An AI duplicate payment prevention agent reviews each payment proposal against paid items, items in the current batch and items pending in other batches, using supplier, amount, reference and invoice links.
Approved invoices are gathered for payment.
The agent compares each item with past payments.
It looks at card, bank and manual payments.
A treasury analyst clears or removes flagged items.
Cleared items proceed to the payment run.
Overpayments are tracked to credit or refund.
It looks beyond invoices to find the same obligation paid by different routes, such as a card payment and a bank transfer, or a payment to a supplier's old and new account.
It adds a clear flag to risky items in the run, with the earlier payment shown, and leaves the choice to remove or release to a person.
Once money has left, recovering it depends on the supplier's goodwill, so the control has to work before release, not after.
One bill paid by card and by transfer looks like two things.
The same invoice can sit in two runs prepared by different people.
A replacement invoice number hides the original.
Net balances conceal a payment made twice.
Chasing refunds takes time and may not succeed.
The agent reads every item in a payment proposal with its supplier, amount, invoice link and bank details.
It compares each item with paid items, other pending batches and open credits.
It checks whether the same invoice, PO or recurring charge is already settled by any route.
It marks suspect items with the matching earlier payment and a reason.
The run is not released until a person has cleared or removed each flagged item.
Bring a small sample and watch Flo work through it.
| Aspect | By hand | With the agent |
|---|---|---|
| Timing | Duplicates are caught after money leaves. | Checks run immediately before the payment run is released. |
| Channels | Card and bank payments are checked separately. | Payments are compared across channels. |
| Scope | Checks rely on invoice number only. | Checks use payee, amount, reference and invoice links. |
| Recovery | Recovery starts months later. | Overpayments are tracked from detection. |
| Control evidence | Proof of checking is thin. | A record shows each check and decision. |
| If | Then | Who decides |
|---|---|---|
| Payment matches a paid invoice on payee and amount | Holds it from the run | Treasury analyst decides |
| Invoice is already marked paid | Removes it from the run | None, rule applied |
| Same payee and amount appear in two channels | Flags it | Treasury analyst checks |
| Payment is a known recurring charge | Allows it after checking the schedule | Treasury analyst confirms |
| Duplicate payment is discovered after release | Opens a recovery item | AP lead contacts the supplier |
| Credit memo exists for the amount | Links it to the recovery | AP analyst applies it |
The agent compares manual payments entered later and flags overlap. Treasury decides whether to recall it.
The agent matches the refund to the recovery item and closes it. The analyst confirms.
The agent links old and new vendor records for comparison. The vendor admin confirms the link.
The agent allows for small fee differences by matching on reference. The analyst confirms.

Stopped before release = number of flagged items removed from runs in the periodThis shows how many duplicate payments were prevented rather than recovered. Compare it with duplicates found after payment to judge coverage.
Quick answers to what people ask most about duplicate payment prevention.
Book a demoIt is the control that checks proposed payments against previous and pending ones, to stop the same amount being paid twice for the same obligation.
Invoice detection happens earlier and looks at documents. Payment prevention looks at the payment run, and catches repeats that came through different invoices or methods.
It flags items and recommends removal. A finance reviewer removes them or releases the run. The agent does not release or cancel payments.
The agent can assemble the evidence, and a person contacts the supplier or bank to recover the funds.
Duplicate invoice detection is the check that finds an invoice that has already been received or paid, whether as an exact copy or with small changes to the number, date or amount.
→Bank detail change verification is the control applied when an existing supplier asks to change its bank account, a common route for payment fraud.
→Bank detail verification is the check that a supplier's bank account details are genuine and belong to that supplier before any payment is set up.
→Invoice anomaly detection is the practice of finding invoices that look out of pattern, for example an unusual amount, a new item, an odd timing or a different format from the same supplier.
