@NotaryLadyBre : You have to have a bookkeeping system in place - something you can control. I initially used QuickBooks. However, years ago, my computer crashed and I lost everything in it including my QuickBooks. I ended up having to recreate and went with an online free program from WaveApps (they also have a paid subscription plan). Their basic plan is all I need. The program allows me to generate an invoice for every assignment, produce most reports I may need for comparison, accounting and tax purposes.
You’re a business now. It’s time to act like one and accept the responsibility of keeping your records (or hire someone who will do it for you).
Congratulations on having and keeping a busy business!
