Building for retail means building for peaks
The catalog has one owner, and it is rarely the website
In most retail businesses the POS or ERP already holds products, costs and stock. Problems start when the website becomes a second place to edit them. Before any build we agree a field-by-field ownership table: the ERP owns SKU, cost, tax class and stock, the store owns descriptions, images and SEO text, and nothing is edited on the wrong side. Sync then becomes predictable. Stock changes arrive by webhook where the system can send them and by short-interval polling where it cannot, and every push is idempotent so a retry never creates a duplicate order in the warehouse.
Overselling is a design decision
No sync is instant, so we decide in advance what happens in the gap. Options include a safety buffer per product, reserving stock when an item enters checkout, or accepting backorders on lines the supplier restocks quickly. Fast-moving sale items usually get a buffer and a reservation. Slow lines need neither. What matters is that the rule is chosen by you, written down and tested, not discovered on the busiest day of the year.
Rehearsing the sale
A retail calendar has dates you can see coming: seasonal sales, product drops, the weeks before major holidays. We schedule a code freeze ahead of each one and run a load test that copies real behavior, with visitors browsing, adding to cart and paying, because carts and checkout cannot be served from a page cache. Typical fixes are moving order emails and stock pushes into background queues, trimming cart-fragment requests, indexing the order tables and making sure payment webhooks are processed even if the customer closes the tab. Our performance optimization team does the same job for stores we did not build.
Payments, tax and customer data
We keep card numbers off your server by using the gateway's hosted fields or redirect, which keeps your PCI DSS obligations as small as they can be. Tax is calculated by a rules engine or a tax service, not hard-coded, since rates and thresholds change. Customer accounts, addresses and order history are personal data, so consent, export and deletion requests are handled inside the store. If you sell into regions with specific privacy or accessibility rules, name them and they become requirements we build and test to.
Picking the platform
WooCommerce suits most catalogs and gives your team a familiar admin. A custom Laravel store earns its cost when pricing is contract-based, the product is configurable in ways plugins fight, or order volume needs its own data model. We will say which one we would choose and why before you commit to either.
