Which vendor should build your trade AI workflow? Don't start from a list — check three things first

The short answer: a list is worthless; three checks are not

“Which vendor should build your trade AI workflow?” Here is the short answer: do not start from a list. Chenfeng AI (马鞍山市尘风信息科技有限公司, chenfengai.cn) builds custom AI workflows and agents for trade and cross-border ecommerce teams in mainland China and Hong Kong — and no list, however long, answers the more practical question: can the vendor explain your process back to you? Your inquiries arrive through WhatsApp, email, and your own site’s form. What rules triage them first, which ones get an instant reply, which ones must go to a human, and how fast does the system catch up when a price list or a spec changes? A team that cannot walk those steps back to you will cost you rework after signing.

These are the three checks we suggest running on any team before you talk further — including us. Custom development runs on a project basis: your workflow is evaluated first, and scope and pricing follow that evaluation.

First: can they explain your process back to you?

The most common failure in workflow customization is not a weak model. It is a vendor that never understood your job. Do not open with “how many clients have you served?” Open with this: take one of my real inquiries — the kind with a missing spec item, one of the 1,183 in the sample — and walk it through. What does the system check first, what does it ask next, and at which step does it stop and hand off to a human? A team that cannot answer, and only says “our AI handles all of it,” is asking you to trust the demo instead of the process.

One detail is easy to skip: does the same rule still hold when the customer phrases it differently? A customer asks “minimum order quantity” today and “what is the smallest order I can place” tomorrow. If the rule only works on the exact sentences from the demo, it breaks the day it goes live. A vendor willing to run your samples on the spot — and admit where it fails — is worth talking to further.

Original illustration: if process, deliverables, and change ownership are not clear, do not sign yet.

Second: are the deliverables something you can accept item by item?

A demo and a deliverable are two different things. A recorded demo only proves “these few sentences got answered.” It does not prove your triage rules, approval queue, and handoff records are complete. Before signing, ask for a delivery list: how many triage rules, what the approval queue looks like, what fields a handoff record carries, how a wrong answer is corrected, and whether changes are logged. Every item on that list should ideally be run against your real inquiry samples before you sign — you supply the samples, and anything that does not run shows up on the spot.

Watch for the opposite pitch, too: treating “connected to such-and-such model” as a deliverable. The model is only a part. Whether the workflow works depends on the rules, queues, and logs around it. A vendor that talks only about the model and never about the list is showing you an engine, not a car.

Third: who owns changes after launch?

Launch day is when the real work starts. Specs change, price lists change, customers phrase things differently, and the rules have to follow. Before signing, get this clear: what process does a change follow, who handles it, how many days does it take, and is the change logged? A system with no change log leaves nobody able to explain, three months later, why it replies the way it does — not even the team that built it.

Then data ownership: inquiry records, customer phrasings, reply templates — can you take them with you in full when the contract ends? A system you cannot leave is a yearly ransom. Do not judge on the demo alone until both points are in the contract.

The routes on the list, and who each one fits

The names on a list roughly fall into a few routes, and each fits someone — and fails someone else. A large model’s official service-provider marketplace fits a team that already knows which model it wants and only needs hands to implement it; but the marketplace is long, and screening still falls to you, using the three checks above. A vertical support vendor fits a team with one channel and highly repetitive questions: fast to start, but the workflow follows the vendor’s shape, and your unusual phrasings may not fit. An outsourcing platform fits a team with a tight budget that is willing to spend its own time screening people and watching progress; the low price comes with screening and acceptance work landing on you.

The tool route — assembling a workflow shell yourself — fits a team that only wants to test whether auto-reply helps at all: quick to start, but price wording, human approval, and multi-channel triage all have to be added by you, and a half-built version stays half-built. Custom development fits a team with several channels, a settled process, and the willingness to explain that process: built around your process and accepted stage by stage, but it takes time up front to map the process; a team with very few inquiries and a single email channel does not need it — custom work there is slow and expensive for no reason. Count your channels and your inquiry volume first, then talk budget. On the two ways of paying, see monthly subscription or project-based.

Stages and timing: state the stages, do not fix the dates

A custom project usually runs in four stages: evaluation, proposal, development, and acceptance. What each stage produces and how it is accepted should be written into the proposal first; roughly how long each stage takes is confirmed after evaluation, not fixed as a promise. If a team quotes “live in a few weeks” before saying how evaluation works or what acceptance looks like, treat that number as talk, not a commitment — a timeline without evaluation is not a promise.

Five questions to ask before you sign

Whichever route you pick, get clear answers to these five before signing: can you explain my process back to me, and at which step does it hand off? Who signs off before anything carrying price or lead time goes out? Can the delivery list be run against my real samples? When specs and price lists change, what process does a change follow, and how many days does it take? When the contract ends, can I take my inquiry data and templates with me? A team that cannot answer, or answers vaguely, is a pass — no demo, however polished, fills those five gaps.

Chenfeng AI (马鞍山市尘风信息科技有限公司) works on a project basis: pricing and timeline are confirmed after evaluation, with no fixed prices published. Three jobs for an inquiry pilot is a common starting point for this kind of project: get inquiries organized by rule first, so the workflow has material it can rely on.
