How to organise evidence for a complaint

1. 1.Gather everything in one folder first

   Before sorting anything, pull every email, letter, text message, invoice, photo and note into a single folder on your computer or phone. Do not filter at this stage; it is easier to remove irrelevant items later than to remember where something was weeks afterwards.

2. 2.Keep originals separate from working copies

   Copy the folder before you start editing, cropping or annotating anything. Work only on the copies, so you always have an unaltered version of each document if anyone later asks how a file was produced.

3. 3.Rename files with a consistent date format

   Use a format such as YYYY-MM-DD-short-description.pdf, for example 2024-03-14-invoice-dispute.pdf. Consistent naming means your files sort into date order automatically in any folder view.

4. 4.List every document with its date and source

   Build a simple index, even a spreadsheet with three columns: date, file name, and a one-line description of what the document shows. This index becomes the backbone of your complaint and lets you check nothing is missing.

5. 5.Put everything in chronological order

   Arrange your indexed items from earliest to latest. A clear timeline is usually the single most persuasive thing you can hand to a complaints handler, because it shows how the situation developed rather than presenting isolated grievances.

6. 6.Flag contradictions and gaps as you go

   Note any point where two documents disagree, such as different dates for the same event or a verbal promise that is not reflected in writing. Also note any period where you are missing documentation, since being upfront about gaps looks more credible than hiding them.

7. 7.Write a short factual summary

   Draft a plain, dated account of what happened in no more than a page, referring to your indexed documents by name where relevant. Stick to facts you can support with evidence and avoid emotive language, which tends to weaken rather than strengthen a complaint.

8. 8.State clearly what outcome you want

   End your summary with a specific, reasonable request, such as a refund, a repair, or a written explanation. Complaints handlers respond faster to a clear ask than to an open-ended account of frustration.

9. 9.Keep a copy of the complaint as sent

   Save the final version you submit, along with the date and method of sending, in the same folder. If the matter escalates later, you will need to show exactly what was said and when.

10. 10.Consider a structured report for larger disputes

    If you have many documents covering months of correspondence, a tool such as TraceFolio can turn them into a structured report with a timeline and source references in minutes, which is useful when you need to hand a complaint to a manager, ombudsman or solicitor quickly.

Imagine a dispute with a builder over unfinished work. You have sixteen emails, four photos of the site, a signed quote, and two text messages agreeing a revised date. Rather than forwarding all of this as a bundle, you would create a folder, rename each file with its date, list them in a simple spreadsheet, and then write a one-page summary: what was agreed, what was delivered, where the two differ, and what you now want (completion by a set date, or a partial refund).

The person reading your complaint, whether a manager, an ombudsman, or a solicitor, can then check your summary against the underlying documents in minutes rather than having to reconstruct the story themselves from a scattered inbox.

The most common mistake is submitting a complaint as an emotional narrative with no dated evidence attached, which makes it hard for anyone to verify what actually happened.

• Forwarding an entire email thread instead of extracting the relevant messages
• Failing to date screenshots, especially of text messages or chat apps
• Editing an original document instead of working from a copy
• Leaving out inconvenient facts, which can undermine credibility if they surface later

Once your evidence is organised, decide who the complaint should go to first: the organisation itself, a trade body, or an ombudsman. Most formal complaints processes expect you to try the organisation directly before escalating, so check their published complaints procedure for time limits and required steps.

If your organised evidence still leaves genuine gaps, for example a missing invoice or an unanswered email, note this openly in your summary rather than guessing at what it might have said.

TraceFolio accepts up to 20 files in PDF, DOCX, TXT or image format, including scanned or photographed documents read with OCR, and turns them into a report containing an executive summary, key facts, important dates, a chronological timeline, contradictions and inconsistencies, and source references for each finding.

This does not replace your own judgement about the dispute, and it does not prove that any document is genuine or that a claim is true; it simply organises what you have uploaded and shows exactly where each finding came from, which can save considerable time when a complaint involves many documents.
