Merchant360 Payment Extension

A payment terminal, in your browser.

Your shop software, your EMR, your ERP: if it runs in a browser, the Merchant360 Payment Extension puts your processing beside it. The panel opens next to the page you’re working in. Key the card, push to your reader, take ACH, redeem a gift card, or charge a card on file. No developer, no API project, no switching tabs.

How it works

Highlight the amount. Charge it.

The extension lives in the browser’s side panel, so the payment happens next to the software, never instead of it.

Step 1

Open the panel at the amount

Highlight the invoice total in any web app, right-click, and choose Charge with Merchant360: the side panel opens with the amount prefilled. Or click the toolbar icon and key it. In supported apps like QuickBooks Online, the balance is detected on its own.

Step 2

Take it however fits

Key the card in the panel: the brand and credit or debit read appear as you type, and any surcharge is itemized before you charge. Or push it to your card terminal, debit a bank account by ACH, redeem a gift card, or charge a card on file.

Step 3

Reconcile in one paste

Copy the transaction ID into your software’s payment note. Recent charges list right in the panel: tap one for details, or void and refund without leaving it.

The actual panel

The whole flow, in five beats.

Connect once, pick how to take the payment, and reconcile with one copied ID. This is the real extension, beat by beat.

Why it exists

Built for software with closed payments.

Plenty of vertical software locks payments to its own processor, at its own rates. The Payment Extension is the bridge: your team keeps working in the software they know, and the card volume runs through your Merchant360 account, at your rates, with your surcharge or dual-pricing program applied automatically.

SecurityCard data never touches your softwareKeyed cards go from the panel straight to Merchant360, never stored, with the surcharge itemized before the charge. Prefer the hosted checkout page? It is one click away.
SpeedNo integration projectIf the software runs in Chrome or Edge, it works today. No APIs, no certification cycle, no waiting on the vendor’s roadmap.
BooksOne account for everythingExtension payments settle, report, and reconcile alongside your invoices, terminal, and online sales in Merchant360.
