T&M Tickets Done Right: Get Paid for Every Extra Hour
TL;DR — 30 seconds
T&M tickets done right — authorization before extra work starts, daily capture with photos and signatures, agreed rate sheets, and invoices out the door same week. See it on your plans →
Time and materials work is the best money on a job — and the easiest to lose. When an owner directs extra work outside the contract scope, T&M tickets are your invoice’s foundation: crew hours, equipment hours, and materials used, documented well enough to survive review. Yet across the industry, tickets die in truck cabs, sit unsigned for weeks, and get rejected over missing authorizations. The contractors who actually collect T&M revenue follow a short list of disciplines, none of them complicated.
Authorization First, Always
The single most expensive T&M mistake is starting extra work on a phone conversation. Before the crew touches it:
- Get written authorization — email counts; a signed work directive is better
- Confirm the work is genuinely outside contract scope (or that both sides agree to handle it T&M)
- Agree on the cap: estimated hours or not-to-exceed amount, so nobody gets surprised
- Note who authorized it, when, and what exactly was directed
Without authorization, you’re not billing — you’re hoping. Owner’s reps routinely refuse tickets for work they never directed in writing, and a verbal “go ahead” from someone without authority is worth nothing at dispute time.
Capture Daily, With Evidence
A ticket written three days later from memory will be wrong, and wrongness costs either recovery or credibility. The daily habit:
- Labor: each worker, classification, hours by day — pulled straight from time tracking rather than retyped
- Equipment: unit numbers, hours operated versus standby (contracts often pay standby at reduced rates)
- Materials: quantities, sources, delivery tickets attached
- Photos timestamped at the site showing the condition before, during, and after (photo documentation standards)
- Signatures: foreman on every ticket; owner’s rep where practical
Signatures deserve special attention. An owner’s representative who signs the daily ticket has acknowledged the work happened — that acknowledgment is nearly impossible to unwind later, which is exactly why disciplined reps sign reluctantly and sloppy contractors chase them. Make signing easy: present the ticket complete, with photos, at end of shift.
Rate Sheets Agreed Upfront
T&M invoices fail over rates more often than quantities. Before the project starts — or before any T&M directive if the contract is silent:
- Lock labor rate classifications matching your certified or prevailing payroll structure, including workers’ comp, burden, and markups per the contract
- Fix equipment rates — published rental-rate schedules or your own schedule appended to the agreement
- State markup percentages on materials and sub-rentals explicitly
Every one of these negotiated before work begins is a line item nobody argues about after. Rates discovered mid-job become negotiation sessions, and negotiation sessions have a way of settling 20% below invoiced amounts.
Turn Tickets Into Invoices Same Week
T&M revenue decays fast. Every week between work performed and invoice submitted:
- Memories fade and supporting details go stale
- The owner’s budget for the period closes
- Your leverage drops because the work recedes into history
Best practice among contractors who recover nearly all their T&M: batch approved tickets into invoices the same week the work closes out, referencing authorizations, signed tickets, and photo evidence together. Aging reports should flag unconverted tickets in red. A ticket older than 30 days without an invoice behind it should bother somebody enough to fix the process.
| Ticket element | Why it matters |
|---|---|
| Written authorization reference | Proves the work was directed |
| Date, location, work description | Ties effort to a specific event |
| Named labor + classifications | Survives payroll audits |
| Equipment hours w/ unit numbers | Prevents blanket “1 week” claims |
| Materials + delivery docs | Substantiates pass-through cost |
| Photos | Ends “did this even happen” debates |
| Foreman + owner signatures | Converts records into admissions |
Extra work and change orders are two halves of the same pipeline — tickets document cost while the CO process converts them into contract value.
