#1 Additionally, what we noticed from the previous volume of changes: There are several clients who booked "Discovery Calls," but did not receive the invitation link from Calendly, just like us. Furthermore, the event did not appear in our MS Outlook calendar. This was set up initially. Can you fix this? The last two times we sent emails ourselves to provide clients with the meeting link. Please connect the MS Outlook calendars at sebastian leap-key.com and mj leap-key.com to Calendly. And send the confirmations for booked meetings to these same email addresses. #2 Another similar issue concerns invoices from WIX. I see on WIX that the last invoice has number 5, but there should be two more: #6 and #7. WIX was set up to create an invoice and send it to the client's email address and to our email address (sebastian leap-key.com), but this is not happening. It is important that both clients and we receive invoices directly. Exceptions will be those products with individual prices, for which we will use WIX to generate invoices. - The prices for product #4 are set individually, so I need to issue invoices for them. Products #1, 2, 3 have fixed prices, and invoices for them can be generated automatically. - I tried to go through the entire process by booking a meeting for products #1, 2, 3 from my personal email address svuinovich gmail.com, but I did not receive an invoice. It seems I received an email with confirmation of the booked meeting. I don't remember now. - Confirmation and invoice should be sent to the client, as well as to the addresses sebastian leap-key.com and mj leap-key.com. Invoices were not sent to either Sebastian or MJ from Leap Key, nor to me as a client at my personal email address.

I need an online casino, a website or a Telegram app, it doesn't matter what options are available, please suggest. I only work through the website and without prepayments, prices up to $1000.

A separate CRM system needs to be developed for the centralized processing of all retail orders from various sales channels (Prom, Rozetka, own websites, and manual orders). Main requirements: A unified order registry from all sources, preserving information about the source and its status. A separate internal CRM status that operates independently of the status on the marketplace or website, with two-way synchronization of statuses where supported. Flexible integration with 1C: for each source, the administrator can separately enable or disable automatic order export. Integration with carriers for automatic creation of shipping documents, saving their numbers in the CRM, and transmitting the shipping document numbers to Prom and Rozetka. Integration with Checkbox for creating receipt projects, using customizable payment method matching, with subsequent fiscalization control. Support for manual order creation (phone, Viber, Telegram, Direct, etc.) with a complete subsequent processing cycle through the CRM. All API keys and integration settings must be managed by the administrator through the CRM interface without the involvement of a programmer. A complete action log and integration logging for system operation control. Main goal The manager must be able to fully process orders in one CRM interface — from receiving the order to creating a document in 1C, shipping document, receipt project, and completing the order, without the need to access the cabinets of Prom, Rozetka, websites, carriers, or Checkbox.
