Case Study
Supporting a Multi-Account, Million-SKU Operation Through Custom Integration and Long-Term Collaboration
Posterazzi Corp has been our customer for many years. The company is led by a smart and knowledgeable owner, and they operate multiple accounts with us.
Their integration is complex and highly customized. One of the most interesting aspects of working with Posterazzi is the scale—they manage millions of SKUs, which has been a great challenge and opportunity for our engineering team to support and adapt to.
We’ve grown together over the years, and I look forward to continuing our partnership for a long time.
Daniel Sodkiewicz
GeekSeller Co-founder
Our company loves the user friendly interface that allows us to process and fulfill our orders and inventory with multiple online marketplaces. We love the vast selection of online marketplace integrations and the highly dependable and reliable customer support that GeekSeller offers.
Our experience with GeekSeller has been top notch since our first demo. The initial setup and integration process with GeekSeller was simple and very well structured, including the training sessions. GeekSeller Support is always available to us which was very important to our users. I highly recommend GeekSeller for a company’s multichannel marketplace online presence.
There has been nothing so far that we do not like with GeekSeller. The team at GeekSeller has changed the way we operate our business.
