Custom Templates
Create reusable invoice templates that embed project codes, standardized line items, conditional fields for hourly versus milestone billing, and branding to ensure consistency across engineering engagements.
Invoices and eSignatures for consulting services for engineering are legally enforceable in the United States when they meet ESIGN and UETA requirements; maintain records, consent, and reliable attribution to support admissibility under U.S. law.
A consulting engineer prepares detailed invoices that reference project phases, deliverables, and hours. They require templates that capture technical descriptions and the ability to attach supporting design documents or timesheets for client review and validation.
An accounting manager validates invoice calculations, enforces payment terms, and manages retention policies. They need integration with the general ledger, audit trails for approvals, and exportable records for tax and compliance purposes.
Create reusable invoice templates that embed project codes, standardized line items, conditional fields for hourly versus milestone billing, and branding to ensure consistency across engineering engagements.
Built-in formulas compute hours times rates, apply taxes and discounts automatically, and update totals to reduce manual arithmetic errors and speed approval cycles for consulting invoices.
Secure eSignature capture directly on the invoice lets clients approve charges quickly while producing a tamper-evident record and reducing paper handling for client authorization.
Comprehensive logs record every action on an invoice, including edits, views, and signatures, supporting dispute resolution and providing evidence for internal controls and compliance reviews.
Connect invoices to accounting, CRM, cloud storage, and project management systems to sync client data, push finalized invoices to ledgers, and attach supporting documentation automatically.
Assign roles and permissions so billing staff, project managers, and approvers have appropriate access to create, edit, or send invoices while maintaining separation of duties.
Create or import invoice content from Google Docs, merge client and project fields automatically, then convert to a secure PDF ready for signature while preserving formatting and attachments for technical schedules.
Sync contact records, project codes, and billing rates from CRM systems so invoices populate client data accurately, reducing duplicate entry and ensuring ledger consistency when invoices are finalized.
Automatically store signed invoices and supporting files in Dropbox or other cloud repositories with folder rules by client or project to maintain an organized, searchable archive.
Design invoice templates that include engineering-specific sections, such as scope descriptions, deliverable lists, timesheets, and retainers, enabling consistent presentation and faster approvals.
