Why teams connect Bill and QAD ERP
Keep Bill and QAD ERP 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 Vendor Credits and Credit Memos, Bills, Vendors, Invoices in Bill with Sales orders, Purchase orders, Work orders, Inventory balances in QAD ERP 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 data from multiple QAD instances, per plant or region, into one reporting database.
- 04 Sync items, customers, and orders between QAD and a CRM so sales teams work outside ERP screens.
Common sync patterns
Where Bill handles billing: invoices land in QAD ERP
Invoices and payment activity from the billing side post through to the enterprise system automatically.
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.
What you can sync between Bill and QAD ERP
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 | QAD ERP 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. | Customers Account records kept consistent with the sales team's CRM | 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. | General ledger transactions Financial postings exported for consolidated reporting | Bank Accounts is specific to Bill and General ledger transactions to QAD ERP — 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. | Items Item master records shared with CRM, e-commerce, and planning systems | Vendor Credits and Credit Memos is specific to Bill and Items to QAD ERP — 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. | Suppliers Vendor master data aligned with procurement and AP automation tools | Bills is specific to Bill and Suppliers to QAD ERP — 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. | Sales orders Demand records written in from EDI or e-commerce and read out for status | Vendors is specific to Bill and Sales orders to QAD ERP — 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. | Purchase orders Procurement documents mirrored to planning and finance systems | Invoices is specific to Bill and Purchase orders to QAD ERP — each maps to any object or custom field on the other side. |
How changes propagate between Bill and QAD ERP
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 QAD ERP 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 QAD ERP through its API, with automatic retries and rate-limit backoff.
QAD ERP Bill Interval-based propagation
DetectionStacksync polls QAD ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on the API surface.
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.
- QAD ERP: Subject to instance capacity and the platform's API limits.

-
Common patterns for Bill and QAD ERP: Where Bill handles billing: invoices land in QAD ERP; Migration without a hard cutover; One customer and vendor master. Invoices and payment activity from the billing side post through to the enterprise system automatically.

Bill: Webhook event subscriptions are limited to up to 10 per organization and cover bills, vendors, payments, invoices, and bank accounts; Spend & Expense webhooks run only in the production environment. QAD ERP: QXtend, QAD's integration framework, exchanges XML business documents (QDocs) for transactions such as orders and receipts. Stacksync's field mapping accounts for these differences between Bill and QAD ERP without custom code.
