The re-launch of the Nectar Business brand gives businesses more ways to spend points through an enhanced "rewards for business" section and regular special offers.
Points can be redeemed for new office equipment, including Sat Navs and Bluetooth headsets, a team adventure day out or individual rewards such as a luxurious spa weekend.
Every month special offers will be available for a limited period of time. This month the offers include 25% off champagne and chocolates, 25% off laptops and 50% off magazine subscriptions.
The redesigned has been given a fun, upbeat feel with easier navigation and more information on all Nectar Business sponsors.
Collectors can log onto a personalised My Nectar Business section to view their points statement, access a points calculator, find recently viewed rewards and spend their points.
All customers will receive a re-designed Nectar Business card and can use their card to earn points through both Nectar Business sponsors and through Nectar sponsors such as Sainsbury, Debenhams and BP when they buy personal items.
Charlie Humphreys, head of Nectar Business, said: "Nectar Business is moving in a new and exciting direction. We have spent a lot of time putting together innovative, desirable rewards and treats that reflect our collectors' needs and ultimately acknowledge our customers' loyalty to the programme."
Nectar Business sponsors include Viking Direct, EDF Energy, Hertz and Thomson Local, among others.
Earlier this month, Nectar operator Loyalty Management Group was sold to Canadian rival Aeroplan for a reported £368m, with founder Sir Keith Mills picking up £160m from the sale.
