I run a small dairy in Honduras that serves 80 regular clients with a catalogue of 17 products sold on both credit and cash. I need a complete Google Apps Script solution that turns seven Google Sheets into a lightweight ERP I can operate from a laptop or a smartphone—even when the connection drops. Scope of work • Build the following linked Sheets modules: Products, Clients, Sales, Accounts Receivable, Costs, and a Monthly Profitability Summary. • Design interactive HTML sidebar forms that work smoothly on both desktop and mobile screens. Each sale must allow multiple products, automatically apply a 5 L discount for preferential clients, and accept partial or full payments while checking credit in real time. • Accounts receivable logic: a daily clock-trigger highlights the entire row green when current, yellow after 7 days, and red after 15 days. • Provide an offline layer so sales can be captured without internet and auto-sync once connectivity returns. • Generate a monthly profitability report with a full cost breakdown. • Package and deploy the whole project with clasp so I can version-control it and install it quickly on new accounts. Acceptance criteria 1. All seven Sheets created with protected headers and drop-downs where appropriate. 2. Sidebar forms load in under two seconds on Chrome (desktop) and Chrome Mobile. 3. Test scenario: record a multi-product credit sale, apply a partial payment, verify color state change after date manipulation. 4. Offline test: disable Wi-Fi, register a cash sale, reconnect, and confirm data syncs accurately. 5. One-click clasp push/pull documented in a short README. Send me your fixed-price proposal and estimated timeline; I’m ready to start as soon as we agree.

Hi there, I have worked on similar business management and workflow automation systems involving Google Apps Script, custom dashboards, reporting logic, mobile-friendly forms, and spreadsheet-based operational tools, so I can help you build this complete lightweight ERP structure properly. For your project, I will create all linked Sheets modules for products, clients, sales, receivables, costs, and profitability while keeping the flow simple enough to operate easily from both laptop and mobile devices. The part I like here is the real business logic involved — especially multi-product sales, preferential client discounts, partial payments, receivable aging colors, and offline syncing. That is where the structure needs to be planned carefully so the system remains fast and reliable even with daily usage. I will also build responsive HTML sidebar forms for quick sales entry, real-time credit validation, automatic calculations, and proper sync behavior once internet connectivity returns. Once the core flow is stable, I will configure the triggers, reporting system, protected sheets, dropdown structures, and clasp-based deployment setup so future management and updates stay simple. I would request to connect once so I can understand your exact sales flow and how you currently manage receivables and reporting manually. Thanks, Rahul A.

Hi, this project presents an interesting challenge in architecting a lightweight ERP system within Google Sheets that functions reliably offline and on mobile devices. The main engineering risk lies in orchestrating seamless offline data capture and synchronization without data loss or conflicts. I usually structure such systems by separating data ingestion, validation, and synchronization layers to ensure data integrity and responsive UI interactions. My experience with Custom Feature Development & Integration involved closely analyzing existing data flows and implementing robust frontend-backend interactions, which aligns with your need for linked Sheets modules and interactive sidebars. I recommend designing the offline sync with clear conflict resolution strategies and leveraging Apps Script triggers judiciously to maintain real-time status updates. Systems like this require careful version control and deployment automation, which I can help package with clasp and document for easy replication. I can start by outlining the data model and sync pipeline, mapping the agent flow for sales and payments, and reviewing the sidebar form chunking strategy for performance. Thanks, Hercules

Hi , Last week I delivered a near‑identical Apps Script mini‑ERP (offline sales, mobile sidebar forms, clasp), so I’m confident to handle this really well. I would like to know the below. 1) You mention 7 Sheets but list 6. Is the missing module a Sales_Items (line items) sheet, or a Settings sheet? 2) “5 L discount” = 5 Lempiras or 5 liters? Per item or per sale, and only for clients flagged preferential? I think we should. - Store each sale’s line items in a separate Sales_Items sheet; this keeps Sales clean and makes reports fast. - Use IndexedDB in the sidebar to cache clients/products and queue offline sales, then delta‑sync on reconnect for reliability. Lets follow a plan like this. 1) I design the 7 linked Sheets with protected headers, drop‑downs, and AR fields; add the daily clock‑trigger for row colors. 2) I build ultra‑light HTML sidebar forms (vanilla JS), with multi‑product cart, real‑time credit check, partial/full payments, and the 5 L rule. 3) I add an offline queue (IndexedDB + localStorage fallback), detect online status, and auto‑sync safely without duplicates. 4) I create the monthly profitability summary from Sales, Items, and Costs; then package with clasp and a short README (one‑click push/pull). We’ll test the exact scenarios, including the 2‑second load
