It completely streamlines your business. The initial draw is to be online, but it's MUCH more than that. DecoNetwork provides you with a backend they call the Hub. From there you manage orders from all your stores, even if it just operate one. I operate 2 primary sites and a few smaller ones. It allows you to manage everything you need (off the top of my head): payment methods (credit cards, PayPal, direct wire, custom terms, N30, whatever you want), Statements, supplier product lines, EDI purchasing, customer discounts, customer store assignments, production management steps (purchasing, receiving, art approval, production, shipping), email notifications to customers for steps I mentioned, all history is recorded for you & customer to see (orders, quotes, notes, emails, confirmations, tracking, etc), private internal notes for order/quotes, customer statements, numerous notification options (payment requests, general emails, etc), customization of all system emails & order/quote/art approval templates, production operator assignments, multiple user rights (assign roles: admin, sales, accounting, production, art, etc), production overview (see all orders at a glance and all the status of each dept), Live shipping Methods (UPS, FedEx, USPS), custom shipping methods, complete supplier catalogs with correct data (skus, weights, costs - Alpha, SanMar, etc), Assign profit margin based on supplier cost, shipping based on true product weights, assign print areas to ALL products in single setting or individually, Smart Select rules automatically assign what decorating methods are allowed on products (think about one setting that removes DTG from all poly blends or buttons, numerous criteria), setup all your decorating price tables to be added to blank products (for each method, screen, dtg, embroidery, sublimation, transfer, rhinestone), customize color pallet & fonts avail for each method, customize product defaults (lets you change all settings for different set of products), product defaults can be overridden on individual products, abandoned cart retrieval (followup with email, convert to quote or order), quotes convert to order (by you or customer, easy check out.
Bottom line: even if you never get an online order, everything is managed through the cloud. You can enter an order knowing your product costs are accurate, with proper decorating price applied based on (qty, colors, stitches, etc), then click to email a quote or order, click to mark production steps complete, then click to email shipping tracking & invoice. If customers are not on terms they click to pay before order proceeds. It's awesome. Oh yeah, you can either batch or individually order the products from suppliers with the click of a button. Killer. One more thing, customer can place reorders (and modify them) and so can you from the Hub. Even start a new quote/order and access previous orders, layouts, etc)
As for websites, everything meshes with how you setup products etc. Customers can easily find their account area to view (order, quotes, art approvals, saved layouts, statements, payments, etc)
