Zions Bank Positive Pay: building and uploading your check issue file
If you write business checks on a Zions Bank account, positive pay is the service that stops a forged or altered check from clearing. You send the bank a list of the checks you actually issued. When a check hits your account, Zions matches it against that list. Anything that does not match (wrong amount, unknown check number, a payee that was changed) gets flagged as an exception, and you decide whether to pay or return it before the money leaves.
The piece most bookkeepers get stuck on is the file. This page explains how positive pay works at Zions Bank, what their issued check file involves, and how to produce a file that matches the layout Zions set up for your account, without buying desktop software.
What Zions Bank offers
Zions Bank runs positive pay through its Treasury Internet Banking platform. Two related services are sold separately:
- Check Positive Pay with Payee Match. Matches the check number, dollar amount, and payee name on each presented check against your issued list. Payee match is what catches a check where someone altered the name of the recipient.
- ACH Positive Pay. A filter that lets you designate which ACH debits are authorized to hit the account, so unexpected electronic withdrawals are held for review.
You enroll by talking to a banker or Treasury Management Officer. Zions does not turn positive pay on by default; it is a treasury service you add to a business account. Their marketing says the system "accepts virtually any file format," which is accurate but also the source of most confusion. It does not mean any file works out of the box. It means Zions builds an import definition that tells the platform how to read your file.
How the issued check file works at Zions
Inside Treasury Internet Banking you can enter checks two ways. You can key them in one at a time, which is fine for a handful of manual checks. Or you can upload an issued check file, which is what you want once you are printing checks in batches.
A few specifics about the Zions upload, confirmed from their published Positive Pay quick reference guide and service pages:
- Issued check files are imported in .CSV or .TXT format.
- Before you can import, an import definition has to be created and tested with the bank. You coordinate this with Treasury Management Technical Support during onboarding. The input file specifications and test-file instructions come in the welcome materials Zions sends when your service is set up.
- At upload time you pick your saved import definition from a drop-down, then browse to or drag and drop the file your accounting system produced, and click Upload.
- The file describes the checks you wrote: at minimum the account number, check number, dollar amount, and issue date, plus the payee name if you use payee match. Voided checks are typically flagged in the same file or entered separately.
Because the layout is defined per customer, there is no single public "Zions positive pay format" to copy. Your file has to match the import definition Zions built for your account. If you are not certain of the exact column order, field widths, or date format, the authoritative source is the welcome email and input file specification from your onboarding, or your Treasury Management contact. Zions Bank treasury support can be reached at 888-307-3411. Do not guess at the layout from a generic template; a mismatched file is the most common reason an upload fails.
One shortcut worth knowing: if you pay through Deluxe Payment Exchange (DPX) with positive pay fully integrated, DPX sends the issuance file to Zions automatically, so you never upload it yourself. That only applies to checks issued through DPX, not checks printed from QuickBooks or another system.
QuickBooks will not export this file
This trips people up. QuickBooks Desktop and QuickBooks Online both print checks, but neither one exports a positive pay file natively. You can pull a check register or a check detail report out of QuickBooks, but turning that report into the CSV or TXT layout Zions expects is a manual reformatting job every cycle. That gap is exactly why positive pay tools exist.
Build the file for free with PositivePayMaker
PositivePayMaker is a free tool that converts your check register into a positive pay file. You export a CSV or Excel file from QuickBooks or any accounting system, drop it in, map your columns to check number, amount, date, and payee, and it produces the issue file. The whole thing runs in your browser. Your check data is processed on your own machine and never gets uploaded to a server, which matters when the file is a list of every check you wrote and to whom.
Since Zions assigns each customer a specific import definition rather than publishing one universal layout, the custom format builder is the part to use here. You set the column order, choose CSV or fixed-width, set the date format, and pad fields to the widths your import definition specifies. Save that as your Zions layout and reuse it every cycle. If your situation matches a common pattern, a generic CSV or fixed-width preset may already be close enough to adjust from. The built-in file validator lets you sanity-check the output before you upload it to Treasury Internet Banking.
PositivePayMaker ships with 11 bank layouts and a format builder, and the whole tool is free. The catch is that it does not have a verified, published Zions layout baked in, because Zions does not publish one. You will match your account's import definition yourself using the builder. That takes a few minutes the first time and nothing thereafter.
When paid software might fit instead
If you generate very high volumes or want a vendor to maintain layouts for you, a paid desktop tool can be reasonable. Big Red Consulting's PositivePay File Creator runs about $119 the first year and $99 per year after, is Windows-only, and its QuickBooks Online edition needs Excel installed. Treasury Software's Bank Positive Pay is installed Windows software in the roughly $29.95 to $89.95 per month range and ships with hundreds of prebuilt bank layouts. MoneyThumb and ProperSoft also sell paid desktop converters. These cost money and most are Windows-only, but for a busy AP department the prebuilt-layout libraries and vendor support can be worth it. For most small businesses producing one issue file per check run, a free browser tool covers the job.
Always verify the first file with Zions
Whatever you use to build the file, treat the first one as a test. Generate it, run it through the validator, and either submit it as the test file Zions asks for during setup or confirm with your Treasury Management contact that it imported cleanly and matched your checks. Banks change platforms and layouts over time, and your import definition is specific to your account, so the only real confirmation is Zions accepting the file. Once a layout is proven, you can run it the same way every cycle.
