I wanted to say the same.
One more thing, just wanted to keep you abreast of so that you don't need to be anxious about:
After submitting the invoice, it might take a couple of days or sometimes a little bit more than that for getting the money transferred. But as soon as it is done, you will be notified by an email from Techulator.
One more tip is, better you save the invoice in your system, afterwards, for every month you can simply change the date, invoice no. and amount before you upload it.
