Why teams connect E2 Shop System and QuickBooks
Keep QuickBooks and E2 Shop System agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.
E2 Shop System is a read-only source: Stacksync reads its data in real time and delivers it into QuickBooks, so QuickBooks always reflects the current state of E2 Shop System — without exports, scripts, or schedulers.
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.
Common use cases
- 01 Push bills and vendor data from procurement systems into QuickBooks for AP processing.
- 02 Reconcile payment-processor payouts against QuickBooks transactions.
- 03 Keep purchase order data visible to planning or supplier-facing tools without direct ERP access.
- 04 Replicate job and work order status into a reporting database to power shop-floor and delivery dashboards.
Common sync patterns
Where QuickBooks handles billing: invoices land in E2 Shop System
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 E2 Shop System and QuickBooks
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.
| E2 Shop System objects | QuickBooks objects | How this pairing syncs | |
|---|---|---|---|
| Customers Buyer records synced to CRM or accounting counterparts. | Customers Billing entities kept consistent with CRM accounts and subscription tools | Same entity on both sides — records pair one-to-one and field-level changes reconcile in the writable direction. | |
| Vendors Supplier records referenced on purchasing documents. | Vendors Supplier records aligned with purchasing and spend tools | Same entity on both sides — records pair one-to-one and field-level changes reconcile in the writable direction. | |
| Purchase orders Outside material and service purchases tied to jobs. | Purchase orders Procurement documents synced with inventory and ordering systems | Same entity on both sides — records pair one-to-one and field-level changes reconcile in the writable direction. | |
| Invoices Billing records synced to accounting for AR reporting. | Invoices Receivables created from closed deals or orders and read back for payment status | Same entity on both sides — records pair one-to-one and field-level changes reconcile in the writable direction. | |
| Parts Part masters with routings and material definitions specific to each shop. | Items Products and services referenced on invoice and bill lines | Parts is specific to E2 Shop System and Items to QuickBooks — each maps to any object or custom field on the other side. | |
| Routings / Operations Per-part operation sequences that carry estimated and actual times. | Accounts The chart of accounts, mirrored so external postings map to the right ledger lines | Routings / Operations is specific to E2 Shop System and Accounts to QuickBooks — each maps to any object or custom field on the other side. |
How changes propagate between E2 Shop System and QuickBooks
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.
E2 Shop System QuickBooks Interval-based propagation
DetectionStacksync polls E2 Shop System for changes on an incremental schedule, reading only records changed since the previous pass. Polling database tables or scheduled exports.
DeliveryEach detected change is written to QuickBooks through its API, with automatic retries and rate-limit backoff.
QuickBooks E2 Shop System Sub-second propagation
DetectionQuickBooks pushes changes as they happen — webhook events backed by change data capture. Webhooks for entity change events, plus a Change Data Capture query operation for pull-based deltas.
DeliveryE2 Shop System does not accept inbound record writes, so this direction carries requests rather than records: E2 Shop System's output flows back as field updates on the originating QuickBooks records.
Rate-limit considerations
- E2 Shop System: Not API-bound; constrained by on-premises database access windows.
- QuickBooks: Subject to per-realm API request limits.

-
Common patterns for E2 Shop System and QuickBooks: Where QuickBooks handles billing: invoices land in E2 Shop System; 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.
-

-
QuickBooks: Webhooks fire on entity operations including create, update, delete, and merge. E2 Shop System: Installations store data in Microsoft Access or Microsoft SQL Server databases depending on size, which is why integrations typically read the database directly. Stacksync's field mapping accounts for these differences between E2 Shop System and QuickBooks without custom code.
