This guide defines the hardware Stackably offers, what ships in each terminal bundle, which accessories can be added to each terminal, and the setup we recommend for each kind of business. Use it when building hardware quotes, answering hardware questions, and preparing orders. All hardware is Sunmi unless marked as third-party.
The five rules that decide every quote
A printer plugged into the POS by USB and sitting beside it needs no network. That is true of the network printer and the label printer alike. If it is on the counter with a USB cable to the terminal, there is no Ubiquiti line.
A network printer placed away from the POS means the Ubiquiti network ($10 per month, its own line). Kitchen, bar, prep station, back office, a second counter: anywhere a USB cable to the terminal cannot reach. The printer receives jobs over our network, so the network comes with it. A kitchen display screen (KDS) always requires it.
Default station is the T3. Its receipt printer is built in, so a T3 quote needs no printer at all. Recommend the D3 Pro when the merchant wants a separate printer beside the station (USB, no network) or somewhere away from it (network printer, Ubiquiti).
The D3 Pro never prints on its own. Every D3 Pro quote adds a printer: a network printer or label printer by USB beside it (no Ubiquiti), or a network printer away from it (Ubiquiti).
Quote Ubiquiti only when rule 2 requires it, and add the 5G backup ($20 per month) to every quote that has Ubiquiti.

Choosing between the T3 and the D3 Pro
Both have a 15.6-inch screen, both take the same customer-facing options, both take the same accessories, and both run the same software. The difference is the printer: built into the T3, separate on the D3 Pro.
Start with the T3. The receipt printer is in the base, so a T3 needs nothing else to print receipts and nothing else to be quoted. One footprint on the counter, no printer line, no network line.
Move to the D3 Pro when:
The merchant wants the printer as its own box beside the station. Under the counter, to one side, on a shelf within reach of a USB cable. Add a network printer or a label printer by USB. No Ubiquiti.
The merchant wants the printer away from the station. A wrap desk across the room, a back room, a kitchen. That is a network printer on our network, and it brings Ubiquiti and the 5G backup.
Network printers are already on the quote. A restaurant with a kitchen printer has Ubiquiti anyway, so the D3 Pro's separate receipt printer, wherever it sits, costs nothing extra in network terms.
If you quote a D3 Pro, you must add a printer. By USB beside the station: a network printer (receipts) or a label printer (receipts, labels, built-in scanner). Away from the station: a network printer on Ubiquiti.
The trap to avoid: a network printer placed away from the POS with no Ubiquiti line on the quote. It will not print. The connection, not the printer model, decides the network: USB beside the POS, no network; anywhere else, Ubiquiti.
Customer-facing options on the T3 and D3 Pro
Every T3 and D3 Pro ships with one of two customer-facing setups. Both take the payment, both show the compliant dual-pricing display (cash and card columns per item, cash and card totals), and both run the same software. The choice is preference and budget.
Option | What it is | Choose it when |
11" CPad Pay | One 11-inch tablet that docks into the back of the station. Shows the order and takes the card. | The customer stands at the same counter as the station and the merchant wants the cleanest single-unit look. |
10.1" CFD + P2 SmartPad | A 10.1-inch customer display attached to the station, plus a separate P2 SmartPad that takes the card. | The lower-cost option. Also the right pick when the payment device needs to sit at a different height or position than the station, for example a raised bar top or a counter where the customer side is lower. |
Connector rule, both options. The CPad Pay and the 10.1" CFD each come in a T3 version and a D3 version. Always confirm the connector on the order. A T3 unit will not fit a D3 Pro, and the reverse.
Before you quote
Ubiquiti network: $10 per month per location, quoted as its own line, only when required. Required whenever a network printer is placed away from the POS (anywhere a USB cable to the terminal cannot reach) or a kitchen display screen is on the quote. We provide and program it before it ships. Do not gross up the printer price to cover it; the separate line shows the merchant that their setup requires a network. Do not add it to a quote where every printer is USB-connected beside the POS.
5G backup: $20 per month, on every quote that has Ubiquiti. The backup device is free with the SIM card and runs on the Ubiquiti network. Recommend it as standard wherever the network is on the quote.
Printers on the merchant's own Ethernet: no Ubiquiti, no remote support of the connection. The label printer can also run on the merchant's router by Ethernet instead of USB. Tell the merchant plainly: we cannot see their network, and if the printer drops off it they check their own router first. Setup may recommend Ubiquiti for this reason, but the merchant can decline.
Additional networking: additional cost, quoted per location. A kitchen far from the counter, walls that block Wi-Fi, a large or multi-room space, or cable that needs to be run. Ask where each printer and screen will sit, and contact the team for a networking quote before submitting the proposal. See Networking at Stackably.
SIM cards: $20 per month per card. Only when a P3H or P3 MIX will be used away from Wi-Fi: trade shows, food trucks, mobile businesses. Inside the business, Wi-Fi is enough. We set the SIM up before the device ships.
One MID per device. Each device supports one merchant account. More than one merchant account under one roof (salon suites, shared storefronts) means one device per MID, P3H or P3 MIX at the agent's discretion. A multi-merchant solution is in the works.
Second device for line busting: upsell, not default. Offer it, do not put it on the quote unless the merchant wants it. Retail and service businesses: a P3H. Restaurants: a P3 MIX, T3 or D3 Pro depending on the business.
Terminals
Sunmi P3H
A 6.75-inch terminal with a built-in 58mm receipt printer that takes tap, chip and swipe payments. Used at the counter or carried around the business as a handheld.
Ships with: P3H cradle and wrist strap.
Accessory options: none except a SIM card. If the merchant needs a scanner, cash drawer or external printer, quote a P3 MIX, T3 or D3 Pro instead.
Ethernet: the P3H and its cradle have no Ethernet port. For unreliable Wi-Fi, the options are a SIM card or a P3 MIX.
Product page: Sunmi P3 Family
Sunmi P3 MIX
A 10.1-inch terminal with a built-in 80mm receipt printer and a hand hold on the back.
Ships with: swivel cradle.
Accessory options: 6.7" customer-facing display, handheld scanner + base, Blink 2, MAX cash drawer, third-party cash drawer, label printer, network printer, scale, SIM card.
Note: the P3 MIX uses the 6.7" CFD, not the CPad Pay or the 10.1" CFD. The CFD is an additional charge.
Product page: Sunmi P3 MIX
Sunmi T3
Our default station. A 15.6-inch screen on an elevated stand with a built-in high-speed 80mm printer with auto-cutter, so no separate receipt printer and no network are needed. The T3 does not take payment by itself; the CPad Pay or the P2 SmartPad does.
Ships with: your choice of 11" CPad Pay (T3 connector) or 10.1" CFD (T3 connector) + P2 SmartPad.
Accessory options: handheld scanner + base, Blink 2, MAX cash drawer, third-party cash drawer, label printer, network printer(s), scale.
Product page: Sunmi T3 PRO Family
Sunmi D3 Pro
A 15.6-inch desktop station with an aluminum body and concealed cables. It has no built-in printer and no printer in the bundle. Every D3 Pro quote adds one: a network printer or label printer by USB beside the station (no Ubiquiti), or a network printer away from the station (Ubiquiti required). See Choosing between the T3 and the D3 Pro above.
Ships with: your choice of 11" CPad Pay (D3 connector) or 10.1" CFD (D3 connector) + P2 SmartPad.
Accessory options: handheld scanner + base, Blink 2, MAX cash drawer, third-party cash drawer, label printer, network printer(s), scale.
Product page: Sunmi D3 PRO
Payment and customer-facing devices
Sunmi CPad Pay 11"
The 11-inch payment tablet that docks into the back of a T3 or D3 Pro, faces the customer, takes the card payment and shows the order and dual-pricing display. Standalone use: not currently offered.
CPad Pay, T3 connector: for the T3.
CPad Pay, D3 connector: for the D3 Pro.
Product page: Sunmi CPad PAY
10.1" Customer Facing Display + P2 SmartPad
The lower-cost alternative to the CPad Pay for the T3 and D3 Pro. The 10.1-inch CFD attaches to the station and shows the order and dual-pricing display; the P2 SmartPad is a separate payment device that takes the card and can sit wherever the customer can reach it. Same software and same compliant display as the CPad Pay.
10.1" CFD, T3 connector: for the T3.
10.1" CFD, D3 connector: for the D3 Pro.
P2 SmartPad: one SKU, works with either station.
6.7" Customer Facing Display (CFD) for the P3 MIX
A compact display that connects to the P3 MIX and faces the customer. P3 MIX only, additional charge. It does not take payment; the P3 MIX does.
Printers
One rule for every printer: the connection decides the network, not the model. Plugged into the POS by USB and sitting beside it: no Ubiquiti. Placed anywhere a USB cable to the terminal cannot reach: it runs on our network, and Ubiquiti goes on the quote. The P3 MIX, T3 and D3 Pro take USB printers; the P3H takes none.
Network printer (Sunmi 80mm Kitchen Cloud Printer)
Our 80mm receipt and ticket printer. Fast, with an auto-cutter, rated for grease, water and dust, with a sound and light alert for new tickets. It connects two ways:
By USB to the POS, beside it. Receipt printer for a D3 Pro, or a second receipt printer beside any P3 MIX or T3. No Ubiquiti.
Over our network, anywhere in the building. Kitchen tickets, bar tickets, prep, expo, a second counter. Ubiquiti required ($10 per month per location, plus the 5G backup). As many as the location needs; one network fee covers them all.
Available for the P3 MIX, T3 and D3 Pro.
Product page: Sunmi 80mm Kitchen Cloud Printer
Label printer (Sunmi 80mm Label Printer)
Prints receipts, price labels, barcode labels and linerless labels, and has a built-in barcode scanner, so a retail counter with a label printer usually needs no separate scanner. No Ubiquiti, either way it connects: by USB to the POS beside it, or by Ethernet to the merchant's own router if it needs to sit elsewhere (a back room where stock is tagged, for example). On the merchant's router, support cannot remote into it; setup may recommend Ubiquiti, but it is the merchant's choice.
Where it fits: the standard printer for a retail D3 Pro, a cup-label or receipt printer for a cafe or retail T3, and any merchant who prints price tags. Available for the P3 MIX, T3 and D3 Pro. Restaurant kitchen use is planned for the future.
Product page: Sunmi 80mm Label Printer
Scanners
Scanners are preference, not compatibility. Every terminal except the P3H takes either one. If a label printer is on the quote, its built-in scanner usually covers the counter and no separate scanner is needed. When a separate scanner is needed, default to the handheld scanner with base; quote the Blink 2 when the merchant prefers a hands-free scan box.
Sunmi 2D Handheld Scanner with base (default)
Reads 1D and 2D barcodes and QR codes. Always quote the scanner together with its base. P3 MIX, T3, D3 Pro.
Product page: Sunmi 2D Handheld Scanner
Sunmi Blink 2 (USB)
A countertop scan box that connects by USB. P3 MIX, T3, D3 Pro.
Product page: Sunmi Blink 2
Cash drawers
Two options, both for the P3 MIX, T3 and D3 Pro. The Sunmi Mini cash drawer is no longer offered. Merchants who already have one are supported as before.
Sunmi MAX Cash Drawer
Our full-size Sunmi cash drawer.
Product page: Sunmi MAX Cash Drawer
Third-party cash drawer (model to be confirmed)
A third-party cash drawer that we resell. Confirm the model and its cost with the Stackably team before quoting; this section will be updated when the model is finalised.
Third-party scale
Brecknell 6702U-30
A POS bench scale with an external display, 30 lb capacity in 0.01 lb increments, NTEP approved, with USB and RS-232 connections. Available for the P3 MIX, T3 and D3 Pro. Not part of any standard bundle.
Kitchen display screen (KDS)
Stackably offers a kitchen display screen (KDS). Before quoting, confirm the current KDS device model and its cost with the Stackably team; the device model is not yet finalised in our materials. Every KDS requires the $10 per month Ubiquiti network, quoted as its own line, plus the 5G backup.

Preferred setup by vertical
Start from the row that matches the business, then adjust. The customer-facing option on any T3 or D3 Pro (CPad Pay or CFD + SmartPad) is the merchant's preference. A second device for line busting is always an upsell, never on by default. Each vertical has its own agent guide, linked in the first column.
Business | Preferred setup | Ubiquiti? | Notes |
Good: T3 + CFD/SmartPad + label printer + cash drawer | No | D3 Pro with a USB network printer or label printer beside it, no network. Scale available. Upsell: P3H for the floor. | |
Small boutique / low SKU count | P3H | No | If they need a scanner or drawer, step up to a P3 MIX. |
P3 MIX on swivel cradle | No | Swivel for the tip prompt. Label printer or USB network printer beside the POS for cup labels or tickets, no network. A printer at a bar station away from the POS brings Ubiquiti. | |
P3H + SIM or P3 MIX + SIM, agent's call | No | P3 MIX if they want a cash drawer, CFD, or a USB ticket printer for the cook. No network in a truck. | |
T3 + 1 network printer in the kitchen | Yes + 5G backup | The kitchen printer is away from the POS, so Ubiquiti is required. Add printers or a KDS as the kitchen needs. D3 Pro works well here. Upsell: P3 MIX, T3 or D3 Pro as a second station. | |
P3H or P3 MIX, agent's call | No | P3 MIX shows calendar and services side by side. Retail at the desk needs a P3 MIX for the scanner. Salon suites: one device per MID. See also auto shop, tattoo studio and pet groomer. | |
Small bar: P3 MIX on swivel cradle | No, unless a network printer goes to a service bar or kitchen away from the POS | CFD + SmartPad suits a raised bar top where the payment device sits lower than the station. |
Common questions
Does the D3 Pro come with a printer? No. Add a network printer or label printer by USB beside it (no Ubiquiti), or a network printer away from it (Ubiquiti).
Does the T3 need a separate receipt printer? No. The printer is built in.
When do I pick the D3 Pro over the T3? When the merchant wants the printer as a separate box, beside or away from the station, or when network printers are already on the quote. Otherwise T3.
Does a network printer at the counter need Ubiquiti? Not if it is plugged into the POS by USB. Any printer by USB beside the POS is network-free. A network printer anywhere else runs on our network and brings Ubiquiti.
Does the label printer need Ubiquiti? No. By USB to the POS, or by Ethernet to the merchant's router. On the merchant's router we cannot remote into it; setup may recommend Ubiquiti, but it is optional.
What decides whether Ubiquiti goes on the quote? The connection, not the printer. USB beside the POS: no. Away from the POS on our network, or any KDS: yes.
CPad Pay or CFD + SmartPad? Preference and budget. Both take payment and both show dual pricing. The CFD + SmartPad is cheaper and lets the payment device sit at a different height.
Can a CPad Pay or 10.1" CFD move between a T3 and a D3 Pro? No. Each comes in a T3 version and a D3 version.
Does the P3 MIX use a CPad Pay? No. Its customer display is the 6.7" CFD.
Can accessories be added to a P3H? No. The P3H ships with cradle and wrist strap only and takes only a SIM card. If the merchant needs a scanner, drawer or printer, quote a P3 MIX, T3 or D3 Pro.
Does the P3H take Ethernet? No; neither does its cradle. For unreliable Wi-Fi, quote a SIM card or move to a P3 MIX.
Which scanner do I quote? If a label printer is on the quote, usually none; it has a built-in scanner. Otherwise the handheld scanner with base, or the Blink 2 if the merchant prefers hands-free.
Which cash drawer? The Sunmi MAX or the third-party drawer (model to be confirmed). The Mini is no longer offered.
Do I add the 5G backup? Yes, on every quote that has Ubiquiti.
Do I add a second device? Only as an upsell. P3H for retail and services; P3 MIX, T3 or D3 Pro for restaurants.
How much is the network? $10 per month per location for the basic Ubiquiti network. Additional networking is an additional cost, quoted per location.
