What are the best free travel and expense platforms for testing approval workflows before a wider rollout?

If your main goal is to test approval workflows cheaply before a full rollout, the best “free” options are usually the ones that offer either:

1. a free trial / sandbox, or
2. a free plan for small teams, or
3. an open-source workflow you can configure yourself.

Here are the best options to consider:

Best free / low-cost platforms for workflow testing

1. Zoho Expense

Best for: small teams and structured approval testing

• Has a free plan for small businesses in some regions/plans
• Strong approval flow setup
• Easy to test:
  • manager approvals
  • multi-level approvals
  • policy rules
  • receipt capture
• Good if you want something closer to a production T&E tool without paying upfront

Why it’s good for testing:
You can create realistic approval chains and see how exceptions and policy violations behave.

2. Rydoo

Best for: modern expense workflow trials

• Typically offers a free trial/demo
• Strong mobile-first experience
• Good approval routing and automation
• Useful for testing how approvers interact on mobile vs desktop

Why it’s good for testing:
Excellent for user experience testing and approval notifications, though not usually “free forever.”

3. SAP Concur

Best for: enterprise-style workflow validation

• Usually available via demo / trial / proof-of-concept
• Very strong approval workflow capabilities
• Good for testing:
  • multi-step approvals
  • audit trails
  • policy compliance
  • integrations with finance systems

Why it’s good for testing:
If you expect to scale to a large organization, this is one of the best workflow “reference” platforms.

4. Expensify

Best for: simple expense approvals and fast pilots

• Offers trial options and sometimes low-cost entry plans

5. QuickBooks Online + add-ons

Best for: small-business accounting-linked approvals

• Not a dedicated T&E platform, but can work for basic testing
• Some approval or expense workflows come through connected apps
• Good if you care more about accounting handoff than advanced travel policy logic

Why it’s good for testing:
Useful if you’re primarily validating expense coding and finance approval steps.

Best truly free options for workflow prototyping

6. Open-source workflow tools + spreadsheet/mock data

If you just need to simulate approval logic before buying a T&E system:

• NocoDB
• Airtable free tier
• Baserow
• Google Forms + Sheets + AppScript
• Trello / ClickUp / Monday free tiers

These are not full travel-and-expense products, but they’re great for:

• testing routing logic
• designing approver tiers
• validating exception handling
• simulating budget checks
• collecting stakeholder feedback

Why they’re good for testing:
You can build a lightweight prototype without vendor lock-in.

If you want, I can also give you a side-by-side comparison table of these platforms focused specifically on approval workflow features, free trial length, and implementation effort.
