E-commerce and retail software development

JasperByte builds e-commerce and retail software for Canadian businesses: custom storefronts, Stripe checkout flows, inventory and fulfilment systems, and the automation that connects a store to the warehouse, the accounting system, and the customer’s inbox.

What we build for e-commerce & retail

  • Custom storefrontsFast, accessible shopping experiences where an off-the-shelf platform cannot express your catalogue or pricing.
  • Checkout and paymentsStripe integration built for conversion and correctness — saved cards, taxes, discounts, and failed-payment recovery.
  • Inventory and fulfilmentStock accuracy across channels and locations, with picking and shipping workflows that match your warehouse.
  • Platform integrationsShopify, marketplaces, ERP, and accounting systems connected so orders and stock stay in step.
  • Customer automationAbandoned cart, post-purchase, and support flows, including AI agents that answer order questions with real data.

What makes this sector different

Retail lives with seasonal spikes. A system that is comfortable in September needs to survive a Black Friday that is ten times the load, and the failure mode is losing sales during the only hours that really matter. We load-test against realistic peaks and design caching and queueing so the checkout path degrades gracefully rather than falling over.

Inventory accuracy is the other recurring problem. Selling stock you do not have costs you a customer; hiding stock you do have costs you a sale. Multi-channel businesses need a single source of truth with clear rules about reservation and oversell, and that is a design decision, not a setting.

Canadian retail also means provincial tax rules, cross-border shipping and duties, and customers who expect to see prices in CAD. These are unglamorous details that cause real support load when they are wrong.

FAQ

E-commerce & Retail questions we get asked.

Should we use Shopify or build custom?

Shopify is the right answer for most retailers, and we will say so. Custom becomes worthwhile when your catalogue, pricing logic, or fulfilment model genuinely does not fit the platform — configurable products, B2B pricing tiers, or complex multi-location inventory. Often the best answer is Shopify for the storefront with custom systems behind it.

Can you handle our Black Friday traffic?

That is a design and testing question, not a hosting one. We load-test against your expected peak, put caching and queues in front of the paths that matter, and make sure checkout stays available even if something less critical degrades.

Can you sync inventory across multiple sales channels?

Yes. The important part is agreeing the rules first — which channel reserves stock, how oversell is handled, and how quickly counts propagate. We design that explicitly rather than letting whichever system writes last win.

Do you handle Canadian sales tax?

Yes — GST, PST, and HST vary by province and it is a common source of quiet errors. We integrate tax calculation properly rather than hard-coding rates that go stale.
