# Spend management

Spend management is how a company controls and tracks its spending across the business, from procurement and supplier contracts to employee expenses like travel, using set rules, tools and spending data.

Also called: business spend management, BSM

## What is spend management?

Spend management is the set of rules, tools and data a company uses to decide and see where its money goes. This cheat sheet covers how to think about it and how to bring it to business travel. The detail is further down.

### How to think about it

- **It's wider than expense management.** Expense management usually tracks individual employee expenses, like meals or taxis. Spend management also covers procurement, supplier relationships, budgeting and compliance.
- **It runs day to day.** A traditional budget sets spending limits. Spend management uses real-time data to watch where money goes throughout the year, not just at planning time or during audits.
- **Four areas.** Procurement, employee expense management, budget tracking and compliance with financial rules and audits.
- **Rules before the spend.** A policy checked at booking stops an exception before it happens. A post-trip review only finds it after the money is spent.

### Bringing spend management to business travel

1. **Audit what you have.** Review the travel policy, approval workflows and reimbursement process for gaps or unclear rules that lead to overspending.
2. **Get real-time visibility.** Use software that shows travel spend as it happens, flags out-of-policy spending and simplifies reconciliation for finance.
3. **Name a team.** Give a cross-functional group the job of overseeing travel spend, enforcing policy and spotting trends.
4. **Review on a schedule.** Look at travel spend data on a regular cadence, gather traveler feedback and refine the strategy.

## Questions

### What is the difference between spend management and expense management?

Expense management usually focuses on tracking individual employee expenses, like meals or taxis. Spend management takes in procurement, supplier relationships, budgeting and compliance as well.

### What is spend under management?

In federal procurement, bringing spending under management means moving it under smart buying practices, such as strong strategic oversight and collecting and sharing data on terms, conditions, performance and prices paid. The President's Management Agenda directs agencies to reduce unaligned spending by bringing it under management.

### How is spend management different from budgeting?

A budget sets spending limits. Spend management uses real-time data to monitor spending across departments day to day, so teams can adjust before problems arise.

### Is spend management only for large companies?

No. Small teams use spend tools for tighter control over cash flow, less manual invoice processing and automated purchase orders.
