Year-End Billing Checklist for White-Label Client Work: 2027 Rates, Prepayments and 1099s

The last weeks of the year are when many agencies and coaches review what they charge for white-label work, wrap up open client projects and get their paperwork ready for tax season. Starting now, in mid-October, gives clients fair notice of any changes and leaves time to sort out records before January. This checklist covers billing and administration; it is general information, not tax or legal advice, so confirm the details with your accountant. Each section ends with steps you can complete in an afternoon.

1. Decide on 2027 Rates and Give Notice Early

If you plan to change package prices or retainer fees for 2027, check each client agreement for a notice period or renewal clause before you announce anything. A short, clear notice works best:

Which packages or retainers change, and the new figures
The date the new rates take effect
Whether work already booked or prepaid keeps the current rate
Who to contact with questions

As an example only: an agency billing a $1,500 monthly retainer might write in November that the fee becomes $1,650 for invoices dated from February 1, 2027, honoring the current rate for January. Your own figures and timing will depend on your contracts.

2. Understand How Year-End Prepayments Are Counted

Clients sometimes ask to pay in December for work delivered in January. How that payment is counted for tax purposes depends on your accounting method. IRS Publication 538 (revised January 2022) explains that under the cash method you include income in the year you actually or constructively receive it, and that income is constructively received when it is credited to your account or made available to you without restriction. Under the accrual method, the publication says advance payments are generally income in the year received, although some businesses can elect to defer qualifying advance payments to the next year under specific conditions.

Before accepting a large prepayment, ask your accountant how it would be treated in your case, and make sure the invoice states clearly what the payment covers and when the work will be delivered.

Wording the Invoice for a Prepayment

Describe the deliverables the payment covers, not just “January work”
State the expected delivery dates or milestones
Say what happens to the payment if the project is canceled or postponed, in line with your agreement
Keep the invoice date and the payment date accurate; do not backdate or postdate either

3. Close Out Open Projects Cleanly

Send final invoices for completed deliverables before the holidays.
Confirm in writing which revisions are still included and when that window closes.
Deliver final files and record the delivery date for each client.
Note any unused prepaid hours or credits and how they carry into 2027 under your agreement.

4. Prepare for Form 1099-NEC if You Paid Subcontractors

Many white-label agencies use freelance writers, designers or developers. According to the IRS Instructions for Forms 1099-MISC and 1099-NEC (revised December 2026), the reporting threshold for certain payments rises to $2,000 for tax years beginning after 2025, and Form 1099-NEC must be filed by January 31. For 2026 payments, January 31, 2027 falls on a Sunday; the instructions say a due date on a weekend moves to the next business day.

The same instructions note that payments made by credit card or through certain payment networks are reported by the payment settlement entity on Form 1099-K, not by you on Form 1099-NEC, and that payments to corporations generally do not need a form, with exceptions. An IRS tax tip also reminds businesses that they need each payee’s taxpayer identification number to report correctly. Practical steps now:

List every contractor you paid in 2026 and how you paid them.
Collect any missing taxpayer details before the January rush.
Check with your accountant which payments need a form.

5. Tidy Your Records for Tax Season

Match client invoices to payments received, including any Form 1099-K amounts you expect.
Export processor and bank statements for the full year.
File signed agreements, change orders and rate notices by client.
Note open questions for your accountant in one place.

Working through these steps in October and November leaves December free for client delivery, and gives everyone involved, from clients to subcontractors, enough notice to plan their own year-end.
