A supporter mails a check for $120 with a note that says “for our family membership.” It gets entered as a donation. Three weeks later they call to ask where their membership cards are. Now you have a gift in Altru that should have been a membership payment, and there isn’t one obvious “convert” action that does the whole job for you.
The fix depends less on the mistake itself and more on how far that payment has traveled since it was entered. Work out where it is first, then pick the approach that matches.
First, answer three questions about the payment
- Has the batch been committed? A payment still sitting in an uncommitted batch is just a row you can correct. Once committed, it is a revenue record, and changes have to happen on that record.
- Has it posted to the general ledger? If your finance team has already posted the period, any change becomes an adjustment that finance will see. Talk to them before you touch it.
- Has the donor already been acknowledged? A thank-you letter or tax receipt that called the full amount a charitable gift is now wrong, because membership benefits can reduce the deductible portion. That letter may need to be replaced.
Write those three answers on the ticket before you start. They decide everything below.
Option 1: The batch isn’t committed yet
This is the easy case. Correct the row in the batch so the payment applies to a membership instead of a donation, with the right membership program, level, and term. How the batch row exposes that choice depends on your batch template, so check with whoever set up your batches if the option isn’t where you expect. Then commit the batch normally. Nothing has posted, nothing has been acknowledged, and the revenue record is created correctly the first time.
That’s why a daily review of open batches pays off. Most donation-versus-membership mix-ups are obvious to a second set of eyes if someone looks before committing.
Option 2: Committed, but not posted
Altru lets you edit an existing payment’s application in some situations, but whether you can move a committed payment from a donation to a membership directly depends on your version, your security rights, and the state of the record. We’d rather not promise a specific path here. Before attempting it on a live record, try it in a sandbox or a test constituent, or ask Blackbaud support how they recommend handling it in your environment.
If a direct edit isn’t available, the common approach is a clean reverse-and-reenter:
- Note the original payment date, amount, payment method, and any check number.
- Remove or reverse the donation according to your organization’s normal process for incorrectly entered gifts (this is often a delete if nothing has posted, or an adjustment if it has).
- Enter a new membership transaction for the same amount, using the original payment date so the membership term and your revenue reports reflect when the money actually came in.
- Add a note on the constituent record and the new revenue record explaining what happened and referencing the original entry.
Keeping the original date matters. If you enter the new membership with today’s date, the term may start weeks late, and your monthly revenue totals will show the money landing in the wrong period.
Option 3: Already posted to the GL
Stop and involve finance. Moving posted revenue from a contribution account to a membership account is an accounting change, not just a data cleanup. Your finance lead may want the adjustment posted in the current period, or may want it handled at month-end with other corrections. Follow their call, then do the Altru side of the work so the constituent’s record matches what they paid for.
Don’t forget the downstream pieces
Getting the revenue record right is only half the job. Check each of these before you close the ticket:
- Membership dates. Confirm the start and expiration dates make sense from the original payment date, not from the day you fixed it.
- Household and add-on members. A family level may need the spouse or other members attached, or cards print with one name.
- Cards and welcome materials. Make sure the new membership lands in whatever process produces cards or a welcome email.
- Acknowledgments. If a donation receipt already went out, send a corrected membership acknowledgment. Be careful that the original letter doesn’t get re-sent by a later acknowledgment run.
- Appeals and solicitations. If the gift was tied to an appeal, the appeal’s results will drop. That’s correct, but warn whoever reports on it.
When the supporter meant both
Sometimes the check really is part membership, part gift: $200 from someone whose level costs $120. In that case, the goal is for $120 to apply to the membership and $80 to stay a donation. Altru generally lets one payment be applied to more than one purpose at entry; if you aren’t sure how your batch template handles it, test it on a sample record first. Splitting at entry is much easier than splitting after the fact, so it’s worth training whoever opens the mail to look for these and flag them.
Keeping it from happening again
The same handful of sources cause most of these corrections:
- Mailed checks with vague notes. Give gift processors a simple rule: if the amount matches a membership level, or the note says “member,” hold it for a quick check before entering it as a donation.
- Online forms that look alike. If your donation page and membership page share layout and wording, people pick the wrong one. Make the membership page plainly about benefits and levels, and link to it from the donation page.
- Phone and desk staff. A one-line question (“Is this for a membership, or a gift on top of one?”) prevents most mistakes at the point of sale.
- A weekly query. Build a revenue query for donations in the last week whose amounts match your membership level prices. It won’t catch everything, but it surfaces the likely mix-ups while they’re still easy to fix.
Quick answers
Can I just change the revenue type on the record?
Sometimes, depending on the record’s status and your permissions. Test it in a sandbox or confirm with Blackbaud support before relying on it, and check that the membership itself is created, not just the label on the payment.
Will the donor lose their tax receipt?
Their original receipt is likely overstated once benefits are involved. Send a corrected acknowledgment that reflects the membership and any portion that remains a gift.
