Now ask
What the AI answers to the test question:- It says LedgerSync is ready: ask anything below.
- It says we’re reviewing your new firm: add your clients now. Bank connections open after the review.
- Anything else: see Troubleshooting.
New account? Add your first client
A new LedgerSync account has no clients yet. Add your first one. Acme is an example: use your client’s name.1
Add a client and get a bank link
Ask: “Add my client Acme and give me a link to connect their bank.”
2
Open the link and connect the bank
Open the link. Pick your client’s bank and sign in with their bank login. This happens on a LedgerSync
page, never in the chat.Don’t have their bank login? Send the link to your client by email or text, and they do it. The link
works for 3 days.
3
Ask about their bank
When the bank is connected, ask: “Show Acme’s bank balances.”
More things to ask
Is a bank supported?
“Does LedgerSync work with First National Bank?”
Find a client
“Find my client Acme.”
Balances
“Show Acme’s bank balances.”
Transactions
“Show last month’s transactions for Acme’s checking account.”
Statements
“Get Acme’s September bank statement.”
Problems
“Which of my clients’ banks are not working?”
Connect a bank
“Send Acme a link to connect their bank.”
Nobody types a bank password in the chat. When a bank needs a password, the AI gives you a link to a
LedgerSync page. The password goes there.
