Bottleneck 1: Steel Depletion & Restocking
Every single weld completed—whether done by your own hands or by hired AI employees—consumes physical steel plates from your shop rack.
- The Stalling Hazard: When your steel rack reaches 0, all production stops dead. Hired welders will idle, and the customer job board will gray out.
- Manual Hauling: Carrying crates from the truck to the rack takes valuable time away from the welding table.
- Auto Steel Pass (49 R$): This is widely considered the highest quality-of-life upgrade in the game. Delivery trucks automatically unload and stack steel directly onto your rack whenever inventory drops low.
Bottleneck 2: Hiring Welders vs Shop Capacity
When holding your first $10,000 to $50,000 in capital, prioritize shop workbenches before hiring extra staff:
| Upgrade Target | Primary Benefit | Prerequisite | Recommended Action |
|---|---|---|---|
| Workbench Upgrades | Unlocks higher tier job categories (Bikes, Pipes) | Basic shop level | Buy First: Directly increases manual cash payout per weld |
| Hired Welder #1 | Generates passive income over time | Stable steel supply | Buy Second: Ensure you have surplus steel before hiring |
| Auto Steel Delivery | Eliminates manual hauling trips | 49 Robux pass | Recommended: Keeps welders working 100% of the time |
| Cash Boost Pass (2x) | Multiplies all job and shop earnings | 99 Robux pass | Accelerate: Best ROI for active players |
If your hired welders ever stop working, check two things immediately:
- Is your steel rack empty?
- Is your customer order queue clear? Restock steel or accept fresh orders to restart their cycle.
Bottleneck 3: When to Fund Big Projects
Late-game engineering contracts—such as the Suspension Bridge and Space Rocket—require massive multi-stage capital commitments.
- Do Not Starve Your Working Capital: Never sink all your liquid funds into a project stage if it leaves you with less than $5,000 to purchase steel or workshop licenses.
- Stage Rewards: Large projects payout substantial milestone bonuses at completion stages, far eclipsing standard customer jobs.
