    I need help turning a handful of manual, repetitive processes into streamlined automations inside N8n. The end goal is to have clean, reusable workflows that pull data from the right sources, trigger at the right times, and provide clear logging so anyone on my team can troubleshoot or expand them later. Here’s how I picture the engagement: • Discovery: We’ll jump on a quick call, map the processes I’d like to automate, and decide which triggers and nodes make most sense. • Build & Iterate: You’ll create the initial N8n workflows (using HTTP Request, Webhook, Function, and any other nodes we decide on), then walk me through a short feedback cycle to refine edge-cases. • Handoff: Once everything runs reliably, I’ll need the .json export...

    I need a small, reliable service that sits between Busy Accounting Software (desktop) and my cloud-based ERP. The goal is simple: every time my ERP creates an invoice, payment voucher, credit note or debit note the same document must appear in Busy instantly—no manual export-import, no delays. My ERP already exposes a well-documented REST API and its data lives in MySQL. Your task is to read the new or updated records, apply the correct field mapping (most fields match one-to-one, but a handful will need custom logic for tax and cost-centre breakdowns) and then push the payload into Busy through the method you know best—SDK, XML import, ODBC or any proven Busy integration technique.

    I have several high-volume financial datasets that need a careful eye before they can be trusted for decision-making. Your first task will be to tidy up the raw files—spot and resolve inconsistencies, fill the inevitable gaps, and confirm every figure lines up across worksheets. Once the data is clean, I’ll lean on you to turn it into clear, executive-ready reports. Think dynamic Excel dashboards, concise tables, and visual summaries that highlight key performance metrics without drowning the reader in numbers. While the whole workflow—from organising and validating through to analysis—matters to me, the reporting stage is where I need the most help right now.
