Buildxact vs SiteCal for construction scheduling

1. The short answer

If you want one place to take off plans, build estimates, send quotes, raise purchase orders and cost your jobs — and schedule the work too — Buildxact does all of that, and it does it well.

If your estimating is already sorted and what you want is the program itself done properly — linked tasks, a locked baseline, trade colours, and a live link every trade can open — SiteCal does that for a fraction of the cost, without a whole estimating suite to learn. It's a focused construction program tool, not an all-in-one platform.

2. What each tool is built for

Buildxact is estimating-led, all-in-one software for residential builders and trades. The workflow runs end to end: take off the plans, build the estimate, send the quote, raise purchase orders, track job costs, schedule the work and invoice. The schedule is generated from your estimate and lives alongside everything else, on the Pro plan and up. Born in Melbourne, it's used across Australia, New Zealand, the UK and North America, and it's consistently ranked the country's #1 estimating platform.

SiteCal is built by a Melbourne site manager to do one job: the construction program. You get a working-day timeline and a month calendar of the same program, links that shift the whole chain when a task moves, a locked baseline with ahead/behind tracking, trade colour-coding, and a read-only link you can share with every trade and client. It doesn't estimate, cost or invoice — that's deliberate.

Buildxact runs the whole job, estimate to invoice. SiteCal runs the program — and shares it with everyone who has to turn up.

3. Feature comparison

Where each tool is strong. Ticks mean the feature is there and does the job well; half marks mean it's there but more basic, or works differently.

Buildxact's scheduling is a Gantt generated from your estimate; the "program" rows compare it against SiteCal's purpose-built scheduling. Buildxact keeps adding features — check their site for the latest.

4. What it actually costs

These are different products, so this isn't quite like for like — but if scheduling is what you're after, the gap is big. SiteCal includes it on every plan from $89/mo. In Buildxact, scheduling starts on the $399/mo Pro plan, because it comes bundled with estimating, takeoffs and job costing.

All prices in AUD. SiteCal is GST-inclusive. Buildxact lists its prices excluding GST; we've added 10% to compare like for like. Buildxact offers unlimited users on every plan and 15% off annual plans; scheduling is on the Pro plan and up. Prices checked October 2026.

5. Getting the program to your trades

A program only works if the people doing the work can see it. Both tools are cloud-based, so this isn't about emailing PDFs — it's about how a trade actually gets eyes on this week's plan.

Buildxact allows unlimited users, so you can add trades — but that means giving each one a login to your estimating and job-costing system, which is more than a subbie needs (and more of your numbers than you might want them seeing). SiteCal takes the opposite approach: you share a read-only link to just the program. No login, no account, no access to anything else.

6. Setup and learning curve

Buildxact does a lot, and there's more to set up because of it — price lists, templates, estimate recipes and job settings all pay off once they're in place, but they take time, and most teams lean on Buildxact's training and support to get there. That's a fair trade for software running your whole job.

SiteCal is designed to be learned in an afternoon. Add your stages and tasks, link them, colour them by trade, and share the link. There's less to configure, because it only does the program.

7. Where Buildxact is the better choice

SiteCal doesn't try to do what Buildxact does. Buildxact is the better fit if:

• You want estimating and quoting in one place. Takeoffs, supplier pricing and quotes are Buildxact's core, and SiteCal doesn't do them at all.
• You need job costing and purchase orders. Tracking budget against actual spend, raising POs and syncing to Xero or MYOB are built in.
• You want one system for the whole job. Estimate, schedule, cost and invoice in the same place, rather than a focused tool for each.
• Unlimited users matter. Every Buildxact plan includes unlimited users at no extra cost.

8. The verdict

They're not really rivals so much as different shapes. If you want the whole commercial workflow, Buildxact is a strong, Australian-made choice. If what you want is the program — built fast, kept true, and shared with every trade — that's the job SiteCal was built for. Plenty of builders use one for the money and the other for the program.
