Turning your historic Will archive into actionable client intelligence
Begin by setting the total number of Wills in your archive, then adjust the assumptions to match your practice: cost per Will, the share flagged as high or urgent risk, how many of those convert to a paid review, your typical fees, and any cross-sell from LPA or IHT planning work. The calculator updates instantly to show your investment, the revenue opportunity, the fee-earner time Willsure frees up, and your net return.

A solicitor's salary is a fixed cost - the firm pays it whether they digitise the archive or charge their time to clients. So the value of Willsure taking on this non-chargeable admin is not a cash saving but the chargeable revenue those freed hours can now generate. The internal cost rate (£250/hr) is shown for context only and is not added to the return.

Chargeable capacity @ £350/hr
30min manual archive admin per Will → 5min Willsure. Released from non-chargeable work, solicitors can charge that time to clients at £350/hr - not a cost saving, since their salary is paid regardless.
NET Benefit to Firm
£267,750
Cash return + chargeable capacity
£121,800 direct revenue from Willsure-surfaced reviews, plus £145,950 of freed solicitor time redeployed to chargeable client work.
"Solicitor Time Freed" values the hours Willsure releases from non-chargeable archive admin at the chargeable rate (£350/hr) - what those solicitors could earn charging their time to clients - not the firm's internal cost, since a solicitor's salary is paid regardless. For context, Willsure does the archive work for £104/Will less than the internal cost of doing it manually (£250/hr). Each change Willsure identifies that needs a Will update is also a new revenue opportunity, captured in the cash return above.

Plain-English Summary
Across 1,000 Wills at £25 per Will, the firm invests £25,000. Willsure flags 750 high or urgent-risk Wills (75% of the archive). Of these, 248 convert to a paid review (33% conversion), generating £86,800 in review fees, plus £12,500 from 50 LPA cross-sales and £47,500 from 50 IHT planning engagements. After the AI investment, the projected net cash return is £121,800 - a 487% return on investment.
Willsure also replaces 30 minutes of non-chargeable archive admin per Will with 5 minutes of AI oversight, freeing 417 hours of fee-earner time. Because a solicitor's salary is a fixed cost - the firm pays it regardless - the value of releasing them from this administrative burden is not a cash saving but the chargeable revenue they can now generate: redeploying those 417 hours to client work at £350/hr is worth £145,950. (The internal cost of doing the work manually, £104,250 at £250/hr, is shown for context only and is not added to the return.)
Combined, the net benefit to the firm - direct revenue from Willsure-surfaced reviews plus the chargeable capacity released - is £267,750. Each change Willsure identifies that needs a Will update is a further revenue opportunity, captured in the cash return above.
