The paperwork side of running trade work: what to put on a document, how to price it, and how to get paid for it without chasing.

• Change orders that actually get paid

  Most unpaid extra work was agreed verbally, mid-job, by someone with their hands full. Here is the process that prevents it.

• E-signatures on estimates: what they do and don't do

  A typed or drawn signature on an estimate is normal practice for accepting a proposal. Here is what it is good for, and where it stops.

• Estimate, quote or invoice — which one to send

  The three documents do different jobs, and sending the wrong one is how contractors end up bound to a price they meant as a ballpark.

• Free invoice generators that don't make you sign up

  Five free invoicing tools compared on the thing that actually differs: whether you need an account, whether invoices are capped, and what happens to your data. Prices checked October 2026.

• How to collect a deposit without losing the job

  Deposits stop you financing someone else's project. Asking for one is a matter of what you tie it to and when you ask.

• How to get paid faster

  Most late payments are not customers refusing to pay. They are invoices sent late, missing a due date, or hard to act on.

• How to price a job so the work is actually worth doing

  Your hourly rate is not what you pay yourself. Here is how to build a number that covers overhead and leaves a margin, without guessing.

• Quoting a panel upgrade when the utility controls your schedule

  A service upgrade is three jobs: the load calculation, the work itself, and coordinating a utility and an inspector you do not control. How to price and sequence all three.

• Quoting a roof replacement when the deck is a guess

  Squares and pitch are the easy part. What decides whether a roof is profitable is the decking allowance, the layer count and who is really paying — the homeowner or their insurer.

• Quoting a water heater replacement without eating the difference

  The variables that decide whether a heater swap is a two-hour job or a two-day one — venting, code upgrades, access and permit — and how to put each on the quote before you find it.

• Quoting an AC changeout when you have not been in the attic

  Tonnage, refrigerant, ductwork and panel capacity decide an HVAC changeout price — and three of the four are hidden at the walkthrough. How to price what you can see and name what you cannot.

• Scope and exclusions: the paragraph that prevents the argument

  Nearly every dispute about trade work is a disagreement about what was included. Exclusions are cheaper than lawyers.

• What actually belongs on a contractor invoice

  The fields that get an invoice paid, the ones some states require, and the ones that quietly cost you money when they're missing.
