A summer pass for local families. A three-month membership for visiting researchers. A month-to-month option for people who balk at a full year up front. Each one sounds simple until you sit down to build it in Altru, where the membership setup assumes, by default, that people join for a year and renew for a year.
Short-term memberships are doable. The harder part is deciding what kind of thing you are actually selling, because that choice affects your renewal mail, your retention numbers, and what the front desk sees when a summer member walks in on Labor Day. Settle that before you touch configuration.
First, name what you are selling
“Summer membership” can mean three very different products:
- A true short membership. Member benefits, member pricing, a card, and an end date a few months out. You want these people counted as members and invited to upgrade.
- A seasonal pass. Unlimited visits from Memorial Day to Labor Day, maybe a discount at the shop, but you don’t really think of these buyers as members and don’t want them in your membership totals.
- An annual membership paid monthly. The member gets a full year; only the payment is spread out. This is a payment question, not a term question.
Each one points to a different setup in Altru. Mixing them up is how you end up with a “member” count that swings wildly every September.
Option 1: A short-term level or program
If you want real members on a short term, the path is a membership level (or a separate membership program) whose term is shorter than a year. Membership programs in Altru define the levels, prices, benefits, and the term each level runs. Whether your setup lets you choose a term in months, and which month lengths are available, is something to confirm in your own database. Build a test level in your sandbox, sell one, and look at the expiration date it produces before you put anything on the website.
A few decisions to make while you test:
- Separate program or same program? Keeping summer members in their own program makes them easy to exclude from annual retention reports and renewal mailings. Putting them in your main program makes an upgrade to a full membership feel like a natural step up. Many organizations choose a separate program for reporting clarity.
- Rolling term or fixed end date? “Three months from purchase” and “valid through Labor Day” behave very differently. If you sell a summer product in June and in August, a rolling term means August buyers carry their membership into November. If you want a hard end date, check whether your program configuration supports it; if it doesn’t, a seasonal pass (Option 2) may be the better fit.
- Renewal behavior. Decide whether a summer member should ever get a renewal notice. Usually the answer is no: you want them to get an upgrade offer instead. Make sure your renewal queries and mailings exclude the short-term level or program.
- Upgrade credit. If a summer member converts to an annual membership in August, do they get credit for what they paid? Write the rule down so staff aren’t improvising. How Altru handles an upgrade between programs versus within a program is worth testing in the sandbox, because it affects whether the history looks continuous.
Option 2: A seasonal pass that isn’t a membership
If you mostly want “unlimited visits this summer,” you may not need a membership at all. Some organizations sell this as a ticket or pass product rather than a membership level, then track buyers with a constituent attribute or a query so they can be marketed to later.
The tradeoff is real. You keep your membership numbers clean, but pass holders won’t automatically get member benefits, member pricing, or a membership card, and admission staff need a clear way to verify them at the door. If repeat entry is the whole point, test how your daily sales process will recognize a pass holder on their fifth visit before launch. If you can’t find a clean way to do it, that’s a sign the membership route is the better fit.
Option 3: Annual membership, monthly payments
When people ask for a “monthly membership,” they often mean a lower monthly price, not a shorter commitment. In that case, keep the standard annual level and look at whether you can take the payment in installments or as a recurring payment. Confirm exactly what Altru supports for membership installments and recurring payments in your configuration, especially for web sales, by checking with Blackbaud support or testing in your sandbox. Payment options can differ between what staff can do at the desk and what your online forms offer.
Also decide what happens when a monthly payment fails. Does the membership stay active through the year, or lapse? The policy matters more than the setting, and members will ask.
Reporting traps to plan for
- Retention rates. Short-term members who don’t renew will drag your renewal rate down if they’re in the same program as annual members. Exclude them or report them separately.
- Member counts. A summer level inflates your total in July and deflates it in October. Board reports should either break it out or use a consistent snapshot date.
- Lapsed lists. Every summer member becomes “lapsed” in the fall. Filter them out of lapsed-member appeals, or write a separate upgrade message for them.
- Revenue coding. Decide whether seasonal revenue rolls up with membership or with admissions, and set designations or revenue categories to match before the first sale.
A sensible rollout
- Decide which of the three products you are really offering.
- Build it in your sandbox and sell a few test transactions: at the desk, online if applicable, and an upgrade to annual.
- Check the expiration dates, the constituent record, and how the sale shows up in your membership and revenue reports.
- Update renewal and lapsed queries to exclude the new level or program.
- Brief front desk staff on how to sell it, how to verify it at entry, and what to say when someone asks to upgrade.
- Schedule an end-of-season review: how many converted to annual, and was the price right?
Quick answers
Can a summer membership end on a fixed date regardless of when it’s bought?
That depends on how your membership program terms are configured. Test it in a sandbox; if a fixed end date isn’t possible, consider pricing the product down as the season goes on or selling it as a seasonal pass.
Should short-term members get renewal notices?
Usually not. An upgrade offer toward the end of their term tends to make more sense than asking them to buy another short term.
