01Getting started#

An account takes about ten minutes to set up and does not require a card. The steps below are the same for every plan.

1. Create the account with your business email. Confirm the message that arrives within a minute.
2. Fill in your business identity — legal name, tax identifier, address — and upload a logo if you have one. This is what appears on every invoice.
3. Set your numbering: prefix, starting number, reset cadence. Changing it later is possible but existing invoices keep their numbers.
4. Connect a shop platform, or import your customer list from CSV.
5. Issue a test invoice to yourself. Check the email, the PDF and the download link before you invoice a real customer.

02Connecting a shop#

Shopify, WooCommerce, PrestaShop, Etsy and Wix connect in one click from Settings → Integrations; you are sent to the platform, approve the access, and come back to a connected state. Anything else goes through the REST API or a scheduled CSV import.

03Invoices and numbering#

Each invoice gets a permanent number at issue and cannot be renumbered. To correct an issued invoice, issue a credit note and a replacement — that is also what a tax auditor expects to see.

• Currencies: an invoice is issued in one currency. Multi-currency customers need one invoice per currency.
• Tax: set a rate per line or per invoice. For Indonesian customers, enter your NPWP so the faktur pajak carries it.
• Attachments: one PDF up to 10 MB per invoice, stored encrypted and served through the same signed link.
• Voiding: an invoice can be voided before delivery. After delivery, use a credit note.

04Delivery and reminders#

Invoices are delivered by email with a personal link that expires after 7 days. If a customer loses the link, resend from the invoice page — the old link stops working and a fresh one is issued.

Reminders are scheduled at 7, 14 and 30 days past the due date. Each one re-checks the invoice before sending, so a payment that lands in the meantime cancels it. If a customer says they never received anything, check the delivery log first: it distinguishes sent, delivered, opened and bounced, and a bounce almost always means the address is wrong rather than the mail being filtered.

Mail delivery add-on

Mail delivery is the sending layer under invoices, reminders and receipts. It runs either on a domain you verify or on a domain we already operate. Nothing about invoicing changes when you switch it on; what changes is where the message leaves from and which log you read.

Tiers and volume: 10,000 emails a month on Mail Shared, 50,000 on Mail Custom, custom above that. Overage is $0.90 per 1,000 emails and is billed on the same invoice as the subscription.

06Your data#

Export everything at any time from Settings → Data as CSV plus the original PDFs, in one archive. Closing the account starts a 30-day window in which the export stays available; after that, records we must keep for tax purposes (issued invoices, ten years) are retained and everything else is erased.

For an access, correction or deletion request under the UU PDP, write to [email protected] — the full procedure is in our privacy policy.

07Reporting a security issue#

Write to [email protected] with enough detail to reproduce the issue. We acknowledge within one Business Day, keep you informed until it is fixed, and do not pursue legal action against researchers who act in good faith, stay within their own accounts, and avoid privacy violations or service disruption. We credit reporters in the release notes if they want that.

08Talk to a person#

Nothing here matched your situation? Write to us — a support engineer answers, not a bot, and we will ask for the invoice number and the time it happened so we can look at the actual delivery log.
