UPDATE:
Last week I've been going through the google spreadsheet which is the output from the google form. After filling out the form, many of you wanted to change stuff. I had to check all communication (PMs from Gh, Dt and Reddit as well as emails) and make sure everything is correct in the spreadsheet. I put together a script that was supposed to help me. Paypal can output a file for me with all emails of the paid SKB-invoices and the script just compared that against the emails in the form entries. Strangely the amount of unpaid invoices was still quite high according to the output of the script. When I went through the list of unpaid ones I quickly noticed some names that I know for sure had paid. What was wrong? Well some of you paid the invoice with a Paypal account that had a different email address than the one you put into the order form. That's why the script didn't find a match. So in the end I found myself going through the whole sheet manually. Man I can tell you this together with bringing the order sheet in line with all the changes discussed via PMs took me quite some time. Had to check again so many times cause whenever I did, I found another mistake.
Now the spreadsheet is error free (99% sure)!
Result:
When I started sending out invoices, 149 had entered the order form and as you know a lot (over 40) hadn't paid after the first month. Now after another month has passed and thanks to the reddit post, 144 have paid their invoice and this means I now have to decide on how many extras I will add and then I can ask for a quote for final production, then pay and by doing so kicking of the production.
Until then:
The order form will remain open so getting an SKB is still possible. Who fills out the form will get an invoice quickly. If I'm out of extras of a particular version, I'll just take it out of the form.
I didn't had time to bring the Reddit GB post over to mechmarket jet, like some of you told me I should do so. I'll do that today (99% sure).
