Verbal approval is easy to forget—and hard to invoice.
A homeowner asks for extra work. Your crew handles it. Weeks later, the photos are buried in a camera roll, the details are in a text thread, and the customer questions the charge. Margn helps you document the change while everyone still agrees on what happened.

Who it’s for
Built for the contractor who is also the estimator, project manager, and office.
Margn is designed for 1–10 person residential crews that work directly with homeowners and regularly handle changes in scope. Especially useful when additional work is discussed at the job site instead of from an office.

Trust and limitations
Useful records without legal overpromises.
A clearer record—not a payment guarantee
Margn helps organize job photos, customer approvals, signatures, change orders, and invoices. It does not guarantee payment, replace your contract, or provide legal advice.
Customer location
Margn may request approximate location during an approval to help document where the approval occurred. It does not continuously track the customer.
Customer experience
The customer does not need to download Margn. They receive a secure review link by text and can approve from their phone.
Why Margn
Built around the moments when contractors lose track of money they already earned.
Margn is being built for small residential contractors who make important decisions while the job is moving. The goal is simple: make it easier to document changes, get customer approval, and keep the record connected to the invoice.

FAQ
Questions before you try Margn
Does the homeowner need to download an app?
No. The homeowner receives a secure review link by text and can review, approve, and sign from their phone.
How does the homeowner approve a change order?
They open the review link, see the added work, price, and photos, then provide a typed signature through the approval page.
What information is saved with an approval?
Margn stores the approval decision, typed signature, approval time, related job photos, change order details, and available approval metadata.
Can I use Margn for quotes and invoices?
Yes. Quotes, payment milestones, approvals, invoices, PDFs, and related job records are functioning in the current private beta.
Can Margn guarantee that a customer will pay?
No. Margn helps create a clearer approval record, but it does not guarantee payment or eliminate all disputes.
Is Margn a replacement for my contract or attorney?
No. Margn is a job-documentation tool. It does not replace your contract, legal advice, or professional judgment.
Why might Margn request location during approval?
Approximate location can help document where an approval occurred. The approval page requests it for that approval event, not continuous tracking.
What happens to my records if I cancel?
The long-term cancellation and record-retention policy needs attorney review before it is published.
How much does Margn cost?
Margn is onboarding founding contractors now. The Founding rate is $49.99 per month once subscription billing is available.
