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.

Industry rate benchmarks (2026)

Virtual assistant rates depend on specialization and client tier. Working ranges from VA Networking + IVAA 2025 compensation data:

Premium factors: industry specialization (real estate, legal, medical) adds 25-40%, demonstrated proficiency in specific software stacks (HubSpot, Zapier, advanced Notion) adds 20-30%, executive support experience commands top quartile.

Step-by-step: Sending your first VA invoice

Step 1: Bill in monthly retainers, not per-task

VA work is too granular for hourly billing. Standard: monthly retainer for X hours/month, paid upfront. "20 hours/month at $40/hr = $800/month, billed first of month." Caps protect both sides — client knows the budget, you know your scope.

Step 2: Track hours rigorously and report monthly

Even on a flat retainer, log every task with time. End-of-month: send a summary with the invoice. "20 hours used of 20 retained. Top tasks: inbox triage (8h), CRM updates (5h), travel booking (4h), misc (3h)." Transparency makes retainer renewal easier.

Step 3: Define overage handling on every invoice

What happens if a month runs over? Three options: (1) overflow billed hourly at $X/hr at month-end, (2) rolled to next month's retainer (extra hours need pre-approval), (3) hard cap with work paused at retainer limit. State the policy on the invoice footer.

Step 4: Bill for tools and subscriptions separately

If you're managing the client's HubSpot, ConvertKit, Zapier, etc., either they pay vendors directly or you pass through with itemization: "Reimbursable software — Zapier ($50) + Calendly ($14) = $64". Don't absorb tool costs into your hourly rate; it eats your margin.

Step 5: Set up auto-recurring invoices for retainer clients

Stripe and most invoicing tools support recurring invoices. Set up once, runs monthly. Client receives the invoice predictably; you're not chasing payment manually each month. Invoice on day 1 of month, due day 5, retainer hours start day 5.

Common VA billing scenarios

Solopreneur who hires you for 10 hrs/week: $40/hr × 40 hrs/month = $1,600/month retainer. Billed first of month, 20% discount if paid quarterly upfront. Auto-charged via Stripe. End-of-month report attached to invoice with hours used.

Agency hires you for project-based work: Specific project (e.g., conference logistics) for 3 months at $3,000/month. Define scope on invoice — "Conference X support: vendor coordination, registration management, post-event reporting." After 3 months, transition to retainer or part ways cleanly.

Multiple part-time clients: 4 clients at 10 hrs/month each = 40 billable hrs/month. Bill each separately with their own retainer. Don't pool hours across clients (they each booked you for their reserved time).

Client wants to "try a few hours" before committing: Charge full hourly rate for trial; don't discount. Trials at full rate filter for serious clients. Trial-to-retainer conversion target is 50-70% in good VA practices.

Frequently Asked Questions

Should I charge sales tax on VA services?

VA services are generally exempt from sales tax in most US states (services aren't taxed). Exceptions: a few states tax certain administrative services. Check your state. International clients (UK, EU) generally don't pay your tax — they self-assess via reverse charge for B2B.

How do I handle clients who go silent for weeks?

Retainer continues during silent periods — they paid for the slot. State on invoice: "Retainer covers reserved availability. Unused hours expire at month end." Some VAs offer 1-month rollover as goodwill. Don't allow indefinite carryover; it kills your scheduling capacity.

What's the right ratio of clients?

Most full-time VAs work with 3-5 retainer clients. More than 6 = administrative overhead eats your margin. Fewer than 3 = concentration risk. New VAs often start with 6-8 small clients and consolidate to fewer/bigger over 18-24 months.

Can I bill a client for screening tasks (researching options before they decide)?

Yes — research is billable work. Document scope upfront: "Vendor research — 3 hours" then bill regardless of whether the client picks an option. If they want re-research after decision, that's a new task, billed separately.

A client wants to share my services with their colleague. How do I bill that?

Each person is a separate retainer. Don't split one retainer between two principals — schedules clash, scope expands, your hours evaporate. State on every invoice: "Retainer covers support to [Client Name] only. Additional principals require separate engagement."
