Digital Banking Solutions for Banks and Credit Unions

Upgrade ACH Blocks and Filters with ACH Positive Pay

Home » Blog » Product » Upgrade ACH Blocks and Filters with ACH Positive Pay

Discover how banks and credit unions can ditch manual processes and clunky workflows by switching from automated clearing house (ACH) blocks and filters to a smarter, smoother ACH Positive Pay solution with Alkami.

Picture this: a well-meaning business client calls your operations team at 4:45 p.m. on a Friday. They just noticed an unauthorized commercial ACH debit hit their account—and now they want to know how it happened, how to stop it, and how it got past the blocks they swore were set up.

Cue the collective sigh.

For banks and credit unions, protecting business accounts from fraudulent or unauthorized ACH transactions has traditionally meant relying on ACH blocks and filters. While these tools have served a purpose, let’s be honest—they’re starting to show their age. The more volume and complexity you manage, the more these band-aid solutions start to feel like a game of digital dodgeball.

Enter ACH Positive Pay with Alkami—a smarter, cleaner, and more user-friendly way to manage ACH fraud prevention that brings efficiency and consistency to your operations and control back to your business clients.

 ACH blocks and filters causing manual stress vs ACH Positive Pay efficiency

What Are ACH Blocks and Filters Anyway?

ACH blocks and filters are legacy fraud prevention tools used to stop unauthorized electronic withdrawals from business accounts. Think of ACH blocks and filters as the bouncers of your ACH club—keeping unwanted transactions from entering the party.

  • Blocks completely stop ACH debits from hitting an account.
  • Filters are more nuanced—they let some transactions through based on pre-approved criteria, such as originator ID.

While these tools work, managing the addition and removal of ACH blocks and filters usually falls squarely on your operations team. It’s a manual, time-consuming task that often requires inputting filters one by one, responding to exceptions, and dealing with panicked calls from clients when something goes wrong.

Now, multiply that by dozens—or hundreds—of business accounts. You see where we’re going…

The Case for ACH Positive Pay

ACH Positive Pay takes the foundational concepts behind ACH blocks and filters and levels it up. It replaces reactive, fragmented workflows with a proactive, streamlined process. Here’s what sets it apart:

It’s Fully Electronic (Your Operations Team Will Thank You)

No more internal spreadsheets, shared inboxes, or legacy systems that crash more than they process. With ACH Positive Pay via Alkami, you move to a completely electronic process for managing ACH activity. Exception handling, rules management, and approvals can be done through a modern digital experience—no swivel-chairing between systems.

Let Business Clients Handle It Themselves (In a Good Way)

Imagine empowering your business clients to set up and manage their own ACH filters and exceptions—within clearly defined controls. Alkami’s platform offers self-service capabilities, so your operations team isn’t bogged down with every single change request or transaction review. This isn’t about handing off responsibility—it’s about giving businesses the tools to handle their own security with confidence.

Automate the Easy Stuff

Here’s a game-changer: ACH Positive Pay lets users define trusted companies (and blocked companies) and automate approvals based on rules like amount limits, frequency, and timeframes—so everyday transactions from known vendors don’t clog up your exception queue. That means fewer exceptions to review, fewer errors, and way less stress. Instead of catching every fish with the same net, you’re setting smart rules that handle the routine transactions automatically.

Bring Consistency to the Chaos

Many financial institutions manage ACH fraud protection through a patchwork of Demand Deposit Account (DDA) blocks and ACH platform filters. This setup can lead to inconsistent rule application, errors, and frustration. By enrolling business clients directly in ACH Positive Pay, you consolidate control in one place, reducing confusion and simplifying operations.

The result? A streamlined process for your team and a better experience for your business clients.

Time to Break Up with Manual ACH Blocks & Filters

We get it—ACH blocks and filters have been reliable companions over the years. But at some point, it’s time to move on. Between the manual work, the inconsistency, and the reactive nature of the process, it’s clear they’re not built for the digital banking experience your business clients expect.

Common Questions Financial Institutions Ask

  1. Is ACH Positive Pay only for large institutions?
    No. Any financial institution offering accounts to business, commercial, and corporate accounts should offer ACH Positive Pay. Whether you’re a regional credit union or a national bank, ACH Positive Pay scales to your needs. And with Alkami, it’s designed to integrate smoothly into your existing workflows.
  2. Will my operations team lose control?
    Not at all. In fact, they’ll gain it. ACH Positive Pay lets you decide what level of access to give business users. Set default rules, monitor exceptions, and customize workflows as needed.
  3. How does it help with compliance and audit readiness?
    Because it’s digital and rule-based, ACH Positive Pay keeps a clear audit trail.
  4. Can we still use ACH blocks and filters if needed?
    Yes, your operations team can still set up blocks and filters on your ACH platform, but think of ACH Positive Pay as a smarter evolution. Many institutions start by offering both, but as they—and their customers—get comfortable with the new system, they find they don’t want to go back.
