how can I accept ACH payments or wire transfers

[Estrong]

I have several customers who would like to use ACH

there is no direct way with Paypal,they can do ACH from bank to their Paypal account and then from their paypal account tp your paypal account.

or do it outside Paypal,they will need your bank routing number and account number.

Some sellers are leary giving away their bank routing and account number.

There are som printers which can print some fancy business checks,money orders and even USPS postal order (with no watermark)
