Template fields
Custom fields for project codes, sprint numbers, and client PO numbers let you standardize invoices for repeat engagements and filter records by project attributes when exporting or importing into accounting systems.
A freelance product manager bills a mix of retainer and hourly work; a simple invoice template saves time by standardizing fields such as sprint numbers, discovery fees, and travel expenses. This consistency makes it easier to reconcile payments, track unpaid invoices, and demonstrate scope alignment with clients during reviews.
An agency billing manager consolidates invoices from multiple contributors, applies client-specific billing rules, and ensures compliance with purchase orders. A standardized template with project codes and expense categories streamlines monthly client statements and reduces manual adjustments during reconciliation.
The template is valuable to independent contractors, small agencies, and internal product teams who bill clients or allocate costs across projects.
Standardized templates reduce errors, simplify bookkeeping, and create a consistent record for payments and client communications across diverse product management engagements.

Built-in formulas compute line totals, taxes, and discounts automatically to reduce math errors and ensure consistent totals across invoices, especially when dealing with hourly versus fixed-price tasks.
Support for multiple currencies, tax rates, and VAT settings helps product managers billing international clients avoid manual conversions and keep tax handling consistent by client jurisdiction.
Line-item support for time entries, milestones, and expenses allows precise billing for discovery, roadmap planning, and iteration work while preserving a clear breakdown for client review.

CSV and PDF exports plus simple reporting let you reconcile invoices with bank deposits, track outstanding balances, and provide summaries for quarterly tax reporting or client statements.
