My purchase-approval flow is the same for $1 purchases as it is for $1k purchases. If we hadn't finagled a minor workaround, it would be the same as that required for $5k purchases.
Handling each purchase and documenting it in case we are ever audited requires easily $25-50 of people's time.
Or has toxic micromanaged structure. I've had friends who have worked places that would barf over ongoing $60/year software charges, where anything like that would have to go up to C levels and require justification. Luckily never worked at one myself, dodged that particular bullet.
