About the Company

SupplierPlus is a Supply Chain Financing (SCF) platform that helps Corporate Buyers leverage their supply chains while improving their Suppliers’ access to working capital. We do this by financing the approved purchase invoices of the Corporate Buyers, which allows Suppliers to cash their sales invoice immediately. The financing is provided by Creditors such as banks, who are interested in acquiring invoices that Suppliers have issued against the Corporates. Ultimately, SupplierPlus ensures that companies of all sizes have easy and fairly priced access to working capital.
We are currently 21 employees altogether and 4 are in the development team.

SupplierPlus is a turn-key SCF platform that caters to three parties - large Corporates as Buyers, their Suppliers, and Banks who provide the necessary capital. The solution provides efficiencies through clever workflows and high degrees of automation between the SupplierPlus web application, enterprise ERPs and banking systems. One of the solution’s key differentiators is the speed and ease of implementation relative to competitors. This decreases our time-to-wow.
