The Extras That Never Get Billed: How to Stop Working for Free
Every contractor knows the line. The client walks onto the site, looks at the open wall and says: "While you're here, could you also…" One more outlet, a relocated door, a strip of flooring. Nothing dramatic taken one at a time. But added up over a job, these little tasks often represent thousands of dollars — and a good chunk of it will never be invoiced. Not because the client refuses to pay: because the extra was never documented, never approved, never turned into an invoice. Here's how to close that leak.
1. Why extras don't get billed
The problem is rarely the client. It's the process — or rather, the lack of one:
- The extra isn't written down anywhere. The deal was made standing in the dust, between two saw cuts. Three weeks later, nobody remembers the agreed price — or whether there even was one.
- Fear of the conversation. Billing an extra means telling the client the invoice is going up. Many contractors prefer to "absorb it" rather than have the discussion — telling themselves it protects the relationship. In reality, it teaches the client that everything is free.
- The end-of-job dump. Extras pile up unbilled, then land all at once on the final invoice. The client falls off their chair, disputes everything, and the negotiation happens at the worst possible moment: the work is done and your leverage is zero.
All three causes have the same cure: a systematic process, applied to every extra, even the small ones.
2. First, know what counts as an extra
An extra is only defensible if the contract's scope is clear. If your quote says "bathroom renovation," everything becomes debatable. If it details the work line by line — demolition, plumbing, ceramic supplied and installed, two coats of paint — then anything not on it is an extra, period.
That's one more reason to take your quotes seriously: the line between "included" and "extra" gets drawn before signing, not during the job. (We wrote a complete guide to quoting on exactly this.)
Worth knowing too: in Quebec, under a fixed-price contract, the Civil Code provides that the contractor cannot claim an increase over the agreed price for the work covered by the contract. Additional work needs its own separate agreement — and that's exactly what a documented extra creates. A verbal agreement is valid in principle, but nearly impossible to prove once things get tense. Writing protects both sides.
3. The golden rule: approved before, not billed after
The rule that solves 90% of extra-related problems fits in one sentence: no additional work starts before the client has approved a description and a price.
Concretely, when the "while you're here" moment arrives:
- Describe the work in a few precise lines: what, where, with which materials.
- Put a number on it. A firm price if you can, an estimate with a range if you can't — but a number. "We'll settle that at the end" is the most expensive sentence in construction.
- Get written approval before doing the work. An approval document sent to the client, which they accept from their phone in thirty seconds. Not next week: now, while the need is alive.
What if the client approves verbally on site? It happens all the time, and it's not a disaster — as long as you document it immediately: note who approved and when, then confirm in writing the same day ("As discussed this morning, we're adding X for $Y plus tax"). An uncontested written confirmation beats a memory every time.
One reflex that helps: photos. A photo of the discovered problem (the rotten joist, the out-of-code pipe) attached to the extra request turns a "surprise invoice" into plain evidence. The client is no longer paying an abstract amount — they're paying to fix what they saw.
4. Invoice the extra like a contract: fast and detailed
An extra that was approved but invoiced three months later in a lump sum is still a disputed extra. The same rules as the main contract apply:
- Invoice without delay — ideally on the current milestone's invoice, or on a dedicated invoice as soon as the extra is done. The fresher the work is in the client's memory, the less it gets argued.
- Itemize every extra on the invoice: description, reference to the approval, amount, GST and QST. An extra that shows up as a clear, already-approved line triggers no conversation. A lump "additional work: $2,400" always triggers one.
- Keep a running tally. At any point in the job, you should know how many extras are approved, completed, invoiced — and which ones are sitting idle. The approved-but-never-invoiced extras are often the most expensive kind: the work is done, the money is simply forgotten.
5. The real cost of doing nothing
Run the numbers for your own business. One "absorbed" extra of $250 per week is $13,000 a year — taken straight out of your margin, not your revenue. For many independent contractors, that's the difference between a good year and a bad one, lost thirty bucks at a time.
And the reverse effect is just as real: the contractor who documents extras properly comes across as more professional, not less. The client always knows where things stand, the final invoice surprises no one, and the money conversation happens when it's easy — before the work — instead of when it's painful.
Bottom line: a reflex, not a confrontation
Managing extras isn't about learning to fight with your clients. It's about installing a reflex: request → priced description → written approval → execution → itemized invoice. Each step takes minutes. The only step that never forgives being skipped is the third one.
At Vantage, this process is built into project tracking: you create the extra with its detailed line items, the client approves it online from their phone through a secure link (or you log a verbal approval in two clicks), then you invoice it with GST and QST calculated automatically. The dashboard shows you at all times which extras are approved but not yet invoiced — the money that's sleeping. Try it free — 30 days, every feature, no credit card.
