Custom Quoting, Estimating & Proposal Software
Custom quoting and estimating software turns the pricing knowledge in your best estimator’s head — and in a fragile spreadsheet — into a tool anyone on your team can use to produce accurate, consistent quotes. Appex Technology builds it around your real pricing rules, materials, labor rates, and options, then connects won quotes to invoicing and delivery so the job does not get re-typed.
Sound familiar?
- Quotes are built in a spreadsheet only one or two people trust
- Two estimators price the same job differently
- Producing a quote takes hours of looking up rates and materials
- Margin is discovered after the job, not during quoting
- Won quotes are re-entered by hand into scheduling or invoicing
Core modules
Pricing rules engine
Your formulas, tiers, minimums, and markups encoded once and applied consistently.
Materials and labor catalog
Current costs and rates in one place, updated without editing formulas.
Options and configurations
Guided choices that prevent impossible combinations and price add-ons correctly.
Branded proposals
Professional PDF or web proposals with your terms, accepted online.
Margin visibility
Cost, price, and margin shown while quoting, with approval rules for discounts.
Quote-to-job handoff
Accepted quotes flow into scheduling, invoicing, or your CRM automatically.
Every build is scoped to your process — these are starting points, not a fixed package.
Custom vs off-the-shelf quoting & estimating
Quoting tools such as PandaDoc, Proposify, and QuoteWerks, the CPQ modules in Salesforce and HubSpot, or trade-specific estimating software.
Off-the-shelf is enough when…
A packaged tool works when pricing is a simple list with discounts and the main need is a nicer-looking proposal document.
Build custom when…
Build custom when your pricing logic is genuinely complex — dimensions, materials, labor, conditional options — when consistency and margin control matter, or when quotes need to drive the rest of your operation.
