A spreadsheet tool that
talks to your online store
Connect your Google Sheets™ to your sales channels & other business software.
Give your spreadsheet the powers of a mini-ERP.
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
eCommerce merchants first and will slowly expand to supporting brick-and-mortar businesses as well.

How do you keep everything in-sync?
1. As part of the on-boarding process, Mellow imports your current spreadsheet data.
2. For any sales channel you connect, Mellow automatically imports inventory items and sales orders.
3. Mellow continuously keeps track of all stock adjustments, and correspondingly updates stock quantities everywhere.
3.1. Stock adjustments include: Outbound sales orders, inbound shipments, and manual adjustments.
Basically, we become the single source of truth for all your sales channels data.
Please note that once you connect a sales channel, their stock quantities will get
override on any stock adjustment, whatever the source.
For instance, suppose you connect both Shopify and Etsy, and you have 100 units of item ABC on hold.
Moments later, a sales order of 10 units arrives from your Shopify store.
Mellow will actively reduce ABC's in-stock quantity to 90, on both Shopify and Etsy!
