Business License

Business License is an economy upgrade that grants a permanent fifteen percent discount on all purchases made at the Mart. Every upgrade, item, and service in the shop costs less when you have this upgrade equipped, stretching your Sheckles further and allowing you to purchase more or better upgrades over the course of a run.

How It Works

The Business License applies a flat fifteen percent reduction to the listed price of every item in the Mart. The discount is calculated automatically at the time of purchase — you simply see the reduced price displayed next to each item. There is no special action required to activate the discount, and it applies to every Mart you visit during the run.

The percentage-based discount scales with the cost of items. On cheap upgrades, the Sheckles saved per purchase are small. On expensive S-tier upgrades like Helmet, the savings can be substantial — potentially the difference between affording an upgrade immediately or needing to wait for another room of income. Over a full run with multiple Mart visits, the cumulative savings from Business License can easily exceed the cost of the upgrade itself.

Cost and Availability

Business License is priced in the low-to-moderate Sheckles range. It appears with average frequency in Mart rotations and is typically purchased by economy-focused players who plan their build around maximizing purchasing power. The upgrade effectively pays for itself after two to three discounted purchases, making it a sound investment over longer runs.

Tier Ranking: C

Business License earns a C-tier ranking because while the discount is always useful, the savings are incremental rather than transformative. A fifteen percent discount helps, but it does not unlock upgrades you could not otherwise afford — it merely accelerates the timeline by a small amount. In the early game when items are cheap, the discount is barely noticeable. In the late game when you are saving for a single expensive upgrade, the savings become meaningful but still not game-changing on their own.

Best Synergies

• Paycheck: More passive income means more Mart visits with more Sheckles to spend, and each purchase is discounted. The two economy upgrades reinforce each other.
• Medal: Higher end-of-run rewards plus cheaper purchases in the next run create a compounding economic advantage over multiple runs.
• Gift Magnet: More collectibles gathered means more Sheckles available at the Mart, and Business License ensures those Sheckles go further.
• Helmet: The most expensive upgrade in the game benefits the most from a fifteen percent discount, making Business License an excellent companion purchase when saving for Helmet.

Tips

Buy Business License early in a run if you plan to make multiple Mart visits. The sooner you have it, the more purchases benefit from the discount. If you are doing a short run or expect to visit the Mart only once, the savings may not justify the slot.

FAQ

What does Business License do in Nullscape?

It's an economy upgrade that permanently applies a 15% discount to everything in the Mart — every upgrade, item, and service, at every Mart you visit for the rest of the run. The reduced price shows directly on each item; no activation needed.

Is Business License worth it?

Over a multi-visit run, yes — it effectively pays for itself after two or three discounted purchases, and the savings on expensive S-tier items (like Helmet) can be the difference between affording one now or waiting another room. For short runs or single Mart visits, skip it.

What is Business License's tier ranking?

C-tier. The discount is always useful but incremental: it accelerates your purchasing timeline rather than unlocking anything you couldn't otherwise afford. Economy-focused players value it; damage-focused builds usually spend the slot elsewhere.

What synergizes with Business License?

Paycheck (more passive income plus cheaper purchases reinforce each other), Medal (end-of-run rewards compound with cheaper next-run shopping), Gift Magnet (more collectibles means more Sheckles for the discount to stretch), and Helmet — the most expensive upgrade in the game benefits most from a 15% cut.

When should I buy Business License?

Early, if you're planning multiple Mart visits — every purchase after it benefits. Late-game purchases save the most Sheckles per transaction, but you only get those savings if you still have shopping left to do.
