We sell custom stickers and have had our own website for a long time. We connected an online cash register from a well-known bank, launched advertising on the site, sales started, but many customers did not complete their payments. We began to investigate and found out that we had a high abandonment rate, but technical support couldn't figure out the reason. We switched to YuKassa and have been using it for 3 weeks now – no problems have arisen since.
