Lever arch vs box file · the real decision.
Lever arch is for documents you flip through more than once a year: contracts you renew, monthly reports, client files you actually consult. Two-ring mechanism, spine label, 75mm capacity holds about 500 sheets. The lever mechanism is the point — you can add or remove a single sheet without disturbing the rest, which matters when you file continuously.
Box files are for documents that go in once and get retrieved only when someone asks. Insurance policies. Old warranty certificates. HMRC correspondence from four years ago. Flat stack, no rings, hinged lid. Slightly cheaper per box, much cheaper per document if you never open it. If you are filing it for compliance and nobody will look at it again, use a box file.
The colour coding that actually works.
A colour code works only if the reader can decode it without thinking. That means: one axis, four to six colours maximum, and the colour has to map to the category most people already associate with it. So red for finance and payroll (money, red ink, the associations line up). Blue for legal and contracts. Green for HR and payroll — wait, no, HR needs its own colour, yellow. Save green for "live projects" or the current financial year. Grey or black for archive.
The failure mode is a two-axis scheme where colour codes department and a coloured spine label codes year. Nobody reads both. You end up with a wall of files where someone made a thoughtful decision about the spine label and nobody knew the thoughtful decision. Pick one axis. Almost always: department.
The hot-desk problem.
In a hot-desk office, the filing shelf is the only fixed point. That has three implications:
- Label every file on both spine and top-front. Someone looking from below reads the spine; someone looking from above reads the top edge. Lever arch top edges are the most-ignored real estate in office filing.
- Fix the shelf order in writing, on the shelf. A printed index taped to the shelf edge tells someone new that finance goes A–D and HR goes E–H. Do not rely on institutional memory; institutional memory quits.
- Have a "pending" tray at desk height. Half your filing problem is documents that are on their way to filing but no seat has responsibility for them. A pending tray at every desk, with a Friday rule to empty it into its file, is the entire fix.
What audit season needs.
An auditor turns up expecting: bank statements for the year (monthly, in order); invoices out (numerically, matching the ledger); invoices in with delivery notes attached; PAYE and VAT submission acknowledgements; and one signed board minute per financial decision above the threshold your policy sets. That is it. Everything else the auditor asks for is a bonus round.
So the filing system that survives audit is a set of six lever arch files labelled to that list, one per compliance year, kept together on a shelf reachable without a ladder. Everything else can be in box files or digital. The mistake is trying to file everything to audit standard.
A working starter list.
- 10 lever arch files, 75mm, coloured spine.
- 6 lever arch files, 75mm, black (archive).
- 10 box files, foolscap, black.
- 500 A4 punched pockets (100 micron, the ones that don't tear).
- A pack of 30 dividers, mixed colours, numeric and alpha tabs.
- Two label makers — one at the shelf, one at reception.
That covers a small office for a year of live filing plus a year of archive rollover. Restock the punched pockets and dividers in month nine; the lever arch and box files last three to five years.
