What is already in the product
Build an invoice manually or carry the agreed quote lines into a new invoice.
Statuses distinguish drafts, sent invoices, partial balances, paid records, overdue amounts and void documents.
Use TPS, TVQ, custom tax handling and tax-exempt lines where the invoice requires them.
Public print and PDF views provide a clear invoice record without exposing the administrative workspace.
Capture partial and manual payments, internal installment schedules and credit notes against the invoice history.
Bulk actions help the office work efficiently, and an optional completion rule can create a draft without sending it automatically.
How the handoff works
Every major workflow answers the same five questions: what starts it, which rules apply, what Serberus completes, when it asks, and where the result remains visible.
The office creates an invoice, converts a quote or completes a job with draft creation enabled.
You set taxes, payment terms, installment details, invoice timing and who may edit financial records.
Serberus prepares the document, tracks its state and updates the recorded balance as entries are added.
It asks before a draft is sent, a credit changes the balance or a person must confirm a financial exception.
See the invoice, public document, balance history, audit log and financial reports.

From office to field
The same request, schedule, customer details, photos, notes, status, and next action stay available as work moves from the office to the site.
