Savings claims (firm-stated): Stated by the firm, not verified
95% of invoices from 20 of a retail client's largest vendors processed without human intervention ("95% touchless"), and more than 40% greater invoice processing capacity with the same sized staff, at a lower cost per invoice.
Auxis accounts payable automation case study for one private equity-backed specialty retailer (published June 2024), shown as a teaser on the Auxis F&A outsourcing page. Automation-rate and capacity figures, not a cost saving: the 95% covers 20 vendors only, the cost reduction per invoice has no figure, and baseline and period are not stated.
70% touchless invoice processing, equivalent to freeing up more than 2,500 human hours per month; a 75% increase in invoice volumes absorbed with the same-sized AP team.
Auxis healthcare AP automation case study for one U.S. healthcare system (published April 2024), shown as a teaser on the Auxis F&A outsourcing page. Automation rate, not a cost saving: the case study says the cost per invoice fell significantly without a figure, and baseline and period are not stated. Auxis says it helped the client set a realistic target for the touchless share and that the target typically falls between 60-80% depending on a client's circumstances.
Grant Thornton says the operate-to-transform model uses guaranteed outsourcing savings to fund AI and automation (C-4253) but gives no savings figure. The two figures recorded are automation rates from two of the Auxis case-study teasers shown on the Auxis F&A outsourcing page (C-5046): single-client results stated by the firm, not cost savings.

Questions to ask

For this offering

If Grant Thornton audits our financial statements, has our audit committee pre-approved this service, and how does Grant Thornton assess it against the SEC non-audit service categories (bookkeeping, financial information systems design and implementation, internal audit outsourcing, management functions) and, for ICFR-related work, PCAOB Rule 3525? Ask our audit committee and counsel to confirm.
Which entity would contract for the service, Grant Thornton Advisors LLC or another, and how does that interact with Grant Thornton LLP's audit relationship with us?
How are guaranteed savings defined, measured and paid, and how is that structure assessed against the contingent-fee rule where Grant Thornton is the auditor?
Which AI and automation would run in our processes, and does any of it post or approve transactions?
Where would our data be processed across the Latin American and other delivery centers?
