As a hardware manufacturer ourselves we feel your pain.
We made the mistake of using anodized aluminium for the front panel of our units. Then it turned out that the current batch of Aluminium our suppliers were using was trash and couldn't be anodized. That took weeks and weeks to design a workaround for and get quotes and stock in. In the end we had to pay for junk aluminium that we threw in the bin.
Then we had an aerial manufacturer who kept shipping us different aerials every time we ordered the same part, which never matched the sample.
Next we discover that the manufacturer who provides our plastic cases had taken a plastic with a certain safety rating but didn't take into account that the dye that they also added changed that rating and prevented us from using the cases. We were in a shed filled with noxious smoke trying to burn cases (which shouldn't burn) over several batches to get that sorted.
And finally we have a RF system that some customers try to use in a faraday cage and of course it's pretty hard to get working. For example installations in industrial coldstores.

Of course effort and time solves these issues but wouldn't it be nice to just have to ship bytes.
