We’re building a mini-ERP that runs directly
within your spreadsheet.

Implementing an ERP system can be a daunting task for any business. It requires a significant investment of time, resources, and often necessitates a complete overhaul of existing processes. For small and medium-sized businesses, this can be especially challenging.

That's why they turn to spreadsheets. Spreadsheets are a familiar and trusted tool for many businesses. They're flexible, powerful, easy to use and cheap.

Mellow understands the value of spreadsheets and has no intention of persuading you to abandon them. Instead, Mellow aims to make them even better by giving them the powers of a mini-ERP.

We're starting with e-commerce merchants first and will slowly expand to supporting brick-and-mortar businesses as well.
