When ERP Falls Short: Adding a Third-Party AP Automation & Payments Platform

Written by Rebekah McCabe | Sep 9, 2026, 8:14:20 PM

There are a number of reasons businesses decide to upgrade their ERP, but we are seeing customers increasingly prioritize functionality for Accounts Payable (AP) and finding automation tools that can reduce the load on their AP teams. And part of that is determining where the ERP functionality ends and where a specialized solution is needed to achieve more complex goals.

Companies both in need of an ERP upgrade and those already on a modern ERP should take the time to consider whether they will require an external solution in addition to their ERP. 

An All-Inclusive ERP Selection

For many, the logical step is to include advanced AP and payments requirements within their initial ERP selection. During the needs analysis phase, companies sometimes uncover more complicated requirements that go beyond the scope of most ERPs, such as greater fraud mitigation, advanced invoice automation, or mass payment processing. When these requirements are essential to business as usual, there is a case to be made for a specialized, third-party solution.

Depending on the vendor or implementation partner a business selects, the recommended solution will vary. Some vendors have strategic alliances in which they have embedded solutions directly within their platform. This enables customers to “flip a switch” when the more advanced capabilities are needed. Others have partnerships and have developed pre-built integrations with Independent Software Vendors (ISVs) who specialize in certain functionality or industry needs.

We recommend leaning on your partner or vendor during this time for best practices and recommendations. Fortunately, this process does not need to be as vast as the initial ERP selection, and by relying on the experts, you can narrow your shortlist of solutions much faster based on industry, size, needs, and core ERP solution.

Remember, you must include these needs in your communications with potential vendors and implementation partners because it will enable them to include the right solutions in final demos.

Third-Party Solution Selection

Alternatively, a business may determine their core ERP does not need to be replaced, but that they do need a new, more robust AP and payments platform. In this scenario, it is important to identify and document exactly why you need an external or outsourced solution.

The emergence of manual processes or struggles related to late payments and strained vendor relationships, even after migrating to a modern ERP, can be signs an organization needs a more advanced solution. More specifically, if those obstacles are preventing the business from delivering to customers or are holding them back from future growth.

Examples Where ERP Falls Short

There are a number of “red flags” associated with the need to pursue a third-party AP automation and payments platform solution to supplement ERP functionality. While ERPs are great systems of record, they are not developed for capturing high volumes of invoices, managing international multi-currency payments, or managing the relationships between suppliers.

High Volume of Invoices – A company processing a significant number of invoices over the typical threshold for an ERP can overwhelm the system. Ultimately, this results in manual processes to enter data and make payments.

Payment Method Diversity – Some operations require a system to manage ACH, virtual card cash-back rebates, international wires, checks, and other payment methods. ERPs can struggle to effectively account for and mix various payment methods without a third-party tool.

Global Payment Needs – A company with a global scope that must comply with various tax compliance laws, banking rules, and juggle multiple currencies often faces issues within their ERP that require a third-party solution.

Supplier Management – ERP alone does not offer a way for vendors to enter a self-service portal to interact with a business, pay invoices, or track statuses. In the modern age, vendors can become frustrated by outdated processes, which can indicate a need for a more advanced AP and payments platform.

Types of Financial AP Solutions & Payments Platforms

There are a number of solutions on the market that offer different services depending on your business’s needs and priorities.

What is a Payments Platform?

A payments platform, simply put, is a digital solution enabling organizations to “move, track, and manage money.” It simplifies the process of managing money because it removes traditionally manual processes around cash and checks. The data is synchronized to the business’s ERP for greater organization and maintenance of the general ledger.

“Payments automation is the use of software, validated banking data, and managed service to execute outbound B2B payments (ACH, virtual card, check, and wire) from a single approval workflow, then post the results back to your ERP. It's the money-out leg of accounts payable, separated from invoice handling and treated as its own discipline. AP automation runs the invoice; payments automation runs the disbursement” (corpay.com).

Corpay, a global provider of payments and AP automation, is one of the foremost vendors in the space, developing specialized solutions to help businesses manage and pay for business expenses in a simple, controlled manner.
