Three things, not one
Worth saying plainly, because "we are rebuilding it" sounds like one job and it is three, each of which has to work before any of it is worth selling.
- A website — scantracksystems.com.au, live, and saying page by page which parts work today
- A portal, hosted and managed by us in Sydney
- A scanner app, tested in a real aisle on real hardware rather than on a desk
And the part that is not code at all: knowing how warehouse people actually work, and which barcode scanner belongs in which hand. Thirty-five years of fitting that equipment is the reason this is worth attempting at all, and it is still the slowest part of the job.
Time, money and a long attention span. There is no shortcut version of this and we are not pretending there is one.
