INTEGRATION

QuickBooks + HubSpot: answers that need both systems

SIGNLD reads QuickBooks and HubSpot, joins them in the Knowledge Graph, and answers questions that neither system can answer alone. It is read-only. It does not sync records between the two and it never writes to either system.

Entity resolution matches each HubSpot company to its QuickBooks customer, so one customer is one entity even when the two systems spell the name differently. SIGNLD proposes the match and you confirm or correct it once.

Questions you can ask

Which closed-won deals from last quarter still have unpaid invoices?
What is revenue collected, not just booked, by sales rep?
Which customers have the longest gap between deal close and first payment?
Which lead sources produce customers who pay on time?
What is the real margin on deals that needed discounts?
Which accounts are growing in HubSpot activity but shrinking in invoices?
How does average days-to-pay differ by deal owner?
Which renewals are coming up for customers with overdue balances?

How it is different from a sync tool

Sync connector, spreadsheet export and SIGNLD compared
	Sync connector	Spreadsheet export	SIGNLD
What it does	Copies records between QuickBooks and HubSpot on a schedule.	Exports each system to a file that someone joins by hand.	Reads both systems, joins them in the Knowledge Graph and answers questions with sources.
Writes to your systems?	Yes. It creates and updates records in one or both systems.	No, but the export goes stale as soon as it is saved.	No. Read-only access. Nothing is written back.
Answers cross-system questions?	No. It moves data. Reporting still happens elsewhere.	Only after manual matching, and only for the snapshot exported.	Yes. Questions that need both systems return a Decision Brief with lineage.

Questions

Does SIGNLD change anything in QuickBooks or HubSpot?

No. Both connections use read-only access. SIGNLD reads records, joins them in the Knowledge Graph and writes nothing back to either system.

Does it work with QuickBooks Desktop or only QuickBooks Online?

The QuickBooks connector authenticates with QuickBooks OAuth, which is QuickBooks Online. QuickBooks Desktop data can be brought in through manual upload of exported files.

How often does the data refresh?

Refresh cadence follows your plan. Free Forever is manual at weekly maximum, Plus is scheduled, and Growth and above refresh daily. You can also trigger a manual sync at 1 credit per source per run.

What does it cost?

Free Forever is manual upload only. Live QuickBooks and HubSpot connectors run on paid plans starting with Plus at $25 per month, and the 14-day Growth trial includes them with no credit card.

Can I add other systems later?

Yes. SIGNLD connects to 800+ systems. Each new source joins the same Knowledge Graph, so later questions can span QuickBooks, HubSpot and anything you add.
