Other popular automated invoicing software

The above list is not exhaustive. The market for invoice automation is growing rapidly. 

While the above are our top picks for invoice processing software, there is no such thing as the best solution.

We want to help you pick the most suitable one based on your needs. If you haven’t found the right invoicing tool for you, here are 10 additional invoice processing software/tools worth looking into:

Need for automating invoice processing using software solutions

Your accounts payable team processes many invoices daily, ensuring funds are disbursed correctly to vendors, business partners, customers, and sometimes employees. Processing an invoice can take days when done manually. 

An AP expert has to conduct three-way matching checks. This is to check and validate a match of details on a vendor’s purchase order, the supplier's invoice, and the delivery receipt before the payment is processed and an invoice is considered paid.

This 3-way payable process looks simple but has many potential obstacles. With invoice processing automation, the time it takes for invoice check validation and payment processing is dramatically reduced. 

These solutions can conduct matching processes, route the invoice for approval, prepare necessary payment information, and save your AP team a lot of time.

Invoice automation is essential for your AP team, finance leadership, and CFOs to improve cash flow visibility and control, mitigate risks, reduce costs, and boost profitability.

How to choose the best invoice processing software solution 

Choosing the right invoicing software today has become more challenging than ever.

Start by trying a few invoice processing tools and work up from there. Sign up for free demos and show up. When you evaluate your options, differentiate the tools based on your team’s needs.

Leverage third-party software review tools like G2, TrustRadius, Gartner, and community platforms like Reddit and Quora to understand user experience.

Here are a few things to consider when choosing an invoicing software:

Features of the invoice automation software

This one is a no-brainer. While most software these days have similar functionalities, the feature differentiator is essential when picking the right software.

When it comes to invoice processing, look for features that can reduce your team's manual tasks, such as automated invoice sending, invoice matching and reconciliation, approval workflows, and automated data entry.

For a good vendor relationship, consider the tool's mobile functionality and the usability of the web interface to make invoice processing smooth for vendors.

Cost of Ownership

While many invoice processing tools are in the market, few allow you to test their capabilities, and even fewer have transparent pricing. Many of these tools don’t just focus on invoice processing or AP automation and only provide a custom quote.

While it is easy to be lured by the big legacy names, evaluating the tools based on their cost of ownership and your budget is essential. 

The cost of ownership doesn’t just end at the tool's price. It also includes maintenance, annual fees, implementation costs, and the potential cost of scaling. This will save you any later expensive surprises in the future.

Understand the subscription model and pricing structure—it’s usually based on transaction volume, the number of users/employees, or a flat licensing fee.

Implementation and ease-of-use

Many financial and accounting tools have a long learning curve, and employees often resist adopting new technologies.

To avoid this, evaluate the tools' usability and check the efficiency of customer support—not just at the beginning but also later. Assess the tool's complexity and check in with your AP or finance team on the level of automation required.

Adopting a simple invoice processing tool takes at least a few days or weeks. If you want a complete AP automation solution, onboarding can take a few weeks or months. The times vary depending on your organization's size, the tool's complexity, and the integration required.

Prioritize tools that are no-code or require little to no technical expertise. Your finance team shouldn’t have to spend days or weeks training your invoice processing tool with multiple invoices or POs only to find inaccurate results. 

Why Enterprises Are Learning To Love Nanonets’ Automation

Nanonets has raised $29 million in a Series B round that will support the growth of the machine learning and automation specialist

Automation and level of integration

Your invoicing automation software should be compatible with your other tools, like ERP software, and show deep integration penetration—from data sources like emails and Slack to reconciliation and accounting.

Integration is the key to perfect implementation.

Prioritize solutions that offer flexibility, like custom rule-based approval workflows and OCR-powered data extraction. 

Assess the pre-built integration capabilities of the invoice-processing software to minimize training and face issues later.

Payment capabilities

Consider the invoicing tool's global payment capabilities if you are a global company or manage vendors outside your country.

Making global payments can be costly if your invoicing software doesn’t support the said currencies. The software should be able to reconcile domestic and international payments easily.

Accuracy and speed

Automation aims to increase task accuracy and efficiency and ensure no employee effort or time is wasted on repetitive manual data entry.

Invoice capture accuracy and speed sync are essential in evaluating invoice processing tools.

Final word

Invoicing is a basic need of all businesses. While a few still choose to do it manually with freely available online templates, manual data entry, and payment processing, many others have automated it partially with different invoice processing tools.

Before investing in automation, whether invoicing tools or fully integrated AP automation software, it’s important to evaluate everything and not rush into purchasing new software.
