Commissa Quickstart, as shipped in the download

COMMISSA — QUICKSTART
=====================

Self-hosted sales-commission calculator — PHP + MySQL/SQLite. Computes what your
reps are owed. It moves NO money (no payment processing, no cards, no crypto).


REQUIREMENTS
------------
  - PHP 8.1+ with extensions: pdo, pdo_sqlite (or pdo_mysql)
  - MySQL 5.7+ / MariaDB 10+ OR SQLite 3 (SQLite requires no extra setup)
  - A web server (Apache with mod_rewrite, or Nginx with try_files)
  - No Composer packages, no API keys, no external services.


SHARED HOSTING / CPANEL (RECOMMENDED FOR MOST BUYERS)
------------------------------------------------------
1. Upload the contents of the `app/` folder to your web root (e.g. public_html/)
   or a subdirectory (e.g. public_html/commissa/).

2. Make sure this directory is writable by PHP:
     data/
   Via cPanel File Manager: right-click -> Permissions -> set to 755 or 775.

3. Visit https://yourdomain.com/install/ in your browser.

4. Fill in the installer:
     - Database: choose MySQL (fill in host/name/user/pass) or SQLite (no setup)
     - Business name, currency, timezone
     - Your admin name, email + password

5. The installer writes config.php, creates a starter global 5% flat rule, and
   redirects you to the login page.

6. Log in, then:
     - Add your reps
     - Set up commission rules under Setup > Commission rules
       (flat, tiered, or per-category; global or per-rep, with effective dates)
     - Record deals (mark each won or pending)
     - Create a pay period and open it to see each rep's payout; open a rep's
       statement to print/PDF/CSV it and add bonuses or clawbacks.


TRY IT WITH DEMO DATA FIRST
---------------------------
  - On the dashboard, click "Load demo data" for a sample team with a tiered
    scheme whose bands a rep's deals straddle, then "Reset all data" when done.
  - Or from the command line:  php bin/demo.php
      (login: admin@commissa.app / admin123)


VPS / SELF-HOSTED (APACHE)
--------------------------
  <VirtualHost *:80>
    DocumentRoot /var/www/commissa/app
    <Directory /var/www/commissa/app>
      AllowOverride All
      Require all granted
    </Directory>
  </VirtualHost>


DOCKER (QUICK TEST)
-------------------
  docker run --rm -p 8080:8080 \
    -v "$(pwd)/app:/var/www/html" \
    -w /var/www/html \
    php:8.3-cli \
    php -S 0.0.0.0:8080 router.php

  Then visit http://localhost:8080/install/


HOW COMMISSION IS COMPUTED
--------------------------
  - FLAT: one rate on every dollar of a rep's won sales.
  - TIERED: progressive bands on the rep's cumulative won volume in the period
    (like tax brackets). A deal that crosses a band is split across the bands to
    the cent, and the statement lines always sum to the period total exactly.
  - PER-CATEGORY: a rate per product/category, with a default for the rest.
  - A rep-specific rule overrides the global default; the latest effective date
    on/before the period wins.
  - Net payout = gross commission + adjustments (bonuses +, clawbacks -).


REPORTS & EXPORTS
-----------------
  - Open a pay period to see every rep's volume, gross, adjustments and net.
  - Open a rep's statement to Print / Save-as-PDF, download a genuine PDF, or a
    CSV (formula-injection hardened, safe to open in Excel / Google Sheets).
  - The whole-period CSV lists one row per rep.


POST-INSTALL SECURITY CHECKLIST
--------------------------------
  [ ] config.php is protected (the .htaccess does this automatically)
  [ ] data/ is not web-accessible (.htaccess blocks it automatically)
  [ ] Use HTTPS in production
  [ ] Keep PHP updated


NOTES
-----
  * Money is stored as integer cents; rates as integer basis points. No floating
    point ever touches a total.
  * Commissa computes commission owed. It is NOT a payment processor and never
    handles cards, bank transfers, or cryptocurrency. Settle payouts via payroll.
