The Challenge
GPO roster management is consuming your team
Pharmaceutical and distribution companies manage dozens of GPO relationships, each with its own roster format, membership rules, tier structures, and admin fee schedules. Manual processes lead to overpayments on ineligible members, missed tier thresholds, and admin fee errors that compound across millions of transactions.
- Rosters arrive in different formats from every GPO — no standardization
- Member eligibility changes constantly and your data is always behind
- Tier threshold tracking lives in spreadsheets nobody trusts
- Admin fee calculations are manual, error-prone, and hard to audit
The IMA360 Approach
One platform to govern GPO roster operations.
- Automate roster ingestion and normalization across every GPO format
- Validate member eligibility in real time against contract terms
- Track tier commitments and threshold progress automatically
- Calculate and reconcile admin fees with full audit trails

Frequently Asked Questions
Which GPOs does IMA360 support?
IMA360 supports all major GPOs including Vizient, Premier, HPG, Intalere, and any other group purchasing organization. The platform normalizes roster data from any format — regardless of how each GPO delivers their membership files — so your team works with clean, standardized data across every relationship.
How does IMA360 validate member eligibility?
IMA360 validates member eligibility in real time against contract terms, DEA registration, 340B covered entity status, and GPO-specific membership rules. The platform flags ineligible members before chargeback claims are processed, preventing overpayments and ensuring only qualified members receive contract pricing.
Can IMA360 calculate GPO admin fees automatically?
Yes. IMA360 calculates administrative fees based on each GPO's specific fee schedule, contract terms, and transaction volumes. Fee calculations are fully auditable — every amount is traced to its source transaction and contract provision, eliminating the spreadsheet-based calculations most companies rely on.
How does GPO roster data connect to our chargeback process?
IMA360 integrates GPO roster eligibility directly with your chargeback workflow. When a chargeback claim arrives, the platform validates the member against current roster data in real time — ensuring you only pay chargebacks for eligible members at the correct contract price. This closes the gap between roster management and chargeback processing that causes most overpayments.
How long does implementation take?
Most GPO Roster Management implementations go live within 6 to 18 months. IMA360's pre-configured GPO templates and roster import connectors accelerate deployment. Your team can begin processing rosters and validating eligibility as soon as your GPO data feeds are connected.
What systems does IMA360 replace?
IMA360 replaces a wide range of legacy and point solutions for pricing, rebate, chargeback, and incentive management. Organizations commonly migrate to IMA360 from SAP Vistex, SAP Condition Contract Management, Model N, Vendavo, PROS, Zilliant, Pricefx, and custom-built or spreadsheet-based solutions. Because IMA360 is ERP-agnostic and API-first, it works alongside any ERP system and replaces tools that lack modern integration, automation, or cross-functional visibility.
