In connection with the expansion of the assortment and the involvement of partners in the dropshipping system, we are looking for a specialist or team to create a modern online shoe store. An automated inventory management system is needed with the integration of partner Google Sheets. Main requirements: Responsive design for PCs, tablets, and smartphones. Product catalog with categories and filters (size, brand, color, price, etc.). Product page with photos, description, specifications, and size selection. Shopping cart and order processing. Integration of payment systems. Integration of delivery services. Customer personal account. Ability to add and edit products independently through the admin panel. SEO optimization of main pages. High website loading speed.Desired functionality: Wishlist. Automatic order status notifications. Integration of Google Analytics and Meta Pixel.Expectations from the performer: Examples of implemented online stores. Proposal regarding the platform (Shopify or another). Estimated cost and execution time. Further technical support after launch. Thus, the main feature of our store is that we work on a dropshipping basis and have several suppliers. It is critically important for us that the availability of products is synchronized between the suppliers' tables/files and the website, and that the stock is automatically updated according to current data. At the first stage, we need an online store with the following functionality: product catalog; product page; wishlist; cart; online payment; basic administration of products and orders. The user personal account is not a priority for now and can be implemented later. The most important part for us is the backend and the logic of working with products, stock, and data synchronization from suppliers. I would like to understand how you envision the implementation of such functionality in Shopify, OpenCart, or WordPress/WooCommerce, or other resources. Also, an important point: the website design is already almost ready, the frontend is in the form of an HTML mockup. Will you be able to work with the already prepared HTML version and integrate it into the chosen CMS, or will templates need to be redone? I would appreciate it if you could provide an approximate assessment: • Project execution time. • Implementation cost. • Which platform you would recommend for such a scenario and why. There will be more than 3 tables, these are the main ones as an example, generally similar in all templates; At the beginning, there will be up to 10, it is also important to have a process for adding new tables during operation; Do you consider Shopify, if not, then why? You can check the design and structure of the site at the link https://guileless-alpaca-8e86e5.netlify.app https://docs.google.com/spreadsheets/d/14GEA8a708YU7to9I6m7KWk8HaR1QP-7qN5fmx6pv-VQ/edit?gid=0#gid=0 https://docs.google.com/spreadsheets/d/1OMxsWn9jf6RYgKpiPI0E3Eif-Ykot5AmWlyQtAj0Cl0/edit?gid=0#gid=0 https://docs.google.com/spreadsheets/d/1tWyvhmomn8QFLR4BSMYERD3qtWlinSyBV6O0Nx3mxyA/edit?gid=0#gid=0 I also attach an example of a table for product export.

We are looking for a specialist in Allegro who has practical experience in launching and managing sales on the Polish marketplace. We need not just a consultation on "how Allegro works," but a person who can look at our situation, account, product, competitors, and explain how to properly launch to achieve the first sales. We have a product made to individual size. It is important that the specialist understands how to work with such products on Allegro: creating listings, photos, descriptions, size options, pricing, delivery, production times, and communication with customers. At the first stage, we need to: Check the Allegro business account. Say whether everything is ready for the start of sales. Analyze competitors in our niche. Suggest which products are better to launch first. Explain how to properly create a listing. Provide recommendations on photos, titles, and descriptions. Explain what price and delivery options are best to set. Advise whether promotion within Allegro is needed. Draft a simple launch plan for the first 7–14 days. It is important for us to understand the specific scenario: what we do, how long it takes, what budget is needed, and what results can realistically be expected. In your response, please include: — whether you have experience launching sales on Allegro; — what products you have worked with; — whether you can show cases or examples; — what is included in your consultation/audit; — what the cost is; — when you can conduct a short call.

It is necessary to set up exports on different sites. Make the price and availability correct. And the updates should be once every hour. Also interested in ongoing work.

First, it is necessary to edit 270 products on Khoroshop (the description column for marketplaces, where a table with characteristics needs to be inserted) and edit the modification names for the marketplace - 2700 names. After that, upload the feed to Rozetka and make sure everything works.
