Pre-payments in Abtrac help manage deposits required before starting a job. They are often outlined within a job quote. To set up a pre-payment, enter the amount in the "Job Billing Details" section and optionally configure job statuses or timesheet alerts. When invoicing deposit fees, businesses can charge a fixed amount, a percentage of the total fee, or cover specific application costs like council fees. By tracking pre-payment statuses in quotes or jobs, Abtrac ensures accurate financial records and prevents work from starting on unpaid jobs.
