A repair shop on the verge of bottlenecking
FixMania (Chaussée de Ninove 233, Molenbeek) repairs smartphones, sells refurbished devices and buys back appliances. The shop was thriving — but on paper tools. No online booking, hence the queues. No digital tracking, hence calls and clients coming back too early. No proper POS, hence handwritten tickets. The owner wanted a full stack: web, admin, POS, WhatsApp.
The pain points
we removed
Concretely, here is what made daily management infernal before we stepped in.
Counter queues
No online booking → everyone shows up at once, queues, frustration, walk-aways.
"Is my phone ready?"
10 calls a day from clients wanting status. The tech is constantly interrupted.
Clients coming back too early
Without notification, clients return when the repair isn't done. They queue, they get angry, they leave.
Quote scribbles
Quotes scribbled on paper, never signed, lost. No traceability, possible disputes.
Stock on Excel
Spare parts and refurbished items on Excel never up to date. Stockouts, duplicates, no valuation.
Buybacks by feel
No buyback grid, case-by-case negotiation. Inconsistent margins, clients feeling cheated.
No business WhatsApp
Personal number saturated, mix of clients/family, no message templates, lost leads.
No refurbished e-shop
Physical store only → invisible on Google, sales capped by opening hours.
Classic till
Handwritten or no tickets at all. Accounting rebuilt at month-end, blindly.
What we put
in place
A Web + Admin + POS trio, all connected to WhatsApp Business and the shop's bookkeeping.
Showcase site + leads
No digital presence, shop invisible on Google.
fixmania.be with services, lead form, practical info. Continuous appointment generation.
Public repair tracking
10 calls a day: "is my phone ready?"
`/api/suivi/[id]` URL sent to the client. Live status, no calls. The tech works in peace.
Repairs in Kanban
No structured tracking, the tech wrote in a notebook.
Kanban view in admin: received → diagnosis → in progress → awaiting part → ready → delivered.
Dedicated POS + ESC/POS printing
Handwritten tickets or none. Approximate accounting.
Dedicated POS app with pro ticket printing via WebUSB ESC/POS. Client ticket + clean accounting feed.
WhatsApp Business API (Meta Cloud)
Personal number saturated, no templates.
Official WhatsApp Business account, message templates, inbound webhook, conversation history in the admin.
24h auto follow-up cron
No post-repair follow-up, lost sales.
`/api/cron/followup` automatically sends a message 24h after the repair: Google review, satisfaction, upsell.
Structured Buyback module
Buyback by feel, inconsistent margins, disappointed clients.
Buyback grid by model/condition, instant quote, full traceability.
Connected inventory
Excel stock never up to date, frequent shortages.
Central inventory, threshold alerts, real-time valuation, link to supplier orders.
RBAC 6 roles
Everyone sees everything, no separation of duties.
super_admin, admin, manager, tech, support, staff. Each profile sees only their pages.
What truly changed for the owner
No more counter queues — clients have a digital channel to track their repair
No more clients returning for nothing — they get a notification when it's ready
The tech works in peace, no longer interrupted by "is it ready?" calls
The POS prints pro tickets and feeds accounting without re-entry
Pro WhatsApp Business with templates, history and webhook
The Buyback module has a clear grid — no more gut-feel negotiations
The owner runs the shop from a single tool instead of 5 notebooks
“It was chaos. Clients came back to the shop too early, it created queues, we no longer knew where each repair stood. Now the client gets a notification when it's ready, no one comes back for nothing, and every device is tracked step by step.”
No more queues — every repair tracked in real time
