How do businesses use Chalkboard?

Phone illustration

Replacement for work phones. Use Chalkboard instead of assigning your team physical work phones. Avoid the pitfalls of letting your team use their own phones for work.

Replacement for work phones

Instead of a phone system. Phone systems tie your team to desks and can be complicated to configure. Chalkboard is the simpler alternative to clunky old phone systems.

The under appreciated 2nd SIM Alternative!

Using Chalkboard is intuitive and it's speedy when it comes to talking / sending-receiving texts. I personally use this as an alternative to getting a second sim because my sim tray is broken. Now I have access to multi-sim functionality without the extra cost of buying a new phone!

Thank you Chalkboard!

Well worth the investment

I've been using Chalkboard for quite some time now. I am grateful for such an amazing application for a low monthly cost that lets me utilise a separate business phone number for customer's phone calls and texting.

Best UK 2nd phone line for small businesses

Tried so many different telephone apps for my business and this is hands down the best one I’ve come across for the UK. Customer service is also so good, and they’ve helped us with several queries super quickly. Their update earlier this year also was very appreciated and the app works perfectly for my small team to help answer customer’s calls.

Excellent service

Excellent service, we use it for our small business and the ability to share one number with three people is fantastic. Great support desk and very prompt and efficient service.

Simply amazing and cool app

Very intuitive and easy to use. This is the app that stands out from the crowd. A fantastic app for having a separate number for business purposes. Tried so many other apps but finally chose this due to no ads and no hiccups and no issues. Works great with clean interface. Highly recommend this app!

Simple Excellence Acheived

I use Chalkboard for my solo artist salon. I love it because I do not have to share my personal number with guests, and can keep professional boundaries.

I have had to contact Chalkboard several times regarding the A2P 10DLC that is required for business professionals to have by law.

I can not thank you enough. After 15+ years in the service industry, I am fully aware of the importance of excellent customer service, and this company takes it to the extra level. I can honestly say that I have never worked with a team that is so customer service driven and professional. Every single person I have worked with has been kind, helpful, responsive, understanding, knowledgeable, and incredibly attentive. They genuinely want to see you succeed.

Great for small business

Chalkboard is saving my small business hundreds of dollars per year! I recently switched over from Google Voice and have been very satisfied. The only reason I didn't give a 5 star rating is because they don't have a web version of their app - it only runs in native apps on iPhone and Android. The majority of my business is done from a desk, so a web version is a must for me. That said, the savings made it worth leaving Google Voice.

Great tool for small business owners

Incredibly easy to set up, with the ability to broadcast to specific lists of contacts (think mailing list, current/past clients).

Simple, clean interface that has everything you need. I really love the ability to set up a number of automated voicemails/messages, with the ability to create ones for outside of your working hours, holidays etc.

My only issue sometimes is a delay/absence of notifications coming through of new calls or messages

Fantastic app!

The Chalkboard app is perfect for anybody who liaises with customers/ clients/ colleagues etc.. and wants to keep their personal number separate.

The team work hard to bring out new features regularly and is always looking to improve the app for their users.

Amazing Customer Service

The customer service for Chalkboard has been outstanding - I've always received an answer in less than 24 hours and their team has always been eager to help me. My problem or question has always been solved or answered even if it was something I couldn't do. Their team has been happy to help even if it meant working on the back end for something for our small business.
