Dokta
Instant AI Document Analysis
This is the brilliant core of Dokta. Forget manual data entry. You drag and drop a photo, scan, or PDF of any invoice, quote, or contract, and in under 60 seconds, the AI performs OCR and intelligent classification. It doesn't just read text; it understands the document type, extracts the amount, due date, client or supplier details, and populates your system. This feature alone can save hours per week and eliminates the risk of human error from manual transcription.
Automated Invoicing & Quote-to-Invoice Workflow
Dokta moves beyond analysis into creation. You can generate professional invoices and quotes in clicks. For freelancers on day-rate contracts, it offers automatic monthly invoicing. But my favorite part is the online quote acceptance: send a quote with a link, the client accepts it online, and you can convert it to a finalized invoice with a single click. This seamless flow from proposal to payment is a game-changer for project-based work.
Real-Time Cash Flow & Anomaly Detection
Dokta provides a crystal-clear, visual dashboard of your financial health—invoiced revenue, collected revenue, unpaid amounts, and VAT—with a 12-month graph. More impressively, its AI acts as a guardian. It proactively detects anomalies like changed IBAN numbers, duplicate invoices, inconsistent VAT, or missing numbering. This protective layer is invaluable for avoiding costly mistakes or fraud.
Intelligent Client Database & Automated Reminders
Every document you process automatically enriches a centralized client and supplier database, complete with SIRET-based information. Dokta assigns payment behavior scores, giving you insight at a glance. Crucially, it automates the awkward but necessary task of chasing late payments by sending polite, professional payment reminders for you, saving you the stress and preserving client relationships.

Simplicity and compliance are key here. Dokta generates compliant invoices, tracks collections against the URSSAF ceiling (a critical feature in France), and sends alerts for contribution deadlines. It demystifies financial tracking for the solo operator, eliminating the stress of manual calculations and potential errors come declaration time.
