Price monitoring for marketplaces

What is included

• price tracking: add an item by article or by link, with no searching and no forms;
• an alert in Telegram when the price changes, with the old and the new price;
• stock levels per warehouse with an “almost out of stock” signal;
• a price change threshold in the settings: we react to what you marked as important, not to every tick;
• a daily morning summary: what changed over the day and what is running out;
• an alert if the marketplace stops answering — a silent monitor is worse than no monitor;
• change history and a chart for each item;
• a summary table with current prices for the whole list, exportable to Excel;
• 14 days of free bug fixes after launch.

What is not included

• the full set of Ozon fields is not pulled: what the platform exposes is what you get;
• price history from before the monitoring started: the service remembers only what it has seen;
• price forecasts, payback and restocking advice — that is a different job.
