    For any business the most important thing to do post sale execution is to document that through an invoice. Invoice might sound simple but is one of the most important pieces in documentation as it not only helps the business accounting run smoothly but also has a legal standing in the court of law if the need arises. The options we have to create an invoice range from doing it manually from scratch on a word doc to using a professional tool potentially free on the internet. Both have their pros and cons and let’s take a quick look at pros and cons of manual invoicing.

    Immediate Error Detection: Manual invoice creation allows for the immediate identification of errors, inconsistencies, or irregularities.

    Handling Unique Cases: It enables efficient management of exceptional situations, providing flexibility to handle unique invoicing cases quickly.

    Cost-Free: There are no associated software or subscription costs, making it a cost-effective solution.


    Time-Consuming: Creating invoices manually is time-intensive, especially as the business grows, leading to increased workload and inefficiency.

    Risk of Human Error: There is a high likelihood of mistakes, which can affect the accuracy and reliability of invoices.

    Limited Visibility and Tracking: Manual invoicing can result in incomplete visibility and tracking, hindering the ability to make informed, critical business decisions.

    Let's also look at the pros and cons of using an online invoicing tool


    Efficiency and Speed: Online invoicing tools streamline the invoicing process, significantly reducing the time required to create and send invoices.

    Accuracy: Automated calculations and standardized templates minimize the risk of human error, ensuring more accurate invoices.

    Enhanced Visibility and Tracking: These tools provide comprehensive tracking and reporting features, offering better visibility into invoicing and payment statuses, aiding in informed decision-making.

    Scalability: Online tools can easily scale with the growth of your business, handling increased invoicing volume without additional manual effort.

    Integration with Other Systems: Many online invoicing tools integrate seamlessly with accounting software, payment gateways, and CRM systems, enhancing overall business efficiency.


    Dependency on Technology: Reliance on internet connectivity and software functionality means potential downtime or technical issues could disrupt the invoicing process.

    Learning Curve: Adopting a new tool requires time and effort to learn and integrate into existing processes, which can be a temporary hindrance.

    Data Security: Storing sensitive financial information online poses potential security risks, making it crucial to ensure robust data protection measures are in place.

    Let’s use another example where you are the client. Imagine you're choosing between two advertising agencies. On one side, there's Emily, who runs a tight ship at AWT Advertising agency. Her office is a beacon of efficiency—every project is planned to a T, and her invoices? They're the epitome of accuracy and give you the convenience of being able to pay them online.

    Next door, we have Alex from BCDO Agency. Alex is the king of creativity, always thinking outside the box. However, his invoices tell a different story: built manually, inconsistent design across them, and sometimes missing crucial details and, yes, sometimes his office is late to create them too.

    Who would you rather partner with? It’s no surprise that Emily’s agency gets more clients. This little tale highlights an important business truth: efficient billing processes are crucial for keeping that cash flowing and maintaining solid professional relationships. And your invoice is arguably the most critical piece in that billing process.

    An invoice is not just a request for payment; it's a reflection of your brand and professionalism. In the following article we will cover everything you need to know about invoicing processes and invoice templates, from their essential elements to customizing them to suit your industry-specific needs.

    What are the basics of an invoice template?

    What would make Emily’s invoice stand above Alex’s? It’s probably because Emily’s is more comprehensive and easy to navigate. By definition, an invoice is a formal request for payment issued by a seller to the buyer after goods or services have been delivered. It details the transaction and prompts payment, playing a critical role in accounting and payments for both small and large businesses.

    While you can add many custom elements to an invoice, there are some that are essential:

    Date: The date the invoice was issued.

    Invoice Number: A unique identifier for record-keeping.

    Seller and Buyer Contact Details: Names, addresses, and contact information.

    Description of Goods or Services: Detailed list of what the buyer is being charged for.

    Prices and Quantities: Itemized costs and quantities.

    Total Amount Due: Clearly stated, including taxes and discounts.

    Payment Terms: Due date and accepted payment methods.

    What are the legal requirements for invoicing in North America?

    Emily’s agency is more likely to be out of legal troubles related to billing or client management as she ensures that her invoices are comprehensive and cover all legal aspects required in the regions she operates. Before we move into any more details it’s important that we cover the legal aspects involved in an invoice.

    In North America, legal requirements for invoices can vary by country and by state or province. Here’s a general overview for the U.S. and Canada:

    United States

    In the U.S., invoices are not heavily regulated at the federal level, but they must comply with the general rules of contracts and transactions. An invoice should include: The seller's and buyer's name and address A description of the goods or services provided The date of the invoice and the date goods or services were supplied The amount charged and terms of payment Sales tax, if applicable If a business is involved in certain regulated activities or deals with government contracts, specific requirements may apply.


    In Canada, the requirements for invoices are more specific, especially because of the Goods and Services Tax (GST), Harmonized Sales Tax (HST), and Provincial Sales Tax (PST). Canadian invoices must include: A clear breakdown of goods or services provided The date of the invoice and the date of supply Information about the supplier including business name, address, and, if applicable, the GST/HST registration number The total amount paid or payable A breakdown of taxes (GST/HST and PST) if applicable For businesses registered for GST/HST, detailed invoices are criticall for tax purposes.

    What are the different types of Invoice Templates?

    While Emily and Alex both run advertising agencies they may have specific requirements for their invoices for specific situations so they should be able to adapt their invoices freely to suit their needs. There are several types of invoice templates, each serving a different purpose:

    is owed for goods or services provided.
