From Customer to Payment
Keep your complete service workflow organized:
Customer → Appointment → Job → Quote → Invoice → Payment → Profitability
Track every stage of your service operation without switching between multiple tools.
Customer Management
Keep customer information, contact details, service history, jobs, quotes, invoices, payments, and outstanding balances organized in one place.
Appointments
Schedule and manage upcoming appointments with customer, service, date, time, location, assigned employee, and appointment status.
Job Management
Track service jobs from creation to completion. Assign services, customers, employees, priorities, dates, estimated amounts, actual amounts, and job status.
Quotes
Create professional quotes with service line items, quantities, prices, discounts, taxes, expiry dates, and quote status.
- Draft
- Sent
- Accepted
- Rejected
- Expired
- Cancelled
Invoices & Payments
Create invoices, track due dates, record payments, and monitor outstanding customer balances.
The application keeps invoice revenue and payment collections separate to prevent the same transaction from being counted twice.
Expenses
Track materials, labor, transportation, equipment, advertising, utilities, insurance, software, office costs, and other business expenses.
Know Your Profit
Analyze your business performance using actual stored invoices and expenses.
Net Profit = Revenue − Expenses
Payments are treated as collections against invoices and are not added as a second revenue stream.
