CalibrePosted to the ERP you already run.
Calibre works inside your finance stack. It keeps vendors, accounts, tax codes and purchase orders in sync with your ERP, and posts every verified invoice with the codes your team would have chosen.
Supported ERPs
SAP S/4HANA
Most large Indian manufacturers and contractors close their books in SAP.
SAP S/4HANA integration →Tally
Tally runs the books of more Indian businesses than any other system, and purchase invoices are still keyed into it by hand.
Tally integration →Oracle NetSuite
Indian subsidiaries of global groups often run NetSuite OneWorld, with Indian GST to get right on every vendor bill.
Oracle NetSuite integration →Oracle Fusion Cloud ERP
Enterprises on Oracle Fusion Cloud ERP still receive Indian supplier invoices as PDFs, scans and e-invoices.
Oracle Fusion Cloud ERP integration →Infor M3 and Infor LN
Infor M3 and Infor LN run manufacturing and distribution businesses where a single supplier invoice can carry dozens of lines.

New ERP connectors in days, not months.
We built the hard parts of integration once. A new ERP needs only its adapter: authentication and the ERP’s own operations. Mappings, preflight checks, retries, posting and the audit trail are already there, already tested. That is why we can say yes to the ERP you run.
- AdapterAuthentication and the ERP’s own operations. The only part written for each new ERP.
- MappingFields, GL accounts and tax codes. Versioned, with test cases that must pass before a mapping is published.
- PreflightPurchase order, vendor, GL account, tax code, currency, line reconciliation and duplicates, checked before any write.
- EngineA durable queue with retries, circuit breakers, quarantine and blackout windows.
- PostingWrites keyed so they happen once, the PDF attached, and the ERP document number returned.
- AuditEvery request and response kept, with the ERP’s own reply.
Nothing is written twice.
- 1
Trigger
An invoice clears on its own or is approved.
- 2
Preflight
PO open, vendor active, GL and tax code valid, lines reconciled, not a duplicate.
- 3
Write
Posted with its own key, so a retry never makes a second entry. Unresolved lines are held, not guessed.
- 4
Return
The PDF is attached and the ERP document number comes back to Calibre.
Integration questions
How long does a new ERP connector take?
Days, not months. Every connector is built on one platform, so a new ERP needs only its own adapter; mappings, preflight checks, retries, posting and the audit trail are already there.
Can an invoice be posted twice?
No. Every posting carries its own key, so retries and resent invoices never create a second entry in your ERP.
Do we change our chart of accounts?
No. Calibre reads your vendors, accounts and tax codes from your ERP and posts with the codes your team already uses.
See it on your own invoices.
Send us a month of invoices. We replay them against your ERP’s records and show you, vendor by vendor, what Calibre would have cleared, and why the rest would have gone to a person.
