Dotloop vs DealDock vs Zipform: An Honest Comparison

If you've been in real estate for more than a year, you've heard all three names: Dotloop, Zipform, DealDock. They're all described as “real estate software.” They all deal with contracts. But they're built for fundamentally different jobs — and confusing them leads to either overpaying for things you don't need or missing capabilities you actually need.

Dotloop: The document management layer

Dotloop is owned by Zillow and is one of the most widely used real estate document platforms in the country. Its core function is simple: it's a way to organize, store, and collect e-signatures on real estate documents. Think of it as Google Drive with e-signature capability built in, organized around “loops” (one loop per transaction).

Dotloop does its core job reasonably well. If you need a centralized place to store transaction documents, collect signatures from clients, and share files with co-op agents and title companies, Dotloop works.

What Dotloop doesn't do: it doesn't read your contracts. It doesn't validate fields. It doesn't extract deadlines. It doesn't send TC communications. It doesn't track milestones. Dotloop is a file cabinet with e-signature — a useful one, but a file cabinet nonetheless.

Zipform: The form creation layer

Zipform (now rebranded as Transactions) is a form library maintained by the National Association of Realtors and state associations. Its purpose is to help agents fill out standardized real estate forms correctly. You pick the form you need — purchase agreement, listing agreement, buyer representation agreement — and fill it out inside the platform.

Zipform is genuinely useful for agents who are filling out forms from scratch and want access to current, state-approved form versions. The library is comprehensive and kept up to date as forms change.

What Zipform doesn't do: anything after the form is signed. There's no transaction management, no deadline tracking, no communications, no validation. Once the form leaves Zipform, you're on your own. It also only works with forms created inside the platform — you can't upload an externally created PDF and have Zipform do anything useful with it.

DealDock: The transaction coordination layer

DealDock is built for a different moment: after the contract is signed. Upload your executed purchase agreement — from any source, any state, any form — and DealDock reads it. It validates every field, flags errors and missing items, extracts every deadline, and sets up your transaction management dashboard automatically.

From there, DealDock handles the first communications — under-contract confirmation, wire fraud warning, title company introduction — and tracks every milestone from contract to close. It's not a form library (you'll still use whatever you use to create forms) and it's not a document storage layer (though it does store your transaction documents). It's the operational layer that runs the deal.

DealDock is priced at $79/month for solo agents — unlimited transactions, no per-deal fees. For agents closing more than 2–3 deals a month, the savings over human TC fees are immediate.

Side-by-side comparison

So which one should you use?

The honest answer is: they serve different purposes and many agents will end up using two of them.

• Use Zipform: when you're filling out state-specific forms from scratch and want access to the current, approved version of every standard form in your state.
• Use Dotloop: if your brokerage requires it, or if you need a shared document storage layer that co-op agents and clients can access. It works fine for e-signatures.
• Use DealDock: for everything that happens after the contract is signed — validation, deadline tracking, TC communications, and milestone management. DealDock works with documents from Zipform, Dotloop, or any other source.
