AI Parts Inventory for Phone Repair

Know What You Have, What You Need, and Never Miss a Sale

Running out of a common screen is lost money. AI keeps that from happening.

Phone repair shops run on parts. Screens, batteries, cameras, charging ports — if you don't have the right part, you lose the job. If you over-order, money sits on a shelf. The sweet spot is knowing exactly what to stock and when to reorder.

This guide shows you how to set up a simple parts inventory system using AI and free tools.

Chapter 1: Setting Up Your Parts Inventory

Your inventory is only useful if it's accurate and up to date.

Build Your Inventory Spreadsheet

Tool to know: Google Sheets — a free spreadsheet in your browser.

Create columns for: Part Name, Device Compatibility, Part Number, Supplier, Quantity on Hand, Cost Per Part, Reorder Point.

Free tip: Ask ChatGPT: "Create a parts inventory spreadsheet template for a cell phone repair shop. Include columns for part name, compatible devices, part number, supplier, quantity in stock, unit cost, and minimum reorder level."

Start With Your Top 20 Parts

Don't try to track everything at once. Start with your 20 most-used parts. These are probably screens and batteries for the top 5 device models you see.

Chapter 2: Setting Reorder Points

A reorder point is the minimum stock level that triggers a new order.

How to Calculate Reorder Points

Consider:

• How many of this part do you use per week?
• How long does delivery take?

If you use 3 iPhone 14 screens per week and delivery takes 2 days, set your reorder point at 6.

Free tip: Ask ChatGPT: "Help me calculate reorder points for phone repair parts. I use [quantity] per week and delivery takes [days]. What reorder point should I set?"

Color Code Your Spreadsheet

In Google Sheets, use conditional formatting to highlight cells in red when stock hits the reorder point. You'll see exactly what needs ordering at a glance.

Chapter 3: Using AI to Predict What to Stock

Your repair history tells you what parts to keep. AI can analyze it for you.

Paste Your Repair History Into ChatGPT

What it does: AI finds patterns in your past jobs and tells you what to stock more of.

Free tip: Export your repair history from your job tracking sheet. Copy it into ChatGPT and say: "Here are my last 3 months of phone repair jobs. Which device models and repair types come up most often? What parts should I always have in stock?"

Watch for Trends

• New phone releases drive new part demand
• Older models phase out over time
• Seasonal drops (back to school = more cracked screens)

Free tip: Ask ChatGPT: "What are the most commonly needed phone repair parts in 2025 and which device models generate the most repair business?"

Chapter 4: Managing Multiple Suppliers

Most phone repair shops use 2-3 suppliers. Tracking them all in one place saves time and money.

Build a Supplier Comparison Sheet

In Google Sheets, create a sheet for each part you order from multiple suppliers. Track:

• Supplier name
• Price per unit
• Average delivery time
• Quality rating (from your experience)
• Minimum order quantity

Popular Phone Repair Part Suppliers

• iFixit (repair parts and tools)
• Mobile Sentrix
• MobileSentrix
• Injured Gadgets

Free tip: Ask ChatGPT: "What should I look for when comparing phone repair part suppliers? Give me a checklist of evaluation criteria."

Chapter 5: Tracking Parts Costs per Repair

Knowing your cost per repair is how you know if your pricing is actually profitable.

Simple Job Profitability Calculation

For every repair:

• Parts cost + labor time = total cost
• Price charged - total cost = profit

Free tip: Ask ChatGPT: "Help me build a simple profitability calculator for a phone repair shop. I want to input parts cost, time spent, and my hourly rate, and get back the profit margin."

Parts That Get Too Expensive to Repair

Sometimes the parts cost for an older device approaches the device's market value. Track this. If a Samsung Galaxy S8 screen costs $60 and the phone is worth $80, it may not make sense to stock that part.

Chapter 6: Dealing With Dead Stock

Dead stock is parts you ordered but never use. It ties up cash and clutters your storage.

Identify Dead Stock

In your inventory sheet, sort by "Last Used Date." Any part not used in 6+ months is dead stock.

Ways to Move Dead Stock

1. List on eBay or Swappa as spare parts
2. Offer a discount on repairs using those parts
3. Return to supplier if they accept returns
4. Trade with another local repair shop

Free tip: Ask ChatGPT: "I have leftover phone repair parts I'm not using. Write a short eBay listing for [part name] compatible with [device model]. Make it accurate and appealing to DIY repairers."
