From Spreadsheets to Seamless Procurement: Theory's Story

You know the feeling.

You open your procurement spreadsheet. Cells are mysteriously blank. Orders placed without approvals. Duplicate shipments arriving at different sites on the same day.

Suddenly, your “simple” spreadsheet is your worst enemy.

For Theory Cannabis, a rapidly expanding cannabis operator, this wasn’t occasional—it was daily. They were juggling more than 10 QuickBooks files, manual reconciliations, rogue credit card spending, and endless Google Sheet chaos .

The Breaking Point

Every operation hits the moment where staying the same hurts more than changing. For Theory, seeing their procurement spreadsheet actively block growth was that exact moment. They needed:

  • Real-time visibility across all locations
  • Strong, clear approval processes
  • An end to duplicate orders
  • Simplified month-end reconciliations  

And crucially, a solution built specifically for cannabis operations.

Enter MainStem

MainStem’s procurement platform eliminated Theory’s spreadsheet nightmares practically overnight:

  • Edits never vanished again—data integrity restored
  • Approvals enforced BEFORE spending
  • Real-time visibility across all purchasing activities
  • Month-end transformed from chaos to clarity

Implementation was quick—just 28 days with zero downtime, including full integration into Theory’s existing QuickBooks and ERP systems .

With MainStem, Theory Cannabis didn’t just stop spreadsheet chaos—they began to:

  • See spending trends clearly across sites
  • Consolidate vendors and maximize savings
  • Make strategic, data-driven inventory decisions

Amber Cook, Senior Manager at Theory Cannabis, sums it up best:

MainStem is the gold standard of Cannabis Enterprise Procurement Software” .

Hard Truth: Spreadsheets Have Limits

The spreadsheets that got you here won’t get you there. They don’t scale. They actively work against you.

Ask yourself:

  • How many hours each week do you waste in procurement spreadsheets?  
  • Can you see—right now—what every location orders?
  • How often do duplicate or unapproved purchases slip through?
  • Is your month-end reconciliation a nightmare?

If these questions hurt, you’re exactly where Theory was.
