Coupa Supplier Portal
Supplier AI Agent Platform
Vision, architecture, and resourcing proposal for an agent-first supplier experience on CSP.

1 / 8Strategic Context
Why now
- Capability is expanding faster than UX can absorb. Invoice Smash, Strategic Views, supplier profiles for marketing teams, and a potential PIM acquisition are all converging on CSP. Each adds screens and workflows. A modular agent with skills integrates them into one experience without scaling UI complexity.
- Navi's ceiling. Today Navi tells suppliers how to use the portal. It doesn't process invoices, surface insights, or do work on their behalf. Each new capability requires a new engineering project.
- The models have turned a corner. Since December 2025, foundation models and agent harness architectures have become dramatically more effective. Anthropic crossed $10B ARR this year. Claude Code went from zero to ~600K downloads in 60 days. The capability is here — the question is whether we build on it now or react to it later.
Architecture
From workflows to a platform
Navi Today
Target Architecture
The Unlock
Cross-context reasoning
When one agent sees invoicing, catalogs, verification, and transaction patterns together, suppliers can ask strategic questions that siloed workflows can never answer.
"Which of my invoices are overdue, and which buyers are consistently paying late?"
"I'm seeing fewer POs this quarter — what changed in my buyer connections?"
"How is my company showing up in buyer searches, and what can I do to improve visibility?"
Today each question requires navigating multiple screens and synthesizing data manually. The agent does it in one turn.
4 / 8Near-Term
First capabilities
Invoice Smash
Upload invoices, validate against POs, flag discrepancies. 96K monthly users touch this flow today — the agent makes it one conversation.
Strategic Views
Surface payment trends, buyer behavior, and AR insights without navigating between dashboards. Attacks the CoupaAdvanced activation gap directly.
Verification & Profile
Automate the 206-supplier manual verification workflow. Guide profile enrichment for buyer discovery. Reaches marketing teams who don't use the portal today.
Each capability is a skill file + API wrapper — not a new engineering project.
5 / 8Execution
Phased plan
Workstreams A and B run in parallel. POC starts when both have enough surface area to wire together. Decision point at POC completion: scale investment or adjust scope.
6 / 8What We Need to Resolve
Open questions
Product Experience
Chat interface, inline contextual assistance, proactive suggestions, or a combination? The product surface determines adoption. Resolved in Phase 1 via prototyping.
Cloud Architecture
Isolated VMs vs. containers? Hosting model, cost structure, and scaling approach for concurrent sessions with strict tenant isolation. Mikael brings direct experience here.
Security & Compliance
Tenant data isolation, full audit logging, and enterprise compliance for a system with model-driven autonomy. Infrastructure-level enforcement, not prompt-level.
These are the three unknowns we close before scaling investment. Each has a clear resolution path within the POC phase.
7 / 8The Ask
Resourcing the POC
Two configurations. Both start immediately — no hiring delay.
| Role | Allocation | May–Dec cost |
|---|---|---|
| Spencer | Full-time | Existing headcount |
| Mikael | 10–15 hrs/wk | $105–158K |
| Senior Dev | FTE | ~$133K |
| Junior Dev | FTE | ~$87K |
May–Dec total: ~$325–378K
+ hiring lead time & coordination overhead
| Role | Allocation | May–Dec cost |
|---|---|---|
| Spencer | Full-time | Existing headcount |
| Mikael | 25–30 hrs/wk | $263–315K |
| Senior Dev | FTE | ~$133K |
May–Dec total: ~$396–448K
Proven partnership, AI-amplified, move immediately
Costs are for May 1–Dec 31, 2026 (35 weeks). Mikael at $300/hr. FTE estimates are fully loaded (~$200K/yr senior, ~$130K/yr junior) pro-rated to 8 months. Spencer is existing headcount, excluded from totals.
