Mobile Quality Inspection & Photo Defect Evidence Logging: Real-Time Vendor Scorecards in Odoo

1. The Friction of Disputed Vendor Quality Rejections

When raw materials arrive at factory receiving docks, quality inspectors perform physical sampling. In traditional setups, if an inspector finds that 15 corrugated boxes in a bundle have broken fluting or that machined flanges have surface rust, they write a manual rejection report.

Days later, the purchasing manager contacts the supplier to request a debit note. The supplier vehemently disputes the claim: 'Our material was perfect when dispatched; your warehouse must have mishandled it or your inspector made a mistake!' Without photographic proof and timestamped inspection evidence, management is forced to absorb the loss.

2. ISO 2859-1 AQL Sampling & Mobile Evidence Workflow

The mobile quality inspection application standardizes incoming acceptance:

Inspectors use the mobile app to scan the Goods Receipt Note, enter measured parameters, capture camera photos of defective samples, and mark rejections with 1-tap simplicity.

3. Production Odoo 19 Python ORM Quality Evidence Blueprint

Below is the Odoo model binding photo evidence and automated vendor debit generation:

# -*- coding: utf-8 -*-
from odoo import models, fields, api, _
from odoo.exceptions import UserError

class QualityCheckMobileEvidence(models.Model):
    _inherit = 'quality.check'

    defect_photo_ids = fields.Many2many('ir.attachment', string="Defect Photographic Evidence")
    sample_size_tested = fields.Integer(string="AQL Sample Tested")
    defects_count = fields.Integer(string="Defects Identified")
    vendor_debit_amount = fields.Monetary(string="Estimated Penalty / Debit", currency_field='currency_id')
    currency_id = fields.Many2one('res.currency', default=lambda self: self.env.company.currency_id)

    def action_reject_with_evidence(self, debit_amount):
        """
        Rejects batch, locks quants, and notifies vendor with attached photo evidence.
        """
        self.ensure_one()
        self.write({
            'quality_state': 'fail',
            'vendor_debit_amount': debit_amount
        })

        # Generate internal chatter log with photographic attachments
        self.message_post(
            body=f"REJECTED: Batch failed quality inspection ({self.defects_count}/{self.sample_size_tested} defects). Debit Note of ₹{debit_amount:.2f} prepared.",
            attachment_ids=self.defect_photo_ids.ids
        )
        return True

4. Objective Vendor Rating Scorecard

Every inspection result automatically updates the vendor's cumulative quality score in Odoo. Purchasing agents immediately see whether a supplier maintains a 99% or 88% acceptance track record before placing future procurement orders.

5. Implementation & Cost Recovery

Mobile photographic QC eliminates supplier disputes, guarantees 100% recovery of rejection costs, and elevates supply chain quality across enterprise manufacturing units.
