Same ride paid on the corporate card and claimed as out-of-pocket. Held for AP review before the next payment run.
Single-system duplicate checks catch the obvious repeat. These four patterns cross systems, people, file formats or weeks, which is why they survive.
How it happens
A charge on the corporate card is also filed as a cash reimbursement, often weeks later from a different system.
How Phyto Nex AI catches it
Card feeds and expense reports are matched on amount, normalized merchant, timestamp and trip or ticket ID.
$3,214.60 Delta fare on the Amex feed and as an out-of-pocket Concur entry 19 days later.
How it happens
The host pays and expenses the dinner. A colleague who attended submits a photo of the same receipt.
How Phyto Nex AI catches it
Receipt image fingerprints and attendee lists are compared across submitters, not just within one report.
$412.86 at a Chicago steakhouse, filed by both the regional manager and an account executive.
How it happens
An emailed ride receipt is filed, then a photo of the printed copy is filed on a later report.
How Phyto Nex AI catches it
Ride IDs, pickup and drop-off text, and amounts are read from both images, regardless of file type or hash.
$57.35 Lyft ride, PDF on August 30 and phone photo on September 12.
How it happens
The same amount is resubmitted weeks apart with the date nudged or a reference number removed.
How Phyto Nex AI catches it
Fare basis, route, merchant and amount match even when the date drifts and identifiers are missing.
$3,214.60 ATL to LAX fare filed on July 8 and again on August 5 without the ticket number.
Every match shows which signals fired and how much each contributed, so AP can see why a pair was linked before acting on it.
| Signal | Weight | How it is measured |
|---|---|---|
| Exact or near amount | High | Within $0.01, or within currency conversion tolerance for foreign spend |
| Receipt image fingerprint | High | Perceptual hash survives cropping, rotation and recompression |
| Trip, ticket or folio number | High | Read by OCR from both documents |
| Normalized merchant | Medium | UBER *TRIP HELP.UBER.COM and Uber Trip resolve to one merchant |
| Timestamp proximity | Medium | Minutes for rides, days for dinners, weeks for airfare |
| Same or overlapping attendees | Medium | Attendee lists and submitter are compared across reports |
| Route and fare basis | Medium | Origin, destination and fare class from e-ticket receipts |

Hold
Both records are held before the next payment run, with the match evidence attached.
02
AP review
AP sees the pair side by side with signals and confidence, and confirms or dismisses.
03
Employee message
A neutral draft asks the employee which record to keep. AP approves it first.
04
Recovery
If one was already paid, a repayment request is drafted for AP approval.

Pattern log
Repeat duplicates by the same submitter are tracked for the controller.
A $3,200 flight showed up on the corporate card and again on an out-of-pocket report three weeks later. Two different systems, two different approvers. Phyto Nex AI linked them before the payment batch went out.

Duplicate airfare caught before reimbursement
The default window is 120 days across every connected source, which covers the IRS return-of-excess safe harbor period and most quarterly close cycles. You can extend it to 365 days for annual audits.
Not on amount alone. Exact amount is one signal among several. Without a matching receipt fingerprint, trip ID, ticket number or overlapping attendee list, the confidence stays below the review threshold.
No. Most duplicates are honest mistakes, such as a card charge also filed out of pocket. The drafted message says so, asks the employee to confirm which record to keep, and AP approves it before sending.
Yes. Connect both during a migration and Phyto Nex AI normalizes them into one ledger. Migrations are when cross-system duplicates spike, because habits outlast tools.
Phyto Nex AI lists the recovery amount and drafts a repayment request. AP approves it and records the repayment or deduction in your expense or payroll system.
