Invoicing Software for Car Rental & Leasing Companies in Singapore

A weekend self-drive, a 24-month corporate lease, a replacement car for an insurer and a chauffeured airport transfer all price differently — daily rate, mileage cap, excess-kilometre charge, CDW waiver, delivery fee. Building each invoice by hand in a spreadsheet is slow and it is where mistakes creep in, especially when a customer extends by two days at the last minute.

You hold a security deposit at pick-up, then deduct for a kerbed rim, a missing ERP top-up or a late return — and weeks later nobody can reconstruct what was withheld and why. Deposits sitting in a shoebox of card slips are not a liability on any ledger, so your cash position and your customer disputes both get messy.

One car is out on hire, one is in the workshop for servicing, one is due for its inspection and road tax renewal, and one has been promised to a walk-in who hasn't paid yet. Without a live view, you either double-book a vehicle or leave it sitting idle in the lot — and an idle car still costs you finance instalments and insurance.

Rental income, recharges, workshop bills, insurance, financing and fuel all have to be captured, categorised and reconciled before you can file a GST F5 return with IRAS. Re-typing counter takings into accounting software at month end is dull, slow and easy to get wrong — and corporate clients are increasingly asking about InvoiceNow (Peppol) delivery.

Set up rate cards once — daily, weekly, monthly lease, mileage bands, CDW, delivery and collection, late-return charge — then build an invoice by picking the vehicle and the dates. Extensions and add-ons are added to the same job, GST is applied line by line at the correct treatment, and the invoice goes out by email with your GST registration number on it.

Take a deposit at pick-up and Tallium AI records it as money held, not as revenue. At return, release it, deduct part of it against a damage or fuel charge, or roll it into the next hire — the invoice, the refund and the ledger entry all stay linked, so when a customer queries a S$300 deduction six weeks later you can show exactly what happened.

Every vehicle is an item with its own status: on hire, available, in the workshop, off-road for inspection. Book a car and it's held; return it and it's free again. You can see at a glance which units are earning and which are sitting, and set reminders for road tax, insurance renewal and servicing so a car never quietly goes unhireable.

Counter payments, invoices, deposits and expenses post to the ledger as they happen. Photograph a workshop invoice or a fuel receipt and AI receipt scanning reads it and files it against the right vehicle, so you can see the true margin per car. Come filing time your GST figures are already assembled — always confirm current rules with IRAS or a local tax professional before you file.
