How project costing works
Create a project with a budget. When saving an expense, choose that project. CostLuma updates actual spend, remaining budget, and a receipt-supported transaction list. Project expense types: materials, labour, subcontractors and other. Set a budget for each cost type, then allocate receipts to the project. For receipts shared by more than one project, record each allocated amount separately.
Settings & backup
Budgets, local data, and transfer options.

Back up your data
Export a JSON backup periodically. It includes transaction and project records plus any receipt photos saved locally. Importing replaces your current CostLuma data.
Privacy and limitations
This prototype stores your information locally in this browser (including receipts). It does not create a cloud account or sync between devices. Clearing website data may delete your records. Receipt recognition requires internet connectivity and loads the OCR library from a third-party CDN when requested; avoid using OCR on sensitive receipts unless you accept that third-party dependency. Images processed with browser OCR stay in the browser with this implementation, but software assets download from external servers. No bank feeds, VAT return preparation, or accounting posting are included. The app does not guarantee correct receipt recognition; always review extracted values.
