The award is the start of the paperwork, not the end of it
Founders treat a successful grant application as the finish line. The funding agreement treats it as the opening entry in a file that will be read by people who were not in the room when the money was spent.
German public research funding is unusually explicit about this. The Nebenbestimmungen, the standard conditions attached to almost every project, are a contract about documentation as much as about money. Under ANBest-P-Kosten, the applicant accepts that the awarding body, the audit court and the European Commission can all inspect the project, and that the burden of proof sits with the recipient rather than with the agency.
That single sentence changes the shape of the work. Everything spent has to be reconstructible years later by a stranger with no memory of the project.
Every invoice carries a number
When a grant is approved, the project receives a Förderkennzeichen, a funding reference code. That code has to appear on every invoice and every payment document belonging to the project. It is the string that lets an auditor pull one line out of a company's accounting system and attach it to one approved budget position.
Without it, a perfectly legitimate EUR 40,000 hardware purchase is an unexplained transaction inside an audited company. With it, the same invoice is evidence. That is the whole test. The difference costs nothing except discipline. Putting the code in the reference field is the single most common finding in post-project audits. It is also the cheapest one to avoid.
6 years of numbers, 10 years of receipts
Two clocks run after a project ends. The first is reporting: the Kennziffern, the indicator returns, are submitted annually and continue for 6 years after the project closes. The second is retention: original documents, invoices, contracts, timesheets and proof of payment are kept for 10 years.
Ten years is longer than most companies keep anything. Software is replaced. Accountants change. A filing cabinet goes to storage, and 3 years later the storage unit is emptied. An applicant who has not asked where the ten-year file physically lives has effectively agreed to keep a record they have no plan for.
The changes you must report before anyone asks
The conditions require immediate notification of material changes to a funded project. A partner leaving. A work package slipping. A site changing. A cost position moving materially. The reporting is not discretionary. It is not annual. It is immediate, in writing, and it applies whether or not anybody asks.
Read together, the post-award rules describe something more interesting than bureaucracy. They assume the recipient will be audited by someone who has never met them, and they push the entire burden of explanation onto the file. The probability of a late or unreported change becoming a finding is what the notification clause exists to reduce.
Three quotes, or the cost is yours
Procurement inside a funded project is also documented. Purchases above a threshold need comparative offers, in most programmes 3 independent quotes at minimum. The quotes must be genuinely independent, and the rule that decides independence is usually role overlap: the same person who signs off on one supplier's quote cannot be the person who owns the other supplier's file.
Personnel is where the arithmetic gets strict. A research institution claiming up to 90 per cent of an eligible position still has to hold a 20 per cent own-share floor on personnel costs, and the split between the non-profit and the commercial side of the house has to be kept separately, invoice by invoice.
The file is the product
Every number in the claim has to trace to a primary source inside 48 hours. Not to a memory. Not to an estimate. Not to a colleague who has since left.
Awarded funding is a public statement that somebody competent has read you. The file is what you leave behind to prove that reading was correct. 12 pages get you funded. 10 years of paperwork keep you funded.
The cost of building that file is paid in hours spread across the project. The cost of rebuilding it at an audit is paid in the same hours, at 4 times the price, by people who no longer work for you.
