Linking Siblings to a Family Account
Siblings are linked automatically by matching parent phone numbers when a student is added — but Fees101 won't auto-link two students into one family on a name mismatch alone, since that's exactly how discount abuse happens.
How the automatic matching works
When you add a student, their parent's phone number is normalized (0803…, +234803…, and 234803… are treated as the same number) and checked against every existing family on file. If it matches an existing family and the parent name also matches, the new student is linked to that family automatically — no extra step.
Moving credit between siblings
If one sibling has unapplied credit on their account and another sibling in the same family has an open invoice, use Reallocate Family Credit from the student profile to move it across. The move is atomic, applies automatically to the recipient's open invoice, and notifies the parent. See How Credit Balance Works for where this credit actually comes from in the first place.
