Receipt Photo Upload

Photographed receipts are a hard prerequisite for audit-ready reimbursement in HLF's workflow and a strong expectation across the other organizations once expense handling goes digital. Without inline capture, mentors revert to email or paper, defeating the purpose of digitalisation and creating reconciliation work for coordinators. Mobile capture also dramatically reduces lost-receipt incidents and shortens the approval cycle because admins can verify the supporting evidence directly from the approval queue. For accounting integrations (Xledger, Dynamics) the attached image becomes the auditable artifact accompanying each posted expense line.

Implement image capture using a Flutter camera/photo-library plugin, downscale and compress on-device to keep payloads small, and upload to object storage with a signed-URL pattern. Receipt records reference the parent expense ID; the receipt-required threshold is a configurable value inside the expense-reimbursement module so each tenant can set its own limit. Files transit the API backend only for metadata; binary content goes to object storage directly. Offline capture is supported by queuing the upload through the sync outbox. Server-side validation rejects expense submissions that violate the receipt-required rule.
