Discounting is slippery slope to be on...
These figures are from the book written by legendary entrepreneur and Financial Times columnist Mike Southon:
"1. Cut prices by 10% and you will have to sell 50% more to get to your break even point
2. Raise prices by 10% and you will have to sell 25% fewer to get to your break even point"
Instead of discounting, why don't you think about a way of improving your service so that customers will pay more?
Here are some things that have worked for us.
1. Get a 40ft pole with a goosneck and offer regular or at least annual cleans of the roofline windows.
2. Offer a premium service. as an add on. We charge £2 upwards for doing the ground floor fascias every time.
3. Offer to do the garage door.
4. Include the front door, but charge more for doing it.
Use features and benefits to sell your service.
A feature of your service is that you use soap free technology, so there is no sticky soap residue left on the glass.
The benefit to your customer is that the finish will last 4-10 weeks, depending on aspect; so the windows can be cleaned less often, giving the customer significant annual savings on their window cleaning bill.
A feature of your service is that while SOME window cleaners ONLY do the glass, YOU can include the glass AND the sills AND the frames.
The benefit of your service is that the customer will have a beautiful crystal clear glass AND frames AND sills, (and not just the glass only being cleaned).
Because you are cleaning the sills AND frames, with a reliable service every x weeks, they will always have a home that looks fantastic and this regular cleaning will also prevent their lovely valuable white windows turning grey over time.
