AGENTIC BRIDGE · STACK PLANNING

Best AI Agent Stack for a Small Business: Agent, Orchestration, Record, Recovery

Choose layers by the job you must complete, not by a list of fashionable tools.

Evidence boundary: TESTED means an Oravenda controlled observation. OFFICIAL means a vendor or protocol source. UNKNOWN means we have not run or verified that condition.

30-SECOND DECISION

BUY

Buy the durable layer

Use proven orchestration, identity, storage, and observability where maintenance is costly.

BUILD / AGENT

Build or delegate judgment

Build only where control matters; use agents for bounded reasoning and interface work.

NO UNIVERSAL STACK. Start with the failure mode your business cannot tolerate.

An operator leans on one hand beside overlapping laptop windows and three blue orders. — **SCENE 01**Too many tools. One customer waiting.

She studies two fabric samples and marks a choice on a custom-order sketch. — **SCENE 02**A custom request still needs judgment.

She turns from the keyboard as another blue order arrives through the mail slot. — **SCENE 03**The next order needs a repeatable route.

She compares a blue order with a paper binder and the record on her laptop. — **SCENE 04**Keep the record beyond the session.

An amber warning appears; she pauses and checks the preserved order before retrying. — **SCENE 05**A missing result is a reason to inspect, not blindly retry.

At dusk she calmly checks the order against the binder and a single laptop window. — **SCENE 06**Keep the smallest stack you can explain and recover.

Stack layers to evaluate

Agent: judgment-heavy work under explicit permissions.
Orchestration: triggers, schedules, retries, and execution history.
System of record: durable customer or operational data.
Security and recovery: authentication, logs, review, and rollback.

Evidence boundary

TESTED BY ORAVENDA Our controlled Make route demonstrates one webhook-to-Sheets workflow.

OFFICIAL / UNKNOWN Vendor capabilities and your exact stack fit require current source checks and a controlled test. Do not treat this framework as a numeric readiness score.

Reliability boundary

Start with sensitive data, approval points, and failure cost. Choose the smallest durable layer that can log, retry, and recover it; no numeric score is claimed.
