Quote vs estimate: a worked example from price range to fixed scope
Compare a complete estimate with the later quote for the same job, calculate an extra-work request and avoid changing the agreed scope silently.
Choose the document by what you know about the job. An estimate explains an informed price range and its uncertainties; a quote sets out a specific offer. Follow fictional catalog-import project C-041 from an unknown file to an agreed scope. All prices below are illustrative USD amounts, with tax excluded from the exercise.
Before inspecting the file: explain the range
North Studio has not yet inspected all of a retailer's product data. It budgets eight to twelve hours at USD 65, plus USD 150 for field mapping. The lower figure is 8 × 65 + 150 = USD 670; the upper figure is 12 × 65 + 150 = USD 930. Neither figure is a promise that every possible cleanup task is included.
List the unknowns that actually affect the work: duplicate rows, missing image links and inconsistent size labels. A large unexplained range gives the buyer less useful information than a smaller range tied to explicit assumptions.
ESTIMATE E-041 — catalog import Expected price: USD 670–930, excluding tax in this example. Basis: 8–12 hours at USD 65 plus USD 150 for field mapping. Assumptions: one supplied CSV, one store and up to 200 products. Not included: writing missing product descriptions or producing images. Next step: inspect a representative sample, confirm exceptions and agree the final scope before work starts.
After inspection: write the defined offer
The sample establishes that the agreed cleanup fits a ten-hour planning allowance. The studio offers a fixed USD 800 for the defined deliverable. Its internal estimate of ten hours explains how it planned the price; it does not turn a fixed offer into an automatically variable hourly bill.
QUOTE Q-041 — USD 800.00 Deliverable: clean and import up to 200 supplied products into one store. Includes: mapping the agreed fields, removing duplicate rows and one correction round for import errors. Excludes: new copy, image creation and additional storefronts. Acceptance deadline: [date, time and time zone]. Delivery schedule and payment terms: [agreed details]. Any change to this scope needs a separate written agreement.
Handle an extra-work request separately
The customer later asks for a second storefront. The studio proposes three additional hours at USD 65, a USD 195 variation. Only if that variation is agreed does this example's combined price become USD 995. Keep the original USD 800 quote and the additional approval; do not replace its file with a USD 995 version and erase the reason for the change.
| Stage | Amount | What the number means |
|---|---|---|
| Estimate E-041 | USD 670–930 | Range based on incomplete information |
| Quote Q-041 | USD 800 | Offer for the defined scope |
| Agreed extra storefront | USD 195 additional | Separately approved work, not an automatic overrun |
Use the right heading and preserve acceptance
Docuivo's quote generator labels its output Quotation; it does not have a separate estimate mode. Use the copyable estimate text in a clearly labelled document, then use the quote editor for the actual quotation. Enter the accepted scope in the item descriptions and notes, and save the acceptance correspondence separately.
The quote-to-invoice control reuses customer details and line items after you confirm acceptance. Review the resulting invoice's payment date and terms; an offer deadline is not its payment deadline.
Check the rules for your transaction
New Zealand's Commerce Commission distinguishes quotes from estimates and explains that significant possible variations should be made clear. Its contract guidance is specific to New Zealand; the examples here do not determine the legal effect of your agreement in another jurisdiction.
