Everything the estimate software does
Line by line
Description, quantity, price and tax on every line, with your logo on the PDF.
Your default terms
Validity, terms and payment method filled in for you, and changeable on each estimate.
A link for your customer
They view the estimate, download the PDF and sign it with a finger or decline it.
Know when they look
See when the estimate was opened, and get a notification when it’s opened, accepted or declined.
Versions
Change an estimate after sending it and the next version goes out, so nobody argues about which one was signed.
Expiry on its own
When the validity date passes, the estimate is marked as expired.
From estimate to invoice
Invoice the total, a deposit or the balance with one click. Nothing gets retyped.
Sales tax your way
The rates you set up (state, county, city) are applied on every estimate and invoice.
Payments on record
Record what the customer paid, by cash, card or bank transfer, and see what’s still open.
Send your estimate late and someone else gets the job
Most homeowners call two or three companies. The one that sends a clear, professional estimate first, while the visit is still fresh, usually gets the call back. An estimate typed up at night in Word and emailed as an attachment often arrives after a competitor’s.
Estimate software lets you build it on your phone before you leave, send a link the customer can sign on theirs, and turn it into an invoice without typing it again.
A real estimate, from the front door to the invoice
Example: a water heater swap. At the customer’s house you add three lines: the 50-gallon heater, labor and haul-away of the old unit. Total $1,480 before tax.
You send the link from the driveway. Twenty minutes later you get a notification: opened. That evening, another one: accepted, with the customer’s signature.
The morning of the job you invoice it with one click, with the sales tax you set up already applied, and when the customer pays by card you record the payment. The receipt goes out by email as a PDF.
Write lines your customer understands (“Haul away and dispose of old water heater”) instead of internal codes. A clear estimate gets signed faster.
Word, Excel or text messages vs. estimate software
| Task | Word, Excel or texts | Gremio Software |
|---|---|---|
| Building it | At night, from a template | On your phone, at the customer’s door |
| Sending it | An attachment that may never be opened | A link, with notifications when it’s opened |
| Approval | “Sounds good” in a text | E-signature, saved with the estimate |
| Changes | A second file with a similar name | Automatic versions |
| Invoicing | Retyped into another program | One click: total, deposit or balance |
Is a free template enough for you?
If you send a couple of estimates a month, a good template may be all you need. We share one, with every section an estimate should include, on our free estimate template page. Once you’re sending several a week and chasing signatures, the software saves you real time.
Which trades this estimate software is for (and when another version fits better)
- Plumbers, electricians, HVAC techs, painters, handymen, installers and landscapers who quote one job at a time.
- Cleaning companies quoting one-off jobs (for recurring service, see cleaning business software).
- Remodelers who need sections and takeoffs: see construction estimating software.
What it doesn’t do today: take payments online, chase unanswered estimates with automatic reminders, or compare two versions side by side.

Frequently asked questions
Can my customer sign on their phone?
Yes. They open the link, review the estimate and sign it with a finger, or decline it.
Will I know if they opened it?
Yes. You see when it was opened and get a notification when it’s opened, accepted or declined.
Can customers pay online?
No. Gremio Software doesn’t process payments. You record what the customer paid (cash, card or bank transfer) and see what’s still open.
Does it send reminders for unanswered estimates?
Not today. You can see whether the customer opened it, so you know when to follow up.
How much does the estimate software cost?
US$16.95 a month, one plan with every feature included, month to month: cancel anytime.
