Build an expense report app named slipjar for a company of about thirty people. Two kinds of accounts: employee and approver. An approver can also submit. EMPLOYEE - Add an expense: date, merchant, amount, category (travel, meals, software, supplies, other), a note, and a photo of the receipt. - Group expenses into a report and submit it. - See each report's status and any approver comments. APPROVER - Queue of submitted reports. - Open a report, see each receipt image, approve or send it back with a comment. - Monthly totals by category and by person. Email the employee when a report is approved or sent back, and approvers when one is submitted. Seed two approvers, five employees, and a dozen reports across statuses with receipt images. Show the seeded logins on the sign-in page. Report status updates in real time.
