Four documents cover nearly everything anyone will ask you for later: the signed agreement, the monthly invoice or payout statement, the bank line showing the credit, and a dated log of what the account was used for. Each answers a different question from a different person — a tax preparer, a loan underwriter, or the company itself if you ever disagree about what went out from your profile. Keeping them is about ten minutes a month. Reconstructing them a year later is the part people find impossible, which is why this belongs on payout number one rather than payout number twelve.
1. The signed agreement
Keep the executed copy, with signatures and a date, somewhere you will still find it in three years. Not the draft you were emailed first, not a screenshot of a clause, and not a link to a document hosted somewhere you may lose access to. Download it.
This settles every dispute about what was agreed: the fee, the term, the notice either side must give, what may and may not be sent from your account, whether there is a blocklist, and how you pause or stop. If the arrangement is amended — a fee change, an extension, a new category of outreach — save the amendment alongside the original rather than replacing it. You want the chain, not the latest version. Your invoices reference it, your accountant reads it to classify the income, and your log only makes sense against it.
2. The monthly invoice or payout statement
This is what turns a bank credit into explained income. Without it, a transfer from a company name is just a transfer from a company name.
A usable statement shows the period covered, the amount, the paying entity's full legal name, and a reference back to the agreement. If your counterparty issues one, save it the day it arrives. If nothing arrives, raise your own invoice and send it — a payer paying you properly will have no objection, and a dated document now exists.
If a company paying you every month will not produce a statement, treat that as information about the company rather than a filing inconvenience. It belongs with the other things worth asking before you sign.
3. The bank credit line
The credit in your bank statement is the only one of the four that a third party created. That independence is why it carries weight with anyone reviewing your income. Download it as a PDF each month rather than trusting your bank to keep history indefinitely; the statements you need are always the old ones.
The single change that does most of the work: route the payouts into a separate account. Not necessarily a business account — a second ordinary account that receives this money and nothing else. Every statement from it becomes a clean, chronological record of this income with no personal spending mixed in. You stop highlighting lines in a statement full of groceries, and if you are asked to evidence this income you hand over one document instead of assembling twelve.
4. A dated log of what the account was used for
This is the one nobody keeps and the one that matters most if something goes wrong. The other three are about money. This one is about your account. A log is a plain text file with dated entries, a few lines each:
- The date and the period it covers
- What kind of outreach ran, and for which client or campaign, if you are told
- Which message templates you approved, or a note that they were unchanged
- Any names or companies added to the blocklist, and when
- Any pause you asked for, the reason, and when it took effect
- Anything unusual: a complaint, a warning notice, an unexpected login prompt
It protects you where argument after the fact is hardest. If a former colleague says they received something odd from you, you can say what was running that week. If the account is restricted, you have a timeline instead of a memory. If the company says a message was approved and you remember refusing it, one of you has a dated note.
What each document actually protects you from
| Document | What it proves | Who asks for it |
|---|---|---|
| Signed agreement | What both sides committed to | Accountant, lawyer, the company in a dispute |
| Invoice or payout statement | That the credit is income from a named source | Tax preparer, loan underwriter |
| Bank credit line | That the money arrived, verified by a third party | Underwriter, tax authority |
| Dated use log | What ran on your account, and when | You first; the company, in a disagreement |
The ten-minute monthly routine
- Save the payout statement the day it lands, named with the year and month so the folder sorts itself.
- Download the bank statement for the account the payout went into.
- Add one dated entry to the log: what ran, what you approved, anything you blocked or paused.
- Once a quarter, copy the folder somewhere else. A folder on one laptop is one spilled drink from not existing.
Name files consistently: something like 2026-09-statement still makes sense in four years, which is the only test that matters.
If you have kept nothing so far
Most of it is recoverable in an hour. Bank statements are usually downloadable for at least the past year. Ask your counterparty for copies of past payout statements — a company running this properly can regenerate them — and request a fresh copy of the signed agreement if yours is lost. The log is the only one you cannot backfill, so do not invent it: start it today with a line saying so.
While you are at it, re-read what you agreed to. The terms and the security page describe the controls meant to be in place — the blocklist, the approval step, your ability to stop — and a log is only as useful as the controls it records you using. LinkedIn's User Agreement asks members not to share their account or let anyone else use it, and an account can be restricted. Records do not change that. They change how well you can account for your own decisions if it happens.
If you are still deciding rather than already being paid, settle this before you apply, not after.
Common questions
How long should I keep all of this?
Ask your accountant, because retention periods are set locally. As a default, keep everything for as long as your country requires tax records plus a year, and keep the signed agreement indefinitely — one file, and the document most likely to matter after the arrangement ends.
Is a screenshot enough?
For the log, yes. For the agreement, the statements and the bank lines, no. Screenshots are easy to dispute. Download the PDF, which carries dates and issuer details a cropped image does not.
Do I need to log every individual message sent from my account?
No, and trying will mean you stop after two weeks. Log at the level of campaigns and approvals: what ran, what you approved, what you blocked. The exception is anything that felt wrong — log that on the day, in the words you would use to explain it.
What if the company will not give me a payout statement?
Raise your own invoice and email it to them, so a dated document exists either way. Then weigh the refusal as a signal: a counterparty uncomfortable putting a monthly amount in writing is telling you how the rest will go.
