Built for the work you do
Sound familiar?
Most jobs still run on phones, chats and paper.
We know, because ours did too. Sitestack puts each of these in one place on the job.
Photos on six phones
Every photo goes on the job, with the date, time and where it was taken.
Progress in a WhatsApp group nobody can search
The site diary and daily report keep the day in one place, signed off and locked.
A snag list in someone's notes app
Each snag has a trade, a due date, photos and one clear next step.
The app

How we compare
Prices you can read before you talk to anyone.
A lot of construction software asks you to book a call to find out the price. Ours is on the page, and your subcontractors, consultants and clients never cost a seat.
| Product | What it costs a firm with 10 staff | Where the figure comes from |
|---|---|---|
| Sitestack | £1,910 a year, ex VAT£191 a month, paying yearly for ten months. Growth plan, Site Control and Safety Pro, free logins for everyone outside your staff. | Our pricing page |
| Procore | About $15,000 to $30,000 a year for a small general contractor (outside estimate), plus set up | Outside estimate; they do not publish a price |
| Zutec | G-Cloud range of £1,000 to £20,000 a unit a month; no scope given | Outside estimate; they do not publish a price |
| CompanyCam | Scale plan at $199 a month for 3 users plus $29 for each extra user. Ten users: about $402 a month, about $4,824 a year | Their published price list |
| Access Fonn | Not published. Listing sites quote £5,500 to £11,000 a year, but they conflict and are unverified | On request; they do not publish a price |
| Fieldwire | Business Plus at $89 per user a month. Ten users: $890 a month, $10,680 a year (annual billing) | Their published price list |
Checked 24 October 2026. Figures are in each company's own currency, not converted, and are not like for like: what each plan includes differs. Outside estimates are not quotes. Check current prices before you decide.
Who builds it
Built by a building company.
Photos scattered across phones. Progress updates buried in a WhatsApp group nobody can search. A snag list that is really someone's notes app. We run JLS Building and Property Development, a family run construction company, and Sitestack is the tool we built to fix this for ourselves. Now we are opening it up to other firms.
Read our story“We built Sitestack because our own jobs ran on WhatsApp and photos on six phones. It is the tool we want on site every day.”
