A WhatsApp bot for mortgage brokers
that collects documents and tracks a file's status
Not every brokerage needs a full AI agent on day one. A WhatsApp bot that collects a document against a checklist, reminds a borrower before a deadline and lets them check their file's status is often enough to stop the manual chasing, built and live in one to two weeks.
Why mortgage brokers lose money today
Document collection for a loan file follows the same pattern at almost every brokerage: a borrower is asked for a list of documents, pay stubs, bank statements, tax returns, sends half of them, forgets the rest, and a loan officer or processor has to track who sent what and chase the gap manually, often during the exact window when the file is already racing a rate lock deadline.
Deadline reminders suffer the same way. A brokerage processing dozens of files at once cannot realistically track each borrower’s specific deadline and send a personal reminder by hand every time, so reminders either go out as a generic email many borrowers skim past, or do not go out consistently at all.
The third gap is visibility. A borrower who wants to know whether their file is moving, stuck on underwriting, or waiting on a document usually has to call and wait for someone to check, which is a small interruption multiplied across every active file, every week.
A fourth, easy to overlook, is where documents actually end up. Scanned pay stubs and bank statements sent by email or text scatter across inboxes and personal phones, with no single place a processor can check to confirm what has and has not arrived for a given file, which makes the first three problems harder to fix even once someone decides to fix them.
What we build for mortgage brokers
A WhatsApp bot with one job done well: collect documents against a checklist specific to the loan type, send reminders on the schedule your underwriting timeline needs, and let a borrower check their own file’s status without waiting for a reply. Uploaded documents are logged with a timestamp and matched against the checklist, so a processor can see at a glance what is still missing without opening a chat thread.
Admins get notified the moment a document arrives or a deadline passes without the expected upload, through a separate admin channel, so nothing depends on someone remembering to check. Checklists and reminder schedules are editable by your own staff through simple bot commands, no developer needed for the routine updates that come with every new loan type or lender requirement.
Typical integrations: WhatsApp Business API for the borrower-facing flow and the admin notification channel, a lightweight database for document and status tracking, and a loan-origination system or CRM export where your brokerage wants the data to live.
The bot deliberately does not try to hold a conversation. It runs a fixed sequence: here is what we need, here is what is still missing, here is your current status. That narrower scope keeps the build fast and the running cost close to zero, and it covers most of the document-logistics work that eats a processor’s week.
The bot also removes a specific source of borrower anxiety that has nothing to do with the actual loan: silence. A borrower who has not heard anything in several days during an already stressful process tends to assume something has gone wrong, and a quick, accurate status check, even “still waiting on underwriting, no action needed from you,” does more for the relationship than its simplicity suggests.
What stays with humans
The bot never confirms a rate, never estimates whether a borrower qualifies, and never answers a question about a specific loan product. Any message that reads as a question about pricing, qualification, or a loan officer’s recommendation gets flagged to an admin rather than answered, since a fixed-flow bot has no business guessing at any of those.
Price and timeline
| Model | Price | What it covers | Timeline |
|---|---|---|---|
| Agency runs it | from $900 | We build, host and maintain the bot; checklist and schedule updates included for the first month | 1 to 2 weeks |
| Full control, handover-ready | from $1,530 | Same build, plus full source, hosting handover and a written runbook for your own team | 2 to 3 weeks |
Running cost is close to zero beyond hosting, since the bot runs fixed logic rather than a language model on every message.

FAQ
What does a WhatsApp bot for a mortgage brokerage cost?
A bot with document upload, reminders and status checks is about $900 to $1,500. Adding an admin panel with loan-origination system export typically moves it toward $1,500 to $4,000. We give the exact number in a written plan after a short brief.
How is this different from the full AI agent package?
This bot runs a fixed flow: upload a document, get a reminder, check a status. It does not hold an open conversation or answer general process questions. The [AI agent for mortgage brokers](/solutions/ai-agent-for-mortgage-brokers/) adds that FAQ layer handled by a language model, for brokerages that need more than document logistics.
Can borrowers use it without installing anything new?
Yes, it runs inside WhatsApp, which most borrowers already have. There is no separate app to install during an already stressful process.
Who updates the checklists and deadline schedules?
You, through admin commands or a simple panel we build in, no developer needed for routine updates. We only get involved again if the checklist logic itself changes.
Does it handle sensitive financial documents securely?
Documents are stored on infrastructure in your name with access limited to roles you set, and we document retention so you can answer a borrower's data request. We do not route documents through any third party outside the hosting you approve.
