Custom customer quality document portals

Short answer

A quality document portal shows the customer their delivery, the batch assigned to it and the approved document that covers it. A file with a similar product name is not enough: the batch and the current issue are what count. First check sharing in your current quality system or document library. At Syntalith the application costs from €3,000 net. At 300 document requests a month of 15 minutes each, it pays back in 1.3 months.

Statistics

Quality and documents: statistics 2026

1.3 mo.

payback of a €3,000 application at 300 document requests a month: €2,618 of work today, €263 with checking and the model. Scenario.

Figures checked: 22 October 2026

The document for this specific delivery

A customer asks for the quality certificate for a batch of material they received. A customer service employee finds a certificate in a folder for a product with a similar name, but with a different batch number, so they turn to the delivery record and keep searching. In the portal, the customer opens their delivery, sees the batch and downloads the approved document that covers it. A note that an earlier issue was replaced explains why the file differs from the one the customer has.

This view needs links in the data: someone names the delivery's batch and assigns to it a document approved for sharing. The quality department is responsible for the content and for approving a new issue, and the portal shares the named file with the right customer. When there is no approved document yet, the customer sees the gap and can ask a question.

What it costs and when it pays back

Scenario: 300 document requests a month
Today
300 document requests × 15 min = 75 h (€2,618)
With the system, a person checks the output in 10% of the time
€262
Model, 1 call per case, Claude Sonnet 5.5
€1
Cost of one case
€8.73 today, €0.88 with the system
Saving
€2,355 a month

Payback of €3,000

1.3 months

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: 1,500 input tokens and 200 output tokens per call at Anthropic's rates, at the ECB rate of 1.1205 USD per euro on 22 October 2026.

The count covers the work around a case: searching, reading, writing and handing over. What remains is the time to check the result, 10% of today's work in the scenario. Before the quote, we measure both times on 20 to 100 cases the team has already handled, in a free test that takes 5 working days.

The model is not the main part here. It helps match a customer's request from an email to a delivery, and most of the saving comes from linking the batch to the approved document.

First the library or your current quality system

If you use a quality management system, ask the vendor about sharing documents with customers and show them one delivery with a replaced document. With a simpler flow, an organised library is enough: Microsoft describes sharing in SharePoint with people outside the organisation, depending on the organisation's and the site's settings. A guest added as a site member can get edit rights, so you set the scope of permissions separately. A portal is justified when customer service regularly pieces together information from several places and the tools give no easy access to the documents for a specific delivery.

Library, QMS or a portal
  • Few customers, simple sharing

    a library with external access

  • The quality system can publish to customers

Where to start

The first scope can cover one type of document and the customers who ask most often. The test of the project is one question: does a signed-in customer find the right document for their delivery without contacting customer service. The flow of corrections and approvals is described in document workflow in quality control. We build this kind of rollout as part of AI applications. For the free analysis, a description of one case from recent weeks and of the tools it passed through is enough. You do not need to send confidential documents, and you get a written plan within 2 working days.

How we count the payback: quality documents

We run the same count for your customers in the free analysis.

€1,396

a month for handling 600 documents by hand

Payback: 2.5 mo.

4 minutes per document matched to a case 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. Model cost: reading a document in our case-file system (about €0.0002) plus matching it to the case and a note on what is missing (Claude Sonnet 5.5, about 2,000 + 300 tokens), at the ECB rate of 1.1205 USD per euro on 22 October 2026.

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

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

  • When is a quality document portal worth building?

    When customer service regularly pieces together the batch, the delivery and the approved document from several places, and neither the quality system nor the library gives customers easy access to the documents for a specific delivery.

  • What should the customer see when a document has been replaced?

    The current approved issue, with a note on which earlier issue it replaces. The history lets an employee answer a customer who is holding an older file.

  • How much does such an application cost?

    At Syntalith from €3,000 net. At 300 document requests a month of 15 minutes each, the payback is 1.3 months. We agree integrations and maintenance before the quote, and the model costs about €1 a month.

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.
