Weekly Invoice Template for Contractors
A weekly invoice template for contractors who bill by the week: fields to include, a filled sample with hours and overtime math, week-ending dates and terms.
Billing every Friday keeps cash moving when you work for one client full-time or move between job sites. A weekly invoice template gives you a fixed layout for that routine: your details and the client's stay put, and each week you update the week-ending date, the hours or days worked, and the total. For contractors paid by the hour or day, it is the simplest way to stay paid up and avoid a month of unpaid work building up.
Below you will find the fields a weekly contractor invoice needs, a filled-in sample with overtime worked out, a step-by-step setup, and the mistakes that most often hold up weekly payments.
Who uses a weekly invoice template?
- Independent contractors on hourly or day rates, including IT contractors, engineers and site supervisors.
- Tradespeople working on longer jobs who bill labour weekly and materials as purchased.
- Staffing and labour suppliers who invoice clients for placed workers each week.
- Freelancers on short sprints, where weekly billing limits the risk of non-payment.
- Caregivers, tutors and nannies who bill families for regular weekly hours.
If your work is a steady fixed fee rather than hours, a monthly invoice template for ongoing services means less admin for both sides.
Fields every weekly invoice should include
The legal basics are the same as for any invoice. The UK government's checklist of what invoices must include is a good baseline: unique number, your details, the customer's details, a description, the supply date, the invoice date, amounts, VAT if any, and the total. For weekly billing, add:
- Week-ending date or the exact date range (for example, Mon 9 Nov to Sun 15 Nov 2026)
- Hours or days per day, or at least the weekly total by rate type
- Rate type: regular, overtime, weekend, call-out or day rate
- Site, project or job number if you work across more than one
- Timesheet reference or approver name
- Expenses such as mileage, parking or materials on separate lines
Weekly invoice sample with overtime
An electrical contractor bills a general contractor at $45 per hour, with time and a half ($67.50) for hours over 40 in a week, as agreed in the subcontract.
| Day | Date | Hours |
|---|---|---|
| Monday | 9 Nov 2026 | 9 |
| Tuesday | 10 Nov 2026 | 9 |
| Wednesday | 11 Nov 2026 | 10 |
| Thursday | 12 Nov 2026 | 9 |
| Friday | 13 Nov 2026 | 9 |
| Total | 46 |
| Description | Qty | Rate | Amount |
|---|---|---|---|
| Electrical labour, regular hours, week ending 15 Nov 2026, Job 3107 | 40 | $45.00 | $1,800.00 |
| Electrical labour, overtime at 1.5x (hours over 40) | 6 | $67.50 | $405.00 |
| Mileage, site to supplier (82 miles at $0.60, agreed rate) | 82 | $0.60 | $49.20 |
| Total due by 22 November 2026 | $2,254.20 | ||
The math: 46 hours minus 40 regular hours leaves 6 overtime hours. 40 x $45 = $1,800. 6 x ($45 x 1.5) = 6 x $67.50 = $405. Add $49.20 mileage for a total of $2,254.20. Invoice number EL-0147, terms Net 7.
How to create a weekly invoice, step by step
- Agree the week and the cut-off. Confirm which day the week ends and when invoices are due to the client's accounts team. Many clients run a weekly payment batch on a set day.
- Track time daily. Use a timesheet template that turns hours into invoices, filled in each day rather than from memory on Friday.
- Get the timesheet approved. If the client signs off hours, get approval before invoicing so the numbers match.
- Update the template. New invoice number, invoice date, week-ending date, hours by rate type and any expenses.
- Check the math. Multiply each line, add the subtotal, apply any tax, and compare the hours to the timesheet.
- Send it the same day each week with the timesheet attached, and note the due date in your records.

Payment terms that suit weekly billing
Weekly invoices need short terms. With Net 30 on a weekly cycle you could be waiting on four invoices at once. Net 7 payment terms line up neatly with a weekly rhythm: Friday's invoice is due the following Friday. Write the actual due date on the invoice as well as the term.
Setting the right rate before you bill
Weekly billing makes your rate very visible, so it pays to get it right. Include unpaid admin time, travel, tools and the weeks you do not work. Our freelance hourly rate calculator walks through that math. For US contractors, the contractor invoice template guide also covers W-9s and 1099 reporting.
Day rates, half days and minimum charges
Not every weekly contractor bills by the hour. Many trades and IT contractors use a day rate, and the template should reflect that. Show the number of days worked and the day rate, and spell out how partial days are handled. A common approach is to agree a standard day (for example 8 hours on site) and bill half days at 50 percent when you work 4 hours or less.
Example: a site supervisor on $380 per day works four full days and one half day in a week. The line reads "Site supervision, week ending 15 Nov 2026: 4.5 days at $380" and the total is 4.5 x $380 = $1,710. If your contract has a minimum call-out charge, for instance 2 hours for any visit, show it as its own line so the client understands why a short job costs more than the time on site.
Billing materials and expenses each week
Weekly invoices are a good place to recover costs while they are fresh. Keep materials and expenses separate from labour, and attach receipts. A short layout works well:
- Materials: "Cable, 2.5 mm twin and earth, 100 m (receipt 4471)" with the cost and any agreed markup shown.
- Mileage: miles driven and the agreed rate per mile.
- Parking and tolls: date and location, with receipts.
- Equipment hire: item, hire days and daily cost.
If you add a markup to materials, agree it in advance and state it, for example "Materials at cost plus 10%". Clients are far more likely to dispute a hidden markup than a disclosed one.
Numbering and tracking weekly invoices
At 52 invoices a year per client, a clear numbering scheme matters. Options that work well include a client code plus running number (ELX-0147), or year plus week number (2026-W46-01). The week-number approach makes it obvious when an invoice has been missed. Our invoice number generator can suggest a format. Keep a simple log with invoice number, week ending, amount, date sent and date paid, so you can see at a glance if a client's payment run has skipped one of your invoices.
Weekly invoice variations by trade
- Staffing suppliers: one section per worker, with name, role, hours by rate type and the charge rate, plus a total across all workers. Clients usually match this against approved timesheets, line by line.
- Construction subcontractors: labour by week, materials as purchased, and a job or plot reference on every line. Some contracts also require retention to be shown as a deduction.
- Freelance developers and designers: hours grouped by task or ticket rather than by day, which tells the client what the time was spent on.
- Caregivers and nannies: hours per day with any evening or weekend premium shown separately, and agreed expenses such as mileage for school runs.
- Cleaners and maintenance crews: visits listed by date and site, with a fixed price per visit, rather than hours.
Whatever the trade, the principle is the same. The client should be able to tick each line against something they already know, such as a timesheet, a ticket list or a visit log, without having to ask you.
What to do when a weekly invoice is late
Because invoices arrive every week, a single late payment can turn into three or four very quickly. Send a polite reminder the day after the due date, quoting the invoice number and week ending. If two invoices are overdue, raise it with your contact before starting the next week, and check whether your invoices are reaching the right accounts inbox. Many weekly payment problems turn out to be invoices sitting with the wrong person.
Common weekly invoicing mistakes
- Hours that do not match the timesheet. Even small differences stall approval.
- Missing week-ending date. An invoice dated 16 November does not tell the client which week it covers.
- Blending overtime into one line. A single line of 46 hours at a "blended" rate confuses approvers.
- Skipping a week and catching up later. Two weeks on one invoice breaks the client's matching process.
- Adding expenses without receipts or without the agreed mileage rate.

Frequently asked questions
What is a weekly invoice?
A weekly invoice is a bill covering one work week, usually sent on the last working day of that week or the first day of the next. Contractors, tradespeople, temporary staff, freelancers on hourly rates and agencies that place workers commonly bill weekly. It lists the dates or days worked, the hours or units, the rate and the total, and it has its own unique invoice number like any other invoice.
What does week ending mean on an invoice?
Week ending is the last day of the work week the invoice covers, for example "Week ending Sunday 15 November 2026". It is a short way to identify the period without listing every date. Agree with the client which day the week ends on (Friday, Saturday or Sunday are all common), and use the same convention on every invoice and timesheet so payroll and accounts can match them.
Should I attach a timesheet to a weekly invoice?
If you bill by the hour, yes. Many clients will only approve an hourly invoice when it matches a signed or approved timesheet. Attach it as a separate page or PDF, or summarise hours by day on the invoice itself. Make sure the totals on the timesheet and the invoice agree exactly, because a mismatch of even half an hour usually sends the invoice back to you.
What payment terms suit weekly invoicing?
Short terms work best because a new invoice follows a week later. Net 7 is common for weekly contractors, and some clients pay on receipt or on a fixed weekly payment run. Long terms such as Net 30 on weekly invoices mean you can have four or five unpaid invoices open at once, which ties up cash and makes tracking harder.
How do I show overtime on a weekly invoice?
Put regular and overtime hours on separate lines with their own rates. For example, 40 regular hours at $45 and 6 overtime hours at $67.50 (time and a half). Show the multiplier in the description so the client sees how the rate was calculated. Only bill overtime if your contract allows it, because independent contractors are not automatically entitled to overtime rates.
Can I bill several weeks on one invoice?
You can, but then it is effectively a biweekly or monthly invoice and the agreed billing cycle should say so. If your contract says weekly, stick to weekly. If a client asks you to combine weeks, list each week as a separate line or section with its own dates and hours so the invoice still matches the individual timesheets.
