Update Magento on a virtual server under Ubuntu

I need help figuring out how to connect Viber so that the business owner can track the conversations of the managers. I have an online spare parts store. I previously worked alone. In the spare parts field, people often write specifically in Viber. I have a large client base that writes in Viber. I need to come up with a way for clients to write to a familiar account while the manager responds. Starting next month, I plan to hire a sales manager, and I need help connecting Viber to some platform where I could track conversations with clients.

It is necessary to transition from the old program 1C "Pharmacy for Ukraine" to BAS with a complete data transfer and launch of the new system into operation. Tasks — analyze the current database of 1C "Pharmacy for Ukraine"; — select and justify the BAS configuration suitable for retail trade, warehouse, procurement, sales, mutual settlements, and financial accounting; — install BAS on work computers or server; — configure users, access rights, stores, warehouses, cash registers, and organizations; — transfer data from the old 1C to BAS; — check the correctness of the transferred data; — configure trading equipment and external services; — conduct a test launch; — eliminate errors identified during testing; — prepare the system for full operation. Data to be transferred — product nomenclature; — categories and groups of products; — barcodes; — purchase and retail prices; — stock balances by warehouses and stores; — contractors; — suppliers; — mutual settlements; — debts and overpayments; — procurement and sales documents; — if possible — the history of product movements and sales. Before starting the transfer, the executor must check the database and inform in writing which data can be transferred completely, partially, or cannot be transferred. Necessary settings — loading bank statements; — working with client-bank; — integration with Checkbox; — configuring cash registers and fiscal receipts; — barcode scanners; — receipt printers; — printing price tags and labels; — product returns; — transfers between stores and warehouses; — inventory; — purchases, sales, and write-offs; — operation of multiple users. Updates and modifications The configuration must have the capability for further updates. All modifications must be made so that they do not disappear after updating BAS. Before making changes, the executor must agree on the implementation method: configuration extension, external processing, or another safe method. Unilateral removal of the configuration from support without agreement is not allowed. Work results — BAS installed and activated; — data from the old 1C transferred; — balances and mutual settlements reconciled; — Checkbox, bank, and trading equipment operational; — procurement, sales, returns, transfers, and inventory can be processed; — receipts, price tags, and labels can be printed; — a backup of the working database created; — a brief instruction on backup and updates provided; — training for responsible employees conducted. The response must indicate — recommended BAS configuration; — experience in transitioning from 1C to BAS; — experience in data transfer from industry configurations; — experience in integration with Checkbox; — method of preserving modifications after updates; — cost of each stage; — execution time; — cost of further support. Payment is preferably staged: database audit, installation, transfer, configuration, testing, and launch.
