Supplier Follow-up Agents for a Trading and Distribution Company

A concept build for the purchasing team of a UAE trading and distribution company that chases overseas suppliers by hand for order confirmations, ship dates and shipping documents. Four agents split the work: a planner picks the orders that need chasing, a researcher gathers the facts, a writer drafts one email per supplier and a reviewer checks every figure against the sources. A buyer approves each email before it goes, so nothing reaches a supplier on its own.

The brief

The problem this concept answers

A typical trading company in the UAE buys from suppliers several time zones away and resells to retailers and contractors across the region. A small team of buyers looks after a long list of open purchase orders, and each one needs the same chasing: has the supplier confirmed it, when will it ship, where are the packing list and the commercial invoice, has the booking moved. Buyers do it from their own inboxes when they have a moment, so follow-ups are uneven, the expected dates in the ERP go stale, and sales promises customers delivery dates the supplier changed a week ago. The work is repetitive enough to automate and risky enough that nobody wants software writing to suppliers unchecked: one wrong date, or a sentence that sounds like a commitment on price, costs more than the time it saves.

In the first version

  • Open purchase orders read from the ERP
  • One follow-up email per supplier, in its existing thread
  • Replies read for new ship dates and attached documents
  • A morning approval queue for buyers

Left out on purpose

  • Writing to the ERP: buyers update dates in the first version
  • Negotiating prices, terms or penalties, which stay with buyers
  • Payments and bank-detail changes, which stop the run and go to finance

Design decisions

  • Rules choose who is chased; models choose the words

    Whether an order needs a follow-up is a rule the buyers set and can read. The models group orders, gather facts and write, so the number of emails each morning is predictable and never decided by a model.

  • Supplier email is data, never instructions

    Text in a supplier’s reply is extracted into fields and never followed as an instruction. A reply that asks for a new recipient, a different bank account or changed terms is flagged for a person instead of answered.

  • Step and spend caps on every run

    Each order’s run has a ceiling on steps, tool calls and model spend. A run that reaches it stops and appears in the queue with its trace, rather than retrying quietly in the background.

  • The buyer’s voice, the buyer’s name

    Drafts follow each buyer’s own templates and sign-off, so suppliers keep hearing from the person they already deal with, and the approving buyer’s name is on every email that goes out.

Sample run

One run, step by step

One supplier, three open orders, one approvalSample data
  1. Planner selects three ordersRoutine

    Three open orders with one supplier: no confirmed ship date five days after issue.

  2. Researcher gathers the factsRoutine

    Order lines, the last reply in the thread and the forwarder booking, each with a source.

  3. Writer drafts one emailRoutine

    One email for the three orders, asking for ship dates and the packing list.

  4. Reviewer returns the draftNeeds care

    The draft says 12 May; the order says 21 May. Rewritten, then passed.

  5. Buyer approves the emailA person takes over

    The buyer edits one line and approves; it is sent in the supplier’s thread.

  6. A reply mentions new bank detailsStopped

Build plan

How we would build it

Typical timeline
5–7 weeks from the follow-up rules to a supervised pilot with two buyers
Stack
  • Planner, writer and reviewer calls (OpenAI, Anthropic Claude or Google Gemini)
  • ERP API, read-only
  • Shared purchasing mailbox API
  • Your freight forwarder’s booking API
  • Follow-up tracker (Supabase)
  • Orchestration (n8n or Cloudflare Workers)
  • Run traces and audit log
  1. Write the follow-up rules with the buyers

    We go through a month of supplier threads with the buyers and write down when an order needs chasing: no confirmation a set number of days after issue, a ship date coming up with no documents, a booking that moved. Those rules, not a model, decide which orders get a follow-up, and the buyers own the thresholds.

  2. Four agents with four permission sets

    The planner reads open orders from the ERP and groups them by supplier. The researcher gets read-only tools for the order lines, the supplier’s email thread and the forwarder’s booking status. The writer can only create a draft in the shared mailbox. The reviewer has no tools at all: it compares the draft with the researcher’s facts and passes or returns it.

  3. A review checklist and a hard-stop list

    The reviewer’s checklist is written with the buyers: every order number, date and quantity in a draft must appear in the facts, the email must not commit to prices, payment terms or penalties, and it must go to the contact the ERP holds for that supplier. A reply that mentions changed bank details or asks for payment stops the run and goes to finance.

  4. A morning approval queue

    Drafts land in one queue each morning with the facts and the reviewer’s result beside them. The buyer edits, approves or rejects; only approved drafts are sent, from the shared purchasing mailbox and in the supplier’s existing thread. Rejections are kept with the buyer’s reason and become test cases for the next change.

  5. Replay past orders, then a supervised pilot

    Before anything is sent, a few months of past orders run through the agents and their drafts are compared with what the buyers actually wrote. A pilot with two buyers and a handful of suppliers then runs for three to four weeks, and more suppliers join only when the review results hold.

Typical targets

What we would measure it against

Targets for a typical business of this kind, not achieved results. A real project measures its own baseline first.
  • Typical target

    50–70% less buyer time spent chasing suppliers

    Basis: Chasing time logged by the buyers for two weeks before the pilot, compared with time spent reviewing drafts during it

  • Typical target

    A draft ready the same morning for every order past its confirmation window

    Basis: Design property: the planner’s rules run on every open order daily; checked as the share of due orders with a draft in the pilot

  • Typical target

    No email reaches a supplier without a buyer’s approval

    Basis: Design property: the send tool accepts only drafts that carry an approval record

  • Typical target

    Every date and order number in a sent email traced to a source

    Basis: Design property: the reviewer returns any draft with a figure missing from the facts; audited on a sample of sent emails

Your project

What a real project adds

  • A tool allowlist you sign off

    Every action the agent may take, with its read or write scope and which ones need a person’s approval first.

  • Traces you can audit

    Each run records the plan, every tool call with its inputs and outputs, and the approval decisions.

  • An evaluation set from your cases

    Real examples from your backlog scored before every prompt, tool or model change goes live.

  • Limits on spend and scope

    Step and cost ceilings per run, so an agent that loops or meets bad data stops and asks instead of carrying on.

Decisions this concept leaves for scoping

  • Writing to the ERP: buyers update dates in the first version
  • Negotiating prices, terms or penalties, which stay with buyers
  • Payments and bank-detail changes, which stop the run and go to finance

FAQ

Questions about this build

Is a distribution company running these supplier agents today?

No. This is a concept build: a worked example of how we would set up follow-up agents for a typical UAE trading and distribution company. The orders, suppliers and emails in the sample run are sample data, and the time-saving range is a typical target that a pilot would measure against your own baseline.

Why use four agents instead of one assistant?

Because the roles need different permissions. The researcher may read the ERP and the mailbox, the writer may only create drafts and the reviewer has no tools, so a mistake in one role cannot reach a supplier by itself. Smaller roles are also easier to test one at a time. The cost is more model calls per order, which is why we split the work only where the permissions differ.

What stops an agent from sending a supplier the wrong date?

Three layers. The reviewer returns any draft whose order numbers, dates or quantities are not in the researcher’s facts; the buyer reads the draft beside those facts before approving; and the send tool refuses anything without an approval record. Each run also has step and spend limits, so an agent that loops stops and flags the order instead.

Can the agents update the expected delivery dates in our ERP?

Not in the first version. When a supplier replies with a new ship date, the researcher records it in the follow-up tracker with the email it came from, and the buyer updates the ERP. Writing back to the ERP is a second phase, with its own narrowly scoped API key, once the pilot shows the extracted dates are reliable.

What happens when a supplier stops replying?

The buyers set an escalation ladder in the rules, for example a second follow-up after a few days and then an alert to the buyer and to the sales owner whose customer order depends on that shipment. The agents never threaten penalties or change terms; a supplier who stays silent becomes a phone call for a person.

Catalogue Enrichment Agent for an Online Marketplace

A concept build for a US online marketplace where sellers upload products with thin titles and half-empty attributes. An agent reads each new listing and the supplier’s spec sheet, fills category attributes and a description from that data only, validates the result against the category schema and sends it to a merchandiser for approval. Nothing publishes without a person.
