AI Account Manager Agent for B2B eCommerce (2026)

Account managers do not need another BI login. They need which accounts require attention today — missed cadence, quote about to expire, quality cluster, credit hold, first order stuck in onboarding — with evidence, not a vibe.

On 17 June 2026, AgentCore Harness reached GA (What’s New). A scheduled, schema-constrained brief is a Harness job. After 30 July 2026, Classic is the wrong host.

This post is a dashboard contract. The table below is demo fixtures. It is not a FactualMinds book-of-business report.

First-party signals we reuse (not AM quota outcomes) — Gateway server-side tools cut median tool RTT ~180 ms → ~95 ms on a B2B CRM assistant (12 tools, ~8k turns/day) — Gateway post. That canary is the right analog for an AM tool mix. Platform ~$791/mo at 50K sessions is not your Salesforce bill (decision guide). Model morning invokes on the AgentCore pricing calculator.

Reproduce this — Copy b2b-account-health-dashboard.md. Every priority needs evidence_tool. Folder: ecommerce-ai-agents-series/.

Opinionated take: ship a five-row attention list from named account tools. Do not give the AM agent a warehouse clone or a “health score” you cannot recompute. Trade-off: novel questions wait for a new tool. You keep PII and leaked nets out of 8 a.m. Slack.

Cadence rows come from the reorder playbook. Own-account sales UX is the sales agent. Site-level morning brief (different grain): operations agent. Lifetime-value math is a later series post — CLV agent — do not invent an LTV number in this brief.

What the AM assistant reads

Associate JWT + assignedAccounts. Buyer JWT never sees this dashboard. Bedrock = model. Gateway + Cedar = boundary. Browser off. No payment capture. No native Shopify connector.

Accounts requiring attention today (example)

Demo only. Replace IDs. Do not treat dollar amounts as client KPIs.

Watch: ACC-DEMO-088 qty down vs last 3 POs — not in the five.

Same evidence_tool rule as the ops brief schema. Rank by blast radius, not confidence. Cap 5.

What each column is allowed to mean:

• Revenue / orders — windowed totals from tools, not a model-estimated book.
• Quotes — open count and amount from CPQ. Over-cap rows still need HITL to issue — quote agent.
• Tickets — helpdesk ids. A quality cluster is do_not_contact, not a cheer-up call.
• Cadence — from the reorder playbook. Late ≠ “email them.”
• Next action — an action code, not a paragraph. AM executes.

Do not put net SKU price for the whole book of business in Slack. Assigned-account getCustomerPrice belongs on a sales turn, not a team paste. Do not invent LTV in this brief — CLV post is a different scorecard when it ships.

Site ops (stock-out on an advertised SKU, refund cluster) stays on the operations agent. One Slack channel that mixes “pause the ad” with “call Northline” will be ignored.

Context: one expanded card; fixture JSON.

{
  "accountId": "ACC-DEMO-104",
  "asOf": "2026-08-27",
  "cadence": { "expectedDays": 30, "daysSinceLastOrder": 38, "tool": "getOrderHistory" },
  "recommended_action": "call_am",
  "contact_customer": false
}

What broke

What broke — An AM “health score” (0–100) with no tool lineage, pasted into Slack with net prices for the whole team. One screenshot left the channel. Detection: DLP on Slack plus a buyer asking why a competitor’s net appeared in a recap. Fix: kill the opaque score; markdown columns only; getCustomerPrice off the brief; assigned-account Cedar; cap five. Lesson: a dashboard is a permission set, not a pretty table.

Engineers still watch AgentCore Observability. AMs do not. Do not ship a fake AWS console screenshot as “the product.”

Gateway ~180 → ~95 ms is why we keep tools server-side on Gateway. ERP will still dominate p95.

The HITL queue is the AM’s job list, not a second model turn that “sends something nicer.” Attach session id and tool trace. Prove a buyer JWT cannot invoke the brief. Prove shopper cannot either. That is the same Identity pattern as sales — different tools.

A Next.js AM console is optional. Slack with a JSON template that can only render the five rows is valid. A CloudWatch screenshot is not. Harness for the schedule; Gateway for the reads; Cedar for account scope. Bedrock stays the model.

Demo dollars in the table are fixtures so you can copy columns. Replace them. Do not cite them as a FactualMinds book-of-business result.

What to Do This Week

1. Paste b2b-account-health-dashboard.md into the RFC.
2. List assigned-account claims. Prove a buyer JWT cannot invoke the brief.
3. Named reads only. Policy LOG_ONLY. No send-email tool.
4. Ten goldens: five-cap, credit hold, quality cluster, cross-account DENY, invented LTV.
5. Wire cadence codes from the reorder agent.
6. Harness schedule. Not Classic after 30 July 2026.
7. Contact us · Amazon Bedrock.

What This Post Doesn’t Cover

• Storefront B2B sales chat — sales agent

• Site-wide ops priorities — operations agent
• CLV models and cohort math
• CloudWatch-as-AM-UI
• Measured quota attainment from a client — we are not inventing it

FAQ

When should you NOT build an AI account manager agent?

No assigned-account scope, or the brief is a SQL copilot. Skip Classic after 30 July 2026.

What could go wrong if you rank accounts by model confidence?

Twenty P1s. Rank by stored blast radius. Cap five.

What could go wrong if the dashboard includes another account net price?

Price-book leak. Keep nets off the team brief.

Is this the same as the store operations morning brief?

No. Account grain vs site grain.

Should the AM agent email the customer?

Not in week one.

Can we screenshot CloudWatch and call it the AM dashboard?

No. Use the markdown contract.
