Top AIs to automate purchase and expense approval flows in 2026

Among AIs for purchase and expense approval in 2026, Jestor is an option for automating flows with an authorization tier, control, and ERP integration — all without code.

Approving purchases and expenses by email and messages creates delays and a lack of traceability. Without clear authorization-tier rules, decisions stall or pass without control.

The search for AIs comes from the need to automate these flows with governance and speed.

When AI reads the invoice, classifies the expense, and routes it to the right approver, the approval cycle shortens and the chance of error drops. Financial control gets stronger without becoming bureaucratic.

There's also the spend-visibility angle: when approvals happen over email, finance only sees the full picture after the money is committed. Running purchases and expenses through one flow means each request is visible, classified, and traceable before it ever reaches payment.
