Final Accounts Preparation Plus

We prepare complete year-end accounts for your clients based on the bookkeeping data you provide. Everything is reviewed for compliance, formatted to your templates, and branded under your firm. Whether you need draft sets for internal review or final accounts ready to file, we ensure your clients' year-ends are wrapped up accurately, on time, and with confidence.

Accounts Review and Adjustments Plus

Our team checks trial balances and supporting schedules to identify any inconsistencies. We apply standard year-end adjustments, prepare lead schedules, and highlight anything unusual. You get clear summaries with proposed entries, helping you finalise accounts efficiently, accurately, and without having to do the legwork yourself.

HMRC & Companies House Submission Support Plus

Once accounts are finalised, we can help you prepare for submission. We make sure formats meet Companies House standards, assist with tagging, and double-check details to avoid last-minute errors. You submit everything under your name and login, while we take care of the admin work in the background.

Corporation Tax Support Plus

If you’re handling CT600s in-house, we provide all the figures and supporting documentation you need to prepare the return. If not, we can help prepare and format tax computations for submission. Our process ensures consistency between accounts and tax, making finalisation faster and cleaner.

Services designed to support your growth

Our year-end accounts process is built to fit around your firm — not the other way around. You stay client-facing and in control while we quietly prepare compliant, accurate accounts in the background.

You onboard the client

You bring the client in, set expectations, and remain the main point of contact. We’ll mirror your processes and work inside your systems.

We handle the books

From daily tasks to reconciliations and reporting, our team manages the numbers behind the scenes — clean, compliant, and up to date.

You focus on growth

With accurate, up-to-date books behind you, you can spend more time advising clients and scaling your firm.

What outsourced year-end accounts actually look like inside a UK firm

Here’s how a fast-growing practice simplified compliance and scaled capacity, without hiring.
The Challenge

Year-end bottlenecks were overwhelming the team. Too many accounts to prepare, review, and file—too little time to do it right.

The Solution

Eccoux took on the full year-end process: drafting, formatting, and filing accounts directly with Companies House and HMRC, all branded to the firm.

The Result

Deadlines met with confidence, zero backlog, and the internal team freed up to focus on client-facing work and higher-value services.
