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 โ 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 โ 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 โ record cash in and cash out against a client, a job or a debt, and it lands on their account automatically. Debts both ways โ money you are owed and money you owe, each tied to a person, with instalments. Jobs and projects โ revenue against cost, materials apart from labour, so you can see which work was worth doing. Assign workers and pay by the day. Expenses โ categories, receipts, recurring costs like rent and wages, and the ones you bill back to a client. Repairs โ 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 โ 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.

Verdict
The clearest difference is in-app purchases: QuickPDFSign at none against InvoicePro's 6. InvoicePro's advantage is update cadence (every 8 days vs every 4 weeks). On price, ads, device support and iOS requirement there is nothing between them.
