I needed an inventory accounting system for my business which was very specific to our industry (tires). We used SSI's software that did not have all of what we were looking fo so had it customized by another vendor who worked with us at no additional cost or time commitment from me as their client! It took about 10 weeks before they delivered everything requested but this is normal when you are working outside your core competency area in such specialized product development work - especially if there isn't much experience internally within said organization regarding implementation/customization like ours. The main benefit has been improved efficiency resulting directly into reduced overhead costs because less people required means more money saved per employee paid out each month.
