Corporate ecommerce website for the sale of industrial supplies business to business

Measurement Solutions is in the VERY BEGINING stages of review options for either recreating our current website from scratch using a different plateform OR completely reformating our current website in Magento 2.4.6 We have been on this current website plateforn for about 6 years now and have had numerious developer touching it and now we are running into errors. there are 3 keys factors to this project. 1.) we want to use the products that are currently entered into the website - we do not want to re-enter anything 2.) our current catalog count is about 6000 SKU's which we want to grow to over 50,000 SKU's so the website MUST handle this 3.) we use ZOHO for our ERP system so the new/revamped website must drop orders directly into ZOHO.
