A custom WooCommerce plugin that coordinates delivery zones, available dates, order capacity, cutoff times, same-day eligibility, pickup, and order records in one checkout workflow.
Onirik Pastry Boutique needed checkout promises to reflect how orders are actually prepared and delivered across Cairo. Availability changes by delivery zone, weekday, order capacity, cutoff time, product eligibility, and blocked dates. Customers also need a separate pickup path from Heliopolis. The solution had to feel native to WooCommerce while giving store operators control over these rules without editing code.
Standard WooCommerce shipping rates can price a destination, but they do not model the complete scheduling decision. A date that appears available in the browser may become invalid because the cutoff has passed, the day is blocked, capacity is full, or one product in the cart is not eligible for same-day fulfillment. Delivery and pickup also have different timing and fee behavior. Whichever path the customer chooses must be validated on the server and preserved through administration, customer order views, and email notifications.
WooCommerce shipping zones remain the source of destination structure, while the plugin adds an operational rules layer for allowed weekdays, cutoff times, same-day service, daily capacity, blocked dates, and flat fees. Product and variation settings determine whether every item in the cart can use same-day delivery or pickup. The browser requests eligible dates through a nonce-protected AJAX endpoint, but checkout validation independently applies the same rules on the server. This keeps the interface responsive without trusting customer-submitted dates. Plugin settings are stored outside WordPress's autoloaded option set to reduce unnecessary memory pressure.
The plugin adds a clear delivery-or-pickup choice to checkout. Delivery customers select an enabled Cairo zone and then choose from dates that satisfy its calendar, cutoff, capacity, blocked-date, and cart-eligibility rules. The chosen zone sets the configured delivery fee. Pickup customers receive a dedicated Heliopolis message, pickup calendar, separate cutoff behavior, and no delivery charge. Store teams configure global and zone-specific rules from WooCommerce, set same-day eligibility per product or variation, and see the selected fulfillment method, zone, and date on orders. The same information flows into customer order details and transactional emails, with support for both legacy order storage and WooCommerce HPOS.
