Clamp vs Handoff: AI estimating priced from your own catalogs, with project management on higher plans, or a free AI estimate that carries into a signed residential workflow
Handoff prices AI estimates from catalogs you import, refines them by message, and adds takeoff, payments, budget tracking and time tracking on its higher plans. Clamp starts with a free AI estimate at direct cost and carries it into the signed residential workflow: proposal, milestones, change orders, decisions, invoices and job cost, on every plan.
Direct answer: Handoff starts at $119 a month billed annually, nearly 10 times Clamp Solo at $12.50. Proposals, change orders, invoices and job costing are on every Clamp plan; Assistant adds e-signing and the customer portal for $41.67, about a third of Handoff's lowest plan. Choose Handoff if you want the AI to price from your own price sheets, takeoff from plans, or built-in card and ACH payments.
Describe the job
Itemized draft at cost
Sample data. An AI estimate in Clamp starts with the job described the way you would say it, and the draft comes back as lines at direct cost, grouped by trade, before your markup goes on.

Verdict
Clamp may fit when
- You want to try an AI estimate before you pay anything, and keep the draft at direct cost with your markup applied once
- You run a few residential jobs at a time and want the estimate, proposal, milestones, change orders, decisions, invoices and job cost on one record
- You are one person or a small crew and $12.50 to $83.33 a month billed annually is the budget
- You want change orders, invoices and job costing without stepping up a plan
- You want automatic mileage and time on site recorded against the job
- You work with subs who need the job and schedule without seeing your prices
Handoff may fit when
- You keep supplier price sheets and want the AI to price from them before it falls back to its own numbers
- You want to refine the draft by sending the AI follow-up messages, with saved presets for labor rate, markup and tax
- You bid from residential plans and want AI takeoff up to 7,000 square feet (Scale)
- You want card and ACH payments collected inside the app (Pro)
- You want crew time tracking that feeds labor cost into the project budget (Pro and Scale)
- You want client financing, a subcontractor portal or API access on the higher plans
Before you compare them
- Both products turn a job description into an itemized AI estimate you edit, and both have proposals with digital signature, change orders, invoices and a client portal. The difference is what each includes at its lowest price and how the draft is priced.
- Handoff's lowest plan is Flex at $119 a month billed annually for 2 users and 50 AI credits a month. Clamp's lowest plan is Solo at $12.50 a month billed annually with 3 free AI credits to start; monthly AI credits start on Assistant at $41.67.
- Handoff's budget tab, time tracking, client portal and online payments start on Pro, which carries a 12-month commitment. Clamp's job costing, time on site, mileage, change orders and invoices are on every plan; the customer portal and e-signatures start on Assistant.
- Handoff prices from catalogs you import, then supplier catalogs, then its own AI pricing, with markup and margin set per rate. Clamp drafts every line at direct job cost, uses your saved rate where you have one, and applies one company markup from your overhead and profit goal.
- Handoff processes card and ACH payments on Pro, with the fee covered by the client. Clamp does not process payments; you add your own payment link and record what was paid.
- Handoff does AI takeoff from plans on Scale. Clamp does no plan takeoff.
- Clamp is not accounting software: no general ledger, payroll, bank feeds or tax filing. Neither product's official pages were read for accounting integrations on this page.
- 'Not found' on this page means not found on Handoff's pricing page or Help Center on 2026-10-14. It does not mean Handoff cannot do it another way.
- Neither product was tested against the other. No speed or accuracy claim is made.
Workflow
| Feature | Clamp | Handoff |
|---|---|---|
| AI estimate from a description | Describe the job in plain words; the draft lists what it included, excluded and assumed. One free on the website; 3 free credits in the app, then 25 a month on Assistant and 50 on Teams | Describe the job in the AI chat, with voice transcription; 50 credits a month on Flex, unlimited on Pro and Scale; each credit is one AI interaction |
| Revising the draft | Type or say what to change; Clamp changes only that, keeps numbers you typed and shows each change with its price before you apply it. Half a credit | Follow-up messages refine the estimate, such as adding labor at a rate or removing a section; or edit any row in the table |
| Whose prices fill the lines | Every line at direct job cost; your saved rate replaces the baseline line by line. No price-sheet import | Your custom catalog first, then supplier catalogs, then AI pricing; catalogs import from a PDF, Excel, CSV, Word file or an image of a price sheet. 1 catalog on Flex, unlimited on Pro |
| Markup | One company markup from your overhead and profit goal, applied once and shown apart from the direct cost | Line markup, profit margin and tax set per catalog rate; default markups for labor, material and other saved as presets |
| Saved AI instructions | Not offered; rates are saved in the app and the markup is set once | Presets for labor rate, markups, tax and below-the-line fees, applied to every estimate unless overridden in the chat |
| Plan takeoff | Not offered | AI takeoff from residential plans up to 7,000 square feet, on Scale; measures and counts quantities and fills the estimate |
| Lead qualification | A five-question lead score on the first call, every plan | Projects and clients are saved; a lead-scoring workflow was not found on Handoff's pricing page or Help Center |
| Proposal and e-signature | Proposals on every plan; signed in the customer portal on Assistant and Teams | Proposal sent by SMS, email or link; signed proposals carry a timestamp and digital signature; clients can decline and leave feedback |
| Change orders | Every plan: priced and billed, e-signed in the portal on Assistant and Teams, and the contract total updates | A change order linked to the proposal, built by hand or from the AI chat; the client approves online and project totals update; no plan limit stated in the article |
| Customer decisions after signing | A Decisions needed list: needed by, what it blocks, who owes the answer, the resolution; answered in the portal on Assistant and Teams | Up to 5 estimate options per proposal on Scale, and option and add-on selections the client makes before signing; a decision request after signing was not found on Handoff's pricing page or Help Center |
| Progress billing | Milestones tied to job events, each with a checklist of evidence; invoices follow the payment schedule | A payment schedule on the proposal: deposit, milestone and final entries by percent or amount, each turned into an invoice once the client approves; no plan limit stated |
| Payments | Not processed by Clamp: add your own payment link and record what was paid | Card 2.85% and ACH 1% capped at $10, covered by the client, on Pro; off during the trial |
| Job costing | Every plan: receipts, vendor bills, time on site and labor against the estimate, reviewed at close | Budget tab: approved estimates plus change orders against confirmed expenses, with variance by line, section and group. Pro only |
| Time tracking | Automatic time on site recorded against the job, every plan; not a GPS crew clock with geofencing | Crew clock in from a phone and pick the project; approved labor cost can be added to the budget. Pro and Scale, in beta |
| Business mileage log | Automatic trip detection, confirmed per trip, at the IRS rate for its date, every plan | Not found on Handoff's pricing page or Help Center |
| Customer portal | Sign, view invoices, photos and schedule, answer decisions; Assistant and Teams | Proposals, invoices, documents and daily logs in one place, enabled per project; requires Pro |
| Team and subcontractor access | Up to 10 accounts on Teams, plus unlimited free sub invites who never see your prices | 2 users on Flex, 5 on Pro; an AI subcontractor portal on Scale |
| Phone app | iOS and Android on every plan | iPhone, Android and the web; a Room Scan beta for iPhone |
What was and was not tested
What was compared: Hands-on testing of either product. Neither was tested against the other, and no speed or accuracy claim is made. Documented, not tested.
| Statement | Basis |
|---|---|
| Published by Clamp, using each product's own pricing pages and documentation. | Clamp's own statement |
| One person, entry plan, billed annually: Handoff Flex is $1,428 a year (calculated) for 2 users and 50 AI credits a month; Clamp Solo is $149.99 with 3 free AI credits to start, and Clamp Assistant, the first plan with monthly AI credits, is $499.99 with 25 a month. | Calculated from published prices |
| Five people with job costing and a customer portal, billed annually: Handoff Pro is $2,868 a year (calculated) with a 12-month commitment; Clamp Teams is $999.99 for up to 10 accounts. The plans are not equivalent: Pro includes unlimited AI credits, catalogs, payments, financing and crew time tracking that Clamp does not offer, and Teams includes lead scoring, milestones, decisions, mileage and free sub access that Handoff does not document. | Calculated from published prices |
| Handoff's prices on 2026-10-14 match its 2026-10-11 reading: no change. Its pricing page lists annual-billing figures and a 20% annual saving; the monthly figures come from the billing article. | Verified against a published source |
| Handoff's pages do not agree on plan names everywhere: the Help Center overview calls client financing a Business feature, while the pricing page lists it under Pro. The pricing page is used here. | Verified against a published source |
Switching
- Export your clients, estimates, proposals and invoices from Handoff before you cancel; Pro and Scale carry a 12-month commitment, so check your renewal date first.
- Do not assume Handoff catalogs or estimate history can be imported into Clamp; Clamp has no price-sheet import, so plan to save your rates in the app as you price your first jobs.
- If you collect card or ACH payments inside Handoff, set up your own payment link before you switch.
- If your crew clocks in with Handoff time tracking, decide whether Clamp's automatic time on site is enough; it is not a crew time clock with geofencing.
- Finish open jobs where they started; start new ones in Clamp, beginning with the free AI estimate.
Questions
How do Handoff and Clamp compare on included AI credits?
Handoff Flex includes two users and 50 AI credits a month for $149 a month, or $119 a month billed annually. Clamp Assistant includes 25 AI credits a month plus the customer portal and e-signing for $49.99 a month or $499.99 a year. Handoff counts one credit per AI interaction, while a Clamp estimate is 1 credit and a revision half, so the counts are not directly comparable.
How much is Handoff for two users or a small crew?
Handoff Flex is $149 a month, or $119 a month billed annually, for two users. Pro covers five users at $299 a month, or $239 billed annually, with unlimited AI credits and pricing catalogs, time tracking and online payments. Pro and Scale carry a 12-month commitment, so compare the commitment as well as the monthly price. Clamp Teams covers up to 10 accounts for $83.33 a month billed annually.
Can I type a bathroom remodel into Handoff and revise the estimate?
Yes. Handoff takes a bathroom-remodel description with dimensions and fixtures and lets you refine the estimate through follow-up messages or line edits. Clamp also drafts from a plain description, listing inclusions, exclusions and assumptions at direct cost with markup shown separately. Neither draft should go to a customer until you have checked the scope, quantities and prices.
Which Handoff plan includes the customer portal and change orders?
Handoff's client portal starts on Pro. Its change-order help article names no plan limit, but its trial article lists change orders among Pro features, so confirm before buying Flex. Handoff's customers approve change orders online and project totals update. Clamp has change orders on every plan, with the customer portal and e-signing on Assistant and Teams.
Does Handoff measure quantities from plans, and does Clamp?
Handoff offers AI plan takeoff on its Scale plan, which measures and counts quantities from drawings into an estimate. Clamp does not do plan takeoff; you give it the dimensions in the job description. Check Handoff's current plan-size limit before relying on it, and don't treat an uploaded drawing in any app as a finished quantity takeoff.
Does Handoff work offline at the jobsite?
Offline use is not described on Handoff's help pages, and its AI chat shows a Network Unavailable error without a connection. Clamp's leads, estimates, proposals, change orders and invoices work with no signal on every plan; AI drafts, e-signing and the customer portal need a connection when you use them. If your jobs have poor reception, test offline use before you commit.
