Fees and how we work
We do not publish fixed fees because every engagement is different. We do explain clearly how we work, which fee models we use and how to get your proposal.
Written proposal
Before starting any engagement we send a detailed proposal with scope and fees. No surprises.
No unagreed charges
Extraordinary engagements are quoted separately, always with your prior approval. We never include unagreed hours.
First consultation free
The initial meeting to understand your situation and assess the engagement is at no cost and with no commitment.

Frequently asked questions about fees
Because the right fee depends on the volume, complexity and scope of each engagement. Publishing a generic fixed fee would mean overcharging simple matters and undervaluing complex ones. We prefer to make a tailored proposal after understanding your actual situation. The first meeting is at no cost.
It depends on the contracted service, but in general it includes: mandatory periodic returns (VAT, IS, withholding taxes), ongoing advisory with no charge per query, alerts on regulatory changes affecting your company, routine contract reviews and handling of minor administrative matters. Extraordinary engagements (complex inspections, M&A transactions, litigation) are quoted separately, always with prior agreement.
Yes. For projects exceeding an estimated volume of hours, we apply a block rate with a discount on the standard hourly rate. We also offer the option of combining an hourly rate with an included hours package, so routine queries are covered and only extraordinary hours are billed separately.
In certain engagements where the outcome is quantifiable, yes: R&D tax incentives (where we recover overpaid tax), tax regularisations with a settlement below the initial AEAT assessment, and M&A transactions where we negotiate price or terms. The success fee is always complementary to a base fee that covers the team's costs.
Both. For SMEs and freelancers with recurring tax and legal needs we offer tailored monthly retainers. For business groups and more complex engagements (M&A, restructurings, tax litigation) the standard model is a fixed-fee project. The client's size does not determine the quality of service — the complexity of the engagement does.
In M&A transactions we combine a fixed process fee (due diligence, structuring, negotiation, closing) with an optional success fee based on the transaction value or the tax saving achieved. The detailed proposal is delivered before the engagement starts and includes a breakdown by phase.
