Clamit launches AI courier invoice auditing tool to rid retailers of mystery overcharges

Claimit, the UK AI-powered courier claims platform, has launched the first invoice reconciliation tool designed to uncover incorrect rates, duplicate charges and delivery discrepancies buried in retailers’ courier invoices.

Claimit digests fragmented courier data into a single dashboard in real time so retailers have visibility of all their invoices and what they are being charged. The launch comes ahead of peak retail season, when parcel volumes can rise as much as 2. 5 times.

During these periods, retailers will be processing thousands of courier invoices per week, creating a steep workload for logistics and finance teams trying to compare spend to contractual rates. Invoice auditing can also reveal whether couriers have met the service levels retailers are paying for.

Claimit checks whether agreed delivery times have been honoured, helping retailers identify charges associated with late deliveries. Late shipments are the most common discrepancy identified across courier invoices. The launch comes at an important time for retailers to be scrutinising delivery performance and costs.

Over two-thirds (68%) of people who received a parcel in the UK reported a delivery issue in 2025 (Ofcom). Last year, Citizens Advice also reported that 16 million people received post late over the Christmas period from Royal Mail alone. Large retailers are often partnered with five to ten couriers, each producing weekly invoices.

Without an easy way to digest their spend, teams either have to dedicate countless hours sifting through data or just don’t have the time to do a thorough audit, especially when parcel volumes ramp up over the retail peak season.

Retailers lose thousands simply because they don’t have the visibility needed to spot incorrect charges and recover the money they’re entitled to. – Andy Watson, co-founder of Claimit There is no standard structure for courier billing, meaning retailers can receive as many as 70 invoices a week, all presented in different formats, during peak.

Claimit’s AI identifies issues in this fragmented spending data including incorrect rates, duplicate charges and weight discrepancies, and breaks them down by courier so retailers can see where overcharging is concentrated. The potential savings are significant.

In one month alone, a Claimit client successfully challenged charges relating to 20-25% of parcels sent through one courier.
