From spreadsheets to Katana

When did spreadsheets start slowing you down?

When you’re selling across multiple channels and locations, spreadsheets can’t do the job. Get live stock control that works with your existing tools and switch over in a few short weeks.

Should you be on spreadsheets?

If you’re a growing product business, the answer is: likely not. 
Spreadsheets are a natural starting point for inventory management, but they don’t scale. As the number of sales channels and inventory locations grow, so does ops complexity – which doesn’t pair well with manual updates. 

Multi-location inventory requires real-time updates across warehouses, and multichannel selling requires every platform to see the same stock numbers at the same moment. Spreadsheets punish you for growth: manual work compounds, and the more you grow, the bigger the lag between your numbers and reality. 

Out-of-sync inventory costs you twice: first in stockouts and overstock, then in manual labor. 

Spreadsheets can’t keep up with the pace of orders, so by the time the data is processed, it’s often outdated. You oversell out-of-stock items or miss potential sales, then waste hours manually reconciling spreadsheets. 

The real-time inventory alternative to spreadsheets

Katana solves stockouts and overstocks through real-time inventory control built for multichannel businesses, without any of the ERP overhead.

Keep stock and orders in sync as you grow

Katana replaces spreadsheet inventory tracking with a live system that updates as work happens. When an order is confirmed or stock is received, inventory adjusts in the same place your team manages it. The number you see reflects current availability.

  • Stock by location
  • Committed vs. available visibility
  • Order-based allocation
  • Demand-driven purchasing

Forecast demand with live inventory data

Katana helps teams plan ahead by combining live sales signals with current stock levels. You can forecast demand using historical and real-time data, and use that to plan replenishment before stock runs low.

  • Replenishment planning
  • Reorder points
  • Demand visibility
  • Production scheduling

Moving away from spreadsheets couldn’t be easier  

Fear not: switching from spreadsheets to Katana isn’t a long project. Many teams are set up and live in as little as six weeks with guided onboarding. You’ll have a clear plan with regular check-ins, and help from a real person throughout.

Step 1: Import your spreadsheet

First, bring your existing spreadsheet. Katana’s team helps you import all relevant data –  products and materials; stock levels by location; suppliers; open orders and more. 
 

During setup, your onboarding manager helps you spot duplicates, naming issues, and unit mismatches. Review everything before it goes live – nothing gets finalized without your approval.

Step 2: Connect your channels and tools

Next, connect the tools you rely on – for example Shopify, WooCommerce, and QuickBooks. 
 

In live calls, your onboarding manager helps you set up Katana around how your team runs orders today. You’ll confirm how sales orders should flow into fulfillment or production, and check that stock updates correctly across channels and locations. 
Katana adapts to your business and processes, making the transition as smooth and easy as possible.  

Step 3: Go live

Before launch, test that orders and stock behave as expected. Confirm opening stock levels by location, check that integrations sync correctly, and make sure your team knows where to find the numbers they need. 

Once you switch over, your onboarding manager stays available with check-ins at 30 and 45 days. After that, a Customer Success Manager takes over for ongoing support and helps you access resources like Katana Academy as needed.
