Challenge
M. Flynn is a Boston jeweller selling engagement rings and custom jewellery in store and online. The shop has to handle products with many variations (size, metal, finish, colour, length), engraving, seasonal promotions and US tax rules – and stay simple for the team that uses it every day.
Solution
We built a custom theme on WooCommerce and developed a set of our own plugins, gathered in a single menu:
- product engraving at checkout
- a promotion engine: dynamic pricing, coupon rules and a free gift with purchase
- “Tax-Free Weekend”: an automatic zero tax rate for qualifying items during a sales tax holiday
- a clear card layout for sets, with all pieces added to the cart in one click
- product and category ordering that is the same in the admin as in the shop
- upsell and cross-sell products on the product page
- export and import of order history, and tools for keeping stock in sync during a point-of-sale system change
- security hardening
Result
The shop team manages promotions, stock and special cases on its own, without a developer. All tools are in one place, each with a description and an on/off switch.
