Subscription
A period invoice from a schedule — or a manual line that is not going to repeat. Credit notes live here. Prepaid quota sits beside the invoice, not inside it.
07 · Invoices
Drafts are for review. Sent documents freeze.
Once sent, Sonic will not pile new lines onto it. A later charge is a new invoice alongside. A correction is a credit note or an adjustment — never a silent rewrite.
The list
Drafts waiting to go out. Sent invoices waiting to be paid.
Every invoice Sonic has produced. The bill-to is the customer, or the shipper in a freight workspace. Drafts you check, then send. Overdue you chase in Watchtower. Paid is done. Void is cancelled — still visible, zero balance.

Drafts accept lines. Sent, paid, and void invoices never do.
Two families
Subscription and shipment never share a document.
Schedules, usage, seats, and a one-off true-up produce subscription invoices. Freight comes from Shipment uploads. The two are never mixed, even if a workspace later runs both engines.
Shipment
From you or the carrier, billed to the shipper. One haul can keep a mapped document number; several hauls use shipper–carrier–window. No credit notes — correct the file, or void.
What kind of invoice
Standard is the period bill. The others exist so a sent document never has to be rewritten.
Standard
The normal invoice for a billing period, or a grouped freight window.
Advance
Payment up front that grants prepaid quota. The balance lives on Prepaid — not as extra lines later.
Overage
Usage or seats past that quota. Billed on its own invoice, merged daily.
Adjustment
They owe more after a sent invoice — an upgrade, or a quantity that went up. Linked back to the original.
Sending
Sending is the freeze — and the start of everything else.
It writes the PDF, mails the billing contacts, posts the journal if recognition is on, starts the Watchtower clock, and adds the amount to receivables. If a note says this invoice gates a subscription, recording payment starts the term.
Corrections
After send, the correction is a second document.
Raising a credit note does not return cash — apply it, or refund through the provider. Freight has no credit notes: fix the shipment in the file, or void the invoice.
Still a draft
Edit lines, dates, and tax. Void it if it should never go out.
Credit note
They owe less — a downgrade, a refund, a duplicate. Subscription workspaces only.
Adjustment
They owe more. The extra document carries the days that actually changed.
Void is not delete
Zero balance, still visible. Auditors expect that. Issued invoices are never rewritten.
