NEW FEATURE
Never get caught out by a revised drawing again
Overlay compares your old and new plans side by side and automatically highlights every change, so you’ll never price off the wrong set of drawings. Built right into Count-UP.
The Problem
Spotting drawing changes by eye is a costly gamble
A client sends through a revised set of plans halfway through your tender. Somewhere in those pages, something has changed, but good luck finding it by eye. Miss a single revision and you’re pricing off the wrong drawings, and that mistake comes straight out of your margin.
Overlay takes that risk off the table entirely.
Manually flicking between sheets
Squinting to spot the difference
Second-guessing what changed
Pricing off the wrong revision
How It Works
Track changes, but for your drawings
Upload both versions
Upload the old and new versions of the same drawing into Count-UP — takes seconds.
Overlay compares them
Overlay places them on top of each other and automatically highlights every difference in distinct colours.
Every change jumps out
No more flicking between sheets, no more squinting, no more second-guessing. Every revision is flagged at a glance.
Works across every drawing type you deal with:
Power plans
Lighting plans
Site plans
Schematics
Think of it like track changes for your plans: every update is flagged, so nothing slips through and you’re never caught out by a revision you didn’t see.
Who It’s For
Built for the jobs where a missed revision hurts most
If you’ve ever received updated drawings mid-tender and had to manually comb through every page to work out what changed, Overlay is for you. It earns its keep especially on larger commercial jobs, where the drawing sets are complex and the revisions keep coming.
Large commercial jobs
Complex drawing sets with multiple revisions throughout the tender.
Mid-tender revisions
When the client sends new plans and you need to know exactly what changed — fast.
High-margin tenders
When a single missed revision can blow your margin and cost you the job.
Pricing
Overlay is included on Plus and Premium
Overlay is part of Count-UP and comes built into the Plus plans and EE Premium. For just $50 more per year than the standard Yearly plan, it’s an easy yes.
