Management accounts, not just year-end

Spanish accounting requirements are not optional, and they are not simple. Companies must follow the Plan General de Contabilidad (PGC), file annual accounts with the Mercantile Registry, maintain official journals, and reconcile bookkeeping with quarterly tax filings. For non-resident owners and international groups, the picture gets more complex: consolidated reporting, related-party documentation, transfer pricing, and currency considerations all sit alongside the standard requirements. Fideso handles all of it — and translates it into reports you can actually use.

Bookkeeping & Daily Accounting

Recording of all transactions in line with the Spanish General Accounting Plan (PGC), bank reconciliations, supplier and customer ledger management, and digital archiving of supporting documents. Handled monthly, not annually, so your records stay current.

Annual Accounts & Mercantile Registry Filings

Preparation and deposit of annual accounts (Cuentas Anuales) at the Mercantile Registry, including balance sheet, profit and loss, statement of changes in equity, cash flow statement where required, and management report. We handle the legalisation of official books (Libros Oficiales) at year-end.

Management Reporting

Monthly or quarterly management accounts in your language and format of choice. We build dashboards that show what the statutory accounts cannot — margin by line, cash position, fixed cost coverage, and the metrics that matter to your business.

Consolidated & Group Accounting

Consolidation for Spanish entities within international groups, including intercompany eliminations, foreign currency translation, and reporting packages aligned with parent company requirements (IFRS, US GAAP, or local frameworks).

Audit Support & Coordination

Preparation of audit files, liaison with Spanish auditors, and resolution of audit queries. Whether your audit is statutory, group-required, or due-diligence-driven, we ensure the working papers are ready and the answers are defensible.

Self-Employed & Freelance Bookkeeping

Income and expense ledgers, investment goods register, and intra-community operations records for autónomos and freelance professionals — fully aligned with quarterly Modelo 130/131 and annual Modelo 100 filings.

Accounting connects to everything else

Your books are the foundation for tax filings, payroll reconciliation, and wealth structuring decisions. Fideso integrates accounting with our tax, payroll, and legal teams so the same numbers flow through every filing — no reconciliation gaps, no surprises at year-end.

Bring your books in line — and keep them there

Whether you're starting fresh, switching from another firm, or cleaning up after a difficult year, we can take it from here.
