Why It Took a Tax Office to Make Invoices Machine-Readable

In 1995, Inc. magazine profiled Belly Basics, a maternity-clothing maker with $1.5 million in annual sales, a quarter of them to Federated Department Stores. Federated set a deadline for exchanging orders and invoices as structured data, which its computers could file without anyone retyping. The software would have cost Belly Basics about $10,000, so the company hired a middleman at roughly $40 an order to turn Federated's electronic orders into faxes and its own invoices into Federated's format. Federated got its data, and Belly Basics went on working from paper.

Neither side did anything foolish, and their arrangement explains much about the next thirty years. The standards already existed: the American invoice format, X12 810, dates to 1983, and the UN approved rules for an international equivalent, EDIFACT, in 1987. Suppliers lacked a reason to want them. In a 1989 survey, 63% of firms exchanging data electronically said they had started because their most important customer asked. The firm doing the asking got the data, and the firm being asked paid for it.

That arrangement had a ceiling. A retailer could compel only its own suppliers, so adoption spread in clusters around large buyers, and a small firm could buy its way in, as Belly Basics did, without changing how it worked. PDFs later let firms stop printing invoices without producing any data. By 2016, only 15% of French firms with ten or more employees sent machine-readable invoices, against an EU average of 18%.

The ceiling broke when the demand came from the one party every business already answers to. Firms that charge value-added tax, a sales tax collected at each step of a supply chain, report to the tax office. Unlike Federated, a tax office buys nothing and cannot be dropped as a customer. It gains from invoice data by catching fraud, and it can reach every firm at once. Brazil started with cigarettes and fuel in 2008; Mexico and Italy followed in 2014 and 2019. For Italy's first year, the European Commission credited €945 million in blocked fraudulent claims, though it could not isolate how much was e-invoicing's doing.

France's version took effect this September, two years later than planned, after the state had dropped a proposed free public portal. Current law requires firms to use private platforms the state certifies, though officials point to free offers aimed at small firms. Every firm must now be able to receive e-invoices; only large and mid-sized firms must issue them, until smaller ones join in September 2027.

Evidence of actual use is thinner and comes mostly from the government itself. More than 20 million invoices have been exchanged, and 75% of firms that file VAT returns have chosen a receiving platform. Large companies report that platforms don't always connect cleanly. No penalties apply before year's end, and methods for measuring savings are still being designed.

The Federated comparison holds up to a point. Whoever demands the data still receives it, and senders still pay intermediaries to produce it. It breaks on who else benefits. Belly Basics sent structured data to one customer and got faxes back. A small French firm is now owed structured invoices by its larger suppliers, and by smaller ones from September 2027 if the schedule holds, produced at their expense. Factur-X, the Franco-German format, builds in the conversion Belly Basics paid a middleman for, wrapping the data inside an ordinary PDF so recipients can use either. Perhaps that is part of how a standard becomes ordinary: it stops requiring anyone to work differently, so reading the data and printing the page both count as compliance.
