Short answer: A warranty and repair system does three things: online registration via a serial-number QR code, online repair requests, and automatic repair status alerts. Brands selling a few thousand units a year can usually launch in 7 weeks for about NT$150,000-400,000 and cut "where is my repair" calls by more than half.
A small appliance brand selling 7,000 units a year receives about 600 paper warranty cards a month, and an assistant types them into Excel. Its repair center has 80 units in progress, and support takes 30 calls a day, 40% asking "is it fixed yet." Without a receipt, warranty status comes from memory.
When It Fits and When It Doesn't
Bottom line: brands with serial numbers, repair volume and repeat-purchase potential benefit most; very small or no-repair brands don't need it.
| Good fit | Poor fit |
|---|---|
| Serialized products, 2,000+ units a year | Under 500 units a year, fewer than 5 repairs a month |
| Own repair center or authorized repair partners | Broken items are replaced, never repaired |
| Multi-channel sales (dealers, e-commerce, stores) needing one warranty record | Sold on one marketplace that already has full after-sales tools |
Alternatives Matrix
Bottom line: Google Forms solves registration only; status alerts and serial validation are what justify a custom build.
| Option | Pros | Cons | Cost |
|---|---|---|---|
| Google Forms + spreadsheet | Same-day, free | No serial validation, no alerts, duplicates | NT$0 |
| Foreign help-desk SaaS | Full ticketing and knowledge base | No Taiwan receipt or serial logic; per-seat fees | About NT$600-3,000 per seat per month |
| ERP after-sales module | Shares inventory and parts data | Weak consumer interface, costly customization | NT$300,000-1,000,000 |
| Custom warranty and repair system | QR registration, LINE alerts, serial checks built around your process | Needs 6-8 weeks and a maintenance budget | NT$150,000-400,000 |
Step-by-Step Process
Bottom line: 7 weeks in 5 phases; defining serial rules in week one matters most.
- Week 1 | Requirements and serial rules: serial formats, shipment data sources, warranty start rules (purchase or factory date). Deliverables: flowchart and field list (Notion).
- Week 2 | Interface design: mobile registration page, repair form, back-office repair board. Deliverable: Figma prototype.
- Weeks 3-5 | Development: Laravel back office and API, QR generation, serial import, receipt photo upload, repair status flow; status pushes via the LINE Messaging API, and ECPay for paid repairs. Deliverable: staging site.
- Week 6 | Testing and migration: import old Excel warranty data; technicians test 30 real tickets.
- Week 7 | Launch: QR labels on new products, revised in-box card; Cloudflare and UptimeRobot monitoring.
Real Cost Breakdown
Bottom line: beyond the build, reserve about NT$30,000-60,000 a year to run it.
- Build: basic (registration, repair requests, alerts) NT$150,000-250,000; with parts inventory, partner permissions and paid-repair payments NT$250,000-400,000.
- LINE messages: beyond your plan's free quota, billed per message; 600 tickets with 3 alerts each is about 1,800 messages a month, so pick the right plan.
- Payment fees: card payments for paid repairs from about 2.75%.
- Hosting and maintenance: about NT$1,000-3,000 a month for hosting, maintenance billed separately.
Reality vs Expectations
Bottom line: projects stall on dirty serial data, not technology.
- Expected: the factory has clean serials. Reality: 10-20% are often duplicated or missing.
- Expected: customers will scan and register. Reality: without an incentive, about 20% do; an extended warranty or consumable coupon lifts it clearly.
- Expected: technicians update status in real time. Reality: status must change with one scan of the ticket, or it will lag.
Common Traps and Fixes
Bottom line: all five can be prevented during planning.
- Guessable serials: add a random verification token to QR links to stop fake registrations.
- Warranty start disputes: state the rule on the registration page and require a receipt photo.
- Too many alerts, then blocked: notify only at 4 points: received, quoted, repaired, shipped.
- Undisclosed data collection: list purpose and retention on the page to meet Taiwan's Personal Data Protection Act notice duty.
- Dealer data out of sync: import shipped serials automatically every day.
Success Metrics and 90-Day Roadmap
Bottom line: watch registration rate, status calls and average repair days.
- Day 30: 25% registration on new shipments; status calls down 30%.
- Day 60: average repair days measured in the back office; slowest step identified.
- Day 90: 35%+ registration; first consumable or extended-warranty campaign to the list.
Decision Checklist
Bottom line: 6 or more checks means it is worth planning.
- ☐ Products have unique serial numbers
- ☐ More than 2,000 units sold a year
- ☐ More than 20 repairs a month
- ☐ Support is often asked about repair status
- ☐ Warranty data is split across cards, Excel and marketplaces
- ☐ You have dealers or repair partners
- ☐ You have had warranty disputes
- ☐ You want consumable or launch campaigns
- ☐ Shipment data can export serials
- ☐ You can budget NT$30,000+ a year to run it
FAQ
Do we need an app for warranty registration?
No. A mobile web page plus LINE is enough; customers scan the QR code and it opens without any download.
How do we handle customers without a receipt?
Estimate from the serial's shipment date plus a reasonable distribution period, and publish that rule on the registration page.
Can it connect to our ERP?
Yes. Typically shipped serials are imported daily and repair parts are written back; integration is priced by the ERP's interface.
