I used to offer full service cc work including most stain removals. red coolaid, a complete selection of differant "flavored deo's" vanilla, cherry etc.. Especially on moveouts, realtor work.etc..
Now nobody wants to pony up the dough for standard cleaning let alone pay for mid-grade services, cleaning plus basic stains.
Every now and again I come across somebody who wants to pay less than $200 for a 2300 s.f. filled with stains. I cleary state that the stains will need special cleaning as is the same with pet urine, with most cases.
I am probably the only non B&S company who has been getting residential..

I can not stay in business donating all the super damned expensive spotters and stain removers for free. Do you donate your hard earned cash too? 
and why are our consumables so expensive?? just basic parasitic inflation?? They do realize they can not survive with out US??

On res. nope. On commercial where I know I can get my money back no problem.

How I do it is for standard stain removal-no charge. Standard stain removal is defined as stains removed with normal cleaning procedure. Advanced stain removal is additional priced per occurance or stain - advanced stains removal is defined as requiring additional stain removing procedures and specialized products. I know others that charge if their knee touches the carpet for stain removal. During a phone call I ask questions age of carpet, carpet type, last cleaned, any substantial stained areas of concern. When I phone estimate I'm careful to include the estimated cost would be $$$ based on the information you have provided me with final exact price will be determined upon inpection when I come out to provide service. Many customers have never had carpet cleaned and assume everything is easily removed.

Most spot removal is included I'll even do 1 maybe 2 red stains depending on the customer. I charge extra for proper pet stain and odor treatment and if there is a lot of paint and or gum.

I just wanted to add more info. I have discovered a few years ago. I have been able to remove almost every stain imaginable including vomit, urine, fecal stains, baby formula, dog odors, some cat urine odors depending on the diet, paint, bearing grease, motor oil, tranny fluids on rare occasions, but Excluding red, wax, melted crayons, turtle poo..
Simply by applying a presray comprised of Liquid slurry punched up with citra-pure.. Then final rinse is with my Zero Residue, fast drying, self neutralizing, self deoderizing, self drying NuCleanse product.
So my mostest expensive consumable is the Citra-Pure @ $68 a gallon. and slurry at $45ish. Red-Relief $35 for a 12 oz.

The main issues I have is generally people think I do complete restorative cleaning for free and is included in any cleaning...

Case and Point: just got a call. asking if I do the $45 for any 5 rooms. Pet urine, dog odors, nail polish, purple Koolaid.. expected to be included. Heck fuel alone would be $30 just to show up 45 miles away!!.

I work like Jeff.  I'll give a quote but will charge more if warranted when I arrive.  I tell customers that this quote is for light to moderately soiled carpet and that heavily soiled carpet, urine, vomit, poop will be slightly higher.  Yesterday I arrived at a job and rugs were heavily soiled plus lots of cat puke spots.  Told custy, before starting, that this  is going to be a bit higher and re-quoted, than cleaned.  I used to just honor quote but got sick of that in a hurry.  I've  found that most people are reasonable and know that their carpet is filthy and disgusting and will cost more to clean.  The key is to tell them before starting other wise they're going to feel like your trying to rip them off if you ask for more after job is done.  I'd walk before cleaning at a price I wasn't happy with.

$45 For 5 rooms? Is that really what you advertise? If so, of course people are going to look for you in trashed houses. Just up your price, then cleaning up everything for one price will start to make since.  People love all inclusive, and its a way to think long term instead of short term. I would be pissed if a mechanic advertised 19.99 for an oil change then told me if I wanted a new oil filter with the oil change it would be another $10.

Heck No!!!!! They read an ad for a bait and switch company prior to calling me.. And just assumed it was the norm..
Yes I did take the job.. My basic cleaning naturally neutrilizes pet urine and odors..vomit etc.. Just some of the oddball stains do not come up. turtle poo, coke, pepsi.
I quoted $130ish. used the specialty chems on a lot of coffee. coke/pepsi stains and man that stuff sucked.. I cleaned cold water than spotted it and it did go away. Until I cam back to clean the room and it showed up more. And set the stains. So I have a job in the next town on Monday So I am going to use my world famous Borax to remove the coffee and coke stains..As always works upon contact. and is about 99.9999% cheaper than the crap I used..
