At first glance, Google Voice seems to be the more affordable choice between the two providers because it offers a free version for solopreneurs, whereas Sideline charges $9.99 for one user. But when you look closely and consider the rates for each paid subscription plan, you actually save more money with Sideline.

Google Voice charges $10 per user for up to 10 users in its entry-level plan, whereas Sideline charges a flat rate of $9.99 for up to five team members. This means you’ll be paying $50 on Google Voice for five agents, and maintain the $9.99 fee on Sideline for the same number of people on the account. When you upgrade to the highest-tier plans, Sideline charges $9.99 per line, whereas Google Voice requires $30 per user, a significantly large price difference.

Given this, Sideline wins in the Sideline vs Google Voice pricing debate. It offers a free trial for both Standard and Team Number plans, allowing users to access ​​unlimited calls and texts, group messaging, and auto-replies, at no cost for seven days.

Best for Virtual Phone Numbers: Sideline

Local and vanity numbers Number porting is free Shared number for up to five team members	Local numbers Number porting requires a one-time fee of $20

In the battle between Google Voice vs Sideline for the best phone numbers, Sideline offers better advantages, going beyond local numbers and letting businesses secure a vanity number. Additionally, the Team Number plan includes a shared number that a maximum of five team members use. On the other hand, Google Voice only allows local numbers.

With Sideline, number porting is free of charge and easy to facilitate. On the app settings, under Number Porting, you simply have to enter your 10-digit number, wait for the verification text message, and reply to confirm that the number is yours and active. Google Voice also supports number porting but charges a one-time fee of $20.

Best for Text Messaging: Sideline

Unlimited text messaging in the U.S. Group messages for up to 10 recipients Multimedia messaging service (MMS) Custom signature Auto-reply for missed calls International SMS to 35 countries	Unlimited text messaging in the U.S. Group messages for up to 7 recipients MMS

In comparing the text messaging solutions between Google Voice vs Sideline, Sideline again makes for a more favorable option because it has more robust tools than Google Voice. Both providers offer unlimited text messaging in the U.S. and support MMS, allowing users to send JPG, PNG, and GIF files. However, unlike Google Voice, Sideline features an auto-reply, sending texts to customers automatically when you don’t answer a call or a message.

Moreover, you get to customize replies on Sideline. Let clients know that you’re in a meeting, or on vacation, or the reason you’re not able to respond quickly. You have the option to include a custom signature, giving a more professional touch to messages. Finally, what makes Sideline a better text messaging service than Google Voice is it allows you to send texts to 35 countries. In contrast, Google Voice doesn’t support international SMS.

Best for Call Handling: Google Voice

Caller ID Custom greetings Call screening Call blocking Custom call forwarding Call transfer Business hours routing One-click dialing Call recording Ring groups Multi-level auto-attendant	Caller ID Custom greetings Call blocking Call forwarding Auto-attendant

In this Sideline and Google Voice comparison, we found that the platforms share similar call handling features, including caller ID, call blocking, and call forwarding. However, Google Voice has valuable tools Sideline doesn’t have. For instance, it has business hours routing, letting you assign calls to specific phone numbers within a particular schedule. Its ring groups alert several team members about an incoming call, ensuring you don’t miss any inquiries.

Google Voice’s multi-level auto-attendant makes it easy to distribute calls to the proper agents and departments without human intervention. Its call recording facilitates effective employee performance evaluation. Given these capabilities, Google Voice trumps Sideline in the call handling round.

Best for Team Collaboration: Google Voice

Integrates with Google Chat, Meet, and Calendar Group texting	Shared number Group texting

When evaluating Google Voice versus Sideline’s team collaboration tools, Google Voice is the clear winner because it has features that go beyond typical phone system capabilities. Through its integration with other Google Workspace products, you get to use a unified communications platform. Message colleagues on Google Chat and plot upcoming events through Google Calendar. Discuss important matters at length via Google Meet.

Unlike Google Voice, Sideline doesn’t offer or integrate with unified communications tools. However, it facilitates collaboration through shared numbers and group texting.

Best for Flexibility & Mobility: Google Voice

Android and iOS apps Windows, MacOS, and Chrome OS Web browsers Wi-Fi or cellular Desk phone support	Android and iOS apps Windows and MacOS Sideline Web Wi-Fi or cellular

Both Google Voice and Sideline offer mobile apps for Android and iOS devices. This allows users to take the phone system with them wherever they go. You can place and take calls on these apps by connecting to a Wi-Fi network or your cellular data. While facilitating mobility, the platforms also work on web browsers and different operating systems.

However, Google Voice has a slight advantage in terms of device flexibility because it offers desk phone support, which Sideline doesn’t. This is among the biggest Sideline and Google Voice differences, an essential consideration for small businesses that still prefer hardware devices. Users are able to connect select Poly devices to Google Voice and cater to team members who are more comfortable using desk phones when managing calls.

Best for Customer Support: Sideline

Text messaging Email Sideline bot Live agent chat Help center	Ticket submission via the Admin console Community forum Help center

Compared to Google Voice, Sideline offers more customer support channels, giving businesses plenty of avenues for requesting assistance. Connect with the provider through live chat, SMS, or email, or use the chatbot to get fast responses. Sideline Chatbot provides auto-suggested topic options and makes it easy for businesses to relay concerns.

If, during the conversation with the chatbot, you feel the need to speak to an agent, it will connect you to a human customer service representative. Aside from direct channels, Sideline has a help center facilitating self-service.

Meanwhile, Google Voice’s customer service platforms are mostly for self-service, the help center, and community forums. The ticket submission tool in the Admin console is the only channel for direct communication with the provider.
