Customers ask “Where's my invoice?” and account managers ask “Has Acme paid yet?”—but only one or two people have QuickBooks access. That bottleneck means delayed responses and frustrated customers waiting on someone to look it up.
The QuickBooks integration lets your AI agent pull invoice details, customer balances, transaction history, and expense records on demand. Support reps and account managers get answers in seconds without needing a QuickBooks login.
| Action | Description |
|---|---|
| Get Invoice | Look up an invoice by number or customer name and return status, amount, and due date |
| Customer Balance | Get the outstanding balance for a specific customer |
| Transaction History | List recent payments, credits, and charges for a customer |
| Expense Lookup | Find expenses by vendor, date range, or category |
| Field | Description | Example |
|---|---|---|
| Access Token | OAuth 2.0 access token (managed automatically via OAuth flow) | eyJlbm... |
| Realm ID | Your QuickBooks company identifier (populated automatically) | 123456789 |
After setup, open your AI agent and try these realistic queries:
ChatSpark auto-refreshes OAuth tokens. If you see token errors, try disconnecting and reconnecting via the OAuth flow in AI Actions settings.
If you manage multiple QuickBooks companies, make sure you authorized the correct one during the OAuth flow. Disconnect and reconnect selecting the right company.
Verify the invoice number format. QuickBooks assigns sequential numbers by default, but custom numbering schemes may require exact matches.
