How to Invoice as a Virtual Assistant: Rates, Terms and Templates

TL;DR: Show hours by task category (inbox, scheduling, CRM, research) on every invoice, track package or retainer hours used versus remaining, and bill biweekly or monthly with a brief activity summary so remote clients see exactly what they are paying for.

Virtual assistants sell reliable execution—inbox triage, scheduling, CRM updates, light bookkeeping prep, or industry-specific admin. Invoices should show how time or packages were used so clients trust remote work they cannot see.

Whether you bill hourly, weekly caps, or monthly bundles, clarity beats a single mystery total.

Because clients rarely watch you work, invoices are proof of professional judgment—how you allocated time across inboxes, tools, and follow-ups. A readable breakdown builds trust faster than a single lump sum ever will.

Typical rates

Hourly remains common for general VAs; packaged hours (e.g. 20/month) improve predictability for you and the client. Specialized VAs (real estate, e-commerce ops) can charge more than generalist rates. The IRS gig economy overview reminds independent contractors to track income and expenses—useful context when clients ask why your business name and tax details appear on invoices.

Rush or after-hours work deserves a surcharge defined in advance and shown as its own line when used.

Tooling you provide (scheduling software, password managers) can be a small monthly line or folded into rate—either way, be explicit so clients do not assume tools are free forever.

Sample invoice line items

When to send the invoice

For monthly packages, invoice on the first business day of each month (prepaid). Attach a brief summary of the prior month's task breakdown so the client can verify how hours were allocated.

On hourly billing without a package, invoice biweekly or weekly, depending on volume. Frequent invoicing keeps amounts manageable and reduces payment friction.

For project-based VA work (event planning support, database migration, one-time research projects), invoice 50% at kick-off and 50% on completion, or 100% on delivery for smaller projects under $500.

Payment terms

Biweekly or monthly billing aligned to payroll cycles wins approvals. Due on receipt or Net 7 for new clients; Net 15 once trust is built. For retainer packages, bill at the start of the period; unused hours may roll only if your agreement says so—state the rule on each invoice.

Holiday or PTO weeks should not surprise clients—note non-working dates in the invoice memo if you prorate.

International transfers may need IBAN/SWIFT or Wise details on the PDF—repeat them monthly if your client’s AP team rotates.

What to include

Period covered, tasks or categories (calendar, travel, data entry), hours per category or package name, reimbursable expenses with receipts referenced, tax if applicable, total, due date. Read what to include on an invoice for full checklists.

Meeting and email time counts—say so in the agreement and summarize on the bill.

Common mistakes

Block billing with no breakdown—clients assume padding. Unlimited tasks for a flat fee without boundaries. No overage rate when packages exceed—define hourly overage upfront. Chasing payment without a documented policy—late fees need prior agreement.

Mixing personal errands for executives without clarity on what is billable—put examples in your contract.

Waiting until month-end to log time—you forget context; log daily and invoice from clean notes.

FAQ

Should I track time by task category even if I bill a flat monthly rate? Yes. Showing a task-category breakdown on the invoice builds trust with remote clients who cannot observe your work directly. Categories like "inbox management -- 6 hrs," "scheduling -- 4 hrs," and "CRM updates -- 3 hrs" demonstrate where the hours went and help the client assess whether the package size is right.

How do I handle overage hours when the client exceeds their package? Define an overage rate in your contract (typically 10-20% above the package per-hour rate). When hours exceed the package, add an "overage hours" line item with the rate and a brief description of the work. Notify the client before you exceed the package limit so there are no surprises on the invoice.

What if the client asks me to use their tools and accounts -- should I bill for setup time? Yes, if onboarding to new tools takes more than a few minutes. Bill initial setup and tool-learning time as a one-time onboarding line item on the first invoice. State the onboarding scope in your proposal so the client expects the charge. Ongoing tool usage is part of your regular hours.
