Invoices and receipts
Every payment you make to Synacl produces an invoice. It's emailed to you when the payment goes through, and it stays available to download for as long as your account exists.
Finding your invoices
Go to Settings → Plan & Billing. The Billing History card lists every payment on your account, newest first:
| Column | What it means |
|---|---|
| Date | When the payment was made |
| Plan | What you paid for |
| Invoice | Your invoice number, e.g. SYN-INV-2026-00042 |
| Amount | What was charged, in the currency it was charged in |
| Status | Paid once the money has cleared |
| Receipt | Download the PDF |
Auto-renewing subscription charges appear here too, alongside one-off purchases — so a year of monthly renewals shows as twelve rows, each with its own invoice.
Payments that aren't plan purchases are listed as well, labelled so you can tell them apart: Data overage for an enterprise usage charge, and Enterprise prepayment for a quote you paid up front. Both get an invoice number and a PDF like any other row.
If you paid an enterprise quote from an email address that doesn't have a Synacl account, the receipt is emailed to you but there's no billing page to list it on. Keep that email — contact support if you need it re-sent.
Downloading a PDF
Press PDF on any row. The file is generated fresh each time and named after the invoice number, so it's safe to hand straight to whoever handles your expenses.
Quoting an invoice number
Invoice numbers look like SYN-INV-2026-00042 and are unique to your account's issuing
series. Quote the whole thing when you contact us about a payment — it identifies the
charge far more precisely than a date and an amount.
If your invoice number contains TEST (SYN-INV-TEST-2026-00003), it belongs to a test
transaction and no real money moved. You'll only ever see one of these if you were
deliberately testing checkout.
Tax
Synacl is not currently registered for GST, so no GST is charged on your purchase and no tax is itemised on your invoice. The amount on the invoice is the amount you paid.
If your own accounting needs a GST breakdown, there isn't one to give — this is a supply from an unregistered supplier, and the invoice is correct as issued. Should that change, tax will be shown as its own line and the total will still be the amount you actually paid, never a figure with tax added on afterwards.
"I never got my invoice"
First, check the spam folder — invoices arrive as an email with a PDF attached, which some filters treat harshly.
If it isn't there, you don't need to wait for us to notice. The invoice is already on your Billing History and you can download the PDF yourself right away. We also retry failed deliveries automatically for a while after the payment.
If the invoice isn't listed at all a few minutes after paying, contact support with the date and amount, and we'll track down the payment.
Changing the details on an invoice
An invoice records your billing details as they were when it was issued — that's what makes it a valid record. Updating your address under Settings → Profile changes future invoices, not past ones.
If an already-issued invoice has genuinely wrong details on it, contact support rather than re-issuing: an invoice number can't simply be reused once it's been given out.
