HubSpot already has a QuickBooks Online integration available, and for many companies it is the right place to start: try it first. The reason this page exists is the companies that tried it and still re-key. Their deals carry several product lines with different income accounts, their invoices follow a billing schedule rather than a single close date, they invoice from more than one legal entity, or they need to decide in HubSpot which deals are billable at all. At that point the question becomes one of mapping, and mapping is what we build.

Meanwhile the symptoms are the same everywhere: finance asks sales for the details of a closed deal, sales asks finance whether an invoice has been paid, and the customer's address is different in the two systems.

What ECOSIRE builds

A custom integration between HubSpot and QuickBooks Online, built on the HubSpot CRM API (with a private app and the scopes it needs) and the QuickBooks Online Accounting API (OAuth 2.0). Scope is set by your pipeline, not by a template.

Company and contact to customer, matched deliberately

Each HubSpot Company is paired with a QuickBooks Customer by a key chosen in scoping, never by name alone, and the pairing is kept as a property on the company and a reference on the customer. Anything unclear is held for a person to review. Billing addresses, terms and tax treatment are mapped so an invoice is correct the first time.

Closed-won deals to invoices, on your rules

A deal reaching the stage you name, and passing the checks you define (a billable flag, a complete billing address, a customer match), creates an invoice in QuickBooks Online. Line items on the deal are mapped to QuickBooks Items and income accounts. Billing schedules, such as deposits, instalments and recurring periods, are created from deal properties. You decide whether finance receives a draft or a sent document; either way the invoice carries the HubSpot deal reference.

Multiple entities and classes

Where you invoice from more than one QuickBooks company, or use classes and locations, the deal's properties choose the target, with a rule for the case where they are missing, rather than a default that quietly posts to the wrong books.

Payment status back to the deal

The invoice number and its status, balance, due date and receipts are written into deal properties or a custom object in HubSpot, so the deal itself shows whether it has been paid, and HubSpot workflows can respond to a late or settled invoice.

A log you can read

Every sync action is logged with its outcome where an administrator can read it, and a single failed record can be retried on its own. Webhook subscriptions or workflow actions start the work, depending on your HubSpot subscription tier, and a scheduled reconciliation picks up anything missed.

Who this is for

Companies selling through HubSpot with their books in QuickBooks Online, whose billing goes beyond what a standard connector handles: several product lines, instalments, more than one entity or a billable-deal rule. If a standard connector fits, use it.

How delivery works

1. Mapping review. We look at your pipeline, deal properties, QuickBooks items, accounts and entities, and at what the standard connector left you doing by hand. 2. Quote. You receive a written scope with exclusions, assumptions and a delivery date, and nothing is built until you accept it. 3. Test-account build. Everything is built against a HubSpot test or developer account and a QuickBooks Online sandbox company. 4. Dry run. Customers and items are reconciled first, then a batch of your real deals is run through to draft invoices for you to inspect. 5. Production. Sync goes live and we are on hand for your first billing cycle.

What this is not

It is not a second copy of the standard connector and it is not a download. The build covers only the mapping gaps we find together in scoping, against a written quote with scope, exclusions and a delivery date. Your accountant still owns accounting policy. It targets QuickBooks Online; QuickBooks Desktop is a different integration path and is scoped on its own.
