Emerging players

• Holded: Spanish cloud accounting and ERP platform for SMBs and autónomos with integrated invoicing, payroll and tax filing. Competes with Adlanter by offering self-serve alternatives to the firm's labor, accounting and fiscal compliance services for small businesses.
• Declarando: Spanish digital tax advisory platform aimed at autónomos and small businesses for IRPF and corporate tax filing. Competes with Adlanter's smallest-client (self-employed) advisory segment through automated, lower-fee digital delivery.
• TaxDown: Digital-first Spanish tax filing and advisory platform targeting autónomos and SMBs. Directly competes with Adlanter for the same startup/ PYME/ autónomo segment, but delivers services via a SaaS/ mobile product rather than human advisors.

Broad incumbents

• RSM Spain: International mid-tier audit, tax and consulting network with a Spanish practice serving mid-market companies. Comparable to Adlanter in the tax and labor advisory space but oriented toward larger companies and cross-border engagements.
• BDO Spain: Mid-tier accounting and advisory network in Spain covering tax, labor, corporate compliance and outsourcing. Comparable to Adlanter's outsourcing and compliance offering but at a national-network scale with stronger enterprise focus.
• Garrigues: Spain's largest law and advisory firm offering fiscal, labor, mercantile and corporate services. Comparable in the advisory/tax/legal-services space to Adlanter but at significantly larger scale and with a stronger focus on enterprise and corporate transactions rather than SMB integral advisory.
• PwC España: Big 4 professional services firm in Spain offering tax, legal, labor and advisory services overlapping with Adlanter's service portfolio. Competes with Adlanter primarily for mid-market and enterprise clients, while Adlanter focuses more on SMBs, startups and public sector.

Others

• Wolters Kluwer Spain (a3 software): Provider of professional software and compliance tools used by Spanish asesorías and gestorías, including payroll, accounting and tax workflows. Adjacent/ enabling player in the same ecosystem as Adlanter rather than a direct competitor, supplying the technology infrastructure that advisory firms rely on.

Direct peers

• ETL Global Spain: Spanish accounting, tax and labor advisory network with multiple regional offices serving SMBs and mid-market companies. Directly comparable to Adlanter in providing integral fiscal-labor-mercantil advisory through a multi-office model.
• Aura Asesoría: Spanish integral advisory firm providing fiscal, labor, accounting and mercantile services to SMBs and startups. Directly comparable to Adlanter in service mix, target segments (PYMEs, startups, autónomos), and integral (one-stop) advisory positioning in the Spanish market.
