We work with your team to identify which of your clients' projects qualify for R&D tax relief, diving deep into their technical activity, objectives, and uncertainties. Our experts ensure every claim is based on HMRC’s latest criteria, while keeping the process simple and low-lift for your firm. No guesswork, no wasted time — just clear guidance to maximise the value of every claim.

Once qualifying work is confirmed, we prepare comprehensive technical reports and financial breakdowns for each client. We follow your firm’s workflows, templates, and tone of voice to produce fully branded reports that look and feel like your own. Every submission is reviewed to ensure accuracy, compliance, and audit readiness — all without adding pressure to your internal team.

Before any claim is finalised, we run a full compliance check across both the narrative and financials. Our specialists ensure that every claim stands up to HMRC scrutiny, flagging potential risks and ensuring claims are both robust and optimised. This gives your firm peace of mind, knowing every submission is complete, accurate, and defensible if challenged.

Should HMRC request additional information or clarification, we support your firm behind the scenes. From handling technical questions to providing detailed breakdowns, we stay aligned with your systems and workflows to ensure the claim stays on track — while you stay in control of the client relationship.
Services designed to support your growth
You stay client-facing and in control while we prepare technical narratives, calculate claims, and handle compliance in the background.

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

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

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

What outsourced R&D tax credit support actually looks like inside a growing UK firm
Clients were eligible for R&D tax credits, but internal teams lacked the time and technical knowledge to handle claims in-house. Risk of missed opportunities and compliance concerns were growing.
Eccoux stepped in to manage the full claims process — from eligibility reviews to report preparation and submission. All documentation was reviewed, HMRC-ready, and delivered under the firm’s brand.
R&D claims were submitted on time, clients saw improved cash flow, and the firm built new revenue streams — without hiring or overloading internal teams.
