Get First Day and Last Day of previous month in SQL Server

I want to get previous month report.

For e.g., if system date is March '2023-03-04' and i need previous month report with first date and last date

select *  from purchaseinvoice p where convert(Date,p_date)  between '2023-02-01' and '2023-02-28'

if system date is July '2023-07-08'

select *  from purchaseinvoice p where convert(Date,p_date)  between '2023-06-01' and '2023-06-30'

I need a general mssql statement. Please provide answer.
