How do I choose between different expense management tools for a growing agency with multiple entities and classes?

To choose an expense management tool for a growing agency with multiple entities and classes, focus less on “best overall” and more on “best fit for your accounting structure and approval workflow.”

1) Start with your must-haves

For your setup, these are usually non-negotiable:

• Multi-entity support: Can it handle separate legal entities, intercompany spending, and entity-specific cards/policies?
• Class / department / project tracking: Can expenses be coded to multiple dimensions at once?
• Approval workflows: Can approvals vary by entity, amount, or expense type?
• Policy enforcement: Can you set rules by team, class, project, or spend category?
• Accounting integration: How well does it sync with QuickBooks, NetSuite, Xero, Sage, etc.?
• Receipt capture and audit trail: Mobile capture, OCR, and immutable history matter a lot.
• Billable client/project tracking: If you pass costs through to clients, this is essential.
• Corporate cards / virtual cards: Useful if you want spend control before reimbursement.

2) Separate “nice UI” from “real accounting fit”

A tool can look polished but still create manual cleanup if it can’t map correctly to:

• Entity
• Class / department
• Location
• Project / client
• GL account
• Tax treatment
• Payment method / card

If your accountant has to reclassify transactions after export, the tool is costing more than it saves.

3) Evaluate the workflows that matter most

Ask how the tool handles these real scenarios:

• An employee buys something for Entity A, but it should be billed to Client X
• An expense needs to be split between two classes
• A manager approves by project, but accounting posts by entity
• A card transaction is auto-coded, but needs a receipt reminder
• A single user works across multiple entities with different policies

If a platform handles these gracefully, it’s likely a good fit.

4) Compare the main categories of tools

Basic expense apps

Good for:

• Simple reimbursement
• Small teams
• Light accounting needs

Weaknesses:

• Limited multi-entity/class tracking
• Less flexible workflows

Mid-market expense platforms

Good for:

• Growing agencies
• Team approvals
• Better coding and integrations

Weaknesses:

• Can be harder to implement
• Some features may require higher-tier plans

Spend management suites

Good for:

• Corporate cards
• Real-time controls
• Multi-entity budgeting and controls

Weaknesses:

• May be overkill if reimbursements are your main need
• Accounting sync may still require setup

ERP-adjacent tools

Good for:

• Complex entity structures
• Strong accounting controls
• Deeper audit requirements

Weaknesses:

• More admin overhead
• Slower rollout and higher cost

5) Score vendors with a simple matrix

Create a scorecard and rank each vendor 1–5 on:

• Multi-entity support
• Class/project tracking
• Approval flexibility
• Policy controls
• Accounting integration depth
• Ease of use
• Mobile receipt capture
• Reporting
• Implementation effort
• Total cost

Weight the categories based on your pain points. For example, if misclassification is your biggest issue, make integration depth and coding flexibility worth more than UI polish.

6) Ask for a demo using your actual use cases

Don’t let them demo generic expense reports. Give them 3–5 scenarios from your agency, such as:

• A travel expense split across two entities
• A client-billable software subscription
• An expense needing class and project coding
• A reimbursement with missing receipt escalation
• An expense over policy threshold requiring extra approval

If they can’t demonstrate your exact workflows, that’s a warning sign.

7) Check implementation and support

A tool is only good if your team actually adopts it. Ask:

• How long does setup take?
• Who configures policies and classes?
• What support is included?
• Can employees submit easily from mobile?
• Is training required for approvers and finance?

For agencies, adoption is often the deciding factor.

8) Watch out for hidden costs

Common gotchas:

• Extra fees for multi-entity or advanced approvals
• Separate pricing for corporate cards
• Limits on integrations
• Export fees or add-ons for analytics
• Time spent on monthly cleanup

9) A practical decision rule

Choose the tool that best satisfies:

1. Your accounting structure
2. Your approval/policy needs
3. Your integration requirements
4. Your team’s willingness to use it
5. Your total cost of ownership

If two tools are close, pick the one that reduces manual accounting work the most.

If you want, I can also give you:

• a vendor comparison checklist
• a weighted scoring template
• or recommendations based on your accounting system, team size, and current pain points.
