A supplier portal checklist

Keep a private record when submitting an invoice.

Buyer-specific supplier portals can ask for invoice, purchase-order, and contact details without giving you a durable sent copy. SubmitSentry can help you keep a personal record of the ordinary fields you choose and the visible page around them.

Five captures are included free. Lifetime access is €9.99 once.

Before you submit

1. Complete the supplier portal yourself.
2. Open SubmitSentry and capture only the ordinary invoice fields you want to remember.
3. Review every row and remove bank details, tax identifiers, authentication data, or anything else that should not be stored.
4. Save the local record, then return to the portal and submit normally.

After submission

If the portal shows its own confirmation or a confirmation reference, attach that page to the same receipt. Keep using the portal's official invoice history, status page, email acknowledgement, or accounts-payable contact when those are available.

Know the limit: a local personal record is not proof of receipt, acceptance, approval, or payment. Only the buyer or portal can confirm those events.

SubmitSentry does not submit the invoice, inspect an uploaded invoice file, monitor the portal, or send receipt content to its service. Receipt content stays in Chrome on your device.
