Comparing three supplier quotes

Three quotes for the same driveway base course that can't be compared at a glance: different descriptions and units, GST shown different ways, delivery priced differently, and one arithmetic slip. This is the real QuantDoc engine running on them; nothing here is mocked up.

The requirement: 40 tonnes of 20mm crushed aggregate and 12 tonnes of washed bedding sand, delivered to site.

This example is deliberately unresolved: one cost is still unknown, so no supplier can honestly be called cheapest yet.

1. The source quotes (PDF)

Try a user assumption: bulk density

One supplier prices sand by the cubic metre. QuantDoc won't guess how many tonnes that is: it needs a density, which is your assumption. With it set, that line becomes comparable but is marked Estimated.

No density assumption Assume 1.6 t/m³

Unable to verify this comparison yet — here's what needs clarifying

Until these are answered, no supplier can be called the cheapest overall.

Coastal Landscape Supplies lists delivery but hasn't priced it yet.
These suppliers priced different quantities. We've lined their prices up to the same quantity using each supplier's own rate.
At least one quote has figures that don't add up. Check before you accept it.

What each quote covers

Each part of the job you need, and whether each supplier priced it. Missing parts are never counted as $0.

Side-by-side comparison

“Unknown” means the quote doesn't give a usable figure — it is never treated as $0. “Included” means the supplier says it's part of another price.
