If you’re an Independent Software Vendor (ISV) or developer building a POS, inventory, loyalty, or payments app, the SUNMI App Store is your direct line to thousands of active merchants through the SUNMI Store, especially in North America. This guide walks you through the entire process: from understanding what the SUNMI ecosystem offers, to submitting your APK to the SUNMI Store, getting certified, and reaching your first customers.
What Is the SUNMI App Store?
The SUNMI App Store is a curated marketplace embedded within SUNMI’s device ecosystem. It allows partners, like ISVs and resellers, to publish apps they develop or operate, then distribute those apps at scale to merchants running SUNMI hardware.
SUNMI’s devices include:
- Desktop POS, SUNMI D2s, SUNMI D2 Lite, SUNMI T2s, SUNMI T2s Lite
- Handheld POS / Mobile POS, SUNMI P2, P2 Pro, P15
- Android Kiosks, SUNMI K2, SUNMI K1
- SUNMI CPad, Tablet-based POS terminals
- PDA, Handheld scanners for inventory and logistics
These devices run SUNMI OS, a remotely managed hardened Android environment. The App Store gives merchants an organized way to discover and install business apps directly onto their terminals, without sideloading or manual APK management.
Who Uses SUNMI Devices?
SUNMI serves merchants across restaurants, retail, grocery, healthcare, and logistics in more than 100 countries. In North America, SUNMI has significantly expanded its presence through authorized distributors like Rosper Technology, with a growing fleet of devices deployed across SMBs and enterprise accounts alike.
Why Publish on the SUNMI Store?
Publishing on the SUNMI App Store puts your app in front of a built-in merchant audience that is already using SUNMI hardware for daily operations. That means:
- Zero hardware compatibility research, you know exactly which OS and screen sizes your app needs to support
- Managed distribution, SUNMI’s MDM (Mobile Device Management) platform handles device assignment and app rollout
- Merchant trust, apps listed in the official store carry credibility that sideloaded APKs don’t
- Scalable deployment, push updates to one device or thousands through the partner portal
For ISVs building vertical SaaS (restaurant POS, inventory management, loyalty programs, appointment scheduling), the SUNMI Store is a high-conversion distribution channel with relatively low barriers to entry.
Prerequisites: What You Need Before You Start
Before you can publish, make sure you have the following in place:
1. MDM (Partner Platform) Account
All app publishing happens through SUNMI’s MDM Partner Platform at partner.sunmi.com. If you don’t already have an account, you’ll need to apply for one there. Approval is required, SUNMI reviews partner accounts before granting publishing access.
2. SUNMI App ID
Each app published on the SUNMI Store is assigned a unique SUNMI App ID. This is generated when you register your app in the developer portal, and it must be included in your APK’s metadata.
3. A Signed APK
Your app must be packaged as a standard Android APK, signed with your developer certificate. SUNMI supports standard Android app publishing, no special SUNMI-specific SDK is required for submission, though integrating SUNMI’s hardware SDKs can unlock device features (printers, scanners, card readers) that improve your app’s merchant appeal.
4. App Store Listing Assets
Prepare the following before you start the submission workflow:
- App name and description (merchant-facing, clearly explain the value proposition)
- Category selection (POS, Inventory, Payments, Loyalty, etc.)
- App icon (standard Android icon sizes)
- Screenshots showing the app running on a SUNMI device (recommended)
- Privacy policy URL and terms of service URL
- Supported device models list
Step-by-Step: Submit Your App to the SUNMI Store
Based on SUNMI’s official publishing workflow, here are the steps:
Step 1, Log in to the MDM Partner Platform
Go to partner.sunmi.com and log in with your partner account credentials.
Tip: If you don’t have an MDM account yet, visit the registration page at partner.sunmi.com and submit an application. Approval times vary; apply early to avoid delays.
Step 2, Navigate to App Publishing
In the MDM dashboard, go to:
Development → App Publishing
If you don’t see this option in your account menu, send an email to [email protected] and request that the App Publishing function be enabled for your account. This is a common issue for newly registered partners.
Step 3, Register Your App
If this is your first time publishing, you’ll need to register the app:
- Enter the App Name
- Provide the SUNMI App ID (obtained during developer registration)
- Select the relevant category (e.g., POS System, Inventory Management, Loyalty)
- Fill in the description and upload your listing assets (icon, screenshots, etc.)
Step 4, Upload Your APK
Click the ”Click or drag your APK here to upload” button in the portal and select your signed APK file from your computer.
APK Requirements:
– Must be a valid, signed Android APK (.apk format)
– SUNMI recommends using Android SDK level consistent with their OS versions (generally Android 9–13 based on device model)
– The APK should not request permissions that are incompatible with SUNMI’s security model
– If your app uses Google Mobile Services (GMS), verify that your target device model supports GMS (some SUNMI models ship without GMS)
Step 5, Select Compatible Device Models
One of the key settings in the portal is model targeting. You can choose which specific SUNMI device models will see and be able to install your app in the store.
Be precise here, publishing for models you haven’untested can result in negative reviews and support tickets. Common models for North American merchants include:
- SUNMI P2 / P2 ProSUNMI D2s://rrospertech.com/product/sunmi-t2s/”>SUNMI T2s, SUNMI D2s (desktop POS), SUNMI T2s Lite (countertop POS)
- SUNMI D2s Lite / D2s (SUNMI K2 (kiosk)
- SUNMI T2s / T2s Lite (countertop POS)
- SUNMI K2 (kiosk)
Step 6, Submit for Review
Once your APK and listing are ready, submit the app for review. Here’s how the approval process works:
| Approval Type | Timeline | Notes |
|---|---|---|
| Standard Review | Up to 2 business days | Submitted through the portal |
| Expedited Review | Contact SUNMI directly | Email [email protected] for urgent releases |
SUNMI reviews apps for technical compatibility, content policy compliance, and functional stability. Make sure your app:
- Launches without crashes on the targeted device models
- Doesn’t require permissions that conflict with SUNMI’s security model (e.g., disabling SafetyNet)
- Has a clear, legitimate merchant use case
Step 7, App Goes Live
After approval, your app appears in the SUNMI App Store for the device models you selected. Merchants can discover it, read your listing, and install it directly from their device or through the MDM portal.
You can monitor installs and push updates through the same Development → App Publishing section.
SUNMI Store Certification: What Reviewers Check
While SUNMI doesn’t publish a exhaustive public checklist, the certification process generally covers:
1. APK Stability, App installs and launches without force-closes on target devices
2. Permission Appropriateness, No requests for disallowed or incompatible Android permissions
3. Content Policy, App content must be appropriate for a merchant/business environment
4. Device Compatibility, App is fully functional on all device models selected during submission
5. Privacy & Data, A privacy policy URL is provided; app handles user data responsibly
If your app is rejected, you’ll typically receive feedback through the MDM portal. Address the issues and resubmit.
How Rosper Helps ISVs Publish on the SUNMI Store
As SUNMI’s authorized North American distributor, Rosper Technology plays a hands-on role in helping ISVs and resellers get their apps deployed on SUNMI hardware. Here’s how Rosper supports the process:
Device Testing & Pilots
Before you submit to the App Store, you need real hardware for QA. Rosper maintains a fleet of SUNMI devices available for pilot programs. ISVs can request devices to run compatibility testing, validate APK behavior on specific models, and confirm that hardware features (printer, scanner, card reader) work as expected.
MDM Configuration Assistance
Rosper’s technical team helps configure your MDM account, enable App Publishing features, and set up device groups for targeted rollout. If you’re new to the SUNMI ecosystem, this guidance can save days of trial and error.
Hardware Procurement + Pre-Loading
When you’re ready to go to market, Rosper can supply devices pre-configured with your app already installed, ideal for reseller partners who want to deliver a plug-and-play experience to their merchant customers.
U.S. Stock & Fast Shipping
Rosper holds inventory in the United States, enabling fast delivery for devices needed for development, demos, and pilot deployments. No long overseas lead times.
SUNMI in North America: The Market Opportunity
SUNMI has accelerated its North American push in recent years, with a portfolio that now spans the full spectrum of merchant form factors, from handheld POS units for field service to full-size countertop terminals for quick-service restaurants.
Key vertical focus areas in the U.S.:
- Quick-Service Restaurants (QSR), SUNMI’s dual-screen T2s and compact D2s devices are popular for order-taking and payment at the counter
- Retail, Handheld P2 devices support line-busting, inventory checks, and mobile checkout
- Grocery & Specialty Retail, PDA devices with built-in scanners for fresh category management
- Logistics & Warehouse, Ruggedized handheld terminals for inventory and fulfillment operations
For ISVs, this growing installed base represents a captive hardware audience actively looking for software solutions. Unlike the general Android app market where hardware fragmentation is a major challenge, SUNMI’s controlled device ecosystem means your app needs to validate against a defined list of models, a much more manageable QA scope.
