BuildWell vs Invoice Fly

Writing the estimate

Invoice Fly: You pick items from your saved list or add new ones with a name, description, price and quantity, then set discounts as a percentage or a fixed amount and tax per item or on the total. Photos from the camera or gallery can go on the estimate, and it goes out by email, link or PDF. When the client agrees, a Convert to Invoice option carries everything over, and every field stays editable. ^[11][9]

BuildWell: You describe the job by voice or text, add up to five photos or a floor plan, and BuildWell asks only the questions that change the price. It shows the plan of work in order first, then builds line items, each a unit of work with its own labor hours and materials. Every quantity, hour and price is editable, and an estimate can be revised, keeping the original, and signed again. ^[10][6]

The difference: Invoice Fly’s help center describes building estimates from the items you save and reuse. BuildWell is built for jobs you need to think through, where the line items and quantities are the hard part. ^[11][10]

Where the prices come from

Invoice Fly: Prices are yours. Invoice Fly’s estimates page describes managing item pricing and markups, and items come from the list you build up as you go. ^[12][11]

BuildWell: Prices come from real local data. Each material is matched to a real product and priced at a store near the job’s ZIP, checked within the last 30 days, and labor is the Bureau of Labor Statistics median wage for that trade in your metro, plus the labor overhead, markups, sales tax and permit fee you set. If a material has no store price, the estimate says so and you confirm it before sending. Prices you type in are saved for next time. ^[6][10]

The difference: With Invoice Fly, prices come from the items and markups you set. With BuildWell, materials and labor come priced for the job’s location, and you adjust from there. If you’ve priced the same work for years, your own list may be all you need. ^[12][6]

AI tools

Invoice Fly: Invoice Fly lists an AI logo maker, and its e-signature page says you can create an estimate manually or let its AI generate one. Its help center also describes a Speech to Invoice template that lets you create an invoice by speaking. ^[5][14][3]

BuildWell: AI does the estimating: it reads your words, photos and floor plan, plans the work and picks quantities, and you can ask it to revise the estimate after your own edits without losing them. It also makes before-and-after renders of the finished room from a photo, and logos. To do that, BuildWell shares job details and photos with Anthropic, Google and OpenAI, which you can turn off in your profile. ^[10][13]

The difference: In Invoice Fly you can enter every detail yourself or start from an AI draft, as its e-signature page describes. In BuildWell the first draft always comes from the AI, with prices from local store and wage data, and every number stays editable. ^[14][10]

Client approval and e-signatures

Invoice Fly: Clients open a link on any device, with no login, and draw or type a signature; Invoice Fly says signatures are time-stamped and describes compliance with the US ESIGN Act and the EU’s eIDAS rules. A Request Sign & Acceptance switch on the estimate marks it accepted once signed and notifies you, and you can add your own business signature to invoices. ^[14][11][21]

BuildWell: Clients open the estimate on their phone, with no app or account, and accept and sign with a finger or decline. Their name and signature print on the signed estimate. You can send the link by text or email, copy it anywhere, share the PDF, or collect the signature in person on your own phone. Invoices can ask for a signature too. ^[15][8]

The difference: Both get a signature without the client installing anything. Invoice Fly describes its signature compliance in detail; BuildWell’s estimate page has accept and decline buttons and shows you how many times it was opened. ^[14][15]

Invoices

Invoice Fly: Invoices carry a number, dates, a PO number, notes, discounts and tax per item or on the total, with your own tax label. Its invoicing page describes recurring invoices, its notifications page describes alerts when an invoice is viewed, paid or overdue, and you set a default currency you can change on any document. ^{[18][5][16][22]}

BuildWell: A signed estimate becomes the invoice with the same lines and totals, or you start one from scratch for a small job. Terms are due on receipt, 7, 14 or 30 days. You can record cash and check payments, void an unpaid invoice and attach job photos and renders, which print after the invoice. ^[8]

Deposits and progress payments

Invoice Fly: You can request a deposit right from an estimate once Stripe or PayPal is connected. Other payments are recorded by hand on the invoice, with the amount, method, date and a note, and a switch marks it paid. ^[17][12][18]

BuildWell: Invoice any percentage of the estimate as a deposit, then progress payments, then the balance, each as its own invoice against the estimate. Every payment is recorded against its invoice, so you always see what’s paid and what’s left. ^[8]

The difference: Both take a deposit up front. Invoice Fly records later payments on the invoice; BuildWell is set up for jobs billed in stages, with each progress payment as its own invoice. ^[8][18]

Online payments and fees

Invoice Fly: Invoice Fly connects your own Stripe or PayPal account, and clients pay by Visa, Mastercard, Amex, Apple Pay, Google Pay, Klarna, ACH or SEPA. Card rates are whatever your Stripe or PayPal account charges; ACH typically costs about 1% and lands within four business days, by Invoice Fly’s description. ^[20][2]

BuildWell: Connect Stripe once and clients choose card or US bank account on the invoice page. Stripe’s fee is passed through at cost, 2.9% + 30¢ for a card and 0.8% capped at $5 for a bank transfer, and BuildWell adds no fee or surcharge of its own. You can also list your Zelle, Venmo, Cash App, PayPal or check details, which print on every invoice. ^[19]

The difference: Invoice Fly’s payment options include wallets, SEPA and Klarna, through Stripe or PayPal accounts you connect. BuildWell takes card and US bank transfer at Stripe’s published rate, plus the off-app methods you list. ^[20][19]

Follow-up and notifications

Invoice Fly: Invoice Fly automates follow-ups on estimates that need a nudge and sends automatic reminders on overdue invoices. You get lock-screen and in-app alerts when an estimate is signed, when an invoice is opened, when a payment arrives and when an invoice goes overdue. ^[12][16]

BuildWell: You see when the client opens the estimate and how many times, and get a notice when they accept, decline or pay. You can resend an estimate or invoice up to five times, so a client isn’t flooded. ^[15]

The difference: Invoice Fly sends reminders for you. BuildWell tells you when the client has looked, so you decide when to call. ^[16][15]

Templates and branding

Invoice Fly: Invoice Fly’s home page describes customizable invoice templates in over six layouts, and its estimates page lists more than seven estimate templates. Its help center describes setting your logo’s size and transparency, a primary color and one of four fonts, choosing which fields show, renaming labels and adding terms. ^[7][12][21]

BuildWell: Six document templates carry your logo and colors, and any estimate or invoice prints in English or Spanish. Signed estimates print the client’s name and signature, and renders print as before-and-after pages. ^{[1][4][15][13]}

The difference: Invoice Fly describes font, field and label settings; BuildWell’s documents print in English or Spanish. ^[21][4]

Devices, language and support

Invoice Fly: Invoice Fly runs on iOS, Android and the web, syncs across devices, and allows the same account on two phones. Its help center says support is by email and describes a Report an Issue button in the app. ^[3][5]

BuildWell: One subscription, bought on the App Store, Google Play or the web, covers BuildWell on iPhone, Android and the web, with everything in sync. On iPhones with LiDAR you can scan a room for its measurements. The app works in English or Spanish, and support is by email from the support page. ^[4][23]
