I don't do many CIS Tax Returns so forgive me on this one.
Potential client (Electrician) sent me a spreadsheet just giving monthly figures of income and costs. I am normally more comfortable seeing a more detailed spreadsheet breakdown or CIS Subcontractor Statement / Receipts plus bank statements.
Costs seem inflated as he only made a profit of 5K on a turnover of 35K when for a service based profession should actually make much more profit. I have requested the bank statements. I doubt he will appoint me as his accountant for this reason which doesn't matter
Though it did make me think - do other accountants request more detailed information or do they accept the clients workings ?
