MiCA and CASPs: accounting support for your activity
Connect your crypto-asset services with reliable accounting records and financial reporting.
Define your activity
An exchange, a custodian and a company investing its own treasury have different transaction flows. Useful accounting starts with the actual business: who contracts with the customer, who holds the assets, who executes the transaction and who invoices the service? Mapping those roles connects your product’s operations with the correct entity’s accounts.
We review contracts, euro and crypto-asset flows, platforms and available records with your team. The aim is to establish a documented approach, with clear responsibilities and a defined set of supporting records.
You already operate a crypto-asset service
Recurring issues are often operational: linking invoiced fees to transactions, separating customer movements from the company’s revenue, explaining differences between internal and external records, or preparing year-end accounts across several systems. A commercial dashboard may show a large transaction volume without identifying accounting revenue. Each indicator needs a clear definition.
You are developing a new service
Accounting processes are best considered before launch. We can review sample test transactions, export formats and planned invoicing. Your product team can then identify the fields needed: transaction identifier, entity, customer, asset, quantity, fees, timestamp and status. Questions about regulatory classification are coordinated with the relevant advisers.
Your company only holds its own treasury
This situation needs to be distinguished from providing services to customers. If your requirements concern the company’s Bitcoin purchases, custody of its own assets or annual accounts, start with crypto accounting for companies or our holding and treasury support. The assessment depends on the activity actually carried out.
The regulatory position in September 2026
The French transitional period for PSANs ended in July 2026. For the services concerned, check the entity’s authorisation under MiCA and the services it covers. Certain eligible financial entities use the notification procedure under Article 60. Historical PSAN registration alone therefore does not describe a provider’s current status.
Read the AMF’s official transition notice and our guide to checking authorisation.
Prepare a traceable reporting process
Reporting should allow a balance to be traced back to transactions and supporting records. We organise reconciliation between operational ledgers, wallets, exchanges, banks and accounting records. Differences are classified and explained: pending transactions, fees, internal transfers, missing data or timing differences.
An example: customer deposits and service fees
Consider a provider that records customer deposits in its system and charges a fee for a service. Total deposits, amounts to be returned and the provider’s remuneration answer different questions. Combining them into a single “revenue” figure would obscure the business. The accounting treatment must be determined from the applicable rights, obligations and contracts, then connected with the data for each transaction.
Work to organise with your teams
- Flow mapping: entities, products, assets, accounts, wallets and data sources.
- Reconciliation: matching identifiers, tracking fees, checking quantities and resolving unmatched transactions.
- Year-end work: closing balances, supporting evidence, valuation sources and documented accounting judgements.
- Management reporting: distinguishing transaction volumes, revenue, expenses, proprietary cash and operational indicators.
- Traceability: retaining dated exports, applied rules and a record of corrections.
The frequency of this work depends on volume, tools and your organisation. An annual extraction can reveal incomplete histories too late. Regular checks help resolve anomalies as the business operates.
Monitor changes to the accounting framework
ANC Regulations 2026-01 and 2026-02 were endorsed by the order of 12 August 2026, published in the Official Journal on 3 September. For Regulation 2026-01, article 9 provides for financial years beginning on or after 1 January 2027, with early application permitted for the financial year in progress at publication. Review the timetable and your entity’s accounting framework before first application.

Discuss the scope
The first discussion establishes your business model, status, deadlines and organisation. The engagement letter then specifies the agreed work, deliverables, responsibilities and arrangements for providing data.
What should you prepare for an initial discussion?
- A description of the entity and its services, with relevant standard contracts.
- Your regulatory status and the scope of the services concerned.
- The tools, banks, exchanges and wallets used by the business.
- A sample transaction export, an invoice and an example of current reporting.
- The latest available accounts, reporting deadlines and known difficulties.
We start with documents and access appropriate to the engagement. A recovery phrase or private key should not be shared to prepare your accounting file.
Does the firm obtain MiCA authorisation?
The support described here covers accounting, financial data and their organisation. It does not grant regulatory authorisation. Work on regulatory status and requirements must be defined with the relevant professionals, in coordination with your team.
Can we keep our software and accounting team?
The scope can be adapted to your organisation: bookkeeping, review, year-end preparation or specific reconciliation work. We first assess export quality and existing responsibilities. Tool selection follows the assessment of your needs.
How is the budget determined?
It depends on the entities and services, transaction volume and complexity, available data and any historical reconstruction needed. A large, well-documented volume does not create the same difficulties as an incomplete history spread across several tools.
