QuickBooks Online + HubSpot integration

Largely yes. HubSpot webhooks trigger customer and invoice creation in QuickBooks within seconds, and QuickBooks Online webhooks push invoice and payment changes back to HubSpot as they occur. We add a scheduled reconciliation, typically nightly, to verify balances and recover from any missed events.

We map HubSpot properties to QuickBooks fields, including custom fields, classes and tax codes, and create any missing HubSpot properties. Duplicates are avoided by storing the QuickBooks customer ID on the HubSpot company and matching on domain or email before creating a customer. Errors are logged with the QuickBooks message, retried when transient (rate limits, token refresh) and queued for human review when data is wrong.

Yes. We can build a custom MCP server that exposes both systems so an assistant can list unpaid invoices for a company, summarise recent deals and create a follow-up task in one conversation. Invoice creation can be limited to drafts pending approval.

A standard company, product, deal-to-invoice and payment status sync takes a few weeks including sandbox testing. Additional scope such as multi-currency, multiple QuickBooks companies or HubSpot custom objects for invoices typically extends the project to one to two months.
