Local browser-first duplicate payment review

Catch duplicate-payment risk before the payment run leaves AP.

Check current payment-run rows against paid-invoice history and vendor aliases. Start with sample or redacted CSVs, inspect a HOLD / REVIEW / CLEAR queue, then decide whether the scanner kit fits your AP process.

No ERP login / no bank connection / no cloud upload / sample or redacted rows first.

The first buyer path is browser-readable reports and CSV outputs. Optional scripts are only for advanced users later.

HOLD REVIEW CLEAR
Sample queue proof HOLD - Same vendor, invoice, amount, and currency already paid - check paid history before release.

Start with fake, sample, redacted, or header-only CSVs before private AP data.

Not sure your payment-run, paid-history, or vendor-alias columns fit? Use setup help or email [email protected] before buying. Send headers or fake/redacted rows only.

  • No ERP login
  • No bank connection
  • No cloud upload
  • Start with headers, fake rows, or redacted CSV
Sample duplicate-payment scan Sample data only
HOLD Pause before release

Already-paid or duplicate-like evidence appears in the current run or paid history.

REVIEW Route to AP

Same vendor and amount, weak invoice reference, or alias match needs confirmation.

CLEAR Continue normal path

No starter duplicate-payment signal appears on the sample row.

Status Signal Buyer next step
HOLD Same vendor, invoice, amount, and currency already paid Check paid history before release.
REVIEW Same vendor and amount with invoice-number variation Confirm invoice and vendor statement.
CLEAR No starter duplicate-payment signal Continue through normal approval controls.

Buyer-visible proof

See the review logic before you trust the download.

OpsProof Tools should feel inspectable in the first minute: start with sample, fake, redacted, or header-only payment-run data and see why duplicate-like rows become HOLD or REVIEW before committing to deeper files.

Payment run Paid history Vendor aliases HOLD / REVIEW / CLEAR
  • Exact duplicate and invoice-number variation evidence is explained row by row.
  • Vendor alias groups are visible as review questions, not hidden automated merges.
  • The first buyer path stays no upload and no Python.

Start with a duplicate-payment sample queue, not a sales demo that needs your systems.

Most AP teams cannot send real payment data to a new tool on day one. This first path is designed for a buyer who wants evidence: inspect sample payment-run rows, see what the queue would hold, and only then decide whether a paid kit or setup help makes sense.

1

Sample hold queue

Use sample, fake, redacted, or header-only CSVs in a static browser page. The first pass explains what duplicate-payment evidence would be needed.

2

Local browser review

Open the reviewer in a browser and see how HOLD, REVIEW, and CLEAR rows are explained.

3

Choose the right purchase

Use the free proof pack first, then buy the scanner kit, bundle, or setup service only if the workflow matches.

What buyers can inspect before paying

The page is not selling a generic template library. It is selling confidence that duplicate-payment review logic can be tested locally before a production rollout.

Browser sample queue

Try the public demo or open the local file, paste fake or redacted CSV, and inspect duplicate-payment HOLD / REVIEW / CLEAR logic without uploading to a cloud service.

Files needed

Current payment-run CSV, paid-invoice history, and optional vendor alias or vendor master export are enough for the first review shape.

Review evidence

Review sample outputs tied to duplicate-payment signals: exact already-paid rows, invoice-number variations, recent same-vendor payments, and vendor aliases.

Ready to self-serve? Try the sample queue first. Buy the USD19 scanner kit for the focused duplicate-payment workflow, or the USD49 bundle when you want broader AP review assets.

A purchase path for buyers who need to judge capability first

No real AP files are collected on this site. Payhip handles download delivery and checkout; this page explains what to inspect before choosing a scanner kit, broader review bundle, or setup service.

Sample queue proof

Use this when you want sample duplicate-payment outputs and the browser-first starting point before buying anything.

This helps decide whether the hold queue model fits your AP process. It is not the full scanner kit.

  • Public sample hold queue
  • No-upload readiness proof
  • Open-first browser preview
  • Buyer decision guide

Duplicate Payment Scanner Kit

Use this when duplicate-payment review is the immediate problem and you want sample inputs, mapped outputs, reports, and a self-serve workflow.

This is the focused entry product. The broader USD49 bundle is still available if you also need invoice validation, payment matching, SOP, matrix, and workbook assets.

  • Current run vs paid history review
  • HOLD / REVIEW / CLEAR queue outputs
  • Vendor alias review
  • HTML and CSV report examples

First-run setup service

Use this when mapping your exports correctly is more valuable than doing the first pass yourself. Target turnaround is 3 business days after usable intake files.

Partial, blocked, or unsure after the free check? Use setup for duplicate-payment column mapping and first-run readiness help.

  • Setup service, not ZIP-only
  • Payment-run export-fit review
  • Column mapping guidance
  • First-run readiness note plus one clarification pass

Who this is for

Good fit

AP, finance ops, founders, controllers, bookkeepers, or consultants who already export CSV or Excel files and want a clearer duplicate-payment review queue before release.

Not a fit

Teams looking for direct ERP writeback, automatic bank access, OCR invoice capture, live fraud guarantees, or a replacement for approvals and accounting controls.

Best first action

Try the sample hold queue, open the free proof pack, and compare the queue language against your current payment-run review process.

Buying questions

Does this site collect finance data?

No. There is no upload form or external submission on this page. The proof path starts with files that open locally in your browser.

Why use Payhip for checkout?

Payhip keeps payment, receipt, VAT/tax handling where applicable, and file delivery outside this static site. The marketing site can stay simple and deployable on Cloudflare Pages.

Do buyers need Python?

No for the first buyer-facing path. Try the public browser demo, or open the downloaded browser reviewer and proof pages locally. Optional scripts are an advanced path for teams that want more control later.

What should I try first?

Start with the sample hold queue and free proof pack. If the queue shape matches your AP process, move to the USD19 scanner kit, broader USD49 bundle, or USD149 setup service.

Does it guarantee every duplicate payment is found?

No. It is a pre-payment review assistant and evidence queue, not a fraud guarantee, audit opinion, or replacement for AP approval controls.

What files are needed?

The strongest first run uses a current payment-run export, paid-invoice history, and optional vendor alias or vendor master export. For first contact, use sample, fake, redacted, or header-only files.
