Bank accounts and taxes

Our first payday

Picture Garden Defense's first month in the stores. AdMob says the studio has earned $112. AdMob pays out once earnings reach US$100, so Google is ready to pay. Where should the money go?

Not into anyone's personal account. It goes into a business bank account: an account in the company's name. Google Play, the App Store and AdMob all pay straight into it.

Opening the account

Once it is open, we enter its details in Google Play Console, App Store Connect and AdMob, so they know where to send our money.

Keep studio money separate

Quick check

Why does the studio get its own bank account?

  1. So studio money stays separate, the shield stays strong, and we can see what the games really earn
  2. Because banks only give accounts to companies
  3. So the studio can spend everyone's pocket money

So studio money stays separate, the shield stays strong, and we can see what the games really earn

A separate account keeps studio money apart from family and pocket money. It shows clearly what the games earn, and it keeps the company's shield strong.

Revenue, costs and profit

Three words every business uses:

Big revenue does not mean big profit. A studio can earn $10,000 and still lose money if it spends $12,000.

Bolt says: Some costs repeat and some don't. The Apple Developer Program is US$99 every year. Google Play registration is US$25, just once.

Profit check

REVENUE (money in)  Hyper Shards sales          $500  Garden Defense ads          $200COSTS (money out)  Apple Developer Program      $99  Google Play registration     $25  Domain name                  $12  Tools                        $64

Kai keeps the studio ledger: a list of all money in and out. Using these made-up numbers, what was the first year's profit?

  1. $700
  2. $500
  3. $200
  4. $900
Show the answer

$500

Revenue is $500 + $200 = $700. Costs are $99 + $25 + $12 + $64 = $200. Profit is revenue minus costs, so $700 minus $200 leaves $500.

Tax on profit

A tax is money paid to the government. It pays for things everyone uses, like roads, schools and hospitals.

In most countries a business pays income tax on its profit, not its revenue. So every real cost lowers the amount the tax is worked out on. Depending on the type of company, the company pays the tax itself, or the profit counts as the owners' income on their own tax returns. Many studios work with an accountant, a money expert who prepares the tax forms.

Keeping the books

Bookkeeping means writing down every bit of money in and out, with proof.

Quick check

Saving receipts can lower the studio's tax, because income tax is usually worked out on profit and receipts prove our costs.

Show the answer

True

Profit is revenue minus costs, and receipts prove the costs. Without them, the studio can't show what it really spent, and could end up paying tax on money it never kept.

Next: taking card payments

We have a company, a bank account and a way to track every dollar. Income tax is worked out on our profit once a year.

The stores and AdMob pay into this account for us. On our own website there is no store in between, so next we take card payments ourselves, with Stripe. Later in this stage comes a second kind of tax, one that touches every single sale before the money even reaches us: sales tax and VAT.

Bolt says: Up next: payments with Stripe. Then webhooks, currencies, and sales tax and VAT.
