WP-Translations Follow-Ups is the best way to keep your translations up to date.
Principle is easy: each month we send you an invoice with a Follow Up fee based on your number of locales and the exact new numbers of words we translated during that month.
What happens if you make many strings changes? Just let us know you’re in dev mode and we’ll wait until you change back to a production mode: we’ll start our full process only from there, and you will pay only for those new strings.
And don’t forget to check our TranslationsPress Language Pack features to provide in real time updates to all your users directly in their WordPress Dashboards.
