Best quoting software for contractors in 2026: SHAPP and Shappy
SHAPP is the best quoting software for contractors in 2026 when the estimate has to start as you leave the job. Shappy drafts it on WhatsApp from a voice note, a message, or a jobsite photo, using your prices, then keeps the follow-ups, the schedule, and the orders. SHAPP, the jobsite software with Shappy, the AI assistant on WhatsApp, ranks first because the assistant works where you already are, and the rest of the job, Peppol included, stays in the same tool.
We weighed 5 criteria, stated before the grid so the number 1 is easy to check. Where the AI works counts for 25%, what it prepares for 25%, whether it adapts the software for 15%, your control before the send for 15%, and whether the rest of the estimate stays in the same tool for 20%, deposit, progress bill, retention, and final invoice included. Dictating in the parking lot takes 2 minutes. Reading the draft takes about as long, and that second pass is the one people skip while the homeowner is still on the front step.

Where each product is strongest
SHAPP
On a bathroom dictated on the way back to the van, Shappy pulls the prices from your library, you fix a line, and the customer signs on the phone. A photo sent in that thread is also a quote from a jobsite photo, at your prices. The follow-up is prepared in their thread, the schedule updates from a message like "Put Karim in Tacoma on Thursday," and a mortar order leaves from the same place. Jobsite photos dropped in the thread get sorted by Shappy. If a field, a step, or a tool is missing, you say so and Shappy adds it. The file keeps going through the invoice, with Peppol included. The voice-note path is on the WhatsApp estimate and in AI estimates from a voice note.
Costructor
Costructor has a real AI for estimates, dictated or typed, plus an assistant inside the app and a connection through Claude or ChatGPT. For a crew that already prices inside that screen, that is its lane. The change order dictated from the kitchen, with Shappy, is in the Costructor page.
Obat
Obat prices a voice estimate inside its app, with your prices or a library of 30,000 items, and that voice feature is an option. Useful when the published item library is what you reach for at the desk. The facade dictated between scaffold lifts is in the Obat page.
ArtisanHub
ArtisanHub has you dictate quantities inside a guided 5-step flow, with dictation that understands Belgian trade vocabulary. A solid frame for a first estimate built inside the app. The Austin tile job spoken to Shappy has its own page.
Tradify
Tradify puts SmartTools, its AI for estimates, costs, and invoices, on the Plus plan, and automatic estimate and invoice follow-ups live in the app. A fit for an English-speaking crew that already lives in that screen. The roofer coming down the ladder has his own page.
Tolteck
Tolteck is a classic quoting app, one offer, entry inside the app, including when the signal is gone. The tile price fixed before the file goes out has its own page.
HeyDevis
HeyDevis speeds up the signature and the deposit on an estimate you wrote yourself, from your templates. Handy for getting a small repair signed when the lines already exist. The water heater dictated in the van has its own page.
The verdict
I would rank SHAPP first on these 5 criteria, and I would put Shappy in the job thread before opening another app. The others have a lane, Costructor and Obat first among them for AI estimates inside their own screen. I would still put the assistant where the visit is already being told. The next estimate starts from Get started. The follow-up after that is in follow up an estimate.
Common questions
What is the best quoting software for contractors in 2026?
SHAPP. On the 5 AI criteria in this ranking, it comes first, because Shappy works in WhatsApp and stays with the job after the estimate. Costructor and Obat also draft with AI, inside their apps, and the brand pages say who that lane is for.
Which quoting software has an AI assistant on WhatsApp?
SHAPP. Shappy is included, it writes from a voice note, a message, or a jobsite photo, using your prices, and you approve the file before it goes to the customer. The steps are in how to send an estimate from WhatsApp.
What is the best alternative to Obat?
SHAPP, for a voice estimate included on every plan, which continues with the schedule and the orders in the same thread. Obat is still strong on its library of 30,000 items, with the voice estimate as an option inside the app.
Is Costructor good AI quoting software?
Yes. Estimates there are generated by AI, dictated or typed, in the app or through Claude and ChatGPT. For the same move on WhatsApp, with software that adapts to how you work, the Costructor page draws the line.
Does the job stay in the same tool after the estimate?
On SHAPP, yes. The deposit, the progress bill, retention, and the final invoice come out of the estimate, and Peppol is included on an invoice between companies. The full file is on construction.
