Automated Invoicing


Currently, when one completes our conference registration form, we manually prepare and email his/her invoice. We use Google Forms for this purpose. Does anyone know of a way that we could streamline this process by having an invoice automatically prepared and emailed to the submitter? Is there on online service that is recommended for this purpose? Thanks.


What platform or language(s) are you using? Do you have skills in a server-based language like PHP? If so, it should be straightfoward to use it to generate an invoice. You can either display an invoice as a (printer-friendly) web page, and have the customer print it in their browser. Or you can generate is as a PDF, store the file on your server, and display a link to let them download it.

If you need any more details, please let us know where you are starting from, that is, what system do you already have in place, what skills are available to you, etc.



Hi Mike. Thank you for your reply. This sounds quite interesting. My site was built in PHP with English platform. My general web designing skills are minimal at best as I did not design my own site. My site is Currently, I simply have folks complete an online registration form using Google Forms. Once I receive the submitted form, I use a free invoice service to manually prepare and email the invoices to the submitter. This process has been very time consuming and that is why I would like to mainstream it if I could.

I use Paypal for my online payments. However, the majority of conference attendees pay with personal/business checks. So, the invoice would need to reflect all types of payments. Additionally, I would need to manually edit the invoices should the submitter select to add or subtract attendees from the list.

If you could give me more details, I am definitely interested!



You say the site was built in PHP, but that you don't have any development skills yourself and you had someone else create the site. That's fine. What it means is that you need to get that person to add the invoicing feature. It's not something that I, or anyone else here, can explain to you how to do. I know how to add an invoicing feature to my own site, but I can't apply that knowledge to your site, because I have no way of knowing the internal details of how the site is coded.

As an alternative, maybe you should be looking for a way to streamline your existing manual invoicing procedure. You say you are using a free invoicing service, but that the procedure is time-consuming. Perhaps you need a different way of doing it. If your existing PHP developer can't add the feature to your web site, maybe you can find someone to create a free-standing application to handle your invoicing. (For example, in my own business, I have a simple home-brewed invoicing system that I set up with a bunch of Excel macros.)



Experiencing the similar situation, I just got switched to Handdy Invoices. Now, i'm able to send invoices to my clients online in a professional way. This is because, with most of the invoicing software we are intended to design our invoices. I can even prepare my invoices earlier and can get scheduled to the date on which it has to be sent.

I feel pretty convenient with Handdy Invoices. I think you can have a better try with this, if you're concerned to opt for a free invoicing software.

I have to make an invoice system for my coursework, but I can't figure out how to make an invoice number which changes (+1) every time I open the system.
Please help if you can!

Thank you for your recommendation. However, I was looking for an invoice software that could automatically create invoices after one completes the conference registration form. Right now, we manually create the invoice. It would be quicker and easier if we could find a software that does this for us.
