A Fee You Barely Notice — Until You Do
When you signed up for your property management platform, the $1.50 or $2.49 per-ACH-transaction fee probably seemed reasonable. One payment, one small fee. No big deal.
But fees that scale with your portfolio are a different kind of cost. They do not show up as a line item you negotiate once — they grow silently every time you add a unit.
The Math at Scale
Here is what per-transaction ACH fees actually cost across common portfolio sizes:
| Units | $0.50/txn | $1.50/txn | $2.49/txn |
|---|---|---|---|
| 25 | $12.50 | $37.50 | $62.25 |
| 50 | $25.00 | $75.00 | $124.50 |
| 100 | $50.00 | $150.00 | $249.00 |
| 200 | $100.00 | $300.00 | $498.00 |
| 500 | $250.00 | $750.00 | $1,245.00 |
At 200 units and $2.49 per transaction, you are paying nearly $6,000 a year just to move money from one bank account to another. That is not a feature — that is a toll.
Why Do Platforms Charge This Way?
Most property management platforms do not actually connect to your bank. They act as payment intermediaries — processing each transaction through a third-party payment processor who charges them per transaction. They pass that cost to you, often with a markup.
This model works well for the platform. It scales their revenue with your growth. But it works against you for the same reason.
What Your Bank Actually Charges
If you originate ACH transactions directly through your bank, the fee structure looks completely different. Most commercial banks bundle ACH origination into your business account or charge a small monthly fee — not a per-transaction fee that scales with volume.
The catch is that your bank expects a NACHA-formatted file. You cannot just type in account numbers and amounts. The file has a strict fixed-width format with batch controls, entry hashes, and header records that have to be exactly right.
That formatting requirement is what keeps most property managers locked into per-transaction platforms. It is not that direct ACH is hard — it is that nobody wants to learn the NACHA spec.
Breaking the Per-Transaction Cycle
The way out is straightforward: generate your own NACHA files and send them to your bank. You keep the same ACH workflow your tenants are already authorized for, but you stop paying a fee every time the system moves money.
What you need:
- ACH origination through your bank — most commercial banks offer this through their treasury department
- A tool that creates valid NACHA files — so you do not have to learn the format yourself
- A way to transmit the file — either uploading to your bank's portal or sending via SFTP
Flat Pricing That Stays Flat
FiSTWorks handles the NACHA file creation and SFTP transmission for a flat monthly price. Add tenants, set amounts, generate the file, and send it to your bank. Whether you collect from 10 units or 1,000, the price does not change.
No per-transaction fees. No middleman payment processor. Just you and your bank.
