How do I get paid faster on completed jobs?

Cash flow problems usually are not about how much you charge. They are about how long it takes to collect. Every day between finishing a job and getting paid is a day your money is working for the customer instead of you.

Every day an invoice sits unpaid, it is less likely to get paid.

Send the invoice the moment the job is done, not that night or next week. Make it payable online in one tap, and let automatic reminders chase anything unpaid so you do not have to. See invoicing and payments.

On bigger jobs, collect a deposit up front and bill progress payments as you go, so your cash flow never depends on one final check. See job project management.
