B2B returns: what was agreed and what arrived?

Short answer

A shared B2B returns view sets the agreed items beside what the warehouse actually received, so customer service asks about a specific difference and does not have to call for details. First check whether your current system supports partial receipt and whether customer service can see the warehouse record. At Syntalith the application costs from €3,000 net. At 300 returns a month of 20 minutes each, it pays back in 1.0 month.

B2B trade and returns: statistics 2026

1.0 mo.

payback of a €3,000 application at 300 returns a month: €3,490 of work today, €526 with checking and the model. Scenario.

Figures checked: 22 October 2026

Six units in the parcel, four that match the agreement

A wholesaler agreed with a customer on the return of six adapters with a specific code. The warehouse worker finds four such adapters in the parcel and two units of a different product. The total number of units matches, but the contents do not. The warehouse worker records what actually arrived: four adapters against the agreed line, two missing units and two other products to clarify separately.

In the proposed view, a customer service employee opens the agreement and the warehouse record side by side, and if the company shares photos from receipt, they see the attachment too. They have a basis for a specific question: the parcel held four of the agreed adapters and two other products. The customer's answer stays with the same return, and the original agreement is not overwritten when the parties change it.

What to keep when the tool changes
  • Open returns with their agreed lines
  • Receipt records with their differences, because a bare „six units received” loses the gaps
  • The correspondence and the questions to the customer
  • Earlier agreements, when they change

What it costs and when it pays back

Scenario: 300 returns a month
Today
300 returns × 20 min = 100 h (€3,490)
With the system, a person checks the output in 15% of the time

Cost of one case

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: 2,000 input tokens and 300 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, 15% 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 an extra here: it helps match the customer's description from an email to a line in the agreement. Most of the saving comes from one case number running from the agreement to the receipt.

Your current system may already handle partial receipt

Sales and warehouse systems often support return orders linked to sales lines, partial receipts and splitting lines. Work out with the administrator where customer service will see the actual quantities and differences the warehouse recorded: if the data is available, configuring a view or switching on a module is enough. An integration helps when each system handles its own part well, but data is not passed between the request portal, the agreement and the receipt. Your own view is justified when, despite the modules, customer service still retypes agreements and asks the warehouse for separate explanations.

  • Customer service still retypes and asks the warehouse

    a shared returns view, one warehouse to start

    €3,000–€7,000

Where to start

The first scope can be limited to one warehouse and the recurring differences in parcel contents. After launch, someone has to react when the warehouse records a receipt that customer service cannot see. The wider scope for wholesalers is described in AI in wholesale. 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: returns in a wholesale business

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

€5,584

a month for retyping 1,200 orders by hand

Payback: 0.6 mo.

8 minutes to retype an order 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.

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:

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.

Custom AI apps

When an off-the-shelf tool does not fit, we build your own.

We build an application with a language model for the work of your team: searching the company's knowledge, case panel or portal. We check the validity of your documents before launch, and the code stays with you.

Questions

  • How do you handle B2B returns when the parcel differs?

    The warehouse records the actual contents of the parcel, and customer service sees them beside the agreement with the customer. The differences, meaning missing units and other products, are separate items to clarify.

  • Do B2B returns need a new system?

    Usually not at the start. Check partial receipts in your current system and the view for customer service. Your own view makes sense when, despite the modules, customer service still retypes the agreements.

  • How much does such an application cost?

    At Syntalith from €3,000 net. At 300 returns a month of 20 minutes each, the payback is 1.0 month. We agree integrations and maintenance before the quote, and the model costs about €2 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.
