Dispensary POS comparison 2026: Dutchie vs Treez vs Flowhub vs Cova vs BLAZE, judged on what an operations team actually needs

Method. We integrate with all five systems and do not sell a POS, so this page has no product to favour. Every row is from the vendor's own documentation, help center or public statement, or from G2 as of the date above; where a vendor's documentation is private we say "not documented" rather than guess. Share-of-market figures are from Cannabiz Media's 2024 report (latest public). G2 counts change daily. Corrections: hello@budally.com — we'll update the row and the review date.

Who this is for

Owners and GMs choosing a first POS, operators who inherited two or three systems through acquisition, and anyone being told "you'll need to switch POS to get that." The last group usually doesn't.

The one-table version

How to read it

If you need to read everything — sales with package IDs, lab results, customers, discounts — Dutchie's API is the broadest, and its scale means every third-party tool supports it. The cost is latency (polling only) and no write path for prices or products: price changes become tasks for your staff.

If you need to write back — inject online orders, push a price change, create a discount — Treez and BLAZE have the surfaces, and both fire webhooks so a layer on top can react rather than poll. Treez's developer terms are the strictest about what a partner may build; read them before you build anything that looks like a competing product.

If you need a clean order model — separate orders, completed orders and refunds — Cova's is the tidiest for accounting. No webhooks, so expect a sync delay.

If you want to point an AI agent at the register — Flowhub and Dutchie now expose MCP servers; Treez sells Winston on top of its own data. None of these are POS-neutral: each agent sees its own vendor's data.

If you're in New Mexico — as of September 2026 only Dutchie, Flowhub, GrowFlow and Leafnet publish live NMS2S support; the retail API covers sales and voids, and the expanded API (Sept 30, 2026) adds inventory reads, splits and adjustments only to integrators who pass CCD validation — ask your POS which tier it has; room moves, transfers and tax entry). Details in the NMS2S guide.

What none of them do (and what that means for you)

• Publish a price. Ask for the contract, the per-store rate, the integration fees (BLAZE charges for API access), the payment-processing terms and the exit terms before the demo, not after.
• Expose your cash drawer. Till sessions and over/short are not in any of the five APIs (POSaBIT is the exception). Cash reconciliation has to come from Metrc receipts plus your processor.
• Expose timeclock. Labor-to-sales needs a payroll or scheduling source.
• Carry your loyalty balances out. Points live in the POS; a switch means an export, a crosswalk and, for consent, proof. The switch guide covers what survives.
• Reconcile to Metrc across vendors. Each has a Metrc view of its own data; none sees an acquired store running a different POS.

Deciding

1. Register first. Uptime history (ask for the 4/20 incident log), hardware, checkout time, payment partners allowed.
2. Data second. Can you get your own sales with package tags out daily, by API or export? If the answer is "only in reports", keep looking.
3. Writes third. Only matters if you'll inject orders or push prices. If not, don't pay for it.
4. Terms fourth. Who owns the customer record, what can't a partner build, what happens to the data at exit.
5. Operations layer separately. Reconciliation, invoice capture, pricing, loyalty gap, close — these don't need to live in the register, and if they don't, the POS decision stops being a ten-year marriage.
