Can I get a manual invoice? (or) Can I pay by AMEX?

We are able prepare you a manual invoice, which can be paid using AMEX (via PayPal), by cheque, or by money order.

The process is simple, and you can get started right away. There's no need to get in touch with us to organise anything in advance:

• Fill out this form
• We will email you an invoice (these are manually prepared, so it won't be instant)
• Using the instructions on the invoice, make the appropriate payment
• Let us know that you've paid (optional, but will speed things up)
• We will add Optimal Workshop account credit to the account with the email address you provided
