Dave,
your points are very valid ! they can actually be addressed with a bit of programming ! I guess this is the "cost" of going down the opensource route versus paying for a sometimes more complete software.
- re: pdf generation - you might want to look at this thread:
viewtopic.php?f=23&t=5996&p=23915&hilit=dompdf#p23915- re: notifying the customer... it is fairly simple to add this to the batch billing script - if you have someone at hand that knows php, I can email the 5 lines that do this trick - though if you succeed in applying the PDF patch I've just indicated, you probably can do this yourself !
- re: notifying customer and emailing the file.... hhhmmm... still have that one on my todo list (not sure if I'll do it, though !)
- detailed CDR along with the invoice... I would not do this - What I've done is send a recap of calls per tarifplan (which in my case match the tariff zones). Then, downloading from the customer UI triggers the question of performance, and this community seems to have voted against !
- tax calculation in the US is an absolute nightmare - back in the 90's, I remember that taxes were calculated based on the city, state of origin & termination of the call.... you had to connect to specific packages to do that. Unfortunately, tax calculation is a bit weak with A2B - this one is going to be hard to overcome in your case !
Next, you'll see that payment management can also be improved - namely, a payment can only be assigned to one invoice !
but finally, I've worked with a couple of multi-million $$$ billing packages, and A2B is very close from them in terms of functionality, and quality !!!
dont hesitate to revert if you need more help
