Why teams connect Bill and Nimble
Sync customers, invoices, and payment status between Bill and Nimble in real time, so sales sees the money and finance sees the relationship.
Finance and sales describe the same customers in different systems. Nimble knows the relationship: who the contacts are and what is in motion with the account. Bill knows the money: what was invoiced, what was paid, what is overdue. When the two are connected only by exports, each side works partly blind.
Stacksync links Payments, Chart of Accounts, Bank Accounts, Vendor Credits and Credit Memos in Bill to Notes, Tags, Custom fields, Contacts in Nimble with bi-directional, real-time sync. New customers, updated billing details, invoice status, and payment activity move in whichever direction you configure, field by field, with conflicts resolved by rules you set. The result is one version of each customer, visible from both sides.
Common use cases
- 01 Write Vendors created during ERP onboarding into BILL so new payees are ready to pay without manual re-entry.
- 02 Read Payments and payment status into a reconciliation database once bills are marked paid in BILL.
- 03 Push product usage or billing flags from internal databases into Nimble custom fields so reps have context before outreach.
- 04 Keep deals aligned between Nimble and an accounting system so invoicing starts when a deal closes.
Common sync patterns
Billing detail changes flow back
When a contact or address is corrected in Nimble, Bill gets the update before the next invoice goes out.
Collections with context
Finance sees the account owner and relationship history from Nimble when chasing a balance, and sales sees that the chase is happening.
Where Nimble tracks deals: closed-won creates the finance record
A won opportunity creates or updates the customer in Bill with the right billing details, so invoicing starts without re-keying.
What you can sync between Bill and Nimble
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 | Nimble objects | How this pairing syncs | |
|---|---|---|---|
| Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. | Notes Free-text records attached to contacts, replicated for a complete account timeline | Customers is specific to Bill and Notes to Nimble — each maps to any object or custom field on the other side. | |
| Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. | Tags Segmentation labels that map to list membership or filters in downstream systems | Payments is specific to Bill and Tags to Nimble — each maps to any object or custom field on the other side. | |
| Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. | Custom fields Account-defined contact attributes that carry enrichment or internal identifiers | Chart of Accounts is specific to Bill and Custom fields to Nimble — each maps to any object or custom field on the other side. | |
| Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. | Contacts Person records with multi-value fields for email, phone, and social profiles; the primary sync entity | Bank Accounts is specific to Bill and Contacts to Nimble — 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. | Companies Stored as contact records with a company record type, so they sync through the same contacts resource | Vendor Credits and Credit Memos is specific to Bill and Companies to Nimble — 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. | Deals Pipeline records linked to contacts, synced to keep revenue systems aligned with sales activity | Bills is specific to Bill and Deals to Nimble — each maps to any object or custom field on the other side. |
How changes propagate between Bill and Nimble
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 Nimble 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 Nimble through its API, with automatic retries and rate-limit backoff.
Nimble Bill Interval-based propagation
DetectionStacksync polls Nimble for changes on an incremental schedule, reading only records changed since the previous pass. Polling on record modification timestamps.
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.
- Nimble: Subject to per-account API request quotas.

FAQ
Bill and Nimble integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bill and Nimble: authenticate both systems, choose the objects to sync (such as Bill's Customers and Payments), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Bill: List endpoints support filtering and sorting on createdTime and updatedTime with ISO 8601 date-time ranges, which sync engines use to pull only incremental changes. Nimble: Nimble stores people and companies as contact records distinguished by record type, so both entity types flow through the same contacts resource. Stacksync's field mapping accounts for these differences between Bill and Nimble without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Bill and Nimble records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Bill and Nimble connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Bill–Nimble integration in-house.
