# Memo Barbershop System

A complete operating system for a barber shop chain on a single database: a seventeen-section dashboard, a website, and a customer app. Every pound collected has an invoice, every invoice is bound to a drawer opened under a named person, and the closing breaks down across all four payment methods. Five roles with permissions enforced inside the database itself, sixteen permissions editable from the screen without a developer, and new branches opened by adding a row with no technical setup.

17 sections · 5 roles · 16 permissions · 4 payment methods

## What's inside the system

- Three interfaces on one database: a seventeen-section dashboard, a website, and a customer mobile app.
- The money chain is sealed from opening to closing: reception opens the drawer under their name, every invoice binds to the open drawer automatically — and if the drawer is closed, the system refuses to issue the invoice at all.
- One branch means exactly one open drawer; duplication is impossible.
- The closing is stamped with who closed it, the shift duration, and a net total split across cash, card, InstaPay, and Vodafone Cash.
- Refunds are logged under the requester and held "pending review" until an admin approves, then deducted from net — no verbal refunds.
- Net profit is computed by a formula enforced in the system: revenue minus barber commissions minus branch expenses minus approved refunds.
- Each barber's commission accrues automatically from their actual invoices at their recorded rate, and each barber sees only their own.
- The accounting day follows the shift — 8pm to 4am counts as one day, not two.
- Schedule a full month of shifts at once, with actual attendance compared to the schedule: present, late by the minute, absent — aggregated monthly per barber.
- Live queue management: start service, finish, cancel, mark no-show, and instant booking for a walk-in.
- Five roles — chain owner, manager, reception, barber, customer — each seeing only their own slice.
- Permissions are enforced at row level in the database rather than the interface, so data outside your scope never reaches you even via a direct link.
- Sixteen permissions stored in a table and edited from the permissions screen — no code, no redeployment.
- Every screen is branch-aware by design, so a new branch goes live the same day without a second copy of the system.
- Star ratings and comments after service, with each barber's rating updating automatically from customer reviews.
- Each chain is a fully independent instance with its own data and storage, fully Arabic with RTL across all three parts.

## What you gain

- Revenue closes to the pound: no invoice is issued while the drawer is shut, and no amount moves without a name on it — so any gap between drawer and book has a traceable source instead of vanishing.
- You see net, not gross: revenue is a deceptive number, and the system subtracts commissions, expenses, and approved refunds to give you the real figure daily, monthly, and yearly.
- Month-end commission arguments end: each barber's rate is recorded, commission accrues from their invoices in real time, and the barber sees their own number.
- Pay is computed on reality, not claims: scheduled shifts are compared against actual attendance to the minute, so lateness and absence are documented.
- A shift running past midnight is not split across two days in the books — the accounting day extends with it, preventing wrong numbers in reports.
- Refunds stop being a loophole: they require admin approval, record who asked and who decided, and are deducted from net.
- A new branch is a row in a table: open it and run it the same day with no second copy of the system and no setup from scratch — expansion no longer waits on a developer.
- Permissions are edited on screen: grant or revoke for any role without waiting for a code change or a deployment.
- Staff see only their slice: protection lives in the database, so even a direct link will not surface data outside their scope.
- A real customer base that belongs to you: numbers, visit history, and ratings — not scattered WhatsApp threads.
- Ratings reach you directly, so you know which barber brings customers back and which needs attention — instead of discovering the problem when the customer disappears.
