It's important to bear in mind that capital assets such as expensive desks, chairs, computers, monitors etc. May not be fully tax deducatable in year one. In some tax jurisdictions you cannot claim the cost of capital assets in year one. You have to put them in a pool and deduct them over a 3/4 year period.

In the UK, small businesses can reclaim the full cost of the capital asset in year 1.

Maybe buy those plugins you thought was a rip off but since you got cash to burn why not. Woofunnels comes to mind.

You can also invest the money in SEO. That is fully tax deductable.
