Sell Lemons Income Sources Guide
All 8 income sources explained — when to unlock, how to upgrade, which Manager to hire, and upgrade priority for each tier.
Tier 1: Lemon Stand
Unlocks: Available from the start
The foundation of your lemon empire. Click the stand to earn cash, then upgrade it with the Juicer, Cup Stand, and Sugar Mixer. Once automated, the Lemon Stand runs passively.
Tips
- →Get the Juicer upgrade first — it doubles your stand income immediately
- →Hire the Stand Automator as soon as you can afford it
- →The stand scales well with global cash multipliers from rebirths and ascensions
Upgrade Priority
High early, then maintain proportionally
Tier 2: LemonDash Delivery
Unlocks: Unlocks after Lemon Stand + basic upgrades
A racing/delivery minigame that produces burst income per run (~$16K–$17K per 15 sec early). The LemonDash Manager fully automates delivery runs, making this an A-tier passive income source.
Tips
- →The Vehicle Speed upgrades meaningfully boost delivery income
- →Once managed, LemonDash requires no active input
- →Strong during early and mid-game before Lemon Depot takes over
Upgrade Priority
Medium — upgrade Vehicle Speed, then let Manager handle it
Tier 3: Lemon Depot
Unlocks: Unlocks after Lemon Stand + LemonDash
Wholesale bulk truck operation — the first income source to break millions/second. The Depot Manager costs approximately 14 trillion cash but automates the entire operation.
Tips
- →This is your primary income driver for most of mid-game
- →During Void Weather events, focus ALL upgrades on Lemon Depot
- →The 4× speed upgrade (~20 billion cash) is a major power spike worth prioritizing
Upgrade Priority
Very high — max Depot speed upgrades as your priority during mid-game
Tier 4: Lemon Trading
Unlocks: Unlocks after 14/16 investments across Stand + Dash + Depot. Alien Joe arrives to grant access.
A stock market minigame with high risk/reward. The alien named Joe appears when you have made enough investments — click him to unlock trading. The Trading Manager automates trading decisions.
Tips
- →Do not try to "time" the market manually — it is RNG-based
- →Hire the Trading Manager quickly to automate this source
- →Useful income supplement but not a primary driver — do not neglect other sources for it
Upgrade Priority
Low — hire Manager and let it run passively
Tier 5: Lemon Labs
Unlocks: Unlocks in late mid-game after previous tiers are established
Research facility that provides permanent upgrade scaling. Less immediately efficient than Rebirth stacking but valuable for long-term multiplier depth.
Tips
- →Lemon Labs upgrades are permanent — they compound with every rebirth reset
- →Prioritize Labs upgrades that boost global speed or cash generation
- →The Labs Manager handles automation once hired
Upgrade Priority
Medium — steady investment after core income sources are running
Tier 6: Lemon Robotics
Unlocks: Unlocks in advanced late-game progression
Automation-focused income source with further multiplier scaling. Builds on the foundation of Labs and previous income tiers.
Tips
- →Focus on global cash multiplier upgrades within Robotics
- →Hire the Robotics Manager immediately upon unlocking
- →Do not skip earlier income source upgrades to rush Robotics — the compounding effect requires a strong foundation
Upgrade Priority
Medium — consistent upgrades once unlocked
Tier 7: Lemon Republic
Unlocks: Unlocks in deep late-game after Lemon Robotics is established
Global multiplier operation that amplifies all previous income sources. The Republic represents the penultimate tier before the endgame space station.
Tips
- →Republic upgrades that multiply all income are highest priority
- →This tier compounds exceptionally well with high rebirth stacks
- →Hire Republic Manager immediately — passive income compounds fast at this stage
Upgrade Priority
High once unlocked — Republic multipliers amplify your entire empire
Tier 8: LemonX
Unlocks: Final income tier — endgame space station. Unlocks after completing all previous tiers.
Extraterrestrial space station that represents the pinnacle of your lemon empire. Has very slow base production speed — do not unlock until global speed upgrades are maxed.
Tips
- →Critical warning: LemonX has very slow production speed by default
- →Get global speed upgrades maxed BEFORE unlocking LemonX or it will bottleneck your empire
- →Once speed is sufficient, LemonX produces enormous cash that makes all previous tiers look small
Upgrade Priority
Extreme caution — unlock only when speed upgrades are fully maxed
