Plan Your Day: A Custom Ticketing Workflow on Tessitura’s API That Took Online Sales from 12% to 45%
Mount Vernon’s default Tessitura purchase path was getting the institution roughly 12% of its tickets online. We started from scratch with the Tessitura API and built a custom “Plan Your Day” workflow that walks visitors through date selection, general admission, the timed-entry Mansion tour, specialty add-ons, enhancement items, and discounts — on desktop and on the phone the visitor was already holding. Online ticket share went to 45%, and mobile became Mount Vernon’s single largest sales channel.
The brief
Tessitura is the unified CRM / ticketing / fundraising platform that powers most of the world’s major cultural institutions. Mount Vernon was already running on it when we came in — but the out-of-the-box web purchase path was leaving most of the institution’s ticket sales at the gate. Roughly 12% of tickets were being sold online; the rest of the audience was showing up to the visitor center and standing in line. With foot traffic above a million people a year and a growing share of visitors arriving from a hotel room in D.C. with their phones already out, that ratio was leaving conversion, revenue, and visitor experience all on the table at once.
What we built — the “Plan Your Day” workflow
We started from scratch with the Tessitura API rather than wrapping the standard web purchase path. The result was a guided, step-by-step funnel that treats the ticket purchase as the act of planning a day at Mount Vernon — not just buying a single bar-coded item. Each step is a deliberate decision point, and each step earns the upsell.
Step 1 — Pick the day

Step 2 — General admission

Step 3 — The timed-entry Mansion tour

Step 4 — Specialty tours & add-ons


Step 5 — Enhancement items

Step 6 — Discounts & membership

Why the new workflow works
It treats a ticket as a plan, not an item
The single most important design choice was sequencing. Date first, then admission, then the timed Mansion tour, then specialty tours, then add-ons, then discounts. By the time the visitor sees a Slave Life tour on screen, the system already knows what day they’re coming and what time their Mansion entry is, so it can show only the specialty tours that fit. That’s why the cross-sell works — it’s not a generic upsell card stapled onto the checkout; it’s an offer that actually fits the day the visitor just told us they’re planning.
It was built mobile-first
The biggest insight in the rollout was where the buyers actually were. As Matt put it on the Tessitura case film:
People are coming to Washington, D.C. They’re in their hotel room. They’re looking for things to do, and they’re on their smartphones. Because of what we’ve done with the Tessitura database and the customer API integration, we’ve been able to create a ticketing workflow that allows them to purchase right from their mobile device, and then they can go right up to the gate and scan it. In July 2016, we sold more tickets through our mobile device than any other platform.— Matt Briney, VP New Media, Mount Vernon (Tessitura case study, 2017)
It runs on Tessitura’s API, not Tessitura’s default web purchase path
The platform’s out-of-the-box web purchase path is fine for many institutions. For Mount Vernon — a million-plus visitors a year, dozens of specialty tours, member discount cascades, complex timed-entry inventory across the Mansion and outbuildings — the default flow couldn’t do the upsell math at the speed of the conversation. So we wrote the front end ourselves and pointed it at Tessitura’s APIs for everything: inventory, holds, constituent records, member benefits, fulfillment. That openness is the thing Mount Vernon couldn’t have gotten from any other platform we evaluated.
The results
Three things moved at once:
- Online share of sales went from ~12% to ~45%. Quadrupling the digital channel is the headline result — less line at the gate, better data on every visitor, more capacity at the register for everything that does still happen in person.
- Mobile became the top sales channel. By July 2016, the first full year after launch, the Plan Your Day workflow was selling more tickets via smartphones than any other channel including the gate window itself.
- Specialty tours lifted across the catalog. Tours that had historically under-performed — National Treasure, Slave Life, Distillery & Gristmill, Behind the Scenes — got a much larger share of attention now that they were being offered to visitors who’d already committed to a date and were genuinely planning their day.
What we learned
- Don’t fight your platform; extend it. Building the custom workflow on the Tessitura API meant we kept everything we needed (constituent records, inventory, member benefits, reporting, fulfillment) and only re-built the layer the visitor actually touches.
- The right sequence sells more than the right copy. Showing the specialty tours after the visitor has committed to a date and a Mansion time is what made the upsell work. The order is the offer.
- Mobile isn’t a sidecar. If a third of the people buying tickets are on a phone in their hotel room, the phone is the primary purchase environment — not a stripped-down version of the “real” site. We built the flow to work on the small screen first and let the desktop be a wider version of the same thing.
Why it mattered
It has been a tremendous change. With our previous ticketing system we were only selling about 12% of our tickets online. We now are seeing about 45% of our tickets sold online… The openness of the platform, access to the data that in other systems is really normally very restricted: it’s been a fantastic experience that has allowed us to develop something that really is more tailored toward our business and our customers’ needs.— Matt Briney, Tessitura Success Story, July 2017
The ticketing system isn’t the thing visitors come to Mount Vernon for. But it’s the system the institution sees the visitor through — the door, the cross-sell, the membership upgrade, the renewal, the data trail that feeds everything that comes after. Quadrupling the share of that experience that happens online — and putting it in the visitor’s pocket the day they decide to come — is one of the highest-leverage product moves a place like Mount Vernon can make.
