# Set your billing details — and the three fields people get wrong

Your billing details drive your invoices and, in some cases, how you're taxed. Filling them in once, correctly, saves a round of corrections later.

## Where to find them

**Account → Profile**, then scroll down to the billing section.

> If you have a default shipping address, you can fill that in on the same page.

## The fields

**Legal company name**
Fill in your **legal** company name if you have a company. Leave it blank if you don't.

> ⚠️ **Don't put your brand name here.** This field goes on the invoice, so it has to match your company registration exactly. Your brand name belongs in "Configure your POD brand."

**Company registration number**
Numbers only.

> Even if you don't have a valid VIES or VAT number, fill this in — we'll tax you accordingly. See "I'm not paying VAT but it's mandatory to fill my country code."

**Postcode**
Fill in your real postcode.

> ⚠️ **Avoid filling six zeros.** A placeholder postcode breaks invoicing and, for Romanian companies, can block the electronic invoice from being accepted.

**Phone**
Required — we need a way to reach you if something goes wrong with an order or a delivery.

## Save

Click **Save Changes**. Done.
