What is the OneClick Client Portal?

It is a secure area where you can work with us more closely and efficiently. It includes an area for you to upload files to us, and for us to send you files and documents. There is a messaging facility built in too, enabling us to communicate about those documents and files in context.

Where there are documents needing your approval, we can use the Client Portal to upload the documents for you to review, wherever you are in the world, and to approve those documents electronically, improving efficiency and turnaround times.

How does activation work?

When we first enable your client portal, you will receive an email from inviting you to activate your client portal. Please do not respond to the email as it is not monitored.

Instead, please click the activation link within the email, this will take you to an activation page for your oneclick portal account.

When clicking the link it will also send you an activation ID code to your mobile phone, for you to enter as authentication, after which you will be able to set your own password. Along with some security questions so that you can reset your password if you ever need to.

While we have set the minimum security requirements in terms of length and complexity of passwords, you can make yours as complex as you deem appropriate. No record of your password will be held by us. As with all passwords, do not tell anyone or write it down, to protect the security of your portal. You will need your password to login to your account and to approve documents.

How can I be sure my data is safe?

  1. Where and how is our data stored?

We use Microsoft Azure cloud services to host our OneClick platform. All data is stored in Microsoft UK Data Centres (UK South, UK West).

  1. Is data encrypted in transit and rest?

HTTPS is used to provide encrypted communication between customer devices and OneClick.

Communications between OneClick and Third Party services, e.g. HMRC, Twinfield, Xero and Sage also use HTTPS to provide security of data in transit.

Encryption at rest is enabled for all Microsoft products that support it. Within OneClick each customer has their own encrypted Azure SQL database. All files sent in messages are encrypted at rest. Open Integration stores data in Azure blob storage which is also encrypted.

From helping me set up a company to managing my VAT/Corporation tax submissions, has enabled me to grow my business and provide reassurance and advice along the way. The epitome of an approachable expert and equally important, has shown enormous patience over the years as I ask the same questions about VAT every 3 months! I consider them as a trusted adviser and would happily recommend.

Finding an accounting firm who understood, and had first-hand experience dealing with all the intricacies of worldwide VAT and taxation, was a must for us. The entire Argents’ team have been friendly, helpful and professional every step of the way, and we look forward to working with them as we grow and expand with further projects.

I have used them ever since they set up in Norwich for my personal affairs. My company Signs Express has been with them likewise. Although i sold on to the management team, they are still there. I have suggested them to several others both private and corporate and they are all still there. Evidence of service of high quality at a fair price.

Stewart supports my business through the preparation and submission of both my corporation and personal tax services. He is highly knowledgeable and efficient, always willing to offer ad-hoc advice and guidance. I would highly recommend Stewart to help with your accounting needs/QuickBooks adviser. He is great at making the complexity of tax and VAT simple to understand which is important to me.
