TapeAndFloat.comUnbilled change order calculator for drywall contractors
An unbilled change order is extra work your crew did that never made it onto an invoice. This free calculator turns 4 of your own numbers (jobs a month, change orders per job, average change order and percent unbilled) into a monthly and yearly cost.
How much extra work does your crew do that never gets billed? Put in your own numbers and see what unbilled change orders cost you per month, per year and per job. Free, no sign-up, nothing you type leaves your browser.
The math: jobs per month × 12 × change orders per job × unbilled share = unbilled change orders per year, times the average value = dollars per year. Your numbers only; no averages are assumed.
Why extras slip through
- Approved by text or on site. The super says "go ahead" and nobody writes it up.
- Signed but never invoiced. The paper is in the truck, not in the office.
- Billed late. By the time it's invoiced the GC disputes it, or the lien window is closing.
How to get a GC to sign before the work starts: Drywall change orders a GC will actually sign. Track every extra in the free office tracker (flags unsigned and unbilled change orders), and run the weekly office checklist every Friday. If an extra goes unpaid in Texas, check your lien deadlines.
Frequently asked questions
What counts as an unbilled change order? Any extra work your crew did beyond the original scope (added walls, patching after other trades, upgraded finish level, extra trips) that was agreed to by text, phone or on site but never got written up, signed or added to an invoice.
Where do I find my own numbers? Count change orders on your last 10 finished jobs from texts, emails and daily notes, then check how many show up on an invoice. The share that never made it onto an invoice is your unbilled percentage.
Is this an industry average? No. The calculator uses only the numbers you type in. Nothing is pre-filled and nothing you enter leaves your browser.
How do I stop change orders from going unbilled? Write every extra down the same day, get a signature or a written OK before or right after the work, and check each invoice against the change order log before it goes out. The free office tracker and weekly checklist below help with both.
