Sejin Jang - Owner

I am a certified bookkeeper from Durham College, and I specialize in eCommerce and small business bookkeeping using QuickBooks Online, Wave Financial, and spreadsheets. I also leverage apps such as Google Docs/Sheets/Drive, Hubdoc, Toggl, Tsheets, and Asana to help make your business run more smoothly.

Sebastien Benoit - Tech Guy

My specialty is technology, and Sejin calls me her 'tech guy', a title I think suits me! I'm driven to provide technology solutions that save you time and reduce errors.

Specifically, I look after pulling all the data from every channel/portal and summarizing it in a way that makes sense for you. My playground is Google Sheets/Drive/Scripts which is fully collaborative and can help us work together with ease. If you’re frustrated with how your current financial software or spreadsheet works, please let me help!
