The problem this solves
The same transaction gets entered twice: once when sales closes it in HubSpot, again when finance keys it into the accounting system, and the two never quite match. Revenue recognized in one place is invisible in the other, reconciliation is a monthly manual grind, and a Polish business also has KSeF e-invoicing obligations that HubSpot does not handle on its own. Every manual re-key is a chance for the numbers to drift apart.
How we work
We map the quote-to-cash flow across both systems first: what event in HubSpot should create or update what in accounting, which system owns which field, and where the source of truth sits for each stage. That map is the real deliverable - without it, an integration just syncs confusion faster.
Then we build the connections: quotes, invoices, payments, and subscription events flowing to your accounting or ERP system, and the automation that removes the manual handoffs between sales closing a deal and finance recognizing it. For Polish businesses this is also where KSeF e-invoicing and local connectors - Fakturownia, Symfonia, wFirma, and similar - come into scope, since national e-invoicing is a legal requirement HubSpot does not cover natively.
Integration is where we are strongest and most careful. We build for production, not demo: idempotency on writes so a retry never double-posts a payment, backoff on transient failures, and alerting with a runbook so a broken sync is caught by monitoring rather than by finance at month-end. A revenue integration that fails silently is worse than no integration.
Deliverables
- Quote-to-cash flow mapped across HubSpot and finance systems
- Sync of quotes, invoices, payments, and subscriptions to accounting or ERP
- KSeF e-invoicing and Polish connectors where required
- Automated handoffs that remove manual re-keying
- Idempotent writes, backoff, and failure alerting with a runbook
- Documented source-of-truth rules per field and stage
What buyers ask before scoping.
Does HubSpot handle Polish KSeF e-invoicing on its own?
No - KSeF is a national e-invoicing obligation and HubSpot does not cover it natively, so it needs an integration path. This module is where that gets built, connecting HubSpot's commerce data to KSeF and to Polish tools like Fakturownia, Symfonia, or wFirma as your setup requires. We have built Polish-market connectors before and treat compliance obligations as a hard requirement, not a nice-to-have.
Which accounting or ERP systems can you integrate with?
Where a solid native or well-supported connector exists, we use it; where it does not, we build against the accounting or ERP system's API directly, which is core to how we work across the wider stack. During scoping we assess your specific system and tell you honestly whether it is a connector job or a custom build, and what each path means for time and durability.
How do you keep the sync from double-posting or silently breaking?
By building it as a production integration rather than a happy-path script. Idempotency keys on writes mean a retry cannot post the same payment twice, exponential backoff handles transient API failures, and alerting plus a runbook means a broken sync is caught by monitoring rather than by finance finding a gap at month-end. Financial data is exactly where silent failure is most expensive, so we engineer against it deliberately.
