Building materials
Building materials is one of the categories where the mandate meets an invoicing process that was never designed to be machine-readable. Deliveries happen before paperwork, quantities get adjusted on site, and a single project can generate months of partial billing against one order. None of that is a problem in itself — but all of it has to be expressed in structured data that validates on the first attempt.
Material goes out against a delivery note, quantities are confirmed at the gate, and the invoice is raised afterwards against what was actually received. The invoice therefore inherits data from a document that often lives outside the accounting system entirely.
Short deliveries, site rejections, returns of damaged stock and part-loads are routine. Credit notes and adjustments are not an exception path here — they are a normal weekly occurrence, and each one is a structured document with its own requirements.
Progressive billing against a supply agreement means many invoices referencing one commercial arrangement, often with retention and staged release. The reference data linking them has to be consistent across every document.
Tonnes, cubic metres, pieces, bundles, linear metres — sometimes more than one on the same invoice line's history. Structured invoicing requires these to be expressed consistently, and legacy records frequently are not.
Typically an accounting package handling the ledger, with deliveries, stock and site paperwork tracked in a separate system or in spreadsheets. The invoice data is assembled across both.
The same contractor appearing under several names, sites recorded as separate customers, and tax registration numbers held inconsistently or not at all. This surfaces immediately during validation.
Rate agreements, project-specific pricing and discount structures often live in correspondence rather than in the system that raises the invoice.
Structured B2B invoices require the buyer's details to be present and correct. Supplier ledgers built over years rarely have them complete, and cleaning that is groundwork, not a technical task.
Because adjustments are frequent here, the way they are raised and referenced needs to be settled early rather than discovered during the first month-end after go-live.
If the operational system is where the truth lives and the accounting system is where the invoice is raised, the mapping has to account for that split explicitly.
This describes the pattern we see in this category, not a claim about any specific business. Your environment is established during assessment, not assumed from your industry.
