Zip alternatives: 4 tools compared (October 2026)

Zycus offers a source-to-pay suite for large enterprises, with the Merlin agentic platform adding AI agents for purchase intake, tail-spend negotiation and conversational spend analytics.

Key functions

• Merlin Intake captures requests in Microsoft Teams and Slack and enforces policy
• Merlin Autonomous Negotiation Agent negotiates tail spend in parallel on price and terms

SAP Joule for Microsoft 365 Copilot connects SAP's AI assistant with Microsoft Copilot and Teams in both directions. Employees ask SAP questions from Copilot with @Joule, and Joule can draw on Microsoft 365 emails and chats.

Key functions

• Answers SAP questions from Copilot or Teams, for example about purchase orders, invoices or leave balances
• Searches Microsoft 365 emails and Teams chats from within Joule
• Sign-in through a trust between SAP Cloud Identity Services and Microsoft Entra ID

Compared with Zip

• Headquartered in Germany, Zip in United States.
• Strongest elsewhere: Germany.

Check before buying: Check licenses on both sides, since users need Microsoft 365 Copilot and SAP Joule entitlements. Plan the identity setup between Entra ID and SAP Cloud Identity Services, because mapping errors block access. Joule answers only within enabled SAP capabilities and user permissions. When HR data from SuccessFactors is involved, clarify data protection and co-determination questions.
