Hello!
I'm WHMCS admin user/developer already since v2.2 (somewhere in year 2006), did many template customization, hacks & hooks, provisioning modules and payment gateways (last was The Ethereum & Bitcoin payment gateway for WHMCS 7.5.2 and yesterday i developed InterKassa gateway for WHMCS 7.6.1).
I feel this project was made for me, as i previously designed (supervised by accountant) & developed similar integration, to automate accounting & book-keeping of WHMCS using Kashflow.
Taking into consideration EU/UK regulations, exchange rates, VATMOSS (if product is digital good) etc.
- This module works happily with Katamaze billing module - and completes it.
I am also well familiar with accounting / VAT & VATMOSS regulations in the EU.
Please PM me to discuss and brain-storm on ways i can automate and release you from the dirty job so you can enjoy the charts!
Note, my offer is not final. Once we clear up the requirements i will provide exact time & costs estimate.
Looking forward to work with you,
Mathew
p.s: Sorry for the long intro :)
