Every job quoted before I touch it. Parts at cost, no markup. If a fix costs more than the machine is worth, I'll tell you. By appointment in Docklands — no walk-ins.
Labour quoted before I start. Parts at cost — I'll show you the supplier invoice if you want to see it. If a repair isn't worth doing I'll tell you, even though it means I don't get the job. Bank transfer, PayID, or cash on pickup. GST invoices for business clients.
