Every call that rings out is an enquiry that might book with the site down the road before you get a chance to call back. Put your own numbers in below and see the monthly and annual cost — the maths is shown in full, nothing hidden.
Out-of-hours, lunchtime, on-site with a customer — Sturdy Ai picks up under your brand and quotes real availability.
Full booking, not just a message-taker — Stora today, others on request. No card details over the phone; a secure checkout link is texted instead.
Agent hits an unfamiliar question → texts you → your reply gets written into its knowledge → it calls the customer back with the answer.
Self-updating on facts as it learns your business; workflow changes stay human-approved before they go live.
You get a leak map of exactly where enquiries and hours are going missing, on your own numbers — not a generic estimate like the one above. A paid £500 scoping session goes further — recommended past 500 units — credited in full against Build within 30 days.
This calculator is a model built on your inputs, not a measurement of your site — the missed-call and conversion percentages are examples to adjust, not researched averages. The £640–£1,800 lifetime-value range and the ~60–80 calls/month baseline are from Sturdy Ai's own self-storage unit economics.
