Accounting Firm
$111Qa base cost · $22.1B/sec
Business Overview
The numbers always add up.
Tier a industrial-stage staple, the Accounting Firm rewards players who buy it in bulk rather than one at a time.
Cost Scaling
Every business in Tycoon Cards uses the same cost curve: each copy costs 15% more than the last. For the Accounting Firm, that looks like this:
| Copies owned | Cost of next copy | Total spent to reach this many |
|---|---|---|
| 1 | $128Qa | $111Qa |
| 10 | $450Qa | $2.26Qi |
| 25 | $3.66Qi | $23.7Qi |
| 50 | $121Qi | $803Qi |
| 100 | $131Sx | $871Sx |
Income Scaling
Income scales linearly with copies owned — no diminishing returns, ever. Owning more of the Accounting Firm always earns proportionally more:
| Copies owned | Income per second |
|---|---|
| 1 | $22.1B/s |
| 10 | $221B/s |
| 25 | $552B/s |
| 50 | $1.10T/s |
| 100 | $2.21T/s |
Profit Calculations
| Payback period (1st copy) | 5,041,787 seconds |
| Income per dollar spent | $0.0/s per $1 |
| Efficient switch point | Around copy #4 (when the next copy costs more than Marketing Agency) |
See the Business Tier List for how this business ranks against all other 99 tiers by payback period.
Unlock Requirements
There is no gating system on businesses in Tycoon Cards — the Accounting Firm is available to purchase from the very start of any run, the moment you can afford its $111Qa base cost. The only realistic "requirement" is reaching that amount of money, either by clicking, by owning cheaper businesses, or by carrying prestige and card bonuses from a previous run.
Best Upgrades
Individual businesses don't have their own upgrade trees in Tycoon Cards — the Accounting Firm always earns exactly $22.1B per copy at base rate. What actually "upgrades" its value are the game's shared systems: levelling supporting cards (below), earning achievement bonuses, and increasing your prestige multiplier. Each of these applies as a percentage on top of every business you own, including this one.
Best Supporting Cards
At this tier, all-income and passive-income cards deliver the biggest absolute gains, since a percentage bonus on a high-earning business is worth far more in raw dollars than the same percentage on a cheap early tier.
Prestige Recommendations
Reaching this tier comfortably in a fresh run is a good sign your prestige multiplier and card bonuses are pulling their weight. If it takes a long time to get here after resetting, consider levelling more cards before your next prestige.

Research Interactions
Tycoon Cards does not currently include a research-tree system — the Accounting Firm cannot be researched or unlocked through any mechanic beyond simply affording it. A research tree is listed as a possible future system on our Updates & Roadmap page; this section will be updated if that ever changes.
