I believe you've laid out a robust framework that addresses several key aspects of our current challenge. Your emphasis on flexibility within the payment and invoicing structure is particularly insightful.
Firstly, the idea of a separate table for 'money' alongside a linking table 'invoice2money' is a significant improvement. This structure not only simplifies the recording of diverse financial transactions but also enhances our ability to track and apply payments accurately. It's a more granular approach that gives us the needed flexibility for various scenarios, including partial payments, overpayments, and refunds.
Regarding your point on the 'amount_paid' field in the invoices table, I agree that it adds a layer of convenience. However, we might want to avoid this for the unneeded db writes.
Your approach to payment entry, particularly the differentiation between payments linked to specific invoices and those without, is crucial for compliance and financial clarity. In Europe, as you've pointed out, the clarity in payment allocation is not just a best practice but a compliance necessity. This distinction also helps in cases of disputed invoices, allowing us to maintain transparent and accurate financial records.
The idea of including a field for 'Comment/Text' in the payment form is also a thoughtful addition. It can provide context for the payment, which can be invaluable during audits or when reconciling accounts.
Lastly, I strongly support your suggestion regarding overpayments. Automatically adjusting the 'To Pay' amount of future invoices when an overpayment is detected streamlines the process and enhances customer experience by acknowledging their previous overpayments.
Overall, your proposed structure seems not only to address our current operational challenges but also positions us well for scalability and compliance. I'm excited about the potential of implementing this.
