eCommerce Development in Pennsylvania

A variable product has attributes — size, colour, material — and each combination becomes a variation with its own SKU, price, stock level, and image. The complication is combinatorial: four sizes across six colours across three materials is 72 variations to manage. Past a few dozen, the admin becomes slow and the front-end selector becomes hard to use. At that point it's usually better to split into separate products or reduce the attribute set than to push the variation count higher.

Each product page should carry Product structured data with name, image, description, SKU, brand, and an Offer containing price, currency, and availability. Where genuine customer reviews exist, AggregateRating can be included — but only if those reviews are visible on the page, since claiming ratings that aren't shown violates Google's rich-results policy and risks a manual action. Correct Product markup is what makes price and stock status appear directly in search results.

Yes. Products with their titles, descriptions, images, prices, variants, and categories migrate, as do order history and customer accounts. The store is built on a staging URL first so you can check the catalogue product by product before anything goes live. The part that needs planning is URL mapping — platforms structure product and category URLs differently, so every old URL needs a 301 to its new equivalent or the migration costs you the store's existing rankings.

Far less than people expect, provided card details never reach your server. Using a hosted gateway field or redirect — which is how Stripe and PayPal integrate by default — keeps you in the simplest self-assessment category. What you are still responsible for is serving the whole site over HTTPS, keeping WordPress, the theme, and plugins patched, enforcing strong administrator credentials, and restricting who has admin access. Storing card numbers yourself moves you into a dramatically more demanding compliance regime, and there is almost never a reason to.

Shipping can be flat rate, free above a threshold, weight or class based, or live rates pulled from a carrier's API using the customer's address and the parcel's dimensions. Live rates are more accurate but add a request to checkout, so they need caching. Tax in the US means destination-based sales tax across thousands of jurisdictions with economic nexus rules per state — that's normally handled by an automated service rather than manual tax tables, because the rates change constantly.

Core, theme, plugin, and PHP updates applied on staging first; automated off-site backups of both files and the database, tested by actually restoring one; monitoring that checkout still completes after each update, since that's the path that costs money when it breaks; and watching for gateway API changes. A store has a higher maintenance floor than a brochure site because a silent checkout failure is invisible until you notice orders stopped arriving.
