Comparison
CostKit vs Buildxact: which one fits your work?
Both are construction estimating tools but they're built for different jobs. Here's an honest side-by-side — pricing, what each does well, where each falls short, and the contractor profile each one is actually for.
Buildxact has carved out a strong niche with custom home builders and remodelers. It bundles three things — takeoff from PDF plans, estimate generation against a cost catalog, and lightweight job management (schedule, invoices, change orders) — into a single subscription. It originated in Australia and has built its US presence steadily over the past five years.
CostKit is faster and cheaper for the estimating part. Buildxact is more comprehensive across the lifecycle of a job. The right choice depends on whether you want best-in-class estimating speed or an all-in-one workflow that includes scheduling and invoicing.

Feature-by-feature
When to choose Buildxact
- You're a custom home builder or major remodeler who builds 5–25 homes a year and wants estimating + scheduling + invoicing in one tool.
- You receive PDF plans for most jobs and want digital takeoff in the same tool as your estimating workflow.
- You have time to build out a cost catalog with your local supplier pricing and want that catalog to stay current across estimates.
- You're moving off spreadsheets + QuickBooks and want to consolidate to a single construction-specific platform.
When to choose CostKit
- You're a trade contractor (HVAC, plumbing, electrical, roofing, painting) bidding 5–30 jobs a month — estimating speed is the constraint, not job management.
- You don't typically get blueprints — homeowners describe the project and you need to quote it fast.
- You don't want to spend 1–2 weeks building a cost catalog before you can produce your first estimate.
- You already have job management (Jobber, ServiceTitan, FieldEdge, etc.) and just need the estimating piece to be faster.
- You want to spend $39–$89/mo instead of $169–$269/mo for the part of the workflow that's actually a bottleneck.
Buildxact pros and cons
Pros
- Genuinely good all-in-one for custom builders
- Strong takeoff capability built-in
- Job scheduling and change order tracking
- Active development with new features regularly
- Solid customer support
Cons
- Long ramp time — building the cost catalog takes 1–2 weeks
- Overkill for trade contractors who just need estimates
- Higher monthly cost than estimating-only tools
- Catalog requires ongoing maintenance as supplier prices change
- Job management features are lighter than dedicated tools (Jobber, ServiceTitan)
Verdict
Buildxact is the right pick if you're a custom builder or remodeler who wants a single platform across estimating, takeoff, scheduling, and invoicing. CostKit is the right pick if estimating speed is your bottleneck — trade contractors who quote a lot of jobs from short descriptions or phone calls. Many CostKit users pair it with a separate job management tool (Jobber, ServiceTitan) that does scheduling/invoicing better than Buildxact's lighter built-in version. Different design centers, both valid for different shops.
