A quote is a document with a clock on it. Most people read the rate and skip the line that says how long that rate stands. Do not skip it.

If you compare two agencies on the rate alone, you may be comparing two offers that expire on different days. One may hold its price for a short window. Another may hold it for a long one. The page looks the same. The offer is not.
Find the validity line
Look for a sentence that says how long the quote is valid and counts from a stated date. If you find it, write the date in your notes. If you find no line at all, write 'no validity stated' next to that agency's name. That is a finding. It tells you the rate is a starting point, not a commitment.
Check the start date it assumes
Many quotes assume a start date. Ask what the rate becomes if your start slips by a week or by a month. Ask whether the agency will re-issue the quote on the day you actually begin. If the answer is no, you are buying a snapshot.
Ask how rate changes are noticed
Ask how much written notice you get before the agency raises the rate. Ask whether that notice arrives by letter, by email, or as a line on the next invoice. Then ask what you can do if you do not accept the new rate. Get the answer in writing. If the agency cannot say it plainly, the quote is not ready to compare.
What it costs: The Missouri median for non-medical in-home care is $33 an hour, per the CareScout (Genworth) Cost of Care Survey 2025 state data tables, released March 2026. New Plan Care's standard rate is $34 an hour with a four-hour minimum, so a visit starts at $136 (newplancare.com/services).
Put two quotes on one clock
Lay the two quotes side by side. Write each validity date on the same line. If one expires sooner, ask that agency to re-issue its quote with a window that ends after your decision date, or ask the other agency to do the same. You want both offers standing on the same day.
Get the clock in writing
Do not rely on a phone call to tell you the validity window. Ask the agency to send the quote and its expiry line by email. Save that email with the quote. When you call back, read the date out loud and ask them to confirm it. A verbal promise is not on the page.
What to do with the result
Set your own decision date first. Then shape your comparison to fit inside the quotes' windows. Do not let a sales call set the deadline. The quote sets it, and only if it is written down.
