Honest comparison
Yes, you can do this in Excel.
The honest comparison. Excel is fine for the first 3 months. After that, the silent costs add up faster than the spreadsheet does.
Free during early access · Forever free under 25 orders/day
TL;DR
- Excel works at 1–5 orders/day. The math fits in a sheet, the manifest fits in a print job.
- At 5–25 orders/day, Excel works but the silent-loss cost (missed SLA, slip mismatch, deduction chase) starts to dominate.
- Above 25 orders/day, Excel becomes the constraint — and you start paying ops people to keep up with it.
What they do well
- Fast to set up. Free in the literal sense.
- Customisable to whatever you want it to be
- Works offline; works on the slowest laptop
- Your accountant already understands it
What Robnu actually replaces
- Manifest generation against marketplace SLA windows
- Document pipeline (slip + invoices tied to orders)
- SLA watchdog (clock you can't watch by hand)
- Deduction reconciliation (settlement diffs, with Protect)
Honest note
We won't pretend you can't run this in Excel — early-stage sellers have been doing it for years. The question is what it costs you in silent leakage and ops hours. The calculator on the homepage estimates that.
The hybrid most early sellers run for years — "Excel for everything plus 11 portal tabs" — works mechanically but costs 3–4 hours/day and leaks 5–10% of gross to deductions you don't catch. Robnu absorbs the operating overhead and surfaces the leakage. Free during early access, so the trade is "your time vs. setting up an account."
