Why teams connect Bill and Cin7
Keep Bill and Cin7 agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.
A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.
Stacksync syncs Bank Accounts, Vendor Credits and Credit Memos, Bills, Vendors in Bill with Contacts, Branches / locations, Stock adjustments and transfers, Credit notes / returns in Cin7 in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.
Common use cases
- 01 Read Payments and payment status into a reconciliation database once bills are marked paid in BILL.
- 02 Read approved Bills and their line items into a Postgres warehouse for spend, accrual, and cash-flow reporting without CSV exports.
- 03 Consolidate stock movements from multiple branches into one reporting database.
- 04 Publish Cin7 inventory levels to storefronts, marketplaces, and a CRM so every channel quotes real availability.
Common sync patterns
Migration without a hard cutover
When one system is replacing the other, run both in parallel with records matching until the switch is complete.
One customer and vendor master
Where both systems keep records of the same organizations, corrections made in either propagate to the other.
Subsidiary to headquarters
Where Bill serves a business unit and Cin7 is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.
What you can sync between Bill and Cin7
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 | Cin7 objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Products SKU records with options and pricing, synced with storefront and marketplace catalogs. | Vendors is specific to Bill and Products to Cin7 — 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. | Inventory levels Stock on hand by branch or location, published outward for availability. | Invoices is specific to Bill and Inventory levels to Cin7 — 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. | Sales orders Orders captured from all channels; the main object for fulfillment and revenue syncs. | Customers is specific to Bill and Sales orders to Cin7 — 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. | Purchase orders Supplier orders synced with procurement and accounting workflows. | Payments is specific to Bill and Purchase orders to Cin7 — 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. | Contacts Customers and suppliers, matched to CRM records to keep account data consistent. | Chart of Accounts is specific to Bill and Contacts to Cin7 — 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. | Branches / locations Warehouse entities that scope every stock movement and order allocation. | Bank Accounts is specific to Bill and Branches / locations to Cin7 — each maps to any object or custom field on the other side. |
How changes propagate between Bill and Cin7
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 Cin7 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 Cin7 through its API, with automatic retries and rate-limit backoff.
Cin7 Bill Sub-second propagation
DetectionCin7 notifies Stacksync of record changes through webhook events. Polling on modified-date filters.
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.
- Cin7: Subject to per-account API rate limits that differ between Cin7 Omni and Cin7 Core.
