Why teams connect Bill and Docusign
Connect the financial records in Bill with the work happening in Docusign, so both stay current without exports or copy-paste.
Bill holds the financial truth: who the customers are, what they were billed, what they paid. Docusign is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.
Stacksync keeps Vendors, Invoices, Customers, Payments in Bill and Documents, Templates, Tabs (form fields), Envelope Custom Fields in Docusign in sync, bi-directionally and in real time. Whatever records Docusign keeps and whatever events it produces, the overlap with Bill is mapped field by field, and a change on either side shows up on the other within seconds.
There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.
Common use cases
- 01 Read approved Bills and their line items into a Postgres warehouse for spend, accrual, and cash-flow reporting without CSV exports.
- 02 Sync Customers and Invoices from BILL AR into a CRM or ERP so sales and finance see billing and payment status on the account.
- 03 Extract Tabs data captured from signers — text fields, checkboxes, dates — into a warehouse to populate downstream contract or onboarding tables.
- 04 Push signed Documents and the certificate of completion into a document store or database keyed by Envelope Custom Fields for audit and retrieval.
Common sync patterns
Where Docusign tracks people or companies: one identity
A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.
Where Docusign handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Bill next to the customer they are helping, without logging into the finance system.
Where Docusign collects payments or triggers charges: events land in Bill
Payment and charge activity flows into Bill as it happens, so the books reflect reality without manual reconciliation.
What you can sync between Bill and Docusign
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Bill objects | Docusign objects | How this pairing syncs | |
|---|---|---|---|
| Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. | Templates Reusable envelope definitions with predefined recipients and tab placement; read to map fields and referenced by ID to generate new envelopes. | Bank Accounts is specific to Bill and Templates to Docusign — each maps to any object or custom field on the other side. | |
| Vendor Credits and Credit Memos AP and AR adjustments applied against bills and invoices; synced so balances stay accurate on both sides. | Tabs (form fields) Signature, initial, date, text, and checkbox fields on a document; they carry the data a signer entered and are read out into databases. | Vendor Credits and Credit Memos is specific to Bill and Tabs (form fields) to Docusign — each maps to any object or custom field on the other side. | |
| Bills Accounts-payable amounts owed to vendors, with bill line items; read and created via /v3/bills and pulled incrementally by filtering on createdTime/updatedTime. | Envelope Custom Fields Text and list metadata used to tag envelopes for reporting; synced to a warehouse or CRM to key and categorize agreements. | Bills is specific to Bill and Envelope Custom Fields to Docusign — each maps to any object or custom field on the other side. | |
| Vendors Payee master records; synced two-way with vendor/supplier tables in an ERP or accounting system so new payees don't have to be re-keyed. | Folders Containers such as Inbox, Sent, and Draft plus custom folders; listed and moved to organize envelopes and drive reporting queries. | Vendors is specific to Bill and Folders to Docusign — each maps to any object or custom field on the other side. | |
| Invoices Accounts-receivable invoices sent to customers; created and read via /v3/invoices to keep billing status aligned with the ERP or CRM. | Users Account members and senders; the eSignature Users resource exposes them for attribution and reporting, while bulk org-wide user provisioning uses the separate Admin API. | Invoices is specific to Bill and Users to Docusign — each maps to any object or custom field on the other side. | |
| Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. | Envelopes The core container for a signature request — documents, recipients, routing, and status; read status and metadata two-way, and create/send new envelopes. | Customers is specific to Bill and Envelopes to Docusign — each maps to any object or custom field on the other side. |
How changes propagate between Bill and Docusign
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Bill Docusign Sub-second propagation
DetectionBill notifies Stacksync of record changes through webhook events. Webhook event subscriptions (POST /v3/subscriptions) for bills, vendors, payments, invoices, and bank accounts, with polling on.
DeliveryEach detected change is written to Docusign through its API, with automatic retries and rate-limit backoff.
Docusign Bill Sub-second propagation
DetectionDocusign notifies Stacksync of record changes through webhook events. Docusign Connect webhooks push envelope and recipient status-change events in real time.
DeliveryEach detected change is written to Bill through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Bill: 20,000 requests per developer key per hour; login (POST /v3/login) capped at 200/hour; maximum 3 concurrent requests per developer key per organization. Spend & Expense API is a separate token at 60 calls/token/minute.
- Docusign: Default 3,000 API requests per hour per account across all integrations, plus a burst limit of 500 calls per 30-second window; usage is exposed via the RateLimit and BurstLimit response headers.
