Mobile phlebotomist
invoice template

Mobile phlebotomists invoice testing companies, private clinics, research organisations and individual patients for taking blood samples at home or at work. Below is a ready-made mobile phlebotomist invoice template, with worked example lines, the VAT and payment rules that apply, and the mistakes that most often delay payment.

What goes on a mobile phlebotomist invoice

List each visit or sample with the date, the patient or reference number used by the testing company (not medical details), travel beyond a set radius, and courier or postage of samples.

Line by line: Home visit, blood draw, 1 × £55.00 = £55.00; Additional patient at same address, 1 × £25.00 = £25.00; Sample courier to laboratory, 1 × £15.00 = £15.00. The subtotal is £95.00. The example assumes you are not VAT registered, so there is no VAT and the total due is £95.00. The figures are illustrative, not a price guide, so use your own rates.

The legal minimum is the same for every trade. GOV.UK says an invoice needs a unique number, your business name and address, the customer's name and address, a description of the work, the supply date and invoice date, the amount charged, VAT if you charge it, and the total due. This template lays each of those out for mobile phlebotomists; for the detail, read what a UK invoice must include.

Give each invoice the next number in a single sequence and never reuse one. A cancelled invoice keeps its number and is cancelled with a credit note. If you want a format that stays tidy for years, try the invoice number generator.

How mobile phlebotomists price their work

Per visit, with a reduced fee for additional patients at the same address and supplements for travel and urgent samples.

Keep the pricing visible. Each line should show the quantity, the unit and the rate, so the customer can match it to the quote. To set rates that cover your costs and your tax, try the day rate calculator; for materials and stock you resell, the profit margin calculator shows the margin you really make.

Agree this before you start

Agree with testing companies the fee per draw, what happens when a draw fails or a patient is out, travel, and how samples reach the laboratory. Keep medical details off the invoice; use their reference number.

When to send a mobile phlebotomist invoice

Weekly or monthly for testing companies, per visit for private patients.

An invoice sent on the day tends to be paid on time; one sent weeks later tends to be paid weeks later. Email it as a PDF and keep a copy. The invoice due date calculator shows exactly when payment falls due under your terms.

VAT on mobile phlebotomist invoices

Blood taking counts as exempt medical care when you are a registered health professional, such as an NMC-registered nurse, or work under the direct supervision of one. An unregistered phlebotomist working independently may not qualify, which matters only if taxable income reaches £90,000.

If you are on a qualifying statutory register, the medical care you provide is VAT exempt. That covers treatment; it does not automatically cover everything you sell. Medico-legal reports, non-medical wellbeing sessions and retail products can be standard-rated, so if a mix of supplies ever takes you over £90,000 of taxable turnover, registration becomes a question worth checking.

Registration is compulsory once taxable turnover in the last 12 months passes £90,000, or when you expect to pass it within the next 30 days. Check your position with the VAT registration checker; until then, see invoicing without a VAT number.

Who mobile phlebotomists invoice

Insurers, employers and solicitors paying for treatment each have their own rules: an authorisation number, treatment dates and your professional registration on the invoice are the usual minimum. Patients paying for themselves often reclaim part of the cost from a health cash plan, so list each session with its date and price.

Testing companies usually self-bill or require invoices through their portal, with their booking reference for each draw.

Recharging costs and expenses

When you agreed to pass on costs, list them separately: mileage at an agreed rate, parking, materials or anything bought for the customer. The recharge is income and the cost is an expense, both in full. Registered businesses charge VAT on the recharge as part of their service; a true disbursement, paid as the customer's agent, is the narrow exception. Use the mileage calculator to value your business miles.

Invoices patients can claim back

An invoice for treatment does two jobs: it asks for payment and it lets the patient reclaim from a health cash plan or insurer. For the second job it needs your registration body and number, the treatment date and type, the patient's name and the amount paid. Insurer-funded courses need the authorisation number on every invoice and must stay within the sessions authorised. Clinical detail belongs in your notes, not on the invoice.

Deposits, stages and cancellations

Not usual.

Paid-in-advance treatment packages are common; invoice the package once, list the sessions it covers, and track the ones used. A missed-appointment fee is fair when patients were told about it at booking.

Payment terms for mobile phlebotomists

Testing companies typically pay 30 days after month end.

Between businesses, the default when nothing is agreed is 30 days from receipt of the invoice or the work, whichever comes later, and agreed terms should not normally exceed 60 days. Late business payers owe statutory interest at 8% above Bank Rate plus fixed compensation per invoice; the late payment interest calculator does the sums. Private individuals are not covered by that Act, so agree your terms with them in writing before the work starts.

Getting paid faster

Put everything the customer needs to pay on the invoice: your bank name, account name, sort code and account number, and the reference to use, normally the invoice number. Give a due date, not just "on receipt". Then follow a routine: a reminder the day after the due date, another a week later, and a firmer letter after two weeks. Most late payment is disorganisation, not refusal, and a routine fixes it. Invoice payment terms compares the common options, and the due date calculator turns them into a date.

If a customer disputes the invoice

When a customer queries an invoice, reply quickly and in writing, quote the quote or agreement, and ask them to pay the part they accept while you resolve the rest. A credit note can settle a partial dispute cleanly. Unpaid after reminders? Send a letter before action with a final date; in England and Wales, claims up to £10,000 can then go to the small claims track. Invoice disputes and small claims for an unpaid invoice have the detail.

Common mobile phlebotomist invoicing mistakes

• Medical details on the invoice. Use the testing company's booking reference only; never test names or results.
• Failed visits unpaid. Agree a fee for visits where the patient is not in or a draw fails.
• Assuming the VAT exemption. It depends on being a registered health professional or directly supervised by one.
• Leaving out the due date. "Payment due within 14 days" or a date on the invoice gives you something to chase against. Without one, business customers default to 30 days.
• Losing track of what is unpaid. Chase on the day after the due date, not a month later; the guide to chasing an unpaid invoice has the wording.

Checklist before you send it

A quick check before sending saves a chase later:

• The invoice number is the next in your sequence and has never been used.
• The customer's name and address are right, with their purchase order or reference if they use one.
• Each line shows what was done, the quantity, the unit and the rate.
• The subtotal and total add up, and VAT appears only if you are VAT registered.
• The invoice date, a due date and your bank details are on it.
• A copy is saved with your records before you press send.

Keep a copy of every invoice

Your invoices are the evidence behind the income on your tax return, so keep a copy of every one.

Check your start date with the MTD requirement checker.
