Questions & Answers

Frequently Asked Questions

When should an enterprise choose Shopify Plus over WooCommerce?

Shopify Plus is the premier option for fast-growing omnichannel retailers seeking a fully managed, PCI-DSS Level 1 compliant infrastructure that handles high flash-sale volumes without dedicated server administration. WooCommerce is best when an organization requires complete database ownership, complex custom calculation logic, private sovereign Canadian hosting, or bespoke on-premises ERP integration.

How do you prevent stock overselling between warehouse and web?

We architect bi-directional middleware using resilient webhooks and message queues. When an order is placed on Shopify or in a physical warehouse via Zebra RFID barcode scanners, stock levels decrement across all channels immediately with automated safety buffers.

Can our existing customer accounts and passwords be migrated?

Yes. We extract historical order transactions, customer records, and addresses. Because passwords use secure cryptographic one-way hashing, we implement automated white-label account activation flows that allow customers to re-authenticate with a single click.

How do you handle multi-currency and Canadian provincial sales taxes (HST/PST/QST)?

Our ecommerce architectures include automated geo-IP currency detection (CAD/USD/EUR) and native integration with Canadian tax rules, automatically calculating HST, GST, and provincial PST/QST rates based on destination shipping address to ensure full CRA compliance.
