FAQ
I'm not technical. Can I still use what you build?
Yes. Everything comes with plain-English instructions, and I can build it to run from Excel or a simple interface. If you'd like a safety net, add the 30-day written support extra and just message me whenever something isn't clear.
Do you know Incoterms and customs rules, or just the coding?
Both. years of hands-on import/export operations — Incoterms, HS classification, duty-relief regimes, freight and customs documentation.
Is my commercial data safe?
Yes. Send anonymized samples if you prefer — I only need the structure, not your real prices. Nothing is shared or reused.
Can you fix or upgrade my existing spreadsheet instead of rebuilding?
Often yes, and it's usually cheaper. Send it over and I'll tell you honestly which is better.
