BigCommerce Sage Integration: Automated Accounting for BigCommerce Merchants
UK-based and mid-market BigCommerce merchants using Sage need their eCommerce transactions to flow into Sage accurately — with the right VAT codes, customer accounts, and nominal ledger postings — without hours of manual data entry per week. SyncTools automates that entire flow from BigCommerce to Sage.
TL;DR: SyncTools connects BigCommerce to Sage (50, 200, or Intacct) — creating properly coded Sage invoices, credit notes, and expense entries from BigCommerce orders, refunds, and payment fees. UK VAT coding is handled correctly so your VAT return is accurate on first draft. Free 30-day trial, no credit card required.
The BigCommerce Sage Accounting Challenge
BigCommerce generates invoices, refunds, fee charges, and payout deposits across multiple payment gateways and potentially multiple storefronts. Getting all of that into Sage with correct nominal codes, tax rates, and customer records is error-prone when done manually — and the errors accumulate quickly in a high-volume store.
SyncTools reads BigCommerce transaction data and creates the correct Sage records automatically, following the structure your Sage accountant expects.
What SyncTools Syncs from BigCommerce to Sage
- Sales invoices — BigCommerce orders as Sage sales invoices linked to customer accounts
- Credit notes — refunds as Sage credit notes against the original invoice
- Purchase invoices — payment gateway fees as Sage purchase invoices against an expense nominal
- Bank payments — payout deposits matched to Sage bank transactions
- VAT / GST / sales tax — mapped to Sage tax codes for accurate VAT returns
- Shipping income — separated from product revenue in your Sage nominal ledger
- COGS — cost-of-goods synced for gross margin reporting in Sage

Why Sage Users Choose SyncTools for BigCommerce
Sage users, particularly in the UK market, need accounting integrations that respect Sage’s nominal code structure and VAT coding requirements. Generic eCommerce connectors often create journal entries that bypass Sage’s sales and purchase ledgers — creating reconciliation problems that take accountants hours to unwind.
SyncTools creates proper Sage sales invoices, purchase invoices, and credit notes, keeping your ledgers balanced and your VAT return accurate.
