E-commerce AI Service Procurement: Scope and Cost across Build, SaaS and Delivery Partners

Give offers the same task

Define service work, users, sources and permitted actions before comparing proposals. Policy lookup, shipment status and reviewed order preparation need different data and authorities. Chat capability alone is not a common acceptance scope.

Building an application need not mean training/owning a model or using vectors. It may call hosted models or existing APIs. A delivery partner may configure a purchased platform. Build method, deployment location and delivery team are separate choices that can be layered.

Compare cost and control within scope

Actual architecture, capabilities and contracts should answer these questions, rather than category rankings.

Estimate full cost for equal workload, peaks, quality and period. Retain dated quotes and assumptions. Fixed capacity or self-hosting does not establish zero request cost; SaaS billing is not universally linear in conversations.

Saved time may provide capacity before reducing spending. The UK Efficiency Framework (updated November 24, 2025) makes that methodological distinction, not Taiwan commerce pricing or accounting rules.

Check capabilities, not labels

Intercom's connector FAQ describes configurable API reads/updates and multi-step procedures. One SaaS capability counters the claim that only custom systems can handle such work. Check version, availability, interfaces and actual acceptance; documentation does not establish merchant results or persistent memory.

Combine direct queries, retrieval, preparation and human handling as appropriate. Layering does not authorize RAG to decide refunds or monetary disputes. Retrieval supplies information; consequential actions require their own rules and authority.

Separate policy from transaction authority

Check market, policy version, transaction conditions, authoritative sources and consumer rights. Article 19 of the Taiwan Consumer Protection Act starts the eligible distance-sale rescission period at receipt of goods/services, with reasonable exceptions. Internal policy alone does not establish that applicable rights can be narrowed. Responsible owners must assess the particular transaction and product exception.

Assess the effect of opening under applicable rules and case conditions. The source displays a June 17, 2015 amendment date; this reference covers Article 19’s general boundary, while implementing product exceptions require separate checking.

Establish identity, order, allowed actions, approval and failure handling. Use only necessary task data, not automatically full member history. Intercom's API design guide (June 15, 2026) discusses identity, minimum data and server-side logic, not the merchant's actual authorization.

Purchase against acceptance and handover

Use the same representative questions, missing/conflicting evidence, denied access and failure cases across offers. Compare support, applicability, complete handling time and review burden. First response, resolution and successful order changes are different endpoints.

Agree owners, source updates, exceptions, support and exit before selecting the configuration. Internal or provider hosting still requires actual processing/rights checks, not a label in place of a contract.
