I only started last year & have just had my inspection so all my policies, new starter forms, parent packs etc are up to date & TBH unless something prompts me otherwise, I don't intend to look at them again until end of August when the annual review is due 
.
I do invoices on the 25th of each month in the evening & submit to parents by email there & then.
I make sure I do my accounts each month within the first week of the following month (ie just about to start march) - I use the NCMA books and staple receipts onto the back of the corresponding month - one day I'll set up an excel equivalent but for now it works ok.
I use my iphone to take photos for LJ & observations which I then send to Orbit & write a brief note if not immediately then later that day before I forget the moment!! I try & log on to the Orbit website a couple of times a month to write up a proper observations, link to EYFS, next steps etc and save to the child's LJ. Once a term I send home LJ with a termly 'update', space for parents comments etc.
Daily dairies for under 3's are written in the child's A5 notebook daily usually at tea time or just before they go home & I try to keep max 1 page per child.
Attendance register - I use 1 page print out per week for all children & only ask parents to sign if they are late collecting. TBH unless I want a parent to sign it, I rarely complete it & had to do 7 weeks worth before Ofsted came so maybe not to the best example 
Visitor Log - 1 page with instructions to visitors kept by the front door & up to date.
Once a term I do a 'newsletter' type email which is welcoming new starters, my holiday dates, term dates inc. inset days, request or thanks for doing questionnaires/feedback forms etc and keep a record of this & any responses in my 'working in partnership' file.
Fire evacuation proceedure - did it once, ridiculous, not doing it again unless I suddenly find myself looking after vast numbers of children I can't control! Utterly pointless exercise which did nothing to prepare me or mindees (age 8 mths & 10 mths ) for the real thing so I'm just going to fill in my log to say I've done it once a term but probably not get around to it until the weekend before my next Ofsted Inspection 
At the beginning of the year I did a yearly plan with month-by-month breakdown showing activities & links to EYFS (took bloody ages but most can be rehashed or reused for next year) - great if you have lots of pre-schoolers not so if it's only older ones for the odd hour after school or babies IMO. It can be helpful to prompt activity ideas, Ofsted loved it, some parents like it, good way to link into pre-schools etc but certainly not essential & quite a faff.
RA's - I did so bloody many when I started & rechecked prior to inspection & try to update if anything significant happens but I'll be honest & say I don't normally worry about RA - I think I'd lose the will to live if I started a formal daily RA or wrote one every time I set foot in a new place. I rely on common sense, mother/childminder instinct & watching over mindees
