I talk to dispensary owners every week. When I ask them what they spend on vendor costs, most of them know their COGS number and that's about it. They can tell me they spent $1.1 million on inventory last year, but they can't tell me what they spent on the labor to manage those vendors, the fees to pay them, or how much money they left on the table in unclaimed credits.

So I decided to lay it all out. This is a realistic breakdown of what a $2 million per year single-location cannabis dispensary actually spends on vendor-related costs. Not just inventory. Everything.

The Inventory Line: COGS at 50%

Let's start with the obvious one. For most dispensaries, cost of goods sold runs between 48% and 55% of top-line revenue. At $2M/year, that's roughly $1,000,000 going out the door to vendors for flower, concentrates, edibles, pre-rolls, and everything else on your shelves.

This is the number most operators know. It's on their P&L. It's in their POS reports. But here's what they don't always think about: COGS isn't just what you ordered. It's what you ordered minus what you should've gotten back in credits, returns, and adjustments. If you're not tracking those things, your effective COGS is higher than it should be.

AP Labor: The Hidden Headcount

Someone at your shop is managing vendor invoices. Maybe it's you. Maybe it's a bookkeeper. Maybe it's your store manager who's already wearing four other hats. Whoever it is, they're spending time on data entry, matching invoices to POs, cutting checks, chasing discrepancies, and filing paperwork.

For a dispensary doing $2M with 20-30 active vendors, this typically eats 15-25 hours per week. If you're paying someone $22/hour fully loaded, that's roughly $22,000-$28,000 per year in AP labor. And that's assuming they're efficient. Most aren't — because they're doing it in spreadsheets, not a real system.

We built our managed accounts payable service specifically because we saw this cost repeated at every shop we talked to. It's not a technology problem. It's a people problem. Nobody has the time to do AP well.

Payment Processing Costs

Cannabis dispensaries don't get to use normal payment rails for vendor payments. No ACH for most. No standard business credit cards. That means checks, cashier's checks, money orders, or cash — all of which carry costs.

If you're writing 80-120 vendor checks per month (invoices plus partials plus corrections), and each one costs you $3-$8 in bank fees, supplies, and handling time, you're looking at $4,000-$8,000 per year just in payment execution costs. That's before we even talk about the time your team spends at the bank.

This is exactly why we built check payments into ShelfSpace. We print and mail your vendor checks directly from the platform. No bank runs. No cashier's check fees. No manual reconciliation.

Lost Credits and Unclaimed Returns

This is the one that kills me. Every dispensary I've worked with has money sitting on the table that they've never collected. Product returns that were never credited. Expired inventory that the vendor should've eaten. Co-marketing promotions where you discounted product and the vendor never reimbursed the difference.

For a $2M dispensary, the typical unclaimed credit exposure is $30,000-$55,000 per year. That's not a guess — that's based on actual recoveries we've done for our clients. The average dispensary we onboard has never tracked vendor credits in any systematic way. It's all verbal agreements and forgotten emails.

Our credit recovery service exists to capture this money. We pull your POS and METRC data, generate credit memos for every return, expiration, and promo, and then work directly with your vendors to get them approved. You don't do anything — we handle the entire process.

Overpayments and Invoice Errors

Here's one that nobody budgets for because nobody knows it's happening. When you're processing invoices manually — comparing line items to purchase orders, checking unit costs, verifying quantities — errors happen. Vendors overcharge. Quantities don't match. Pricing tiers get applied wrong.

Industry data puts invoice error rates at 1-3% for manual AP processes. On $1M in vendor payments, that's $10,000-$30,000 per year in overpayments that you never catch. Some of these are honest mistakes. Some aren't. Either way, without a system that matches invoices to POs line-by-line, you're paying more than you should.

The Full Picture

Let me add it all up for a $2M/year single-location dispensary:

Total vendor-related costs: $1,066,000-$1,121,000

That means your real vendor cost isn't 50% of revenue. It's closer to 53-56% when you factor in the labor, the payment costs, the lost credits, and the errors. On $2M in revenue, the difference between 50% and 55% is $100,000 per year. That's real money.

How ShelfSpace Cuts Each Line Item

This is what we do. We're not a software platform you log into and figure out yourself. We're a managed service that takes over your entire vendor payment operation.

And if you move your best vendors to consignment, your COGS timing shifts entirely. You stop paying for inventory upfront and start paying only for what sells. That's a massive cash flow improvement on top of everything else.

The Real Question

Every dispensary owner I've talked to knows their margins are tight. What most of them don't realize is how much of that tightness comes from the operational overhead of managing vendors — not from the cost of the product itself.

The product cost is what it is. But the $66,000-$121,000 you're spending on labor, fees, lost credits, and errors? That's fixable. That's what we fix.

ShelfSpace is $1,500/month per location. That's $18,000/year to potentially save $66,000-$121,000. The math isn't complicated.
