We help companies solve complex challenges with one team combining audit judgement, regulatory expertise and technology execution.
From financial statement audit to the delivery of complex regulatory and digital solutions — we combine financial expertise, tax methodology and technology so that financial, tax and digital challenges work as a unified system.
Financial statements are not prepared in the final spreadsheet. They are produced by accounting systems, integrations, controls and data flows.
Our team is trained to understand how information originates, changes and flows into the financial statements.
We build solutions for accounting, compliance and data work based on verifiability, controllability and transparency.
We align business processes, accounting methodology and IT solutions into a unified system of requirements — without losing meaning between finance and development.
Projects are led by specialists who understand the task, business context and management expectations.
Experience in complex audit and consulting projects across industries sets our standard.
The combination of our own accounting and development teams gives LUCAS technological capabilities unusual for the market.
We don't limit ourselves to individual services — we build solutions around the client's tasks in accounting, taxation and digital finance transformation.
Financial statement audits, IFRS reporting and accounting advisory services for companies, owners, banks and investors. Audit and non-audit services are provided separately, in line with independence requirements.
The practice is led by partners and senior professionals with Big 4 backgrounds, including audit, quality management and methodology leadership.
Mandatory financial statement audit for PIEs, large and medium-sized enterprises — with enhanced requirements for auditor independence, engagement quality, procedure documentation and auditor's report format.
Audit of consolidated financial statements of holdings — with review of eliminations, intergroup transactions, and preparation of group audit instructions for component auditors.
Limited assurance engagements (review), agreed-upon procedures and confirmatory letters for banks, investors or partners — where a full audit is not required.
Preparation of financial statements under IFRS — for financing purposes, parent company requirements or internal management. Provided to clients we do not audit.
First IFRS financial statements (IFRS 1), accounting policy methodology, and transformation of existing national standard statements into IFRS format with disclosures and notes.
Preparation of group reporting packages to parent company requirements — in specified formats, with elimination adjustments and intergroup transaction disclosures.
A proprietary, ERP-independent platform for extracting, mapping, validating and generating SAF-T UA XML files at scale.
The financial side of SAF-T projects is led by the audit practice leader (ex-EY), and development by an architect of complex technology solutions with many years of experience designing and delivering large-scale systems in Ukraine and the US.
Unlike solutions tied to one ERP, SAF-T Connector connects to SAP, 1C/BAS, Odoo, Microsoft Dynamics, and any custom systems, and can work with multiple sources simultaneously.
The algorithm is written in Python and processes high-volume transaction data significantly faster than most solutions built into accounting systems. A key advantage for companies with big data.
Automatic XSD validation and additional check layers. Each error is explained in plain language. Result — SAF-T UA XML file generated per current STS structure and technical requirements, with preliminary data validation.
System installed on client server. No cloud uploads or third-party data transfers. The solution does not require internet access to operate.
Client provides data access — then LUCAS works autonomously, discussing specific questions with the client. Typical implementation timeline — 3–4 months, depending on data sources, data quality, and client responsiveness.
When one vendor supplies the product and another implements it, responsibility often gets diluted. LUCAS provides a single accountability point for the solution, implementation and practical result.
LUCAS provides the full implementation cycle with competitive total cost of ownership. Our well-practiced implementation process means work moves faster, with a clear structure and lower total cost.
Transition from Russian software to a modern ERP platform — with focus on accounting methodology, correct data migration and reporting compliance from day one.
Our Odoo ERP migration team has deep practical experience implementing Odoo for companies in Ukraine, Europe and North America, with comprehensive understanding of system architecture, modules, integrations and business processes.
Restrictions on defined software products apply to government bodies, state enterprises and critical infrastructure (Cabinet Resolution №1335). For the private sector — restrictions through NSDC sanctions lists. Draft law №13505 provides for fines up to 2% of annual turnover. Using 1C/BAS may raise additional questions from banks, international financial institutions, donors and investors in compliance and cybersecurity assessments.
Odoo coverage — 175 countries, 15 million users, doubling every year. Toyota, Nokia, Nestlé, Airbus, Danone — among clients. One subscription covers 30+ modules: accounting, CRM, warehouse, manufacturing, HR, and more.
Transparent license covering all Odoo apps, no hidden fees. Thousands of ready-made connectors and a huge developer community instead of expensive custom development and single-vendor dependency.
Our teams understands local accounting and reporting requirements — so system design starts from the right accounting assumptions.
Misunderstandings between finance teams and developers are the main source of delays and overruns in any ERP project. Our accountants and developers work as one implementation team. This saves 30–40% of implementation cost.
Analysis → Architecture → Customisation → Data migration → Testing → Go-live. Parallel accounting until correctness confirmed. Team training and support transition included.
