Home warranty service calls after closing, with no internet

Last updated 3 November 2026.

Short answer: keep one record per home and one per trade, and log each service call as a row that points at both. Open a home and you see every call on it; open a trade and you see every call they still owe you. It works on a laptop at a house that has no internet yet. If you need it on a phone with no signal, read where this is honest first.

On the Fine Homebuilding forum a builder asked for “a computer driven way to keep track of service calls after a house closes.” Their way at the time: “I copy work orders to the various trades & fax them to them but it's a lot of work & not very efficient.” The one reply said nothing ready-made existed and offered to build it in FileMaker. (The thread, October 2005, read 3 November 2026.)

The job has not changed much since. A buyer calls about a sticking door or a dripping valve, someone writes it down, and the hard part is knowing which calls are still open and who has them.

How the lists fit together

A home's page lists every call on it, open and closed. A trade's page lists theirs, so the plumber's open calls are one click, not a pile of faxes. Sort calls by status and date reported and the oldest open one is at the top.

A call list that lives on the laptop

Bionic Forms builds a small app from a spreadsheet or a sentence, such as “track warranty service calls on the homes we built and which trade has each one”. Our desktop app for Windows, macOS or Linux keeps a full, encrypted copy on the computer. With no connection at all you can:

• Log a call at the house, with the room, what is wrong and the trade.
• Attach a photo of the crack or the stain (files on records).
• Print a call as a work order page to hand over (how printing works).
• Search and sort: every open call, every call on lot 14, every call the drywaller has.

When the laptop finds a connection again, the changes go up by themselves, so the office computer sees the same list. People in the office can work in a browser.

Telling the trade

Instead of faxing, a workflow can email the trade named on a call when it is assigned, with the address and the problem in the message. You write it as a sentence, such as “when a call is assigned, email the trade”. Two things to know: an email to a trade outside your own team needs the Business plan, and any email needs a connection to go out.

Getting your list in

If you already keep a spreadsheet of calls, drop it on our home page. A column with the address and a column with the trade can become links to the home and the trade. Free covers unlimited apps and 10,000 entries per app.

Where this is honest

• No offline phone app yet. Offline is the desktop app only. On a phone, ours runs in the browser and needs a signal. If your supers log calls on phones at sites with no signal, an offline phone app made for builders will suit you better today.
• No buyer portal. Buyers do not log in to see their calls. A public form can take a buyer's request as a new call, and you pick the home on it after.
• No warranty clock. Warranty end is a date you sort by. Nothing counts down the days for you.
• Set it up while you have a connection. The AI that builds the app runs on our server. Using it afterwards does not need one.
• We are small and pre-launch. We say plainly which parts are not finished, and your data can always be exported again.
