What is Billing Software?

Billing and invoicing software provides a range of functionality that is critical to collecting revenue, the end goal for all successful businesses. These billing solutions may vary in breadth of capabilities or target different professions and business sizes, but each offers the ability to streamline and automate the invoice and billing workflow. Collecting payments from customers can be a struggle, so improving the billing process and increasing the ease of collection to help ensure timely payments is always beneficial. Billing software allows users to build an invoice that will eventually be sent to a customer to collect payment. Often, billing solutions offer pre-built invoice templates for users who are looking for basic, straightforward invoice layouts. They may also offer an invoice creator for companies interested in building out custom invoices, which can be branded and personalized to fit a company’s criteria. Once the invoice is built, users may choose to print and mail the invoice; however, online invoicing is more widely used in today’s business world. Users can set invoice reminders that alert the customer that a payment due date is approaching, making sure that they are aware of what they owe and helping get ahead of the collection process. Customers can reply to payment requests on the spot, either through a payment gateway or directly through the invoice, with a variety of different payment methods. This includes credit card or other forms of electronic payments, which can be set up to recur monthly or on a subscription basis. For project- and service-based companies, time tracking functionality is offered to record hours worked and to bill for those hours accordingly. Hourly rates can be adjusted based on the project or employee; expenses associated with said project and employee can be documented as well. Once that information is recorded, invoices can be sent and payments collected. Billing fits into the overall accounting software ecosystem, and is just one aspect of financial management. These solutions generally integrate with other accounting, ERP, or CRM tools for greater insights and transparency into business processes. As a business grows its customer base, billing software provides one central location for all invoice and collection needs, allowing businesses to stay organized and on top of their finances and overall revenue management.

Why Use Billing Software?

The reasons for using billing software appear simple at first; in actuality, billing solutions provide a breadth of advantages for accounting departments and businesses. The business problems that billing and invoice software solve range from basic organization of invoices, to automated collection, simpler record keeping and tracking, and even improved customer relations. Improved Organization – When a business has multiple customers, it can be challenging to keep track of all invoices. That’s where billing and invoice software comes in to play. Billing solutions provide one central location for all invoices, so accountants are never scrambling to find documentation surrounding paid or unpaid bills. This billing hub ensures that businesses can better keep track of all customers and where they stand with their payments. This helps businesses improve customer relationships through the ability to routinely follow up and request payments when they are due. It also helps accounts receivable departments track all incoming finances for better overall accounting. If a business is not using a payment management system, such as a billing and invoicing software, then accounting departments will be spending hours just attempting to organize invoices, let alone make sense of them. Billing Automation – Before billing automation, businesses would usually have to create invoices in a basic document creation software (such as Microsoft Word), print the invoice, and mail it to a customer. That customer would usually have to write a check and mail it back to the business. However, billing and invoice software allows users to automate this process from start to finish. Users can create invoices online and send them to customers instantly via email or a client portal. This online invoicing allows customers to then pay instantly through the application, and the business receives its money instantly. This automation saves businesses time and effort, and allows for increased tracking capabilities. The biggest business problem being solved with billing automation is attempting to eliminate late or missed payments by customers. By doing so, businesses can collect money on time and help improve revenue growth month over month, quarter over quarter, and year over year for increased valuation. Easier Record Keeping and Tracking – By integrating billing and invoice software with accounting software, users can easily keep track of end-to-end accounting records. Billing software specifically tracks all expenses and records from invoice creation to the payment by the customer. This provides more transparency for businesses and allows for accurate accounting through the end of the billing cycle. These solutions also provide insights into the financial standing of customers, which is a huge benefit when customers are set up for subscription billing. Improved Customer Relations – Sending prompt alerts for customers with outstanding balances is not only a good way to ensure timely payments; it is also a way to reach out and build customer relationships. One might believe that these notifications are agitating, but in reality, customers want to pay on time, so being proactive in this scenario is helpful. Additionally, client portals offer a way for accountants on both sides of the invoice to quickly converse as well as a way for companies to provide quick customer service. By staying on top of billing inquiries, businesses can maintain positive relationships with customers and receive timely payments.

Who Uses Billing Software?

Billing and invoicing software is used by a number of different employees within an organization. The main role that utilizes billing solutions are accountants. An accountant is a broad title, but often in-house accountants are in charge of accounts payable and accounts receivable, meaning they are required to collect payments from customers. Those specifically tasked with collection may be considered billing coordinators or collection specialists. Some larger enterprises may employ billing analysts to help forecast and budget based on billing and revenue history. For professional services, a project manager may be in charge of invoicing customers. This is done based on specific projects, how much time was spent on a project, and the hourly cost for the customer. The project manager may be tasked with working with the customer and ensuring timely payments come in, regardless of the progress of the project. In the health care world, medical billers and coders are in charge of collected outstanding payments. This is a much more complex and regulated form of billing collection due to insurance claims and the complications included with that side of the business. For smaller, private practices, the doctor or the office administrator may be in charge of filing insurance claims and collecting payments. Other practices may outsource to medical billing services. Small-business owners may be the ones in charge of collecting payments if the company is not large enough to have its own accounting team. Often, these users will have a small-business accounting tool that offers online invoicing and invoice templates. These solutions are built for those that do not have the expertise of accountants or collection specialists.
