FlatRateKit
What Is FlatRateKit?
Overview
FlatRateKit is a free, browser-based HVAC pricing toolkit for owner-operators and small residential service shops. It helps contractors build or audit a flat-rate service menu using their own labor, parts, overhead, utilization, and target-margin assumptions. The product is deliberately lighter than a field-service management platform: there is no CRM, dispatch board, invoicing module, or sales process to complete before using the tools.
Key Features
The HVAC labor-rate calculator helps a shop estimate a sustainable billable rate from wages, payroll burden, overhead, available work hours, and realistic billable utilization. The flat-rate pricing calculator then combines labor, parts, overhead, and margin assumptions into a clear service price while showing the math behind the result. A separate profit-margin calculator helps users distinguish markup from gross margin and test the effect of changing a price or cost input.
FlatRateKit also provides downloadable CSV and spreadsheet-ready HVAC price-book templates. These templates organize service tasks, descriptions, labor allowances, parts, and prices in a format that a contractor can edit and adapt. Supporting guides explain overhead recovery, billable-hour utilization, markup versus margin, and the risks of copying another company's price book without accounting for different operating costs.
Use Cases
A small HVAC contractor can use FlatRateKit when moving from time-and-material billing to flat-rate pricing, reviewing an outdated service menu, or preparing cleaner price-book data before adopting larger field-service software. A shop can begin with a few common repairs, compare the calculated prices with its current menu, and identify which assumptions are causing a gap. The tools are also useful for checking whether labor is being recovered consistently and whether a quoted price reflects the intended gross margin.
Getting Started
Visit the FlatRateKit website and open the calculator that matches the current pricing question. Start with the labor-rate calculator if the shop does not have a reliable billable rate. Then test a representative service task in the flat-rate calculator using the shop's own labor time, parts, overhead, and margin assumptions. Review the displayed formula, adjust the inputs, and record the result in the downloadable price-book template. Repeat the process for additional services as needed.
Pricing and Access
FlatRateKit is free to use. Visitors can open the calculators, read the methodology, and download the templates without buying a subscription or booking a demo. The toolkit does not promise a universal correct price or guaranteed profitability; it gives contractors transparent calculations and reusable worksheets so they can make informed pricing decisions based on their own business. The primary audience is small North American residential HVAC service and repair shops that want a practical, understandable starting point for flat-rate pricing.
