Please help - Contractor and Accountants Letter

Hi guys,

So I am planning to show self employed earnings as a researcher made (physically) outside the uk over a four moth period from October to January.

I've poured over the guidance and in particular what is has to say about Contractors i.e. those who don't operate a through a company and are not employees. This is me.

My problem is I didn't get paid for October and November until January (well outside to 30 day payment period). How should I account for this in terms of the gross and net pay over the 4 months? Show zero net and gross Oct, Nov and Dec and then lump it all together in Jan? (please note that as I am not versed in accounts, I want to be knowledgable with my accountant who will write the letter i.e. not just accept anything he tells me. I just want to know what has worked in your experiences)

I can get my client to write a letter explaining the delay in payment if you think that will help?

Otherwise I plan to show

1. invoices and late payment reminder letters I wrote to client;
2. personal bank account higlighting payments; and
3. payment vouchers (copies as the client keeps the original)

You think I will need anything else?

Thanks in advance for your help!

Anyone...Pretty Please?
