Talk:ADempiere Dunning

This Wiki is read-only for reference purposes to avoid broken links.

From my point of view, and I think from many other end users as well, I think the charge and interest functionality is of most importance to complete.

I run Adempiere for my own company, and it's a big hassle having to add fees and interest manually. It's hardly worth the effort. Fees and interest are the main "pushing" methods of getting a late paying client to pay. If there are no fees or penalty interest, why should they pay me first if they are short of cash.

Great job documenting this :-)

Thanks Daniel, agree with you it's one of the most common cases, and unfortunately is not covered by default in Adempiere. We could start at least collecting the different needs of this kind of interest calculation, how is this process on most countries. For example

• in Colombia we have two cases, some companies charge interests based on the number of days since last dunning, others charge interests monthly
• By law there is a maximum interest rate that can be charged, it will be great to control that user don't configure a level over this maximum
• There are companies that invoice interests and fees, this business case sounds easy to support - sounds like executing a post-dunning process to create invoices based on interests and fees
• There are companies that just inform interests and fees but don't invoice, this is because this money is expected to be hard to collect, and invoicing immediately will raise the incomes of the company with corresponding tax payments. In this case the interest and fees must be invoiced (or allowed to be typed) on payment
• In Colombia there is an additional problem - interests must charge the same taxes of the original sale - so the interest can be different for each line of the invoice. This sounds really hard to achieve with the current dunning model, we would need a different table correlating interest charge with invoiced products/charges, and have different interest charges with different taxes

 :-) I guess this is why interest calculation is not done in Adempiere by default. The rules can be country-based, so in these cases, Adempiere must allow a configurable module, and ability to call localized classes or rules. / CarlosRuiz_globalqss 08:42, 28 November 2009 (PST)
