PreparedDocs for immigration
The law is the part you trained for. The rest is chasing a birth certificate for six weeks, finding out the passport scan is missing page two, and assembling four hundred pages into something an officer can follow. PreparedDocs does that part.
Built for immigration attorneys and accredited representatives.

The reality
Not the version in the process document. The version that turns up.
Taken over nine years, in no order, several of them the same picture at different sizes. Somebody has to caption them, date them and lay them out as exhibits.
The checklist lives in an email thread, a spreadsheet and one paralegal's memory, and the three disagree the week before filing.
Cover pages, tabs, an index, consistent file names, and a size limit that rejects the whole thing at eleven at night.
Your firm sets its own checklist. This is the shape most of them take.
Send the client a link and ask for what the case needs
Everything that arrives is read, named and filed against the request
Blurry scans, missing pages and duplicates are flagged before you see them
The readiness view says what is outstanding and who it is waiting on
Photographs become captioned exhibits and the packet builds itself
One engine
Collect the documents, work out what they are, say what is missing, organise what arrived, build the package somebody has to submit. That sequence does not change between a petition, a claim and a loan file. Only the vocabulary and the checklist do, which is why a firm that works across two of these does not need two products.
Every file is stored exactly as it arrived and is never rewritten. Anything the product produces is a new document beside the original, and you can take the whole file out whenever you want, as an archive with an index.
