AI agents for accounting
The identity and email layer for accounting AI agents. Every agent gets its own invoice and receipt inbox beside QuickBooks or Xero, with whitelist controls and a full audit trail.
The problem
Client invoices and receipt forwards still land in a shared practice Gmail that no single agent owns.
QuickBooks and Xero keep the ledger, but neither gives the agent a reply address for the invoice thread.
Bill.com runs AP and bill pay workflows without giving the agent its own sender identity on the email side.
Expensify collects receipts into a human mailbox, so the agent still borrows a person address to chase missing docs.
Nylas and Unipile OAuth a human accountant mailbox, which breaks when the agent needs per-client isolation and financial allowlists.
The solution
AgentMail is the identity and email layer for accounting agents.
Dedicated inbox per client agent
Each bookkeeping agent gets its own address so invoice and receipt threads stay on one persistent identity.
Whitelist and blacklist at the inbox
Control who can mail the agent and who it can send to at the infrastructure layer, the same pattern Balance uses for client financial data.
Realtime message.received webhooks
When a client forwards a receipt or replies to an invoice chase, the agent gets the message and can answer in the same thread.
Full audit trail
Every send, reply, and routing decision is logged and queryable, so month-end disputes take minutes instead of a mailbox search.
What your accounting agents can do
AP
Invoice and AP request triage
The agent owns the inbox that vendors mail, classifies invoice threads, and escalates anything that needs a human accountant.
Receipts
Receipt and document collection
Clients forward receipts to the agent address. The agent acknowledges, stores the attachment, and chases missing docs in-thread.
Month-end
Month-end client chase threads
The agent sends the document request list, follows up on open items, and keeps the full thread for the human sign-off.
Multi-client
Multi-client pods with isolated inboxes
Pods keep each client inbox and thread history separated when one practice or product serves many SMB books.
AgentMail is built to scale.
Redundant infrastructure spanning multiple regions, so a message to your agent lands even when a region does not.
Provision an inbox in milliseconds. Nothing to verify, nothing to wait on.
Typed SDKs, REST endpoints, and webhooks. Your first send goes out the same afternoon.
