USD $49 Odoo 18 Inventory OPL-1

Prevent Negative Stock

Stop accidental overselling from internal stock. Clear errors, flexible exceptions,
and visibility before the balance goes negative.

USD $49 — one-time purchase, no subscription.

49 دولاراً أمريكياً — شراء لمرة واحدة، بلا اشتراك شهري.
يمنع صرف كمية أكبر من المتوفر حتى لا يصبح رصيد المخزون سالباً؛ مع استثناءات يمكن ضبطها (فئة، مستودع، أو موقع). يوفر أيضاً لوحة تنبّه للمنتجات التي وصل مخزونها إلى حد تنبيه تحدده أنت (مثلاً: عند 5 وحدات أو أقل)، وتنبيهات اختيارية لمديري المخزون.
✓
Validation-time guard Blocks the move when the quantity is not there—before stock goes negative.
⚙
Exceptions that fit real ops Per category, warehouse, or location—only where you allow it.
◎
Audit & early warning Log of blocked attempts, low-stock view, optional manager activities.

Why it matters

Fewer surprises at the loading bay

When a delivery is validated from an internal location, standard Odoo can still let the on-hand balance drop below zero. This module enforces your policy at validation: if the stock is not there, users see a direct message—product, location, and quantities—so teams fix the issue instead of chasing phantom stock.

🛡️

Protect revenue & trust

Reduce promises you cannot ship and the firefighting that follows a negative balance.

🎯

Rules you control

Strict by default; carve out categories or locations where negative stock is still acceptable.

📋

Accountability built in

Blocked attempts are recorded; a risk-style list highlights lines near your chosen alert level.

Odoo 18 stock + mail Low-stock view Blocked attempts log Scheduled manager alerts

Details

What you get in the app

  • Outgoing moves from internal locations are checked before completion.
  • Disable the check only where it makes sense: product category, warehouse, or single stock location.
  • Failed validations are stored for review (stock.no.negative.log).
  • A read-only dashboard highlights lines at or below your warning threshold (stock.no.negative.risk).
  • An hourly scheduled action can create warning activities for stock managers—nudge inside Odoo without inbox noise.

دليل تجربة سريعة

مثال عملي يمكن اقتباسه أو تعديل أسماء المنتجات والكميات حسب بيئتك.

أولاً: تجهيز الفئات والمنتجات

  1. فئة تمنع السالب: من Inventory → Configuration → Product Categories أنشئ فئة باسم Test – Block Negative، عطّل Allow Negative Stock، وحدّد حد التنبيه = 5.
  2. فئة تسمح بالسالب: نفس المسار، فئة Test – Allow Negative مع تفعيل Allow Negative Stock.
  3. منتجان: A: Product-BLOCK على الفئة المانعة، B: Product-ALLOW على الفئة المسموحة.
  4. مخزون ابتدائي: عبّي لـ Product-BLOCK مثلاً 3 وحدات، واترك Product-ALLOW على صفر.

ثانياً: السيناريوهات

  1. حظر: صرف 5 وحدات من Product-BLOCK (الرصيد 3) — النظام يرفض ويعرض رسالة.
  2. نجاح: صرف 2 وحدات من Product-BLOCK (الرصيد 3) — يمر والرصيد يصبح 1.
  3. فئة مسموحة: صرف 10 من Product-ALLOW (الرصيد 0) — يمر رغم الرصيد السالب.
  4. تجميع: سطران 1.5 + 2.0 من Product-BLOCK (الرصيد 1) — يُحسب المجموع 3.5 ويُحظر.
  5. تجاوز المستودع: فعّل Bypass على WH ثم جرّب صرفاً فوق الرصيد — يمر.
  6. تجاوز الموقع: نفس الفكرة على موقع التخزين الداخلي بدل المستودع كامل.

ثالثاً: السجل، اللوحة، والتنبيه

  1. من Inventory → No Negative Stock → Blocked Attempts يمكنك مراجعة محاولات الحظر.
  2. Risk Dashboard يعرض الأصناف التي وصلت إلى حد التنبيه أو دونه.
  3. من Scheduled Actions شغّل «Negative Stock Risk Notifications» يدوياً لمعاينة أنشطة التحذير.
