Feature Comparison

Dokta

AI-Powered Document Analysis

Dokta's core functionality is its advanced AI and OCR processing engine. Upon document upload (photo, scan, or PDF), the system automatically reads, classifies, and extracts key structured data such as document type, total amount, due date, and involved parties in less than 60 seconds. This eliminates manual data entry, ensures accuracy, and instantly converts static documents into actionable items within the platform's workflow, forming a searchable digital archive.

Automated Invoicing & Quote Management

The platform provides comprehensive tools for the billing cycle. Users can create professional invoices and quotes in a few clicks. A standout feature is the ability to send quotes with an online acceptance link, enabling clients to approve digitally, after which conversion to a final invoice is a one-click operation. For freelancers on daily rate (TJM) contracts, Dokta supports automated monthly invoice generation based on the contract terms, streamlining recurring billing.

Real-Time Cash Flow & Anomaly Detection

Dokta offers a centralized financial dashboard that displays key metrics in real time: invoiced revenue, collected revenue, unpaid invoices, and VAT liabilities. This is complemented by a 12-month graphical trend analysis. Proactively, the AI engine includes an anomaly detection system that identifies potential issues such as modified IBAN details, duplicate invoices, inconsistent VAT rates, or missing sequential numbering, providing an essential layer of financial oversight.

Integrated Client & Supplier Database

The platform automatically constructs and enriches a relational database of clients and suppliers by extracting entity details from every processed document. It can perform automatic SIRET number lookup (for French entities) to enrich profiles and includes a payment scoring system based on historical data. This creates a complete, intelligent history per contact, facilitating better relationship management and providing context for all financial interactions.

Pure Tax Investigations

Specialist HMRC Insider Expertise

The firm is led by Amit Puri, a former senior HMRC Tax Inspector with over two decades of direct experience. This provides clients with an unparalleled strategic advantage, as the team possesses detailed, operational knowledge of HMRC's internal methodologies, investigation tactics, and decision-making processes. This insider perspective is applied to anticipate HMRC actions, formulate robust defence strategies, and negotiate from a position of informed strength, ensuring pragmatic and commercially focused outcomes.

Comprehensive Investigation Defence Services

Pure Tax Investigations offers a full-spectrum defence service covering the entire hierarchy of HMRC interventions. This includes managing routine compliance checks, complex cross-tax enquiries into large businesses, and the most serious civil fraud investigations conducted under Code of Practice 9 (COP9). The service encompasses handling HMRC Information Notices, engaging in Alternative Dispute Resolution (ADR), and representing clients at Tax Tribunals, providing end-to-end support throughout the dispute lifecycle.

Proactive Tax Disclosure Management

The firm specialises in managing voluntary disclosures to HMRC through its dedicated disclosure facilities. This includes expert guidance and submission management for the Worldwide Disclosure Facility (WDF) for offshore matters, the Let Property Campaign (LPC) for property income, and disclosures related to crypto assets, Indian interest income, and offshore trusts. This proactive service aims to regularise a client's tax position, minimise penalties, and achieve finality with HMRC before a formal investigation is launched.

Bespoke Advisory for Private Clients & Complex Structures

Beyond investigations, Pure Tax Investigations provides tailored advisory services for private clients with complex affairs. This includes specialist analysis and planning concerning residence and domicile status, UK property tax, trusts, and Inheritance Tax. The service evaluates each client's individual situation to ensure tax affairs are structured efficiently and meet commercial and succession aspirations, providing strategic advice that complements their defensive capabilities.

Use Cases

Dokta

Freelance IT Developer / Consultant

For IT freelancers operating on Time and Materials (TJM) contracts, Dokta automates the entire invoicing pipeline. The system can be configured to generate monthly invoices automatically based on the contracted rate, sending them for one-click validation. This allows the freelancer to focus on development work while Dokta handles payment tracking, sends automated reminders for late payments, and maintains a clear record of all client transactions and project-related documents.

Creative Freelancer / Project-Based Worker

Graphic designers, photographers, and other project-based creatives benefit from Dokta's streamlined proposal-to-payment workflow. They can create a quote and send it via a professional online acceptance link to the client. Upon client approval, the quote is converted to an invoice with a single click. Dokta then manages the payment follow-up, chases late invoices with professional reminders, and keeps all project documents and client communications organized in one place.

Auto-Entrepreneur / Micro-Entrepreneur

This user group requires simplicity and compliance. Dokta generates legally compliant invoices, automatically tracks revenue against the micro-entrepreneur income ceiling, and provides alerts for upcoming URSSAF social charge payment deadlines. The real-time cash flow dashboard gives a clear, immediate view of business health without complex accounting knowledge, and the CSV export feature simplifies year-end accounting procedures.

Growing Small Business (SMB)

Small businesses managing multiple clients, suppliers, and contracts use Dokta as a centralized document command center. The AI processes incoming bills and outgoing invoices, automatically populating the cash flow forecast. Anomaly detection safeguards against fraud or errors, and the automated task generation from documents (e.g., "pay this invoice by X date") ensures no deadline is missed, improving operational reliability and financial control.

Pure Tax Investigations

Defence Against Code of Practice 9 (COP9) Investigations

This use case involves representing clients suspected of serious tax fraud by HMRC's Fraud Investigation Service. Under COP9, clients are offered a contractual opportunity to make a complete disclosure of all deliberate irregularities. Pure Tax Investigations provides critical guidance through this high-stakes process, managing the disclosure, negotiating with investigators, and working to secure a civil settlement in lieu of criminal prosecution, thereby protecting the client's liberty and reputation.

Managing HMRC Compliance Checks and Enquiries

This scenario covers defending businesses and individuals undergoing routine HMRC compliance checks or more detailed enquiries. These can involve questions about tax returns, R&D tax credit claims, or specific transaction details. The firm intervenes to handle all correspondence, ensures client responses are accurate and legally sound, and works to contain the scope of the enquiry to prevent it from escalating into a wider, more intrusive investigation.

Facilitating a Worldwide Disclosure Facility (WDF) Submission

This use case applies to clients with undeclared offshore income or gains who wish to come forward voluntarily. Pure Tax Investigations manages the entire WDF process: conducting a detailed analysis of historical liabilities, calculating tax, interest, and potential penalties, preparing the comprehensive disclosure report, and submitting it to HMRC. This structured approach aims to achieve a final settlement and minimise the risk of a subsequent criminal investigation.

Resolving Complex Corporate Tax Disputes

This involves representing large corporates or sophisticated business entities facing complex, cross-tax investigations by HMRC's Customer Compliance Group or Large Business directorate. These enquiries are often multi-faceted, covering Corporation Tax, VAT, Transfer Pricing, and other areas. The firm provides technical analysis, project-manages the response, engages in specialist negotiations, and utilises mechanisms like ADR to resolve disputes efficiently and commercially.

Frequently Asked Questions

Dokta FAQ

How does Dokta ensure the security and privacy of my documents?

Dokta is built with a strong security-first architecture. All data is hosted on Amazon Web Services (AWS) in Paris, France, ensuring physical and legal data sovereignty within the European Union. Documents and data are encrypted at rest using AES-256 encryption. The platform is fully compliant with the General Data Protection Regulation (GDPR), governing how personal data is processed and stored. No manual access to your documents is performed without explicit consent.

What types of documents can Dokta process?

Dokta's AI engine is optimized to process a wide range of business documents essential for freelancers and SMBs. This includes incoming and outgoing invoices, quotes, proposals, and various types of contracts. The system accepts documents in multiple formats: PDF files, scanned images, and even photographs taken with a smartphone. The AI performs classification to identify the document type before proceeding with precise data extraction.

What happens if the AI makes an error in data extraction?

Dokta is designed for high accuracy but operates on a human-in-the-loop principle for validation. After the AI completes its sub-60-second analysis, the extracted data is presented to the user in an interface for review and confirmation. The user retains full control to correct any field before the data is finalized and integrated into the system. This ensures accuracy while still saving the vast majority of manual entry time.

Can I use Dokta for accounting and tax reporting?

While Dokta is not a certified accounting software, it provides robust features to support accounting and tax preparation. It automatically tracks all invoiced and paid amounts, calculates VAT totals, and allows you to categorize expenses. The key feature is the ability to export all financial data, including client lists, transaction histories, and VAT summaries, into a standardized CSV file format that can be directly imported into most accounting software or provided to your accountant.

Pure Tax Investigations FAQ

What is the main difference between a Code of Practice 8 (COP8) and a Code of Practice 9 (COP9) investigation?

A COP8 investigation is used by HMRC for cases involving suspected tax avoidance or complex technical issues where there is no suspicion of deliberate fraud. It is a civil investigation focused on establishing the correct tax position. In contrast, a COP9 investigation is invoked where HMRC suspects deliberate tax fraud (fraudulent evasion of tax). COP9 offers the taxpayer a contractual opportunity to make a full disclosure and secure a civil financial settlement, with HMRC agreeing not to pursue a criminal investigation for the disclosed offences.

When should I consider making a voluntary disclosure to HMRC?

You should consider making a voluntary disclosure proactively if you have undeclared income, gains, or errors in your tax affairs, especially before HMRC contacts you about them. This is particularly crucial for offshore matters, undisclosed property income, or crypto gains. A voluntary disclosure, managed through the correct facility (like the WDF or LPC), typically results in lower penalties than if HMRC discovers the irregularities first. It also significantly reduces the risk of a criminal prosecution.

How can Pure Tax Investigations help if I have already received an HMRC Information Notice?

An HMRC Information Notice is a formal legal request for information or documents. Ignoring it can lead to significant penalties. Pure Tax Investigations can provide immediate expertise to assess the validity and scope of the notice, advise on your legal rights and obligations, and manage the compliant gathering and submission of information. Their intervention ensures the response is precise and does not inadvertently provide HMRC with grounds to widen the enquiry beyond its original intent.

Do you only handle investigations, or can you provide proactive tax advice?

While Pure Tax Investigations is renowned for its defence and dispute resolution services, it also offers proactive, bespoke advisory services, particularly for private clients and businesses with complex structures. This includes planning around residence and domicile, UK property tax, trusts, and Inheritance Tax. The firm's deep understanding of HMRC's compliance focus allows it to provide strategic advice that is robust and designed to withstand scrutiny, thereby helping to prevent future disputes.
