Award-winning eSignature solution

Legal validity and compliance considerations

In the United States electronic signatures executed through compliant services meet ESIGN and UETA requirements and can be admissible in court; construction firms should maintain audit logs, signer authentication, and document retention aligned with contract and regulatory obligations.

Legal validity and compliance considerations

Typical user roles and responsibilities

Project Manager

Project Managers prepare and approve proposal content, choose appropriate templates, coordinate signers and subcontractor inputs, and confirm that signed proposals are archived with project metadata for downstream procurement, permitting, and invoicing processes.

Account Administrator

Administrators manage user access, maintain the template library, configure signing workflows and retention policies, and review audit logs to ensure compliance with internal controls and contract management requirements.

Core features to streamline construction proposals

Essential tools help construction firms prepare, send, and track proposals more consistently while preserving legal and audit records required for procurement and compliance.

eSignature

Electronic signatures capture intent and consent with time stamps and signer details, producing admissible evidence in U.S. jurisdictions under ESIGN and UETA while simplifying on-site approvals and remote signings.

Templates

Reusable, role-based templates speed proposal creation by standardizing scopes, pricing, and contract clauses so teams issue consistent documents with fewer manual edits and version issues.

Bulk Send

Bulk Send enables sending identical proposals or Acknowledgements to multiple recipients at once, reducing repetitive work for mass bid invitations, subcontractor notices, or vendor confirmations.

Document Editor

Built-in editors let you modify proposals, insert conditional sections, and add fields without external tools, reducing back-and-forth between proposal drafting and signature preparation.

Audit Trail

Comprehensive logging captures signer IP, timestamps, and field interactions to support dispute resolution, compliance audits, and contractor recordkeeping for projects.

Integrations

Prebuilt connectors with CRM, cloud storage, and project management systems reduce manual data entry and keep proposal records synchronized across construction workflows.

Integrations and template capabilities that matter

Integration with document editors, cloud storage, and CRM systems plus rich template options reduce manual tasks and keep proposals consistent across projects.

Google Docs

Two-way integration enables drafting proposals in Google Docs then sending for signature without manual downloads; field mapping preserves variables and contract metadata for consistent storage and auditability in a single workflow.

CRM integration

Native connectors with Salesforce, HubSpot, and other CRMs let you generate proposals from opportunity records, sync status updates, and store signed agreements on the customer record to maintain deal history.

Cloud storage

Direct links to Dropbox, Google Drive, and OneDrive let you archive signed proposals alongside project files, ensuring consistent backups and centralized document management for contractors and owners.

Custom templates

Template libraries with variables, conditional sections, and approver workflows let teams enforce contract language, pricing structures, and required attachments for each project type and client.

How online proposal creation and signing operates

The online process turns draft proposals into signed agreements by uploading documents, applying form fields, assigning signers, and capturing legally admissible signatures with a complete audit record.

  • Draft: Prepare proposal content in your editor or upload PDF.
  • Prepare fields: Drag signature, initials, dates, and input fields into place.
  • Assign signers: Add recipients, set signing order, and include signer details.
  • Capture signature: Send for signing and record final signed document with audit trail.

Real-world construction use cases

Practical examples illustrate how proposal software reduces turnaround, improves accuracy, and maintains contract records across common construction scenarios.

General contractor bid turnaround

A general contractor converts reused scopes and pricing into standardized proposal templates to reduce manual drafting time and eliminate formatting errors.

  • Uses role-based templates and prefilled schedules to cut review cycles.
  • Collects signatures from owners and subcontractors via mobile devices on-site.

Resulting in faster bid acceptance, fewer version conflicts, and clearer audit records that support timely project starts and invoicing.

Subcontractor compliance and onboarding

A subcontracting firm sends standardized proposals containing insurance and compliance attachments to multiple primes and clients for signature and verification.

  • Integrates proposal delivery with document storage and compliance checklists.
  • Tracks signed certificates and submittals tied to each project folder.

Resulting in simpler contractor onboarding, reduced paperwork errors, and improved readiness for compliance audits and payment processing.

Best practices for secure and accurate proposal processing

Adopt consistent processes and controls to improve speed, reduce disputes, and maintain compliant records when issuing construction proposals and contracts.

Standardize templates across teams and projects
Maintain a central template library with approved contract language, pricing tables, and conditional clauses to reduce drafting errors and ensure consistent legal terms across proposals and subcontractor agreements.
Use role-based permissions and approvals
Limit template editing and signature requests to authorized roles, require managerial approval for high-value bids, and enforce signer verification steps to reduce unauthorized changes or accidental sends.
Capture required evidence with each signature
Enable audit trails, signer authentication, and required attachment fields for insurance certificates or permits so each signed proposal includes the documentation needed for compliance and payment.
Retain and index signed proposals reliably
Adopt an archival policy that stores signed proposals with metadata tied to project IDs and contract milestones to support audits, claims, and long-term record retrieval.
