 Если чек создан в ФНС, но письмо клиенту не отправилось, API вернет `success: true`, `receiptCreated: true`, `emailSent: false`, `receiptId`, `printLink` и `technicalError`. Ошибка отправки сохранится в `error.json`.
 
 Все успешно созданные чеки сохраняются в Redis, чтобы в UI была связь между чеком, email пользователя и позициями заказа. Синхронизация с ФНС выполняется за выбранный месяц, подтягивает страницы по 50 записей до конца месяца и помечает аннулированные чеки как `cancelled`. Аннулированные чеки показываются в списке, но не учитываются в количестве действующих чеков и итоговой сумме.
+
+В UI и API по каждому чеку рассчитываются суммы `grossAmount` (грязными), `taxAmount` (налог) и `netAmount` (чистыми). Для физлиц используется ставка 4%, для юрлиц 6%.
