For most shift-based staff communication, app notifications are the better default — they’re free to send, deliver rich content with direct links to the roster or shift, and confirm who has read them. Reserve SMS for genuinely urgent messages — a no-show that needs covering in the next hour, a last-minute change, or reaching someone who rarely opens the app — where near-guaranteed delivery matters more than cost. The strongest setup uses both: apps for routine roster updates and reminders, SMS as a targeted fallback for time-critical alerts. A staff communication app that supports both channels lets you balance cost, reliability, and speed automatically.
Whether you’re running a café, retail store, healthcare facility, or any business with shift workers, the communication method you choose affects everything from how quickly you can fill last-minute shifts to how well staff stay informed about schedule changes. Many businesses default to SMS because it’s familiar, while others rely on WhatsApp group chats that often fail for shift teams. App-based notifications offer advantages that can transform how you manage your team while significantly reducing costs.
This guide compares SMS and app notifications across the factors that decide the choice — cost, reliability, functionality, and staff adoption — and explains how modern workforce management platforms combine both methods so the right message reaches your team through the right channel.
Quick summary

App notifications are free while SMS costs 5-15 cents per message, adding up quickly for regular communication
- Functionality:
Apps provide richer notifications with links to rosters, shift details, and action buttons SMS can’t match
- Best strategy:
Hybrid approaches using apps for routine updates and SMS for urgent alerts work best for most businesses
- Automation:
Integrated platforms automatically send notifications when rosters change, eliminating manual message sending
SMS vs app notifications at a glance
Before the detail, here’s how the two methods stack up across the factors shift-based businesses weigh most:
SMS vs app notifications for staff compared
| Factor | SMS | App notifications |
|---|---|---|
| Cost per message | 5-15 cents each in Australia | Free once installed |
| Content | Plain text, 160 characters | Rich text, links, images, buttons |
| Delivery | Carrier network, no internet needed | Requires internet connectivity |
| Read visibility | No read confirmation | Read receipts and delivery status |
| Action from the message | None — must log in separately | Accept shift, view roster, respond |
| Device needed | Any mobile phone | Smartphone (or web access) |
| Best for | Urgent, time-critical alerts | Routine rosters, reminders, announcements |
Both channels are available in RosterElf — the split above reflects each method’s typical strengths, not a limitation of the platform.
Cost comparison: SMS vs app notifications
The cost difference between SMS and app notifications becomes significant quickly. SMS in Australia typically costs 5-15 cents per message depending on your provider and volume. For a team of 20 employees receiving just 2 roster update messages per week, you’re looking at $200-600 annually. Add shift reminders, last-minute changes, and other communications, and costs can easily exceed $1,000-2,000 per year for a small team.
App notifications, by contrast, are free once staff have installed the app. Whether you send 10 notifications or 1,000, there’s no per-message cost. This makes apps dramatically more cost-effective for regular communication. The savings compound as your team grows — a business with 50 employees could save $5,000+ annually by moving routine communications from SMS to app notifications.
However, the comparison isn’t purely about per-message costs. SMS requires no app installation or training, while apps need initial setup time. For businesses already using employee rostering software, the app is typically already part of the platform, making the transition straightforward. The cost savings from app notifications usually justify any initial setup effort within the first few months.
Functionality: what each method can do
SMS and app notifications have fundamentally different capabilities that affect how useful they are for workforce communication:
SMS capabilities
- Plain text messages up to 160 characters
- Works on any mobile phone
- Relies on cellular network coverage
- No confirmation of message read
- Limited formatting options
- Cannot include actionable buttons
App notification capabilities
- Rich notifications with images and formatting
- Direct links to relevant roster or shift
- Action buttons (accept shift, view details)
- Read receipts and delivery confirmation
- In-app message history
- Interactive features and responses
The functionality gap is significant. App notifications can link directly to a specific shift in your time and attendance system, show the full roster at a glance, or include buttons for staff to accept coverage requests immediately. SMS messages are limited to basic text and require staff to log into a separate system to take action.
Reliability and deliverability
Reliability is where SMS earns its keep. Because it travels over carrier networks rather than the internet, an SMS reaches a phone even with no data connection or a weak signal, and it’s widely reported that the vast majority of text messages are opened within minutes of arriving. That near-universal reach is exactly why SMS remains the right tool for a genuinely urgent alert.
App notifications depend on internet connectivity and on the employee having notifications enabled — but they answer a question SMS can’t: did the person actually see it? Read receipts and delivery status let a manager confirm a roster change was viewed and follow up with anyone who hasn’t confirmed. For accountability across a shift team, that visibility is often more valuable than raw deliverability, which is why the most reliable setup pairs app notifications for the record with SMS as the urgent fallback.
Common staff communication mistakes to avoid
Many businesses make predictable mistakes when implementing staff communication systems:
Using SMS for everything
Sending all communications via SMS wastes money on routine messages that don’t require immediate attention or SMS delivery.
No backup communication method
Relying solely on app notifications without SMS backup means critical urgent messages may be missed if someone hasn’t opened the app.
Poor app adoption strategy
Not properly onboarding staff to the app means they continue checking multiple places for roster information, defeating the purpose.
Message overload
Sending too many non-critical notifications trains staff to ignore messages, reducing effectiveness when urgent communication is needed.
Unclear message protocols
Not establishing clear guidelines about what requires immediate response versus what’s just informational creates confusion and anxiety.
Manual message sending
Manually composing and sending every notification wastes manager time and increases the chance messages are delayed or forgotten.
When to use SMS vs app notifications
The most effective communication strategy uses both methods strategically rather than choosing one exclusively. Here’s how to decide:
Use app notifications for
Roster published notifications, shift reminders 24 hours ahead, approved leave confirmations, shift swap approvals, general announcements, policy updates, and any communication where staff can respond within a few hours.
Use SMS for
Emergency coverage needs (someone didn’t show up), last-minute roster changes within 2-3 hours of shift, critical urgent alerts, important messages to staff who rarely check the app, and backup notifications when immediate response is essential.
Use both simultaneously for
Critical alerts that require immediate attention and confirmation, such as workplace safety incidents, emergency closures, or mandatory urgent meetings. The app provides details while SMS ensures delivery.
How to drive staff app adoption
Getting team members to install and regularly use a staff communication app requires a clear strategy:
-
Onboard during employment start: Include app installation in your onboarding process. Have new employees install and test the app on their first day before they go home.
-
Emphasise employee benefits: Frame the app as beneficial for staff, not just management. Highlight instant roster access, easy shift swaps, quick leave requests, and always having their schedule in their pocket.
-
Make it the only source of truth: Stop publishing rosters on noticeboards or via other methods. When the app is the only place to see your schedule, adoption follows naturally.
-
Integrate all workforce functions: Use a platform where rostering, time tracking, leave requests, and communication all happen in one app. Staff will use it daily for clocking in, making other features familiar.
-
Provide clear setup instructions: Create simple step-by-step guides with screenshots. Offer to help older or less tech-savvy staff through the installation process.
-
Set expectations: Clearly communicate that checking the app daily is part of the job. Include this in position descriptions and discuss it during performance reviews.

Frequently asked questions
Should I use SMS or app notifications for roster changes?
App notifications are better for most roster communication as they’re free, instant, and provide richer information. However, SMS is useful as a backup for critical urgent messages or for employees who don’t check the app regularly. A staff communication app that supports both gives you flexibility.
How much do SMS notifications cost for staff scheduling?
SMS costs typically range from 5-15 cents per message in Australia. For a team of 20 staff receiving 2-3 messages per week, this can cost $200-500+ annually. App notifications are free, making them significantly more cost-effective for regular communication.
Are app notifications or SMS better for reaching staff?
It depends on urgency. App notifications win for routine roster updates because they carry links, action buttons, and read receipts at no per-message cost. SMS wins for time-critical alerts — it works without internet and is opened within minutes, so it’s the right call for a no-show that needs covering fast. The best approach uses both channels and picks by message type.
Do all employees need smartphones for app notifications?
Most modern staff communication apps work on both smartphones and basic devices through web access. However, push notifications require a smartphone. For employees without smartphones, hybrid approaches using SMS for critical alerts and email for detailed information work well.
Can app notifications be turned off by employees?
Yes, employees can disable app notifications on their devices. However, quality workforce communication apps send notifications through multiple channels (push, in-app, email) and allow managers to see delivery status. Setting clear expectations about checking the app regularly helps ensure messages are seen.
Are SMS messages more reliable than app notifications?
SMS has high deliverability but depends on phone signal and carrier reliability. App notifications require internet connectivity but offer read receipts and confirmation features. Modern communication systems provide better accountability through delivery tracking and in-app message history.
What types of messages should be sent via SMS vs app?
Use app notifications for routine roster updates, shift reminders, and general announcements. Reserve SMS for urgent last-minute changes, emergency coverage needs, or critical alerts when immediate response is required. This approach balances cost-effectiveness with appropriate urgency, and helps reduce no-shows without over-messaging your team.
How do I get staff to install and use the app?
Introduce the app during onboarding with clear setup instructions. Emphasise employee benefits like instant roster access, easy shift swaps, and leave requests. Make app usage part of standard procedures and ensure rostering and time tracking features are only available through the app to drive adoption. For a complete strategy, see our guide on getting staff to actually use your rostering app.
Can I integrate communication with rostering systems?
Yes, integrated platforms combine employee rostering, time tracking, and communication in one system. When rosters are published or changed, notifications go out automatically. This eliminates manual message sending and ensures staff always have current information through the communication tools.
