Serialized Inventory Management Software
Stop inventory shrinkage, eliminate warranty fraud, and track every expensive OLED screen, motherboard, and battery by its unique serial number or IMEI from supplier delivery to customer invoice.
What is Serialized Inventory Management?
Understanding the difference between SKU, Serial Number, IMEI, and Batch Lot is the foundation of high-profit repair operations.
SKU (Stock Keeping Unit)
Generic Model Identifier
Tells you that you have 40 iPhone 14 Pro replacement screens in stock. It cannot distinguish one screen from another or tell you which specific unit was installed in a customer’s phone.
Unique Serial Number
Single Physical Unit Identity
Assigns a unique identifier (e.g., SCR-8841-A9) to that single piece of glass. If a screen fails or is returned under warranty, the serial number proves exactly when it was bought and who installed it.
IMEI (Mobile Equipment ID)
15-Digit Cellular Identity
Unique to cellular phones, tablets, and smartwatches. Links customer devices directly to repair tickets, diagnostic logs, and warranty histories across all store branches.
Batch / Lot Number
Supplier Shipment Group
Groups parts received in the same vendor purchase order. If a specific batch of replacement batteries swells or degrades, you can instantly identify and recall every unit from that shipment.
The 5-Stage Serialized Lifecycle in TamamFlow
Never wonder where a part came from or where it went. Every serial number moves through an unbroken chain of custody.
1. Bulk Supplier Receiving
Scan manufacturer serial barcodes during purchase order stock-in. Automatically generate and print tamper-evident serialized QR labels for bulk un-barcoded parts.
2. Bin & Safe Location
Assign serialized parts to specific stockrooms, shelves, or secure safes. Real-time stock counts reflect exactly which serial numbers reside in each location.
3. Technician Toolbox Dispatch
When a technician grabs a $250 iPad screen for a job, they scan it. Custody transfers immediately from central stock to that technician’s personal bench ledger.
4. Ticket & Invoice Binding
Upon repair completion, the serial number is permanently locked to the customer ticket and printed on the official invoice for transparent warranty verification.
5. Warranty Claim Verification
If a customer returns 60 days later claiming a defective screen, simply scan it. The system verifies if that exact serial number was installed by your shop or a competitor.
How Serialized Tracking Saves Thousands in Fake Warranty Claims
Warranty fraud accounts for up to 8% of repair shop profit leakage. Here is how TamamFlow shields your bottom line.
The Classic Screen Swapping Scam
The Claim
A customer returns 3 weeks after an iPhone 15 Pro OLED screen replacement, holding a cracked, flickering screen and demanding a free warranty replacement under your 90-day guarantee.
The Traditional Loss
Without serial numbers, you have no way to prove whether this is the genuine OEM screen you installed or a cheap counterfeit they broke elsewhere and swapped. You eat the $220 loss.
The TamamFlow Shield
With TamamFlow, the technician scans the barcode on the flex cable. The system shows your shop installed Serial #OLED-7719; the returned screen is Serial #OLED-2104. Fraud averted in 3 seconds.
Multi-Branch Transfers & Technician Accountability
Inter-Branch Stock Transit
