Docusign App Center Extension App Development
One fixed price takes your integration from kickoff to a complete App Center submission in four weeks — architecture, build, security review, full public documentation, and the submission pack, then managed through Docusign's review. Hosting and maintenance are priced on this page too, so nothing about the lifecycle is a surprise.

Two ways to use an extension app
FOR ISVS & PLATFORM VENDORS
Your product, inside Docusign.
An App Center listing is distribution: your platform running natively inside Docusign agreement workflows, in front of Docusign's customer base. The listing carries your brand and your ISV identity — we do the engineering, the documentation, and the submission.
- Published under your brand in the Docusign App Center
- Public documentation your customers can read
- Submission and review process managed for you — up to 2 resubmission cycles included
FOR ENTERPRISES
A private extension for the systems you already run.
The same engineering without the public listing: connect Docusign to your ERP, CRM, or internal platform with a private extension deployed to your own account. No marketplace, no exposure — just your agreement data flowing where it needs to.
- Private to your Docusign account — no public listing
- Connects one internal or vendor system, deeply
- Same 4-week build, same documentation standard
Extension App Types We Build
Data I/O Apps
Bidirectional data exchange between Docusign and external systems. Sync agreement data, customer records, project details. Features: dynamic schema generation, field mapping, row-level sync, delta updates.
File Archive Apps
Store executed documents in external platforms (cloud storage, archives, repositories). Retrieve signed documents on-demand. Enables compliance, long-term storage, and system-of-record integration.
Connected Fields Apps
Real-time field-level integrations. Map external data directly to Docusign fields. Auto-populate template fields from customer systems, enable live lookups during signing.
Side-panel Apps
Embedded UI components within partner applications. Launch Docusign signing experiences directly from your app. Seamless integration without leaving the platform.
Four apps live. Six more in development.
We build, submit, host, and maintain Docusign extension apps as a Docusign Build IAM Specialized Partner. Every app we ship comes with public documentation — read it yourself.
Xero
AccountingInvoice-to-agreement validation and vendor onboarding. Connect financial events to Docusign agreement processes.
Smartsheet
Work ManagementTwo-way sync between Smartsheet and Docusign agreements. Push signed data to sheets, archive documents, trigger workflows.
Zoho CRM
Sales & CRMDeal-to-agreement automation. Closed-won deals trigger the right contract workflow with data pre-populated from Zoho.
BambooHR

Kickoff to App Center submission in 4 weeks
As a Docusign Build IAM Specialized Partner, we build against the App Center's review criteria from day one — so week 4 ends with a complete submission, not a to-do list. Docusign's post-submission review runs on its own clock; we manage the process — reviewer feedback answered, resubmissions handled. Approval itself is Docusign's call.
Scope & Architecture
App scope confirmed — typically Data I/O + File Archive together (they pair naturally; Connected Fields ships as its own app). Data flows mapped, your platform's API assessed (auth, rate limits, schemas), field mappings designed.
Week 1Build
The heart of the engagement — two full weeks building on Docusign's extension framework: OAuth 2.0 flows, webhook handlers, sync and error-handling logic against your platform's API.
Weeks 2–3Test, Document & Submit
End-to-end testing against the App Center review criteria, security and compliance checks, the full technical documentation written to the same public-docs standard our live apps ship with — and the submission pack finalized and filed: listing assets, demo materials, security questionnaire.
Week 4App Center Review
Docusign's review team takes it from here — external time on Docusign's clock, not ours. We manage it: respond to reviewer feedback, handle resubmissions, and publish the listing when it's approved.
Post-submissionThe partner that has already shipped through the review
Docusign Build IAM Specialized Partner
Docusign's specialization for partners building on the IAM platform — the credential behind every app we've shipped to the App Center. We know the review criteria, the documentation requirements, and the common rejection points, because our own apps went through them.

FIXED FEE
$25,000
1 published App Center extension app
Typically Data I/O + File Archive together — they pair naturally: two-way data sync plus signed documents archived in your system of record. Connected Fields is architecturally a separate app; adding one later is a fixed change order from the printed menu, never hourly.
1 external-system integration
OAuth 2.0 against one platform API: authentication, field mapping, sync logic, error handling and retries.
Security review & compliance testing
Built to the App Center review criteria: encryption, audit logging, PII protection.
Full technical documentation
The public-docs standard our live apps ship with — installation, configuration, usage, troubleshooting — published and linkable.
App Center submission pack + managed review
Listing assets, demo materials, security questionnaire — filed in week 4, with up to 2 resubmission cycles included and managed for you.
30-day post-launch fix window
Capped at 10 hours. Anything in the accepted scope that breaks in the first 30 days is fixed free.
Payments are milestone-gated to proof — agreed at kickoff, never hourly. Hosting is deliberately not in this list: it's a separate attach, priced below, so you always know what recurs.

Frequently Asked Questions
What is a Docusign extension app?
An extension app runs inside Docusign agreement workflows and connects them to an external system. There are four types — Data I/O (two-way data sync), Connected Fields (live field-level lookups during signing), File Archive (signed documents stored in your system of record), and Side-panel (your app embedded in the workflow UI). Data I/O and File Archive pair naturally and typically ship together as one app; Connected Fields is architecturally a separate app. Extension apps are distributed through the Docusign App Center, or deployed privately to a single account.
What exactly does the $25,000 include — and what costs extra?
Included: one published App Center extension app — typically Data I/O + File Archive together — connected to one external system; security review and compliance testing; full technical documentation; the App Center submission pack with the review process managed; and a 30-day post-launch fix window. Anything beyond a cap is a fixed-price change order from the printed menu — an additional app type (for example, Connected Fields as its own app at $15,000) or an extra external system never bills hourly. Hosting is not bundled: it's a separate attach at $3,000 for the first 6 months, so you always know what recurs.
How long until our app is live in the App Center?
The engagement is 4 weeks: one week of scoping and architecture, two full weeks of build, and a final week of testing, documentation, and submission. Docusign's App Center review then runs on Docusign's clock — external time we don't control, so we don't pretend to. What we do control: the app is built against the review criteria from day one, and we manage the process — responding to reviewer feedback and handling resubmissions — until it's approved and live.
What happens if Docusign's review comes back with changes?
We handle it. Our live apps went through the same review, so we build to the known criteria — documentation requirements, security expectations, common rejection points — before submission. If reviewer feedback still comes, we respond and resubmit for you, with up to 2 resubmission cycles included in the fixed fee.
Who owns the app, the code, and the listing?
You do. The code and IP transfer to you on final payment. For ISVs, the App Center listing is published under your ISV identity, so your brand — not ours — faces Docusign customers. If you'd rather not run the listing operationally, we can manage it on your behalf.
What documentation comes with the app?
Full technical documentation is included — the same public-docs standard as our live apps: installation, configuration, how to use the app, known behaviors, and troubleshooting. Read the Xero, Smartsheet, Zoho CRM, or BambooHR documentation on this site to see exactly what you'll get.
Who hosts the app after launch?
An extension app is a running service — it needs production infrastructure with monitoring and App Center-grade compliance. Hosting isn't inside the $25,000: the hosting attach covers your first 6 months for $3,000, then standard Partner Hosting plans start at $599/month. Same team, same infrastructure our own live apps run on.
What happens when Docusign updates the platform?
Docusign's APIs and review requirements evolve. The maintenance plan — $1,500/month with roughly 15 hours of engineering included — keeps your app compatible: platform-update fixes, bug fixes, small feature updates, and listing upkeep.
Can we keep the app private instead of publishing it?
Yes. Enterprises often want the same integration without a public listing — a private extension connected to internal systems, deployed to your own Docusign account. Same build, same 4 weeks, same documentation standard; no App Center distribution step.
