In every plan
Raise, fix and verify every snag
Raise a snag on your phone, assign it to a company, and see it through to a checked and closed record. When work is complete, a separate defects register keeps what comes back after.
Best for: Contractors, housebuilders and fit out teams who chase snags through photos, spreadsheets and messages today. In every plan, nothing extra to pay.
Snags from raised to closed
Raise it where you stand
Give it a title, a priority, a location and a trade, and attach photos. Each snag gets its own reference, such as SN-0004.
Assign it to a company
Assign a snag to a company or a person, with a due date from your own priority targets in working days. If you set no target, no date is invented.
Fix, then inspect
The assignee starts it and marks it ready for inspection. Whoever verifies snags then closes it or rejects it with a reason. A closed snag can be reopened.
Comments and history
Everyone who can see a snag can comment on it. Each step is recorded with who took it and when.
Photos on every snag
Before and after
Attach photos as before or after. The proof the fix was done sits on the snag, not in someone's camera roll.
Subcontractors see what is theirs
A subcontractor with a free login sees the snags assigned to them, and can start them and mark them ready.
Lists you can hand over
Download the snag register as a PDF, including a version grouped by area. Filter first, so you send only what the reader needs.
Clients, consultants and defects
Client access where you allow it
Clients and consultants can be allowed to view, raise and verify snags. You decide per person, so a client can inspect and close what matters to them.
A defects register after completion
Defects reported after completion have their own register, with who reported each one, the contract notice and a correction date from the period you set.
Move a snag to defects
When a snag is still open at completion, your team can move it to the defects register. The defect is written from the snag in one step, so nothing is retyped.

Plain words
What it does and does not do
What it does not do. Sitestack records who raised, fixed and checked each item, and when. It does not decide what counts as a defect under your contract, and it does not give legal advice on notices or defects periods. Check your own contract.
