Ask a tutoring centre owner how the business is doing and the answer is usually about the diary: full, nearly full, a tutor short. Ask to see the bank account and the picture is different — sessions taught in March invoiced in April and paid in June, a family six weeks behind who is still attending, a tutor paid for an hour a student did not attend and nobody charged. The diary says the business is healthy. The receivables say it is lending money to its customers at zero interest and calling the result cash flow.
Billing is where a tutoring business leaks because the unit is small, the volume is high, and the thing being billed happened in a room the payer never saw. An invoice for eight sessions depends on the diary being right, the cancellations recorded against the policy, and the tutor's notes matching what was charged. When any of those lives in a different tool from the invoice, the invoice is wrong often enough that parents start checking it — and a parent checking invoices is a parent comparing centres. This cluster is about making the invoice right first time and the money arrive before the work, not after.
Pay per session is the simplest to explain and the worst of the three. Money arrives after the work, every cancellation is a refund conversation, every no-show is a debt to collect, and the centre is permanently chasing. It suits trial sessions and nothing else.
Packages and blocks — ten sessions paid in advance at a lower rate than one, with an expiry — put the money in front of the work. A late cancellation is a session deducted under the policy the family agreed to when they bought the package; a no-show is the same; and the renewal, when the package runs out, is a natural moment to talk about progress and the next block. This is the default for one-to-one and the first article works the arithmetic.
A monthly or termly programme fee — one price for a place on a group programme — gives smooth revenue and clean invoices, and suits exam preparation and ongoing courses. Its risk is the opposite of pay-per-session: the cancellation is one click, so retention is the whole job, and a family that drifts stops paying quietly rather than loudly.
Most centres that scale run packages for one-to-one and programme fees for groups, and use pay-per-session for nothing except the first trial. The mistake is not choosing the wrong model; it is running all three at once without deciding, so that every family is on a different arrangement and the office holds the differences in its head.
A parent who was not in the room judges the centre on what they can see, and the invoice is the thing they see most often. It has to show, session by session, what happened: the date, the tutor, the subject, whether it was attended, cancelled inside the notice period, cancelled outside it or missed, and what that meant for the package. An invoice that says "8 sessions — €320" invites a phone call; one that lists the eight sessions with their status does not, because the parent can reconcile it against their own memory in thirty seconds.
That level of detail is only possible if the session record carries the status at the time — which is why the scheduling cluster made it a requirement — and if the invoice is produced from the record rather than typed from memory at month end. The second article sets out what the invoice has to show, what it must not show (the tutor's pay rate, the internal notes), and the session-note habit that makes it right without an evening of reconciliation.
Centres that invoice by email and wait have a receivables problem they call cash flow. It is not cash flow; it is unpaid work, and it compounds, because a family that has attended for six weeks without paying has learned that the centre does not collect and every subsequent invoice to that family is a negotiation. Collection is a system with four parts, none of them harsh: a card taken at enrolment, so that a package can be charged rather than requested; automatic retries when a payment fails, because most failed cards are expired ones; an arrears rule applied in week one, politely, every time; and renewals offered before the package runs out rather than after, so that the next block is bought while the family is still attending.
The third article covers each of these with the wording that works, and the exception process for the family that genuinely cannot pay this month, which every centre will meet and should handle as a decision rather than a drift.
Several tutoring platforms charge a percentage of your revenue on top of a subscription, and some charge it even on payments they do not process. At a small centre it looks like a rounding error. At a few hundred sessions a month it is the largest number on the invoice, and it grows with the business forever, which is the property of every revenue-linked fee: cheapest when you are small, most expensive when you are successful. Ask for the percentage in writing from any platform you evaluate, and multiply it by the revenue you expect in year three, not this term.
On SprintUp, families pay your centre directly through Stripe and SprintUp takes 0% of that payment on every plan, including the free one; standard Stripe processing fees apply. Packages, programmes and one-off sessions are sold as products you define at your own prices, and each family sees what they have and what is due in the portal. We have compared this against the platforms that charge percentages, with their published figures, on the TutorCruncher and Teachworks comparison pages, including the sizes at which each is the cheaper choice.
Billing is getting the right amount from the right family for the right sessions, on time. Accounting is tax, payroll, VAT where it applies, year-end and the books. A tutoring centre with more than a couple of tutors needs both, and they are different systems: SprintUp is the first and is not the second. Keep the platform for sessions, packages and payments; keep an accounting package for the books; and let the platform's payment records feed the accounts rather than trying to make either do the other's job.
Choose the model, get the invoice right, and collect on time. Each ends with a checklist and template wording you can use at the desk.
