Charging at the end and hoping they pay? Get paid up front.
Prepaid bonos and packages: get paid up front and build loyalty; each session is deducted automatically when the appointment is validated. Know who pays, with a client credit score and debt control, and the till reconciles itself at close.

Do any of these sound familiar?
If you manage a center, you probably deal with at least one of these every day.
At close, what you billed never matches what you collected
Balancing the drawer at the end of the day takes too long and never adds up on the first try. Every euro off is time wasted hunting an error no one can explain.
Packages get deducted wrong, forgotten or given away by mistake
Your staff doesn't know how many sessions remain, clients dispute, and sessions already used get handed out again. Every mismanaged package is money you collected up front, leaking session by session.
You don't know which service is profitable and which costs you money
Revenue per service, per family and per professional... you have no real visibility. You raise prices blindly or keep treatments that lose money without knowing it.
You defer payments, nobody follows up, and they turn into bad debt
Deferred payments get lost in the daily routine. With no follow-up and no risk control, the debt grows and you absorb it as a loss.
What you don't control is costing you money
This is what we see every day in centers still running the drawer and packages by hand.
small cash and discount errors that go undetected until month-end
lost balancing the drawer by hand and reviewing pending payments one by one
from packages already paid for, served twice because no one tracks the balance
Every euro off comes out of your own pocket. And without clear financial data, every decision about pricing, services and staffing is based on intuition, not facts.
A case you will probably recognize
A beauty center with 4 rooms sells 10-session packages on paper. Reception jots down the deductions by hand in a notebook and the drawer is balanced from memory at close.
The result: every month sessions get served twice, drawer gaps no one can explain, and expired packages that keep being accepted. Money already collected leaks away, service by service, unseen until month-end.
With Qleven, every session deducts itself when the appointment is validated, reception sees the balance on screen, and at close the system flags the exact gap per payment method. The notebook disappears and the money stops leaking.
From ticket to accounting entry. Automatic.
Unlike a lightweight booking-and-checkout tool, Qleven is a real financial suite: error-free packages, drawer reconciliation, VAT and double-entry accounting. All integrated with your schedule.
Automatic billing
Invoices, proformas and credit notes generated from every validated appointment. VAT calculated per line. No manual entry. No oversights.
Packages, bundles & gift cards
You collect the package up front and every session deducts itself when the appointment is validated. Your front desk sees the remaining balance on screen at any time. No sessions given away twice.
Cash close with real reconciliation
Open, close and count by payment method (cash, card, transfer, check). Qleven computes the exact drawer gap in seconds.
Deferred & installment payments
Split payments, installment plans and deposit management. Flexible for clients, recorded and controlled for you.
Profitability per service
Revenue per service, per family and per professional. Know exactly what works and what costs you money.
Debt control & credit score
Debt ledger, per-clinic policies and a per-client credit score (green / yellow / red) with auditable history. Risk under control.
Two advantages that protect your register
Per-client credit score
Before deferring a payment, Qleven shows a green / yellow / red score per client, with a debt ledger and auditable history. You know who you can extend credit to and who you can't, before you collect.
Gift cards & store credit
Issue and redeem gift cards and store credit with full traceability. An up-front revenue lever most booking-and-checkout tools don't even offer.

Frequently asked questions
Everything you need to know about billing, packages and accounting.
Can I configure VAT for my country?
Yes. You define your VAT rates with VAT-inclusive or VAT-exclusive pricing, and VAT is locked on every document line. Numbering series are managed per legal entity and fiscal year.
How does package and bundle control work?
The client pays for the package up front and, every time a linked appointment is validated, the system deducts the session automatically. Your front desk sees remaining sessions on screen, with validity and expiry dates, to tell the client instantly.
What payment methods does it support?
Cash, card, bank transfer, check, deferred payments and mixed combinations. You record each payment and assign it to the matching cash session.
Does it include accounting?
Yes. Qleven runs double-entry accounting: a configurable chart of accounts, automatic account mapping and automatic journal entries from tickets, invoices, payments and cash closes, with reports such as journal, general ledger, trial balance and income statement.
Does it integrate with the schedule?
Yes, billing is fully integrated with Qleven's schedule. When an appointment is validated, the ticket and invoice are generated with the correct service, professional and price, and the package deducts itself.
How do I control unpaid balances?
With a debt ledger, per-clinic deferral policies (strict, balanced, flexible) and a per-client credit score with green, yellow and red bands plus auditable history. You know who you can defer and who you can't before you collect.
