You didn't overspend on product. You lost money on the process.

$2,450 vanished from your operation last month.

Not from vendor markups. Not from employee theft. Not even from market volatility.

It disappeared through the cracks of your broken purchasing system.

"Just grab some gloves and cones with your card. We'll figure out the paperwork later."

This sentence is costing you thousands.

Someone makes a quick purchase on their personal card.

No purchase order.

No approval routing.

No visibility.

Finance discovers it when the statement arrives—after month-end close.

Meanwhile, that same inventory sits unused at your other location.

The Hard Truth: This Isn't About Your Vendors

Your suppliers are doing exactly what you asked.

The real problem?

Your team is scattered across 3 retail locations and 2 cultivation sites, all buying what they need however they can:

  • Emergency one-off purchases
  • Decentralized ordering
  • Zero spend visibility
  • No standardized process

And at the end of the month, Finance is left hunting down receipts and coding expenses that should have been tracked from day one.

That's not just frustrating. It's bleeding your margins dry.
