“Sold out” is a strong word to put next to a tour that has two seats left in a wheelchair-accessible row, or a members-only evening that’s simply closed to the public. Yet the availability text that shows up beside an event on an online ticketing page is one of the things Altru administrators have the least say over. People search for how to rename it, find nothing, and assume they missed a setting.
You may not have missed anything. Below is what’s realistic to change, what probably isn’t, and the workarounds that actually get visitors the right message.
What people usually want to change
When someone asks to “change the availability label,” they tend to mean one of these:
- Swap the wording. “Sold out” becomes “Fully booked,” “Waitlist only,” or “Call us for availability.”
- Soften low inventory. Show “Limited availability” or “Almost full” instead of an exact remaining count, or no count at all.
- Explain a closure. A program that isn’t open for online sale (staff-only, members-only, sold through group sales) shouldn’t read as sold out to the public.
- Match your voice. A children’s garden and a historic house museum don’t sound the same, and the default phrasing fits neither.
Be clear about which of these you’re after before you start testing, because the fixes are different.
What Altru gives you on its own
The availability text on Altru’s public-facing ticketing pages is generated by the product, not typed in per event. We aren’t aware of a supported setting that lets you rewrite the “sold out” or “available” wording itself, and we’d rather say that plainly than point you at a menu that may not exist. Blackbaud does change the web experience over time, so confirm against your own version: check the help documentation for your web forms, test in a sandbox if you have one, or ask Blackbaud support directly with a screenshot of the label you want to change.
What you can usually control is the data that drives the label:
- Capacity. The label reacts to the capacity on the event or time slot. If you hold seats back for walk-ups, members, or accessibility needs, the public page will flip to sold out sooner than the room actually fills. That can be the right call, but it’s worth knowing that the label is reflecting a capacity decision, not a headcount.
- Which events are offered online. If an event shouldn’t be sold on the web at all, removing it from the online sale is often cleaner than letting it show as unavailable.
- Event names and descriptions. You fully control these. A line like “Members-only evening; reserve through the membership office” in the description does more than any label could.
Workarounds that hold up
Put the message where you control the words
Most of the confusion a label causes can be headed off on the page around it. Add a short note above the ticketing area: “Times marked sold out may have day-of tickets at the front desk,” or “Accessible seating is held for phone reservations.” Visitors read that context before they read the label.
Use styling only if your setup allows it
Some organizations restyle parts of their online forms with custom CSS. That can change how a label looks (color, size, visibility), but CSS is the wrong tool for changing words, and anything that depends on the page’s internal markup can break quietly when Blackbaud updates the form. If you go this route, document what you changed and recheck it after every Altru update.
Rename the event, not the label
For special cases, a clear event name carries the message: “Sunset Tour (Waitlist)” or “Educator Preview (Invitation Only).” It’s blunt, but it’s reliable, and it shows up in confirmations and reports too, so your staff see it the same way the public does.
Revisit held capacity
If “sold out” keeps appearing on slots that have room, look at how much capacity you’re reserving and why. Sometimes the cleanest fix for a misleading label is releasing seats you no longer need to hold.
Decide what you want to say first
Before changing anything, agree internally on a short vocabulary and use it everywhere: the website, event descriptions, confirmation emails, and what the front desk tells callers. For example:
- Available: tickets can be bought online now.
- Limited: a small number remain; buy soon.
- Sold out online: check at the door or call.
- Not sold online: members, groups, or invitation only, with a contact.
Even if Altru’s own label stays fixed, having this written down keeps your surrounding text consistent and gives you a spec to hand Blackbaud support or any vendor.
When you need full control of the calendar
If the availability wording is genuinely hurting sales or creating calls, the remaining option is to show event availability through a calendar you control rather than the default page. Social Good’s Calendar Builder is an embeddable timed-ticketing calendar for your website that pulls real-time availability from Altru, so the inventory still comes from Altru while the calendar lives on your own site.
Quick answers
Can I hide the remaining ticket count?
It depends on how your online sales are set up, and we can’t promise a switch for it. Test in a sandbox or ask Blackbaud support before telling staff it’s possible.
Why does a slot show sold out when the desk says there’s room?
Usually held or reserved capacity. The public page counts what’s offered online, not every seat in the room.
