AI for customs document coordination

Short answer

An AI agent for customs document coordination gathers the invoice, the packing list and the correspondence on the right shipment, points out the missing information, prepares a question for the sender and attaches the reply to the same case. The customs specialist receives a complete set with the history of clarifications. The agent costs from €3,000 net at Syntalith and, with 400 shipments a month, pays back in 1.0 month.

Statistics

Logistics and AI: statistics 2026

1.0 mo.

payback of a €3,000 agent with 400 shipments a month: €3,490 of coordination today, €539 with checking and the model. Scenario.

Figures checked: 22 October 2026

Units and cartons describe the same shipment

The customs agent asked for the invoice and the packing list. The invoice gives quantities in units, the packing list describes cartons, and nothing in the materials links the contents of the cartons with the invoice lines. Different units do not mean an error, but the coordinator needs to know how the goods were packed.

The sender then knows which clarification is needed and does not send back a general reply. An employee checks the question and sends it with a reference to the shipment. Until the sender describes the packing, the number of units in the cartons stays unknown.

Materials go back to the case they belong to

The flow of shipment documents
  1. 01CollectionThe invoice, packing list and emails land on one shipment.
  2. 02GapThe agent points out the missing link and prepares a question.
  3. 03ReplyThe completed attachment goes back to the same case.
  4. 04CheckThe coordinator compares it with the invoice and the list.
  5. 05HandoverThe specialist receives a complete set with the history of clarifications.

The sender's reply may reach someone other than the person handling the shipment, so linking the documents lets a colleague take over the work without asking again. The shipment shows the latest request, the replies received and the material waiting to be checked. If the specialist asks for a further clarification, the coordinator goes back to the sender with a specific question and the document it concerns. When the system confuses fields even though the document is readable, the article on extracting data from freight documents will help.

What it costs and when it pays back

Scenario: 400 shipments with customs clearance a month
Today
400 shipments × 15 min = 100 h (€3,490)
With the system, a person checks the output in 15% of the time
€524
Model, 2 calls per case, Claude Sonnet 5.5
€16
Cost of one case
€8.73 today, €1.35 with the system
Saving
€2,951 a month

Payback of €3,000

1.0 month

The volume, the time and the checking share are the scenario's assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat. Model: 8,000 input and 600 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026.

What the carrier's portal already handles

Walk one shipment through your current portal. DHL describes electronic document submission, adding forms, and storing and downloading files.

A portal or an agent
  • The sender completes materials in the portal, questions go there too

    the workflow in the carrier's portal

    no new application

  • Few cases a month

    a document list with links and a responsible person

    no new application

  • Correspondence outside the portal, many shipments

    an agent that links files and replies with the shipment

    from €3,000

An agent has the most to do where correspondence runs outside the portal and someone has to read a clarification, link it to the shipment and go back for what is missing. The first scope is one document flow between the coordinator and the customs specialist, without filing customs declarations. Your team names the document sources and the people who assess the materials, and on a finished case we check whether the coordinator finds the missing clarification and passes the right file versions to the specialist. Bring to the call the last case in which the documents arrived but someone had to ask the sender what they meant. AI in transport and logistics describes the wider choice.

a month for retyping 1,000 CMR and POD documents

Payback: 2 mo.

3 minutes per document and checking in 15% of the old time are our assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. We use it here in place of a transport sector wage. Model cost: 0.007617 USD per reading, measured in our system, which is about €0.0069 per document, at the ECB rate of 1.1205 USD per euro on 22 October 2026.

foap.comcustomer service

foap.com customer service: 95% of replies are sent automatically.

Users from several countries write to foap.com, in several languages. The system reads the entire conversation and the terms of that person, and then sends a response in that person's language. Questions about money and exceptions go to the team with a ready draft, so they have to check and send them.

We establish a prototype during a free analysis.

Data checked on October 25, 2026.

„Is my data safe?”

Yes. You choose where they go: from your company account to the model on your server.

  1. 00Employee's private account

    Customer and company data ends up in an account that the company cannot see or control. There is no data processing agreement, so it is a violation of the GDPR. When an employee leaves, the chat history goes with them.

  2. 01ChatGPT or Claude corporate account

    The provider does not use your data to train models. A copy of the queries remains in his logs for up to 30 days.

  3. 02API with zero retention (ZDR)

    The provider processes the request and does not save anything. It requires his consent, we prepare the application together.

  4. 03Processing in the EU

    Queries are counted and stored in Europe: OpenAI in the EU region, Claude via clouds with the EU region.

  5. 04Model at your place

    The open model runs on your server or in your cloud in the EU. The data does not go outside the company.

What we do with every implementation

  • Confidentiality agreement and data processing agreement before we receive any data.
  • You choose the cases for the prototype and we anonymize them upon request.
  • The data stays in the EU and we delete it after the test.
  • Corporate accounts with an administrator on your side.

When data cannot leave the company

The open model runs on your server or in your cloud in the EU. To choose from:

White-tailed eagle
Polish model, SpeakLeash and ACK Cyfronet AGH
PLLUM
Polish model, HIVE consortium commissioned by the Ministry of Digitization
Qwen
Alibaba
GLM
Zhipu AI
DeepSeek
DeepSeek

We select a model for the task and check it on your cases. We run it, tune it and maintain it.

Do you have a lot of your own data? We will fine-tune the small model.

  1. 1 Your examples
  2. 2 tuning
  3. 3 test on new cases
  4. 4 model at your place

When you have thousands of similar emails, documents or reports, we teach a small open model based on your examples. It works for you, responds quickly and costs less to maintain than a large model. We measure quality on issues that the model has not seen while learning.

Przemysław and Piotr did it in large programming and consulting companies. Artem did it before and does it today at Syntalith. It's about models on your own infrastructure, tuning and quality measurement.

Questions

  • How does an AI agent help with customs documents?

    It gathers the documents and correspondence on the right shipment, points out the missing link, for example between units on the invoice and cartons on the packing list, prepares a question for the sender and attaches the reply to the case.

  • Does the agent file the customs declaration?

    No. The scope covers coordinating materials and correspondence between the coordinator and the specialist. Customs declarations and the release of the shipment stay outside it.

  • How much does an agent for customs documents cost?

    At Syntalith from €3,000 net. With 400 shipments a month at 15 minutes of coordination each, the payback is 1.0 month. We check access to the transport system and the documents before the quote.

  • When is the carrier's portal enough?

    When the sender completes the materials in one place and the coordinator sees the questions and answers there. DHL describes electronic document submission and file storage in paperless clearance.

Let's talk

Just write, call or choose a date.

We work fast because we hate corporate cotton wool. We don't have salespeople or managers to keep an eye on managers. You talk immediately to engineers who then build your system. We respect each other's time and yours too.

We will accept 3 more companies by the end of the year.
