Records That Survive Two Years
A record you cannot find is a record you do not have.
For a software-side reference alongside this discussion of invoicing, records, and payment administration, Monitask has this resource.
Most small firms keep more than enough evidence and can produce almost none of it at the moment it matters, because it is spread across a phone, two email accounts, a notebook and a folder on a laptop that was replaced.
What a dispute actually needs
The quote, in the version that was accepted.
The acceptance — the message, whatever form it took.
Every variation, with its date and the confirmation.
The invoice, and any corrected version with the explanation.
Photographs, particularly the ones taken before you started.
And the correspondence in between, in order.
Six things. Most firms have all six and can produce two.
Where they should live
One place per job, not one place per document type.
A folder named with the job reference and the customer, containing everything. Not the quotes in one place, invoices in another and photographs on a phone — that organisation is convenient when filing and useless when retrieving.
Cloud storage that is not tied to a device. A laptop that dies takes local folders with it, and the moment you need the records is frequently a moment when something else has also gone wrong.
And an email account that is yours rather than one supplied by an internet provider you may leave.
The phone problem
In trades, a substantial part of the record lives in text messages and photographs on a phone.
Phones are lost, stolen, dropped, replaced and wiped. Messaging apps are not archives and their backups are not reliable for this purpose.
Move what matters off the phone weekly. Photographs to the job folder, important messages screenshotted and saved with them.
Ten minutes a week, and it converts the most fragile part of the record into the same store as everything else.
How long
Longer than you think, and longer than tax requires.
Limitation periods for contract claims run to several years in most jurisdictions, and vary by whether the contract was written or verbal. Check the position where you work — this is not legal advice and the periods differ substantially.
The practical answer for a small firm is to keep everything, because the storage costs nothing and the alternative is judging in advance which job will be disputed, which nobody can do.
Naming things so they can be found
A convention, applied consistently, beats a filing system nobody maintains.
Job reference, customer name, date. In that order, in the folder name and in every file inside it.
"214-Hendricks-quote-2026-03-03.pdf" is findable by search two years later. "quote final v2 (1).pdf" is not, and it is what most folders contain.
The convention matters more than which convention.
What this is for beyond disputes
Pricing the next job. What the last one actually took is in the records, and it is the only honest input to an estimate.
Warranty and callbacks. A customer ringing about work from eighteen months ago is answered in a minute if the job file exists.
And selling the business, or handing it on. A firm whose records are in one person's head has value only while that person is present.
The backup that is not one
A folder synced to a cloud service is not a backup.
Deletion syncs. Corruption syncs. An account lost to a forgotten password takes everything with it, and recovery processes are designed for people who can prove ownership, which is harder than it sounds at a distance of two years.
One copy elsewhere, on a drive or a second service, updated occasionally. Not continuously — the point is that it does not receive whatever went wrong.
Check once a year that it opens. A backup nobody has ever restored from is an assumption.
When somebody else keeps them
An accountant or a bookkeeper holds some of this and not the rest.
They have the invoices and the payments. They do not have the quote, the variations, the photographs or the correspondence — which is most of what a dispute needs.
Do not assume the accounting record is the job record. It is the financial half, and the half that gets contested is the other one.
And know what happens if the relationship ends. Data held by a provider is a question worth asking before you need the answer, and it applies to people as well as to software.
What to do at the end of every job
Five minutes, while it is still open.
Move the photographs off the phone. Save the final invoice into the folder. Put a one-line note at the top of the folder saying what the job was and how it ended — "kitchen rewire plus two variations, paid in full 14 May, no snags."
That line is the thing that makes the folder useful without opening everything in it, and it takes twenty seconds while the job is fresh.
Doing it later means reconstructing it, and reconstruction is where records become approximate.
The record of what you were told
The weakest part of most job files.
Verbal instructions, site conversations, promises about access and materials — none of it is written down unless somebody decides to write it down.
The habit of confirming by message produces this record as a by-product, which is the main practical reason to do it beyond the contractual one.
A file with the correspondence in it tells the story of the job. A file with only the quote and the invoice tells you the numbers and nothing about how they were arrived at.
The short version
- A record you cannot find is a record you do not have, and most firms have the evidence and cannot produce it
- Six things: the accepted quote, the acceptance, every variation, the invoice and any correction, photographs, and the correspondence
- One folder per job containing everything, in cloud storage not tied to a device, under an email account that is yours
- Move photographs and important messages off the phone weekly, since messaging apps are not archives
- Limitation periods run to several years and vary by jurisdiction, so keep everything rather than judging which job will be disputed
- A naming convention applied consistently is what makes any of it findable, and which convention matters less than having one
