Group Trip Document Storage: How Lumela Keeps Everyone's Files in One Place

Tickets, IDs, and hotel confirmations scattered across everyone's phone? Lumela stores trip documents in one shared place every group member can open.

Key takeaways

  • Lumela lets a whole group upload and access shared trip documents — tickets, IDs, confirmations — not just one person's phone.
  • Files up to 15MB, no restrictive file-type list, and no separate invite step — being in the group unlocks the document.
  • Receipts can attach directly to a logged expense, keeping proof of purchase with the expense record.
  • It's not OCR or auto-fill — just a shared, group-visible place for the paperwork every trip generates.
  • Upload confirmations as soon as you book, not the night before you need them.

Every group trip has the same moment: someone needs the hotel confirmation, or a scan of a passport, or the ferry ticket — and it's buried in one person's email, another person's WhatsApp thread, and a third person's camera roll. Nobody has all of it, and the person who does is usually asleep or offline. Lumela solves this by giving the group one shared place to keep trip documents, so anyone can find what they need without texting "hey can you resend that."

The problem with scattering documents across apps#

A typical trip generates a real pile of paperwork: flight and train tickets, hotel and Airbnb confirmations, ID and passport scans (for border crossings or hostel check-in), insurance documents, rental car agreements, receipts for shared expenses. None of it lives in one app by default — it's split across whichever app each person happened to book through, plus screenshots forwarded in a group chat that scrolls out of reach within a day. When something goes wrong (a missed check-in time, a lost paper ticket, a border officer asking for proof of onward travel), the group loses time hunting for a file that one specific phone has, somewhere.

How Lumela keeps it in one place#

Inside a Lumela group, documents can be uploaded and shared with the whole group, not just kept on one person's phone. Upload a file — a PDF, a photo of a ticket, an ID scan, anything, there's no restrictive file-type list — and tag it to the group. From that point, every current member of the group can open and view it, the same way everyone can already see the group's live locations or shared expenses. There's no separate invite or permission step: being in the group is what unlocks the document.

Files max out at 15MB each, which comfortably covers scanned documents, PDFs, and photos without turning the app into general cloud storage. Receipts get their own handling too — attach one directly to a logged expense, and it travels with that expense's record rather than getting lost in a generic camera roll, which pairs naturally with how Lumela keeps trip expenses fair when someone questions a charge later.

To be clear about what this isn't: it's not an OCR tool that reads your passport or auto-fills a form, and there's no elaborate tagging system beyond a few practical folders (general documents, receipts, and a couple of others used internally for things like profile photos). It's closer to a shared drawer than a smart assistant — but a shared drawer that everyone in the group can actually open is already a real upgrade over five separate photo libraries.

Getting a document in front of the whole group#

  1. Open the group and go to its documents area.
  2. Upload the file — a confirmation email PDF, a photo of a printed ticket, whatever format it's already in.
  3. Leave it tagged to the group (the default) so every current member can see it, or keep it personal if it's just for you.
  4. If it's a receipt for something the group is splitting, attach it to that expense instead, so proof of purchase and the expense record stay together.

Practical tip

Upload the important stuff — accommodation confirmations, transport tickets, ID scans for border crossings — as soon as you book it, not the night before you need it. It takes ten seconds when you're already looking at the confirmation email, and it means nobody's digging through their inbox at a hostel front desk with bad wifi.

Lumela isn't trying to replace your email or your bank's app — it's not where you manage bookings or payments. What it does is make sure that once something's booked, everyone in the group who might actually need proof of it — a ticket, a confirmation, an ID — can get to it without waiting on whoever booked it to wake up and check their phone.
