Your phone repair business thrives on speed and volume, but sloppy accounting can quietly kill your margins. Without clear visibility into parts costs, labor rates, and overhead, you'll never know which repairs are actually profitable—or which are draining cash. This guide shows you exactly how to track revenue and expenses so you can scale confidently.
Why Phone Repair Accounting Matters More Than You Think
Phone repair operates on thin margins. A screen replacement might generate $80 in revenue, but if your parts cost $35, labor burden is $20, and rent allocation is $10, you're left with $15 profit—or 19%. Miss one variable in your accounting, and you've mispriced half your jobs.
Tight tracking also reveals patterns: maybe battery replacements are 40% of your volume but only 12% of profit, signaling a need to bundle or upsell. Or you discover a supplier's parts fail more often, triggering warranty claims that eat into margins invisibly.
Revenue Tracking for Phone Repair
Set up separate line items for each service type. Screen repairs, battery replacements, liquid damage diagnosis, camera module swaps, and charging port fixes should be tracked separately in your accounting system. This tells you what's selling and what's actually making money.
Track parts revenue separately from labor. If you sell replacement batteries, chargers, or protective accessories directly to customers, categorize those sales distinctly. Many repair shops find retail sales have different margins than service labor—and sometimes higher profitability per hour.
Use a POS or service software that captures job details. Square, Lightspeed, or specialized repair software like Repairshopr or iFixScreens let you log:
- Device model and problem
- Parts used (with costs)
- Labor hours
- Customer contact info
- Completion date
This data is gold for spotting trends and justifying pricing adjustments.
Tracking Expenses with Precision
Inventory costing is non-negotiable. Phone parts inventory moves fast, and pricing varies by supplier. Use a cost method (FIFO, weighted average, or specific ID) and stick with it. If you buy screens from two vendors—one at $18 and one at $22—your accounting needs clarity on which batch you're pulling from on each job.
Categorize parts costs separately from labor burden. Your general ledger should show:
- Cost of parts sold (direct material)
- Technician wages (direct labor)
- Rent, utilities, insurance (overhead)
- Tools, equipment depreciation
- Supplier shipping and restocking fees
Don't ignore supplier-specific costs. Some parts distributors charge restocking fees (2–5%), have minimum orders, or build in rush-order premiums. Others offer bulk discounts at $500+ thresholds. Track these separately so you know the true landed cost of inventory.
Pricing Your Services Right
Once you have solid expense data, pricing becomes straightforward:
- Screen repair: If parts average $22, labor burden is $25/hour, and a job takes 45 minutes, your cost is roughly $41. Margin target of 40–50% suggests a price of $65–$82.
- Battery swap: Parts at $8, 30 minutes of labor (~$12 labor cost), $20 price point gets thin. Consider bundling with a diagnostics fee or raising to $35–$45.
- Liquid damage diagnosis: This is pure labor. Charge $25–$50 depending on market and depth of assessment.
Tools to Simplify Tracking
Use accounting software that integrates with your repair workflow:
- QuickBooks Online ($15–$55/month): General-purpose but customizable for service businesses
- Wave (free): Solid invoicing and expense tracking for smaller shops
- Repairshopr ($35–$99/month): Built for device repair with parts inventory, work orders, and basic P&L reporting
- Toast POS ($55+/month): Restaurant-grade but works for high-volume service businesses
Listing your repair services on Mercoly helps you get found by local customers, win leads, and showcase parts or services you sell—all while building a sales channel with built-in visibility.
Frequently Asked Questions
Q: How often should I reconcile my parts inventory with accounting records? Monthly is standard for retail; weekly if you're doing 15+ repairs daily and margins are tight.
Q: Should I price labor the same for all repair types? Not necessarily—complex jobs (water damage, motherboard diagnostics) justify higher hourly rates, while high-volume work (screen swaps) can run lower.
Q: What's a healthy profit margin for phone repair? Aim for 40–50% gross margin on parts-and-labor jobs after accounting for all direct costs; net profit (after overhead) typically runs 15–25% for established shops.
