Title -- specifically, if i have access to a client's ignition gateway but not their initial purchase agreement and want to buy them webdev (I have consent from the client for this), what's the purchase process for that?
Contact your sales rep (and have the license handy) and they will be able to provide a quote.
Also remember to check with the customer if they want to use you for their licensing moving forward, with their permission, IA will send the support package renewal reminders through to you, which is a really easy way to keep in touch with them and you can keep them supported just that little bit easier.
We see a fair few places now that had an integrator do some initial work, but since then they have had no contact from anyone. Ignition is a continuous improvement platform, so there are always ways you can value add someone’s existing platform.
