Quikcell would still find a way to screw it up. Accidentally label several of the LRM launchers as belonging to the SRM Carrier, get the part numbers swapped for the Pike and the Demolisher so they have each other's autocannons, or just never label the SRM ammo container as fragile/explosive so your cook crew has been using that container to support the BBQ grill.
Overall, as long as you order enough of their products you are statistically likely to get the vehicles you ordered. The fun part is tracking down all the necessary pieces in the process, requiring more admin skills than technical skills.
For RPG-wise, it would mean you need more of a technical staff on-hand as you are having to assemble the vehicles, rather than receiving them (mostly) put together. On the bright side, the usual assembly defects don't show up since it is your personnel putting the equipment together. Your tech teams can even make sure that the units with bad equipment are fully demanded a refund for, while swapping the parts around to make as many vehicles as possible. I.e. you order twelve Scorpions as pieces, and 9 of them have separate flaws that would make the unusable. So you file a claim to QuikCell for discounts/replacements for all nine of those Scorpions, while your techs are swapping parts around so you have eleven Scorpions that work and one Scorpion that has nearly everything wrong with it.
Still, hope your tech teams have the correct instruction guides as it would be a shame if they were using the guide for the Scorpion-1S and and you received the parts for the Scorpion-I5
