Take a part payment and collect the rest later
When someone pays less than the fee, record what they paid. The app keeps the rest as dues on the member, shows it on their page and in your totals, and takes it off when they pay.
Steps
Record the part payment
When renewing (Payments → Record Payment → Renew Membership), or adding a member with Payment at Admission:
Fill the form as usual. Choose the plan, method and date.
In Amount paid now, type what they actually handed over. The line under it says how much will be recorded as dues. Leave it empty if they paid in full.
Tap Renew & Record (or Save Member). The payment shows only the money received, and the member is marked Pending.
Collect the rest
Open the member. An amber box says Dues ₹…. Tap Collect dues.
The payment form opens on Other Payment with Towards dues ticked and the amount filled in. Change the amount if they are paying only part of it.
Tap Record Payment. The dues go down by that amount. When they reach zero, the member is marked Paid again.
You can also start from Payments → Record Payment → Other Payment. Pick the member; if they owe money, a Towards dues box appears under the amount.
Good to know
Seeing who owes: on Members, tap the Has dues filter. Each of those rows shows ₹… due. The dashboard's Outstanding Dues card shows the total and how many members owe it. Tap the card to open that list.
Revenue counts only money received. A ₹2,700 plan paid ₹1,500 now adds ₹1,500 to this month's revenue. The other ₹1,200 counts when it comes in.
You can't collect more than is owed. A payment towards dues larger than the dues is refused. Record the extra as an ordinary payment instead.
A payment that changed dues keeps its amount. If you entered the wrong amount, delete the payment and record it again. Deleting it puts the dues back the way they were.
When it doesn't work
"Amount paid now must be between ₹1 and ₹…" You typed 0, or more than the total. To record nothing yet, untick Record payment now (adding a member) or don't record the renewal until they pay something.
"That is more than the ₹… this member owes." Lower the amount to what is owed, or untick Towards dues.
"This payment changed the member's dues, so its amount cannot be edited." Delete the payment and record it again with the right amount.
The Towards dues box isn't there. That member owes nothing, so there is nothing to put the payment towards.
