Outsourced accounting that delivers 99.8% accuracy — closed by the 15th

Outsourced accounting in Spain involves delegating bookkeeping, financial reporting, and statutory compliance to an external professional firm. Every Spanish limited company (SL/SA) is legally required to maintain accounts in accordance with the Spanish General Accounting Plan (PGC, Royal Decree 1514/2007) and file annual accounts with the Commercial Registry within seven months of the fiscal year-end. Companies subject to the Immediate Supply of Information system (SII) must additionally submit VAT transaction data to the AEAT within four days of each operation.

Outsourced accounting is today the most efficient decision for businesses that want reliable financial information without the cost of an internal department. Our team combines technical rigour with business insight: we go beyond recording transactions — we analyse your financial data to deliver perspectives that drive growth and efficiency.

Accounting is not a bureaucratic formality: it is the nervous system of any well-run business. Up-to-date, correctly classified accounts reconciled monthly let you know at any moment whether your business is making money, where it is losing it, and how your cash position is evolving. Without that information, management decisions are made blind. With it, you can anticipate problems, negotiate with banks from a position of strength, and plan investments with confidence.

We work with businesses across all sectors and sizes, from growth-stage startups to multi-entity groups requiring consolidation. Our service model is built around rigorous monthly closes delivered before the 15th of the following month, with permanent access to dashboards that reflect financial reality in real time. We do not wait for you to ask — we send reports proactively and alert you whenever we detect significant variances from budget or historical trend.

Technology is a means, not an end. We work with leading accounting platforms — Holded, Sage, A3, SAP Business One — and integrate with your invoicing, POS, and ERP systems to automate data capture and minimise manual entry. This reduces errors, accelerates closes, and lets us focus on what creates real value: analysis and interpretation. If you are thinking about coordinated tax optimisation or a company valuation ahead of a corporate transaction, the solid accounting base we build together is the indispensable starting point.

For businesses that want to go further, our outsourced CFO service builds directly on the monthly accounts to provide financial planning, scenario modelling, and support in negotiations with financial institutions. Well-executed accounting is not a cost — it is the foundation on which a resilient, growth-oriented business is built.

Why outsourced accounting matters for your business

Many SMEs reach the end of a quarter without knowing precisely whether they made or lost money that period. Accounting accumulates unreconciled, bank statements do not match the ledger, and VAT or withholding declarations are calculated from incomplete data. The result is a chain of compounding errors: the VAT return does not match the accounts, corporate tax is settled on an incorrect taxable base, and when an AEAT information request arrives the company has no organised supporting documentation. Penalties for discrepancies between accounts and tax filings can reach 150% of the unpaid amount. Businesses that manage their payroll alongside outsourced accounting eliminate these gaps entirely.

Our outsourced accounting process

Our professionals assume the complete accounting cycle with an industrial-precision approach: every invoice posted to the correct account code, every expense classified according to its tax deductibility, every monthly close validated against bank movements before it is finalised. We use Holded, Sage, A3, and SAP Business One depending on each client’s profile, and integrate automatically with invoicing, POS, and ERP data sources to reduce manual input to a minimum. If we detect a discrepancy, we flag it and propose a correction before the month closes. For businesses needing integrated tax filing, our accounting and tax teams work in full coordination.

What our outsourced accounting service includes

The service covers complete monthly bookkeeping (invoices, bank statements, depreciation, provisions), bank reconciliation, monthly close with balance sheet and income statement, quarterly VAT calculation and filing (form 303), withholding returns (forms 115 and 111), corporate tax instalments (form 202), and the annual corporate tax return (form 200). For multi-entity groups the service includes consolidated financial statements with intercompany eliminations. Management reports are delivered before the 15th of the following month via a digital platform with permanent access.

Real results in outsourced accounting

Our clients receive their monthly close before the 15th with 99.8% accuracy verified over three years of service. The rate of AEAT information requests for discrepancies between accounts and tax returns is zero across our active client base. Time that directors spend resolving accounting problems falls by more than 80% from the first quarter. And the ability to present current financial information to banks or investors — previously requiring weeks of preparation — becomes available within 48 hours at any point in the year. If you need a full financial leadership function to complement the accounting service, our outsourced CFO integrates directly with the monthly close to support strategic decisions, financing, and investor reporting.
