How to set up a spend approval workflow

Why after-the-fact approval fails

In most companies, approval happens too late. Someone spends, the charge lands, and finance reviews it at month-end, when the only options are to accept it or start an awkward conversation.

By then the money is gone. Real control means deciding what is allowed before the spend, not arguing about it after. Virtual cards let you build that approval into the card itself and the workflow around it. If the format is new, start with what a virtual card is.

Let the card limit do the first layer of approval

The simplest approval is a spending limit. Set each card to its budget, and the routine, in-policy spend simply goes through, while a charge above the cap can be blocked based on your controls.

That means a reviewer is not rubber-stamping every coffee and software seat. The card pre-approves what is within limit, so the people reviewing only spend their time on the exceptions.

Route charges to the right reviewer

For the spend that does need eyes, assign a reviewer so a transaction goes to the manager responsible. A To Review list shows what is waiting, and a Requested tab tracks what has been asked for.

Set review rules so the routing is automatic: charges from a card, a wallet, a user, or above an amount can be sent to the right approver without anyone forwarding emails. The reviewer confirms or questions the charge, and the record updates.

Add rules and alerts so nothing slips

A workflow only works if it runs without babysitting. Create review rules for who approves what, and use alert rules to flag spend that needs attention.

• Send charges above a set amount to a senior reviewer.
• Route a specific card or wallet to the manager who owns it.
• Flag a category or merchant for a closer look based on supported controls.
• Keep a To Review queue so approvals do not pile up unseen.

This is the same control structure multi-site operators use when they manage spend across locations.

Keep an audit log of every approval

Approvals are only as good as the record behind them. Each transaction carries an activity log, and changes are timestamped, so you can see who approved a charge and when.

When an owner, a board, or an auditor asks how a charge was authorized, the answer is already attached: the reviewer, the decision, and the receipt. There is nothing to reconstruct.

Roll the workflow out without slowing the team

Start light. Cap the cards, assign reviewers for the spend that matters, and add one or two review rules. Let the limits handle the routine and reserve human approval for the exceptions.

As you grow, add rules and reviewers so the workflow scales with the team. Pair it with receipt capture so every approved charge also carries its proof.
