An invoice is an accounting document issued by a supplier to request payment from the buyer. It includes the number of items, the prices, the unit price, and the total amount that customers have to pay. An invoice can also be used as a legal record to justify the transaction between a client and a supplier.

As a legal record, an invoice has to contain these important elements:

• the unique invoice number/code (most online invoices will auto-generate the invoice number),
• the invoice date,
• the name of your business,
• the invoicing address,
• the information of the customer (name, address, contact, department, etc.),
• the description of purchase (quantity of items, unit price, description, total amount)
• the total summary (total, subtotal),
• the VAT identification number (if applicable),
• the penalties for late payment,
• the terms & conditions of payment.

The invoice is a commercial document issued in duplicate, to be provided to the customer and kept by the product or service supplier.

Several types of invoices exist. Each invoice has a specific use:

• Standard invoice: This is the most common type of invoice that is issued by a business to its client and can fit the needs of many industries.
• Commercial invoice: This invoice is the same as the standard invoice but it is used internationally. It includes the details of the business transaction such as the weight and the packaging of the package for the abroad sales purpose.
• Pro forma invoice: This type of invoice includes the estimated hour and cost to complete a project. The information required doesn't have to be exact.

• Debit invoice: This is used for the additional hours or amount that need to be modified on the project plan.
• Credit invoice: This invoice is issued when a business wants to give a discount/refund or to correct an error for its clients.
• Recurring invoice: We use recurring invoices when a client buys some products or services many times, and you have to send them the same invoice.
• E-invoice: This is a new specific type of invoice that can be sent electronically. Nowadays, invoicing software can help you do this at a glance.

The time to make an invoice comes once the sale or service is completed.

👉 For a sale of goods: the invoice is issued at the time the buyer and seller have jointly agreed on the order. In some cases, the invoice is issued at the time of delivery of the goods, which may differ from the date of the sale.

👉 For services: the invoice is issued when the service is performed. For long services, progress invoices can be issued to stagger payments, and thus the business doesn't wait until the service is completed to invoice.

In addition to the invoice reference on the header, here are all the mandatory aspects to include:

The identity of the supplier

• the company name or the name of the supplier,
• the address,
• the place of registration,
• the VAT identification number, if applicable.

The identity of the buyer

• the company name or the name of the buyer,
• the address,
• The reference to the invoice
• the invoicing number - it must be unique,
• the date of the invoice.

The description of goods or services invoiced

• their price or rate,
• the unit amount,
• the quantity of items,
• the date of delivery or the date of completion of the service.

The amount of the invoice

• the total amount of the goods or services invoiced,
• the applicable tax rate,
• the total amount including sales tax,
• any mentions relative to the applicability or not of other taxes or fees,
• possible price increases or discounts,
• the payment terms.

Mentioning payment terms are one of the most important elements of an invoice. It includes the details about the payment such as:

• the due date for payment,
• the penalties applicable in case of delay,
• the discount conditions if it is a question of an anticipated payment

You can also meet some abbreviations such as CIA (Cash In Advance), EOM (End Of Month), Net 30, etc. so make sure that you know them!

Follow these 3 easy steps to submit an invoice!

After creating your invoice, you can proceed to the approval section. This process is used to check the admissibility of your invoices, so that only "approved" invoices are admitted to the following processes within your company: invoice processing in accounting and payment initiation.

The admissibility check consists of verifying whether an invoice is addressed to your company and whether it was received as a result of an order, or a contract.

Once the invoice is approved by the accounts payable representative, the supplier will receive a confirmation mail that the invoice summary is ready to be viewed. Then they will use the supplier portal website to view the invoice summary.

At this step, they can verify if there is an error or incorrect information. If so, they still can modify it and make another demand for invoice submission.

Once everything is done correctly, the supplier can send the invoice to the client. When the client receives it, they can record it in their book. At this moment, the invoice will become a bill that they have to pay.

Did you know that your invoices can become real marketing tools?

Invoices are one of the most important financial documents for a company, and these documents are carefully read by your customers. Take advantage of this opportunity to transform it into a tool of your marketing strategy, either via the email sending the invoice or on the invoice itself.

• At the end of your invoice, you can remind your customers of the products you sell (in order to make a cross-sell via a product each month), or offer promotions on higher-end products (upsell), special packs, and accessories…
  
  
• You can include a message in your invoice indicating a discount for future orders if it is placed before next month to encourage customers to recommend it sooner.
  
  
• Most billing software allows you to customize your invoice with a few clicks. These personalization options can be a way to communicate about a brand change, a company takeover, annual vacation closures, new payment methods, a new commercial policy, price changes, a move, an inauguration, a trade show… Take advantage of this opportunity to personalize your invoices, and give them a real "soul", just like other contact channels with your customers.
  
  
• Your invoice can be used to retrieve information, for example, you can mention a contest to get emails, and contact information of people in the company.
  
  
• If the people paying or forwarding the invoice are the end customers, you can use the invoice (sending email & mentions on the invoice) to collect customer reviews (or ask them to post a review, to like a Facebook page...) in exchange for a coupon present on the invoice.

While many companies still operate on a 30-day payment cycle, this is not mandatory. Some SMEs now require invoices to be paid within seven business days. And keep an eye out for customers who fail to meet payment deadlines. Controlling outstanding payments is an important part of your company, so nip any bad behavior in the bud.

“Using invoicing software is too expensive”

FALSE!

Good invoicing software or an invoice generator adapted to the needs of entrepreneurs exist (and are sometimes even free), and bring several advantages:

• An invoice software helps to control the deadlines in parallel with the production. The invoice must be sent at the time of the realization of the service or at the time of the delivery of the good.
  
  
• By automating a part of the process, software strongly limits the risks of error (involving the production of a credit note or credit invoice). It is a good way to save precious time.
  
  
• The possibility of consulting invoices offers a valuable analytical vision. Hence the interest in using a solution capable not only of editing an invoice but also of listing and archiving it in a relevant manner.

You can check out free invoice software if you are a small business or an entrepreneur. There is a wide range of free online invoice generators with many features on the market nowadays. Some of them use Paypal, Skrill, or Google Pay as a payment transfer tool which is very convenient.
