I keep a timesheet that I share with you at the end of each session. You confirm the hours we worked, sign off on them and then you pay me. If our work together includes my time off-site which is often sourcing, creating floor-plans, detailed instructions for your DIY, or errands, we discuss it beforehand, I only proceed with your knowledge and approval and we add it to the timesheet. On occasion, as I’ve described above, I make other arrangements but in all cases, hours billed are transparent.
