I would willingly swap my commercial work for domestic, yes commercial pays better but with domestic you can built a good working relationship with the customer and they are more likely to stay loyal to you.
you can also build a good relationship with commercial but as soon as someone cheaper comes along no matter what your out.
I have an £850 monthly commercial clean which is great but its a large private estate and when something is going on there I am not allowed to come and clean and this was made clear to me when I did the quote, well in April and may they had guests and film crews so I lost out on 2 months worth of cleans ( £1700 ) and as a small business thats very had to absorb, same thing in August ( £850 )
when you lose a domestic its not hard to replace and its easy to absorb
yes commercial is great when it goes well but domestic is bread and butter and I wiould much rather fill my order books up withh domestic, believe me the grass isn't always greener on the other side, especially when you can wait up to 3-4 months before you get paid of some jobs.
