The fastest way to collect year-end documents from clients is one upload link per client, pointing at that client's folder, sent with a short list of exactly what you need. No attachments, no "can you resend that", no statements arriving in a colleague's inbox. The client uploads without creating an account, and every file lands where you will look for it.
I run Yungle, which does this, so read the rest with that in mind. The method works with any tool that has proper upload links.
Why year-end collection goes wrong
Every practice knows the pattern. You email a checklist in January. Documents arrive in March, in pieces: two bank statements attached to one email, a phone photo of a receipt in another, a payroll export sent to the wrong partner, and one enormous PDF that the mail server quietly refused.
None of that is the client being difficult. It is the channel. Email was never built for bulk documents, it has a size ceiling around 25 MB, and it scatters one client's paperwork across several inboxes. Every piece then has to be found, saved, renamed and filed by hand.
One link per client, one folder per link
The fix is to reverse the direction. Instead of asking clients to send things to you, give each of them a place to put things in.
A file request is exactly that: a link that accepts uploads and nothing else. The client opens it, drops in their files, and is done. They cannot see what anyone else sent, they do not need an account, and whatever they upload is checked for viruses before it reaches you.
Point each client's link at their own folder — Clients/De Vries BV/2026 — and the filing is done at the moment of upload.
Tell them exactly what you need
A link does not replace the checklist; it gives it somewhere to go. Keep it short and concrete:
- Bank statements for every account, 1 January to 31 December.
- Sales and purchase invoices, or an export from your bookkeeping software.
- Payroll summaries, if you have staff.
- Anything unusual: a large purchase, a loan, a vehicle.
Put the list and the link in one message. Clients finish things when the next step is obvious; they stall when it involves finding an old email thread.
Keep the collection separate from the delivery
Collecting and delivering are different jobs and deserve different links. The upload link gathers the client's paperwork; the finished accounts go back as a normal transfer, or in a folder the client can return to.
Keeping them apart also keeps the permissions clean. The request link can only receive. Nothing you place in the client's folder becomes visible through it, which is the point: a link you sent to a client should never become a window into your files.
Security that is proportionate
Year-end documents are personal and financial data, and clients are right to ask where they go. Three honest answers matter more than a badge:
Where it is stored. Yungle's servers are in Germany, run by a European company. Nightly backups are kept in EU-jurisdiction storage at a second provider.
How it is protected. Every file is always encrypted with its own key. Those keys are held by Yungle, which is what makes virus scanning and previews possible — for a file that even we must not be able to read, there is an opt-in end-to-end encrypted transfer.
What you agree to. There is a published data processing agreement, and the choice of tool, retention and your own obligations remain yours to assess. The page for accountants sets out what stays your responsibility.
Close the loop
Collection ends when you confirm it. A short reply — "Got everything, thank you" — saves the client from wondering and saves you the follow-up call. If something is missing, send the same link again with one line; they already know how it works.
After the year closes, decide how long the folder should live. How long to keep client files covers the reasoning, and the answer is rarely "forever by default".
The short version
- One request link per client, pointing at their own folder.
- A short, concrete list of what you need, in the same message as the link.
- Deliveries go back on a separate link.
- Know where the files are stored, and be able to say so.
- Decide retention on purpose.
If sensitive documents also flow the other way — signed returns, payroll, contracts — sending sensitive documents to clients covers that direction.
