Invoicing for trades and small service businesses is Billdu's focus, and the listing reads like a roll call of them: painters, plumbers, roofers, HVAC, electricians, landscapers, cleaners and general contractors, all in the US. You create an estimate or invoice on site, send it straight from the phone, and get a notification when the client opens it. Templates take a logo, colours and signature. Online payments via Stripe accept credit cards, Apple Pay and Google Pay. Receipts can be scanned and categorised for expense tracking, and reports show cash flow. There's a product and stock list for adding items to invoices in a tap, a client book that imports from contacts and sends reminders, and sync across iPhone, iPad and desktop. It works offline and syncs later, locks behind Face ID or Touch ID, and can share directly with an accountant. Seven days are free, after which Lite, Standard or Premium plans apply.
Invoicing from the back of a van is the use case. Billdu is aimed at American tradespeople, and the listing names the trades: plumbers, painters, roofers, electricians, HVAC, landscapers, cleaners and contractors. You draft a quote or bill at the job, fire it off from the phone, and learn when the client opens it.
Around that are branded templates, card and wallet payments through Stripe, receipt scanning for expenses, cash flow reports, a stock list for fast line items, and a client book pulled from your contacts that chases late payers. It syncs across iPhone, iPad and desktop, works offline, and can be locked with Face ID or Touch ID.
A job starts with an estimate written in the client's kitchen and sent before you've left the drive. When it's accepted, the same document becomes an invoice with a tap, and a Stripe link lets the client pay by card or Apple Pay on the spot. Receipts from the hardware store get photographed in the van and filed as expenses.
At month end the cash flow report shows what's owed, reminders go out to slow payers, and the accountant gets a share. The offline mode matters on rural jobs where signal drops; everything syncs when it returns.
Tradespeople search for it because chasing payment on paper invoices is slow and getting notified when a client opens the quote removes the guesswork. The on-site estimate workflow and Stripe payments are the features named most. A 4.8 rating from over ten thousand reviewers is high for business software, which tends to attract grumbles.
The five screenshots presumably show an invoice preview with a logo, the estimate builder, a payment screen and a reports dashboard. Business category apps favour clean forms and clear totals, and Billdu's templates let you brand the documents, so the customer-facing output matters as much as the app's own look. Expect a practical, form-driven layout built for thumbs on site.
A version string of 26.10.10 reads as date-based, which puts the build in late 2026 and points to frequent releases. BILLDU LTD is the developer of record. Ten-thousand-plus ratings is a reasonable base for a niche business tool. App Store only on this page, though the listing mentions desktop sync, so there's a web or desktop component beyond the store.
On-site quoting
Estimates written and sent at the job before you've left.
Getting paid faster
Stripe links accept cards, Apple Pay and Google Pay directly from the invoice.
Receipts in a shoebox
Scanning and categorising receipts turns expense tracking into a habit rather than a chore.
Rated 4+ and free to download, but only for seven days; after that you choose a Lite, Standard or Premium plan, with prices not given in the description. An account is needed for sync across devices and for Stripe payments, which carry their own processing fees. It works offline and syncs later. The listing is explicitly aimed at the US, so tax and payment handling elsewhere is unknown. Ads and storage size aren't mentioned.
Our take
Recommended for US contractors and freelancers who invoice from the field and want payments collected in the same flow. It replaces a paper book and a card reader convincingly. Hobbyists invoicing once a quarter won't get value from a subscription, and businesses outside the US should check tax handling before committing.
