A closer look
01
Try the count tool free, on this page
Upload a plan up to 25 MB into the interactive workspace and place count marks without signup. Files and marks stay in this browser tab and do not move into an account. Create a free account and upload the drawing there to save a new project with counts and a Bill of Quantities.
02
Count where the items appear
Place visible marks on the plan so another reviewer can understand what was counted and where — every total stays auditable back to the marks that produced it.
03
Counts stay grouped as the job evolves
Marks group by type — outlets, downlights, doors, fixtures — so 'GPO outlets: 46' is one living line, not 46 anonymous dots. Groups can be split when scope separates (power vs data on the same symbol) or merged when it doesn't, and a paused count can be resumed later without starting over. That lifecycle matters on real jobs, where the drawing changes between the first pass and the final number.
04
Totals land in the Bill of Quantities
Each count group feeds a line in the live Bill of Quantities, alongside the calibrated measurements, so counted quantities price the same way measured ones do — no tallying marks into a spreadsheet.
05
Export count evidence
Share marked-up drawings with count locations visible instead of only passing along a number in a spreadsheet.

Common questions
Questions about PDF count tool
Is there a free PDF count tool online?
Yes. Upload a drawing and place count marks in the interactive workspace without an account. Demo work stays in the browser tab. A free account saves new work on one project, including counts and a Bill of Quantities; exports and sharing require a paid plan or eligible card-required trial.
Can I count items on a PDF construction drawing?
Yes. ContractorCounter lets users place count marks on PDF drawings and keep those counts visible alongside the rest of the markup context.
How do I count outlets, fixtures, or doors on a plan?
Pick the count tool, choose or create a group for the item type, and click each symbol on the sheet. Every click drops a visible mark and increments that group's total, so 'downlights: 84' stays tied to 84 visible marks a reviewer can check. The AI agent can also take a first pass at placing counts, which you review before anything commits.
Can I get count totals out, not just marks on the drawing?
Yes — every count group is a line in the live Bill of Quantities with its running total, and the marked-up PDF export shows the marks in place. The BOQ is where totals become priced quote lines, so counts never need re-tallying into a spreadsheet.
What happens to counts when the drawing is revised?
Count groups have a lifecycle built for revisions: resume a group to keep counting on the new issue, split it if the scope divides, or merge groups that turn out to be the same item. The group's BOQ line updates as the total changes.
