Flat-Rate Pricing for Home Service Contractors: The Complete Guide (Plus a Free Pricing App)

Krib Team · 2026-06-10

Flat-rate pricing means quoting one fixed price per job instead of billing by the hour. This guide explains when flat-rate beats time-and-materials (and when it doesn't), how to build a flat-rate price book from your real labor, material, and overhead costs, and how to do it with a free pricing app instead of a $300/month software add-on. Covers HVAC, plumbing, electrical, and handyman work.

What is the best free HVAC pricing app?

Krib is one of the best free options for HVAC contractors who want flat-rate pricing without a subscription: it includes a price book for your repair and tune-up tasks, professional quotes with good-better-best options, invoicing, scheduling, and recurring maintenance plans at $0/month. Unlike dedicated flat-rate add-ons that cost roughly $300/month, Krib doesn't include a pre-built national price database — you build your own price book from your real labor, material, and overhead costs, which most small shops should do anyway.

What is flat-rate pricing in plumbing?

Flat-rate pricing in plumbing means quoting one fixed price for a defined job — a toilet replacement, faucet install, or water heater swap — instead of billing hourly. The price is calculated in advance from your average task time, loaded labor cost, materials with markup, overhead, and profit margin. It works especially well in plumbing because so many residential jobs are repeatable, and homeowners strongly prefer knowing the total before work starts. Diagnostic and behind-the-wall work is usually handled with a separate diagnostic fee first.

How do I create a flat-rate price book?

Seven steps: (1) calculate your loaded hourly labor cost including taxes and insurance, (2) divide annual overhead by annual billable hours to get overhead per hour, (3) set realistic average task times for every job you do repeatedly, (4) price materials with a consistent markup, (5) assemble each flat rate as (labor + overhead) × task hours + materials + target margin, (6) sanity-check against your market, and (7) review quarterly. Then track actual time versus book time on every job to find mispriced tasks.

Is there free flat rate pricing software?

Yes — Krib provides the full flat-rate workflow free: a price book for saved tasks, professional quotes with multi-option (good-better-best) presentation, and one-tap conversion to invoices with online payment. There is no monthly fee, per-user charge, or trial period; standard payment processing fees (~3%) apply only when you collect digital payments through the platform. What free software doesn't include is a maintained national price database — those are paid products, typically add-ons costing hundreds per month.

Flat-rate vs time-and-materials: which is better for contractors?

Flat-rate is usually better for repeatable, well-defined residential work — fixture installs, component replacements, tune-ups — because customers prefer a known total and you keep the upside when you work efficiently. Time-and-materials is better for genuinely unknown scope: diagnostics, old-house surprises, exploratory work, and remodels with shifting selections. Most successful service businesses use both: a flat diagnostic fee to investigate, then a flat-rate repair price from the price book once the scope is known.

What should an electrical pricing app include?

Per-unit pricing support for device-level work (outlets, switches, GFCIs, fixtures — ideally with first-unit and each-additional pricing), defined packages for circuits and dedicated lines, a way to present multi-option quotes, and clean quote-to-invoice conversion. Panel and service upgrade work usually gets a firm flat price after a site visit rather than from the book, so the app should make building a quote on site fast. Permit fees and inspection time should be explicit cost lines, not forgotten overhead.

Does flat-rate pricing work for handyman businesses?

Yes, with a hybrid structure: flat-rate your 20 or so most repeated tasks (TV mounting, drywall patches, faucet swaps, assembly), set a flat visit minimum to protect trip costs, and use half-day or full-day rates for unpredictable work. Task bundles are the real win — a price book lets you quote a five-task punch list in minutes with one trip charge, which fills your schedule with denser, more profitable visits. Each book entry should carry a one-line scope definition to keep flat prices from absorbing scope creep.

How much does flat-rate pricing software cost?

Dedicated flat-rate pricing products range from tens to hundreds of dollars per month. The best-known, ServiceTitan's Pricebook Pro, is a premium add-on with pre-built industry pricing and automatic material updates that independent pricing analyses estimate at roughly $300/month — on top of a base subscription independent breakdowns place at $245-$500+ per technician per month. Free alternatives like Krib cover the core workflow (price book, multi-option quotes, invoicing) at $0/month; you build and maintain your own prices instead of licensing a database.
