Octolize Box Packing

Octolize Box Packing (formerly Flexible Shipping Box Packing) is an essential logisitics extension designed to optimize cart packaging and shipping costs for WooCommerce stores. By taking into account the exact length, width, height, weight, and maximum volume of every item in a customer's shopping cart, the plugin calculates how to fit products into pre-defined shipping boxes using an advanced 3D box packing algorithm. It seamlessly communicates accurate box dimensions and weights to live shipping carrier APIs (such as DPD, DHL, FedEx, UPS, and USPS), ensuring customers are charged precise shipping fees at checkout. Furthermore, warehouse staff benefit from clear packing instructions on order edit screens, reducing material waste and preventing shipping cost discrepancies.

Main Features

• Advanced 3D box packing algorithm — Calculates 3D product dimensions, volume, and weights to determine the exact number and size of boxes required for an order.
• Custom box configuration — Set up unlimited custom boxes, padded envelopes, and cartons with inner/outer dimensions, empty box weights, and max payload limits.
• Integration with carrier shipping plugins — Seamlessly passes calculated packed box data directly to shipping integration plugins (UPS, FedEx, DHL, DPD, USPS) for accurate live rate API queries.
• Packing method choices — Support for multiple packing logic options, including packing items into custom boxes, individual product packing, or falling back to weight-based estimates.
• Order packing preview & instructions — View visual box contents and detailed item placement summaries directly inside WooCommerce order admin screens.
• Padding & margin adjustments — Define internal protective padding allowances to accommodate bubble wrap, styrofoam, or box wall thickness.
