Accounts Payable Automation Software A Practical Guide to Choosing the Right Fit

The reason why Accounts Payable remains a major issue for many finance teams

If you ask any finance manager about the most time-consuming processes in their department, they’ll probably mention accounts payable. Invoices come in a variety of formats including PDFs, scanned paper documents and emails with attachments hiding under three or even more responses.

Therefore, someone needs to enter all the information, compare it with the purchase order, find the person responsible for approval who happens to be on vacation and make sure the payment is sent as quickly as possible in order to avoid endless reminders form the supplier.

There are no difficulties in any of these tasks. However, when done manually, it proves to require too much effort and is also expensive, as it involves too many mistakes.

This guide will provide the reader with all necessary information concerning the working principles of Accounts Payable automation software, the types of all the potentially useful tools, as well as the appropriate method to choose from all the existing options.

What AP automation software actually does

AP automation software essentially involves an account payable process that includes invoice receipt, data capturing, matching, approval, and payments. The majority of the technology does a combination of functions as outlined:

  • Invoice data capturing and extraction using either OCR technology or artificial intelligence so that invoice information does not have to be keyed in.
  • Automated matching, commonly two-way or three-way matching as per the purchase orders and goods received note so that mismatches can be identified before payment.
  • Approval routing workflow that provides invoice approval automatically based on amount, department, and the vendor involved, and switches to escalation for invoices delayed with approval.
  • Vendor management tools including self-service portals used by vendors to check the status of their invoices without having to contact the company.
  • Payment automation to carry out the payments using ACH, electronically, virtual cards, or check technologies that facilitate payments that can include discounts for early payments.
  • Reporting and audit trail functions that allow executives access cycle time, liabilities, and compliance documents.

Not all of these functions are available with every application therefore it is important to compare the applications before selecting one.

The Reason for Companies Using AP Invoice Automation

There are various advantages that firms benefit from by implementing AP invoice automation, and here are some:

Reduces mistakes and redoing. The traditional process of entering data manually can lead to issues such as mismatched prices, duplicate payments, or vendor’s wrong details. Automating data acquisition and matching helps to avoid such mistakes in advance.

Less time spent on processing invoices. It takes an invoice that needs to be routed through email approvals, processing it for a week. Nowadays, automation can help to finish the process in a day or two.

Better controls guarantee compliance. The automated matching of three documents and hierarchy of approvals minimize the chances of a duplicate or fraudulent invoice appearing.

Improved vendor relationships. Making the payment on time is important for suppliers.

Transparency of finance. AP data being stored in the system instead of different spreadsheets makes it easy for the finance director to plan its outgoing cash more accurately.

Different Types of AP Automation Software.

AP automation tools are available in a variety of shapes and sizes, and knowing each type helps you determine which ones are suitable for your company.

A standalone AP automation software is a type of platform that specializes in any or all of the three aspects of the AP process: invoice capture, approval, and payment. It usually provides excellent solutions for small and medium enterprises because they don’t require a complete renewal of their financial management systems. Bill.com and Stampli are examples of solutions falling into this category.

While ERP modules are integrated in ERP solutions, they only provide limited options not worth attention. Different companies prefer using different solutions, depending on what system they are already using. Different ERP systems could be mentioned here, including SAP and Oracle NetSuite.

Procure-to-pay (P2P) suits provide additional features that extend beyond AP. They involve sourcing, issuing purchase orders, and managing suppliers, as invoice processing is just one of the stages of procurement processes. Products like Coupa, Zycus, and TYASuite are giants in this field, and they offer useful options for companies looking for solutions connecting procurement with finance on one platform.

The AI-first invoice processing system uses a high ratio of machine learning to enable completely touchless invoice processing. Its goal is to eliminate human intervention in normal invoice processing and only send true exceptions to the person for processing.

Is there a winner among the systems discussed? The answer will depend on variables, such as the volume of invoices, type of ERP used, geographical factors, and budgets available.

Some interesting systems that are worth mentioning:

  • TYASuite has been positioned appropriately in the C2P (cloud-based procure-to-pay) space as it offers an integrated system comprising accounts payable automation alongside vendor workflows and purchase order management. The tool has received acclaim from middle market and enterprise customers who seek integrated systems rather than independent tools for invoice management.
  • Bill.com provides the tool for automating accounts payable (AP) and accounts receivable (AR) processes, being the handy tool for small and medium companies that integrate well with the accounting systems like QuickBooks and Xero.
  • Stampli established reasonable approach to invoice approvals in a way that it allows for teamwork because all communication concerning invoices, which takes place while processing an invoice, is attached to the invoice itself.
  • Tipalti is useful for companies that have many foreign vendor payments due to its focus on compliance and multi-currency payouts.
  • Coupa and Zycus are full procure-to-pay solutions, being perfect for significant companies that would like to keep control over the whole procure-to-pay process.
  • SAP Ariba and Oracle Procurement Cloud offer organizations already using these ERPs leverage the current integration to exceed the demand for a specialized tool.

In this case, it is impossible to unequivocally say which product is the best as the requirements of a company handling invoices of around 200 per month differ significantly from those of the company processing 50,000 invoices.

Assessing AP Automation Software for Business Needs

Instead of looking at lists of capabilities, focus on specific questions, such as:

1. What is your overall invoice volume and complexity of approval process? Companies with fewer approvers require simpler software packages while large corporations with many layers of sign-off need significantly more advanced solutions.

2. What is your setup for current accounting / ERP software? Approaches that offer pre-built integrations will save a lot of time. If your finances are already being managed within SAP or similar, this will play an important role in narrowing down your options.

3. Do you need a procurement module or only AP capabilities? If you already have a solution for managing purchase orders and vendor searches, going with a simpler AP-focused tool might work better compared to a full way of doing procure-to-pay.

4. How many currencies do your vendors use? Being able to deal with several currencies and tax regimes is essential if you’re paying vendors from different countries as opposed to the case when all transactions are happening domestically.

5. How long is the feasible implementation timeline? Some platforms become live in a few weeks; enterprise P2P systems often take months with change management making a real impact.

6. What does the pricing model actually cost at your invoice volume? Per-invoice price systems do appear cheap at low volumes, but they become quickly expensive as the business expands and it is crucial to model this before agreeing to anything.

Errors to Avoid in AP Automation Adoption

Repeatedly, there are certain common problems when it comes to poorly thought out implementations of automatic policy automation: selecting the solution based on a framework demonstration rather than real invoice pilot usage, not taking necessary steps to ensure that supplier information is efficiently delivered before going live, skipping necessary work on map approval matrix (thus creating disruption similar to traditional manual appraisal), and failing to instruct all the release approvers in other departments and not involved in finance.

Future Trends of AP Automation

A new influx of AP automation solutions is going to be characterized by fully AI-driven processing - processing invoices with no human intervention except the case of exception management. It is normal now to expect predictive analytics for forecasting cash flow, payment systems that enable instant payment process, embedded fraud prevention, among other things. While choosing the tools nowadays, one should not only ask about current functionality, but also get interested in the vendor's investments in further developments.

Conclusion

Software for automating invoice payments is not a standard term; rather, it covers everything from simple invoice applications to comprehensive procurement systems. Companies that benefit the most from the software are usually the ones who begin by accurately estimating their invoice volume, existing system capabilities, and complexities related to approval of invoices. In any case, whether they opt for an independent tool, ERP module, or P2P system, the idea is the same: fewer manual processes and a financial department spending more time making key decisions than dealing with data entry.
