I need a full-stack developer who can build a lightweight web-based accounting system and a companion iOS app that mirror the core screens. The solution will revolve around four daily workflows: • Sales: I will type sales figures directly or bulk-import them from an Excel sheet. They are always separated into Cash, Card, and Apps. • Purchases: I add suppliers with tax number, address, and phone, then attach their invoices. After taking a photo of each invoice, the system should read the image and auto-fill line items (item, description, quantity, unit price, VAT, total). Each invoice stays “Pending” until I mark it “Paid”. • Expenses: simple entry of Electricity, Rent, or Other with date and amount. • Payroll: for every employee I’ll store Name, ID No., ID expiry, Salary, and Bonus. At any moment I must be able to export purchases, expenses, or full ledgers back to Excel. Tech freedom is yours, but the web app must run smoothly on a shared hosting environment and the iOS app should share one central database through a clean API. Efficiency, clean UI, and solid OCR accuracy are what will win this job.

Hi — Elias here from Miami. I see you're looking for a developer to create a web-based accounting system and companion iOS app. It sounds like a project that could really streamline your operations. One common challenge with accounting systems is ensuring they’re user-friendly while also handling complex data. It's crucial to strike that balance. Another issue is integrating with existing tools or services, which can complicate things if not planned well. My approach would start with understanding your specific requirements and the workflow you envision. From there, I would focus on building a clean, intuitive interface while ensuring robust backend functionality. Regular feedback will be key to keeping everything aligned with your vision. To move forward, could you share what specific features you're prioritizing for the accounting system? Also, are there any existing systems or platforms you want to integrate with? Looking forward to your thoughts.

Hello, I will build the web-based accounting system — sales entry with Excel import, purchase management with OCR invoice scanning, expenses, and payroll — along with a companion iOS app sharing one central API. For OCR, I will process invoice photos server-side using Tesseract with pre-processing (deskew, contrast normalization) to reliably extract line items, VAT, and totals. This keeps the iOS app lightweight and ensures consistent accuracy regardless of device. Questions: 1) What shared hosting environment are you on — cPanel with PHP/MySQL, or something else? 2) Roughly how many suppliers and invoices per month should the system handle? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Ready to start whenever you are. Kamran

Hello, I will build a RESTful API–based system with a normalized relational database to manage all financial modules (sales, purchases, expenses, payroll) from a single source of truth. Authentication will use JWT with secure session handling, and all operations will be transactional with ACID compliance to ensure data integrity. Invoice processing will use an OCR pipeline (Google Vision API / AWS Textract) with background job queues to extract and structure line-item data from uploaded images without blocking the system. The platform will include a workflow engine for invoice status management (Pending → Paid), full audit logs, and secure file storage linked to database records. Excel import/export will be implemented for all ledgers, and the same API layer will power both the web app and iOS application for synchronized, real-time data consistency with scalable, modular backend architecture.

Hi, I can build this for you. Laravel backend on shared hosting with a REST API, Swift iOS app connecting to the same database. For the OCR piece I'd use Google Vision API to read invoice photos and auto-fill line items. The four modules (Sales with Excel import, Purchases with invoice scanning, Expenses, Payroll) are straightforward CRUD with status tracking and Excel export via Laravel Excel. Clean, mobile-friendly UI on the web side too. I'm Edward, happy to discuss the details whenever you're ready.

Hi, this is really two systems that need to behave like one: a lightweight accounting backend with clean operational workflows, and an iPhone client that mirrors the core screens without creating data drift. The real engineering risk is not the forms themselves; it’s keeping OCR-derived purchase data accurate enough that invoice ingestion does not create reconciliation problems downstream. I’ve built several production systems like this where the backend model matters more than the surface UI. With a scope like yours, I usually structure sales, purchases, expenses, payroll, and exports around a single normalized ledger model with clear status transitions and auditability. The closest examples in my past work are Custom Feature Development & Integration and HubSpot CRM Implementation & Interactive Senior Living Website. Both required translating business workflows into maintainable database-backed applications with reliable handoff and clean user flows. I’d recommend separating invoice ingestion, accounting records, and mobile/web presentation layers. For OCR, I typically design a review step with confidence thresholds so extracted line items remain editable before posting. That keeps the system usable on shared hosting while preserving one central API and database for the web app and iPhone client. If useful, I can sketch the data model and invoice ingestion flow first, including Excel import/export boundaries. Thanks, Hercules
