I work in a practice where we have a few various ways of invoicing our clients: be it time (old school I know), value billing, quarterly, annual, etc.
A client is changing accountants (no dramas) but we are finishing off their payroll up to the end of the tax year. I have told her what the expected fee will be in April 2020 (when we will have finished our supply of services). We won't be billing her until the we have done the work. This may be alien to some of you?
We post our time, produced WIP, then create the bill (either time or value) and write out the WIP at the same time.
I therefore cannot produce an Invoice for the client now as we have not done the work yet as our system does the bill and write outs the WIP at the same time.
We have only been acting for this client for 14 months, but did two years accounts. I am wondering how her old accountant invoiced her: as in before the work was done?
Can anybody give any insight to their procedures please?
