Quick answer

What software does a Canadian e-commerce seller need?

A Canadian Shopify or Amazon seller runs on four layers: a business bank account (Venn) with low-cost FX for cross-border sales, a cloud ledger (Xero), a sales-sync tool (Synder) that posts every order, fee, and refund into Xero, and receipt capture (Dext) for supplier bills. Together they make multi-channel payouts reconcile cleanly with the correct GST/HST.

Venn, the business bank

Venn is no-fee Canadian business banking with CAD and USD accounts and low-cost FX, which matters when marketplaces pay out in different currencies. It syncs to Xero so every deposit lands in your books.

Layer 2 · Ledger
Xero 90% off for 6 months

Xero, the ledger

Xero holds your chart of accounts, GST/HST, and reporting. Bank feeds and sales sync post into it and reconcile, so it is the single source of truth for the numbers as you scale.

Layer 3 · Sales sync
Synder Free trial

Synder, the sales sync

Synder connects Stripe, Shopify, Amazon, Square, and PayPal to Xero with per-transaction detail, reconciling payouts, fees, and refunds so multi-channel sales tie out cleanly. It suits higher-volume sellers who need granular records.

Layer 4 · Receipts
Dext 30% off for 12 months

Dext, the receipt capture

Dext captures supplier invoices, inventory bills, and expense receipts by photo, email, or upload and posts them to Xero coded, so your cost of goods and input tax credits are always current.
