Most issues have a simple cause. Try these first.
"It says insufficient stock"
You are trying to sell or remove more than you have. Record a Stock In first, or check the real quantity.
"I can't see a page or button"
Your role may not allow it. Ask the business owner to check your permissions under Staff / Members.
"My profit looks wrong"
Make sure every product has a cost price and selling price, and that staff expenses/sales have been approved.
"A change disappeared"
If you are a staff member, the change may be waiting under Approvals for a manager to approve.
"The page looks squeezed on my phone"
Rotate to portrait and refresh. Tables scroll sideways with your finger.
