Why AP Delays Aren’t Just About Volume (And Where Time Actually Gets Lost)

Many teams assume accounts payable delays are caused by invoice volume.

But in most cases, volume isn’t the issue.

The real slowdowns tend to come from small gaps in the process—especially in how invoices move between purchasing, receiving, and finance.

These gaps are easy to overlook because the process is technically working. Invoices are getting processed. Payments are going out. But behind the scenes, time is being lost at key points along the way.

Where Time Actually Gets Lost in AP

If you break down the AP workflow, delays tend to show up in a few consistent places:

1. Approvals don’t have clear ownership

Invoices often sit waiting, and not because someone is unavailable, but because it’s unclear who needs to take action next. This is especially common when approvals span multiple teams or systems

2. Exceptions fall outside the main workflow

When an invoice doesn’t match a PO or has missing information, it often gets pulled out of the process and handled separately. That usually means email follow-ups, side conversations, or manual tracking.

Over time, these “one-off” exceptions become a meaningful source of delay.

3. Information isn’t aligned across teams

AP depends on accurate data from purchasing and receiving. When that information isn’t consistent or easy to access, finance teams end up chasing answers instead of processing invoices.

Why These Issues Are Hard to Fix

What makes these delays challenging is that they’re not always visible.

Most systems will show you that an invoice is in process, but not:

• How long it’s been sitting at a specific step
• Why it hasn’t moved forward
• Where handoffs between teams are breaking down

So teams compensate manually:

• Following up over email
• Keeping separate trackers
• Relying on internal knowledge to push things through

That works in the short term, but it doesn’t scale.

How to Spot Gaps in Your Own Process

Instead of focusing on volume, it’s more useful to look at how work is actually flowing.

A few quick ways to assess your process:

• Look at aging by step, not just overall cycle time
  Where are invoices sitting the longest: approvals, exception handling, or matching?
• Track how exceptions are resolved
  If resolution happens outside your core workflow, that’s a signal the process isn’t fully connected.
• Ask how teams get answers
  If AP frequently has to reach out to purchasing or receiving to move an invoice forward, there’s likely a visibility gap.
• Check for parallel systems
  Spreadsheets, email threads, or side trackers often indicate the main process isn’t capturing everything it needs to.
