T&M priced correctly, every entry
Set a project, task, or subtask to Time & Materials and each hour computes as hours × customer rate automatically.
T&M is one of 3 native billing types (T&M, Fixed Price, OVH) with per-level inheritance.
Time & Materials (T&M) tracking
Track time-and-materials work and what it's worth
On time-and-materials work, every hour that doesn't get logged is revenue you already earned and threw away. Timix.AI captures T&M hours fast, prices them at the customer rate, caps the engagement so the client's never surprised, and shows the margin behind the billables — then turns approved hours into a commercial invoice (Professional+) or exports them for the tool you bill from.

Illustrative entries
01 The problem
On T&M, unlogged is unpaid
Time-and-materials only works if the time gets recorded — all of it, defensibly, before it's billed. The losses are quiet, and they're pure margin.
Under-recorded hours are lost revenue
The 20-minute call, the after-hours fix — the hours people don't bother logging are exactly the billable ones, and on T&M they're gone for good.
There's no defensible, approved record to bill from
Billing T&M means standing behind the hours. Reconstructed-from-memory timesheets aren't a record a client will accept without a fight.
A T&M engagement runs past where the client expected
Without a not-to-exceed cap that warns, an open-ended engagement quietly blows past the number the client had in their head — and that's a hard conversation at billing time.
02 How Timix.AI fits
Hours × rate, capped, approved, exportable
T&M is a first-class billing type here, not a workaround — priced correctly per entry, capped where you need it, and approved before it's exported.
The not-to-exceed, as a cap that warns
An hour-cap budget with soft and hard limits and alert thresholds is your NTE: warn the team before it's hit, block at the ceiling.
T&M hour-cap budgets with soft/hard limits + alert thresholds.
Approved hours, billing-ready
The Draft → Submitted → Approved workflow gives you a defensible record, with reject-and-reason and an approval history when an entry's disputed; Unbilled Time and Customer Billing reports export to PDF/CSV — or become a commercial invoice you send (Professional+).
Approval workflow (reject-with-reason + history); built-in reports incl. Unbilled Time & Customer Billing → PDF/CSV.
Margin, not just billables
Cost rate alongside customer rate means T&M shows profit, so a fully-billed engagement that's barely profitable can't hide.
Dual rates → revenue/cost/profit/margin; effective-dated cost rates.
3 billing types, with T&M first-class — plus Fixed Price and OVH
2 rates on every hour — customer rate and cost rate
Many reports, including Unbilled Time, exportable

04 FAQ
T&M tracking, asked and answered
Does “Time & Materials” here include tracking materials or expenses?
No — Timix.AI costs the time, not the materials. There's no expense, materials, receipt, or mileage tracking; T&M means hours × your customer rate. Materials and expenses live in your accounting tool.
Can I cap a T&M engagement so it doesn't run away?
Yes — set an hour-cap budget as your not-to-exceed, with a soft limit that warns, alert thresholds at the percentage you choose, and a hard limit that blocks further entries.
Does it generate the T&M invoice?
Yes — on Professional and up, Timix.AI turns approved T&M hours into a commercial invoice (line items at your bill rates, tax, branded PDF). You also get defensible Unbilled Time / Customer Billing exports (PDF/CSV) to bill from your accounting tool where local e-invoicing rules require it.
Can several people log to the same T&M engagement?
Yes — a whole team can log against one engagement, and each entry passes through Draft → Submitted → Approved (with reject-and-reason) so the record's clean before it's exported.
