How to Keep Contractor Invoices and Job Sheets So the Job Can Be Re-Opened

The invoices are paid, but they sit in a shoebox, a camera-roll photo of a handwritten docket, or a mixed PDF dump for two flats. Open one folder per property, give the job a short ID, and pair quote, job sheet, invoice and dated before-and-after photos. Tag repair versus capital the day the invoice lands. Scan paper within a week. That clip is what lets you re-open the same leak, and what you can hand an accountant.

Saturday, two lets in Cardiff. Jonah empties a shoebox of paid invoices onto the kitchen table. Two plumber PDFs, same firm, no job numbers, no flat numbers that match. One handwritten docket is a WhatsApp photo. Before shots sit in the tenant thread; after shots are still on the contractor’s phone.

The risk is November: the leak comes back at the Cathays flat. There is no job sheet naming who attended, what was found, or which parts went in. The accountant cannot tell a repair from a kitchen upgrade.

The problem is a paid invoice proves money left the account. It does not prove who attended, what was found, or which parts went in — and it often does not even name the flat. Fieldwynn’s UK job-sheet template is blunt: on a landlord job the site address is frequently nobody’s address on the invoice. Typical mistake: filing the paid PDF as if it were the whole job.

How do you keep two flats from mixing in one shoebox?

Open one folder per property, named with the address or a stable property ID. Do not keep a pile labelled repairs 2026 across the portfolio. Give each job a short ID the day you instruct, or the day the first paper lands, and put that ID on every file.

Do name files with the property ID first. Bellsoph’s record-keeping checklist, updated 12 September 2026: a file called certificate.pdf is useless until you know which property it concerns. GOV.UK rental-income guidance, updated 19 March 2025, lists invoices and receipts among records you must keep. Property Tax Partners, reviewed 2 June 2026: keep records property by property.

For example, Jonah’s two Cardiff lets each get their own tab and a short ID such as JOB-2418. The site postcode on the sheet is the property, not the contractor’s billing address. Do not open one repairs dump for the whole portfolio.

What to pair in the four-clip pack?

The clip for one job ID is four pieces: quote or authorised spend, job sheet, matching invoice, and dated before-and-after photos of the same view. A job sheet is what actually happened on site — who attended, what was found, parts, time on site. Do not treat the paid invoice as that sheet.

The chain is quote → job sheet → invoice → before/after. Traddie’s job-sheet template, dated 14 July 2026: invoicing from memory is how parts fitted on the day vanish from the bill. The TLA RRA 2026 work-order record tells you to retain invoices, photos and completion evidence. Copy both the week of the visit, same angle, dated. Do not leave after shots on the contractor’s phone.

The written request that started the visit lives on the tenant repair-request process. This folder starts when the paid paperwork exists. If a later deduction needs the same invoice and photos, a copy can sit in a deposit dispute evidence pack — do not rebuild that pack here.

What to do when the contractor only texts a docket?

Save the WhatsApp photo as the invoice. The same week, chase who attended, what was found, and which parts went in, in writing. A handwritten receipt-pad can evidence payment if it is accurate, complete and readable. It still does not name the engineer or the parts.

There is no prescribed invoice format. GOV.UK tax records only asks that records stay accurate, complete and readable. In practice, a pad slip can go to an accountant as a receipt. If they will not issue a sheet, file an email with the same fields. Typical mistake: paying the final invoice on a line that says everything is fine.

When to tag repair versus capital?

Write one word on the clip or in the filename the day the invoice lands: repair or capital, or both with a split if the bill mixes them. A repair restores an asset to its original condition. Capital is adding something that was not there, altering, improving or upgrading. Do not wait until January to reconstruct maintenance £480.

GOV.UK’s rental-income page is the working test. Replacing storm-blown roof tiles is a repair; a higher-specification kitchen is capital. Keep capital records; they may reduce tax on a later sale. HMRC PIM2025: taking the roof off and adding a storey is capital. PIM2030 allows a fair split on a mixed bill.

Dated before-and-after photographs make a vague invoice defensible. For example, kitchen works £4,800 with no photos is a guess in January. Borderline jobs get a working label today and a note to ask the accountant. Do not treat this tag as tax advice.

How do you scan paper so it stays readable?

Photograph or scan the front, and the reverse if anything is printed on the back, within a week. Check the image is readable: amount, date, who, property. Name it property ID, job ID, then quote, jobsheet, invoice, before or after. Do not leave the only copy in the shoebox, WhatsApp, or the contractor’s sent items.

GOV.UK tax records says there are no rules on how you keep records — paper, digitally, or software — only that they stay readable. HMRC CH13400: a full copy, including the reverse, in a legible form satisfies the duty to preserve. Same-day scan is best; a week is the catch-up. Do not wait until January.

Which folder can you actually hand an accountant?

Success bar: Saturday opens one folder — each job has an ID, the four clips are paired, repair versus capital is tagged, and paper is scanned. An accountant can open it without reconstructing January from memory.

Keep the clip for the GOV.UK window: at least five years after the 31 January deadline for that tax year. Property Tax Partners: 2026/27 records filed by 31 January 2028 stay until 31 January 2033. Company landlords and VAT invoices often run six years. If this invoice is a leak, keep it here and drop a copy into the claim folder.

Workflow: property folder → job ID → quote → job sheet → invoice → before/after → repair or capital tag → scan within a week. An IziRento workspace can hold those records. Verify that checklist, then stop.
