Lost supplier invoices quietly eat your margin — unclaimed on the client bill, missing at tax time. Here's how trades keep every receipt tied to the job it belongs to.
A lost supplier invoice is more expensive than a lost photo, because it costs you twice. Once when you cannot pass the cost through to the client because you have no record of it, and again at tax time when you cannot claim it as a business expense. Multiply a handful of missed receipts across a year of jobs and it adds up to real money walking out the door — quietly, without any single dramatic moment to make you notice.
The receipts themselves are not the hard part. Suppliers hand them over readily — a paper slip at the counter, a PDF by email, a photo the merchant texts you. The hard part is that each one arrives through a different channel and none of them are attached to the job they belong to. This is how to fix that.
The core problem is not losing the paper — it's the broken link between the receipt and the job. Fix the link and the receipt stops being lost even when it is buried in an inbox.
Every receipt, no matter how it arrives, should end up in exactly one place: the job it belongs to. The way you get it there depends on the channel it came in on, but the destination is always the same.
When a supplier emails an invoice, forward it straight to the job — ideally to a job inbox address that files it automatically. That converts a message you would otherwise have to remember into a filed document in one action. If your system auto-reads forwarded emails and drops them into the right job, you never touch a folder.
Do not wait until you are back at the truck, let alone back at the office. Photograph the slip at the counter and send it to the job then and there. A paper receipt that has been photographed and filed is safe even if the original ends up as confetti in the wash.
A receipt a merchant texts you is fine for about a day, then it disappears under newer messages. Move it to the job the same day, the same way you would a site photo — see How to organize job site photos for the capture habit that makes this automatic.
When every supplier cost for a job is filed against that job, two good things happen. First, nothing gets left off the client bill — you can see the true cost of the job at a glance and mark it up correctly. Second, at tax time your deductible expenses are already sorted by job instead of scattered across three channels, so you claim everything you are entitled to.

Receipts are one part of a bigger picture. The same per-job destination should hold your quotes, permits and change orders too — that broader system is in The best way to keep track of contractor paperwork.
JobFolder gives every job its own folder that files forwarded emails and texted photos automatically — no manual sorting.
Start free — 3–5 jobs, no cardSend every receipt to a single per-job destination regardless of how it arrived: forward emailed invoices to the job, photograph paper slips at the counter, and move texted receipts out of the message thread the same day. The goal is one place per job that holds every supplier cost.
Because they arrive through different channels — paper, email, text — and none of them are automatically linked to the job. The receipt is rarely truly lost; the link between the receipt and the job is what breaks, which is why it can't be found or billed later.
Twice. You can't pass an untracked cost through to the client, so it eats your margin, and you can't claim an unrecorded expense at tax time. A few missed receipts per job adds up across a year.
Photograph it at the counter and send it straight to the job before you leave the supplier. Waiting until you're back at the truck or office is where paper slips get lost. Auto-filing a texted photo to the right job makes this a single action.
