InvoicePro
Read full descriptionHide full description
InvoicePro is an invoicing and bookkeeping app for tradespeople, contractors and small businesses who bill on site and want one place for what they are owed. Write an invoice or a quote in under a minute, send it by WhatsApp, email or AirPrint, and know the moment it is paid. WHAT IT DOES Invoices and quotes — line items, tax or VAT, discounts, deposits, serial numbers, and your own numbering. Convert an accepted quote into an invoice in one tap. Client accounts — every client has a file: what they were charged, what they paid, what is left. Print a statement, or a one-page sheet of everyone who owes you, biggest first. Receipt and payment vouchers — record cash in and cash out against a client, a job or a debt, and it lands on their account automatically. Debts both ways — money you are owed and money you owe, each tied to a person, with instalments. Jobs and projects — revenue against cost, materials apart from labour, so you can see which work was worth doing. Assign workers and pay by the day. Expenses — categories, receipts, recurring costs like rent and wages, and the ones you bill back to a client. Repairs — a workshop module for anyone who fixes equipment: brands, models, fault codes, serial numbers, photographs, and a printable job card that carries no customer prices. Reports — a daybook of every movement, weekly, monthly and yearly summaries, profit, receivables and aged debt. BUILT FOR REAL CONDITIONS Works offline, and syncs through your own iCloud when you turn it on. Prints to AirPrint and to Bluetooth thermal receipt printers. 45 languages, including full right-to-left Arabic and Hebrew layouts, and Arabic receipt scanning. Your data stays yours: export a complete backup whenever you want. WHO IT IS FOR Electricians, plumbers, builders, solar installers, mechanics, repair shops, cleaners, photographers, consultants, and anyone else invoicing from a van or a workshop. QUESTIONS Does it need an internet connection? No. Everything works offline and syncs when you are back on. Does my data leave my phone? Only to your own iCloud account, and only if you switch it on.

TURN A DAY'S WORK INTO A PAID INVOICE. HAMMR is the offline-first invoice maker, estimate app and job tracker built for handymen, independent contractors and tradespeople. Clock in at the job site, log the work as it happens, and send a clean PDF invoice before you leave the driveway. FROM CLOCK-IN TO PAYMENT - Start a live timer for each job and see hours and earnings as you work. - Log mileage, materials, receipts, notes and site photos in one job record. - Pin your location at clock-in and capture a client's on-site signature. - Keep working without a signal. HAMMR saves everything on your device first. ESTIMATES AND INVOICES - Create a professional estimate before the work starts. - Mark it approved or declined, then convert an approved estimate into an invoice. - Build invoice line items from labor, mileage and materials, or add custom charges. - Apply tax and flat discounts, set due dates and generate a polished PDF. - Share estimates and invoices through Mail, Messages or any app in the iOS share sheet. KNOW WHAT IS PAID - AND WHAT IS NOT - Record deposits and partial payments while HAMMR tracks the remaining balance. - See collected revenue, outstanding invoices, overdue balances and unbilled work. - Add Venmo, PayPal or Cash App payment links and QR codes, plus Zelle or check details. - HAMMR never processes your client's payment, so it adds no payment gateway fee. READY FOR TAX TIME - Review tax collected, material spend and month-to-date or all-time totals. - Export a clean CSV for your accountant. - Export a PDF bundle of invoices, including signed copies. BUILT FOR INDEPENDENT TRADES HAMMR fits handymen, plumbers, electricians, painters, landscapers, carpenters and other solo contractors who need a simple field tool - not a heavy office system. YOUR WORK, YOUR DATA Core job tracking, invoicing and exports work on-device. Create a full JSON backup whenever you need it. HAMMR Pro adds optional cloud backup and multi-device sync after you sign in with Apple or Google. Download HAMMR and move from clock-in to invoice without rebuilding the day from memory. HAMMR Pro is available as a monthly auto-renewing subscription or lifetime purchase. Pricing is shown before purchase. The monthly subscription renews unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your Apple ID settings. HAMMR is a record-keeping tool, not accounting, tax, legal or payment-processing advice. You are responsible for the records and payment details you create.
