Why teams connect Bill and Nuorder

Turn every Nuorder order into clean revenue: Bill and Nuorder keep customers, orders, and payment status aligned in real time, in both directions.

Nuorder runs the storefront — the catalog, the orders, and the buyers placing them. Bill records the money behind those orders — invoices, revenue, payments, and the ledger the business closes on. The overlap is every customer, order, and product both sides need to agree on, and when that overlap is bridged by CSV export or an overnight batch, finance reconciles against stale numbers while the store quotes prices or stock the books no longer recognize.

Stacksync syncs Payments, Chart of Accounts, Bank Accounts, Vendor Credits and Credit Memos in Bill with Orders, Companies, Line Items, Inventory (ATS) in Nuorder field by field, in real time, and in both directions. You decide which system owns which fields — an order's totals from Nuorder, its paid-or-overdue state from Bill — and Stacksync keeps every copy consistent and resolves conflicts by the rules you set.

The result is one shared record of who bought what and whether it has been paid, so the storefront, support, and the finance team all read from the same current data instead of re-keying it between systems.

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 Sync Inventory / ATS levels from a warehouse or ERP into NuORDER via /api/inventory/{id} so buyers see accurate available-to-sell quantities and oversell drops.
  • 04 Two-way sync Companies (retail accounts) between NuORDER and a CRM so buyers created in either system stay aligned on customer master data.

Common sync patterns

One customer master

Where both systems keep customer or buyer records, an edit in either propagates to the other, ending duplicate accounts and mismatched contact details.

Catalog and pricing stay aligned

Products, SKUs, and prices maintained on one side propagate to the other, so what the store sells and what the ledger books stay in step.

Refunds and credits reconcile

Refunds, cancellations, and credit notes raised in either system update the corresponding record in the other, keeping balances honest on both sides.

What you can sync between Bill and Nuorder

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 Nuorder objects How this pairing syncs
Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. Payments Payment status and detail returned alongside Orders (the modified-orders date-range query returns the order plus its payment information); read-oriented in most syncs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. Orders Wholesale sales orders with nested line items and payment info; read via /api/orders/{status}/detail, created via /api/order/new (PUT), and advanced via /api/order/{id}/process and /cancel. Bank Accounts is specific to Bill and Orders to Nuorder — 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 Retailer and customer accounts (buyers, doors); enumerated via /api/companies/codes/list and created through the customer-creation API, commonly synced with a CRM or ERP. Vendor Credits and Credit Memos is specific to Bill and Companies to Nuorder — 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. Line Items SKU, quantity, and price rows nested inside each Order; the unit ERPs and fulfillment systems consume when an order is written out. Bills is specific to Bill and Line Items to Nuorder — 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. Inventory (ATS) Available-to-sell stock levels updated via /api/inventory/{id} (PUT); usually written from a warehouse or ERP into NuORDER so buyers see accurate availability. Vendors is specific to Bill and Inventory (ATS) to Nuorder — 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. Pricing / Price Lists Wholesale and retail price data attached to products through the product data feeds; read out for margin reporting or written in during catalog loads. Invoices is specific to Bill and Pricing / Price Lists to Nuorder — each maps to any object or custom field on the other side.

How changes propagate between Bill and Nuorder

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 Nuorder 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 Nuorder through its API, with automatic retries and rate-limit backoff.

Nuorder Bill Interval-based propagation

DetectionStacksync polls Nuorder for changes on an incremental schedule, reading only records changed since the previous pass. Polling on modified date: a date-range order endpoint returns the IDs of orders changed within a UTC start/end window.

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.
  • Nuorder: Results are cursor-paginated via lastId/lastValue exposed in a 'next' response header (null on the last page); published request-rate limits are not documented and are governed per integration.
