This guide is for agents quoting hardware for a retail store: boutiques, gift shops, convenience stores, specialty food, hardware stores, dispensary-style counters, anything where the merchant rings up products at a counter and may scan barcodes, print price tags and take cash. For the full catalogue of devices and the rules behind every quote, see Stackably hardware options and bundles (Sunmi).
The short version
Start with a T3. Built-in receipt printer, no separate printer, no network.
Retail almost never needs the Ubiquiti network. Every printer in a retail store sits at the counter and plugs into the terminal by USB. The network is only for a printer placed somewhere a USB cable cannot reach, or a KDS, and a retail store needs neither.
If the merchant prints price tags or barcode labels, quote the label printer. It prints receipts and labels and has a built-in scanner, so it usually replaces a separate scanner too.
If they want a D3 Pro, add a printer by USB beside it: the label printer or a network printer. No Ubiquiti either way.
Small, low-SKU shop with no scanner or drawer: a P3H on its own.
The two builds to quote
Both are T3-based, both are Ubiquiti-free. Pick by what the merchant does at the counter and what they want to spend; the customer-facing option is their preference.
Good | Better | |
Station | T3 | T3 |
Customer-facing / payment | 10.1" CFD (T3 connector) + P2 SmartPad | 11" CPad Pay (T3 connector) |
Receipts and labels | Label printer by USB (receipts, price tags, barcode labels; built-in scanner) | T3's built-in receipt printer. Add the label printer if they print tags. |
Scanner | Built into the label printer. No separate scanner needed. | Handheld scanner with base (Blink 2 if they prefer hands-free) |
Cash drawer | Sunmi MAX or third-party drawer | Sunmi MAX or third-party drawer |
Ubiquiti network | Not required | Not required |
Best for | Stores that print their own price tags or barcodes; budget-conscious merchants; counters where the card reader needs to sit lower or to one side of the station | Stores with pre-barcoded stock; merchants who want the single clean unit with the big customer screen |
Upsell for either build: a P3H as a second device for the shop floor or line busting. Offer it; do not put it on the quote by default.
Small shop: P3H only
A boutique or low-SKU shop that does not scan barcodes, does not print tags and does not need a cash drawer gets a P3H on its own. It prints receipts, takes every payment type, and runs the full Stackably app. The moment the merchant asks for a scanner, a drawer or a label printer, step up to a P3 MIX (which takes all three) or go to the T3 builds above. The P3H takes no accessories.
When a retail merchant wants the D3 Pro
Some merchants prefer the D3 Pro's desktop form factor, or want the printer as its own box under or beside the counter. That is fine, with one rule: the D3 Pro has no built-in printer and no printer in the bundle, so every retail D3 Pro gets a printer plugged in by USB beside it. Either works and neither brings Ubiquiti:
Label printer by USB when the store prints tags. Receipts, labels and a built-in scanner in one box. This is the usual retail D3 Pro build.
Network printer by USB when the store just wants a plain receipt printer beside the station.
The one thing to avoid: placing that printer somewhere a USB cable cannot reach (a wrap desk across the room, a back office) without quoting Ubiquiti. Away from the terminal, a network printer runs on our network and needs the $10 per month line plus the 5G backup. If a retail merchant wants a printer away from the register, either quote the network or use the label printer on their own Ethernet instead.
The network rule, in retail terms
Agents lose retail deals by putting a $10 per month network line on a quote that did not need one. The rule is simple:
Any printer plugged into the terminal by USB and sitting beside it → no Ubiquiti. Network printer or label printer, T3, P3 MIX or D3 Pro. This is every normal retail counter.
A network printer placed away from the terminal, or a KDS → Ubiquiti required, plus the 5G backup. Retail stores almost never need this.
Label printer on the merchant's own Ethernet → no Ubiquiti. For a label printer in a back room where stock is tagged.
What to tell the merchant about a label printer on their own router. Because it sits on their network, our support team cannot see it or remote into it. If it drops offline, the first check is their router, not us. Setup may recommend the Ubiquiti network for that reason, and the merchant can opt in, but it is not required. By USB at the counter, none of this applies.
Accessories for retail
Label printer. The Sunmi 80mm label printer prints receipts, price tags, barcode labels and linerless labels, and has a built-in barcode scanner. USB to the terminal, or Ethernet to the merchant's router. No Ubiquiti either way. Works with the P3 MIX, T3 and D3 Pro. Templates and label sizes are set in Inventory › Labels; see Printing price tags and barcode labels.
Network printer by USB. The Sunmi 80mm Kitchen Cloud Printer, used as a plain receipt printer beside a D3 Pro or as a second receipt printer beside a T3. No Ubiquiti when it is on a USB cable to the terminal.
Scanners. If the label printer is on the quote, its scanner usually covers the counter. Otherwise, default to the handheld scanner with base; quote the Blink 2 scan box when the merchant wants to pass items over a fixed scanner instead of picking up a gun. Preference, not compatibility. P3 MIX, T3 and D3 Pro only; the P3H takes no scanner.
Cash drawers. Sunmi MAX (full size) or the third-party drawer we resell (confirm the current model with the Stackably team). The Sunmi Mini is no longer offered. P3 MIX, T3 and D3 Pro. The drawer opens automatically on cash sales once enabled; see Hooking Up Cash Drawer to Terminal.
Scale. The Brecknell 6702U-30 bench scale (30 lb, NTEP approved) for stores that sell by weight: candy, bulk food, produce, coffee beans. P3 MIX, T3 and D3 Pro.
Second device. A P3H for the floor, a second counter, or line busting at the holidays. Runs on the store Wi-Fi, no SIM needed. Upsell only.
Edge cases
"The merchant has a big catalogue and wants the biggest screen, but doesn't want to pay for the CPad Pay." T3 with the 10.1" CFD + P2 SmartPad. Same 15.6-inch merchant screen, same dual-pricing display to the customer, lower cost.
"Their counter is high on the merchant side and low on the customer side." CFD + SmartPad. The SmartPad is a separate device that can sit on the low side where the customer can reach it; the CPad Pay is fixed to the back of the station.
"Their stock already has UPC barcodes; they never print tags." Skip the label printer. T3 + CPad Pay (or CFD + SmartPad) + handheld scanner + drawer. If a UPC will not look up in Add by UPC, the product's non-standard code goes in the SKU field and still scans at checkout.
"They want two registers." Two T3s. Each prints its own receipts; neither needs the network. One cash drawer per register.
"They want one register plus someone roaming the floor." T3 at the counter plus a P3H as the upsell. The P3H runs on the store Wi-Fi.
"They have a small back-room workstation where they tag incoming stock." Put the label printer there on the merchant's own Ethernet. Labels are printed from the Inventory Hub, not from the terminal, so the printer does not have to be beside the register. No Ubiquiti, but support cannot remote into it.
"They want the receipt printer under the counter, not on it." D3 Pro with a network printer or label printer by USB. A USB cable reaches under the counter; no network needed.
"Their Wi-Fi is unreliable." The T3 and D3 Pro can be wired by Ethernet. A P3H cannot (no Ethernet port on the device or its cradle); for a P3H the answer is a SIM card ($20 per month) or stepping up to a P3 MIX. Ubiquiti is still not required for retail unless the merchant wants to opt in.
"They sell by weight." Add the Brecknell scale to a P3 MIX, T3 or D3 Pro.
"They want a P3H but also want a cash drawer." Not possible. Step up to a P3 MIX, which takes the drawer, the label printer and a scanner, or go to a T3.
"Two businesses share one storefront with two merchant accounts." One device per MID. Two P3Hs, or a P3H and a P3 MIX, at your discretion. A single terminal cannot run two MIDs today.
"They ordered a D3 Pro and now the quote has a $10 network line." Check where the printer is going. If it sits beside the station on USB, remove the network line. If it really is going somewhere a USB cable cannot reach, the network stays and the 5G backup goes on with it.
"They want the CPad Pay but ordered a D3 Pro, and the CPad in stock is a T3 version." It will not fit. The CPad Pay and the 10.1" CFD each come in a T3 version and a D3 version; confirm the connector on every order.
Quick answers
Does a retail store ever need the Ubiquiti network? Only if a printer is placed somewhere a USB cable cannot reach, or the merchant opts in. A normal retail counter does not.
Which station do I quote? T3 by default. D3 Pro if the merchant wants the printer as a separate box, with a label printer or network printer by USB beside it.
Which scanner? None if the label printer is on the quote. Otherwise the handheld with base; Blink 2 by preference.
Which drawer? Sunmi MAX or the third-party drawer. No Mini.
Do I add a 5G backup? Only if the Ubiquiti network is on the quote.
Do I add a second device? Offer a P3H as an upsell. Do not add it by default.
