For a legitimate made-to-order sale that starts on Facebook Marketplace or Messenger, freeze the specification in writing, collect a customer-specific deposit through a verified business checkout, record approval changes and collect the balance before handover. Do not use an external link to bypass an available protected Marketplace checkout for an ordinary listing.
This workflow is for makers selling custom furniture, signs, cakes, art or other commissioned goods. Its original asset is a five-state order ledger that keeps the social conversation, payment and build status aligned.
Decide Whether an External Workflow Is Appropriate
Use Meta's available on-platform checkout and protection route when it covers the listed item and transaction. Moving an ordinary buyer outside that route can remove protections and look like the scams both sides are trying to avoid.
An external customer-specific workflow can fit a genuinely custom order when the final specification, price and staged payment do not exist in the original listing. Meta's 2025 payment-scam guidance warns about fake storefronts, non-delivery and overpayment claims backed by fake receipts. Keep the Marketplace conversation intact, use a business identity and verify payment only in your authenticated provider view.
Use a Five-State Order Ledger
| State | Required record | Payment action |
|---|---|---|
| Enquiry | buyer, listing and requested variation | none |
| Quoted | specification, total, validity and delivery method | send customer-specific deposit link |
| Funded | authenticated deposit, amount and currency | reserve materials/build slot |
| Approved | dated design or proof plus changes | issue balance invoice |
| Released | authenticated balance and handover evidence | deliver or ship |
Never promote an order because a screenshot, email or buyer phone says “paid.” Match seller account, transaction status, amount, currency and order reference inside the connected provider.
Worked Example: A €600 Custom Table
The seller records dimensions, timber, finish, leg style, delivery area and one drawing revision. The quote is €600 with a €180 production deposit and €420 balance due after the buyer approves completion photos and before delivery.
The deposit is not a blank permission to change the specification. If the buyer adds a larger top costing €90, record a dated change order and make the new balance €510. If the maker cannot supply the agreed timber, pause and agree the substitute or refund route rather than quietly changing the product.
Whether a deposit is refundable depends on the disclosed terms and applicable local law. Explain material commitments, cancellation stages and remedy routes before payment; this workflow is operational guidance, not legal advice.
Make the Checkout Verifiable
Send one customer-specific URL with business name, exact product, staged amount, currency and contact route. Ask the buyer to check the domain independently. Never request an “account upgrade” payment, gift card, verification transfer or refund of an alleged overpayment before the original payment is authenticated.
For pickup, record the agreed person, date, item ID and signed or messaged acceptance. For shipping, use the address and evidence requirements shown by the provider and do not promise protection that the transaction is not marked eligible for.
Connect Messenger to PayRequest
Use the Facebook payment-link workflow to create the named deposit destination and PayRequest invoicing for the approved balance. Keep the same order reference across quote, checkout, invoice and handover.
The useful control is not merely pasting a link into Messenger. It is refusing to start on an unverified screenshot, refusing to deliver before the balance succeeds and keeping one record that explains exactly what the buyer ordered and paid for.
