How to replace party mail?

Question

API

Actually, subject.
The Russian Post (more precisely, its branch) requires switching to Party Post, bringing them a file from it along with the items, eliminating the need for manual data entry for each item.
What can replace this Win-program? Does anyone have experience of independent generation (as I understand it, you have to calculate delivery rates) and generally work with the Russian Post on volumes without resorting to this monstrous software?
In particular, the questions of the allowed weight error are not clear (which now you have to drive in yourself)
PS we know about the "sending" mail service, but it is still available only from Moscow

Answer 1

Desch, do you want to switch to EMC for example? Or other transporters (Boxberry, pickpoint, SDEK) The tariffs are now acceptable for many and the courier arrives to pick up everything.
Sorry if this is off topic. Watch what you sell

Answer 2

We simply upload a file that is sucked into the Partition mail.
It turned out to be much easier (faster, cheaper) to do than to completely replace Party mail.
And much cheaper and faster.
Partition mail is already a very multifunctional program to replace it.
The main thing is not to make it easier.
You pay for the weight.
If you pay a little more than the actual weight, the Post Office will not object.
