1Office Group Reviews 

I am being scammed by them; I am Brazilian and decided to set up a UK company with them.
I submitted the request and made the payment on August 7th. They sent me a link to complete the KYC process, which I did. About three days later, I asked for a status update, and they claimed I hadn't completed the KYC. I did it again, took a screenshot as proof, and emailed it to them.
To this day, my company hasn't been set up, and they haven't replied to my emails since August 11th.
They left me high and dry and took my money. They are scammers!
Do not hire this company for accounting services, and certainly not to set up your business.
They will likely lie in their Trustpilot responses, claiming they tried to contact me or asked for documents I didn't provide—but that is a lie!
They are scammers!
On the 17th, I am going to report this to the police and file a lawsuit.

I've never encountered an accounting service this disappointed and damaging.

I initially left a 5-star review when signing with 1Office, after calls with Tõnis and Kristine from the sales department. To this day I wonder if they knew what they signed me up to.
My accounting experience since then has been disappointing to say the least.
Despite explaining my business setup multiple times to several team members, I received unclear pricing estimates and incomplete tax guidance. Important tax allowances I’m legally entitled to were never mentioned and only came up after consulting an external accountant.

The lawyer Viire, who was suppose to help me with my legal company name and set up, charged me 93€ for the service, provided via email, and sent me three company name suggestions that were supposed to be legally on the safe side. All 3 names she gave me were already trademarked and I couldn't use them, which lead to a further 2 week delay in my company set up. In the end I did all research myself with the help of Chatgpt and was granted my new company name instantly.
Don't book a lawyer or accounting session with them, it's not worth the money. There are much better services available in Estonia!

More concerning, despite submitting all required documents and monthly reports, my VAT return was running late and I received an official reminder from the boarder control. I had to follow up myself to ensure it was submitted. This happened twice in my 4 months with 1Office.

While my assigned accountant Diana seemed to have tried her best, I never received clear information on my questions, following up several times was the standard procedure for me.
There seem to be serious internal communication issues and inconsistent advice within the team.
In my last month's with the iffice I was blackmailed that I won't receive my company documents unless I pay more money.
I had to hire a new accountant who I paid again to do the work I paid 1office to do.

If you want to live in constant worry of what's going to happen next in your accounting, if you want to feel insulted and treated unprofessionally, 1office is the way to go.
If you do decide to sign with them, ask for a contract and the T&C and make sure they are up to date. Always request your monthly paperwork, so you don't have to worry about any possible set backs/ blackmail later. Put everything in writing, record and transcribe everything and make sure you're on top of it all.

If you want an accountant that's looking out for you, who is available via email and phone, who has your best interest in mind and who treats you like a human being, hire a freelancer!

Absolutely not worth it.
Most expensive and worst accountants I have ever worked with.
Overcharging and negligent.
Go with them if you want to get ripped off and still fined by the Estonian tax authorities.

My experience with Katrin Vija from 1Office was excellent. She was thoroughly prepared and had researched my situation beforehand, making our call regarding my e-Residency status and company highly productive.
Katrin is incredibly knowledgeable and shared valuable, practical tips for the process.

We are very satisfied with 1Office’s services and can highly recommend them to anyone in need of company formation or accounting services.

After finally establishing our office in Sweden, the current support for Accounting is amazing: helpful and very fast. However, in the beginning the set-up was a little unclear sometimes and took for us longer to understand the full process. But now it works great, and I am happy to rely on 1Office for our accounting in Sweden.

I have been using this company for over 3 years and they are fantastic. Very well priced, super service and very patient. My accountant Joseph Dawe is absolutely fantasic and very knowledgable about all issues relating to tax & accounting and i couldn't run my business without him! Highly recommend and will remain a customer for many years to come.

Clear and easy company setup in Estonia. Smooth communication and reliable support throughout.

Scam alert!
Please, do not buy anything from this company. They are unable to open a bank account, which means you won’t be able to register the company in your name or deposit the required share capital.
I’ve wasted so much time — avoid them at all costs!

I’m from the UK and have an Estonian company, and have used 1Office for the last 2 years for Business Reports submission, accounting and some company admin.
The service from Mari (Accountant), Viire (Legal) and Igor (Sales) has been excellent.
Mari provided a lot of support in getting things in order when moving over from my old accountant this year. Igor provided a lot of help with a late request for Business reports submission last year and Viire for some Business Registry updates. The service is very good and professional, you always know the costs up front, and it really feels like the team is always trying to do the right thing on your behalf to ensure the company is compliant, and the books are in order. The team have all been a pleasure to deal with, with perfect written and spoken English, and I would highly recommend 1Office Estonia to anyone considering them.

As a foreign entrepreneur managing a small company abroad, navigating the complexities of local accounting and tax regulations can be daunting. However, 1Office has been nothing short of a lifeline. Their services are exceptionally well-structured, efficient, and truly geared towards making company management as seamless as possible for non-residents.
A special mention must go to Mari Saan, whose professionalism and kindness consistently exceed expectations. Despite the modest size of my company, Mari has always treated my business with utmost care and attention. She is remarkably responsive, proactive, and incredibly knowledgeable in both accounting and broader fiscal matters. Her ability to explain complex procedures in a clear and reassuring way is a rare and invaluable asset.
Mari doesn’t just handle the numbers—she offers genuine support and practical suggestions that make a real difference. Her personalised assistance has given me tremendous peace of mind and allowed me to focus on growing my business, knowing that the financial side is in expert hands.
In a landscape where managing a business abroad can often feel overwhelming, 1Office—and Mari in particular—make it feel straightforward, friendly, and even enjoyable. I wholeheartedly recommend their services to anyone looking to set up or manage a company from abroad. Five stars, without hesitation!

I had a very disappointing experience with 1Office. Their terms of service are unclear, which they take advantage of to charge extra fees. Overall, I do not recommend their service. Save yourself the frustration and look elsewhere for a more reliable and transparent company.

I worked with 1Office during the last 7 years because of a company I opened in Estonia and they are super professionals and very responsive.

I again noticed they haven't taken care of accounting software and I ended up paying a large sum.
Do not trust these business and people.

Through the steps of establishing the company, they've helped me and even though there were technical issues from my side, they still helped me through and directed me to the right option with a full refund. Many thanks especially to Igor Korzun who guided me through the process.

I do not recommend anyone to use this company.

First of all, it has come to my attention, that the person they use as a legal contact person for Swedish companies, has been involved in several money laundering cases, which is a major red flag.

I've been a customer with them for 2 years, and recently sold my company. After the sale, they terminated all the agreements with the new owner (business address, legal contact person and accounting) and asked for a payment of +6000 SEK to make the official changes required in connection to this. Prior to selling my company, i made sure that they would be able to assist me with the registration of a new company as well as accounting and a legal contact person, so i could start my new business in Sweden. They confirmed that they could assist me, but after i sold the company, they notified me that they would no longer be able to provide me with any services.

This puts me in a really bad situation, since i already sold my old business, which included the actual company = i'm no longer able to do business in Sweden.

Stay away from them if you're looking for a serious partner.

Mari Saan is a great professional, responding always fast and accurate on all my demands and was there to help me and my colleagues on our venture. Overall the experience with 1Office was amazing Thank you Mari!

Taissa and her collegaues always tries to help, when I am asking for support. The 1st office try to inform what is going on the next period. The staff at 1st know my question area about liquidation of companies. Their staff are kind in contacts.
