WordRate is a quoting tool with client rate cards and glossary storage, so the honest question is whether your bottleneck is the quote or the rest of the business.
Most freelance translators reach for software at the same moment: a PDF lands at 4pm, the client wants a price before they leave for the day, and the last three quotes for that account are buried in sent mail. WordRate exists for that moment. It counts the words, applies the rate card you saved for that client, respects your minimum fee and rush tier, and gives you a number you can send in about ninety seconds. The glossary for that client is already attached to the same record.
The tools below are real products this trade evaluates, and each assumes a different shape of work. Some are built around the full freelance admin stack, from job record to invoice to year end reporting. Some are project management systems that assume a client side and a vendor side with money moving between them. One is an enterprise platform for agencies with dedicated project managers. None of them is wrong. The comparisons here are written as fit questions, because a two person shop in Tucson and a fifteen vendor agency in Chicago are not the same buyer.
