Free Invoice Template for Virtual Assistants
Invoice template for virtual assistants. Bill hourly or on retainer, with support for task-based pricing, software subscription pass-throughs, and overtime tracking.
A virtual assistant invoices the retainer of prepaid hours in advance — the client is buying reserved availability, not completed output — then bills overage hours and pass-through software subscriptions in arrears. Show hours purchased against hours used, grouped by category like inbox and calendar management or project work, plus the rollover treatment for unused hours, the published overage rate, and your coverage window and time zone. Onboarding and systems setup are billed separately.
Virtual assistance is billed against time that the client cannot see, and that single fact shapes everything about the invoice. There is no deliverable to point at at the end of the month, just an inbox that stayed under control and a calendar that did not collapse. A VA invoice therefore has to do double duty as a record of work, summarising where the hours went in categories the client recognizes rather than in an undifferentiated total.
Most established VAs work on retainers of prepaid hours, which introduces the question every retainer eventually faces: what happens to unused time. A rollover policy that carries hours forward indefinitely turns into a large unfunded liability, while a strict use-it-or-lose-it rule irritates clients in quiet months. Whichever line you take, it belongs on the invoice, showing hours purchased, hours used, and the balance treatment applied.
Working across time zones adds a layer that domestic services never deal with. A client in one hemisphere and an assistant in another need explicit agreement on coverage windows, response expectations, and what counts as urgent. When a client starts expecting replies outside those windows, the cleanest response is a priced line item for extended coverage rather than a quiet erosion of your working day.
Common Line Items on a Virtual Assistant Invoice
Retainer hour block
A prepaid monthly allowance of hours, the standard structure for ongoing support.
Overage hours
Time worked beyond the retainer, billed at a stated per-hour rate agreed in advance.
Inbox and calendar management
The recurring administrative core, worth categorizing so the client sees where routine hours go.
Project or one-off task work
Discrete pieces such as a CRM cleanup or event research, priced per project rather than drawn from the retainer.
Specialised task rate
Bookkeeping, design, or technical work priced above general admin because the skill differs.
Software and subscription costs
Tools bought on the client's behalf, passed through at cost and clearly separated from your fee.
Extended or out-of-hours coverage
Availability outside the agreed time zone window, priced rather than absorbed.
Onboarding and systems setup
The initial period spent documenting processes and gaining access to the client's tools.
What to Include on Your Invoice
| Field | Why It Matters |
|---|---|
| Retainer hours purchased versus hours used | The retainer is the product, so the invoice must show consumption against the allowance every cycle. |
| Hours grouped by task category | A single total invites suspicion, while a breakdown by inbox, scheduling, and projects reads as accountability. |
| Rollover treatment for unused hours | Restating the policy each month prevents a client from claiming a year of accumulated credit. |
| Overage rate and authorisation note | Extra hours should be visibly tied to a rate and, ideally, to an approval the client gave. |
| Coverage window and time zone | It defines when you are contactable and makes out-of-hours charges defensible. |
| Pass-through subscriptions listed separately | Tools bought on the client's card versus yours affects both reimbursement and the apparent size of your fee. |
How Virtual Assistants Set Their Rates
Retainers of prepaid hours are the standard, because they give the client guaranteed availability and give the assistant predictable income. Blocks are typically sold monthly, with larger blocks carrying a lower effective hourly cost in exchange for volume and commitment. Pure hourly billing persists for ad hoc and short-term clients but tends to be priced above the retainer equivalent, since irregular work is harder to schedule around. Some assistants operate a tiered rate card, charging general administration at one level and specialized work such as bookkeeping, copywriting, or technical setup at another, which lets one relationship cover a wide brief without underpricing the harder tasks. Project-based pricing appears for defined pieces with clear boundaries. Overage rates should always be published alongside the retainer so extra work never requires renegotiation mid-month.
Payment Terms for Virtual Assistants
Retainers are invoiced in advance, before the month of work begins, since the client is buying reserved availability rather than completed output. Overage hours and pass-through expenses are then billed in arrears on the following cycle, usually on short net terms. New engagements often start with the first retainer plus an onboarding fee covering the unpaid ramp-up spent learning systems and documenting processes. Rollover policies vary, but a common approach allows a limited number of unused hours to carry into the next month only, preventing an open-ended balance. Cancellation typically requires notice of around thirty days, with the notice period billable because the assistant has held capacity. Where the VA purchases software on the client's behalf, most prefer the client to hold the payment method rather than carrying subscriptions personally.
Invoicing Tips for Virtual Assistants
- ✓For hourly billing, include a detailed time log showing date, task description, and hours for each entry — clients need to verify how their hours were spent.
- ✓For retainer billing, list the included hours, hours used, and remaining balance so clients can manage their allocation throughout the month.
- ✓Bill software subscriptions (project management tools, scheduling apps, CRM) as separate pass-through line items with the actual subscription cost — do not absorb these into your rate.
- ✓Track and invoice overtime hours (beyond the retainer or agreed weekly hours) at a premium rate (1.25-1.5x) and get pre-approval before exceeding the limit.
Frequently Asked Questions
Should virtual assistants bill hourly or on retainer?
Retainers provide predictable income and are preferred for ongoing clients — offer 10, 20, or 40-hour monthly packages. Hourly billing works for occasional or project-based clients. Many VAs offer a slight discount (5-10%) on retainer hours vs. ad hoc hourly rates.
How do virtual assistants track and invoice time?
Use a time-tracking tool (Toggl, Clockify, Harvest) and attach a detailed time report to each invoice. List entries by date, task category, and duration. Round to the nearest 15-minute increment and show the running total.
Can virtual assistants charge for software costs?
Yes. If you use paid tools on behalf of a client (scheduling software, design tools, CRM), invoice the subscription cost as a pass-through expense. List the tool name, billing period, and cost. Get client approval before subscribing to any new tools.
How do virtual assistants handle scope creep on invoices?
Track hours by task category. When a client regularly requests work outside the original scope, document it on the invoice and propose a scope adjustment. Bill out-of-scope tasks at your standard hourly rate as a separate line item.
