Hi RussH There is no default restriction that prevents you from posting in previous years. You can select any date for a transaction as long as the date is later than your account start date. You can check your account start date under Settings > Financial Settings. 

Hi Michelle,
Thank you for the response.  Just to confirm, under Settings>Financial Settings - we would choose
ACCOUNTING DATES > ACCOUNTS START DATE  & enter May 1, 2020 to be able to enter invoices from that point on?  Our year end is April 30 2021 so that is entered in the appropriate box.
Thanks

Hi RussH Yes, you would enter May 1, 2020 to enter invoices and other transactions starting with that date. 

Thank you!
If you don't mind, there is another question...is there a way to set up the shipping costs to only add GST not have to select this tax option each time?

RussH The tax on shipping will always default to the main rate for your province. If your province has PST, it will default to GST + PST, and you will have to select GST each time. There is not a way to change this default. 

Thank you!

Hopefully, you don't mind another question...
I had asked it in another post, but no response as of yet.

In regards to "One time Customers" and not opening an account for each one.

Along with our repeat customers we have many one time retail customers.  On Sage 50 Desktop,  we set up one time customers as follows: Cash Customer.  Visa & MC Customer. etc.  The "Delivery Address' was the customer name and address.

We could at least locate their purchase invoices as needed through the 'Delivery" name or address. without creating an account for each customer.
Will this method work with Sage Business Online Accounting? Can we keep a record of and search the invoices in the same way?  If not any suggestion in how to handle the 'one time customers invoices'?

Thank you very much for your time & responses,

Hi RussH In order to keep track of invoices, you would have to create an account for each customer. There is no way to search invoices by Delivery Address in Sage Accounting at the moment. If you want to look up invoices later but not create new customers, you may want to use the reference field on the invoice. This field can be search on the invoice screen and reports. 

Thank you.  This is helpful &  good to know.
