Invoice Finance vs R&D Tax Credit Advance
Invoice finance gets you money from invoices your customers have not paid yet, and you can use it all year. An R&D tax credit advance gets you part of an R&D tax credit before HMRC pays it, once for each claim. HMRC processed 92% of R&D claims within 40 days in 2023 to 2024 (HMRC, 2023 to 2024), so an advance helps most when a claim is large or held up by a compliance check.
Use invoice finance for the ongoing wait between sending an invoice and being paid. Use an R&D advance for the wait on an HMRC R&D tax credit claim. More detail and scope
