When starting out as window cleaning and other cash work as main job it will be tough financially. What is the best way to go in the beginning? I heard that legally you should always give out invoices ( where would you buy these?) WH Smiths? And if you didn't give out any to customers would that be as dodgy as hell? What do you do with the cash you have received from each individual customer? Just put it into the spreadsheet or record it in a book? To give you a bit of help in the beginning. Can you sign onto Universal Credit and register as self employed at the same time? I imagined that if you worked more than 3 hours a week, wouldn't tax credits be better than universal credit or are they the same thing? Are there people who just work and don't declare anything on universal credit or jobseekers? ( of course there are), but is it better to declare 2 or 3 hrs until things get going? (in case someone who works in the job centre spots you.) If I think I will need to sign on from next Monday should I do it now and put next Saturday as the start date? Should I go into the job centre and say- I am on zero hours (on zero hours contract in PAYE job which will probably lose soon. Being on zero hours entitles me to sign on without being fired. I can say I may get some PAYE work but maybe not and I am trying to start my business but think I may only have 2 hours a week in the beginning? If I say I might be working is it going to be a nightmare?
