I need to ensure that I don't lose my balances and legacy data during my switch to Everest
Everest comes with wizard-driven data import utilities that not only import balances for customers and vendors, but also allow lookup of invoices so you can migrate fast without having to toggle between systems that contain old data and those that hold new data.

My staff has to re-key orders that originate from my Yahoo! Store, and match credit card information collected
Via its sales order import functionality, Everest eliminates the extra time involved in re-keying of data. This allows your staff to import orders from existing customers, create new orders on-the-fly as they are generated, and even batch process credit card information, saving your business time and money, and ensuring accuracy.

Integrating with third-party catalogs has been painfully slow for my business, and never yielded information that was up-to-date
Everest's Third Party Catalogs can include products from many different vendors by allowing the import of catalog details from text files and Excel spreadsheets. This allows you to grow your revenues by increasing your product offering to customers, confident all the time that with Everest's powerful, seamless capabilities in the backend, your staff will be in a position to handle the extra load right from taking and processing orders to managing drop shipment of ordered items.

I cannot update quantity and prices on an on-going basis for my business' third-party catalogs
Everest lets you update items, prices and stock status pertaining to third-party catalogs, and also add new items as and when they are introduced in those catalogs. This means your new items information is quickly seen by your customers for a quicker turnaround on that stock, and hence accelerated sales growth.
