Suan is 算 (pronounced "swan"), which means to calculate or plan. It comes from the Chinese phrase 精打细算: careful, detailed planning. That's what running a small business takes, and it's what these tools help you do. The swan in our seal is a nod to the pronunciation.
SuanSupply was founded by a bilingual English and Mandarin speaker who has worked on both sides of trade between China and North America. The first tools came from watching small brands struggle with the same problems: quotes that didn't match what they asked for, samples that came back wrong, and orders that looked profitable until freight and fees showed up.
Every tool runs in your web browser. There's nothing to install, no account to create and no monthly fee, and everything you type stays on your device.
