Make Every Incoming Material Inspection Traceable.
Inspect incoming lots on the factory floor, capture defects with photographic evidence, apply sampling rules, and push the final quality decision into Odoo—without relying on handwritten inspection reports.
Quality Problems Don't Start With the Supplier Dispute. They Start With Missing Evidence.
When raw material rejections fail on the commercial front, it is almost never because the defect wasn't real. It fails because the physical evidence was never mathematically locked to the ERP purchase order at the receiving bay.
The Fragmented Paper Workflow (Before)
The 9 Unanswerable Audit Questions
When a vendor disputes a ₹2,50,000 rejection debit note, executive management routinely asks these 9 questions—and paper systems collapse:
Follow One Lot: From Truck Unloading to Vendor Scorecard
Rather than treating mobile QC as an isolated camera app, trace how a single shipment of 5,000 machined flanges moves through 14 continuous operational and ERP states.
STEP 01 Physical Truck Arrival
Delivery vehicle parks at receiving bay 02. Goods delivery challan presented to receiving gate clerk.
STEP 02 GRN Optical Scan
QC inspector opens mobile app, scans the 2D QR code on the Goods Receipt Note (`GRN-00871`).
STEP 03 Lot Identity Verified
App queries Odoo ORM in real time to verify supplier, item code, heat number, and total quantity (5,000 units).
STEP 04 AQL Sampling Calculated
Engine computes required sample size under ISO 2859-1 Level II normal inspection: 200 random units.
STEP 05 Physical Sampling
Inspector draws 200 units across 10 different corrugated master cartons to ensure statistical integrity.
STEP 06 Defect Detected
During visual and dimensional inspection, sample #84 reveals severe localized surface oxidation and pitting.
STEP 07 Photo Evidence Captured
Inspector triggers high-res macro camera within app. Macro viewfinder records image with uneditable metadata.
STEP 08 Digital Vernier Recording
Bore diameter measured at 119.82mm against 120.00mm ± 0.05mm tolerance; actual values logged to inspection line.
STEP 09 Quality Decision Made
Total defects count reaches 6 units (exceeding acceptance threshold of 5). App marks state as `REJECT / REVIEW`.
STEP 10 Material Quarantined
Physical red quarantine tags printed instantly from mobile Bluetooth printer. Lot moved to locked quarantine zone.
STEP 11 Odoo Real-Time Sync
Odoo `quality.check` marked `fail`. ERP automatically locks `stock.picking` from moving to production inventory.
STEP 12 Automated Vendor Alert
Odoo generates automated rejection notification with embedded defect photographs sent to vendor's QA head.
STEP 13 Draft Debit Note Prepared
ERP drafts vendor debit note in Odoo Invoicing based on rejected quantity and PO contract unit price.
STEP 14 Scorecard Updated
Vendor's rolling quality acceptance rate drops from 98.2% to 96.8%. Purchasing team sees updated risk score on next PO.
Visual AQL Sampling: Removing Guesswork From the Dock
Traditional receiving inspectors either check 5 units and assume the lot is good, or spend 4 hours inspecting every piece. The mobile application embeds ISO 2859-1 (Normal Level II) sampling algorithms directly into the inspector's hand.
The Mobile Inspector Experience: 9 Guided Steps
Field quality software fails when it mimics a complex desktop ERP form. The Arihant AI Flutter mobile interface simplifies dock work into 9 focused touchscreen tasks designed for industrial gloves and sunlight legibility.
Today's Inspection Queue
Inspectors see their prioritized dock workload with real-time sync from Odoo warehouse receipts.
Optical GRN / Challan Scan
Camera barcode engine scans 1D Code128 or 2D QR codes on challans in under 300 milliseconds.
Validated Lot Details
Direct lookup into Odoo `purchase.order.line` prevents inspecting mismatched or unordered parts.
Live Sampling Counter
Interactive clicker increments inspected samples; prevents premature lot sign-off before sample quota is fulfilled.
Tolerance Checklist
Standardized parameters with pre-configured upper and lower engineering tolerance bands.
High-Res Camera Capture
Custom in-app camera viewfinder optimized for poor warehouse lighting with automatic illumination.
Defect Pin & Annotation
Touchscreen finger drawing allows inspectors to circle defects and attach standardized defect category tags.
Disposition Decision
Tri-state decision engine with confirmation popups requiring senior supervisor PIN for overrides.
Inspection Complete & Synced
Automatic cryptographic payload generation pushed via REST API into Odoo ERP backend.
Turn a Defect Into Evidence: The Forensic Quality Record
A standalone photograph on a messaging app is easily disputed by vendors. When captured through the Arihant AI mobile application, the image becomes an unalterable forensic record bound to the ERP transaction.
Traditional Paper QC vs. Arihant AI Mobile Traceability
Evaluating the procedural differences between disconnected receiving practices and integrated mobile ERP quality control.
| Inspection Dimension | Traditional Paper & Disconnected QC | Arihant AI Mobile Quality & Odoo |
|---|---|---|
| 1. Data Capture | Handwritten on paper inspection slips at the dock; prone to illegible handwriting and dirt smudges. | Guided touch interface with pre-validated dropdowns, numerical limits, and barcode scans. |
| 2. Photographic Evidence | Captured on private personal smartphones; scattered across WhatsApp groups with no batch metadata. | In-app camera locks photos directly to `quality.check` record with EXIF timestamp and GPS coordinates. |
| 3. Sampling Integrity | Inspectors check arbitrary sample sizes based on subjective intuition; inconsistent sample counts. | Automatic ISO 2859-1 AQL calculator mandates exact sample quantities before decision submission. |
| 4. ERP Synchronization | Manual re-entry by data clerks hours or days later; delays inventory availability and generates entry typos. | Instant REST API synchronization pushes decisions to Odoo `stock.picking` immediately from the dock. |
| 5. Rejection Communication | Suppliers notified days later by email; lack of timely proof leads to protracted commercial disputes. | Automated rejection dossier with high-res photo attachments dispatched to vendor within minutes. |
| 6. Debit Note Recovery | Manual calculation by finance days after billing; high risk of missed debits and commercial leakages. | System can trigger draft debit note in Odoo Invoicing matched against purchase order pricing. |
| 7. Vendor Accountability | Subjective opinions during negotiation meetings; purchasing teams lack empirical supplier defect history. | Continuous audited scorecard tracking on-time delivery, rejection percentages, and defect recurrence. |
When Quality Fails, the Workflow Shouldn't Stop at "REJECT"
Rejecting material on paper is easy; recovering commercial losses and preventing recurring line downtime is where factories struggle. Our system coordinates the entire post-rejection sequence across departments.
Defect Detected
Inspector logs 6 defects exceeding AQL threshold; marks status REJECT.
Physical Quarantine
App triggers mobile printer for red quarantine barcode tags; material locked in WH/Quarantine.
Evidence Attached
6 macro photos, dimensional deviations, and inspector sign-off bound to Odoo check.
ERP Stock Lock
Odoo prevents stock moves into production; inventory valuation held in suspense.
Purchase Alerted
Purchasing manager receives automated alert with defect summary and rejected quantity.
Vendor Notified
Official rejection letter with photo dossier automatically transmitted to vendor QA team.
Debit Note Prepared
Can trigger draft vendor debit note in Odoo Invoicing based on PO contract rates.
Scorecard Recalculated
Vendor's cumulative acceptance rate drops; flags CAPA requirement for repeated flaws.
One Inspection. Different Answers for Every Team.
A single incoming lot inspection at the receiving bay answers critical operational and financial questions across all manufacturing leadership roles.
Defect Standardization
- Did the lot satisfy ISO 2859-1 sample criteria?
- Are defect photos high-res and tamper-stamped?
- Is this an isolated vendor flaw or a recurring trend?
- Has a formal CAPA request been issued?
Supplier Accountability
- Which suppliers maintain a 98%+ pass rate?
- What is the total value of rejected stock this month?
- Has the vendor acknowledged the rejection evidence?
- Should next order require Level III tight inspection?
Line Feeding Continuity
- How much raw material is currently held in quarantine?
- Will this rejection cause an assembly line halt?
- Where are receiving bay inspection bottlenecks?
- Which suppliers pose critical production risks?
Commercial Recovery
- What is the exact financial debit pending recovery?
- Are debit notes systematically reconciled against bills?
- What is the monthly scrap recovery realization?
- Is working capital locked in uninspected inventory?

Forensic Quality Evidence Timeline (Sub-Second Audit Trail)
Every action taken on the mobile app is recorded with sub-second timestamps, actor identities, and network IP tags, eliminating any ambiguity about when and where defects were found.
Factory Floor Exception Protocols: When Things Go Wrong
Enterprise software must handle the chaotic realities of receiving bays. Here is how the system enforces compliance when inspectors encounter operational edge cases.
Incomplete Sample Count
Impact: Inspector attempts to submit pass decision after checking only 80 of 200 required samples.
Missing Defect Photo
Impact: Inspector flags a lot as rejected without attaching photographic proof.
Barcode Challan Mismatch
Impact: Physical challan QR code references a closed PO or mismatched vendor.
Duplicate Lot Inspection
Impact: Second inspector inadvertently attempts to inspect an already checked lot.
Dock Network Blackout
Impact: Wi-Fi and 5G cellular coverage fails in metal-clad receiving shed.
Overdue Vendor CAPA
Impact: Vendor dispatches new shipment while previous corrective action is overdue.
Edge Resilience: Inspection Continuity Without Network
Factory receiving docks are frequently located in deep basement bays or sheet-metal sheds with erratic Wi-Fi. The Arihant AI Flutter mobile client operates completely decoupled from network availability.
Real-Time Direct Sync
Inspections, measurements, and photos stream directly into Odoo 19 REST APIs via HTTPS/JSON-RPC.
Local SQLite Edge Cache
App seamlessly switches to local on-device SQLite database. AQL calculations and photo captures proceed uninterrupted.
Background Reconciliation
Background synchronization worker batch-uploads queued inspection payloads with transactional consistency checks.
Measurable Operational Impact: Real Outcomes

Dock Clerical Overhead
Eliminates the need for data entry clerks to manually transcribe handwritten paper inspection sheets into Odoo ERP.
Photo Evidence Defense
Every disputed rejection is backed by unalterable timestamped macro photographs, shutting down supplier denial arguments.
Standardized Sampling
Replaces inspector guesswork with mathematical AQL sampling plans configured to your plant's approved quality SOPs.
Instant Quarantine Lock
Rejected lots are immediately quarantined in Odoo, preventing unauthorized warehouse workers from moving defective stock into production.
Audited Scorecard Generation
Continuous performance tracking across suppliers provides objective data for quarterly vendor reviews and volume allocations.
Operating Context: High-Volume Industrial Receiving Bays
Understanding the throughput demands of heavy manufacturing and engineering facilities across Western India.
Managing 320+ Daily Incoming Raw Material Batches
