Yes. The number of quotation requests that you are able to answer are limited on abarlink website based on membership plan (More Information).
For example; if you are a FREE member (A member of the “Starter Plan”), you are only allowed to answer to the first 100 requests and if you receive more requests, you will not be able to respond to them. If you want to respond to more requests, you need to purchase the “Package for increasing the number of incoming transaction requests or pre-invoices”. (More Information)
