Turn your store into a B2B channel without leaving OpenCart. An "Add to Quote" button appears on every product page, shoppers collect the items they need in a session quote list, adjust quantities and send you their company details and notes. Each request lands in a dedicated admin screen where you set the unit price per line, choose how many days the quote stays valid, add a note and e-mail it. The customer's quote e-mail carries a one-time accept link; following it rebuilds their cart with your quoted prices already applied, using OpenCart's own per-line cart price override — no order-total hacks and no core file edits. Status flows pending to quoted to accepted or expired, with a token guarded cron URL that sweeps overdue quotes. English and Turkish admin translations included.
