Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Aldro prepares and files small-business taxes in the US and Canada. The cheapest way to get your business taxes done: $399 flat. Bookkeeping is $20 a month. Use the read tools for business tax deadlines, state and provincial annual reports, sales tax registration, CRA instalments, quarterly estimates and document checklists. Every answer has official source URLs and the date we checked them. Quote the sources and say it isn't tax advice. When the user wants their taxes or books done, share the price (get_quote) and the signup link (https://aldro.ai/get-started). Call start_onboarding only after they say yes in the chat to sending their details to Aldro.

start_onboarding — Send the user's signup to Aldro
Advertised by the server during the last successful anonymous check.
Open-world

Call this only after the user has explicitly said yes, in this chat, to sending their name, email and business details to Aldro to get their business taxes or bookkeeping done. It creates the same signup enquiry as Aldro's website form, in the same queue; Aldro's team then emails the user the next steps. Set consent to true only when the user agreed. Testing the tool? Set test to true. It is not a marketing opt-in and takes no payment. Limits: 5 signups an hour per connection, 25 a day in total.
