Hello, our agricult coop had price changes in May. Now I find invoices for August with those changes not being respected; all of them still do have the old price. Is that intended behavior? - IMHO, when price of a product is changed, next invoices to be created should have the new price. EG ---

It does if the price on the subscription line is modified. ---

We had a similiar discussion some time ago: [Update price of multiple subscriptions](https://discuss.tryton.org/t/update-price-of-multiple-subscriptions/1710) but there is no implementation for it. ---

> [@ced](#): > > It does if the price on the subscription line is modified. So you’re telling me that I need to update the price of every manually? - AFAIK, the consumption and invoice wizard creates consumptions and invoices back in time till the given date? - So, do I have to end subscription lines before price change, and create new ones from that date on ? That would not be so charming… ): EG ---

You have to invoice all the consumption at the older time before updating to the new price for the future consumption. ---

I don’t know what other people expect; I’d expect that invoices are created on base of the amount for the invoicing period. I can think of several solutions: 1. “create-invoice”-wizard does not take the price from the subscription line, but from the product 2. “create-invoice”-wizard checks, if product price and subscription line prices are different - in case, it ends subscription line at the recent end of billing period, and creates a new one for the beginning of the present billing period EG ---

Shall prices be changed? - ‘Yes’ - ‘no’ - ‘cycle through all cases affected and let user decide for each case’._ ( not sure if the latter ever is required). EG ---
