Some options will have transaction limits that you may wish to consider. But we also have other solutions where this is not a consideration. The difference in this area will be appetite for cost and an understanding of when a solution may no longer be appropriate in line with growth plans. Either way, we will always recommend solutions that optimise a system. We can use data aggregators to ensure transactions are posted in the leanest way to elongate the useful life of any system, so you won't have to upgrade until it is absolutely necessary.
