Award-winning eSignature solution

Legal validity and compliance considerations

Electronic billing invoices signed with compliant eSignature processes are admissible and enforceable under U.S. laws such as ESIGN and UETA when signatures, consent, and records meet statutory requirements.

Legal validity and compliance considerations

Roles and permissions for invoice workflows

Accounts Receivable

Accounts Receivable users prepare invoices, apply payment terms, and reconcile signed invoices to payments. They require edit privileges for invoice creation, visibility of client payment history, and ability to trigger reminder workflows.

Finance Manager

Finance Managers approve high-value invoices, manage templates, and review audit logs. They need administrative visibility, the ability to set approval chains, and access to export signed documents for financial close and compliance reviews.

Essential features for accurate billing invoices

Effective invoice examples combine template controls, calculation automation, audit logging, integrations, secure signing, and retention settings to support accounting accuracy and compliance.

Template controls

Field locking and conditional logic let accounting teams standardize invoice layouts, prevent accidental edits to critical fields, and ensure required data is always present before sending.

Automated calculations

Line-item subtotals, tax computations, discounts and totals update automatically to eliminate manual math errors and maintain consistent figures across sent invoices.

Audit logging

A detailed event log records views, edits, signature actions, and delivery timestamps to support reconciliations and internal controls for billed amounts.

Integrations

Connectors to accounting software, CRMs, and cloud storage streamline data flow, reduce rekeying, and ensure invoice data maps correctly to ledgers and client records.

Secure signing

Electronic signature options with authentication steps and tamper-evident sealing preserve the integrity of signed invoices and create admissible records.

Retention policies

Configurable retention and archival controls capture signed invoice copies and ensure compliance with recordkeeping schedules and audit readiness.

Integrations and template customization

Google Docs

Use Google Docs templates to draft invoices, then convert and push finalized invoices into the eSignature workflow while maintaining version control and collaborative editing history for pre-sign reviews.

CRM sync

Map client records from CRM systems so invoices auto-populate contact, billing address, and payment terms, reducing duplicate entry and improving billing accuracy for repeat clients.

Dropbox integration

Store signed invoice copies and supporting documents in a structured Dropbox folder per client, enabling centralized archival and easy retrieval for audits.

Custom templates

Create role-specific invoice templates with locked fields and conditional sections so accountants, sales reps, and project managers each use a tailored format while preserving core accounting data.

Best practices for secure, accurate invoicing

Adopt consistent controls, template governance, and verification steps to reduce errors and maintain compliance across billing invoice workflows.

Standardize templates and field validation
Use centrally managed templates with required field validation and conditional logic to prevent missing or inconsistent invoice data. Maintain a change control process so template updates are reviewed and approved by accounting before use.
Implement approval routing for high value invoices
Configure multi-step approval workflows that require manager or finance sign-off for invoices exceeding defined thresholds to reduce risk of incorrect billing and ensure accountability for large transactions.
Preserve audit trails and export logs regularly
Schedule periodic exports of audit logs and signed invoice copies to secure archival storage. Retain logs according to corporate retention policy and ensure exports include signer metadata and timestamps for audit readiness.
Test integrations and access controls
Validate mappings to accounting and CRM systems in a staging environment, and review role-based access settings to ensure staff only have the privileges needed for invoice creation and approval.
