SAP runs an annual license-measurement program through its Global License Audit & Compliance (GLAC) team, and its highest-value finding remains indirect and digital access — third-party systems touching SAP data. This page maps SAP's measurement mechanics across named users, engines, and digital access, lists the firms that defend and negotiate them, and indexes coverage by service and by country.

Audit pressure across enterprise software is near a structural high: 62 to 63 percent of organisations reported a software audit within a rolling 12-month period (2024 to 2025 industry surveys, indicative), and 52 percent now bring in outside defense help. Around 30 percent of organisations report having been audited by SAP at least once (2025 surveys, indicative), placing it among the most audit-active publishers alongside Microsoft, IBM, and Oracle.
SAP's defining exposure is indirect and digital access. Its 2018 document-based digital-access model recast how third-party systems touching SAP data are licensed, and that remains the signature high-value finding. The 2027 deadline for mainstream maintenance of legacy SAP ECC is pulling customers toward S/4HANA and RISE conversions, and those conversions are increasingly the moment SAP re-measures a customer's position. SAP is described here factually; the point is not that its program is unusual but that its metrics are distinct and reward precise preparation.
The recurring mechanics. Recognise them early and you keep leverage.
An annual self-measurement via USMM, consolidated across systems with the License Administration Workbench, classifies users and counts engine and document metrics.
Third-party systems reading or writing SAP data without a named user. The 2018 document model licenses the documents created, and is SAP's highest-value claim.
Professional, limited-professional, and employee user types carry very different prices. Misclassification inflates the bill; reclassification is core to the defense.
Engines (payroll, e-recruiting, and others) are licensed on their own metrics — records, orders, or gigabytes — separate from named users.
Conversion re-bases users, engines, and digital access, and is often the moment SAP re-measures. Treating it as a licensing event is where the leverage sits.
The 2027 ECC maintenance deadline pulls customers toward conversion, and conversion-linked measurement shapes the negotiation calendar.
| Area | How it is licensed | Common finding |
|---|---|---|
| Named users (ECC / S/4HANA) | Per user, by type (professional, limited, employee) | Over-classification of users into higher-priced types |
| Indirect / digital access | Document-based (2018 model) or named user | Third-party systems creating uncounted documents |
| Engines | Per engine metric (records, orders, GB) | Engine usage beyond the licensed metric |
| S/4HANA / RISE | Subscription or conversion-based | Re-based position at conversion |

This is a directory, not a league table. Firms appear in neutral alphabetical order by firm name. We do not score them, rank them, or tell you which to pick, because the right firm depends on your vendor, your jurisdiction, and your situation, not on our opinion.
Every firm carries a short, balanced set of pros and cons written in the same register. The cons are real, not softened marketing. Two facts matter most when you weigh them for yourself. Independence is listed as a pro: a buyer-side firm with no vendor partnership, no reseller relationship, and no commission has no incentive to sell you more licenses. A reseller relationship, a Big Four audit appointment, or vendor-side audit work is listed as a con, because it is a potential conflict of interest with buyer-side work. Neither is a verdict. They are trade-offs you weigh against price, depth, and jurisdictional fit. The matching service can route your brief to firms covering your situation, but the choice of firm is always yours.
We route your brief to firms covering SAP audits and negotiations in your jurisdiction. The directory and matching are free for buyers. We are not a law firm and take no money from software publishers.

Indirect access is when a third-party system — a CRM, a bot, an e-commerce front end — reads or writes SAP data without a named user logging in. Since 2018 SAP offers a document-based digital-access model that licenses the documents those systems create rather than the users, and mismatches here are SAP's signature high-value finding.
SAP customers run an annual system measurement using the USMM tool, consolidated across systems with the License Administration Workbench (LAW). The output classifies named users by type and counts engine and document metrics; getting user-type classification and document counting right is central to the result.
It can. An S/4HANA or RISE conversion re-bases user types, engines, and digital-access counts, and SAP's measurement is often tied to the conversion. Treating the conversion as a licensing event, not just a technical one, is where most of the leverage sits. This is information, not advice.
