E-commerce Requirements for Mississauga Retail Brands

Retail in Mississauga ranges from boutique brands near Streetsville and Port Credit to established multi-category merchants who supply stores across the GTA. For many of them, an online store is no longer optional, but "launch a Shopify store" is not a plan. Before anyone opens a design tool, a retail brand should write down its requirements. A good requirements document prevents the two most expensive outcomes in e-commerce: building the wrong thing, and rebuilding it a year later.

Scarlett Digital Studio is a Regina, Saskatchewan studio that works with Canadian retailers remotely; we do not operate a Mississauga office. This checklist reflects what we ask on discovery calls for web development projects with an online store component.

1. Define the business model before the platform

Start with how you sell, not the software. Answer these questions in writing:

• Are you selling only direct to consumers, or also wholesale or B2B accounts with special pricing?
• Do you ship across Canada, to the United States, or internationally?
• Do you offer local pickup from a Mississauga location or warehouse?
• Do you sell physical goods only, or also digital products, gift cards, subscriptions, or made-to-order items?
• Do you also sell in a physical store that needs inventory kept in sync?

Each answer changes the technical requirements. A retailer with a brick-and-mortar location and an online store needs a point-of-sale integration; a made-to-order brand needs lead-time messaging and order-status communication.

2. Catalogue and product data

Your catalogue is the foundation. Poor product data causes more conversion problems than most design flaws. Document:

• SKU structure and how variants (size, colour, material) are modelled.
• Required attributes per category, such as dimensions, care instructions, and ingredients where relevant.
• Photography standards: number of images per product, aspect ratio, and background consistency.
• Bilingual needs: if you sell to Quebec or plan to, French-language requirements may apply to packaging and customer-facing content. The Government of Canada and provincial bodies publish guidance; get proper advice for your category.
• Bulk import path from spreadsheets or an inventory system, so you are not hand-entering hundreds of products.

3. Taxes, shipping, and compliance

Sales tax

Canadian sales tax is not trivial. Ontario retailers typically deal with HST, but rules differ when you ship to other provinces, and registration thresholds apply. The Canada Revenue Agency explains GST/HST obligations at canada.ca. Your store must calculate the correct tax by destination, display it clearly, and produce records your accountant can use. Confirm your obligations with an accountant rather than relying on a plugin default.

Shipping

Decide how rates are calculated: flat, weight-based, carrier-calculated, or free over a threshold. Canada's distances and rural surcharges make shipping a margin issue. Requirements to capture include:

• Carriers you use and whether you want live rates from their APIs.
• Label printing and tracking-number emails.
• Delivery estimates shown at checkout, based on real handling times.
• Rules for oversize, fragile, or restricted items.
• Cross-border documentation if you ship to the US, including duties messaging.

Returns

Write a returns policy first, then build the flow to support it. Include who pays return shipping, the time window, and condition requirements. Make the policy easy to find from product pages and checkout.

4. Payments and security

Customers expect cards, digital wallets, and often "buy now, pay later" options. Choose a reputable payment processor that handles card data on its own secure fields so your store does not store card numbers. The PCI Security Standards Council explains what merchants need to understand at pcisecuritystandards.org. In practice, using a hosted checkout or tokenized fields greatly reduces your compliance burden, but you should still confirm your obligations with your processor.

Also cover: fraud screening settings, handling chargebacks, interac e-Transfer or other Canadian payment preferences if your customers use them, and clear refund handling.

5. Inventory and operations

Overselling is the fastest way to lose a customer. Define how inventory flows between systems:

• Where is the "source of truth" for stock: the store, a POS, or an ERP?
• How often does stock sync, and what happens during sync failures?
• How are backorders, pre-orders, and low-stock thresholds handled?
• Who receives order notifications, and who fulfils them?

Small retailers sometimes underestimate the daily workload. A store with ten orders a day needs a repeatable packing, labelling, and customer-service routine. Write it down. Plan staff time as a real cost.

6. Privacy, accessibility, and legal pages

Your store collects names, addresses, and purchase histories. Under PIPEDA, you need to be open about what you collect and why, obtain appropriate consent, and protect the data. The Office of the Privacy Commissioner provides guidance at priv.gc.ca. If you send marketing emails, Canada's anti-spam law (CASL) requires consent and an unsubscribe mechanism; see fightspam.gc.ca.

Ontario's accessibility rules under the AODA can apply to organizations of a certain size, and accessible design is simply good practice regardless. Aim to meet WCAG guidelines: sufficient colour contrast, keyboard navigation, alt text for product images, and labelled form fields. Review requirements for your organization with a qualified advisor.

Publish clear terms of sale, a privacy policy, shipping information, and returns details. We are not a law firm, so have these reviewed professionally.

7. Search, performance, and analytics

An online store that nobody finds is a warehouse with no door. Requirements should include:

• Clean URLs, unique titles and descriptions, and product schema markup.
• Fast page loads on mobile, since most browsing happens on phones. See web.dev/vitals for Google's guidance.
• Collection pages with useful descriptive copy rather than only a grid of products.
• Analytics that track add-to-cart, checkout steps, and completed purchases.
• A Google Business Profile if you have a physical location customers can visit.

Nobody can guarantee search rankings, and anyone who does should be treated with caution. Strong fundamentals simply improve your chances.

8. Budget and timeline: planning estimates

Retail e-commerce costs vary widely. As a planning estimate only (not a quote), a custom-designed store for a small retailer with a modest catalogue might commonly fall in the low-to-mid five figures in CAD, while a template-based launch can cost less and a store with complex integrations can cost considerably more. Ongoing costs include platform fees, payment processing, apps, hosting, maintenance, and marketing. For platform subscription figures, check the vendor's official pricing page directly, because plans change. Treat our ranges as a starting point for budgeting conversations, and request itemized proposals.

9. Customer accounts, email, and post-purchase experience

Decide whether shoppers must create accounts or can check out as guests; forcing registration commonly adds friction. List the transactional emails you need: order confirmation, shipping notice, delivery follow-up, return updates, and abandoned-cart reminders where consent allows. Write the copy in your brand voice and test each message on mobile. Also plan customer support: who answers questions, through which channel, and within what target time. A store with excellent product pages can still lose repeat buyers through slow, unclear after-sale communication. Include a review process for the first month after launch so you can fix friction points with real order data.

10. A short requirements template

Before you contact any developer, prepare a one-page brief covering: business model, target customers, product count and variants, shipping regions, tax approach, payment methods, required integrations, must-have versus nice-to-have features, launch date, and budget range. Developers can then respond with scoped proposals instead of guesses. You can browse examples of our approach on the work page.
