Hi,
What stopping you from having Additional Box of Account Ref. under Account Summary or any where on statement.
Most of our clients pay for so many invoices together by bank transfer and payment reference they can put as Account Ref. And believe me it is very easy to know by them Account Ref. if available on statement.
On each statement we enter:
No payment by cash or cheque will be accepted
Our bank Details
BANK NAME: xxxxxxxx
BANK SORT CODE: xxxxxxxxx
BANK ACCOUNT NUMBER: xxxxxxxxxx
BANK ACCOUNT NAME: xxxxxxxxxxxxxxxxxxxx
PAYMENT REFERENCE: USE OUR ACCOUNT REF.
Actual dedails replaced here by xxxxxxx.
Regards
