Job by job
Keeping guests in the loop
NotLost's own FAQ says seekers receive two emails, one to confirm and one with the outcome. Boomerang sends co-branded updates at every step, lets staff ask a guest a specific question from the claim, and gives guests an account with status, payment and tracking. A UK theme park sent 40,000+ automated updates and tripled its return rate in three months.
Verification at handover
NotLost leaves final validation to the venue and records who returned what. Boomerang does the same and adds a second check: the guest compares what your team logged with what they described and approves before anything ships. In person, staff can capture a signature, an ID and recipient details.
Paying the program back
Guests pay fair shipping. Boomerang offers multiple revenue-share opportunities, and partners on average earn back upwards of 25% of their annual contract value every year.

Questions
Does Boomerang work in the UK?
Yes. UK partners ship domestically with Royal Mail, and we work with UK venues today, including a UK theme park that tripled its return rate in three months.
Can guests see our inventory?
No. Guests describe what they lost and your team verifies ownership, so IDs, cards and phones are never shown publicly.
Can we bring our existing inventory over?
Yes. We bulk import your open inventory as part of go-live, so the whole back room is searchable on day one and nobody has to log it twice.
Is Boomerang secure enough for our IT review?
SSO over SAML or OIDC, custom roles with granular permissions, access limited by location, idle session timeouts and a full activity history on every item and claim. We regularly complete vendor security reviews. Ask us for our security documentation.
How is Boomerang priced?
An annual platform subscription sized to your venues and volume, with every new feature included as it ships. Guests pay fair shipping. Boomerang offers multiple revenue-share opportunities, and partners on average earn back upwards of 25% of their annual contract value every year. Book a demo and we will scope it with you.
