A spreadsheet works. Until there are five of them. A notebook works.
Until the number you need isn't in it. A simple cost calculator works.
Until material prices change, products get more complicated, and you're
selling in more than one place.
Spreadsheets start multiplying.
The information gets scattered.
Materials live in one place. Product costs live somewhere else.
Orders have their own system. Production might be tracked separately
again—or not tracked at all.
Eventually, running the business starts to mean keeping all of those
systems in sync.
Simple questions get harder to answer.
The business needs connected information.
How much does this product really cost? Do I have enough material
to make it? How many finished products are available? What did I
actually earn on those sales?
Those questions shouldn't require opening several files and
rebuilding the answer every time.
Traditional ERP is too much.
Small businesses need a better middle ground.
Enterprise systems can solve complex operational problems, but they
often bring enterprise terminology, setup, processes, and overhead
along with them.
Most small product businesses don't need all of that. They need the
right tools connected in the right way.
