From Paper Slips to ₹5 Cr+ in Sales on a Single Phone
How Metro Tech engineered a custom mobile shop ERP for JollyBaba Mobile to eliminate paper repair slips, track second-hand stock, and automate customer WhatsApp alerts across 5 branches.
The Operational Bottleneck
Running a bustling multi-branch mobile repair and resale shop meant balancing hundreds of walk-in customers, parts inventory, and cash credit. For years, operations relied on paper slips pinned to repaired phones, physical notebooks for stock, and an offline khata ledger.
This fragmentation caused daily bottlenecks: customers constantly called asking if their repairs were ready, technicians lacked visibility on urgent repair priorities, and owners spent hours manually reconciling cash and credit each evening.
The Metro Tech Solution
Rather than introducing complex desktop enterprise software that counter staff would resist, Metro Tech built a lightning-fast, keyboard-safe progressive web app tailored specifically for busy phone counters.
- Morning Triage Dashboard: A single screen showing urgent repair tickets due today, technician queues, and yesterday’s cash vs credit reconciliations.
- Automated WhatsApp Notifications: Integrated with the official WhatsApp Business Cloud API. When a technician marks a ticket "Ready", the customer immediately receives an automated WhatsApp update with the pickup amount.
- Serial-Tracked Inventory & Quick Cart: Instant IMEI lookup for second-hand phone trade-ins, parts stock alerts, and a bulk "Sell Selected" checkout.
- Role-Based Access: Branch owners view consolidated balance sheets and revenue, while technicians see only their assigned repair queue.
Real Production Impact
“The whole shop runs on my phone now. Tickets, stock, billing, all in a few taps. We eliminated phone calls asking if repairs were ready.”
