try the link above. It may or may not help. Good luck.

Open scanned document, right click on document, click on save as, type in invoice # and last name.

You need to contact the software developer. It appears it has a glitch. I'd recommend quickbooks for your next invoicing software

You might also try a free Invoicing software that can manage your business, time tracking and manage your expenses.

I am not sure how you are trying to open them but the way I mite try is put the backup file cd ? portabl hdd then open avenquest

1. If you paid by credit card or bank deposit, send a copy of your bank statement, which will show the payment.
2. If you paid by PayPal, the payment should appear in payment history on your account.
3. If you paid by Western Union, only the seller can mark it as paid and you don't have any power over it.

Open the apply payments window and choose the customers name at the top. Click next to the invoice that you want to pay and then at the bottom of the screen look for the button that says discounts and credits. Click on it and then choose credits. The credit should be listed there to apply to the invoice. If you have tried these steps

Is it in a single-user environment? You can save the current invoice number to a text file then ope that and +1 (which is the way that the demonstartion Invoice in Excel 97 / 2000 used to do it ).

After emailing Nova Deveolment I played with the Invoices & estimates software. I was able to open a new invoice by: Clicking on the "paid" invoices folder and then clicking "New".

if you are using office it can be set to not send some attachments.
it is usually safe to rename the extensions on them to something stupid.
make a copy of the file first .
but to rename the extension you have to see it first.
open any folder and goto the tools/folder options/ uncheck the hide extensions for known file types.
hit ok
then you can see the extension of all file names.
See if that works for you.
Other times its the size of the file you are sending
the normal limit is 2 meg for email.
