Client
Fast Help, a water and fire restoration company in St. Louis, Missouri, USA. Owner Sean Collins runs a team of about 10 people across admin, office and field crew. Their jobs are burst pipes, leaks, sewage clean-ups, mold and dry-outs in homes around St. Louis.
Problem
Restoration work is proof-heavy. Every job needs photos, a signed work authorization, drying logs, insurance details and an invoice. Insurers want all of it.
By October 2026 the business had 223 jobs and 16,536 photos sitting in an earlier app. Sean had already chosen a custom app over off-the-shelf photo tools. In his words: "I want the ability to customize things I want, not rely on what others [think] want."
- Photos were the heaviest part. One job alone had 385 photos (738 MB). Big photo reports were too large to email.
- Paperwork was spread out. Signatures, dry logs, insurance claims and invoices each needed their own step.
- Records had drifted. Some jobs had blank or duplicate job numbers.
- Costs were climbing. Keeping the photos where they were would have cost about $89 to $99 a month, against $25 a month now. (estimated)
What we built
We understood the problem, then picked the platform that fits. We built a custom field app the business owns, moved every old record across, and put it on their own web address. It installs on the phone home screen and works just as well on a computer in the office.
- Photos that never get lost. The crew takes photos on site. They upload in the background, retry on bad signal, and carry on after the phone goes offline. "Before" and "After" photos stay apart.
- Photo reports in one tap. The report builds itself and lands in the office inbox, split into parts small enough to email, even for 385-photo jobs.
- Signatures on the spot or by text. The client signs on the tech's phone, or gets a secure link by text or email that works for 72 hours.
- Everything about a job in one place. Contacts, insurance claims, drying logs, documents, letters and invoices, each on its own tab.
- Money at a glance. Open balances, outstanding totals and unsigned authorizations sit on the home screen. Invoices go to their accounting software.
- A portal for clients. Homeowners sign in with their email to review and sign, see their invoice and shared documents.
Before
Jobs, photos and paperwork lived in an earlier app the business had outgrown, with photo reports too big to send and costs rising.
After
The crew photographs, logs and gets signatures from their phone, and the office sees every job, document and balance in one place.
Results
- Every record moved across. 223 jobs, 16,536 photos, 2,422 invoice lines, 607 drying log entries and 103 insurance claims. Every photo was checked against its original.
- Messy records fixed. Blank and duplicate job numbers were renumbered cleanly during the move.
- Large photo reports now send themselves. A 385-photo job arrives by email in about 6 parts, built in the background so the crew can close the app.
- Lower running cost. Photo storage on a $25 monthly plan instead of an estimated $89 to $99. (estimated)
- Daily use. Sean says he uses his custom app "20 times a day".
