An invoice is a clear request for payment. It should record the deal you and the client already made, not introduce a new price or surprise terms after the work is finished.

Before you begin, agree on the scope, price, currency, billing schedule, payment route, and due date in writing. When it is time to invoice, match those terms exactly and make the document easy for the client’s accounts person to approve.

This guide provides an operational template, not a jurisdiction-specific tax invoice or legal contract. Required wording, tax identifiers, numbering, electronic-invoice systems, and currency rules vary. Check the rules where you and the client operate, especially if you are registered for VAT, GST, sales tax, or a similar regime.

Set the price first with How to Set Your VA Rates as a Beginner, then confirm the payment route in How to Get Paid as a Virtual Assistant. For a local PHP route, check the GCash setup guide. For a client sending USD to a Philippine bank, review the RCBC US Dollar account guide before putting account details on the invoice.

What a useful invoice contains

As a practical baseline, include:

  • a unique invoice number;
  • the invoice date and exact payment due date;
  • your name or registered business name and required contact details;
  • the client’s correct legal or business name, contact, and billing address if required;
  • the service period and a clear description of the work;
  • quantity or hours, rate, line amount, subtotal, tax if applicable, and total;
  • the invoice currency written explicitly, such as USD rather than only $;
  • the agreed payment method and accurate payment instructions;
  • any purchase order, contract, project, or tax reference the client requires;
  • a short restatement of the agreed payment terms.

The UK government’s invoice guidance requires details such as a unique number, supplier and customer information, service and invoice dates, a description, amounts, applicable VAT, and the total. That is a useful cross-check, but it does not replace the rules in your country. Some jurisdictions or clients require additional fields or a government invoicing portal.

Before sending, ask: Could a person who was not in the project approve this invoice without coming back to ask what it is for?

under the service agreement dated [date].

The dates and prices above are examples, not recommended terms or rates. If tax does not apply, follow local rules on whether to show a zero line, omit it, or add a required exemption note.

Do not put account passwords, one-time codes, full identity documents, or unnecessary personal data on an invoice. When payment instructions change, verify them through a second trusted channel; believable email messages are often used in invoice-redirection fraud.

Number invoices consistently

Choose a sequence you can continue, such as VA-2026-001, VA-2026-002, and so on. Do not reuse a number for a different invoice. If you need to correct one, keep the original record and follow your local rules for a corrected invoice or credit note.

A simple file structure might be:

2026
  Client Name
    Agreement
    Time records
    Deliverables
    Invoices
      VA-2026-001-sent.pdf
      VA-2026-001-payment-confirmation.pdf

Keep the sent invoice, agreement, time record, delivery evidence, payment confirmation, and any correction together. The US IRS lists invoices, receipts, deposit information, and proof of payment as supporting business records. Other tax authorities set their own requirements and retention periods.

Write payment terms a client can follow

“Please pay soon” is not a payment term. Settle these questions in the agreement and repeat the essentials on the invoice:

  1. When is the invoice sent? Upfront, weekly, twice monthly, monthly, or at a milestone?
  2. When is it due? What is the exact date, and are calendar or business days used?
  3. What triggers payment? Invoice receipt, delivery, approval, or milestone submission?
  4. Which currency and method apply? Who initiates the transfer, and where does it go?
  5. Who pays which fees? Which sending, receiving, and conversion costs were agreed?
  6. How are disputes handled? Who should be contacted, and by when?
  7. What happens when an undisputed amount is late? Is there a reminder or pause process?

Plain-English payment terms example

Invoices are issued each Friday for approved hours worked Monday through Friday.
Payment is due in USD within 7 calendar days of the invoice date using the agreed
payment method. The client will raise any invoice dispute in writing within 3 business
days and identify the disputed line. Undisputed amounts remain payable by the due date.
Work may be paused after written notice if an undisputed invoice is overdue. Any late
fee applies only if stated in the signed agreement and permitted by applicable law.

This is an example, not a recommendation that every VA use seven-day terms. A larger company may have an established accounts-payable cycle, require a purchase order, or pay on a different schedule. The UK Small Business Commissioner recommends matching the invoice to the contract and including the due date, payment terms, bank details, and purchase order where applicable.

Choose a billing structure that fits the work

Structure Useful for Define carefully
Hourly, in arrears Ongoing work with changing volume Billable time, records, limit, and approval
Deposit plus balance Reserved time or a defined direct project Refundability, cancellation, and balance trigger
Milestones A larger project with reviewable stages Deliverable, amount, review window, and funding
Retainer Recurring service or reserved capacity Capacity, rollover, response time, and exit terms

Hourly, billed in arrears

This can suit ongoing work whose volume changes. Define what counts as billable, record time as you work, and agree on a weekly or monthly limit. Warn the client before exceeding it.

Deposit plus balance

A deposit can help when you reserve time or begin a defined direct project. State whether it is refundable, what happens on cancellation, and when the balance is due. Local law may control how deposits are described or treated.

Milestones

Each milestone needs a deliverable, amount, review window, and payment trigger. On a marketplace, use the platform’s official funding, submission, approval, and dispute flow.

Retainer

A retainer should reserve a stated amount of capacity or recurring service. Explain whether unused hours expire, roll over, or convert to another deliverable. Avoid “unlimited” support.

For a new direct client, a small paid trial or funded first milestone can limit exposure for both sides. It does not guarantee that no dispute will occur, so keep scope, approvals, and records clear.

Worked invoice examples

Hourly weekly invoice

Kai has an agreement for up to 15 hours each week at an illustrative $12 per hour. The approved time record shows 11.5 hours:

11.5 hours x $12.00 = $138.00 USD invoiced

The payment provider later deducts a receiving or conversion fee. Kai records the gross invoice, provider fee, and net deposit separately according to local bookkeeping and tax rules. Kai does not edit the invoice after payment simply to make its total equal the bank deposit.

Fixed project with milestones

Nora quotes an illustrative $300 for a defined contact-database cleanup:

Milestone 1: field map and 50-row sample approved      $100
Milestone 2: remaining agreed records processed        $150
Milestone 3: quality report and handoff                  $50
Total                                                   $300 USD

The agreement states the record limit, excluded research, duplicate rule, review window, and one correction pass. When the client requests 400 additional records, Nora sends a written change quote instead of hiding extra work in the final invoice.

Send the invoice with a clear note

Do not send a PDF with no context. Use a short message:

Subject: Invoice VA-2026-001 - due 17 July 2026

Hi [Name],

Attached is invoice VA-2026-001 for inbox and calendar support provided
from 1-7 July. The total is $180 USD and is due on 17 July using the
payment method in our agreement.

Please let me know if your billing team needs another reference or document.

Thanks,
[Name]

Check the recipient, attachment, invoice number, currency, total, due date, and payment details before pressing send. Then record the sent date and follow-up date in your invoice tracker.

Use a calm late-payment process

Before assuming the worst, check whether the invoice went to the right person, matches the purchase order, includes the required reference, and is genuinely overdue under the agreement. Confirm that the client received the deliverable and whether they raised a dispute.

Then follow a documented sequence:

  1. Before the due date, send a friendly reminder if that is your normal process.
  2. On or just after the due date, ask for confirmation and attach the invoice again.
  3. If it remains overdue, ask whether any line is disputed and request a payment date.
  4. At the threshold in the agreement, pause new work after written notice if permitted.
  5. If it remains unresolved, use the platform dispute process or seek local legal advice.

Friendly reminder template

Subject: Reminder - invoice VA-2026-001 due 17 July

Just a reminder that invoice VA-2026-001 for $180 USD is due on 17 July.
I have attached it again for convenience. Please let me know if anything is
missing for approval.

Overdue follow-up template

Subject: Overdue invoice VA-2026-001 - payment date request

Hi [Name],

Invoice VA-2026-001 for $180 USD was due on 17 July and remains unpaid in
my records. Please confirm whether any item is disputed and the date payment
will be sent. Under our agreement, I may pause new work after [date/notice].

I have attached the invoice and payment instructions again.

Thanks,
[Name]

Do not invent a late fee after the fact. Interest, collection costs, notice requirements, and enforceability vary. GOV.UK notes that businesses can agree their own terms and that late-payment rights exist under UK law, but those rules do not automatically apply to an international VA in another country.

Build the billing discussion into the Client Onboarding Checklist so the first invoice is expected rather than a surprise.

Final invoice checklist

  • Invoice number is unique and follows your sequence.
  • Your details and the client’s billing details are correct.
  • Service dates and descriptions match the agreement and records.
  • Hours, quantities, rates, tax, subtotal, and total recalculate correctly.
  • Currency is written explicitly.
  • Due date and payment instructions match the agreed terms.
  • Required contract, PO, project, or tax references appear.
  • The PDF contains no unnecessary sensitive information.
  • Changed payment details were verified through a trusted channel.
  • The sent copy and follow-up date are stored in your records.

FAQ

What should a VA invoice include?

Include a unique number, invoice and due dates, both parties’ required details, service period, clear work description, quantity or hours, rate, subtotal, applicable tax, total, explicit currency, payment instructions, and any required contract or purchase-order reference. Check your local legal and tax requirements too.

What payment terms should a beginner use?

There is no single best term. Choose a schedule both sides can follow and state the exact due date. Clarify whether the period uses calendar or business days and whether payment follows the invoice, delivery, approval, or a funded milestone.

Should I ask for a deposit?

A deposit or funded first milestone may reduce exposure on a new direct project. State whether the deposit is refundable and what cancellation means. Local law can affect how deposits are treated, and marketplaces have their own official funding rules.

Which currency should I put on the invoice?

Use the currency agreed with the client and supported by the payment route. Write it explicitly, such as USD, PHP, or GBP, rather than relying only on a currency symbol.

Can I charge a late fee?

Only when it was agreed in advance and is permitted by applicable law. Do not add one after the invoice becomes overdue. A clear reminder and pause process is often more useful than an unenforceable threat.

How do I record payment-provider fees?

Keep the gross invoice, provider fee, conversion cost, and net deposit as separate records under the bookkeeping and tax rules that apply to you. Do not edit the original invoice to make its total match the smaller amount that reached your account.
