Why teams connect Hyperline and Lemlist
Connect the financial records in Hyperline with the work happening in Lemlist, so both stay current without exports or copy-paste.
Hyperline holds the financial truth: who the customers are, what they were billed, what they paid. Lemlist is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.
Stacksync keeps Products / prices, Invoices, Payments, Billable events in Hyperline and Leads, Activities, Unsubscribes, Webhooks in Lemlist in sync, bi-directionally and in real time. Whatever records Lemlist keeps and whatever events it produces, the overlap with Hyperline is mapped field by field, and a change on either side shows up on the other within seconds.
There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.
Common use cases
- Sync invoices and payments into a data warehouse or accounting system for revenue reporting and reconciliation.
- Keep plan and entitlement state consistent between Hyperline and the application database that enforces feature access.
- Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
- Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
Where Lemlist is a docs or knowledge workspace: reference data kept fresh
Figures teams rely on, like customer status or outstanding balances, stay current wherever Lemlist surfaces them instead of going stale after a one-time paste.
Where Lemlist handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Hyperline next to the customer they are helping, without logging into the finance system.
Where Lemlist collects payments or triggers charges: events land in Hyperline
Payment and charge activity flows into Hyperline as it happens, so the books reflect reality without manual reconciliation.
What you can sync between Hyperline and Lemlist
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Hyperline objects | Lemlist objects | |
|---|---|---|
| Payments Settlement records used to reconcile revenue against invoices. | Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | |
| Billable events Metered consumption events ingested to drive usage-based charges. | Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | |
| Credit notes Adjustments and refunds synced for accurate revenue reporting. | Team Members Sender and seat records map outreach activity to reps in other systems. | |
| Customers Billing accounts that syncs match against CRM and product records. | Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | |
| Subscriptions Active plans and their lifecycle state, synced to show billing status elsewhere. | Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | |

-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Hyperline and Lemlist connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Hyperline–Lemlist integration in-house.
