Can customers customise products before ordering?

Absolutely! Product customisation increases perceived value and prevents returns. Customisation types include: text input (engraving, personalisation), dropdown selections (handle colour, lens type), checkboxes (add gift wrapping, include instructions), colour pickers (choose custom colour), file uploads (upload logo for printing), conditional options (if gift wrap, ask message), and price adjustments (customisation adds $10). Popular applications: engraved jewellery (add name), custom clothing (choose fabric, buttons), personalised gifts (add message), configured products (build-your-own computer), made-to-order items (custom dimensions), and print-on-demand (upload artwork). Customisation details appear on orders so fulfilment teams see specifications. You set which options are required vs optional. Images can change based on selections (show product in chosen colour). Customised products typically can't be returned unless defective, which customers accept for personalisation. This differentiation is hard for mass retailers to compete with.
