Conta Labs builds the AI agents that read, reconcile, and post journal entries — so accountants can spend their time where it matters: advising clients and growing the relationship.
Each agent completes a real task end-to-end — reading the document, making the entry, reconciling the line, drafting the message. Every action logged. Every decision auditable.
Ingests every receipt, invoice, and document your clients send — WhatsApp photos, PDFs, scraped from Portal das Finanças — understands it and stores the extracted data in your chart of accounts. No templates. No rules to maintain. Works across formats and languages out of the box.
Matches bank statement lines to invoices, receipts, and supplier documents across multiple entities and currencies. Connects through PSD2 to read accounts directly; flags exceptions for the human accountant rather than guessing. The match logic is shown, not hidden.
Learns your firm's historical posting logic, applies Portuguese tax rules (IVA, IRC, IRS) natively, and drafts journal entries ready to post into TOConline, Primavera, CentralGest or your software of choice. Every decision carries a natural-language rationale.

Handles the back-and-forth that eats half an accountant's day: chasing missing receipts, asking about a new vendor, confirming a category. Drafts in clear Portuguese (or English), waits for the human's approval, then sends. Closes loops without losing the relationship.
Agents are only put into production once they clear our internal accuracy bar. Your team handles exceptions, not the bulk.
Real-time reconciliation and posting. Books that used to take three weeks close in days.
Nothing posts without the accountant's review. The agent drafts. The human approves.
Every agent action is logged with a natural-language rationale. Always audit-ready.
We don't compete with TOConline, Primavera, CentralGest or your ERP. We sit on top of them — reading documents, drafting entries, calling their APIs to post the work. Proof-of-concept in two weeks. Full integration in four.
Your firm owns the data. Our models never train on it. Every action is auditable.
Models never use your data for training. Customer data is logically segregated per firm and per entity.
Hosted in EU regions, run from Lisbon. Compliant with GDPR, AT obligations, and Portuguese accounting regulations.
Every action by every agent has a timestamp, an input, an output, and a rationale. Inspect any decision.
Technology earns its place when it unlocks better client service. Our agents handle the operational layer end-to-end, with traceable reasoning, so the human team can spend their time where it matters.
