A donor commits $5,000 over two years, paid quarterly. The pledge is in Altru, the reminder letter goes out, and the donor writes back: “Can I just pay this online?” It’s a fair question, and it’s where a lot of development offices discover a gap between taking a gift and taking a payment on a gift that already exists.
Those are different things in Altru. A new online donation creates new revenue. A pledge payment has to be applied against an open pledge balance so the commitment goes down, the installment schedule stays accurate, and nobody gets credited twice. Getting the money online is the easy part. Getting it attached to the right pledge is the part that needs a plan.
The core problem: a gift form doesn’t know about the pledge
A standard donation web form is built for new giving. The donor picks an amount, pays, and Altru records a payment. Unless the form is specifically set up to look up and apply to an existing commitment, that payment lands as its own gift, separate from the pledge.
When that happens, you get the usual downstream mess:
- The pledge still shows the full balance, so the next reminder goes out for money already received.
- Giving totals for the donor look inflated, because the payment and the pledge are both counted.
- Finance sees revenue that doesn’t line up with the pledge schedule they’re tracking.
- Someone has to find the stray gift, reverse or adjust it, and reapply it to the pledge by hand.
Whether your version of Altru’s online forms can apply a payment directly to an existing pledge is worth confirming rather than assuming. Test it in a sandbox with a dummy constituent and a small pledge, or ask Blackbaud support how your forms handle pledge payments. If the answer is “it creates a new gift,” you’ll need one of the approaches below.
Three workable approaches
1. Online payment, staff apply it to the pledge
The donor pays through any online form you already use, and a staff member applies the payment to the pledge in Altru. It’s the simplest setup and works fine at low volume.
To keep it under control:
- Use a dedicated designation, appeal, or form just for pledge payments so these gifts are easy to pick out.
- Ask the donor for the pledge or reference number on the form, even as a free-text field.
- Build a query that pulls recent payments from that source, and review it on a fixed schedule (weekly is typical) so nothing sits unapplied through a reminder cycle.
- Decide who owns the step. Pledge payments that “someone will apply” tend to wait until month-end reconciliation.
2. Send the donor a specific payment link
Instead of pointing donors to a general giving page, send each one a link tied to their payment: the amount due, what it’s for, and who it’s from. This is closer to how an invoice works, and it removes most of the guesswork about which pledge a payment belongs to, because you created the request with that pledge in mind.
It also changes the donor’s experience. “Pay your Q3 installment of $625” is clearer than “Give now,” and it doesn’t invite them to type in a different amount by accident.
3. Keep pledges on recurring or scheduled payments
For donors who are comfortable with it, charging installments automatically avoids the “please pay online” step entirely. How well Altru handles stored-card or scheduled charges against a pledge depends on your payment processor and setup, so confirm it in a sandbox or with Blackbaud support before promising it to donors. It also isn’t right for every major donor; some prefer to approve each payment. For steady multi-year commitments, though, it cuts down on manual touches.
Things to settle before you open the door
Whichever route you pick, a few decisions make the difference between a tidy pledge ledger and a cleanup project:
- Overpayments and underpayments. If a donor pays more than the installment, does the extra go to the next installment, the pledge balance, or a new gift? Write it down.
- Paying off early. Some donors will want to clear the whole balance. Make sure staff know how to apply a payment that covers several installments.
- Acknowledgments. A pledge payment receipt should reference the pledge and remaining balance, not read like a thank-you for a new gift. Check which letter or email template fires for these.
- Batching and deposits. Online payments usually come through your processor in a deposit that mixes ticket sales, memberships, and gifts. Know how pledge payments will be separated out when finance reconciles.
- Reminders. Pull pledge reminders from a query that checks current balances right before they go out, so a donor who paid yesterday doesn’t get a past-due notice today.
How to tell whether it’s working
Run a simple check each month: payments received from your pledge-payment source compared with payments applied to pledges in the same period. If those numbers match, your process is holding. If there’s a gap, it’s almost always payments recorded as standalone gifts that never got reapplied, and the sooner you catch them, the easier they are to fix.
Where Social Good can help
If sending donors a specific link to pay is the approach you want, Link2Pay is our branded pay-by-link tool for pledges, invoices, deposits, and group sales. You send the donor a link for the amount due, they pay online, and the payment posts to Altru. You’ll still want the review query and written policies above, but the donor gets a clear, specific payment request instead of a general giving page.
Quick answers
Can a donor just use our regular donation page to pay a pledge?
They can pay, but unless the form applies payments to existing pledges, you’ll get a separate gift that staff need to move onto the pledge. Confirm how your forms behave before relying on them.
What if a payment was already recorded as a new gift?
Adjust it so it’s applied to the pledge, and add a note on the record explaining the change. Do it before the next reminder run so the donor isn’t asked for money they’ve already sent.
