Why an eBay payout differs from your order total

Short answer

Marketplace settlement automation lines up a payout with fund movements, fees, refunds to buyers and the shop's orders, shows the source of a difference and the amount that cannot be assigned yet. Bookkeeping and tax assessment stay outside the scope. At Syntalith the automation costs from €3,000 net, and with 40 marketplace payouts a month at 60 minutes each it pays back in 3.1 months.

Statistics

E-commerce and AI: statistics 2026

3.1 mo.

payback of a €3,000 automation at 40 marketplace payouts a month: €1,396 of work today, €422 with checking and the model. Scenario.

Figures checked: 22 October 2026

Marketplace settlements: a combined charge and detailed fees are different records

The person settling sales on Allegro, the Polish marketplace, wants to explain a payout. In the funds statement they see a combined charge for fees, refunds to buyers and income from orders, and the total does not match the shop's order register. The difference between the totals alone does not say whether a transaction is missing or a fee belongs to another period. Allegro explains how it collects fees (in Polish) for its services from the money from sales.

The view lets you open the payout, the fund movements and the fee history next to the shop's orders. The sale date, the date of the fund movement and the payout date can fall in different periods, and a refund to the buyer and a refund of the seller's fee carry separate labels. Once the recognised parts are joined, what remains is a line that cannot be assigned, with its amount and source.

Rules for lining up a payout
  • Amounts and currencies from the source materials, with no default conversion
  • Each line showing the statement it comes from
  • A refund to the buyer and a fee refund as separate lines
  • An unassigned amount kept visible for clarification

With orderly transaction and order numbers, rules do the matching and the calculations. AI helps read inconsistent descriptions of movements and match them to orders when the number is not given directly.

What marketplace settlement automation costs and when it pays back

Scenario: 40 marketplace payouts a month
Today
40 marketplace payouts × 60 min = 40 h (€1,396)
With the system, a person checks the output in 30% of the time
€419
Model, 2 calls per case, Claude Sonnet 5.5
€3
Cost of one case
€34.90 today, €10.55 with the system
Saving
€974 a month

Payback of €3,000

3.1 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: 15,000 input tokens and 1,200 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026.

The count covers the work around each case: searching, reading, writing and handing over. What remains is the time to check the result, 30% 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.

An unexplained difference in a payout often stays until the end of the year as one amount to correct. When every payout has its parts assigned each month, accounting gets closed summaries, and questions to the marketplace can be asked while the data is fresh.

Check the marketplace reports before integrating

If the marketplace's report already lets you explain a payout, it is enough to organise how you use it and link it to the shop's order numbers. An automation makes sense when the shop sells on several marketplaces, there are dozens of payouts, and an employee moves between statements in a spreadsheet every month.

Where to start

We base the first call on one payout where the employee spent a long time moving between statements, for a chosen account and period. We build this kind of system as part of our AI automations. For the free process review, a description of one case from the last few weeks and the tools it went through is enough. You do not need to send confidential documents, and you receive a written plan within 2 working days.

How we count the payback: AI in e-commerce

We run the same count for your marketplaces in the free process review.

€2,792

a month for handling 800 orders that bypass the checkout

Payback: 1.3 mo.

6 minutes to retype an order or answer a question 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 the order in our system (about €0.0006) plus matching the lines (Claude Sonnet 5.5, about 3,000 + 500 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.

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:

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.

AI automations

This process can go on its own. You will check this on your cases before you pay.

The system takes over repetitive work from emails, documents and spreadsheets, and hands over uncertain matters to a human. A prototype for 20-100 cases that your team has already handled costs €0. You pay the other half of the price when the system reaches your goal.

Questions

  • Why does an Allegro payout not match the order total?

    Because the payout reflects service fees collected, refunds to buyers and movements from other periods. Lining up fund movements, fees and orders shows the source of the difference.

  • Does the automation book the settlement?

    No. It prepares a summary for the team to review. How the settlement is booked and the tax assessment stay in the accounting process.

  • How much does such an automation cost?

    At Syntalith from €3,000 net. With 40 marketplace payouts a month at 60 minutes each, the payback is 3.1 months. We agree integrations and maintenance before the quote, and the model costs €3 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.
