Frequently asked questions
What is the difference between a flat rate and an hourly rate?
A flat rate is one agreed price for the whole job, whatever it takes. An hourly rate multiplies a price by the time spent, so the final bill is unknown until the work is done. Flat rates give customers certainty; hourly rates protect the worker if the job runs long.
What is the difference between flat rate and fixed rate?
They overlap, but flat rate usually means a single price for a service regardless of quantity used, while fixed rate usually describes an interest rate on a loan or mortgage that will not change during an agreed period.
