Capital One positive pay file: the Intellix Check Services format

Capital One runs positive pay through Intellix, its commercial and business treasury platform. The feature lives under Services > Check Services, and the bank documents the exact import layout in its public Check Services Reference Guide. That makes Capital One one of the banks where you can build a positive pay file with confidence, because you are matching a published spec rather than guessing.

This page walks through how check issue files work in Intellix, the two file formats Capital One ships, the custom import map for anything that does not fit, and how to turn your check register into a file that imports cleanly. As always, confirm your first file with your treasury contact before you rely on it.

How positive pay works at Capital One

With Positive Pay, you tell the bank which checks you issued. Capital One then compares every check presented for payment against that list. If a serial number (check number) or amount does not match the issue data you submitted, the bank creates an exception. You review exceptions in Intellix and decide to pay or return each one before a daily cutoff. If you do not decide in time, the bank applies your organization's default decision.

If you subscribe to Payee Positive Pay, the bank also compares the payee name on the check against the payee in your issue data, so the payee name becomes a required field in your file. Capital One also offers Reverse Positive Pay, where every presented check is shown to you for a pay-or-return decision without an issue file. This page focuses on standard Positive Pay, which needs the issue file.

Two ways to submit issue data

Capital One lets you get check issue and void information to the bank in two ways:

One thing to plan around: imported files must be approved on the Import Results screen before they are sent to the bank. Depending on your permissions and your organization's dual-control policy, you may approve your own import, or a second person may have to. Capital One's guide notes the bank processes check issue and void information roughly every 75 minutes, starting at 7:45 AM ET with a cutoff of 5:45 PM ET, so submit and approve with time to spare.

The Capital One file format (published spec)

Intellix ships two system-defined formats. If your file already matches one of these, you can import without building anything. According to Capital One's Check Services Reference Guide, the layouts are:

Comma delimited

Fixed width

An ABA or Bank Code is required, but you can supply it as a default value in the import map instead of repeating it on every row. The "implied decimal point" note matters: an amount of $1,250.00 is written as 125000, not 1250.00. Capital One's spec is detailed, but bank treasury platforms get updated. Treat the layout here as a starting point and confirm the current spec against the copy in your own Intellix portal before your first production run.

When your file does not match: the custom import map

If your register does not line up with either system format, Intellix has a Custom Import Map under Services > Check Services > Import Map. You pick Delimited or Fixed, choose Import Check Issue/Void as the payment type, then set the details: which row to start on, the field and string delimiters, the date format and separator, the number of implied decimal positions, and the abbreviations you use for issue and void (the default is "I" and "V", and that field is case sensitive). Then you map each field in your file to the application field by number. This is Capital One's way of accepting almost any column order without forcing you to rebuild your accounting export.

Turning your check register into the file

QuickBooks, Xero, and most accounting tools do not export a positive pay file natively. QuickBooks can hand you a check register or transaction report, but the positive pay layout is something you have to produce separately.

PositivePayMaker is a free, browser-based tool that does that step. You upload your check register as CSV or Excel, map your columns (check number, amount, date, payee, account), and it produces a positive pay file. Because Capital One publishes its layout, you can match the comma-delimited or fixed-width format directly, or use the custom format builder to mirror the exact field order and widths from your Intellix import map. The tool runs entirely in your browser, so your check data never leaves your computer. You can also run a generated file through the file format reference to sanity-check field positions before you upload.

Where paid tools fit

If you process high check volume across several banks and want desktop software with vendor support, paid options exist. Treasury Software's Bank Positive Pay is installed Windows software, roughly $29.95 to $89.95 per month, with 350-plus prebuilt layouts. Big Red Consulting's PositivePay File Creator runs about $119 the first year and $99 per year after, Windows only, and its QuickBooks edition needs Excel installed. MoneyThumb and ProperSoft sell paid desktop converters as well. Those make sense when you need a maintained library of formats or batch automation. For a single bank like Capital One with a published spec, a free browser tool usually covers the same ground.

Enrollment and support

Positive Pay and Check Services are entitlements your organization turns on through Intellix. If you do not see Check Services in your menu, your Client Administrator controls access, or you can reach Capital One's Treasury Management Client Service team at 866-632-8888 (Option 2) or [email protected] to enroll or ask which formats your account supports.

Before you trust the first file

Build one file, import it into Intellix, and check the Import Results screen. If a file rejects, you can hover over the File ID to see the reason, and the Check Issue File Import report shows the detail. Confirm the imported items match your register exactly before you start relying on the integration for production. A two-minute check on the first run prevents a check from being flagged or returned later.
