Retail sales by weight barcode in the cloud, perhaps?

Question

Electronic accounting

Good time.
I am looking for software that supports weight barcodes in the MySklad format.
He is good for everyone, of course, except for this nuance. I have a lot of weight goods. It is very inconvenient to drive in weight every time, and for a long time. Service time is critical. Tell me what is similar, with the functionality that I need.
