About Single O
Single O is a specialty coffee roaster and café operator based in Sydney, Australia, focused on sourcing, roasting, and serving high-quality, ethically and transparently traded coffee. They roast a rotating range of single origins and blends for espresso and filter, sell beans and brewing gear online via singleo.com, and operate branded cafés, including their flagship in Surry Hills and CBD locations. Single O also supplies wholesale coffee to cafés, restaurants, offices, and other hospitality venues across Australia.
A Single O charge may appear on your bank or card statement when you purchase coffee, food, or merchandise in one of their cafés, buy beans or brewing equipment through their online store, or sign up for a recurring coffee subscription. Statement descriptors may appear as “SINGLE O”, “SINGLE O SYDNEY”, “SINGLE O CAFE”, or similar variants. You might also see charges for recurring deliveries (e.g., weekly or monthly coffee subscriptions), one-off web shop orders, gift card purchases, or temporary authorization holds if a payment was pre-authorised (for example, for a café tab or mobile wallet transaction).
If you’re unsure about a Single O charge, start by checking recent café visits, online orders at singleo.com, and any coffee subscription or office/wholesale account you may have. Look for email receipts from Single O (including in your spam folder) and log into your Single O online account to review order history and subscription billing dates. For further assistance or to dispute or clarify a charge, you can reach their customer service via the contact form or email listed on singleo.com, or call the café/roastery directly during business hours; in most cases, they can look up your transaction by date, amount, and the last four digits of your card and help with issues like duplicate charges, refunds, or subscription changes.
