The problem
PDF invoices arriving through five different channels, data typed in by hand, duplicates that get paid twice and payslips that have to be matched against the bank one by one.
Lab · Administration and documents
Invoice and payslip inbox with evidence
Upload PDFs: data extracted with its evidence, duplicates detected, payslips matched against the bank.
Pilot Controlled pilot in an SME. Payment batches and the connection to the accounting software are still to be tested.
Reading for
Fictional data Everything you see in the demos is fictional: the company «Alisio», the people, the amounts and the documents. Nothing leaves your browser. The interactive demos keep their interface in Spanish, as built.
For management
What it does
- Every PDF is given a fingerprint: a duplicate is detected even if the file name changes.
- Tax ID, number, date, net amount, VAT and total extracted, each with its evidence in the document.
- Supplier recognised by its aliases.
- On approval, a copy is archived under a standardised name; the original is left untouched.
- Payslips: the month's PDF is split by person and matched with the bank transfer.
What you gain
- Less typing and fewer errors when recording invoices.
- No duplicate payments through oversight.
- Payroll evidence ready for audits and grant claims.
Try this
- Select an invoice and hover over the data: the evidence lights up.
- Open the invoice flagged as a duplicate.
- Approve one and look at the name it is archived under.
- In «Nóminas» (payslips), review the weak-rule warning.
For IT leadership
How it is built
- Local web application (FastAPI + PostgreSQL) published through Cloudflare Tunnel; local OCR with Tesseract.
- Rule-based extraction; reprocessing with an AI model only if it is switched on.
Security
- SHA-256 fingerprint per document and an immutable original.
- Data does not leave the office unless the external model is switched on; the system warns if configuration is missing.
- Protected access; Cloudflare Access is mandatory to expose it permanently.
Use of AI
External AI switched off by default; when it is used, every proposed value keeps its evidence and is approved by a person.
Operations
Separate CSV exports of invoices and payments for the external accountants.
Built for the administration team of a group of SMEs.
