    A wedding registry company wasn't satisfied with its developers and needed to get its website out of beta quickly. Bilberrry built a custom PHP website and updated the old website. The new website has a feature that syncs with large national retailers to provide registry information. Bilberry now maintains and updates both websites. 

    "Other developers we’ve seen have said they could build something, but never completed it, giving us 'maybes' or reasons why they shouldn’t be building it. That’s never happened with Bilberrry." – CEO, Wedding Registry Company
