Allo, best for small teams

What is Allo?

The company also offers a mobile-first approach where users can seamlessly switch between desktop and mobile devices.

Who is Allo best for?

Allo is ideal for small companies looking for an intelligent, user-friendly phone solution to manage customer interactions without the need for complex setup, a learning curve, or ongoing support.

Allo also offers two apps that you can download from the Apple App Store or Google Play Store. Once installed, simply set up your business by selecting a phone number, customizing greetings, setting preferences, and activating your AI Receptionist. After that, you're ready to start receiving calls.

Pros & Cons of Allo

Allo Pricing

Like Quo, Allo offers a Starter plan at $18/month (billed yearly). However, Allo stands out by providing coverage in both Europe and North America, whereas Quo is limited to the US and Canada.

The Business plan offers even more value, including three users for $32/month (billed yearly). In comparison, Quo charges $33 per user per month, meaning Allo provides a more cost-effective solution for small teams, with all three users covered for nearly the same price as a single user on Quo.

For example, with the calendar integration, you can sync your calendar with Google Voice to automatically decline calls when you're in a meeting or set your availability based on your calendar working hours, while with Meet it is possible to identify incoming Google Voice calls.

Frequently Asked Questions About Quo Alternatives

[[faq-blog]]

What's better than Quo?

The answer depends on your company's size and needs. Allo is best for small businesses and solo entrepreneurs seeking an affordable, AI-powered communication solution with fixed pricing that includes all features. For larger organizations, RingCentral is better if you need an all-in-one communication platform with voice, video, messaging, and integrations for a unified experience. Aircall can also be a suitable option if you prioritize CRM integrations and are ready to spend a bit more.

What are Quo's main limitations?

Quo was designed for small businesses. While it works well for small companies and solopreneurs, larger teams may encounter limitations. Specifically, the platform offers superficial CRM integrations (their HubSpot app scores 3.3/5 on the HubSpot marketplace), prohibits cold calling, and lacks a robust spam filter.
