All Be My Guest Wedding Invitations come with two rounds of revisions free of charge (see section 3 of the Terms and Conditions for more info).
That’s more than enough for most clients, but occasionally you might need more (perhaps you had a change of heart on your wording choices halfway through the process, for example). A revision round is considered to be every time the designers send through a revised PDF, so group all your changes and feedback together, to avoid this altogether. Each additional round of revisions that you require is an extra $25.
We recommend you wait and see whether you need this add-on – don’t buy it “just in case” at the same time as you order your invitations – as most people do not end up requiring the extra revisions.
