Send, Sign, And Track Documents Without Leaving MangoApps
MangoApps E-Signature lets any authorized user send documents for electronic signature with visual field placement, multi-signer routing, automatic reminders, and a tamper-evident signing certificate — without paying per-envelope to a third-party signing tool.
What E-Signature Helps You Do
Drop Fields Visually
Upload a PDF or document and drag signature, initial, date, text, checkbox, radio, and dropdown fields onto exactly the right spots — assigned to the correct signer.
Route Multiple Signers
Sequential or parallel signing with named signers, optional CC recipients, and external (non-MangoApps) signers via email.
Detect Fields With AI
AI field suggestions look at the document and propose where signature, date, and initial fields belong. Accept the suggestions or edit them.
Generate Certificates
Every completed envelope gets a tamper-evident signing certificate — signer identity, IP, audit timeline, and document hash — appended to the final PDF.
Auto-Remind
Automatic reminders fire on the cadence the sender chose. Expiration handling closes stale envelopes; senders re-send or extend with one click.
Summarize & Q&A
AI summarization gives signers a plain-English overview of what they're signing. Document Q&A lets them ask specific questions before they sign.
Built For Real Document Workloads
Three capability blocks that make e-signature feel native to the workforce platform.
Visual Field Placement With AI Suggestions
Upload any PDF, Word doc, or generated document. Drop signature, initial, date, text, checkbox, radio, and dropdown fields exactly where they need to go. Or let AI Field Suggestions detect where they belong from common document layouts (offer letters, NDAs, policy acknowledgments).
- 7 field types — signature, initial, date, text, checkbox, radio, dropdown.
- Per-signer assignment — each field tied to a specific recipient.
- AI Field Suggestions — common layouts auto-detected.
- Reusable templates — save a configured document for repeat sends.
AI Risk Detection And Document Q&A
Before signing, recipients can summarize the document, ask plain-English questions, and see automatic risk flags (auto-renewal clauses, unusual liability terms, indemnification). Signers ship informed, not blind.
- Document summarization — plain-English overview of what's inside.
- Document Q&A — ask specific questions, get sourced answers.
- Risk detection — flag unusual terms before signers commit.
- Per-tenant toggles — disable AI features if policy requires.
Legally Binding Audit Trail
Every action — viewed, signed, declined, reminded, expired — captured with timestamp, IP, and signer identity. The signing certificate is appended to the final PDF. Tamper-evident hashing means a single byte change voids the certificate.
- Signing certificate — appended to every completed PDF.
- Per-event audit log — viewed, signed, declined, reminded.
- Document hash — tamper-evident; signature voids on change.
- Identity verification — internal users via MangoApps SSO; external via email link.
E-Signature In Practice
A practical scope check: what the app covers, which controls matter, and the workflows teams usually run first.
Core workflow
Send documents for electronic signature with a visual drag-and-drop field placement editor.
Controls that matter
Signing Workflow includes Multiple signers with configurable signing order and External signers (no account required).
Scope and specs
Useful specs: Default request expiration: 30 days (admin-configurable); Default reminder frequency: Every 3 days (admin-configurable); Accepted document format: PDF only.
Employment offer letters
HR sends offer letters with signature and date fields to candidates who sign electronically from any device.
Contractor agreements
Legal prepares NDA or service agreements, places fields for multiple parties, and tracks signing progress in real time.
Policy acknowledgments
Distribute updated company policies to all employees and collect signatures with completion tracking and reminder automation.
Connected To The Rest Of MangoApps
→ Forms
Form submissions can capture a legally binding signature via E-Signature. The signing certificate lives with the submission record.
See Forms→ Contracts
Contract approvals route through E-Signature for the final signature stage. Renewals re-send automatically.
See Contracts→ Offer Manager
Offer letters generated in Offer Manager send for e-signature with one click. Candidate signs, offer closes.
See Offer Manager→ Policy Hub
Policy acknowledgments capture an explicit signature when the policy requires one — not just a checkbox.
See Policy Hub→ Meal Compliance
Meal-break waivers route through E-Signature with auto-invalidation when behavior changes.
See Meal Compliance→ Drive
Signed PDFs save into Drive automatically — searchable, permissioned, and tied to the sender's workspace.

One signing surface in place of per-envelope vendor fees
Most companies running e-signature pay per envelope to a third-party tool — and still maintain a separate template library, a manual reminder process, and an export-and-file step into shared drives. E-Signature folds the workflow into the platform and stops the envelope meter.
DocuSign
The category-defining e-signature service
- One per-employee suite price — no per-envelope or per-sender fees that scale with HR offer letters and policy sign-offs
- Signed PDFs save automatically into Drive, Workspaces, and the originating record — no manual download-and-file step
- Same identity perimeter and audit log as the rest of the platform — not a separate DocuSign tenant for security to re-certify
Adobe Acrobat Sign
Adobe's enterprise e-signature
- Visual field placement, multi-signer routing, and reminders included — Acrobat Sign Standard misses pieces and forces Pro tier
- Counterparties sign without an Adobe account — same friction-free flow on mobile and desktop
- AI field detection runs in-app — no separate Adobe Sensei subscription
Dropbox Sign (HelloSign)
Dropbox's e-signature product
- Scales past the small-business plan ceiling — multi-tenant, enterprise SSO, and SCIM are first-class
- Signature requests trigger automation in the platform — Onboarding, Policy Hub, and HR can fire a signature request from the workflow that generated the document
- Audit log spans authoring, signing, and storage in one record — not Dropbox + HelloSign + the recipient's email
PandaDoc
Documents-led e-signature and proposals
- Visual field placement, conditional logic, and bulk send are built into the per-employee price — PandaDoc gates them behind tiers
- Integrates with Contracts, Procurement, and HR workflows — no separate PandaDoc-to-everything integration to maintain
- AI risk detection and field auto-fill come built-in, not as premium add-ons
SignNow / signNow by airSlate
Mid-market e-signature
- One per-employee suite license replaces signNow plus the workflow tools it bolts on — fewer vendors, fewer renewals
- Tamper-evident signing certificates and ESIGN/UETA compliance are baseline — not premium-only features
- Same audit trail as Contracts, Onboarding, and HR — not a signNow-only event stream
PLATFORM LEVERAGE
E-Signature inherits everything else MangoApps already does
A point e-signature tool has to build, buy, or integrate each of these. E-Signature gets them for free because the platform already runs them.
Identity & SSO
Inherits your SAML/OIDC SSO, MFA, and SCIM provisioning. Senders use the same login as everything else — counterparties sign without an account.
HRIS-synced senders
Authorized senders, departments, and roles come from the live HRIS — offboarded employees can't send envelopes the next day.
Drive integration
Signed PDFs save into Drive automatically — searchable, permissioned, and tied to the originating workspace or record.
Workflow & automation
Onboarding offer letters, policy acknowledgments, and contract renewals fire signature requests automatically — one automation engine.
Audit log & retention
Every envelope, view, and signature event lands in the same audit log Legal and Compliance already use across the platform.
AI field detection
Field placement auto-detects from the document using the platform's AI layer — no Acrobat Sensei or PandaDoc AI as a paid add-on.
INDUSTRY FIT
Built for the operations where signature volume is real money
E-Signature fits every employer that needs a signature, but it earns its keep where the per-envelope bill from a point tool has become a budget line item.
HR & Onboarding
Offer letters, NDAs, I-9s, and policy acknowledgments signed from the same Onboarding workflow — no per-employee envelope cost.
Healthcare
Patient consents, BAAs, and credentialing forms signed with HIPAA- friendly logging and a complete audit chain.
Financial Services
Account-opening forms, counterparty agreements, and disclosures with ESIGN/UETA-compliant signing certificates and audit-ready exports.
Real Estate
Listing agreements, leases, and disclosure packets signed by agents and clients without per-transaction envelope fees.
Field Services
Customer estimates, work-completion sign-offs, and recurring service agreements signed on the tech's tablet at the kitchen table.
Public Sector
Procurement contracts, agency forms, and citizen-facing agreements with FedRAMP-eligible deployment and full audit history.
WHY MANGOAPPS WINS
One platform beats a stack of point solutions on every axis
The argument finance, legal, HR, and IT all share — and the one an e-signature point tool structurally cannot answer.
Cheaper than the stack
One per-employee suite license — no per-envelope, per-template, or per- sender fees as your signature volume scales with HR and Contracts.
More secure
One identity perimeter, one audit log, one retention policy across every signature event. Nothing for security to re-certify each year.
Easier to deploy
Already deployed if you have MangoApps. Configure a template, send your first signature request the same day — no separate vendor procurement.
Easier to use
Senders work from the app they already use. Counterparties click a link and sign on any device — no account, no app install.
Easier to manage
Authorized senders come from the HRIS — offboarding immediately revokes the ability to send. No parallel DocuSign user list to maintain.
Easier to extend
A signed document can fire onboarding, an HR record update, a contract activation, or a Drive save — one engine, every app.
AI is actually better
E-Signature AI tracks pending signatures, sends nudges, and detects risky clauses — grounded in your own templates and history, governed by the same permission model.
Pair E-Signature With AI
E-Signature AI tracks pending signatures, signing progress, and overdue envelopes — with one risky write (send_bulk_reminders) gated by explicit confirmation.
E-Signature AI
10 tools across pending, progress, audit, and AI field suggestions.

At our head office within HR, marketing, and finance, we use ChatGPT quite a bit, and MangoApps AI Helper is a useful tool for us. As I go around to the stores, I’ve been showing them how the AI Intranet Helper can find things and answer plain language questions about our resources, and they’re quite excited about that.

Frequently Asked Questions
Yes. Each completed envelope produces a tamper-evident signing certificate appended to the PDF, including signer identity, IP, timestamp, and a document hash. The hash voids the certificate if a single byte changes after signing — the same standard third-party tools use.
Yes. External signers receive an email with a tokenized signing link. Identity is verified by the email link and the audit log captures the same metadata as internal sends. The allow_external_signers toggle controls availability.
Same field types, same multi-signer routing, same audit trail — no per-envelope pricing. Plus AI features (summarization, Q&A, risk detection, field suggestions) and integration with Forms, Contracts, and Policy Hub that third-party signing tools can't offer.
Yes. The who_can_send setting offers all users, managers only, or admins only. External signer access and AI features each have their own toggle.
Upload a document. The AI looks at layout (signature blocks, "Date:" labels, "Initial here" markers, signature lines) and proposes field placements. Senders accept, edit, or override every suggestion — nothing is placed without explicit confirmation.
Risk detection flags common legal hazards — auto-renewal clauses, unusual liability terms, indemnification language, payment terms outside standard ranges. Each flag is informational; the human decides whether to sign or escalate.
Tracks pending signatures, signing progress, overdue envelopes, audit timeline, and AI field suggestions in chat. Most operations are read; one bulk write (send_bulk_reminders) is confirmation-gated. See the agent for the full list.
