Issue an invoice
Open Business → Invoices. Select the owner, permitted seller/storefront and currency before entering line items. Confirm descriptions, quantity, prices, discount, tax and due date before issue. Invoice issue freezes seller identity, address, tax identifier, local logo and footer. Later brand changes do not rewrite issued documents. Historical or imported invoices may be read-only; follow their displayed reconciliation controls.
Invoice numbering is configured in System → Business & billing. Choose country/custom format, an allowed custom prefix, 6–9 digits, positive increment and next number. The next value must fit the digit count and exceed the highest issued sequence. Existing numbers are retained; brands share the locked sequence so independent counters cannot collide.
Download and email
The customer can open their issued invoice and download its PDF from My account → Invoices with billing visibility. Staff PDF access has its own permission checks. The PDF is rendered from the issued record, not a URL supplied by the customer. Billing mail uses the invoice's stored recipient and attaches that matching PDF; missing renderer readiness can hold delivery before SMTP submission.
Statements/export and staff reports retain separate currencies. A PDF or CSV download is a read operation, not payment evidence. Keep downloaded financial documents private. When a PDF fails, preserve the invoice and repair renderer/runtime readiness rather than editing financial values to make generation succeed.
Bulk and outstanding balances
Use the bulk workspace's preview and explicit confirmation. Review selected customer, seller, currency and eligible invoices; protected, paid, cancelled or conflicting records may be held. Revalidate a changed selection instead of replaying an old preview. A merge must preserve the source-order references and cannot mix unrelated accounting identities.
Pay or cancel
Available online and offline methods are determined by the invoice's stored seller, country and currency. Pending payment evidence or an uncertain checkout prevents conflicting submission. A cancellation is allowed only when the displayed financial/delivery guards pass. See settlement and refunds and bank methods.
