★★★★★

“Our retail store simply couldn't run like it does today without kit builder. Allowing us to reuse the same unique SKU codes infinite times and create unique discounted product kits & sets. Kit builder is a must have for those integrating their e-commerce store to an ERP platform. Easy editing and the option of bulk editing through an Excel spreadsheet makes bulk changes simple.”

“We absolutely love this app and couldn't do without it on both our BigCommerce stores. We started off using it for kits where we have multiple parts - some kits with up to 12-18 components and now are also using it to provide multiple listings on Google that have the same or similar SKU's. It has been a game changer for our business and pricing is reasonable. Kit Builder has a simple design and works well managing inventory for our on-line stores.”
