How to Integrate OFAC Screening with Your AP Workflow

Sanctions screening has become a standard expectation for modern accounts payable teams. As government watchlists evolve and vendor data changes over time, organizations are responsible for ensuring that outgoing payments comply with current regulations. 

An often-missed – but crucial - step for AP teams is to screen all vendors, businesses or individuals, through The Office for Assets Control (OFAC) sanctions list. (Read why it’s important here)

For AP teams, this responsibility sits at a critical intersection: payments must move efficiently, but controls must remain strong. Automated sanctions screening helps balance both, especially when it is built directly into the accounts payable workflow.

OFAC screening should be integrated into the workflow of your company's accounts payable (AP) department and performed on a regular basis. Once is not enough, as the OFAC list is always being updated. If you do mistakenly do business with an entity on the OFAC list, your organization could face large fines or legal penalties.

This article explores how sanctions screening fits into AP processes, why automation matters, and what effective screening looks like in practice.

When Should You Perform OFAC Screening?

AP staff need to be educated on the importance of OFAC screening and have access to tools and resources to perform effective OFAC checks. This may include training on how to use OFAC screening software and what to look for when conducting OFAC checks.

Vendor Onboarding

OFAC screening should be part of your process when onboarding a vendor. It’s best to check the vendor name against OFAC records before ever entering them into your ERP or accounting system.

Upon Invoice Receipt

You may want to verify status when an invoice is received. This can identify any potential red flags and prevent transactions with individuals or entities that are subject to OFAC sanctions.

Before Issuing Payment

Another approach is to implement a system that automatically checks OFAC sanctions before a payment is made, and even automatically withholds payment from going through if an issue is discovered.

Routine Audits

AP departments can incorporate OFAC screening into their workflow by conducting regular audits and reviews. This can help to identify any transactions that may have been missed during the initial screening process and ensure that the company is in compliance with OFAC regulations.

What’s the Best Way to Perform OFAC Checks?

AP teams can screen vendors against the OFAC list in three ways:

1. Manually: AP staff can research a business or individual on the US Treasury’s OFAC Sanctions Search List.
2. Use a third-party: You can outsource OFAC screening by contracting with a third-party provider.
3. Software: There are software solutions that automate OFAC checks and integrate partially or fully with your ERP or accounting system.

Why manual screening falls short

Many organizations still rely on manual or ad hoc screening processes. These approaches often include spreadsheet checks, external websites, or one-time reviews performed during vendor onboarding.

While well-intentioned, manual screening creates gaps:

• Vendors may only be screened once, not continuously

• Checks may be skipped during busy payment cycles

• Results may not be documented consistently

• Different teams may follow different processes

As invoice volumes grow and AP teams become leaner, these gaps increase both compliance risk and operational stress.

Where sanctions screening fits in the AP workflow

Sanctions screening is most effective when it aligns with natural moments in the accounts payable process, rather than existing as a separate task.

Common workflow points include:

• Vendor creation and updates
  When a vendor is added or modified, screening helps ensure the record is valid before payments are allowed.
• Payment preparation
  Before payments are finalized, screening confirms that vendors remain clear as lists and regulations change.
• Ongoing vendor maintenance
  Vendor data is not static. Continuous screening helps AP teams avoid relying on outdated assumptions.

By embedding screening into these moments, compliance becomes part of normal operations — not an interruption.

Outsourcing the process may validate after you’ve already paid a vendor, and this can cause serious hassles if issues are discovered. Some outsourcing services will also require you to do an initial validation before you send them data.

The most reliable way is to find an integrated software solution where the results are visible in your accounting system.

The benefits of automated sanctions screening

Automated sanctions screening helps AP teams by:

• Running checks consistently without manual effort

• Reducing last-minute payment holds

• Supporting audit readiness with clear records

• Allowing AP staff to stay focused on core work

Rather than slowing payments down, automation often speeds the process by identifying issues earlier.

What effective sanctions screening looks like

When sanctions screening is working well, AP teams experience:

• Screening that happens automatically at defined points

• Clear visibility when exceptions require review

• Consistent application across vendors and entities

• Confidence that payments meet compliance standards

The goal is to remove complexity and focus on security and reliability.

Building compliance into everyday AP work

Sanctions screening does not need to be a separate system or a burdensome step. When it is designed as part of the accounts payable workflow, it becomes a quiet control that protects the organization while keeping payments moving.

Forward thinking AP teams increasingly look for approaches that embed compliance into everyday processes. This approach creates consistency, reduces risk, and supporsts long-term operational health.
