Why teams connect Bill and TikTok Shop

Keep Bill and TikTok Shop 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 Customers, Payments, Chart of Accounts, Bank Accounts in Bill with Inventory, Returns and refunds, Promotions, Shops in TikTok Shop 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 Sync Customers and Invoices from BILL AR into a CRM or ERP so sales and finance see billing and payment status on the account.
  • 02 Write Vendors created during ERP onboarding into BILL so new payees are ready to pay without manual re-entry.
  • 03 Write tracking numbers and fulfillment status back to TikTok Shop when orders ship
  • 04 Reconcile refunds and returns into accounting systems alongside other sales channels

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 TikTok Shop is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.
