Manage leads, customers, service jobs, AMC contracts, billing, inventory, staff and WhatsApp communication — all from one connected system built for Indian service businesses.
Lead recorded, assigned and followed up
Estimate built from your product and service catalogue
Technician assigned, material issued, work closed
Billed from the job, with the items already on it
Dues tracked, contract renewal scheduled
Nothing is re-entered between stages — each step writes to the same record.
Separate tools each hold one piece of the business. The gaps between them are where follow-ups slip, material disappears and renewals go quiet.
Six areas of the business, one database underneath. A purchase updates stock. A closed job becomes an invoice. An invoice reaches the customer on WhatsApp.
GST invoices, estimates, payments, dues, expenses and vendor balances in one ledger.
Leads, follow-ups, customer history, sales visits and quotations on one timeline.
Live stock, average cost, low-stock alerts, serial numbers and warranty tracking.
Complaints, technician assignment, scheduled visits and contract renewals.
Shift attendance, leave, payroll and role-based permissions for every user.
Official Cloud API messages triggered by real events in your business data.
Grouped the way a service business actually thinks about its work — not as a list of disconnected features.
Every stage stays connected, so your team spends less time moving data between systems and more time serving customers.
Annual maintenance contracts are the steadiest income a service business has, and the easiest to lose quietly. ServiceKhata360 keeps contracts, renewal dates, service visits, complaints, technicians, invoices and payments on the same record — so a contract cannot expire without anyone noticing.
Coverage terms, start and end dates recorded
Scheduled service appears on the calendar
Work allocated to the right person for the job
Visit closed and added to the service history
Reminder fires before the contract lapses
Renewal message goes out on WhatsApp
Vendor bill recorded with items and tax
Quantities and average cost recalculated
Items issued against a job or invoice
Tax invoice raised from the same items
Receipt recorded against the invoice
Dues and advances updated automatically
When purchases, sales, returns and invoices happen, inventory and financial records stay connected. Record a purchase bill and stock rises with its average cost recalculated. Bill a job and the consumed items leave stock and land on the customer’s balance. No second spreadsheet to reconcile at month end.
ServiceKhata360 automates customer communication through the official WhatsApp Cloud API. Set the event, write the template with dynamic variables, and the message goes out on its own — with the chat history kept on the customer record.
The bill reaches the customer the moment you save it.
The customer is told the job is closed, automatically.
A renewal reminder lands before the contract lapses.
Attendance, leave, payroll, work assignment and role-based permissions run on the same system as the jobs themselves — so what a person did and what they are paid for come from one record.
Raise estimates and invoices, record payments, track dues and stock.
See assigned jobs, log visits, close complaints and record material used.
Duty logs and kilometre readings tied to the jobs the vehicle served.
Live reports on sales, dues, service load, attendance and renewals.
If your work involves a site visit, a technician and a bill afterwards, the workflow already fits.
Track seasonal service load, AMC visits and spare part usage per customer.
Manage recurring filter changes, AMC renewals and consumable stock.
Track installations, materials, complaints and AMC contracts from one system.
Run site projects with material dispatch, returns and staged invoicing.
Quote, dispatch material to site, reconcile returns and bill the job.
Log support complaints, assign engineers and track IT AMC contracts.
Keep serial numbers, warranty status and repair history per customer.
Coordinate staff attendance, scheduled visits and multi-site contracts.
Turn every call into a tracked job with material, labour and a GST bill.
Sales, service, stock, billing and staff share a single database instead of five tools.
Designed around site visits, technicians and contracts, not adapted from a generic CRM.
A finished job carries its own items into the GST invoice with nothing retyped.
Contracts, visits and renewal reminders built in rather than bolted on.
Purchases, dispatch, returns and invoices all move the same stock figures.
A desktop application for high-volume billing and a cloud app for everyone else.
