About American Express AccessLine
American Express AccessLine is a business payment solution offered by American Express that lets companies use their American Express business or corporate card to pay domestic and international suppliers. It is designed to help businesses manage cash flow, earn card rewards, and simplify accounts payable by converting supplier invoices into card-based payments, even when the supplier does not accept American Express directly. In Australia, these transactions may appear on statements with descriptors like “AMEX ACCESSLINE*AMEX Sydney”.
This charge typically appears when a business has used AccessLine to pay a supplier, contractor, or other business expense through the American Express portal. The transaction amount usually corresponds to an invoice or group of invoices paid via AccessLine, sometimes plus a service fee. It is a business-oriented service, so these charges most often show up on American Express business, corporate, or company cards rather than on consumer cards.
If you have questions about an AccessLine charge, log in to your American Express online account or the Amex Business/Corporate portal and check the transaction details and associated remittance or invoice references. Finance or accounts payable staff should review internal payment records to match the AccessLine transaction to specific supplier invoices. For further assistance, cardmembers can contact the American Express customer service number on the back of their card or use secure messaging via the Amex website or app to request an invoice copy, fee breakdown, or dispute a transaction if it appears incorrect.
