Emergency Invoicing System: Under 48 Hours to Launch
How we replaced a failed vendor invoicing portal in under 48 hours and migrated three weeks of data back without downtime.
The Challenge
Lunexco Foods lost access to its vendor invoicing panel, and recovery was estimated at around three weeks. They needed a working invoicing flow immediately, without creating a data mess later.
Key risks included:
- No reliable way to invoice active customers
- Cash flow risk during the outage
- Manual workarounds likely to create errors
- A migration burden once the original system returned
The Approach
1) Temporary invoicing app
We shipped a lean invoicing system in under 48 hours with customer records, pricing, tax logic, and PDF generation.
2) Keep operations moving
During the outage, invoices were still sent on time and all activity was recorded for later migration.
3) Automated migration back
When the vendor portal returned, a custom Chrome extension moved all outage-period invoices back into the original system.
New Workflow
- Use the temporary app for day-to-day invoicing.
- Keep normal delivery and billing operations running.
- Sync historical invoices back once the vendor system is restored.
The Results
- Invoicing recovered in under 48 hours.
- Cash flow remained stable during the outage.
- No spreadsheet-based re-entry was needed.
- Three weeks of invoice history was migrated back cleanly.
They saved our business. We would have been in serious trouble without invoicing for 3 weeks. The Chrome extension for migrating data back was brilliant—it would have taken us days to do manually.

Technical Highlights
- Lightweight cloud-hosted invoicing app
- Automated PDF generation with tax rules
- Structured data capture for migration traceability
- Browser automation for bulk import into the restored platform
Safety & Testing
- Parallel checks before migration
- Dry runs of the extension before production import
- Access controls and audit trails for temporary operations
TL;DR
We stood up a temporary invoicing system in under 48 hours, kept the business billing through a three-week outage, then migrated everything back to the original platform automatically.
