Who supports an ERP after go-live?
Ongoing ERP Support and Managed Services: What The Shortlist Report Finds
10 firms lead, appearing in 20.0–36.4% of 55 AI responses. The sample cannot separate them, so we do not pretend it can.
No clear leader
No single firm dominates this question. Ten come up regularly and they specialise in different things, so the firm worth calling is the one that fits your situation rather than whoever sits highest.

Key findings
- No firm answers “Who supports an ERP after go-live?” reliably in ChatGPT. The most-named, EPIQ, appeared in 20 of 55 responses (36.4%) collected August 11, 2026–August 19, 2026, and 9 other firms scored close enough that the sample cannot put any of them in order.
- EPIQ, RSM and Deloitte were named most often, in 12–20 of 55 responses. All 10 firms in the leading group are listed with their counts in the table below.
- 10 firms cleared the reporting threshold on “Who supports an ERP after go-live?” in ChatGPT as of August 19, 2026; the full table with response counts is below.
- RSM appears in 6 of the 9 NetSuite and ERP implementation partners reports published by The Shortlist Report, the widest coverage of any firm named on this page.
- No firm paid to appear in this ranking; placement cannot be bought, and the counts come from ChatGPT responses rather than from submissions.
Why the tiers fall where they do
Tier 1 holds EPIQ, RSM, Deloitte, Accenture, Capgemini, Cognizant, eMerge Technologies, HCLTech, IBM and Infosys, named in 11 to 20 of the 55 ChatGPT responses. They are grouped rather than ranked because the gaps between them are inside the margin of error at this sample size — one extra mention would reorder them, so an order would be reporting noise as a finding.
The test is McNemar’s at 95%, applied against the same 55 responses for every firm. The full reasoning, and what happened when we ranked one-to-N instead.
What the sample shows
10 firms lead this question: EPIQ, RSM, Deloitte, Accenture, Capgemini, Cognizant, eMerge Technologies, HCLTech, IBM and Infosys. They appear in 20.0–36.4% of the 55 responses. The gaps between them are inside the margin of error at this sample size, so they are listed together rather than ranked against each other.
134 firms were named at least once across the sample. 10 of them cleared the threshold of 2 responses and appear above; the rest were named once and are inside the noise.
How to read this
Firms are grouped into tiers, not ranked one to fifteen. A tier holds every firm whose 95% confidence interval overlaps the leader's, which is a long way of saying the sample cannot tell them apart. Order within a tier is arbitrary — read the counts, not the position.
Share is the percentage of responses that named the firm — not a quality score. A firm scoring low here may be excellent and simply under-written about online, which is a finding about its visibility rather than its work.
The same question was asked repeatedly because AI assistants do not answer identically twice. A single response would tell you almost nothing.
What this measurement does not tell you
- It is not a quality ranking. Share reflects how much has been written about a firm online, which is what an AI assistant reads. A capable firm nobody writes about scores low here.
- It is a reading from a date range, not a permanent standing. This sample was collected August 11, 2026–August 19, 2026; models change and so do their answers.
- It covers ChatGPT only. Other assistants answer differently, and we do not extrapolate across engines we have not measured.
- Order within a tier is arbitrary. Read the counts, not the position. Why we use tiers.
