Shaky start

I went to try sleek rather than continue to do my own books and accounts.
Sam the sales rep made many promises that the switchover would be painless and only take 5-6 days to swap everything over from QuickBooks onto Xero.
We set up 2 company accounts with sleek and 3 months in we are still not up to speed and caught up with everything.
This has cost additional monies as we have had to subscribe to QuickBooks for an additional few months as well as pay Sleek.
We are now catching up with one company after me chasing a bit and complaining but the other company is way behind.
I am hoping it will improve soon and these are just teething problems on a new account or we will have to consider moving everything on again which is hard work.
I had a productive chat with Chloe the accountant and the payroll guy but the bookeeper seems to be the issue. Either they are new or just overwhelmed with work and not keeping up.

Hi Lindley Chambers!

We truly appreciate your detailed feedback and completely understand your frustration with how the onboarding and migration process has unfolded. You’re absolutely right — the experience so far hasn’t reflected the high standards we set for ourselves at Sleek, and we take full accountability for that.

After reviewing the situation, we can confirm that your migration has indeed been more complex than initially anticipated, largely due to the number of transactions, multiple bank accounts, and discrepancies in how Stripe sales were recorded. These details weren’t apparent to the sales team at the beginning, which led to unrealistic expectations around the timeline.

Please rest assured that your migration is now being handled directly by a senior team member, with Chloe your account manager overseeing the process to ensure accuracy and completion as soon as possible. We genuinely value your patience and understanding as we work to finalise everything properly and get your companies fully up to date.

Sleek tax preparers are the best!

Sleek’s communications are friendly, effective and timely. After an early email to check my readiness they accepted and respected my timeline and were ready to go when I was. My Tax Manager, Toby Denwood, was extremely helpful and focused on my particular situation, asking key questions and checking for clarity. The signing and submitting processes were simple and smooth, unlike experiences I had with other preparers. Thoroughly satisfied and will recommend without reservation.

Sleek offer great support and experience for a new company

I set up my own company last year and was looking for a reliable, knowledgeable but cost efficient accountant and did plenty of research into local and national companies.
After realising how expensive they can be for first time, small companies I looked at online only accountants whose costs were much cheaper. I was sceptical at first about any of them but settled on Sleek as the preferred one and I haven’t looked back. They are great honestly, even though they aren’t based in the UK they are completely knowledgable, experienced and more than helpful with any advice you need.
My senior accountant Abu (Mohamed Abubuckar) and the supporting team (who are always copied into emails for additional support) is fantastic. He responds quickly to email queries, keeps on top of all my accounting issues and our quarterly catch-up meetings and seemingly can’t do enough to support me and my business.
I can’t recommend sleek enough if you are starting out and need that level of support.
