Ach Payments Setup Guide
Setting up ACH payments in 2026 requires four things: a payment processor that supports ACH (Stripe, Dwolla, or your bank's ACH API), bank account verification for each customer (micro-deposits or instant verification via Plaid), the right webhooks configured to handle async settlement, and a way to handle ACH returns when payments fail days after initiation.
Why This Happens
- Configuration gaps between tools or services
- Missing integrations or manual workarounds that weren't designed to scale
- Changes in vendor behavior, pricing, or API that weren't communicated clearly
What To Check First
- Verify your current setup matches the vendor's latest documentation
- Look for recent changes — platform updates, new team members, configuration drift
- Check if the problem is consistent or intermittent (different root causes, different fixes)
When To Escalate
- The problem is costing you money or customers per week
- You've spent more than 2 hours on it without progress
- A vendor quoted you more than $500 and you're not sure if it's necessary
Dealing with this right now?
The fastest path for most businesses: Stripe's ACH Direct Debit handles verification, payment, and webhook delivery in one integration. Use their pre-built payment element for the front end — it handles the bank account collection and verification UI without you building it. Configure webhooks for payment_intent.succeeded, payment_intent.payment_failed, and charge.dispute.created. Build the happy path first, then add return handling.
