PIM system

Good day! I have collected and normalized product data from various sources (csv, xml, API) into a single database with auto-updating prices and stock levels, and exporting to the website and marketplaces. For millions of items, the main challenge is not the export itself, but how to consolidate different formats into one schema — that's where we should start. How many suppliers are there now and where should we prioritize exporting — to the website or eBay? I am ready to complete the initial working phase and then scale up.

Hello, Olga! This is Nina, the manager of the automation and backend development team.

A catalog with several million products is a serious architectural challenge. No Google Sheets or Excel will handle this; they will crash. A full-fledged ETL data pipeline and a high-performance database are needed.

What our Senior Developer Valentin will design and set up:
Central storage (DB): He will deploy a PostgreSQL database with proper indexing and batch processing to ensure the system can easily handle millions of products.
Flexible ingest and deduplication: He will write adapters for each of your suppliers (CSV, XML, API) to normalize the data into a single format and match products by SKUs to avoid duplicates.
AI enrichment of characteristics: He will integrate AI scripts that will automatically search for missing product parameters in open sources, parse them, and complete the product cards.
Multichannel export: He will set up auto-updating feeds for stock and prices to be exported to your website, eBay, and other marketplaces on a schedule.
…
Conditions: The specified budget of 10,000 UAH will be fully sufficient for the First working stage (4–5 days): Valentin will design a fault-tolerant database model, set up the import from the first supplier, and assemble a working prototype for stock updates. We will finalize the complete estimate for scaling the PIM turnkey after a brief discussion.

How many suppliers are planned at the start, and which marketplaces, besides eBay, are a priority for you? Let's communicate; Valentin is ready to discuss the formats of your feeds.

Hello! I will do PIM: ingesting supplier feeds (CSV/XML/API) → normalization and matching of products → enrichment of characteristics (including AI search in open sources) → a single table with auto-updating prices and stock levels. I work with catalogs of millions of items (Python + Postgres). The price is negotiable, I will clarify after the technical specifications.

Good day.

I have experience in developing systems with large volumes of data, integrations via API, and processing CSV/XML. I can propose the architecture of a PIM system with centralized storage of products, automatic updating of prices and stock levels, as well as export to the website and marketplaces.

Additionally, I can implement modules for enriching product attributes and automating data processing. I am ready to discuss data sources, volumes, and suggest an optimal solution.

Good day, Olga!

My name is Maxim Zashly. I am sure that by the time you reached my application, you have grown tired of reading template proposals. Therefore, without self-promotion, I will move straight to the question of creating your PIM system.

I understand that managing data for several million products from different suppliers requires a reliable solution. I am familiar with the complexities of data formats and the need to supplement them from other sources. My experience in databases and web programming will help create an effective system for your project.

I suggest discussing all the details in private messages or holding a meeting. I will share my vision for developing the PIM system, and if my approach interests you, we can discuss the next steps in more detail.

➡️ [Case 1](https://www.notion.so/Кейс-1)
…
➡️ [Case 2](https://www.notion.so/Кейс-2)

➡️ [Case 3](https://www.notion.so/Кейс-3)

For now, I will refrain from specific proposals. I believe that in development matters, we need to start from the ultimate goals of creating the PIM system. At this moment, unfortunately, there is no complete picture to provide specifics.

To better understand your vision and goals, and to propose the optimal option for our further cooperation, please clarify:
- What are the deadlines needed for launching the system?
- Do you already have a defined data structure, or does it need to be developed?
- Are you planning integration with specific marketplaces besides eBay?
- Do you already have a domain ready for data export?

These questions will help me better understand your needs and propose the most suitable solution.

The process, timelines, and cost of developing the PIM system can be influenced by the following factors:

1. The volume and format of data from suppliers, as well as the need for supplementation.
2. The availability of a ready database structure or the need to develop one.
3. The complexity of integration with various platforms, such as eBay and other marketplaces.
4. Whether you already have defined technical requirements or need to develop them together.
5. The number of features that need to be implemented for managing product data.

These aspects will help determine the scope of work and, accordingly, will affect the overall cost of the project.

Looking ahead, we will need to form a clear vision of the final result of the PIM system, which we will reflect in the technical assignment. I prefer to form such a vision based on competitor analysis and your personal wishes. This will allow us to understand how others solve similar tasks and make our system even better.

Hello! The task is clear: a PIM system with several million products, various formats from suppliers, and multichannel export. These are exactly the kinds of tasks I find interesting.

I have 3.5 years of commercial experience in fullstack development (TypeScript, NestJS, PostgreSQL, Vue/Nuxt). I have worked on B2B e-commerce platforms with large catalogs: ETL pipelines for importing from CSV/XML/API, normalization and deduplication of products, automatic price and stock updates, export in various formats for marketplaces. PostgreSQL with the right indexes and batch processing handles million-item catalogs well if this is built into the architecture from the start.

I am ready to start with the data model, adapters for your suppliers, and a prototype of the export. Please let me know how many suppliers there are at the start and where the export is needed first?

Good day. I understand the task: a PIM system for several million products. Data comes from several suppliers in different formats (csv, xml, API), often incomplete, so characteristics need to be filled in from other sources. Everything is stored in a single product table, regularly updated with current prices and stock levels, and exported to the website, eBay, and other marketplaces.

Essentially, this is a data pipeline around a central product repository. I see it like this: separate adapters for each supplier (csv, xml, API) with normalization into a single schema, an enrichment layer that pulls missing characteristics from additional sources and matches products by SKU or another key, regular incremental updates of prices and stock levels without full reloads, and separate exporters for each channel (website, eBay, other platforms) in their format.

With several million products, performance and correct matching are key to avoid creating duplicates during updates and to ensure that exports do not fail under load. PostgreSQL with the right indexes, batch processing, and queues, logging. This is built into the architecture from the start.

I take the budget of 10,000 as a starting point for the first working phase (data model, import of the first suppliers, updating prices and stock levels, export prototype), and then we scale. To estimate more accurately: how many suppliers are there at the start and where is the export needed first, to the website or to marketplaces?

Good day! I have experience in designing and developing systems for processing large catalogs. For your task, I propose a PIM with data import from CSV, XML, and API, normalization and merging of products from different suppliers, and automatic updating of prices and stock levels. We will foresee mechanisms for enriching attributes from external sources, storing millions of products, and exporting to the website, eBay, and marketplaces through separate feeds/API. I am ready to discuss the architecture and implementation stages.

Good day! I have experience with React/JS and integrations with CSV/XML/API. I will propose a PIM architecture: ETL/queues for import, normalization of attributes, a product table with price and stock updates, and exports to the website/eBay/marketplaces. We will start by discussing suppliers and data format, then MVP and scaling.

we already have a practically ready similar PIM architecture, it can be quickly adapted to your catalog, suppliers, and the first workflow ))
I am available, we can discuss the start right here on the marketplace.
with a budget of 10,000 UAH, it is not possible to create the entire PIM system for several million products, csv/xml/API, eBay, and other marketplaces.
it is rather a budget for a small technical start, not for a complete system.
We can start with a phase for 30,000 UAH over 10 days.
In this phase, I would include the data model, import of one or two suppliers, rules for updating prices and stock, a prototype for export, and a scaling plan.
Separately, we can add AI for searching and supplementing characteristics, but it is important to ensure quality control, as haste in the catalog can be more costly later.
First question - which marketplaces are needed after the website and eBay?
Second question - should the characteristics be supplemented completely automatically, or with manual confirmation before publication?

Hello.

The project is interesting. From the description, I see that this is not just a table, but a full-fledged PIM system: importing data from suppliers, normalizing products, updating prices and stock levels, enriching attributes, and exporting to the website, eBay, and marketplaces.

I would suggest starting with the technical phase: analyzing data sources, CSV/XML/API formats, category structure, attributes, update frequency, rules for merging duplicates, and export format.

After that, we can create an MVP:
— importing products from several suppliers;
— a unified product database;
… — updating prices and stock levels;
— error logging;
— basic attribute enrichment;
— exporting to the website/eBay in the required format.

For an accurate estimate, I need to see examples of supplier files, API documentation, the number of categories, and export requirements.

Good day!

The development of PIM systems is our specialized area (data, multi-sources, automation, export). The task is clear: with millions of products, this is not just a "table," but a full-fledged system, so we will lay the architecture correctly from the very start.

How we will implement it:

- Import from suppliers — connectors for each format (CSV / XML / API) with normalization into a single structure;
- Storage — PostgreSQL (Excel/Sheets will not handle millions), with indexes for fast search and filters;
- Price and stock updates — automatically on schedule from sources;
… - Data enrichment — searching for missing characteristics in external sources and supplementation (parsing + matching products by article / EAN / name);
- Export — to the website, eBay, and other marketplaces, according to the format and API of each channel.

To be honest: eBay and marketplaces have their own APIs and strict listing requirements — each channel is a separate job, and the enrichment of characteristics depends on the availability of articles/EAN for matching. We will take everything into account in the architecture.

The project is large, so we will manage it in stages: MVP (import + DB + price/stock updates + export to the website) → enrichment → eBay and marketplaces one by one. This way, you see the results at each step and control the budget.

We will discuss the price, timelines, and project details in personal messages.

Hello!

I have experience in developing systems for processing large product catalogs, integrations with suppliers via CSV/XML/API, and high-load systems using PostgreSQL, Python, and FastAPI.

For such a volume of data, it is important to separately work on the database architecture, processing queues, product deduplication mechanisms, search, and automatic completion of characteristics from external sources, as well as the requirements for marketplaces and the website.

I suggest discussing the project details, expected update volumes, and integrations in private messages.
