We'd especially like to hear about

• A calculation or translation that looks wrong.
• A job description you would like to see in the invoice and estimate lists.
• A tool that would save you time in your trade.

We usually reply within a few business days. Please don't send passwords, bank details or other sensitive information by email.

We can't give legal, tax or accounting advice. For those questions, talk to a licensed professional in your state.
