All 220 guides
Every guide opens with a route check: the stage, the data, the validation to expect, and the first check to make. Page 4 of 11, guides 61 to 80.
Multi-network strategy for sellers with many buyers
One internal model, several routes, and a routing table that decides by buyer, not by habit.
Network costs and contracts to check
What to check in a network or provider contract: scope, status, support, exit and data return.
Network failures and retries: a safe retry rule
Idempotent resubmission, duplicate detection and the retry window, agreed before live exchange.
Peppol ids and addressing: getting the recipient right
Participant identifiers, schemes and the service metadata lookup, and the error when an address is wrong.
Peppol network: how it works, in plain terms
Access points, service metadata, document types and the four-corner model, explained without vendor language.
Service metadata and capability lookup
How a sender learns what a receiver can accept, before the first invoice is sent.
B2B exchange explained: seller to buyer, without a public buyer in the middle
Private agreements, agreed formats and channels, and the exception handling that keeps a B2B exchange working.
Agreeing a B2B format and channel
Format, syntax, profile, channel, validation and test invoice, agreed in writing with each buyer.
B2B credit notes and adjustments
Full and partial credit notes, references to the original invoice, and the audit trail they create.
B2B disputes and short payments
How a disputed line, a short payment and a credit note relate, and how to keep the record clean.
B2B exchange monitoring: a daily view that catches failures
Sent, delivered, accepted, rejected and paid, as a daily count, with an owner for each exception.
B2B matching and approval workflows
Two-way and three-way matching, approval chains and the exception queue that decides payment speed.
B2B onboarding: a new buyer in order
Identifier, format, channel, test invoice, go-live gate, in that order, for each new buyer.
B2B self-billing arrangements
When the buyer issues the invoice, what the agreement must cover, and how the seller checks it.
B2B volume and batch invoicing
Batches, batch acknowledgements and the partial failure inside a batch, handled without re-sending the whole batch.
B2B vs B2G invoicing: start from the buyer
The distinction starts with the buyer: a private buyer agrees a route, a public buyer may be obliged to receive a standard invoice.
Buyer requirements and supplier portals
Portals, onboarding forms and buyer-specific rules, and how to keep one internal model behind many portals.
B2G and public procurement explained: selling to a public buyer
Receiver obligations under Directive 2014/55/EU, standard invoices, profiles and the portals that receive them.
B2G contract references and order numbers
Why a public buyer invoice without the right contract or order reference is rejected, even when the data is valid.
B2G framework agreements and invoicing
Invoicing under a framework agreement: call-off references, lots and the limits that bind each invoice.
