Everything a trades business needs. Nothing it doesn't.

// outgoings scanner · step by step
From phone snap to accountant-ready export.
No manual entry. No lost receipts. No end-of-month panic.
Step 01
📸
Engineer snaps the receipt
On their mobile browser — no app install. Photo uploads to your secure Backblaze B2 cloud bucket.
Step 02
🤖
AI reads every line
Every 30 minutes, a Python script sends unprocessed receipts to GPT-4 Vision. Supplier, date, line items, VAT, total — extracted to structured JSON.
Step 03
📊
Office sees it instantly
The JSON posts back to your WordPress site via API. The outgoings log updates in real time — categorised, searchable, filterable.
Step 04
📤
Export to Xero or Sage
One click generates a CSV in the exact import format your accountant needs. No reformatting, no errors, no calls asking "what's this receipt for?"
