This will depend on a few variables. If the branch office must have accurate inventory
levels at time of ordering, then iConnect is the best choice.
This may require dedicated lines depending on the order frequency, and depending on the number of people ordering simultaneously, a detailed analysis should happen regarding transaction volume, speed and efficiency. e.Advantage is also the better choice if you want branch offices to be able to access inter-company information such as reports, payroll, policies, sales analysis and the like. It depends of course on how central the head office information is.
If the branch office can use 'inventory levels as of this morning', then RemoteDesk offers a very inexpensive and more powerful alternative to on-line ordering. Not only does the branch site not require any accounting software, but RemoteDesk gives them the ability to order or invoice, send the details to head office and receive order confirmations and new stock levels, within a 1 minute e-mail transfer.
