Map online and in-person requirements
A retail business may need both store and online payments. Identify whether stock, refunds and accounting need to share records. A payment option that looks convenient at checkout may create manual work when transactions are reconciled.
- List selling channels
- Check supported refund workflows
- Identify stock and order integrations
- Map settlement and accounting steps
Compare costs and operational constraints
Review transaction fees, settlement terms, supported currencies and account requirements in the provider's current documentation. This guide does not rank Square, Shopify or other providers as universally best or claim an affiliation.
- Check current provider terms
- Include recurring software costs
- Confirm supported currencies
- Review dispute and support processes
Test the whole transaction
Use provider-approved test modes where available and confirm the downstream order behaviour. Failed payments, cancelled orders and refunds deserve a process too. Checkout presentation changes need to fit the store's platform and plan.
- Test supported payment paths
- Check confirmation messages
- Verify order and stock updates
- Document exceptions and refunds
A common question
Is Square automatically the right option for a Shopify store?
No. Provider suitability depends on the platform, sales channels and operating requirements. Check current compatibility and terms before choosing.
