The problem with running two sites on one system
A school that opens a second site usually ends up with two of everything: two spreadsheets, two fee registers, two versions of the truth. The alternative most systems offer is worse — run each site as a completely separate school, and the head office loses any view across them.
Edunile treats your campuses as what they are: parts of one school. You add each site once, and from then on every class, every staff member and every student is attached to one. Nothing is duplicated, and nothing has to be reconciled between two systems at the end of term.
Work in one site, or all of them
Rosters, records, reports and messages can all be filtered by campus. A head of campus pulls up their own students; a bursar filters collection down to their site; the proprietor takes the filter off and sees the whole school.
Because it is one school, the things that should be shared are shared — your academic sessions and terms, your fee heads, your branding, your communication templates. You set them once rather than keeping two sets in step.
Fees and collection, site by site
Fee heads are defined once for the whole school — tuition, boarding, development levy, PTA levy — so a parent at either site receives an invoice that reads the same way and breaks down into the same named lines. What changes is the view: your bursar can narrow the collection dashboard to a single campus and see exactly what that site has brought in and what is still outstanding, then widen it again for the board pack.
That matters most in the first weeks of a term, when the question is never "how much have we collected" in the abstract. It is "how far behind is the annex", and answering it should not require exporting two spreadsheets and adding them up.
Moving a student between sites
A student who moves from one of your campuses to another keeps the same record. Their academic history, fee history and admission number travel with them, because they never left the school — only the site changed. There is no transfer-out and re-admit, no new admission number, and no gap in their results.
The same applies to staff. A teacher who covers classes at both sites is one person on your roster, not two accounts to keep in step.
