Every evening I find myself tapping numbers into a phone notepad just to split a single invoice in two—one total for the merchant, the other divided equally among a group of customers that can change from day to day (often eight, but not fixed). I want to retire that manual routine and replace it with a simple mobile app that does the math and stores the results for me. Here is the flow I have in mind: • I enter the full invoice amount and the head-count of customers. • The app instantly shows two figures: 50 % for the merchant and an equal share for each customer. • One tap saves the record and, ideally, generates a clean PDF or image of the split invoice for sending or printing later. • All past entries stay searchable by date, amount, or customer count so I can reconcile accounts at month-end. Must-have features: automatic invoice generation, clear division and distribution logic, and reliable record keeping. A lightweight, intuitive interface is more important to me than fancy graphics, but accuracy and speed are essential. I’m only considering freelancers who can point to relevant experience creating finance or billing tools on mobile. If you have previously shipped something similar—whether in Flutter, React Native, Kotlin, Swift, or another modern stack—let me know how it solved a comparable problem and what you’d do differently for this project. Acceptance criteria will be straightforward: the app performs the split calculation correctly, stores each transaction, and exports a neatly formatted invoice without crashes on current Android and iOS versions. Once that’s solid, we can discuss any extra bells and whistles, but the core must ship first. If this sounds like a quick win for you, tell me how soon you can prototype and what you’ll need from my side (logo, color palette, sample invoices, etc.). Looking forward to finally putting my notepad to rest

Hello, This is a straightforward but highly practical app, and I can help turn your manual invoice-splitting process into a fast, reliable mobile solution. I would build a lightweight Android/iOS app in Flutter that instantly calculates the merchant's 50% share and evenly distributes the remaining amount among customers, with one-tap saving of records. The app will include transaction history, search and filtering by date/amount/customer count, and PDF invoice generation for easy sharing or printing. My focus will be on accuracy, speed, and a clean user experience rather than unnecessary complexity, ensuring the core workflow takes only a few seconds. I can provide an initial prototype quickly and would only need your logo, preferred branding, and a sample invoice format to get started. Thanks

Hello there, I will build your invoice-splitting app in Flutter — input screen, instant 50/50 merchant split with equal customer shares, one-tap PDF export, and searchable transaction history across Android and iOS. For the PDF, I will generate it using structured templates so each exported invoice stays print-ready and consistent — no layout drift between devices. Questions: 1) Do you need any cloud sync, or is local storage sufficient? 2) Should the PDF include your business logo and branding? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Looking forward to your response. Best regards, Kamran

Hi there, I have read your project requirements and understand that you need a simple and reliable mobile application that calculates invoice splits, stores transaction history, and generates professional PDF or image invoices for future reference. The focus is on accuracy, ease of use, and seamless performance on both Android and iOS. We have experience developing business and finance-related applications with record management, PDF generation, and reporting features, and can deliver a clean and intuitive solution with searchable transaction history and export functionality. A few questions before proceeding: ============================ Do you need user login and cloud backup, or will the data be stored locally on the device? Should the generated invoices include your logo and custom branding? Would you like the app to support sharing invoices directly through WhatsApp or email? Do you have sample invoices or preferred invoice formats for the PDF generation? Best Regards, Srashtasoft Team

Hi, this is a small mobile workflow, but the value is in getting the transaction model and export behavior exactly right so it stays dependable under daily use. The real engineering risk is not the split math itself; it’s making rounding, persistence, and invoice export deterministic so the saved record always matches what gets searched, shared, or printed later. I’ve built several production systems where correctness, validation, and clean operator flow mattered more than flashy UI. In a React Native-style app like this, I usually keep the core calculation rules isolated from the screen layer so the math, saved history, and export output all use the same source of truth. The closest relevant work in my background is NYSE Day Trading Bot Development for precision-sensitive financial logic, and Squarespace Checkout Streamlining for Meal Service -- 2 for strict user-flow validation and error prevention. I’d structure this with separate layers for calculation, local record storage, and invoice rendering/export. That keeps the core shippable first, while leaving room for later additions like branding, sync, or filters without rewriting the logic. These are the kinds of systems I design for long-term production use, even when the first release is intentionally lightweight. If useful, I can sketch the transaction model, search fields, and export flow before build starts. Thanks, Hercules

Hi There!!! ★★★★ (I can build a lightweight, accurate invoice-splitting mobile app with clean UI, fast calculations, and reliable financial record storage.) ★★★★ I carefully reviewed your project and understand that you need a simple mobile app that splits invoice totals into merchant share (50%) and equal customer shares, allows quick entry, saves records, and generates downloadable PDF/image invoices. The app should also keep searchable history for easy monthly reconciliation with high accuracy and speed. ⚜ Invoice Splitting Mobile App Development ⚜ Real-Time Calculation Logic (Merchant + Customer Split) ⚜ PDF / Image Invoice Generation ⚜ Transaction History & Search Functionality ⚜ Cross-Platform App Development (Flutter / React Native) ⚜ Clean & Minimal UI/UX Design ⚜ Data Storage & Record Management System I have experience building utility and finance-based mobile applications with focus on precision, performance, and smooth user experiance. My approach would be to develop a simple but robust calculation engine first, then build a clean UI around it, followed by secure local/cloud storage and export functionality. I typically use Flutter or React Native with SQLite/Firebase depending on scalability needs. I’d be happy to quickly prototype this and would like to know if you have any preferred invoice format or branding style.

Hi, I can build a lean, reliable mobile app that does the split, stores records, and exports invoices for Android and iOS. I have shipped finance and billing tools with Flutter and React Native and have delivered apps that compute a fixed merchant share and equal customer shares, save transactions, and generate PDFs or images for sharing. The MVP flow: enter full amount and headcount; app shows 50% for merchant and equal shares per customer; one tap saves the record and creates a clean PDF invoice; past entries are searchable by date, amount, or headcount. I will make it offline ready with local storage and sync when online, and ensure smooth performance on current Android and iOS versions. The UI will be minimal and fast, focused on accuracy over visuals. I can prototype a working Android and iOS build in about 1 to 2 weeks once branding assets are provided. From you I will need a logo, a color palette, a couple sample invoices to match the layout, and any preferred PDF template notes. After MVP, we can add optional features like improved filters or batch exports. Best, Justin

Plan: a lightweight mobile app to replace your notepad. I’ve shipped finance tools on mobile using Flutter and Kotlin, with native Android exports for invoices. The core logic will compute merchant = 50% and per-person share = total/headcount, store each entry, and export a clean PDF or image. All records will be searchable by date, amount, or headcount to help month-end reconciliation. The UI will be fast and simple, keeping errors and crashes away. Key questions I’d like to confirm: Will multi-currency support or tax rounding be needed? Do you want PDFs or image exports? Would you prefer a cloud-backed sync or complete local storage for invoices, and which backend would you like to use (e.g., Firebase, REST API)? Would you like me to use your logo and color palette, or should I propose a clean theme?

I can see why you're still reaching for a notepad—this is exactly the kind of repetitive calculation that should happen instantly and leave behind a clean audit trail. I’d start by keeping the first version focused on the core workflow: invoice amount in, customer count in, then immediately calculate the merchant’s 50% share and the per-customer amount with proper rounding so totals always reconcile correctly. Once that’s solid, I’d add one-tap saving, searchable history, and PDF/image invoice generation from the same stored record to avoid mismatches between displayed and exported data. For reliability, every transaction would be stored locally and structured for fast filtering by date, amount, or customer count. A small but useful improvement would be saved defaults for common customer counts while still allowing quick edits when the group size changes. I previously worked on billing-focused business tools using Python and PHP where accuracy, record keeping, and exportable documents were the priority over visual complexity. Do you already have a sample of the invoice layout you’d like the PDF/image export to follow, or should I design a clean default version? I can start on the prototype immediately.
