Event ops teams don’t have a software problem. They have a hand-off problem.
A deal closes in the CRM and someone retypes the event details into LASSO. A project wraps in LASSO and someone retypes the invoice into QuickBooks. The information already exists — it just lives in the wrong system at the wrong time, and someone has to be the human API between the two.
The Zapier integration with LASSO closes those gaps. No engineering ticket. No custom code. No six-week integration project. We just rebuilt the integration with deeper triggers and actions, and it’s live on Zapier now.
Here are the five workflows event production teams build most — two for getting events into LASSO from your CRM, two for getting invoices out of LASSO into your accounting system, and one that opens the door to everything else.
1. Create an Event in LASSO When a Deal Closes in Your CRM
The hand-off this kills: Sales marks a deal “closed-won” in HubSpot or Salesforce, then someone on ops manually creates the matching event in LASSO so production can start staffing it.
What the Zap does: When a deal hits a closed-won (or any qualifying) stage in your CRM, Zapier creates a new event in LASSO with the basics — event name, dates, venue, client, account manager. Ops sees it land in LASSO the same minute sales sees the deal close.
Why it matters: Every day between deal-close and event-creation is a day production isn’t staffing, ordering gear, or building the schedule. When events flow into LASSO automatically, the handoff from sales to ops stops being a meeting and starts being a system. Sales stays in the CRM. Ops stays in LASSO. The deal data lives in both.
2. Update LASSO Events When CRM Details Change
The hand-off this kills: A client moves the date, expands the scope, or swaps the venue, and the update lives in the CRM for three days before ops finds out — usually from an account manager Slack DM.
What the Zap does: When a deal or opportunity updates in your CRM, Zapier pushes the changes to the matching event in LASSO. New dates, venue changes, scope adjustments, account manager changes — they sync automatically using the event’s external code as the link between systems.
Why it matters: The CRM is where client conversations happen. LASSO is where the event gets executed. Keeping them in sync without a person in the middle means production isn’t staffing against last week’s date, and account managers don’t have to remember to email ops every time something shifts.
3. Send LASSO Invoices to QuickBooks Automatically
The hand-off this kills: Accounting manually re-keying invoice data from LASSO into QuickBooks (or Xero, NetSuite, Sage — pick your accounting system) every time a project wraps.
What the Zap does: When a new invoice is sent from LASSO, Zapier creates the matching invoice in your accounting system with the customer, line items, totals, dates, and PO number pre-populated. Your accounting team reviews, your books reconcile, and nothing gets retyped.
Why it matters: Cash flow lives in the gap between “show’s over” and “invoice is out.” Every day you shave off that gap is a day closer to getting paid. And because the invoice is built from LASSO data — not a forwarded email — finance stops chasing PMs for line items that should’ve been right the first time.
4. Sync Payment Status Between LASSO and Your Accounting System
The hand-off this kills: Two systems disagreeing about whether an invoice is paid. PMs chasing clients who already paid. Accounting reconciling the same payment twice.
What the Zap does: Works both directions. If you’re using LASSO Payments, payment status flows from LASSO into your accounting system automatically. If clients pay through your accounting system or a separate processor, paid status flows back into LASSO so PMs and account managers see what’s settled without logging into accounting.
Why it matters: Invoice-to-paid is the messiest data sync in most event companies — and the one with the highest stakes. When LASSO and your accounting system stay aligned automatically, your team stops sending “friendly reminder” emails to clients who already paid, and your weekly AR review takes ten minutes instead of an hour.
5. Build Whatever Else Your Team Needs With the LASSO API on Zapier
The hand-off this kills: Whatever’s slowing your team down. Lead capture from a custom form. Slack alerts when crew confirm. Pushing closed events to your BI tool. Updating a shared Google Calendar so sales doesn’t book a call during load-in.
What the Zap does: The LASSO Zapier app covers the most common workflows out of the box — triggers for new invoices, new payments, and subrentals (purchase orders), plus actions for events, crew, clients, venues, schedule entries, and more. For anything beyond that, the full LASSO API is reachable through Zapier’s Webhooks step — so if it’s in the API, you can build a Zap around it.
Why it matters: The two use cases above are where most teams start. But every event company has its own version of “the thing we keep doing manually that shouldn’t be manual.” Zapier gives your ops team — not your engineering team — the keys to fix it. Build it yourself in fifteen minutes. No engineering ticket required.
