Email your Botkeeper and follow the process outlined by them. They'll email you after it's been added.
Just email your Botkeeper and ask to add a certain expense category to their Chart of Accounts. The bot may ask follow up questions like, "Should this be a subcategory under another expense category?" Once the bot adds the new expense category, it will sync to all other data systems aligned with your accounting software (Bill.com, Expensify, etc.). Your Botkeeper will email you when the new expense category has been added. Just like that!
