Our server bills are in EURO.
Our salaries are in EURO.
Our subscription for business operations are in EURO.
Our accountancy costs are in EURO.
It helps that our focus is on European customers, but that said, it is hard to justify going with USD pricing.
Is it painful in terms of accounting? Yes. Do I lose money on conversion rates? Yes. Am I making more money? Yes.
Unless you exclusively target a particular market, most people in US might not even know what EUR is. For them it might be the same as Zimbabwean dollars to you.
Depending on where your vendors are situated, you might avoid the conversion losses by having USD accounts AND EUR accounts.
We use two separate banks (for redundancy), each of which allows us to have incoming payments in EUR, USD, and a couple of lesser currencies (CAD, SGD) and we keep a balance in each.
And then we use the USD balance to pay, eg. DigitalOcean, and the EUR balance to pay eg BunnyCDN. So we mostly don't have to incur the conversion loss.
Your tactic over paying with USD revenue for USD bills is a good tactic.
Our policy is to avoid US vendors and USD subscriptions.
