Heilo vs Google Voice for Business: Which One to Choose?

In short: Google Voice is telephony for Google Workspace (numbers, ring groups, auto attendants), sold per user as an add-on, and its AI notes work in English only. Heilo is not a phone system: it records calls, transcribes and summarises them in Polish, and sends the results to your CRM. With Heilo Line, each rep gets a Polish +48 number.

Before you choose, decide what a finished call must deliver: just the recording, a note for the rep, or an activity on the right customer in the CRM. Each of these results needs a different level of setup.

Status: 20 October 2026. Per Google's supported-countries list (checked 20 October 2026), Google numbers are offered in 14 countries, including the US, Canada, the UK, Germany, France, Spain and the Netherlands, and Carrier Link and SIP Link in 34; Poland is not on the list. Per the App Store listing (checked 20 October 2026), Google Voice works for personal Google Accounts in the US only, and for Workspace accounts in select countries. Heilo Line is a Polish +48 number that dials +48 numbers only, so Heilo suits teams that call customers in Poland.

How we compared: this comparison is published by the Heilo team, the vendor of one of the compared systems. We checked Google's scope in its documentation and Heilo's scope in the current offer and product documentation. It is an analysis of features and rollout conditions, not a joint quality test of both services. We did not measure transcription accuracy or time saved. The examples below are scenarios for your own test.

Heilo vs Google Voice: key differences

Google sources: Voice offer, Workspace add-on features, terms of the notes feature (checked 20 October 2026). Heilo: plans and prices, sending calls to your CRM.

When to Choose Google Voice and When Heilo

Consider Google Voice if your company is on Workspace in a listed country and mainly needs a shared phone system with ring groups, queues and auto attendants, if you talk to customers in English, or if you call customers outside Poland. Check the available notes instead of assuming that Google offers voicemail only.

Check Heilo if your reps talk to customers in Poland, in Polish, and the price, deadline and next step should reach the CRM. Heilo does not require a B2B team to change its CRM. Its job is to keep the conversation and prepare data that an integration writes to the sales system you already use. With Heilo Line, each rep has their own +48 number, answers and dials through it, and calls are recorded automatically.

If you only need messages after a missed call, start with Heilo Voicemail. Do not buy Heilo Line before you check whether the team really needs all calls recorded.

If queues, routing between departments and heavy call handling are the key requirements, compare phone systems; see Heilo vs Vonage. Heilo does not replace everything in that category.

Polish Calls: Language Support and Quality Are Separate Questions

Google introduced "take notes for me" in Voice in June 2026. The feature produces a record of the call, a summary and next steps. Google announcement of 16 June 2026 (checked 20 October 2026).

The admin documentation lists the Voice Standard and Premier add-ons and the eligible Workspace editions: Business Standard/Plus and Enterprise Standard/Plus. Notes are currently available in English only, with one language per call. Buying Voice Standard with just any Workspace edition is not enough to confirm access. Notes work only when call recording is enabled, and automatic recording is available only in Voice Premier. Google requirements (checked 20 October 2026).

Heilo processes calls in Polish: after a call through a Heilo Line number you get a transcript, a summary and task suggestions, and on a two-sided call also feedback from the call coach on what went well and what to improve. Still, test your own names, amounts, product names and deadlines. Language support does not guarantee an error-free record.

Example to test (said in Polish): „Proszę o ofertę na 40 urządzeń z montażem. Dostawa do końca miesiąca, ale ofertę potrzebuję przed piątkiem” ("Please send a quote for 40 units with installation. Delivery by the end of the month, but I need the quote before Friday"). Check whether the result keeps the quantity, the scope and both different deadlines. Every system should let you verify an important agreement in the recording.

Which Calls Heilo Actually Records

With Heilo Line, simply dialling a number on your phone's keypad does not start recording in Heilo. You start an outbound call in the dashboard with the "Call via Heilo" button, to +48 numbers only: Heilo connects the rep's phone first and then the customer, who sees the Heilo number. To plan the next call with that customer, use "Schedule call": it goes to "Planned" with a day and an optional time. More: recording outbound calls.

Heilo Select requires conference calling from your phone and carrier. The user adds Heilo to the call and tells the other person about the recording themselves; Heilo records from the moment it joins. In this plan Heilo does not receive the customer's number automatically; you have to add it so that an integration can match the call to the right contact.

Heilo Line requires company verification by its Polish tax number (NIP). After verification you choose a number and Heilo orders it from the carrier, so the activation time depends on the verification. Before you buy, confirm that enough numbers are available for your team. New numbers start in the "Announcement before the call" mode: the other person hears a notice about the recording, and you can change the mode in the number's settings. Heilo gives you the tools to inform the caller (a notice, your own wording, a call label). Your company, as the data controller, provides the legal basis and meets the duty to inform. Heilo listens and prepares the record; it never talks to the customer on your rep's behalf.

CRM Integration: Check the Whole Flow

Heilo offers an API and signed webhooks. You can connect them to your CRM directly or through Zapier/Make. Some setup is needed: choosing events, mapping fields, finding contacts and handling repeated delivery of data. This is not a promise of a ready-made native integration with every CRM. Setup guide.

Before you buy, run the same scenario in both systems: a call with an existing contact ends with an offer to send tomorrow. The result should land on the right contact, include the deadline and create a task if you require one. Repeating the event should not create a second activity.

According to Google, only the person who started the notes has access to the recording, transcript and summary; others see only the summary from the email forwarded to them. Do not equate this with an automatic CRM entry or shared team access. Ask to see the exact export method and permissions. Google notes access (checked 20 October 2026).

Google marks the beta of the Voice integration with Salesforce as closed, with access revoked. Older instructions do not confirm that you can start it now. Current status of the Google integration (checked 20 October 2026).

Costs: Compare the Same Scope

Google publishes the prices of the Voice add-ons: Starter USD 10, Standard USD 20 and Premier USD 30 per user per month, charged in US dollars, plus Workspace (billing page, checked 20 October 2026). For a team, the Workspace subscription is a separate item.

An example calculation for five people:

These are different billing models. Do not compare five licences with one number without checking concurrent calls and how calls are assigned to employees. The table does not confirm that you can set up that many numbers on a self-service basis. With Google, also count the cost of upgrading your Workspace edition for the notes feature.

Heilo plans do not require a separate base subscription. Prices are net, VAT is added at payment, and billing is monthly (see the pricing page). Heilo Line includes 6 hours of recorded calls per number in each billing period; each extra hour is billed per minute at the rate on the pricing page and added to the next invoice. Heilo Voicemail and Heilo Select carry an indicative limit of 500 recorded minutes per number per month that never blocks calls. Discuss a larger volume before you buy. Check separately the forwarding and conference charges at your own carrier, and any integration fees. With Google, verify the rates for the destinations you need.

Test Before You Buy: Five Calls, Not a Demo

Run test calls with people who know about the test, and note the result of each step:

1. Missed call: does the customer leave a message, and does it reach the right person?
2. Inbound call: does the recording cover both sides, and does the recording notice work as set on the number?
3. Outbound call: does the rep call from the dashboard (in Heilo, with the "Call via Heilo" button), and does the customer see the right number?
4. Polish agreements: are amounts, surnames, negations and two different deadlines recorded correctly?
5. CRM and access: does the result reach the right contact without a duplicate, and can authorised people see it?

Measure the time from hanging up to a finished activity in the CRM, and the time spent on manual corrections. Record how many of the five scenarios ended correctly. This is the result of your pilot, and it will help you judge the cost of a useful call. It does not replace a measurement at larger volume.

Also check how long each system keeps recordings. In Heilo, a recording is kept for 365 days by default and then deleted; the transcript stays. A call moved to the trash is erased 30 days later together with its recording, transcript and summary; an entry with the number, the date and the notes remains. Agree on roles and permissions, a data processing agreement and the deletion of copies sent to your CRM. Heilo uses subprocessors, including Twilio (telephony, a US company), Supabase (database on EU infrastructure), Vercel (hosting) and Google Gemini (transcription and analysis); the full list is in the terms.

Practical Questions Before Rollout

Can I keep my current number, and what will the customer see when I call back?

Forwarding, number porting and a new number are different solutions. With Heilo, Heilo Voicemail and Heilo Select work with your existing number, and Heilo Line is a new Polish +48 company number. On a call started with "Call via Heilo" the customer sees the Heilo number; ordinary dialling from the rep's phone does not use that path. See adding Heilo to a call.

Will Heilo replace ring groups and queues in a phone system?

Heilo focuses on recording calls and passing agreements to the CRM. It has no queues, IVR menus or extensions, and it does not ring a group of employees at once; one number rings one phone. If these are requirements, look at a separate phone system. Heilo vs Vonage.

Can the team share recordings?

In Heilo you invite team members to the account and give them roles: owner, admin, manager or member. In Google Voice, the recording, transcript and summary from notes are visible only to the person who started them; an administrator's permissions over company recordings are a separate matter. Test permissions, export and deletion before you buy.

How do I handle greetings and calls outside business hours?

Decide separately on the wording of the message, the schedule and the call route when an employee does not answer. In Heilo you set greetings and their schedule per number. Greeting examples and a guide to handling calls outside business hours will help.

FAQ: Heilo or Google Voice?

Is Google Voice available in my country?

Check Google's supported-countries list (checked 20 October 2026). It names 14 countries for Google numbers and 34 for Carrier Link and SIP Link; Poland is not on it. Per the App Store listing (checked 20 October 2026), Google Voice works for personal Google Accounts in the US only. Check the current list before you buy, and do not assume availability just because your company uses Workspace.

Does Google Voice summarise calls?

Yes. "Take notes for me" processes calls in eligible plans. It currently supports English only, and the conditions also cover your Workspace edition and administrator settings.

Does Heilo replace a sales team's CRM?

Heilo passes the result to the CRM your company already uses. Small firms without a separate CRM can use the built-in Contacts, Projects and Tasks.

Can I use Google Voice and Heilo together?

We do not confirm such a setup in this comparison. First check whether forwarding is possible and what it costs, how the caller's number is passed on, and how the call is recorded in your specific plan. We do not promise a tested integration of the two services.

What should a team that sells in Poland choose?

If organising telephony in Workspace matters most, evaluate Google Voice once you have confirmed the conditions for your country. If you need Polish summaries and data in your CRM, test Heilo on the five scenarios above. Base the decision on the result of your pilot and the full cost of rollout.
