Invoices

Every paid event — order, subscription renewal, top-up — produces an invoice. Find them under Billing → Invoices.

Filter by period or status (paid, due, failed).

Tax

We apply tax based on:

• US — by ship-to state, where helodata has nexus (currently CA, NY, WA)
• EU — VAT at the rate of your billing country; if you supply a valid VAT ID, we reverse-charge (no VAT on invoice)
• UK — VAT 20%; reverse-charge with a valid VAT number
• Canada — GST/HST per province
• Everywhere else — no tax at source; you may owe local taxes

Update your Tax ID under Billing → Address & tax so it appears on invoices.

Currency conversion

If your default currency is EUR or GBP but your card was charged in USD, the conversion rate appears on the invoice with the date applied. Your bank may apply a separate FX fee — that's between you and the bank.

Custom invoice formatting

Enterprise plans can request:

• Custom logo on invoices
• A different "Bill to" entity (e.g. parent company vs subsidiary)
• Net 30 / Net 60 payment terms (instead of pay-on-issue)
• PO numbers on every invoice
• Multi-entity rollups (one master invoice per quarter)

Email [e-mail].

Disputes

If an invoice looks wrong:

1. Open it from Billing → Invoices.
2. Click Dispute.
3. Pick a reason and describe what's wrong.
4. Our billing team responds within 2 business days. If your dispute is valid, we issue a credit note that offsets the next invoice.

Common pitfalls

• VAT charged when you have a VAT ID — your VAT ID wasn't validated. Check Billing → Address & tax for the green checkmark; otherwise re-enter or contact [e-mail].
• Tax appears on a US invoice but you're not in those states — check your shipping/billing state in Address & tax.
• Old invoices missing — invoices are retained for 7 years; export periodically for your own retention if you need longer.
