient manual invoicing processes.

This is where financial document automation can provide an effective remedy: once a workflow is set up, you can rest assured that detailed invoices will be delivered on time, along with notifications to ensure relevant stakeholders take prompt action.

Lack of professionalism

Every interaction between a vendor and a business, whether it involves people or documentation, creates an impression. It takes several positive impressions to develop trust and goodwill, while a single negative impression can overshadow and demolish trust and goodwill.

A professional invoice demonstrates that you mean business, whereas an unprofessional invoice - with mistakes, missing information, or sloppy formatting - can create mistrust and destroy your client's confidence in your abilities to deliver high-quality work.

Incorrect or missing information

‍

Businesses are cautious with finances, which is understandable. They have a natural incentive to manage cash flow and prefer to retain funds for longer whenever possible

Invoices with mistakes, omissions, and inaccuracies are proof of sloppy workmanship and give businesses a valid reason to delay payments and create disputes.

So make sure to dot the i's and cross the t's. Accurate and detailed commercial invoices are not only a necessary business practice, but they can be the difference between a thriving business with healthy cash flows and one that sinks as it flounders from one mistake to another.

Unclear payment terms and policies

Option 1: "Payment is due soon after receipt of the invoice."

Option 2: "Payment is due 30 days from the date of the invoice, with a 2% late fee applied for payments received after this period."

Which option do you think will get you the payment on time? And there are no prizes for guessing the right answer!

Failing to provide multiple payment options

A client may have sufficient funds in their bank account. Another might be short of funds but have a credit card with a high credit limit. Yet another one might prefer to pay via PayPal.

Don't limit payment options. Do the necessary research on your clients, their financial practices, and preferences. This will help you collect payments on time, enabling you to keep delivering high-quality work and growing your business.

What are Digital Invoices and Why Are They Better?

"Digital," "Digital Transformation," and "Digitization" are not mere buzzwords people fancy: they refer to modern business practices that help streamline business operations, reduce costs, and positively impact the bottom line.

If you want, you can stick to old-school paper invoices which take an inordinate time to create and must be delivered by hand or courier to each client.

Or you can transition to digital invoices that offer numerous benefits for business operations.

Lower costs

All the benefits of electronic invoices can be summed up into one big benefit: lower costs. When you switch to digital, you save on

• Costs associated with paper procurement, storage, and printing
• Mail/courier delivery costs
• Late payment/opportunity costs arising from late invoice deliveries
• Administrative costs related to time and effort spent chasing up payments or reissuing invoices
• Operational costs, such as business operational disruptions due to delayed cash flows, impacting the ability to pay suppliers and employees or invest in new opportunities

Reduced risk of human error

Variety, as the saying goes, is the spice of life,

We humans crave novelty, creativity, and freshness. Repetitive tasks, like creating invoices one after another, lead to monotony, disinterest, and ultimately, mistakes.

But mistakes in invoices can be costly, if not downright dangerous.

Computers and invoicing software, in contrast to humans, are built for repetitive tasks: customized and approved invoice templates populated with data pulled from relevant sources, sub-millisecond numerical calculations, and checks for missing/inaccurate information simplify and speed up invoice creation, minimize errors, and ultimately, help you collect payments on time.

Integration with digital systems for search, audits, and documentation

When you go digital, you can take advantage of your digital ecosystem to

• Send and store invoices securely
• Integrate with analytics systems for analysis and reporting
• Easily search and locate invoices for reference, documentation, and audit purposes

FAQs

Is an invoice proof of payment?

An invoice is not proof of payment: it is  a payment request and specifies goods and/or services rendered for which payment is due.

Is an invoice a bill or a receipt?  

Vendors use invoices or bills to request payment. After receiving payment, vendors issue receipts as proof of payment.

What is the difference between an invoice and a bill?

The terms "invoice" and "bill" are often used interchangeably. However, differences between the two include, but are not limited to, the following:

• Invoices are common in B2B transactions, whereas bills are common in B2C transactions
• Compared to bills, invoices are more detailed documents
• A bill is issued immediately after product/service delivery and the seller/provider expects immediate payment. Invoices are issued sometime after product/service delivery and include payment terms that can specify payment at a later date
