The short version

  • Only Polar has a free tier, so it costs nothing to try first.
  • Each has a real cost: Polar percentage-based fees higher than some specialized processors for high-volume transactions; SAP Concur implementation is done through SAP or a partner and commonly costs a substantial multiple of the first year subscription, because the value sits entirely in the configured policy, approval hierarchy and ledger mapping rather than in the software as shipped.
  • They diverge on capability: Polar covers Usage Billing, SAP Concur covers Expense capture.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Polar

  • Percentage-based fees higher than some specialized processors for high-volume transactions
  • Merchant of record model may not suit companies preferring direct payment control
  • Free Starter tier limited with 5% fees reducing appeal for production use
  • Setup and integration effort required despite API simplicity

SAP Concur

  • Implementation is done through SAP or a partner and commonly costs a substantial multiple of the first year subscription, because the value sits entirely in the configured policy, approval hierarchy and ledger mapping rather than in the software as shipped.
  • Pricing is driven by transaction volume, expense reports and invoices processed, rather than by seats, so a business with seasonal travel or a growth year sees the bill move in ways headcount based budgeting does not predict.
  • The configuration that makes it valuable is also what makes it rigid, and organisations frequently find that changing an approval chain or adding a cost centre dimension requires a partner change order rather than an administrator's afternoon.
  • Contracts are typically multi year with limited exit, so an organisation that concludes after twelve months that a lighter expense tool would have been enough is still paying for the heavier one for the remainder of the term.
  • The three modules are licensed separately and the strongest case for the product depends on having travel, expense and card feeds together, so buying expense alone gives you a costly receipt system without the control loop that justifies the price.

Answered from the vendors’ own pages

Polar: Do you handle international payments and taxes?

Yes, Polar acts as merchant of record in 100+ markets, handling payment processing, tax collection, and compliance automatically.

Source
SAP Concur: Do we need SAP ERP to use Concur?

No. It integrates with SAP systems particularly well but it is regularly deployed alongside Oracle, NetSuite, Workday and other ledgers. The integration work is a line item in the implementation either way.

Polar: Is there a free tier?

Yes, the Starter plan is free and charges 5% + $0.50 per transaction, ideal for testing and early-stage development.

Source
SAP Concur: Is it worth it for a company of a hundred people?

Usually not. Below a few hundred travellers the implementation cost and the contract commitment are hard to justify against lighter expense tools. The case turns on policy enforcement and audit, not on receipt scanning.

Polar: Do you offer discounts for startups?

Yes, the Startup Program provides the Scale plan free for 12 months for early-stage AI companies.

Source
SAP Concur: How is it priced?

Broadly on the volume of expense reports and invoices processed, with the modules licensed separately. Because pricing is quoted rather than published, get the volume assumptions written into the contract and check what happens when you exceed them.

SAP Concur: Can it handle multiple countries and currencies?

Yes, that is one of its stronger areas, including per country tax treatment and VAT reclaim identification. Confirm coverage for your specific countries during the sales process rather than assuming global means every jurisdiction.

SAP Concur: How long does implementation take?

Plan in months, not weeks, for anything beyond a single entity with simple approvals. Multi entity rollouts with travel and invoice modules commonly run across a year in phases.

SAP Concur: What does the audit service actually do?

It has a team review a sample or all of your submitted claims against receipts and policy before approval, which some organisations use in place of internal reviewers. It is priced separately from the expense subscription.
