How to Convert a Proforma Invoice into a Commercial Invoice (Without Retyping)
Every retype is a chance to change a quantity, price, or product name by accident. Here's what should carry over from proforma to commercial invoice, and what to double-check before it goes out.
By the time a deal is firm enough for a commercial invoice, most of the work is already done — it was done when the proforma was drafted. And yet a lot of exporters retype the whole thing: buyer details, goods descriptions, quantities, pricing, all re-entered by hand into a new document. Every retype is a fresh chance to change a quantity, a price, or a product name without meaning to. (New to the two documents? Start with proforma vs commercial invoice.)
Why exporters re-type the same shipment twice
Usually it's because the proforma and the commercial invoice were built in different tools, or the same tool but with no real link between the two documents — the proforma exists as a PDF, and the commercial invoice starts as a blank template. There's no structural reason this has to happen twice; it's a workflow gap, not a requirement of the documents themselves.
What should carry over, and what shouldn't
Buyer and seller details, goods descriptions, quantities, and agreed pricing should carry over unchanged unless both sides have agreed to and documented a real change. What shouldn't carry over unexamined: the document type label itself (a proforma clearly marked as indicative shouldn't quietly become a commercial invoice with the same disclaimer language), and anything genuinely provisional on the proforma — an estimated ship date, for instance — that should be firmed up, not just copied as-is.
Where mismatches creep in during manual conversion
The common failure points: a quantity that gets fat-fingered while retyping, a unit price rounded differently the second time, or a product description shortened slightly for the new document in a way that no longer matches the proforma the buyer already has on file (and that a bank may be comparing against, if an LC was opened based on it).
Converting in Bilexor: one shipment record, two documents
Bilexor treats the proforma and the commercial invoice as two documents generated from the same underlying shipment record, rather than two independently typed files. Converting carries goods, quantities, pricing, and shipment details forward automatically, and links the two documents so the relationship between them is traceable later — useful if a bank or buyer asks whether the commercial invoice matches what the LC was opened against.
What to double-check before sending the commercial invoice
Even with an automatic conversion, confirm anything that was genuinely provisional on the proforma is now firm: final quantities if the order changed, exact ship date, and any pricing adjustment both sides agreed to since the proforma went out. See our proforma invoice guide and commercial invoice guide for what belongs on each.
