"Send a proforma for accounting validation before wire transfer." "Your proforma does not mention our intra-EU VAT number." "We paid based on the proforma, where is the final invoice?" The proforma invoice is neither an informal quote nor a standard invoice: it is an intermediate document that blocks B2B orders, exports, and transfers if poorly handled.
Payflo points out that in France, the proforma has no accounting or legal value, does not create a payment obligation, and that a transfer received based on a proforma requires the immediate issuance of a final invoice (Payflo, proforma 2026). Yousign specifies that it is mainly used to structure the commercial agreement before commitment, especially for export and down payments (Yousign, proforma vs definitive 2026).
This guide #321 covers proforma invoice customer support: requests, validation before payment, conversion. Distinct from VAT questions (#160) and Net terms (#234): here we cover the proforma case before cash collection.
Summary
Why do proforma invoices generate so many support tickets?
The proforma falls between a quote and a final invoice. The professional client needs it to validate a budget, obtain an internal PO, open a customs file, or initiate a bank transfer. Your support becomes the bottleneck if no one knows who issues it, how long it takes, and what details to include.
Three recurring pain points
Purchase urgency: accounting blocks the transfer without a document
Document confusion: proforma mistaken for an invoice to be paid
Discrepancies in details: VAT, Incoterm, PO, incorrect company name
Typical volume
On a DTC store with 15 to 40% B2B or export revenue, 5 to 12% of finance tickets relate to proformas, formal quotes, or "invoice before payment". Ramp notes that proformas are used primarily for B2B transactions, exporters, and project service providers (Ramp, proforma 2026).
Principle #321
PROFORMA-LOOP pipeline: request → qualification → PROFORMA-DOC issuance → client validation → payment receipt (deposit or balance) → conversion to final invoice.
How does it differ from VAT #160, Net terms #234, and the B2B quote?
Five neighboring pieces of content, five distinct documents.
VAT Questions (#160)
VAT and invoice (#160): tax-inclusive/tax-exclusive, reverse charge, VAT number on final invoice. The #321: non-accounting preliminary document for validation prior to transaction.
Net terms (#234)
Payment terms (#234): post-delivery due date, account credit. The #321: document prior to first payment, often wire transfer or deposit.
B2B Support (#50)
B2B Support (#50): accounts, RFQ quotes. The #321 focuses on the proforma workflow and accounting validation tickets.
Wire Transfer (#322)
Wire transfer support (#322): reminders, WIRE-PROOF evidence, Pending reconciliation. The #321 covers the proforma as an upstream document of the wire transfer flow.

Which PROFORMA-INTENT taxonomy should be used to route requests?
The PROFORMA-INTENT taxonomy prevents treating every "invoice" request as a tax WISMO.
10 proforma intents
pf_request_new: proforma request before order or paymentpf_request_update: modify quantities, prices, address on existing proformapf_mentions_fix: VAT, SIRET, PO, Incoterm, company namepf_validation_status: "accounting has validated, can we pay?"pf_vs_devis: difference between quote / proforma / invoicepf_export_customs: customs, goods value, HS codepf_deposit: deposit based on proformapf_paid_no_definitive: wire transfer completed, final invoice missingpf_expired: expired proforma, renewal of price/lead timepf_convert_order: convert validated proforma into Shopify order
Helpdesk tags
proforma, sub-tags by intent. Escalate to finance if amount > threshold or export outside the EU. Stripe points out: proforma facilitates B2B PO before payment release (Stripe, proforma B2B 2026).
What must the internal PROFORMA-POLICY document contain?
The PROFORMA-POLICY document aligns support, finance and commercial on who issues what, in how much time.
12 policy blocks
Eligibility: Validated B2B, export, high cart value, custom-made; no standard B2C card
Amount threshold: auto proforma if > €X or on request
Issuance SLA: 24 business hours standard, 4 hours urgent export
Validity: 15, 30 or 90 days (Business Info: set by seller)
Owner: support collects info, finance issues PDF
Template: logo, visible "Proforma invoice" mention, not "Invoice" alone
Mentions: seller, buyer, Registration/VAT number, description, qty, Unit Price excl. tax, VAT, total, export Incoterm
Deposit: % authorized, deposit invoice mandatory if payment received (Keobiz CGI art. 289)
Conversion: validated proforma → draft order or payment link
Payment received on proforma: issue final or deposit invoice within 48 hours
Numbering: PRO- prefix separate from final invoices
Archiving: link proforma ↔ order ↔ final invoice
French legal reminder
Payflo: never book the proforma; payment received = immediate final invoice (Payflo 2026). Yousign: proforma does not trigger VAT; deposit invoice does if deposit is received (Yousign 2026).
How to run the PROFORMA-WORKFLOW in 7 steps?
The standard PROFORMA-WORKFLOW standardises each request from ticket intake to paid order.
7 operational steps
Qualification: PROFORMA-INTENT, amount, country, existing B2B account?
Field collection: company name, billing address, VAT number, PO, accounting contact, Incoterm if export
Cart building: Shopify draft order or ERP quote with contract price
PROFORMA-DOC issuance: PDF template, number PRO-YYYY-NNNN, validity date
Sending + instructions: "Informational document, awaiting your internal validation. Payment on deposit or final invoice according to PROFORMA-POLICY."
Validation follow-up: tag
pf_pending_validation, reminder at D+7 if silentConversion: PO received → payment link, bank transfer (see #322) or confirmed draft order → deposit/final invoice
QuickBooks pattern
Many tools start from an Estimate converted to a final invoice once the deal is confirmed (QuickBooks, proforma 2026). Same Shopify logic: draft order = proforma base, invoice app or ERP = final.
Workflow restrictions
Sending a proforma labeled "Invoice" without mentioning proforma. Promising delivery times not validated by ops. Accepting bank transfers without planning a deposit or final invoice.
Which PROFORMA macros for support and finance?
PROFORMA macros reduce back-and-forth communication with accounts receivable. Prefix PF-.
8 essential macros
PF-REQUEST: list of fields to provide (company name, VAT, PO, address, contact)
PF-SENT: "Proforma PRO-{num} attached, valid until {date}. Informational document prior to validation."
PF-UPDATE: "Revised proforma PRO-{num_v2}, replaces version {num_v1}."
PF-VS-DEVIS: "The quote is a commercial offer; the proforma formalizes amounts for your purchasing/customs department."
PF-ACOMPTE: "Deposit {pct} %: deposit invoice {num} issued after receipt of bank transfer."
PF-PAID-DEFINITIVE: "Payment received, final invoice {num} within 48 hours."
PF-EXPIRED: "Proforma expired on {date}. New version updated with current prices: please confirm?"
PF-EXPORT: Incoterm, customs value, EORI details if applicable
Required variables
{proforma_num}, {valid_until}, {amount_ht}, {amount_ttc}, {po_number}, {payment_instructions}. Link support templates (#34).
How to manage client validation, down payments, and order conversion?
The validation before payment phase concentrates the most repetitive tickets.
Scenario A: internal buyer validation
Client sends signed PO or "good for agreement" email. Support tags pf_validated, transfers to finance for payment link or bank transfer details. Uncap: Shopify Plus B2B accounts see invoices and payment history in the portal (Uncap, B2B payments 2026).
Scenario B: deposit required
Proforma mentions 30% upon ordering. Infos Entreprises: issue regulatory deposit invoice, not just proforma (Infos Entreprises 2026). Keobiz: VAT is due upon receipt of deposit, deposit invoice is mandatory for deduction (Keobiz, deposits 2026).
Scenario C: full payment before shipping
Export or custom-made. Client pays on proforma basis: finance issues final or deposit invoice within 48 hours, then order goes to fulfillment after bank reconciliation.
Scenario D: expired proforma
Prices or stock have changed. Macro PF-EXPIRED + new proforma. Do not honor old amount without sales validation if margin is impacted.
Shopify order statuses
Draft order "Proforma sent" → "Awaiting payment" → "Paid". Internal note: PRO- number and client PO.
How to handle export, customs, and documentary letters of credit?
Export proforma requests require specific mentions and SLAs distinct from metropolitan France B2B.
Mandatory export fields
Incoterm (EXW, FOB, DAP, DDP) and place of risk transfer
Net/gross weight, packages, origin of goods
HS Code per line if required by customs
Currency and rate if billing is outside EUR
Seller and buyer EORI if applicable
Bank and L/C
Factureproforma.fr: documentary credits often require a proforma to open the letter of credit (Proforma Invoice, 2026 guide). Escalation to finance + export manager, no support-only resolution.
Export VAT
EU B2B export proforma: reverse charge VAT if valid intra-community number (cross-reference #160). Outside EU: exempt export, legal mention on PROFORMA-DOC. Support collects VAT number, finance validates in VIES.
SLA Deadline
Export: 4 business hours if urgent customs file. PF-EXPORT template with list of attachments (customer Kbis if first purchase).
Which vertical playbooks for pro equipment, cosmetics, and mixed DTC?
The priority proforma intents vary depending on the B2B/B2C mix.
Professional equipment / B2B light
Peak pf_request_new and pf_convert_order. Net terms sometimes after first proforma + deposit. Link payment terms (#234).
Cosmetics / pharma light
Batches, expiration dates, minimum quantities on proforma. Regulatory statement of the destination country. Quality validation before issuance if exporting.
Custom-made / personalization
Proforma is almost systematic before production. 50% deposit pattern. Link personalized products.
DTC with a few pro accounts
Risk: B2C support treats proforma as a WISMO invoice. Route the proforma tag to the finance queue as soon as a SIRET or "purchasing department" is detected.
Marketplace seller
Proforma out of scope for standard marketplace: redirect to direct B2B channel if policy allows.
Which KPIs should be measured on the pro forma flow?
Measure delay and proforma conversion, not gross finance ticket volume.
Monthly KPIs
pf_sla_issue: % of proformas issued within SLA policy
pf_conversion_rate: validated proformas / issued proformas
pf_time_to_payment: days between proforma sending and payment receipt
pf_revision_rate: revised proformas / total (collection quality)
pf_paid_no_invoice: payments without final invoice within 48 hours (target 0)
pf_expired_lost: lost deals due to expired proforma
pf_ticket_touch: average messages per proforma file
Monthly finance × support review
Top reasons for pf_mentions_fix → enrich template. pf_paid_no_invoice > 0 → accounting process alert. Miva recommends end-to-end testing PO → proforma → invoice (Miva, B2B invoice 2026).
How does Qstomy qualify and accelerate proforma requests?
Qstomy does not replace the finance PDF issuance, but automates the collection, qualification, and tracking of PROFORMA-INTENT.
Capabilities
Intent
pf_request_new: conversational form with PROFORMA-POLICY fieldsAuto-distinction between proforma vs. final invoice vs. quote
File status: pending / sent / validated / paid
Customer reminder if validation is pending at D+5
Finance escalation with structured payload (SIRET, PO, amount)
Pre-filled PF-* macros from Shopify draft orders
DTC Encrypted Scenario
Pro equipment brand, 22% B2B revenue. Before #321: 47 proforma tickets/month, 3.2 days average issuance delay, 28% revisions of mentions, pf_conversion_rate 41%. After PROFORMA-WORKFLOW + Qstomy collection: delay 1.1 days, revisions 11%, pf_conversion_rate 58%, pf_paid_no_invoice 0 over 6 months.
