I work remotely for a UK company but my family lives in Spain. The work side is fine. The tax side has been a nightmare for years.

Two tax systems. Two currencies. My UK accountant says "talk to someone in Spain." My gestor says "I don't understand the English system." Hacienda wants the ECB exchange rate on the day of the transaction, not the rate my bank gave me. Manually looking up rates for 200+ receipts was hours of my life every quarter.

I looked for software that handles both UK and Spanish taxes. FreeAgent, Coconut — UK only. XOLO, Quipu, Holded — Spain only. Nothing does both.

So I built one. It's an AI receipt scanner that extracts line items, categorises them for both HMRC and Hacienda, and handles the exchange rates automatically. You photograph a receipt and it does the rest.

It's called Forensix — forensix.app. Free tier with 5 scans/month, no card.

I know a lot of people here deal with taxes across multiple countries. I built this specifically for the UK/Spain overlap, but I'm curious — what does everyone else use? Is anyone else just drowning in spreadsheets, or have you found something that actually works?

Solo dev, been building this for 4 months. It's a web app where you photograph a receipt and AI extracts every line item, categorises it for both HMRC and Hacienda tax codes, and handles the GBP/EUR exchange rates automatically.

I built it because I'm between the UK and Spain and nothing on the market handles both tax systems. FreeAgent and Coconut are UK-only. Quipu and Holded are Spain-only. I couldn't find a single tool that does both.

What it does:
- AI receipt scanning (single or batch, handles messy/faded receipts)
- Dual-tax estimates — UK Self Assessment and Spanish autónomo side by side
- Bank CSV import with duplicate detection
- Exports in the format accountants and gestors actually want
- All 17 Spanish regional tax rates built in

Stack: Python, Streamlit, Google Gemini API, Supabase, Stripe, ReportLab.

Free tier (5 scans/mo, no card). Pro £9.99/mo. Expat £19.99/mo.

forensix.app

Tear it apart — UI, pricing, positioning, whatever. I'm one person and I need honest feedback.
