Carsu Technologies

Carsu is workshop management software built for independent automotive workshops across Europe — tyre shops, general repair garages, and motorcycle workshops. It replaces the fragmented mix of paper scheduling, personal WhatsApp messages, disconnected supplier websites, and manual invoicing that most independent workshops still rely on. The platform combines scheduling, customer management (CRM), a visual workboard, estimates and invoicing, vehicle history tracking, and professional customer communication into a single system. Workshop owners and service advisors manage their entire daily operation from one dashboard, accessible on desktop and mobile. Carsu's core differentiator is native WhatsApp Business and Viber Business integration. Instead of using personal messaging apps to communicate with customers — losing message history when staff change, mixing personal and business conversations, and lacking any audit trail — workshops using Carsu send appointment confirmations, service updates, and follow-up messages through professional, traceable business channels directly from the platform. No third-party add-ons or middleware required. The platform is designed for the European independent aftermarket specifically. It supports multiple languages natively (English, Italian, Spanish, Greek, Dutch, and German) with localised interfaces, not just translated text. Workshop terminology, invoicing formats, and communication norms differ significantly across European markets — Carsu accounts for these differences rather than treating Europe as a single market. Key capabilities: Scheduling and appointment management — Online booking, calendar management, and automated reminders to reduce no-shows Customer management (CRM) — Full customer and vehicle history, searchable records, and segmentation for targeted communication Workboard — Visual job tracking across bays and technicians, real-time status updates Estimates and invoicing — Job templates, estimate generation, and invoice creation with local compliance WhatsApp Business and Viber Business — Professional customer messaging integrated directly into the workflow, not bolted on as a separate tool Campaign messaging — Seasonal promotions, service reminders, and re-engagement messages sent through business channels Reporting — Workshop performance metrics, revenue tracking, and operational insights Carsu is a cloud-based SaaS platform with tiered monthly pricing. It requires no hardware installation and works on any device with a browser. Free trial available. The platform is developed by Carsu Technologies, a European software company with deep roots in the automotive aftermarket industry.

How it works

Cast-A-Booking

Cast-A-Booking is a 24/7 AI booking assistant for appointment-based businesses: barbershops, hair and nail salons, spas and massage therapists, pet groomers, tattoo studios, cleaning and lawn services, personal trainers and mobile auto detailers. Clients book without an app. They open the business's link or scan its QR code and chat with an assistant that answers in English or Spanish, whichever the client writes in. The assistant answers the questions a front desk gets all day (hours, prices, services), checks real availability, lets the client pick their preferred team member or takes the next available, and books the appointment. Two services on the same day are booked as one visit with one start time, one confirmation and one payment. Every confirmation carries a link to reschedule or cancel within the notice window the business sets. Payments go straight to the business. Owners can ask for a deposit, a percentage or the full price at booking; the money lands in the business's own Stripe account and Cast-A-Booking takes no platform fee on any plan. The business's cancellation policy is shown on the payment page and recorded with each charge. Owners run everything from a dashboard: a calendar for every team member by day, week or month; services, prices and hours they edit themselves with changes live instantly; client records; revenue insights; day-before reminders for clients who opt in and an evening summary of tomorrow's appointments; a one-tap generator for Instagram and Google Business posts; and a print pack with the booking QR code for windows, counters and business cards. Businesses that travel to the client list the cities or ZIP codes they serve. The assistant checks the client's area before offering times, collects the street address, keeps drive time between visits and can add a trip charge to the price. Setup is self-serve and takes minutes. Plans start at $29 a month with no per-employee fees; Basic covers a team of two, Standard ten, Premium twenty-five, and Premium runs several locations from one account.
